Description

Method for video coding and video encoding/decoding method and relevant apparatus

Technical field

The present invention relates to technical field of image processing, be specifically related to method for video coding and video encoding/decoding method and relevant apparatus.

Background technology

Along with development and the ever-increasing high-definition digital video demand of photoelectric acquisition technology, the video data volume is increasing, transmission bandwidth, the diversified Video Applications of limited isomery constantly propose higher demand to video coding efficiency, the formulation work of high-performance video coding (HEVC, HighEfficientVideoCoding) standard is because needing to start.

The general principle of Video coding compression utilizes spatial domain, correlation between time domain and code word, removes redundancy as far as possible.Current popular way adopts block-based mixed video coding framework, realizes Video coding compression by the step such as prediction (comprising infra-frame prediction and inter prediction), conversion, quantification, entropy code.This coding framework, shows very strong vitality, and HEVC also still continues to use this block-based mixed video coding framework.

Time domain motion vector predictor (TMVP, TemporalMotionVectorprediction) technology is the motion vector (MV being applicable to haplopia/layer, MotionVector) Predicting Technique, utilizes the motion of time domain reference image (motion) information to predict the MV (motionvector) of current block.From multiple time domain reference image, determine the correspondence image (collocatedpicture) of 1 image as present image, utilize the MV of the motion information prediction present image of this correspondence image.

TMVP technology is applied to multi-video coding and decoding (MVC, multi-viewcoding) in, not substantially is looked to the Code And Decode of (non-baseview), except the motion information of multiple time domain reference images utilizing current non-baseview, also may utilize from the motion information of looking a reference picture substantially depending on (baseview), predict the MV of current block.Usually need from these multiple time domain reference images and this be depending on determining a reference picture that 1 image is as current non-baseview correspondence image.
