Embodiment Construction

[0083] figure 1 It is a flowchart of an embodiment of the video encoding processing method of the present invention, such as figure 1 As shown, the execution subject of this embodiment is the encoding end, then the method includes:

[0084] Step 101. Obtain the motion vector of the adjacent image block corresponding to the currently encoded image block, and obtain the first motion vector of the forward first reference frame of the current frame where the currently encoded image block is located according to the motion vector of the adjacent image block; The first motion vector is used to point to the first reference block in the first reference frame.

[0085] In this embodiment, the adjacent image block may be an adjacent image block in the spatial domain, or may be an adjacent image block in the temporal domain.

[0086] Step 102: Scale the first motion vector according to the i-th distance between the forward i-th reference frame of the current frame and the current frame...

Abstract

The invention provides a video encoding and decoding processing method and a video encoding and decoding processing device. The video encoding processing method comprises the following steps of: acquiring a motion vector of an adjacent image block corresponding to a currently encoded image block and according to the motion vector of the adjacent image block, acquiring a first motion vector of a forward first reference frame of a current frame in which the currently encoded image block is positioned; according to an ith distance between a forward ith reference frame of the current frame and the current frame and a first distance between the first reference frame and the current frame, carrying out zooming processing on the first motion vector and acquiring an ith motion vector of the ith reference frame; repeating the steps until an Nth motion vector of a forward Nth reference frame of the current frame is acquired; according to a reference block which each motion vector points at, acquiring a reference block of the currently encoded image block; and according to the reference block of the currently encoded image block, carrying out encoding processing on the currently encoded image block.

Description

technical field [0001] The present invention relates to communication technology, in particular to a video coding and decoding processing method and device. Background technique [0002] In video coding and decoding, the block-matching-based motion complement hybrid coding strategy usually mainly includes: prediction, transformation, quantization and entropy coding. The prediction mainly includes inter-frame predictive coding and intra-frame predictive coding, and the coding efficiency of inter-frame predictive coding is higher than that of intra-frame predictive coding. [0003] For inter-frame predictive coding, it is mainly used to eliminate the temporal redundancy of the video sequence. The specific processing process is mainly as follows: when the encoding end encodes a certain image block in the current image, all reference frames of the image block A search is performed in each reference frame, a prediction block corresponding to the image block is obtained in each r...
