Problems solved by technology
This method uses two grammatical elements and introduces two intermediate variables. The rules for exporting the display order of video images are more complicated, and the parsing of image headers is also more complicated.

Embodiment Construction
[0032] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0033] The present invention provides a method for representing the display order of video images, including an encoding step and a decoding step, wherein,
[0034] Such as figure 1 As shown, the encoding steps include:
[0035] Step S11, determining the encoding order and decoding order of each frame of video images in the video sequence, wherein the decoding order and encoding order are the same;
[0036] Step S12, determining the display order of each frame of video images in the video sequence;
[0037] Step S13, calculate the display delay of each frame of video image according to the encoding sequence and display sequence of the frame of video image, wherein the display delay is the delay required from decoding a certain f...

The invention provides a video image display sequence representing method. The video image display sequence representing method includes coding and encoding. Coding includes the steps that the coding sequence and display sequence of each frame of video image in a video sequence are determined; display delay is calculated according to the coding sequence and display sequence of each frame of video image; the display delay is taken as one part of coding data of the frame of video image; coding data of all video images are arrayed according to the coding sequence to form a coded video sequence. Decoding includes the steps that coding data of each frame of video image in the coded video sequence are decoded according to the decoding sequence to acquire each frame of video image and the display delay of the frame of video image; the display sequence of each frame of video image is calculated according to the decoding sequence and display delay of each frame of video image; each frame of video image is displayed according to the display sequence of the video images. The video image display sequence can be more easily and conveniently derived according to the method.
Description
technical field [0001] The invention relates to a method for representing the display sequence of video images. Background technique [0002] A video sequence is composed of a series of images that change over time, and there is redundancy between video images. In order to remove the redundancy between video images, you can refer to the encoded video images when encoding some video images, which is called interframe predictive coding. If only the previously coded video image in time is referred to when coding a frame of video image, it is called forward predictive coding, and this frame of video image is called a P frame. If when encoding a frame of video image, it refers to both the encoded video image in the front in time and the encoded video image in the back in time, it is called bidirectional predictive coding, and the video image in this frame is called a B frame . When bidirectional predictive coding is used, it is necessary to encode some temporally behind video ...
