6th step：Roi_pic_flag marks are set to 0, are encoded by HEVC standard method；
Subsequently, when marked interesting target image is extracted in the code stream from mark, extraction flow is as follows：
The first step：The interesting target logos position roi_pic_flag in slice heads is parsed, if the flag bit is 1,
Into second step, otherwise into the 3rd step；
Second step：The syntax elements roi_pic_idx of interesting target image object category label is parsed, judges the category
Whether number roi_pic_idx occurs first, if it is, directly extracting the frame code stream, is stored in new image object category label
ASCII stream file ASCII, otherwise into the 3rd step；
3rd step：It is stored in the ASCII stream file ASCII of the correspondence image object type label of extraction；
4th step：The frame is skipped, into next frame.
By such scheme, the frame of video of matched indicia (for example is assisted by design object label in Video coding
Increase corresponding syntax elements in view), and the mode such as encoding frame type (I frames) so that the frame of video of matched indicia can be made
Extracted for independently decodable subcode stream, improve the fluency of video playback, meet user's request.
