Embodiment Construction
[0037] According to the requirement of real-time interactive performance of multi-viewpoint video coding and the principle of distributed source coding, the present invention proposes a new multi-viewpoint video coding method. This method uses distributed source coding at the switching point when encoding each viewpoint video, while other frame encoding methods are the same as the frame encoding methods in the H.264 standard, and the codec principle of the SW frame Structural block diagram as shown in Figure 1 and Figure 2, wherein SW represents the video image to be encoded, B 1 is the motion vector coded bitstream, B 21 and B 22 is the check bit stream output by the channel encoder, where the channel encoder is code rate compatible, that is, the check information output by the channel encoder is scalable in code rate, B 3 is an inter-view displacement coded bitstream.
[0038] The multi-viewpoint video coding method that the present invention proposes, comprises the follo...
