Abstract: The present disclosure provides a forward multiple-hypothesis encoding/decoding method of an image block. In this method, motion information of a current block including two forward reference frame indexes and two motion vectors are selectively encoded into a bit-stream based on a current encoding mode. The motion information which is not encoded into the bit-stream is derived at a decoder by a predefined rule. This method sufficiently utilizes correlation within motion information of an image block and correlation between the motion information of the current image block and that of an adjacent image block.

Abstract translation: 本公开提供了图像块的前向多重假设编码/解码方法。 在该方法中，基于当前编码模式，将包括两个前向参考帧索引和两个运动矢量的当前块的运动信息选择性地编码为比特流。 未被编码到比特流中的运动信息在解码器处被预定义的规则导出。 该方法充分利用图像块的运动信息内的相关性和当前图像块的运动信息与相邻图像块的运动信息之间的相关性。
