When progressive_frame indicating bits value be 2 when, can indicate frame of video include single game view data and Not comprising two field picture data, also, the single game view data that the frame of video includes is top field picture data.
When progressive_frame indicating bits value be 3 when, can indicate frame of video include single game view data and Not comprising two field picture data, also, the single game view data that the frame of video includes is bottom field picture data.
It is appreciated that because the progressive_frame indicating bits after extension implication have four kinds of possible values, Therefore progressive_frame indicating bits include at least two bits.Progressive_frame indicating bits can look at above-mentioned A kind of specific implementation of the first instruction parameter in embodiment.
Wherein, in the extension of above-mentioned progressive_frame indicating bits, when progressive_frame indicating bits A frame of video includes single game view data and does not include two field picture data during value 2 or 3, therefore need not now pass through Picture_structure indicating bits indicate the code encoding/decoding mode of the two field picture data in frame of video, therefore, now The value of picture_structure indicating bits is set to fixed value, can such as fix being set to 1 or 0.
As can be seen that by the implication of extension syntax element progressive_frame indicating bits, be advantageous to effectively support One frame of video is individually encoded in a manner of single game, to coded data management and reference during so as to be advantageous to simplify coding on the scene The complexity of frame management.

First illustrated below with reference to video encoding/decoding method.
It is assumed that being decoded to the decoded video frame in video code flow, the field picture data sequence exported after decoding is successively It is as follows：Bot1, top2, bot3, top4, bot5 ....
Wherein, bot represents that bottom field picture data, top represent top field picture data.Wherein, the numbering behind bot and top (i.e. 1,2,3,4,5 ...) output order after expression code stream decoding.The progressive_ of decoded video frame in video code flow The value of frame indicating bits is 2, and (that is, it be to push up field picture that decoded video frame, which includes single game view data and the single game view data, Data) or 3 (that is, it is bottom field picture data that decoded video frame, which includes single game view data and the single game view data).Also, institute The value for having the top_field_first indicating bits of coded frame is 1.In the present example, due to the top_ of all coded frames The value of field_first indicating bits is 1, therefore, in code stream in image corresponding to all field picture data be top field figure As data occur in video code flow prior to bottom field picture data.Therefore, it can be seen from above-mentioned code flow structure, bot1 top2 it Preceding appearance, because the top field picture data of syntactic element top_field_first indicating bits instruction image are all the time prior to Di Changding Field picture data occur in video code flow, and therefore, bot1 and top2 can not blend to blend into a width in video decoder to scheme Picture, bot3 occur after top2 in code stream, and after bot3 and top2 decoding output order it is adjacent, therefore, can by top2 with Bot3 blendings are into piece image, and similarly, top4 and bot5 blends into piece image.Other can be by that analogy.
Similarly, it is assumed that the value of the top_field_first indicating bits of all decoded video frames is in above-mentioned code flow structure 0, then video decoder bot1 and top2 can be blended into piece image, similarly, bot3 and top4 can be blended into a width figure Picture.Other can be by that analogy.
In addition, field can also be increased according to the combination of progressive_frame and top_field_first syntactic elements The anti-error code capacity of video decoder during coding.
It is assumed that being decoded to the decoded video frame in video code flow, the field picture data sequence exported after decoding is successively It is as follows：Bot1, top2, top3, bot4, bot5 ....The progressive_frame of decoded video frame in video code flow refers to The value for showing position is 2 (that is, decoded video frame includes single game view data and the single game view data is top field picture data) or 3 (that is, it is bottom field picture data that decoded video frame, which includes single game view data and the single game view data).It is different from previous example , the value of top_field_first indicating bits is not quite similar corresponding to decoded video frame, such as bot1, top2, top3, The value of the corresponding top_field_first indicating bits of bot4, bot5 ... is as follows successively：0,0,1,1,1 ....
Wherein, because the value of top_field_first indicating bits corresponding to bot1 and top2 is 0, therefore this two figures It is that top field picture data occur in video code flow after bottom field picture data in the image as corresponding to data, therefore, video solution Code device can blend bot1 and top2 into piece image.Due to top_field_first indicating bits corresponding to top3 and bot4 Value be 1, therefore, in image corresponding to this two field picture data be top field picture data in video code flow prior to bottom field figure As data appearance, video decoder can blend top3 and bot4 into piece image.Other can be by that analogy.It can now recognize Missing image or error of transmission does not occur for this section of video code flow.
Again it is assumed that decoded to the decoded video frame in video code flow, the field picture data sequence exported after decoding according to It is secondary as follows：Bot1, top2, top3, bot4, bot5 ....The progressive_frame of decoded video frame in video code flow The value of indicating bit is 2 or 3.Wherein, the value of top_field_first indicating bits is not quite similar corresponding to decoded video frame, The value of the corresponding top_field_first indicating bits of such as bot1, top2, top3, bot4, top5 ... is as follows successively：0, 0,0,1,1 ....
Because the value of top_field_first indicating bits corresponding to bot1 and top2 is 0, therefore this two field picture data It is that top field picture data occur in video code flow after bottom field picture data in corresponding image, therefore video decoder can Bot1 and top2 is blended into piece image.Because the value of top_field_first indicating bits corresponding to top3 is 0, therefore, It is that top field picture data occur in video code flow after bottom field picture data in image corresponding to this single game view data, and Be before top3 close to top2, because piece image can not possibly include two top field picture data, it is possible thereby to deduce, top2 A width bottom field picture data are lost between top3, or error code occurs in transmitting procedure and causes some top_ for video code flow Field_first indicating bits and/or progressive_frame instruction bit-errors.Video decoder is according in video code flow The syntactic elements such as progressive_frame indicating bits and top_field_first indicating bits that decoded video frame includes take Value, after judging that frame losing or error condition occurs in video video code stream, can according to setting strategy decision how to handle frame losing or Error condition.
It following is a brief introduction of to the video-frequency compression method of video coding apparatus.Video-frequency compression method may include frame internal pressure Contracting and interframe compression, video coding apparatus now more uses the interframe compression method based on estimation.For example, Video coding fills Put may include using interframe compression method to the process of compression of images and coding：Video coding apparatus divides image block to be encoded Into several equal-sized subimage blocks, then for each subimage block, search for and current subgraph in a reference image Then the respective pixel values of the subimage block and prediction block are subtracted each other to obtain residual error as prediction block by the image block that block most matches, By the transformed value progress entropy code with being obtained after quantifying of the residual error, the bit stream for finally obtaining entropy code and motion vector letter The coded datas such as breath coding.Accordingly, progress entropy decoding obtains accordingly after video decoder obtains entropy code bit stream first Residual error and the coded data such as corresponding motion vector information；Then obtained in a reference image according to motion vector information Corresponding matching image block (i.e. above-mentioned prediction block), picture is corresponded in the value and residual values of each pixel further according to matching in image block The value of vegetarian refreshments is added to obtain the value of each pixel in current subimage block.Infra-frame prediction refers to utilize the information pair in this view picture Image block is predicted to obtain prediction block, and video coding apparatus is according to the picture around predictive mode, prediction direction, current image block Element is worth to pixel corresponding to prediction block, subtracts each other to obtain residual error by current image block pixel and prediction block pixel, residual error is transformed, Quantify to write in code stream with after entropy code；Video decoder parses code stream, and entropy decoding, inverse quantization, inverse transformation are carried out to code stream After obtain residual block, video decoder is worth to prediction block according to the pixel around predictive mode, prediction direction and image block, Residual block pixel is added with prediction block pixel to obtain reconstructed image block.
Inter prediction encoding is mainly used for eliminating the redundancy of video sequence in time, and its concrete processing procedure is main Including：When video coding apparatus encodes some image block in present image, enter in all reference frames of the image block Row search, obtains a prediction block corresponding with the image block in each reference frame respectively, and according to one group got Prediction block carries out coded treatment to the image block.In order to improve the efficiency of inter prediction encoding, inter prediction image can also enter One step is subdivided into preceding to interframe prognostic chart picture, i.e., the P frames being commonly called as in video coding and decoding technology, and bidirectional interframe predictive image, The B frames being commonly called as in video coding and decoding technology.Wherein, preceding paragraph inter prediction image uses the figure before currently treating encoding and decoding image As carrying out coding-decoding operation, bidirectional interframe predictive image carries out volume solution using image before currently treating encoding and decoding image and afterwards Code operation.Because bidirectional interframe predictive image needs to use the current image treated after encoding and decoding image to carry out coding-decoding operation, Image after the first encoding and decoding bidirectional interframe predictive image is needed before treating encoding and decoding bidirectional interframe predictive image.
Because bidirectional interframe predictive image has used coding information before present image and afterwards, bidirectional interframe predictive figure As code efficiency can be improved compared to forward direction interframe prognostic chart picture.In order to further improve the coding of bidirectional interframe predictive image Efficiency, hierarchical B frame (Hierarchical B) technology are applied to the encoding and decoding of bidirectional interframe predictive image.Wherein, in level B frames In technology, bidirectional interframe predictive image can act also as reference picture use.The B frames of different levels have different priority, excellent The high B frames of first level can be low as priority B frames reference frame.The priority of above-mentioned B frames can be used for by some syntactic elements Mark.
