Embodiment 1

[0063] like figure 1 As shown, when a point-to-point conference is in progress, one of the two terminals (such as the first terminal, also referred to as the calling terminal) that participates in the conference to conduct a conversation calls the other terminal (such as the second terminal, also referred to as the called terminal) in advance. ). After the call is successful and the conference is established, the two terminals can be used as the speaking terminal or the audience terminal. In the case of dual-stream audio, correspondingly another terminal is used as the audience terminal to receive the dual-stream audio, and the speaking terminal and the audience terminal can be interchanged during the conference.

[0064] exist figure 1 Among them, when the first terminal supports the SIP protocol and the H.323 protocol, and the second terminal only supports the H.323 protocol, the second terminal only supports the SIP protocol, or the second terminal supports the SIP protoc...

Embodiment 2

[0073] like image 3 As shown, when conducting a multipoint conference, the multipoint control unit (MCU) pre-calls multiple terminals participating in the conference. After the call is successful and the conference is established, each terminal can be used as a speaking terminal or an audience terminal. The audio from one endpoint is then forwarded to another endpoint or endpoints that act as the audience, and the speaker and audience can be interchanged during the conference.

[0074] because image 3 Dual-stream audio can be transmitted between the first terminal, the second terminal, and the MCU. This embodiment provides a method for sharing dual-stream audio in a multi-protocol compatible conference, such as Figure 4 As shown, the method is applied for example to image 3 The multi-point control unit MCU in, this MCU supports SIP agreement and H.323 agreement, comprises the following steps:

[0075] Step S20, respectively judge the protocol types supported by the firs...

Embodiment 3

[0091] Corresponding to Example 1, Image 6 Shows a structural block diagram of the device for sharing dual-stream audio in a multi-protocol compatible conference in Embodiment 3, which is applicable to the situation of point-to-point conferences, such as Image 6 As shown, the device is applied to the first terminal supporting the SIP protocol and the H.323 protocol, including:

[0092] The first calling unit 10 is configured to call the second terminal using the SIP protocol.

[0093] The first judging unit 11 is configured to judge whether the connection is successful according to the first response message returned by the second terminal.

[0094] The second calling unit 12 is configured to use the H.323 protocol to call the second terminal when the first judging unit judges that the connection is unsuccessful according to the first response message.

[0095] The second judging unit 13 is configured to judge whether the connection is successful according to the second re...

Abstract

The invention discloses a multi-protocol compatible method of sharing double stream audios in a conference, an apparatus and a system. One method is applied to a first terminal supporting a SIP protocol and an H.323 protocol and comprises the following steps of using the SIP protocol to call a second terminal; according to a first response message returned by the second terminal, determining whether connection is successful; when the connection is determined to be unsuccessful based on the first response message, using the H.323 protocol to call the second terminal; according to a second response message returned by the second terminal, determining whether the connection is successful; when the connection is determined to be successful based on the second response message, establishing a conference with the second terminal through the H.323 protocol, carrying out audio mixing on a single channel or multiple channels of mainstream audios and auxiliary stream audios and sending the audios after audio mixing to the second terminal through a mainstream channel. By using the method, the apparatus and the system of the invention, the double stream audios can be effectively shared in a video conference system of SIP and H.323 double protocols.

Description

technical field [0001] The present invention relates to the technical field of multimedia communication, in particular to a method, device and system for sharing dual-stream audio in a multi-protocol compatible conference, especially a method for sharing dual-stream audio in a SIP and H.323 dual-protocol video conferencing system , devices and systems. Background technique [0002] In the current video conferencing system, for dual-stream audio, if the protocols used by the video conferencing terminals are different when they join the conference, for example, one terminal adopts the SIP protocol and the other terminal adopts the H.323 protocol, the two terminals using different protocols They cannot communicate with each other, cannot transmit dual-stream audio to each other, and do not support dual-stream audio. [0003] An existing solution is to implement support for dual-stream audio by extending the non-standard dual-stream protocol, but when these terminals using the ...
