Abstract:
A request is received to play compressed video data in a reverse direction. A process identifies a most recent key frame received and decodes the most recent key frame. The process then identifies delta frames received after the most recent key frame and decodes these identified delta frames. The decoded delta frames are then played in the reverse direction. Additionally, compressed audio data can be decoded and played in the reverse direction along with the video data.
