Description
Technical Field
The invention relates to the technical field of display, in particular to a method, a device and a system for transmitting and receiving three-dimensional content.
Background
Before the advent of three-dimensional display technology, people typically played various content on display devices that had only two-dimensional display capabilities. Even if some of these contents are already three-dimensional contents (such as three-dimensional space digital model) or at least have partial three-dimensional information (such as computer graphic windows or graphic layers overlapped with each other), the three-dimensional image cannot be reproduced. With the advent of three-dimensional display technology, it is possible to reproduce content being played back by a three-dimensional display device as long as it carries three-dimensional information of a displayed scene or object in some way. For example, a stereo (stereoscopic) display device is a television set of model HX920 of sony corporation in japan, and an auto-stereo (auto-stereoscopic) display terminal is a BDL5231V three-dimensional display device of Dimenco corporation in the netherlands.
The three-dimensional content refers to content carrying three-dimensional information of a displayed scene or objects therein, in other words, the content carries at least three-dimensional spatial information, such as three-dimensional coordinate information, related to a part of the displayed scene or objects, and thus a three-dimensional spatial mutual position relationship within the scene or between the objects is established — relative to a viewer, the objects have not only a vertical, horizontal, positional relationship, but also an intuitive distance relationship. Accordingly, so-called two-dimensional content does not have such three-dimensional spatial information.
Currently, a stereoscopic display device represented by sony, etc. may play three-dimensional content in a side-by-side format, i.e., simultaneously have two images of the same scene, representing pictures that can be viewed by the left and right eyes, respectively, wherein the three-dimensional information is represented by the difference (Delta) between the two needle images. In addition, there is another content format named two-dimensional plus depth (2D plus depth), that is, a two-dimensional image of a scene and a depth map (depth map) matching the image and reflecting the spatial relationship of the scene are provided, wherein the three-dimensional information is represented by the depth map. The depth is a term that is substantially an alternative to the Z axis of the third coordinate axis in three-dimensional space, and can represent not only a positional relationship in which an object is far from a viewer with respect to a physical screen (in a reference plane having a reference meaning) of the display device, but also a positional relationship in which the object is close to the viewer. This two-dimensional depth-added content format allows for the playback of three-dimensional display effects on the Dimenco corporation autostereoscopic displays.
In fact, for better three-dimensional performance, more complex three-dimensional content formats, possibly a combination of two-dimensional deepening formats and side-by-side formats, are visible on some experimental three-dimensional display devices, and more than two side-by-side images may be simultaneously available for the same scene.
Additional display effects require additional data information. Obviously, no matter which format is adopted, three-dimensional content inevitably increases the amount of data significantly relative to two-dimensional content, and there is a trend toward further increase in such additional data. On the one hand, these three-dimensional information data occupy considerable transmission resources which are valuable for any network. As mentioned above, not all display devices can play three-dimensional contents, and if a content provider transmits three-dimensional contents to a non-specific display terminal, the three-dimensional contents unnecessarily occupy a large amount of bandwidth resources when the display devices do not support the three-dimensional contents or a user does not wish to view the three-dimensional contents at that time.
On the other hand, these added three-dimensional information have additional, added value, which is extraordinarily valuable relative to two-dimensional content. If the content provider sends three-dimensional content to a non-specific display device, the three-dimensional information may be unnecessarily sent to an unauthorized display device, thereby destroying the value of the three-dimensional information and damaging the interests of the three-dimensional information stakeholders.
Therefore, it is necessary to perform innovative processing on the transmission and reception of the three-dimensional information, thereby saving network resources and protecting added value brought by the three-dimensional information.

Please refer to the network system shown in fig. 1. The content provider 100 is connected to the two-dimensional display terminal 200, the first three-dimensional display terminal 300, the second three-dimensional display terminal 300', and the third three-dimensional display terminal 300 ″, respectively. For convenience of description, when referring to technical features common to the above two-dimensional display terminal 200, the first three-dimensional display terminal 300, the second three-dimensional display terminal 300', and the third three-dimensional display terminal 300 ″, these devices are collectively referred to as a display terminal.
Referring to fig. 2, the content provider 100 includes a content server 101, and three-dimensional content is stored in the content server 101 in the form of two-dimensional content plus three-dimensional information, such as depth information. In addition, the content providing terminal 100 further includes an authentication server 102 and an address server 103, wherein the authentication server 102 authenticates each display terminal according to an authentication rule REG and transmits address information ADD of the display terminal whose authentication result meets a specific requirement to the address server 103 and stores in a three-dimensional content transmission target sequence SEQ of the address server 103. The content provider 100 transmits three-dimensional content including two-dimensional content plus depth information to a display terminal in accordance with the three-dimensional content transmission target sequence SEQ, and transmits two-dimensional content to other display terminals.
Fig. 3 further illustrates the content form of two-dimensional content plus depth information. A three-dimensional content frame F with depth information comprises a first sub-frame L and a second sub-frame R, wherein each pixel on the first sub-frame L records color information and is finally combined into a 2D picture comprising two objects Obj1, Obj2 placed in front of a background Bac. The second sub-frame R is a depth table, corresponding to each pixel of the first sub-frame L, and each pixel on the second sub-frame R records a value between 0 and 255 for indicating the distance from the first sub-frame pixel to the viewer. In the three-dimensional content frame cited in the present embodiment, the depths of the background Bac, the two objects Obj1, Obj2 are Dep0, Dep1, and Dep2, respectively.
Referring to fig. 4, the two-dimensional display terminal 200 is based on the prior art and has a display module 201, a playing module 204 and an interface module 206 connected in sequence, wherein the interface module 206 is connected to the content provider 100 via a network and receives content, and the content received by the playing module 204 is then reproduced into a two-dimensional display effect via the display module 201.
The first, second and third three- dimensional display terminals 300, 300', 300 "comprise the same components and are only exemplarily described below with respect to the first three-dimensional display terminal. Referring to fig. 5, the first three-dimensional display terminal 300 includes a display module 301, a lens 302, a rendering module 303, a playing module 304, an editable identification module 305, and an interface module 306, wherein the lens 302 is attached to a display surface of the display module 301, the rendering module 303 is connected to an input end of the display module 301, the playing module 304 is connected to the rendering module 303, and the playing module 304 is further connected to the interface module 306 together with the identification module 305. Further, the identification module 305 may be edited, which stores therein the type identification: it may be the first identifier I1 representing the reception of three-dimensional content or the second identifier I0 representing the reception of two-dimensional content. The interface module 306 is connected to the content provider 100 through a network and receives content transmitted from the content provider 100. The play module 304 decodes the received content into a continuous sequence of frames, and for three-dimensional content, the play module 304 further matches the sequence of frames of two-dimensional content in the three-dimensional content with the sequence of depth information. The rendering module 303 renders the three-dimensional content of the two-dimensional content plus the depth information to generate pixel control information of the display module 301, the display module 301 controls the display of each pixel thereon according to the rendering result, and the three-dimensional display effect is presented through the refraction of the lens 302. The interface module 306 or the combination of the interface module 306 and the identification module 305 may be implemented independently in a set-top box or may be integrated with other components. The first three-dimensional display terminal 300 further has a flag setting editing module 307 which can set the editing flag module 305 to set the type flag stored in the flag module 305 to the first flag I1 or the second flag I0.
Referring to fig. 6, based on the content provider 100 and the display terminal, the present invention provides a method for transmitting three-dimensional content at the content provider 200, which may specifically include the following steps.
601. Acquiring a type identifier of a display terminal;
602. identifying the acquired type identifier of the display terminal;
603. and sending the content of the corresponding type to the display terminal according to the identification result.
In steps 601 and 602, please refer to fig. 6A, in order to send and receive content, a content transmission connection needs to be established between the content provider 100 and the display terminal. The display terminal sends a connection establishment request R1 containing its address information ADD to the content provider 100, and the content provider 100 replies an authentication request R2 to the display terminal. At this time, the two-dimensional display terminal 200 without the identification module 305 cannot interpret the authentication request R2, and replies an error prompt ERR or replies a Null message Null (no reply); the first three-dimensional display terminal 300 receives the authentication request R2, replies a message carrying the first identifier I1 to the content provider 100, and finally the content provider 100 replies a request confirmation RA to the display terminal, and a content transmission connection is established. In the process, if the type identifier is the first identifier I1, the content provider stores the address information of the display terminal in the three-dimensional content transmission target sequence of the content provider, and the content provider subsequently transmits the three-dimensional content to the display terminal corresponding to the address information in the three-dimensional content transmission target sequence. If the type identifier is the second identifier I0, the content provider may store the address information of the display terminal in the secondary three-dimensional content transmission destination sequence of the content provider, and the content provider subsequently transmits the two-dimensional content and the three-dimensional information of the specific part of the screen to the display terminal corresponding to the address information in the secondary three-dimensional content transmission destination sequence, or the content provider may transmit only the two-dimensional content to the display terminal. And if the ERR is prompted by a reply error or the Null message Null is replied (no reply) is received, the content providing end only sends the two-dimensional content to the display terminal.
Corresponding to the above-mentioned content transmission and reception process, the authentication server 102 of the content provider 100 may specifically include: a receiving unit, for receiving a connection establishment request R1 of the display terminal, wherein the connection establishment request R1 includes address information ADD of the display terminal; an authentication request transmitting unit for transmitting an authentication request R2 to the display terminal after receiving the connection establishment request R1; and the identification unit is used for determining that the display terminal supports receiving the three-dimensional content carrying the three-dimensional information and sending the address information ADD of the display terminal to the address server 103 if receiving the first identifier I1 sent by the display terminal, or determining that the display terminal supports receiving the two-dimensional content if receiving the second identifier I0 sent by the display terminal, receiving an error reply of the display terminal to the identification request, or not receiving a reply of the display terminal to the identification request R2.
Referring to fig. 6B, in order to speed up the connection establishment, the three- dimensional display terminal 300, 300', 300 ″ may also send the address information and the type identifier I1, I0 to the content provider 100 directly in the connection establishment request R1 without waiting for the authentication request R2 of the content provider. The content provider 100 replies a request confirmation RA to the display terminal and the content transmission connection is established.
Corresponding to the above-mentioned content transmission and reception process, the authentication server 102 of the content provider 100 may specifically include: a receiving unit, for receiving a connection establishment request R1 of a display terminal, wherein the connection establishment request R1 includes address information ADD of the display terminal; and the identification unit is used for determining that the display terminal supports receiving the three-dimensional content carrying the three-dimensional information and sending the address information ADD to the address server 103 if the connection establishment request further comprises the type identifier of the display terminal and the type identifier is the first identifier I1, or determining that the display terminal supports receiving the two-dimensional content if the connection establishment request does not comprise the type identifier of the display terminal or the type identifier is the second identifier I0.
The present embodiment does not require authentication of the display terminal every time a content transmission connection is established, and the content provider 100 can transmit the three-dimensional content based on the existing three-dimensional content transmission target sequence SEQ and perform authentication whenever it desires that there is a network connection. This example is only one of the preferred protocols for performing the identification.
In step 603, specifically, according to the identification rule REG, the display terminal providing the first identifier I1 will enter the three-dimensional content transmission target sequence SEQ through identification, and the error prompt ERR will not enter the three-dimensional content transmission target sequence SEQ either without returning Null or returning to the second identifier I0. Thus, the first three-dimensional display terminal 300 enters the three-dimensional content transmission target sequence SEQ, and the two-dimensional display terminal 200 does not. The content provider 100 transmits the three-dimensional content with the two-dimensional content plus depth information to the first three-dimensional display terminal 300 according to the three-dimensional content transmission target sequence SEQ, and accordingly, the content provider 100 transmits only the two-dimensional content to the two-dimensional display terminal 200.
Further, taking the second three-dimensional display terminal 300 'as an example, the value in the identification module 305 of the second three-dimensional display terminal 300' is set as the second identification I0 through the identification edit setting module 307. In the present embodiment, such setting may be made because the user of the second three-dimensional display terminal 300' is unwilling to watch the three-dimensional display effect again due to fatigue or other reasons. The user triggers the logo edit setting module 307 of the display terminal to set the value in the logo module 305 from the first logo I1 to the second logo I0 using the display terminal remote controller or the operation buttons of the display terminal. According to the authentication rule REG, the second three-dimensional display terminal 300 'will not enter (if necessary, be moved out of) the three-dimensional content transmission target sequence SEQ, and the content provider 100 will transmit only the two-dimensional content to the second three-dimensional display terminal 300'. Of course, if the subsequent second three-dimensional display terminal 300 ' sets the second identifier I0 as the first identifier I1 again, the content provider 100 will store the address information ADD of the second three-dimensional display terminal 300 ' in the three-dimensional content transmission target sequence SEQ according to the type identifier updated according to the setting according to the rule REG, and transmit the three-dimensional content to the second three-dimensional display terminal 300 '.
Further, as shown in fig. 2, the content provider 100 further has an identity setting server 104. Taking the third three-dimensional display terminal 300 "as an example, the identification module 305 of the third three-dimensional display terminal 300" is set as the second identification I0 by the identification setting server 104. In the present embodiment, such setting occurs because the user of the third three-dimensional display terminal 300 ″ cannot view a three-dimensional effect having an additional value because of no payment or other reasons, but can view only a two-dimensional effect having a general value. According to the rule REG, the third three-dimensional display terminal 300 "will not enter (if necessary, be moved out of) the three-dimensional content transmission target sequence SEQ, and the content provider 100 will transmit the two-dimensional content to the third three-dimensional display terminal 300". Of course, if the subsequent content provider 100 sets the type identifier of the third three-dimensional display terminal 300 "from the second identifier I0 to the first identifier I1 through the identifier setting server 104, the content provider 100 stores the address information of the third three-dimensional display terminal 300" in the three-dimensional content transmission target sequence SEQ according to the updated type identifier and transmits the three-dimensional content to the third three-dimensional display terminal 300 "according to the rule REG.
Further, taking the second three-dimensional display terminal 300 'and the third three-dimensional display terminal 300 ″ as an example, and referring to fig. 2B, when the type identifier is set to the second identifier I0, the content providing terminal 100 may still transmit the three-dimensional information Dep1 of the specific screen portion Obj1, preferably the content producer flag, the content sender flag, or the three-dimensional content order button, and the second three-dimensional display terminal 300' and the third three-dimensional display terminal 300 ″ may receive and display the three-dimensional content of the specific portion of the screen. Specifically, the depth information Dep1 of the picture-specific portion Obj1, preferably a static depth picture (frame), may be exclusively stored on the content server 101 of the content provider 100, and the address server 103 additionally has a secondary three-dimensional content transmission target sequence SEQ'.
