VIDEO ENCODING AND DECODING METHOD AND DEVICE AND VIDEO PROCESSING SYSTEM

摘要

A video encoding and decoding method and device and video processing system are provided. In the encoding method and device, ordinate and abscissa position information of each block in the searching area is established by selecting an appropriate origin of coordinates of the searching area; the offset of the current macro block is encoded simultaneously by using the information of the peripheral blocks of the current encoding macro block as the context for encoding the position offset information of the corresponding macro block in the adjacent view reference image of the current macro block so that the encoding efficiency is increased. In the decoding method and device, the position information of the corresponding macro block in the coordinate system is obtained by analyzing the offset information of the corresponding macro block of the current macro block so that the decoding efficiency is increased. The video processing system includes the video encoding device and the video decoding device with the above functions.
