Abstract

Embodiments of the present invention provide a reusable video encoding method and encoder. The reusable video coding method of the present invention includes: acquiring a frame of image; acquiring the processing sequence of the prediction unit for performing inter-frame prediction on the image according to preset inter-frame prediction parameters, the inter-frame prediction parameters including inter-frame prediction Mode, position of prediction unit, type of prediction unit, processing time control information of prediction unit, prediction effect comparison algorithm, next prediction jump information and end mark; Inter-frame prediction is performed on the position corresponding to the prediction unit, and the image is encoded according to the result of the inter-frame prediction. The embodiment of the present invention solves the problem that the PU selection algorithm is fixed and single. When the application scene changes and the PU type and processing sequence change, hardware changes must be made to adapt to the new scene, which is not conducive to the improvement and expansion of the encoding system performance.

Description

technical field [0001] The embodiments of the present invention relate to video compression technology, and in particular to a reusable video encoding method and encoder. Background technique [0002] In recent years, with the rapid development of information technology, people's requirements for the visual quality of video have been continuously improved, and the emergence of high-definition, ultra-high-definition and 3D videos has been widely favored by everyone. However, a 720P high-definition image takes up 2.2 megabytes (MByte, MB for short) storage space without compression. If the frame rate of a video is 30 frames per second, even if it is only five minutes, the amount of data will reach 19 gigabytes. Byte (GigaByte, referred to as GB), it can be seen that the amount of data occupied by high-quality video that meets people's needs is very large, and uncompressed original video data is unacceptable now and even in the future, whether it is storage or transmission. Th...
