As shown in Figure 2, be a kind of schematic flow sheet of setting up the method for local video library of another embodiment of the present invention, can be as described below.
201, the input keyword is retrieved in the EPG content in the EPG searcher.
The user imports correspondent keyword according to oneself hobby and focus in the EPG searcher, can specify in then in some or several channels and search for, and as at central one and central four, also can search in all channels; Simultaneously, can also specify is to search in the EPG content how long, as one day, and seven days etc., thus guarantee that Search Results is consistent as far as possible with user expectation.
202, master chip generates the ordering of priority by certain algorithm deterministic retrieval result and priority, according to how many generations of local storage availability resource intends the tabulation of program recording simultaneously.
Master chip according to the hunting zone of the keyword of user input and appointment (for example, in the EPG content in those channels several days, search for), utilize certain algorithm to determine the priority of program in the Search Results, and determine the ordering of program according to the height of priority, generate the ordering of priority and intend the tabulation of program recording.The priority of program is mainly by following one or more factors decision: the reproduction time of the position that keyword occurs (for example, occurring in the program names in the still brief introduction), program, program whether existences in local memory device, program duration, whether determine with factors such as the reproduction time of the higher program of priority conflict mutually.
According to Search Results, the size of considering the local memory device free space generates the plan program recording inventory of pressing the reproduction time ordering automatically simultaneously, and store in the program storage device, thereby the user is come into plain view to wanting recorded program, guarantee to want recorded program to record on time.
203, can be by EPG searcher change program priority, to guarantee that the TV programme of paying close attention to is in time recorded and, to generate the tabulation of intending program recording automatically according to the size of local memory device free space.
Consider that the keyword that the user imports might not be very accurate, therefore what the medium priority as a result that comes out of search was the highest might not be that the user wants recorded program, so provide the user can revise the authority of program priority, the user can revise program priority at Search Results by the EPG searcher, and can directly specify and record that program, other and user want the automatic conductively-closed of the afoul program of recorded program to fall, just intending the program recording inventory can upgrade automatically according to the situation of user's modification program priority, guarantee to intend the real-time of program recording inventory information, thereby make the user can accurately understand recorded program content.
For fear of change owing to the playing programs time, causing missing the phenomenon of recording appointed program takes place, the keyword search situation is carried out associative operation in step 201,202,203 at regular intervals automatically again, and upgrades in time according to the result and to intend the program recording inventory.
204, arrived the reproduction time of intending program recording, set-top box is waken up from standby mode, records the module recording TV program and stores local memory device into.
Record module then according to what of local storage resources, according to priority order is from high to low recorded the TV programme that searches in large quantity.
Finish after the operation of 201,202,203 steps, the user just can allow set-top box enter holding state, at this moment, the master chip of set-top box etc. enters low power consumpting state, can cut off the power supply of local memory device simultaneously, Overall Power Consumption can be lower than 1W, thereby effectively reduces the power consumption of set-top box when waiting for performance recording.When having arrived the described operation of the reproduction time of intending program recording or execution in step 201,202,203, set-top box is activation automatically, and restores electricity to various piece, guarantees that program normally records and upgrade.
Idle function under ideal case, can turn-off the power supply of local memory device, but it's time to be scheduled to want recorded program to begin to play, start automatically, and to the local memory device power supply, thereby realize normal recording function.
Record module then according to what of local storage resources, according to priority order is from high to low recorded the TV programme that searches in large quantity and is stored local memory device into, master chip stores the recorded content classification into local memory device simultaneously according to certain classification.
Whether for example, master chip is to the selection of recorded content, can want downloaded contents and hard disk can utilize the size in space to determine the actual program of recording those contents according to existing in the height of the degree of correlation in the Search Results and the local memory device.
For example, news is recorded mode, the set-top box that is used for PVR generally all has time-shifting function, so when the keyword of certain user's setting occurring, as " aircraft ", the content of the certain time length automatically this program front play of master chip is recorded so, thereby the program of recording the certain time length of keyword after occurring simultaneously guarantees the integrality of record news message, and the concrete time can be set.
Can set those programs by the EPG searcher must record, if set, when the local memory device space is not enough, for example, when the local memory device space is lower than certain threshold value, master chip is disposed the file that conforms to a predetermined condition, and for example master chip can be disposed the file that certain sets frequency of utilization that is less than that certain time point existed in the past in the enactment document folder automatically, thereby guarantees to want program recording normally to record.
In the performance recording process, the commercial breaks in the middle of master chip is discerned automatically is with its rejecting.
205, master chip is kept at the program recording classification in the local memory device, and master chip is set up the catalogue of preservation content to support the content search function of local program at program storage device.
For example, master chip is recorded the program that gets off with PVR, according to classification storages such as program classification such as news, TV play, film, variety, stores the recorded content classification into local memory device.Master chip is set up the catalogue of preserving content at program storage device simultaneously, to support the content search function of local program.。
Master chip manages recorded file, for example, master chip is recorded the program that gets off and is divided into different files according to each program according to recording module, (can be categorized as TV play, film, variety and news simultaneously, various big class file folders such as competitive sports) manage, the EPG searcher is supported the search locating function of recorded file, and master chip is set up the catalogue of preserving content at program storage device, thereby makes the user can find the program storage position of recording quickly and easily.
Being kept at the program of local memory device, is exactly the interested local video resources bank of customization, and whether the user can have up-to-date message in any thing that whether own real interested content is arranged and oneself pay close attention to of checking at odd times.
In another embodiment of the present invention, be that example describes for example with performer A.
For example, the film that the user acts the leading role performer A, TV play is interested, he just can import " performer A " two words by the EPG searcher in searching menu so, and the selection search for is " performer ", can be chosen in all channels, search (can certainly specify in some channels in all EPG information, search in the shorter EPG content of time, as the CCTV-6 movie channel, search in the EPG information in two days), specified to click behind the hunting zone to begin search and get final product, set-top box will search program according to definite priority algorithm automatically and sort from high to low according to priority.
The program Determination of priority is relevant with several factors, and principal element has:
1) position of search key appearance be to appear in programm name, the featured performer as keyword, or in the brief introduction, for example, it is the highest to appear at the programm name medium priority;
2) number of times that in program EPG information, occurs of search key, number of times is many more, and priority is high more;
3) the concrete reproduction time of program, the time, more early priority was high more;
4) Pgmtime length, program is short more, and priority is high more;
5) whether program exists in local memory device, and program exists in local memory device, then is zero, does not exist for 1;
6) whether exist the higher program of priority to conflict, the words program priority step-down of existence with this program reproduction time.
Master chip is by the above factor of consideration, and the proportion difference shared according to each factor, determines corresponding weight coefficient, and a kind of specific algorithm of priority is as follows:
A＝B×(C+D+E+F+G)
Whether wherein: on behalf of program, B exist in local memory device, and having B is zero, and not having B is 1; The position that on behalf of search key, C occur, keyword is programm name and featured performer, C is 0.3; In the EPG content, C is 0.2; D is the number of times that keyword occurs in program EPG information, and more than 3 times, D is 0.2, twice to be 0.1, once is 0.05; E is a playing programs time priority level coefficient, and the time, more early priority was high more, highest order 0.2; F is the program duration, and minimum is zero, is 0.1 to the maximum; Whether G for conflicts mutually with the higher program of priority, and conflict then is zero, and not conflicting is 0.2.
After master chip has been determined the priority of program, which will under the situation of considering the local memory device available size, can record by definite program, this is determined by program priority, recording module records from high to low according to program priority, the afoul TV programme of reproduction time that all reaches recording request for two priority wherein, then master chip compares the priority of these two programs, guarantees that the program of high priority is recorded, and abandons the program of low priority.Therefore the master chip inventory about the TV programme of performer A that can obtain recording, this inventory is tactic according to the playing programs time order and function, and this inventory is kept in the program storage device.In intending the program recording inventory, the user also can be by the hobby of EPG searcher according to oneself, revise the priority that some do not think recorded program, and, user's modification after the program priority, intending the program recording inventory can regenerate according to user's modification once, as will vanishing with the priority of the film of the performer A of 2 broadcasts this afternoon, thereby variation according to priority, can regenerate a program recording inventory of intending, at this moment, 2 pm just might appear in the plan program recording inventory with afoul other programs about performer A of film that the performer A that has revised priority acts the leading role.Thereby guarantee to record as much as possible the high as far as possible program of priority.
Just determined and to have recorded those programs that just can be kept at Search Results in the program storage device this moment by top step.
And the reproduction time by these programs, set the timer in the set-top box master chip, make it to automatically set-top box being waken up under holding state when intending the program recording reproduction time, record module and begin program recording thereby make.
After setting timer, master chip can be set at holding state with set-top box, to avoid set-top box also not working in the program recording, wastes energy.Simultaneously, the thing of wanting program recording of missing that causes for fear of the change owing to the TV programme reproduction time takes place, set the institute of set-top box above one hour repeats down automatically in steps,, guarantee to want recorded program in time to be recorded to understand the up-to-date variation in the program EPG information.
For recording the program that gets off, can be divided into different files according to each program, simultaneously can be categorized as TV play, film, variety and news, the convenient management of various big class file folder such as competitive sports, and support the local search function, the user can be by finding oneself most interested program easily in the multitude of video program of keyword search under record this locality.
