Abstract

The invention relates to a multi-channel video parallel display method for sky-ground network video communication. The method comprises the following steps: a, enabling ground equipment to receive video data sent from a spacecraft through a sky-ground integrated network; b, parsing the video data to obtain IP packet data; c, extracting application layer data in the IP packet data; d, reconstituting and packaging the application layer data to new IP packet data; and e, sending the new IP packet data to a player. The video parallel display method disclosed by the invention is low in developmentcost and small in development risk, supports remote tests, and has the characteristics of flexibly configuring software and supporting the replacement of hardware platforms.

Description

technical field [0001] The invention relates to the field of video monitoring, in particular to a multi-channel video parallel display method for video communication in the sky-earth network. Background technique [0002] With the increase of space-ground communication bandwidth and the improvement of standardization requirements, the space-ground video communication standard has gradually developed to multi-channel parallel communication, the video transmission medium is realized through the space-ground integrated network, and the video algorithm tends to adopt the standard H.264 video algorithm conversion. [0003] At present, there are two main solutions for video surveillance: one is dedicated video equipment method, which realizes video codec and playback functions through the development of special hardware boards; the other is based on commercial computer platforms, running video codec standards Library to implement video playback functionality. At present, the seco...
