    Abstract: A method, an apparatus and a system for a rapid motion search applied in template matching are disclosed. The method includes: selecting motion vectors of blocks related to a current block as candidate motion vectors of the current block; after the uniqueness of a series of the candidate motion vectors of the current block is maintained, calculating the cost function of the candidate motion vectors in a corresponding template area of a reference frame, and obtaining the motion vector of the best matching template from the candidate motion vectors of the current block. In the embodiments of the present invention, there is no need to determine a large search range and no need to determine the corresponding search path template, and it is only necessary to perform a search in a smaller range.

    Abstract: 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.
