Abstract

The invention provides an image parallel coding method and an image parallel coding system. The image parallel coding method comprises the steps of dividing a to-be-coded image into a plurality of coding areas, wherein each coding area corresponds to a coding unit line in an image coder, and each coding unit line comprises a plurality of coding units; and starting the plurality of coding unit lines to carry parallel coding on the plurality of coding areas in sequence according to a preset starting relationship. Through application of the technical scheme of the invention, the relatively high compression efficiency can be ensured, the image coding speed can be effectively improved, and the user experience can be improved.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a picture parallel coding method and a picture parallel coding system. Background technique [0002] With the development of information technology, the status of pictures in information display is becoming more and more important. The volume of a picture in a web page is several times that of all the text in it. Obviously, the larger the picture size, the more time users load the web page. The longer it takes. [0003] HEVC (High Efficiency Video Coding) is the latest video coding standard. Compared with the previous generation standard H.264 / AVC (Advanced Video Coding, Advanced Video Coding), its compression rate can be improved by one Times, can adapt to a wide range of application requirements. HEVC can also be applied to image coding, and can bring about a 25% increase in compression efficiency. However, the coding complexity also increases according...
