1. A satellite communication video narrow-band communication system comprises video equipment, a heat exchanger, high-definition video compression equipment (code streams with the high resolution of 1080P are compressed from 8Mbps to 500kbps or below), a satellite modem, a ground or shipborne satellite antenna and a satellite; the method is characterized in that: high-definition video compression equipment (the code stream with the high-definition 1080P is compressed from 8Mbps to 500kbps and below) is connected to a satellite modem through a heat exchanger; when video sent by video equipment enters a heat exchanger, high-power compression processing is carried out on the video by the high-definition video compression equipment, a video code stream is subjected to high-power compression and then enters a satellite modem through the heat exchanger, and the video code stream is transmitted to a ground or ship-borne satellite antenna through the satellite modem and is transmitted to a satellite through the satellite antenna; the video is downloaded via satellite communication.

Technical Field

The invention relates to a satellite communication video communication system, in particular to a satellite communication video narrowband communication system.

Background

The existing satellite communication video communication system is convenient to use, but is limited by the bandwidth and technology of the existing satellite communication ground facility, so that the cost is high, and the popularization is difficult.

Disclosure of Invention

The invention overcomes the defects in the existing satellite communication video communication system and provides a satellite communication video narrow-band communication system; high-definition video compression equipment (a code stream of high-definition 1080P is compressed from 8Mbps to 500kbps and below) is connected to a satellite modem through a heat exchanger; when video sent by video equipment enters a heat exchanger, high-power compression processing is carried out on the video by the high-definition video compression equipment, a video code stream is subjected to high-power compression and then enters a satellite modem through the heat exchanger, and the video code stream is transmitted to a ground or ship-borne satellite antenna through the satellite modem and is transmitted to a satellite through the satellite antenna; the video is downloaded via satellite communication.

The invention is solved by the following scheme: high-definition video compression equipment (a code stream of high-definition 1080P is compressed from 8Mbps to 500kbps and below) is connected to a satellite modem through a heat exchanger; when video sent by video equipment enters a heat exchanger, high-power compression processing is carried out on the video by the high-definition video compression equipment, a video code stream is subjected to high-power compression and then enters a satellite modem through the heat exchanger, and the video code stream is transmitted to a ground or ship-borne satellite antenna through the satellite modem and is transmitted to a satellite through the satellite antenna; the video is downloaded via satellite communication.

The invention has the beneficial effects that: saving bandwidth and having remarkable benefit.

1. And bandwidth is saved. The satellite communication video narrowband communication system adopts high-definition video compression equipment (the code stream of high-definition 1080P is compressed from 8Mbps to 500kbps or less), so that narrowband transmission is realized, and the satellite communication bandwidth is greatly saved.

2. The benefit is remarkable. The satellite communication video narrow-band communication system saves satellite communication video communication cost by times, and obviously generates social benefit and economic benefit.
