Embodiment Construction
[0088] The present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.
[0089] H.264 / AVC video is mainly composed of I frame, B frame and P frame images. Due to consideration of inter-frame drift and distortion, the selected embedded frame is P frame. A P frame image contains at least one P slice, and a P slice is composed of several P macroblocks and several I macroblocks. The coding mode of the P macroblock is divided into five types: SKIP, Inter_16×16, Inter_16×8, Inter_8×16, and P8×8. When the P macroblock is coded in the Inter_16×16 coding mode, the P macroblock is divided into one 16×16 motion sub-block; when the P macroblock is coded in the Inter_16×8 coding mode, the P macroblock is divided into 2 16×8 motion sub-blocks; when P macroblock adopts Inter_8×16 encoding mode for encoding, P macroblock is divided into two 8×16 motion sub-blocks; when P macroblock adopts P8×8 encoding mode for encoding , the P...
