Embodiment Construction

[0033] The present invention is a method for transmitting real-time messages in a multimedia communication system, wherein the real-time information refers to information transmitted in real-time in the multimedia communication system in text, picture or other forms. The main difference between the present invention and the prior art is that the real-time message is transmitted through the signaling channel.

[0034] image 3 It is a schematic diagram of a specific embodiment of the real-time message transmission method of the present invention. The text message (such as "Hello") input by the user at the sending end is processed by the terminal device and delivered to the receiving end through the signaling channel, and the receiving end receives the message from the signaling channel. The data is then processed to output message information (ie "Hello"). For the H.320 system, the signaling channel can be a BAS (Bit Assignment Signaling) channel, and for the H.323 system, the...

Abstract

The real-time message transmitting method is used in multimedia communication system to transmit real-time message in signaling channel. The signaling message is expanded correspondingly and the real-time message is transmitted via the expanded signaling message simply. For multipoint service, the real-time message is transmitted via MCU or other transfer equipment in relatively low cost. Furthermore, the real-time message is well fused with video and audio service and may be superposed onto video image for output conveniently without using alone data meeting server. The real-time message maybe transmitted via H.245 control channel, etc., with the H.245 protocol being part of the H.323 protocol application. By means of solving the NAT problem and fire wall problem of H.323 protocol application, the problem of bi-directional penetration of real-time message in NAT equipment may be solved.

Description

technical field [0001] The invention relates to a message transmission method, in particular to a real-time message transmission method in a multimedia communication system. Background technique [0002] The development of multimedia applications on the existing narrowband and broadband networks has great commercial prospects. The video conferencing system is based on data communication, using the existing IP network to transmit real-time image information and voice information at the same time. Provides a convenient and fast way for people meeting at the same location. [0003] In addition to audio and video interactions, current multimedia applications sometimes need to exchange short real-time messages. For example, when using a video conferencing system for point-to-point communication or multipoint conferences, information can also be exchanged through real-time messages. [0004] Real-time messages mainly have the following functions: express accurate meaning through ...
