Embodiment Construction
[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.
[0033] In order for people to understand the technical scheme of the present invention, the theoretical basis of the present invention is described below:
[0034] At present, the video in the digital TV broadcasting (DVB) transmission code stream is compressed by MPEG encoding. Since MPEG-2 encoding is mainly used in the digital TV system, the following uses MPEG-2 video stream as an example to illustrate.
[0035] see figure 1 , in order to facilitate bit error processing, random search and editing, the MPEG-2 code stream layer structure is as follows figure 1 As shown, the MPEG-2 video stream is mainly divided into a video sequence layer (VSL-Video SequenceLayer), a picture group layer (GOPL-Group of Pictures Layer), and a picture layer ...
