Embodiment approach

[0053] 1. Capability negotiation and open logical channel method 1, Figure 8 It is the first method of capability negotiation and opening logical channel according to the embodiment of the present invention, such as Figure 8 As shown, this method includes the following steps:

[0054] Step S802, establishing a call between two telepresence endpoints;

[0055] Step S804, the two parties send the basic capability set through the existing H.245 message, and carry information for creating a new signaling channel; wherein, the information for creating a new signaling channel includes the adopted transmission protocol, IP address, port No;

[0056] Step S806, after the two parties complete the basic capability negotiation, open the logical channel of the basic capability based on the negotiation result;

[0057] Step S808, based on the information of the above-mentioned new signaling channel, establish a bidirectional new signaling channel for transferring characteristic parame...

Abstract

The present invention provides a capability negotiation processing method, device, and endpoint. The method includes: performing basic capability negotiation through the terminal capability set message of the endpoint, wherein the endpoint is based on the ITU‑T based packet switching The end point of the telepresence system of the H.323 protocol of the multimedia communication system of the network; the secondary capability negotiation of the telepresence feature of the end point is carried out in a predetermined way, and the present invention solves the problems existing in the related art without changing the current protocol , the problem of negotiating the new feature parameters of the telepresence system cannot be realized, and then the effect of realizing the negotiation of the new feature parameters of the telepresence system on the basis of not changing the existing protocol is achieved.

Description

technical field [0001] The present invention relates to the communication field, in particular to a capability negotiation processing method, device and telepresence endpoint. Background technique [0002] At present, in the video conferencing technology based on the ITU-T multimedia communication system based on the packet switching network (referred to as H.323), when using the ITU-T multimedia communication control protocol (referred to as H.245) for capability set negotiation, only The basic capabilities of codec can be negotiated, but the newly added scene description, media collection source description, encoding group description, and multi-stream description of the telepresence system cannot be negotiated. For example, the description of multiple collection combinations from the same conference site, and the combination information of multiple streams from the sender for selection by the receiver cannot be completed through the existing H.245 capability negotiation p...
