摘要： Disclosed are a method for implementing telepresence technology and a telepresence device. The method comprises: a first telepresence device establishes a communication connection with a second telepresence device, wherein the first telepresence device performs a first capability negotiation with the second telepresence device during the communication connection establishment; the first telepresence device performs a TIP capability negotiation with the second telepresence device; the first telepresence device and the second telepresence device determine, according a result of the first capability negotiation and a result of the TIP capability negotiation, an audio and video coding/decoding mode used in the following communication; and the first telepresence device communicates with the second telepresence device according to the determined audio and video coding/decoding mode. The present invention solves a technical problem in the prior art that new audio and video coding/decoding modes cannot be used because content of a TIP protocol is not updated in time, thereby achieving a technical effect of improving the expansion capability of the telepresence technology.

摘要： A method and system for implementing large capacity calls by using the H.323 protocol stack are provided in the present invention. The method comprises: a plurality of protocol stacks are deployed in a multi-point control unit; an IP address of a third protocol stack is pre-configured as a uniform IP address of the multi-point control unit, wherein the IP address acts as an incoming address when the multi-point control unit is called, and the third protocol stack is used to perform the H.225 signaling interaction with the opposite end when the multi-point control unit is a called party; when the multi-point control unit is a calling party, a first protocol stack, the number of processable calls of which does not exceed a limit number, is selected to perform the H.225 signaling interaction with the opposite end, and a second protocol stack, the number of processable calls of which does not exceed a limit number, is selected to perform the H.245 signaling interaction with the opposite end; when the multi-point control unit is a called party, a fourth protocol stack, the number of processable calls of which does not exceed a limit number, is selected to perform the H.245 signaling interaction with the opposite end. In the present invention, the H.245 messages from different ends are distributed to a plurality of protocol stacks for processing, which thereby improves the processing efficiency.
