Abstract

The invention discloses a video compression transmission system based on satellite transmission, and the system specifically comprises the following parts: a receiving module, an analysis module, a storage module, a subpackaging module, a compression module, a packaging module, an analysis module, and a display module. The video occupation space can be reduced under the condition that the main body information is not reduced, through difference comparison of each frame of image of the video information, main body information and background information segmentation can be accurately and rapidly carried out on the image, thereby facilitating subpackaging and compression processing in subsequent steps; the background image is subjected to subpackage management, so that compression of the background image is facilitated, and meanwhile, in the satellite transmission process, subpackage management can improve the transmission efficiency and reduce the transmission time; each frame of image is compressed, so that the compression rate of each frame of image is greatly improved; and meanwhile, the main body image is not compressed, so that the main body information of each frame of obtained image is complete.

Description

technical field [0001] The invention relates to the fields of computers and intelligent computing, in particular to a video compression transmission system based on satellite transmission. Background technique [0002] With the development of science and technology, video information has become the most widely used information transmission method in the world, and the current video transmission methods mainly include wired transmission, wireless broadband transmission, GPRS / CDMA wireless communication technology and satellite transmission. Compared with other transmission methods, satellite transmission has the advantages of wide coverage, good communication quality, and not limited by geographical conditions, but its high transmission cost affects the wide application of industries. [0003] The paper "Satellite Communication Video Transmission Technology" published by Guo Xiaoxuan was published in "Digital Communication World" in 2018. This paper elaborates on the video tr...
