Embodiment Construction

[0050] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0051] Most of the current mainstream embedded devices can only encode 2K high-definition video with a resolution of 1920x1080. In the field of audio and video, 4K ultra-high-definition video with a resolution of 3840×2160 is exactly four times that of 2K high-definition video with a resolution of 1920×1080, which belongs to ultra-high-definition resolution. At this resolution, viewers will be able to see every detail and every close-up in the picture clearly. If the astonishing 3840×2160 resolution is adopted, the audience can clearly see every detail of the picture no matter where they watch it. It is an indescribable enjoyment.

[0052]However, if the CPU of a high-performance x86 computer is used to process video compression...

Abstract

The embodiment of the invention provides a coding method and a coding system for an embedded device-oriented 4K ultra-high-definition video. The method comprises the following steps that: an embedded device segments the 4K ultra-high-definition video into a plurality of paths of 2K high-definition videos; the embedded device codes each path of the 2K high-definition videos; the embedded device carries out code stream-level synthesis on each of the coded 2K high-definition videos. The coding method and the coding system provided by the embodiment of the invention are used for lowering cost and CPU power consumption, and have the characteristics of real-time performance, stability and the like.

Description

technical field [0001] The present invention relates to the field of video technology, in particular to a coding method for 4K ultra-high-definition video oriented to embedded devices and a coding system for 4K ultra-high-definition video oriented to embedded devices. Background technique [0002] As users have higher and higher requirements for video clarity, the promotion of ultra-high-definition video with a resolution of 4K is an inevitable trend in the development of video technology in the future. However, in order to promote 4K ultra-high-definition video, it is necessary to solve the encoding problem of 4K ultra-high-definition video. At present, there are two main methods for encoding 4K ultra-high-definition video. One method is to use a high-performance x86 computer to utilize its powerful CPU performance to encode 4K ultra-high-definition video, but it has poor real-time performance and stability. And the problem of high power consumption. Another method is to ...
