Example Embodiment
[0071] The present invention will be further described below in conjunction with the description of the drawings and the specific embodiments.
[0072] The AVS-P2 video sequence starts from the sequence header, followed by one or more encoded images, and the sequence end code indicates the end of a video sequence. The first coded picture after the sequence header should be an I frame. An image is a frame, and its encoded data starts from the image start code and ends with the sequence start code, sequence end code or the next image start code. These bits should not appear in any case except the start code string. The start code is composed of the start code prefix and the start code value. The start code prefix is the bit string ‘0000 0000 0000 0000 0000 0001’. All start codes should be byte aligned. The start code value is an 8-bit integer used to indicate the type of start code.
[0073] In the present invention, the RTP header is not extended, so the bit X=0 in the RTP fix...
