Embodiment Construction

[0020] Such as figure 1 with figure 2 As shown, the satellite IP video conference system includes a central station and several remote stations. The central station has several modems. Each modem is connected to a port of the central station router. Each remote station is equipped with a modem, and One port of the remote station router is connected, the remote station is equipped with an IP video conference terminal, and the central station is equipped with an IP video conference terminal and a multipoint control unit.

[0021] A routing configuration method for a satellite IP video conference system includes the following steps:

[0022] (1) Choose a modem of the central station as the video multicast sending modem, set the sending carrier center frequency and sending rate, and turn on the carrier sending switch;

[0023] Configure an IP address on the port connecting the central station router and the video multicast sending modem, and start the pim dm multicast routing protocol ...

Abstract

The invention discloses a route allocation method of a satellite IP (Internet Protocol) video conference system and relates to the technical field of satellite communication. The method comprises the following steps: cooperatively utilizing a pim dm protocol and an igmp protocol to realize the multicast transmission from a central station to a remote station, and allocating main and auxiliary IP addresses at a router port of the remote station to realize the video multicast reception and video pass back on the basis of a single modem. The method disclosed by the invention is used for both realizing the multicast transmission from the central station to the remote station and supporting the video pass back from the remote station to the central station; the system has the advantages of saving the bandwidth and guaranteeing simple allocation, so that the method is especially suitable for the application of satellite communication systems creating video conferences.

Description

Technical field [0001] The invention discloses a routing configuration method of a satellite IP video conference system, which relates to the technical field of satellite communication. It is especially suitable for the use of satellite communication systems for video conferencing. Background technique [0002] Satellite communication has the advantages of wide coverage, strong broadcasting capability, and less restricted by geographical conditions. The satellite network as a supplement and backup of the ground network has received extensive attention at home and abroad, and the application of using satellite networks to form video conferences is becoming more and more common. [0003] The general satellite IP video conference system is equipped with video conference terminals in the remote station, and the central station is equipped with video conference terminals and multipoint control units. When a conference is set up, each remote station establishes a two-way point-to-point ...
