Abstract

An HEVC inter-frame coding processing method is used to speed up the judgment speed of the skip mode and improve HEVC coding efficiency. In some feasible implementations of the present invention, the method includes: obtaining the predicted value and original value of the current prediction unit PU; calculating the error sum of squares between the predicted value and the original value of the PU; comparing the error sum with a threshold Comparing, judging whether the prediction mode of the PU is a skip mode according to the comparison result. The embodiment of the present invention also 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 a new next-generation video compression standard, and its goal is to improve video compression efficiency compared to the existing H.264 / AVC (Advanced Video Coding, Advanced Video Coding) High Profile (high-end specification) More than 30%, used to replace the H.264 / AVC coding standard. [0003] CU (Coding Unit, 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, and so on. [...
