Abstract

An embodiment of the invention provides a method, a device and a system in-frame predictive coding and encoding. The method includes the steps of acquiring the most probable mode (MPM) set of a current block and in-frame predicting mode utilized in the current block, wherein elements in the MPM set are acquired from an in-frame predicting mode of a block adjacent to the current block t; determining information of the in-frame predicting mode utilized by the current block according to the number of elements and the evaluation of the MPM set; and sending code stream including the information of the in-frame predicting mode of the current block to a decoding device. When in coding the in-frame predicting mode of the current block, the number of the elements and the evaluation of the MPM set can be fully considered, by aiming at different number of the elements and evaluations, a coding device is capable of selecting corresponding codes to code the in-frame predicting mode of the current block, so that the coding mode is more flexible.

Description

technical field [0001] Embodiments of the present invention relate to video image encoding and decoding technologies, and in particular, to an intra-frame prediction encoding and decoding processing method, device and system. Background technique [0002] In order to reduce the resources occupied during video signal storage or transmission, the video signal is compressed at the sending end and then transmitted to the receiving end, and the receiving end restores the video signal through decompression processing and plays it. The sender or receiver here can be a mobile phone, digital phone terminal, wireless device, personal data assistant (PDA), hand-held or portable computer, GPS receiver / navigator, camera, audio / video player, video camera, video recorder , monitoring equipment, etc. [0003] In existing video image encoding and decoding technologies, in order to improve the encoding efficiency of I frames, both H.264 and Advanced Video Coding (Advanced Video Coding, AVC f...
