Abstract

The present invention provides a HEVC inter-frame encoding processing method. The HEVC inter-frame encoding processing method is configured to speed up the decision speed of a skipping mode and improve the HEVC encoding efficiency. In the feasible embodiments of the invention, the method comprises: obtaining the predicted value and the original value of a current prediction unit (PU); calculating the error sum of squares of the predicted value and the original value of the PU; and comparing the error sum of squares and a threshold, and determining whether the prediction mode of the PU is the skipping mode or not according to the comparison result. The embodiment of the invention further provides a corresponding device.

Description

technical field [0001] The present invention relates to the technical field of video coding, in particular to an HEVC inter-frame coding processing method and device. Background technique [0002] High Efficiency Video Coding (HEVC) is the next generation of new video compression standards, and its goal is to improve the video compression efficiency by more than 30% compared with the existing H.264 / AVC (Advanced Video Coding, advanced video coding) High Profile (high-end specification), to use To replace the H.264 / AVC coding standard. [0003] CU (CodingUnit, coding unit) is the most basic unit of HEVC inter-frame and intra-frame coding. The size can be 64×64, 32×32, 16×16 and 8×8, and the unit is pixel. Each CU can be divided into multiple PUs (PredictionUnit, prediction unit). PU is the basic unit for intra-frame prediction and inter-frame prediction, and its size can range from 4×4 to 64×64. The shape of PU can be a block such as 4×4, or a rectangular block such as 4×8,...
