Title: VIDEO DATA REDUNDANCY CONTROL METHOD AND APPARATUS
Abstract:
Disclosed in the present invention are a video data redundancy control method and apparatus. The method comprises: acquiring a video code rate and redundancy level fed back by a receiving end, the video code rate and the redundancy level being determined by the receiving end on the basis of the packet loss rate; on the basis of the redundancy level, acquiring a data redundancy rate; implementing compression encoding of the source video data according to the video code rate to obtain compressed video data; on the basis of the video code rate and the data redundancy rate, allocating a frame-level redundancy code rate budget for the frames of the compressed video data; implementing sub-packaging of the frames of the compressed video data according to the frame-level redundancy code rate budget, and implementing redundancy encoding of the sub-packaged frames of the compressed video data.
