Abstract
A rotation-based multiple description video coding and decoding method, apparatus and system. The coding method comprises the following steps: extracting one frame f in a video sequence; carrying out symmetric transformation on the frame f, and then performing H.264 coding to obtain a description 1; and directly performing H.264 coding on the original frame f to obtain a description 2. The present invention also provides a redundancy adjustment coding method and a corresponding decoding apparatus and system. The method, apparatus and system of the present invention can be used for signal coding and decoding of multimedia information in an environment where error codes occur frequently.
