In the present embodiment, communication unit 22 via the Internet 11, conveyer belt (carousel) load mode that is used to repeat to transmit transmits metadata with the unit of transfer that is called module.Fig. 3 shows the basic structure as the module of delivery unit.This module is made of the HTTP many parts header (multipartheader) and the follow-up entity of regulation in HTTP (HTTP)/1.1.In this embodiment, entity also by a plurality of parts, be that many parts 1～4 constitute.That is, use many parts form of four parts of configuration in an entity to transmit the metadata of forming by attribute information ERI, authority information LLI and control information NCI.
And then represent many parts form HTTP many parts header be many parts 1～4, each many parts all is made of http header, CRLF (carriage return/newline) and entity.The Content-Location of the position (for example, the position on content server 14 is such as http://huge/doc/abc.eri) of http header storage represent content, perhaps the type of represent content is (for example, such as text/xml; The content type of chrset=" UTF-8 ") Content-Type.
Entity stores the Resources list of many parts 1, the entity stores attribute information ERI of many parts 2, the entity stores authority information LLI of many parts 3, and the entity stores control information NCI of many parts 4.
ERI (entering resource information (Entry Resource Informatin)) is the content build-in attribute information with reference to destination or transmission form that does not rely on object content.LLI (permission chain information (License Link Information)) is the authority information such as the information relevant with permission that is used for object content or authority protection.NCI (Web content control information) receives relevant control information with stream.Every metadata is all write as with XML (extend markup language).
Each many parts all has the length of being represented by resourceLength, and its http header has the represented length by headerLength.
Fig. 4 shows the grammer of the Resources list that writes in many parts 1.Grammer X-arib-resourceList{} is standardized with the standard of writing of ARIB (radio industry and commercial guild).ARIB is the tissue by " radio wave effectively utilizes promotion center (the center of promotion of the efficient use of theradio spectrum) " of Radio Law regulation by Japanese general affairs minister (the Minister ofInternalAffairs and Communications) appointment, this tissue is held comings and goings, for example investigation, research and development relevant with effective use of radio wave and the technical research of cooperating with the standardization body in communication/broadcast world.
In X-arib-resourceList{}, the number of the resource that the num_of_resources representative is comprised in same module.Under the situation of this execution mode, because three metadata store being made up of attribute information ERI, authority information LLI and control information NCI are in a module, so write three resourceInfo ().Therefore, as shown in Figure 3, the Resources list is made of the resourceInfo () of resourceInfo (), the authority information LLI of number of resources, attribute information ERI and the resourceInfo () of control information NCI.
In the present embodiment, in resourceInfo (), as shown in Figure 4, with the Text_char of necessary number, write resourceInfoLength, resourceOffset, headerLength, resourceLength, resourceTypeValue, reserved_future_use and resourceNameLength.
As shown in Figure 3, the length of resourceInfoLength every resourceInfo of representative ().ResourceOffset representative from the top of every resourceInfo () to the length on the top of corresponding information.That is, in the resourceInfo of attribute information ERI (), represent the length on top of attribute information ERI in the entity of many parts 2, top of the resourceInfo () of dependency information ERI; In the resourceInfo of authority information LLI (), representative from the top of the resourceInfo () of authority information LLI to the entity of many parts 3 length on top of authority information LLI; And in the resourceInfo of control information NCI (), representative from the top of the resourceInfo () of control information NCI to the entity of many parts 4 length on top of control information NCI.
HeaderLength represents the length of the http header of every part.ResourceTypeValue comprises Content-Type.Reserved_future_use reserves for use in the future.The resourceNameLength representative is by the length (size) of the represented file name of Text_char.Text char is the title of file and the position of represent content (Content-Location).
In this mode, in the present embodiment, attribute information ERI, authority information LLI and control information NCI are stored in the module of using many parts form and are sent out.Therefore, compare, suppressed that only one of them does not arrive the incident of receiving system 12 with the situation that three associated metadatas use module independently to send separately respectively.In addition, also be easy to separated/extracted attribute information ERI, authority information LLI and control information NCI from various piece.Therefore, guaranteed that metadata can send and can be received device 12 from content server 14 and utilize.Therefore, except the normal reproduction of the content that provided via the Internet 11, can also carry out such as F.F. or the special reproduction that falls back.
Fig. 5 and Fig. 6 show the instantiation of attribute information ERI.As shown in FIG., the title of the coded system of the resolution of the URL of the summary of the title of the identification of date created, creation-time, encrypted content, content, content, content (URL(uniform resource locator)), chapter number, chapter starting point (relatively constantly), chapter title, video ES (elementary stream), video ES, audio ES channel number, audio ES, captions ES number, captions ES language etc. are set to attribute information ERI.
It should be noted that in Fig. 5 and Fig. 6, " string " represents character string, " bool " represents true/vacation, and " ui (signless integer) 4 " expression signless integer.The maximum that maximum representative is available, and frequency is illustrated in the corresponding information and can carries out the number of times that writes.For example, the chapter title can be represented by 96 characters nearly, and has 1～99 frequency.The audio ES channel number represented by maximum two signless integers, and has 0～4 frequency.The identification of encrypted content is represented by maximum numbers, and is had frequency 1.
Fig. 7 shows the instantiation of authority information LLI.As shown in FIG., the identifying information of the URI of date created, creation-time, DRM server (unified resource identifier), CA (conditional access), license ID etc. are set to authority information LLI.
Fig. 8 shows the instantiation of control information NCI.As shown in FIG., the value of date created, creation-time, stream protocol, FEC (forward error correction (Forward Error Correction)) mode and parameter, speed change value, chapter starting point (the relative moment), bit rate, the byte number of content, the validity of server S talling, time search consistent validity, the validity of flow control information etc. and are set to control information NCI.
In the present embodiment, the value corresponding to the speed change value of reproduction speed during special reproduction is designated as data volume, specifically, is designated as byte number.Promptly, for example, in (under the situation that F.F. is reproduced) under the situation that the forward direction speed change is reproduced, be in that the locational data of displacement 512kB are designated to be used for two times of speed and to reproduce, and the designated triple speed that is used for of locational data that is in displacement 512 * 8kB reproduces.In (under the situation about reproducing that falling back) under the situation about reproducing to the reverse direction speed change, be in that the locational data of displacement 512kB are designated to be used for negative two times of speed and to reproduce, the locational data of displacement 512 * 8kB are designated to be used for negative triple speed and to reproduce and be in.That is, the unit quantity 512kB of the view data under the compressive state specifies the value of its integral multiple as benchmark.This unit quantity can suitably determine, perhaps can be set to the data volume of the specific reproduction duration (for example, about 1 second reproduction duration) corresponding to the average image.And this data volume can be set to the data volume under the compressive state.This makes and is easy to carry out the rapid data retrieval.
Fig. 9 shows the transformation of playback mode.When the user of receiving system 12 will receive from content that content server 14 provides, he was at first via the portal site of the Internet 11 accessed content servers 14.At this moment, receiving system 12 is in " inlet top (PortalTOP) " state, and shows inlet picture as shown in figure 10.

In step S141, the received metadata of shared storage 218 storages.This makes and there is no need to repeat independently to preserve metadata (its data volume is very big) in each module, and allows metadata to be utilized as required.
In step S165, module dtIfSilk 213 will read the required pointer notification module dtMintX 219 of metadata from shared storage 218.When receiving this pointer in step S201, in step S202, module dtMintX 219 is further with this pointer notification module MintProxy 220.In this way, each module only needs to carry out the notice of the little pointer of data volume, thereby fast processing is possible.
When receiving this pointer in step S221, in step S222, module MintProxy 220 carries out the processing of reading metadata from shared storage 218 based on this pointer.That is, read when request when receive this in step S142, the metadata that shared storage 218 will be stored in wherein offers module MintProxy 220.
In step S223, module MintProxy 220 is sent to the metadata that is read the module xDTVSrv 269 of processing unit EEGS 251.Carry out by module MintProxy 220 owing to send the processing of metadata (its data volume is very big), so remaining module can be carried out other processing alone.
When receiving metadata in step S281, in step S282, module xDTVSrv 269 makes received metadata be sent to module xDTPInvoker 268 in same module 267.In step S301, module xDTPInvoker 268 receives this metadata.In this mode, metadata is preserved by module xDTPInvoker 268.Therefore, can come the reproduction operation of control content based on this metadata.
In step S121, accepted indication from user's reproduction content.Therefore, when finishing the processing of obtaining metadata in the above described manner, module xDTPInvoker 268 will operate from the operation of carrying out function of browse and switch to the operation that is used to obtain and reproduce content.Particularly, under the situation of this execution mode, module xDTPInvoker 268 is by before after this described content obtains processing in beginning, stops to carry out the operation of the module dtSilk 211 of function of browse, carries out this switching.
That is, make as before being used to reproduce module dtNetPlayer 222 activation of reproduction of content device, the operation of module xDTPInvoker 268 request module dtSilk 211 stops (kill) (request inactive state).When receiving this request in step S261, in step S262, module xAppStateMgr 263 is sent to module TVC216 with this request.Specifically, this request is sent to module TVC 216 from module xAppStateMgr 263 by module MoviePlayer 264, module xPlayerEngine 265, module xNetEquipmentSrv266 and module DtNetEquipment 221.
When receiving this operation when stopping to ask in step S241, in step S242, module TVC 216 carves in due course and this operation is stopped request exporting module dtIfSilk213 to.When receiving this operation when stopping to ask in step S166, in step S167, module dtIfSilk 213 further stops operation request and exports module dtSilkCore 212 to.In step S25, module dtSilkCore 212 receives this operation and stops request.This make module dtSilk 211 (being module dtSilkCore 212 and module dtIfSilk 213) thus for inactive shut-down operation.
In this mode, owing to carried out the switching of operation, thus guaranteed to obtain content, and can not cause that each program (module) is made mistakes in subsequent treatment.In addition, under the situation that the operation of module dtSilkCore 212 and module dtIfSilk 213 stops, can reducing the capacity of stored program memory during operation, and can realize the reduction of power and cost.
After having carried out hand-off process in the above described manner, in step S303, module xDTPInvoker 268 request content servers 14 introductory contents promptly start reproduction of content.When receiving this boot request in step S263, in step S264, module xAppStateMgr 263 sends boot request to module MoviePlayer 264.
When in step S101, receiving this boot request, module MoviePlayer 264 channeling conducts and the necessary metadata of request content server 14 transmission transmission contents in step S102.When in step S304, receiving this transmission request, in step S305, module xDTPInvoker 268 reads request content server 14 and sends the necessary metadata of content from the metadata of being preserved the processing of step S301, and export it to module MoviePlayer 264.
When receiving this metadata in step S103, in step S104, module MoviePlayer 264 is according to the boot request of metadata output for content server 14.This request is sent to module dtNetPlayer 222 from module MoviePlayer 264 by module xPlayerEngine 265, module xNetEquipmentSrv 266 and module DtNetEquipment 221.
When in step S61, receiving this boot request, active module dtNetPlayer 222, and in step S62, export boot request to module HttpClient 223.When receiving this boot request in step S45, in step S46, module HttpClient 223 is sent to content server 14 via the Internet 11 with boot request.
When the communication unit 22 by content server 14 received this request in step S3, in step S4, control unit 23 read the content-data that is stored in the given content in the memory cell 21, i.e. flow data.Communication unit 22 is sent to receiving system 12 via the Internet 11 with this flow data.
When receiving this flow data in step S47, in step S48, the module HttpClient 223 of receiving system 12 exports it to module dtNetPlayer 222.Module dtNetPlayer 222 makes receiving system 12 based on this flow data and display image.
By the way, exported content, thereby the user can watch this content by user's appointment.
When reproduction of content stops, in step S5, control unit 23 output terminations of content server 14 notice.Communication unit 22 should stop notice via the Internet 11 and export receiving system 12 to.
When receiving this termination notice in step S49, in step S50, the module HttpClient 223 of receiving system 12 exports this notice to module dtNetPlayer 222.When in step S64, receiving this termination notice, module dtNetPlayer 222 is handled for inactive and termination moving-image reproducing.At this moment, state becomes " time-out ".
In addition, in step S65, module dtNetPlayer 222 will stop notice and export module MoviePlayer 264 to.This notice is provided to module MoviePlayer 264 from module dtNetPlayer 222 by module DtNetEquipment 221, module xNetEquipmentSrv 266 and module xPlayerEngine 265.
Receive this termination notice in step S105 after, in step S106, module MoviePlayer 264 will stop notice and export module xAppStateMgr 263 to.When receiving this termination notice in step S265, in step S266, module xAppStateMgr263 will stop notice and export module TVC 216 to.This termination notice is sent to module TVC 216 from module xAppStateMgr 263 by module xNetEquipmentSrv 266 and module DtNetEquipment 221.
When receiving this termination notice in step S243, in step S244, module TVC 216 exports to give an order to module dtIfSilk 213: stopping being back to last mode of operation of particular moment cancellation operation.When receiving this return instruction in step S168, in step S169, module dtIfSilk 213 exports return instruction to module dtSilkCore 212.In step S26, module dtSilkCore 212 receives this return instruction.In this mode, active module dtSilkCore 212 and module dtIfSilk 213 once more, and setting operation state.
In the above described manner, the operation of module dtNetPlayer 222 stops (becoming inactive), and instead, makes module dtSilkCore 212 and module dtIfSilk 213 enter mode of operation (activity) (their are recovered) once more.This has guaranteed after this can carry out similar operation immediately when the reproduction of other guide is carried out in indication.Alternatively, can carry out other the processing that utilizes function of browse immediately.
The user can suspend the image that is reproducing maybe can cancel this time-out.Then, will the processing that make reproduced image enter halted state and cancel this halted state be described with reference to Figure 21.
When the user indicated time-out by the pause button 56 of remote controller 13, in step S421, module xlmmControl 270 accepts this operation and request module MoviePlayer 264 execution suspend.When receiving this request in step S401, in step S402, module MoviePlayer 264 will suspend request and export module xPlayerEngine 265 to.When receiving this request in step S381, in step S382, module xPlayerEngine 265 will suspend request and export module dtNetPlayer 222 to.When receiving this request in step S361, in step S362, module dtNetPlayer222 request module HttpClient 223 ends (close) and reproduces.
When accepting this termination in step S341, in step S342, module HttpClient 223 will ask HTTP tear down (time-out) to export content server 14 to.When accepting this request in step S301, content server 14 is supspended and is reproduced operation and halted state is set.
On the other hand, in step S63, module dtNetPlayer 222 returns instruction is successfully sent in response " return " from representative to module xPlayerEngine 265.When receiving response " return " in step S383, in step S384, module xPlayerEngine265 further will respond " return " and export module MoviePlayer 264 to.In step S403, module MoviePlayer 264 receives response " return ".Thus, module MoviePlayer 264 detects normally finishing of pausing operation.
When the user indicated reproduction by the reproduction button 55 of further remote controller 13, in step S422, module xlmmControl 270 accepts this operation and request module MoviePlayer 264 carries out reproduction.When receiving this request in step S404, in step S405, module MoviePlayer 264 request of will reproducing exports module xPlayerEngine 265 to.When receiving this request in step S385, in step S386, module xPlayerEngine 265 request of will reproducing exports module dtNetPlayer 222 to.When receiving this request in step S364, in step S365, module dtNetPlayer222 request module HttpClient 223 carries out and reproduces.Particularly, output is used to obtain the view data request HTTP GET of (being used for reproducing).
When accepting request HTTP GET in step S343, in step S344, module HttpClient 223 further will ask HTTP GET to export content server 14 to.When accepting request HTTP GET in step S302, content server 14 recovers to reproduce operation.That is, content server 14 is from memory cell 21 reading flow data, and in step S303, it is output as http response.
When receiving http response in step S345, in step S346, module HttpClient 223 exports http response to module dtNetPlayer 222.When receiving this http response in step S367, module dtNetPlayer 222 reproduces the flow data that wherein comprises.
Then, will operation during the special reproduction be described with reference to Figure 22.As illustrated, for example,, start this operation when reproducing when operating period makes the special reproduction indication based on the operation of special reproduction button 57 with reference to figure 9.
When the user indicated special reproduction, in step S621, module xlmmControl270 accepted this indication.Module xlmmControl 270 will indicate corresponding operation signal FF/REV to export module MoviePlayer 264 to the special reproduction of being accepted.For example, when operation fast forward button 58 or rewind button 59 and indication were reproduced as the speed change of special reproduction, indication was reproduced with the command speed speed change.When receiving this operation signal in step S581, in step S582, module MoviePlayer 264 is to the necessary metadata of module xDTPInvoker 268 request control special reproduction.When receiving this request in step S601, module xDTPInvoker 268 extracts from the metadata of wherein storage and realizes the necessary transfer system metadata of special reproduction, and, in step S602, send it to module MoviePlayer 264.
When receiving this metadata in step S583, in step S584, module MoviePlayer 264 produces and is used to be sent in the requests for content that realizes speed change reproduction (with the speed change reproduction speed of appointment) necessary position and have necessary amount.That is, calculate the speed change of carrying out appointment from current reproduction original position and reproduce the necessary data volume (byte number) of skipping, and in request middle finger be positioned to be shifted a certain amount of data of position of this data volume.As mentioned above, in this embodiment, it is available that speed change is reproduced in-3 times～+ 3 times the scope, and skipping data volume in each speed change is reproduced is set to: for example, be used for negative triple speed-512 * 8kB, be used for negative two times of speed-512kB, 512 * 8kB of being used for the 512kB of two times of speed and being used for triple speed.That is the data volume of the speed during the skipping data volume and be set to reproduce of flow data, according to speed change.And this data volume is set to steady state value.The result, for example, reproduce for two times of speed, request sends a certain amount of data that begin from the position with respect to last reproduction original position displacement 512kB, and reproduce for triple speed, request sends a certain amount of data that begin from the position with respect to last reproduction original position displacement 512 * 8kB.
When receiving this special reproduction request in step S561, in step S562, module xPlayerEngine 265 further is sent to module dtNetPlayer 222 with this special reproduction request.Specifically, the special reproduction request is transferred into module dtNetPlayer 222 by module xNetEquipmentSrv 266 and module DtNetEquipment 221.When receiving this request in step S541, in step S542, module dtNetPlayer 222 further is sent to module HttpClient 223 with the special reproduction request.
When receiving the special reproduction request in step S521, in step S522, module HttpClient 223 requests send to be positioned at skips the described content position, that have given amount of data of skipping data volume.Promptly, by using starting point (it is in respect to last reproduction original position and reproduces the described position of skipping data volume of direction displacement to speed change) and end point (it is in respect to starting point to normal reproduction direction a certain amount of position that is shifted) to come specified scope, and request content server 14 is sent in the interior content of specified scope.This request is sent to content server 14 via the Internet 11.
In step S501, the communication unit 22 of content server 14 receives this request.In step S502, in response to this request, control unit 23 reads in flow data the specified scope from memory cell 21, and makes communication unit 22 send it to receiving system 12 as http response.
When receiving this stream in step S523, in step S524, the module HttpClient 223 of receiving system 12 sends it to module dtNetPlayer 222.When receiving this flow data in step S543, module dtNetPlayer 222 makes it be shown as the special reproduction image of appointment.That is, obtaining content corresponding to the amount of skipping of specifying the speed change reproduction speed, and its speed change is reproduced by user's appointment via the Internet 11.
As shown in figure 23, it is contemplated that, except the normal data that is used for normal speed reproduction, in content server 14, also prepared the exclusive data (such as being used for two times of fast exclusive datas of reproducing and being used for the exclusive data that triple speed reproduces) that is used for high-speed retrieval in advance.In this case, for example, reproduce request if send triple speed from receiving system 12, then content server 14 is selected to be used for the exclusive data that triple speed reproduces from pre-prepd data, and it is passed to receiving system 12.
Yet this can be increased in the data volume of preparing in the content server 14, and also can make needs increase the capacity of memory cell 21, causes cost to increase.
In addition, as shown in figure 24, it is also conceivable that the starting point and the end point that make content server 14 calculate necessary next reproducing part of high-speed retrieval.In this case, for example, when sending triple speed from receiving system 12 and reproduce request, content server 14 calculates starting point and the end point that triple speeds reproduce necessary next reproducing part, and the normal data that will be positioned at the position that is calculated passes to receiving system 12.
Yet this can increase the load on the content server 14, and can cause that requirement content server 14 has high-performance, causes cost to increase.
On the contrary, as in the present embodiment, receiving system 12 be provided with special reproduction during the corresponding content of the special reproduction speed amount of skipping, and request content server 14 sends a certain amount of data that are positioned at the position of skipping the set amount of skipping.This can reduce the load on the content server 14, and even can avoid high performance requirement, thereby can realize the reduction of cost.
Although receiving system 12 is provided with the amount of skipping independently regardless of the feature of content in aforementioned embodiments, the amount of skipping also can be provided with according to the feature of content.In this case, for example, the content server 14 in store tables that are used for each content item as shown in figure 25.
Time t0～t4 represents the recovery time.That is, as shown in figure 26, in the content by this table appointment, the data from position P0 to position P1 are with the period T1 of constant bit rate reproduction from time t0 to time t1.Then, similarly, the data from position P1 to position P2, the data from position P2 to position P3 and the data from position P3 to position P4 are reproduced period T2, the period T3 from time t2 to time t3 and the period T4 from time t3 to time t4 from time t1 to time t2 respectively.It should be noted that in Figure 26 abscissa representative is from the recovery time of starting point (time t0) beginning of content, and ordinate representative data position (byte location), perhaps in other words, from the data volume of starting point (position P0) beginning of content.
The bit rate of period T1 from time t0 to time t1 is by (P1-P0)/(t1-t0) determine, the bit rate of period T2 from time t1 to time t2 is by (P2-P1)/(t2-t1) determine, the bit rate of period T3 from time t2 to time t3 is by (P3-P2)/(t3-t2) determine, and the bit rate of the period T4 from time t3 to time t4 passes through (P4-P3)/(t4-t3) determine.
Each period bit rate of (i.e. period T1 from time t0 to time t1, the period T2 from time t1 to time t2, the period T3 from time t2 to time t3 and the period T4 from time t3 to time t4) is constant.That is, the coded system of content is VBR (variable bit rate) mode on the whole, and is CBR (constant bit rate) mode in each of period T1～T4.Therefore, calculate the necessary amount of skipping of speed change reproduction in each period easily.The amount of skipping that is calculated for each period and the described symbology of each speed change reproduction speed among Figure 25.
For example, two times of required amounts of skipping of speed reproduction are SK21 among the period T1 from time t0 to time t1, the amount of skipping among the period T2 from time t1 to time t2 is SK22, the amount of skipping among the period T3 from time t2 to time t3 is SK23, and the amount of skipping among the period T4 from time t3 to time t4 is SK24.Similarly, the required amount of skipping of triple speed reproduction is SK31 among the period T1 from time t0 to time t1, the amount of skipping among the period T2 from time t1 to time t2 is SK32, the amount of skipping among the period T3 from time t2 to time t3 is SK33, and the amount of skipping among the period T4 from time t3 to time t4 is SK34.
Under the situation of using such table, in above-mentioned Figure 19 and processing shown in Figure 20, the table that content server 14 will be used for content is sent to the receiving system 12 that sends requests for content as metadata a kind of (control information NCI's is a kind of).Therefore, in the step S301 of Figure 20, the table that constitutes metadata is preserved by module xDTPInvoker268 in the above described manner.Therefore, receiving system 12 can be provided with reference to the table that receives as a kind of of metadata and carry out specific speed change and reproduce the required amount of skipping accurately.
Figure 27 shows based on obtaining from content server 14 in this mode and being kept at the table the receiving system 12 and carrying out the operation of the execution mode under the situation that speed change reproduces.
When the user will carry out the speed change reproduction, the fast forward button 58 of the special reproduction button 57 in his remote controller 13 or rewind button 59 were with appointment speed change reproduction speed, and the appointment speed change is reproduced direction.When accepting this operation in step S281, module xlmmControl 270 will export module MoviePlayer 264 to the corresponding operation signal FF/REV of indication of the special reproduction that is used to carry out the certain content of being accepted.When receiving this operation signal in step S781, in step S782, module MoviePlayer264 is to the required metadata of module xDTPInvoker 268 request control special reproduction.This request also comprises the request for the table of the amount of skipping of the speed change reproduction period that is defined in given content.When receiving this request in step S801, in step S802, module xDTPInvoker 268 extracts from the metadata of wherein storage and realizes the necessary transfer system metadata of special reproduction, and sends it to module MoviePlayer 264.
When step S783 receives this metadata, in step S784, module MoviePlayer 264 will reproduce the original position request of obtaining and export module xPlayerEngine 265 to.That is the notice of the reproduction original position of the current data of reproducing of request.For example, suppose to have sent the indications of two times of speed reproductions among period T1 now from time t0 to time t1.As shown in the A part of Figure 28, when this moment, the reproducing part reproduced was part from position P0 to position P02 (when the data the part from position P0 to position P01 are reproduced as data the part from position P0 to position P02 when reproducing to carry out speed change), position P0 is set to reproduce original position.Similarly, when reproducing part is part from position P02 to position P04 (when the data the part from position P02 to position P03 are reproduced as data the part from position P02 to position P04 when reproducing to carry out speed change), position P02 is set to reproduce original position.When reproducing part is part from position P04 to position P06 (when the data the part from position P04 to position P05 are reproduced as data the part from position P04 to position P06 when reproducing to carry out speed change), position P04 is set to reproduce original position.
Obtain when request when receive this reproduction original position in step S761, in step S762, module xPlayerEngine 265 will reproduce original position and obtain and ask to export to module dtNetPlayer 222.When receiving in step S741 when reproducing original position and obtaining request, module dtNetPlayer 222 knows the reproduction original position owing to reproduce the control of operation, and the reproduction original position of detection in current reproducing part.In step S742, module dtNetPlayer 222 exports detected reproduction original position to module xPlayerEngine 265.When receiving this reproduction original position in step S763, in step S764, module xPlayerEngine 265 exports it to module MoviePlayer264.
In step S785, module MoviePlayer 264 receives and reproduces original position.Module MoviePlayer 264 has obtained the speed change value in step S781, and has obtained table in step S783.Therefore, module MoviePlayer 264 shows to be provided with and the amount of skipping of reproducing the corresponding speed change value of original position with reference to this.So, if sent the indication of the quick reproduction of carrying out two times of speed, and if the reproduction original position of data within period T1 from time t0 to time t1, then as shown in figure 25 the table in the institute conspicuous, SK21 is set to the amount of skipping.If the reproduction original position of data is within the period T2 from time t1 to time t2, then SK22 is set to the amount of skipping.If the reproduction original position of data is within the period T3 from time t2 to time t3, then SK23 is set to the amount of skipping.If the reproduction original position of data is within the period T4 from time t3 to time t4, then SK24 is set to the amount of skipping.
In step S786, module MoviePlayer 264 calculates the starting point and the end point of the content-data that will obtain from content server 14, and exports them to module xPlayerEngine 265.Starting point is set to reproduce the position that data volume is skipped in the direction displacement with respect to last reproduction original position to speed change, and end point be set to respect to starting point to the displacement of normal reproduction direction a certain amount of (under the situation in present embodiment, value position a).
For example, shown in the A part of Figure 28, if the dash area among the figure reproduces successively to realize the reproduction of F.F. speed change, so at first, starting point is set to position P0 and end point is set to position P01, and this position is at normal reproduction direction (dextrad in the drawings) distance and position P0 value a.If reproducing original position is position P0, then starting point is set to position P02, direction is reproduced (in the drawings with respect to reproducing original position (being position P0) to speed change in this position, dextrad) the displacement amount of skipping SK21, and end point is set to position P03, this position with respect to starting point (being position P02) to the normal reproduction direction value a that has been shifted.Then, similarly, if reproducing original position is position P02, then starting point is set to position P04, this position is reproduced the direction displacement amount of skipping SK21 with respect to reproducing original position (being position P02) to speed change, and end point is set to position P05, this position with respect to starting point (being position P04) to the normal reproduction direction value a that has been shifted.If reproducing original position is position P04, then starting point is set to position P06, this position is reproduced the direction displacement amount of skipping SK21 with respect to reproducing original position (being position P04) to speed change, and end point is set to position P07, this position with respect to starting point (being position P06) to the normal reproduction direction value a that has been shifted.
In the time will realizing falling back the speed change reproduction, if reproducing original position is position P06, then starting point is set to position P04, direction is reproduced (in the drawings with respect to reproducing original position (being position P06) to speed change in this position, left-hand) the displacement amount of skipping SK21, and end point is set to position P05, this position with respect to starting point (being position P04) to normal reproduction direction (the dextrad in the drawings) value that has been shifted a.Then, similarly, if reproducing original position is position P04, then starting point is set to position P02, this position is reproduced the direction displacement amount of skipping SK21 with respect to reproducing original position (being position P04) to speed change, and end point is set to position P03, this position with respect to starting point (being position P02) to the normal reproduction direction value a that has been shifted.If reproducing original position is position P02, then starting point is set to position P0, this position is reproduced the direction displacement amount of skipping SK21 with respect to reproducing original position (being position P02) to speed change, and end point is set to position P01, this position with respect to starting point (being position P0) to the normal reproduction direction value a that has been shifted.
When receiving starting point and end point in step S765, in step S766, module xPlayerEngine 265 exports starting point and end point to module dtNetPlayer222.When receiving them in step S743, in step S744, module dtNetPlayer 222 exports starting point and end point to module HttpClient 223.
When receiving starting point and end point in step S721, in step S722, module HttpClient 223 specifies a scope by using received starting point and end point, and will ask HTTP GET to export content server 14 to.That is, send and be used for obtaining being positioned at the request of a certain amount of data of skipping the position of data volume (byte number) (it reproduces necessary for speed change of carrying out appointment) with respect to last reproduction original position displacement.
In step S701, the communication unit 22 of content server 14 receives this request.In step S702, in response to this request, control unit 23 reads flow data the specified scope from memory cell 21, and makes communication unit 22 send it to receiving system 12 as http response.
When receiving this stream in step S723, in step S724, the module HttpClient 223 of receiving system 12 sends it to module dtNetPlayer 222.When receiving this flow data in step S745, module dtNetPlayer 222 makes it be shown as the special reproduction image of appointment.That is, obtaining content, and its speed change is reproduced by user's appointment with the corresponding amount of skipping of speed change reproduction speed of appointment via the Internet 11.
Then, the processing after the repeated execution of steps S784 is reproduced to finishing or sent to stop order up to the speed change of carrying out content.Promptly, for example, data from position P0 to position P01 in having obtained the A part of Figure 28 in the above described manner and reproduce after, obtain and reproduce the ensuing data of having skipped the amount of skipping SK21 from position P02 to P03, and further obtain successively and reproduce skipped the amount of skipping SK21, the data from position P04 to P05 and data from position P06 to P07.Thereby, carried out the speed change reproduction.
Shown in the B of Figure 28～D part, among the period T2 from time t1 to time t2, the amount of skipping is SK22, and obtains successively and reproduce data from position P1 to P11, the data from position P12 to position P13, the data from position P14 to position P15 etc.Among the period T3 from time t2 to time t3, the amount of skipping is SK23, and obtains successively and reproduce data from position P2 to P21, the data from position P22 to position P23, the data from position P24 to position P25 etc.Among the period T4 from time t3 to time t4, the amount of skipping is SK24, and obtains successively and reproduce data from position P3 to position P31, the data from position P32 to position P33, the data from position P34 to position P35 etc.
Not it should be noted that and must reproduce, reproduce necessary amount and can only reproduce the realization speed change by all data in the scope of value a appointment.
In this way, under the situation of using table, even when coded system is not CBR mode but VBR mode, no matter the complexity of content is how, promptly no matter how transmit bit rate, also can be so that the time interval is realized the speed change reproduction more accurately.Can be according to the complexity of the image in each scene, by increasing the data volume that will skip in the scene that for example wherein has a large amount of complicated images, the time interval of controlling the image that will skip is set to the value of substantial constant.
Also can during special reproduction, specify mobile destination (amount of skipping) by the time (frame number).This can make the demonstration of image always have constant interval in time.Yet, no problem when the coded system of flow data is the CBR mode, and if wherein adopt the VBR mode, data volume changes with the complexity of picture, and it skips the position of destination therefore to be difficult to fast detecting.It is contemplated that if the detection of position postpones, then content may not can (under the situation of worst, depends on the traffic on the Internet 11) and arrives receiving system 12 in the speed change reproduction period.In this case, lose the data that receive in the centre, and can't realize smooth special reproduction.
On the contrary, as in the present embodiment, if be provided with by data volume, promptly in the amount of skipping of the content of speed change reproduction period, if the length of skipping is provided with by data volume (amount of bytes) rather than by the time (frame number), but then fast detecting to the address of skipping the destination.Therefore, though when the n value the in ± doubly fast F.F. of n greater than 3 the time, also can realize stable special reproduction.
In addition, can also use the part GET that only allows partly to obtain a part of resource.Therefore, if because the mistake that takes place and successfully do not obtain resource, then can begin to send resource from the part that success and then obtains in connecting the way, they are whole and do not need to resend.Especially, under the situation of present embodiment (wherein, data send or receive via the communication path that can not guarantee to provide reliable connection (such as the Internet)), this finally makes content be sent apace or receive.Therefore, can realize stable special reproduction.
In above stated specification, flow data and metadata are to provide from public server.Yet they can be to provide from different servers.
