Abstract: The application discloses video data redundancy control methods and apparatuses. Video packet redundancy control information is determined according to packet loss at a reception apparatus. The video packet redundancy control information is received from the reception apparatus. Video data is encoded according to the video packet redundancy control information to obtain encoded video data of a plurality of frames by a transmission apparatus. A frame-level redundancy budget is allocated for one of the plurality of frames according to the video packet redundancy control information. Further, the one of the plurality of frames is packetized according to the frame-level redundancy budget to generate a packetized frame. Redundancy coding is performed on the packetized frame to generate video packets including data packets and redundant packets for transmission to the reception apparatus.

Abstract: Video data processing method and apparatus are provided. The method includes: encoding, by an encoder side, obtained original video data according to a hierarchical P-frame prediction HPP structure to obtain an HPP bitstream; redundancy-coding the HPP bitstream according to a forward error correction FEC code, redundancy packet quantities in frames in the HPP bitstream progressively decreasing from lower to higher temporal layers to which the frames belong in the HPP structure; and sorting the frames in the redundancy-coded HPP bitstream and sequentially sending the frames in the redundancy-coded HPP bitstream to a decoder side.
