High-definition video conference system adopting Zhongtong satellite network

Abstract

The invention discloses a high-definition video conference system adopting a Zhongtong satellite network. The high-definition video conference system comprises a satellite ground station, a movable Zhongtong emergency satellite communication vehicle and a static Zhongtong emergency satellite communication vehicle, the satellite ground station comprises a satellite communication system, an Ethernetswitch, a video module, a voice module and a data module, a movable Zhongtong satellite antenna module, a satellite MODEM, the Ethernet switch, a VOIP voice gateway, a teleconference terminal, a vehicle-mounted phone, a vehicle-mounted indoor / outdoor camera, a display screen, a wireless single pawn video transmission system and a camera are installed in the movable Zhongtong emergency satellite communication vehicle. When the high-definition video conference system is in use, fast two-way broadband satellite link access can be achieved, an SCPC satellite channel is established, and dynamic image, voice and data transmission are achieved; and dynamic and static image, voice and data transmission are achieved, multiple communication modes coexist, multi-channel dynamic communication is provided for emergency command, and the system bandwidth resources are saved.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a high-definition video conferencing system using a Zhongtong satellite network. Background technique [0002] Satellite communication, simply put, is the use of artificial satellites as relay stations to forward or reflect radio waves between radio communication stations on the earth (including the ground, water surface and lower atmosphere), so as to realize communication between two or more earth stations a means of communication. It is a wireless communication method that can carry a variety of communication services, and is one of the important communication means in today's society. The satellite high-definition video conferencing system is an important part of satellite communication. [0003] For dynamic or static voice, data and video collection, the satellite ground station establishes an SCPC communication link to realize voice, data and video transmission wit...
