Band-width control method, apparatus, terminal and system based on video conference

Abstract

The embodiment of the invention provides a bandwidth controlling method, device, terminal and system based on videoconference; the method comprises the steps that: the conference control apparatus respectively establishes call connection with the circuit network terminal and packet switched network terminal; the conference control apparatus ensures that the packet switched network bandwidth does not satisfy the packet switched network video data transmission request and notifies the circuit network terminal to execute code stream controlling, thereby reducing the circuit network video data transmission speed. The technical proposal provided by the embodiment of the invention, when judging that the packet switched network bandwidth does not satisfy the packet switched network video data transmission request, notifies the circuit network terminal to execute code stream controlling, which solves the problem of losing packet in videoconference mixed by circuit network terminal and packet switched network, and stably reduces the speed in the videoconference mixed by circuit network terminal and packet switched network and strengthens the network suitability and improves the ease of use of mixed networking.

Description

technical field [0001] The present invention relates to video conferencing technology, in particular to bandwidth control technology in video conferencing, specifically a video conferencing-based bandwidth control method, device, terminal and system. Background technique [0002] The video conferencing system can be applied to a circuit switching network or a packet switching network, but there are many problems when the above two networks are used in combination, such as packet loss and bandwidth cannot be guaranteed. The general standard for video conferencing systems based on circuit networks is H.320, and the H.320 standard includes a series of standards to serve it, such as H.221 / H.242 / H.239, etc.; the general standard for video conferencing systems based on packet switching networks It is H.323, and the H.323 standard includes a series of standards to serve it, such as H.245 / Q.931 / H.239 and so on. [0003] For mixed applications of H.320 and H.323, the system needs to...
