    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: The present disclosure discloses a method for determining a motion vector, comprising the steps of: determining at least one inter-layer reference block by referring to an inter-layer corresponding block of a current processing block; determining the motion vector(s) of the current processing block according to the motion vector(s) of the determined at least one inter-layer reference block as well as the motion vectors of the other adjacent blocks of the current processing block. In comparison with the prior art, in the present disclosure, when a motion vector of a current processing block is derived, the information of the inter-layer corresponding block is referred to and inter-layer correlation in a multi-layer video is utilized, thus compression and coding efficiency for a video are improved remarkably.
