    • Inter-frame prediction coding method, device and system are provided. The inter-frame prediction coding method includes: calculating distortions between a template area of current encoding block and each of M matching templates in L reference frames, to determine M offset vectors; acquiring M hypothesis prediction values of the encoding block to which the M matching templates correspond according to the determined M offset vectors, and calculating the template matching prediction value of the current encoding block according to the M hypothesis prediction values; comparing the template matching prediction value and original value of the current encoding block to acquire the residual of the current encoding block, and encoding the residual. The technical solution improves prediction performance of the video coding system and increases coding efficiency.

    • A video encoding and decoding method and device and a video processing system are provided. In the encoding method and device, ordinate and abscissa position information of each block in a searching area is established by selecting an appropriate origin of coordinates of the searching area; meanwhile, an offset of a current macro block is encoded by using information of peripheral blocks of the macro block encoded currently as a context for encoding position offset information of a corresponding macro block in an adjacent view reference image of the current macro block. In the decoding method and device, position information of a corresponding macro block in a coordinate system is obtained by parsing offset information of the corresponding macro block of the current macro block, and motion information of the corresponding macro block is used as motion information of the current macro block. So the coding efficiency is increased.
    • 提供视频编码和解码方法和设备以及视频处理系统。 在编码方法和装置中,通过选择搜索区域的适当的坐标原点来建立搜索区域中每个块的纵坐标和横坐标位置信息; 同时,通过使用当前编码的宏块的外围块的信息作为当前宏块的相邻视图参考图像中的对应宏块的位置偏移信息的上下文来编码当前宏块的偏移量。 在解码方法和装置中,通过对当前宏块的相应宏块的偏移信息进行解析来获得坐标系中的相应宏块的位置信息,并且使用相应宏块的运动信息作为运动信息 当前宏块。 因此编码效率提高。
