Some embodiments of the invention, by the field syntax elements encoded implication of extension standards protocol definition, are conducive to realize an encoding and decoding more flexibly.

For example, picture structure (picture_structure) indicating bit: when present image is horizontally interlaced image, indication present image is with row-by-row system coding or interlace mode coding.

For example, can represent that two field picture data occur successively when the value of picture_structure indicating bit is 0, present image is encoded with interlace mode, first coding or decoding one field picture data another field picture data of encoding or decode; The two field picture data blending that can represent present image when picture_structure indicating bit value is 1 occurs,, present image is encoded or is decoded with row-by-row system, and when encoding or decoding, deliberately not distinguishing two field picture data is top field picture data or end field picture data.

For example can expand the implication of progressive_frame indicating bit.Wherein, in standard agreement, progressive_frame indicating bit is only used to indicate a frame of video and comprises progressive scanning picture data or comprise horizontally interlaced image data.The indication implication of some embodiments of the invention expansion progressive_frame indicating bit, for example, progressive_frame indicating bit comprises progressive scanning picture data or comprises horizontally interlaced image data except a frame of video in can instruction video code stream, can also indicate when frame of video comprises single game view data, indicate top field picture data or end field picture data that this single game view data is image.

Wherein, progressive_frame indicating bit specific definition for example can be as follows:

For example, when the value of progressive_frame indicating bit is 0, the two field picture data that can instruction video frame comprise are for from field picture data in the same time not, and image is horizontally interlaced image.Now this frame of video can take that row-by-row system carries out coding/decoding (if picture_structure indicating bit value is 1) or the interlace mode of can take is carried out coding/decoding (picture_structure indicating bit value is 0).

When the value of progressive_frame indicating bit is 1, two field picture data blending that can indicating image occurs, be that present image is encoded or decoded with row-by-row system, when encoding or decoding, deliberately the two field picture data of differentiate between images are not top field picture data or end field picture data.Now, this frame of video is carried out coding/decoding with row-by-row system.

When the value of progressive_frame indicating bit is 2, can comprise single game view data and not comprise two field picture data by instruction video frame, and the single game view data that this frame of video comprises is top field picture data.

When the value of progressive_frame indicating bit is 3, can comprise single game view data and not comprise two field picture data by instruction video frame, and the single game view data that this frame of video comprises is end field picture data.

Wherein, in the expansion of above-mentioned progressive_frame indicating bit, when progressive_frame indicating bit value 2 or 3, a frame of video comprises single game view data and does not comprise two field picture data, therefore now without carry out the code encoding/decoding mode of the two field picture data in instruction video frame by picture_structure indicating bit, therefore, now the value of picture_structure indicating bit is made as fixed value, as can be fixedly made as 1 or 0.

Can find out, by the implication of extension syntax element progressive_frame indicating bit, be conducive to effectively support a frame of video to encode separately in single game mode, thus the complexity to coded data management and reference frame management while being conducive to simplify coding on the scene.

In addition implication that also can extension syntax element top_field_first indicating bit, the sequencing that top_field_first indicating bit can be used for indicating the homology frame of video of a frame of video and this frame of video to occur in video code flow.The specific definition of top_field_first indicating bit for example can be as follows:

For example, when the value of top_field_first indicating bit is 1, can indicate the top field picture data in this field picture data correspondence image prior to end field picture data, to occur in video code flow, be that the sequencing that the homology frame of video of frame of video and this frame of video occurs in video code flow is that the frame of video that comprises end field picture data homology frame of video (frame of video that comprises top field picture data) prior to this frame of video in video code flow occurs.

For example, when the value of top_field_first indicating bit is 0, after can indicating top field picture data in this field picture data correspondence image in video code flow, in end field picture data, occur, be that the rear order that the homology frame of video of frame of video and this frame of video occurs in video code flow is that the frame of video that comprises top field picture data homology frame of video (frame of video that comprises end field picture data) prior to this frame of video in video code flow occurs.

Wherein, by the indication implication of extension syntax element top_field_first indicating bit, be conducive to video decoder and clearly know how each field picture data and the opposite field view data of decode output blend to obtain the image that blends.Wherein, top_field_first indicating bit can seen a kind of specific implementation of the second indication parameter in above-described embodiment.

First in conjunction with video encoding/decoding method, give an example below.

Suppose, the decoded video frame in video code flow is decoded, after decoding, the field picture data sequence of output is as follows successively: bot1, top2, bot3, top4, bot5 ...

Wherein, bot represents that end field picture data, top represent top field picture data.Wherein, numbering below of bot and top (1,2,3,4,5 ...) represent output order after code stream decoding.2 (the value of the progressive_frame indicating bit of the decoded video frame in video code flow is, decoded video frame comprises single game view data and this single game view data is top field picture data) or 3 (that is, decoded video frame comprise single game view data and this single game view data is end field picture data).And the value of the top_field_first indicating bit of all coded frame is 1.In the present example, because the value of the top_field_first indicating bit of all coded frame is 1, therefore, in code stream, in image corresponding to all field picture data, be all that top field picture data occur prior to end field picture data in video code flow.Therefore, known according to above-mentioned code flow structure, bot1 occurred before top2, because the top field picture data of syntactic element top_field_first indicating bit indicating image occur in video code flow prior to top, field, end field picture data all the time, therefore, bot1 cannot blend into a width blending image at video decoder with top2, after bot3, in top2, in code stream, occur, and the rear output order of the decoding of bot3 and top2 is adjacent, therefore, top2 can be blended into piece image with bot3, in like manner, top4 blends into piece image with bot5.Other can be by that analogy.

In like manner, the value of supposing the top_field_first indicating bit of all decoded video frames in above-mentioned code flow structure is 0, and video decoder can blend into piece image with top2 by bot1, in like manner, bot3 can be blended into piece image with top4.Other can be by that analogy.

In addition the anti-error code capacity of video decoder in the time of, can also increasing field coding according to the combination of progressive_frame and top_field_first syntactic element.

Suppose, the decoded video frame in video code flow is decoded, after decoding, the field picture data sequence of output is as follows successively: bot1, top2, top3, bot4, bot5 ...2 (the value of the progressive_frame indicating bit of the decoded video frame in video code flow is, decoded video frame comprises single game view data and this single game view data is top field picture data) or 3 (that is, decoded video frame comprise single game view data and this single game view data is end field picture data).Different from previous example, the value of the top_field_first indicating bit that decoded video frame is corresponding is not quite similar, bot1 for example, top2, top3, bot4, bot5 ... the value of corresponding top_field_first indicating bit is as follows successively: 0,0,1,1,1 ...

Wherein, because the value of bot1 and top_field_first indicating bit corresponding to top2 is 0, therefore in image corresponding to these two field picture data, be that top field picture data occur in end field picture data after in video code flow, therefore, video decoder can blend into piece image with top2 by bot1.Because the value of top3 and top_field_first indicating bit corresponding to bot4 is 1, therefore, in image corresponding to these two field picture data, be that top field picture data occur prior to end field picture data in video code flow, video decoder can blend into piece image with bot4 by top3.Other can be by that analogy.Now can think that missing image or error of transmission do not occur this section of video code flow.

Hypothesis, decodes to the decoded video frame in video code flow again, and after decoding, the field picture data sequence of output is as follows successively: bot1, top2, top3, bot4, bot5 ...The value of the progressive_frame indicating bit of the decoded video frame in video code flow is 2 or 3.Wherein, the value of the top_field_first indicating bit that decoded video frame is corresponding is not quite similar, bot1 for example, top2, top3, bot4, top5 ... the value of corresponding top_field_first indicating bit is as follows successively: 0,0,0,1,1 ...

Because the value of bot1 and top_field_first indicating bit corresponding to top2 is 0, therefore in image corresponding to these two field picture data, be that top field picture data occur in end field picture data after in video code flow, so video decoder can blend into piece image with top2 by bot1.Because the value of top_field_first indicating bit corresponding to top3 is 0, therefore, in image corresponding to this this single game view data, be that top field picture data occur in end field picture data after in video code flow, and before top3, be next-door neighbour's top2, because piece image can not comprise two top field picture data, can know by inference thus, between top2 and top3, lost field picture data at the bottom of a width, or in transmitting procedure, there is error code and make some top_field_first indicating bits and/or progressive_frame indicating bit mistake in video code flow.The value of the syntactic elements such as the progressive_frame indicating bit that video decoder comprises according to decoded video frame in video code flow and top_field_first indicating bit, judge after frame losing or error condition appear in video video code flow, can how to process frame losing or error condition according to setting strategy decision.

Simply introduce the video-frequency compression method to video coding apparatus below.Video-frequency compression method can comprise compression and interframe compression in frame, and video coding apparatus is the interframe compression methods that adopt based on estimation now more.For example, video coding apparatus adopts interframe compression method can comprise the process of image compression coding: video coding apparatus is divided into several equal-sized subimage blocks by image block to be encoded, then for each subimage block, the image block that search is mated with current subimage block most in reference picture is as prediction piece, then this subimage block is subtracted each other and obtains residual error with the respective pixel values of prediction piece, the value that this residual error is obtained after conversion and quantification is carried out entropy coding, the coded data codings such as the bit stream finally entropy coding being obtained and motion vector information.Accordingly, first video decoder obtains and carries out entropy decoding after entropy coded bit stream and obtain the coded datas such as corresponding residual error and corresponding motion vector information; Then according to motion vector information, in reference picture, obtain corresponding matching image piece (being above-mentioned prediction piece), then be added according to the value of corresponding pixel points in the value of each pixel in matching image piece and residual values the value that obtains each pixel in current subimage block.Infra-frame prediction refers to that the information of utilizing in this width image predicts and obtain predicting piece image block, video coding apparatus obtains according to predictive mode, prediction direction, current image block pixel value around the pixel of predicting that piece is corresponding, current image block pixel is subtracted each other and obtained residual error with prediction piece pixel, and residual error writes in code stream after conversion, quantification and entropy coding; Video decoder is resolved code stream, code stream is carried out obtaining residual block after entropy decoding, inverse quantization, inverse transformation, video decoder obtains predicting piece according to predictive mode, prediction direction and image block pixel value around, and residual block pixel and prediction piece pixel addition are obtained to reconstructed image piece.

Inter prediction encoding is mainly used for eliminating video sequence redundancy in time, its concrete processing procedure mainly comprises: during some image blocks in video coding apparatus coding present image, in all reference frames of this image block, search for, in each reference frame, obtain respectively a prediction piece corresponding with this image block, and according to get one group of prediction piece to the processing of encoding of this image block.In order to improve the efficiency of inter prediction encoding, inter prediction image can also be further subdivided into predicted picture between forward frame, the P frame being commonly called as in video coding and decoding technology, and bidirectional interframe predictive image, the B frame being commonly called as in video coding and decoding technology.Wherein, preceding paragraph inter prediction image is used currently treats that the image before encoding and decoding image carries out coding-decoding operation, bidirectional interframe predictive image use current treat encoding and decoding image before and image afterwards carry out coding-decoding operation.Because bidirectional interframe predictive image need to be used, currently treat that the image after encoding and decoding image carries out coding-decoding operation, before treating encoding and decoding bidirectional interframe predictive image, need the image after this bidirectional interframe predictive image of first encoding and decoding.

Because bidirectional interframe predictive image has been used present image coded message before and afterwards, bidirectional interframe predictive image can improve code efficiency than predicted picture between forward frame.In order further to improve the code efficiency of bidirectional interframe predictive image, hierarchical B frame (Hierarchical B) technology is applied to the encoding and decoding of bidirectional interframe predictive image.Wherein, in level B frame technique, bidirectional interframe predictive image also can be used as reference picture and uses.The B frame of different levels has different priority, and the B frame that priority is high can be used as the reference frame of the B frame that priority is low.The priority of above-mentioned B frame can be by some syntactic elements for sign.
