Abstract

Embodiments of the present invention disclose a method, an apparatus, and a system for controlling a conference including a telepresence conference site, and relate to the field of network communications technologies. An embodiment of the present invention provides a method for controlling a conference site in a telepresence conference, including: receiving attribute information of a telepresence conference site sent by the telepresence conference site, where the telepresence conference site includes at least two video areas; and performing conference control according to the received attribute information of the telepresence conference site. Through application of the present invention, the conference control process of the telepresence conference site may be simplified.

First claim

What is claimed is:

1. A method for controlling a conference including a telepresence conference site and a plurality of additional conference sites, the method comprising:
receiving attribute information of the telepresence conference site sent by the telepresence conference site, wherein the telepresence conference site comprises at least two video areas; and
performing conference control according to the received attribute information of the telepresence conference site;
wherein the attribute information of the telepresence conference site comprises one or any combination of the following items: a type of a conference site, video area information of the conference site, a stream attribute corresponding to a video area of the conference site, a conference site terminal number corresponding to the video area of the conference site, the video area of the conference site, a corresponding relationship between a stream and a conference site terminal, a corresponding relationship between the video area and a stream of the conference site and telepresence conference site interworking, and a corresponding relationship between the video area and the stream of the local conference site and common conference site interworking;
wherein when the conference including the telepresence conference site needs to be performed between multipoint control units, the performing the conference control further comprises:
according to the received attribute information of the telepresence conference site, determining a number of cascade channels between cascaded multipoint control units; and
establishing the determined number of the cascade channels.

2. The method for controlling the conference including the telepresence conference site according to claim 1 , wherein the performing the conference control comprises:
storing the received attribute information of the telepresence conference site, as a basis of the conference control.

3. The method for controlling the conference including the telepresence conference site according to claim 1 , wherein the performing the conference control comprises:
identifying each of the conference sites according to the attribute information of each of the conference sites.

4. The method for controlling the conference including the telepresence conference site according to claim 1 , wherein the performing the conference control comprises:
delivering the attribute information of each of the plurality of additional conference sites to the telepresence conference site.

5. The method for controlling the conference including the telepresence conference site according to claim 1 , wherein when the stream information carried in the conference control request message is the stream information of the conference site controlled by one of the cascaded multipoint control units, the performing the corresponding stream processing according to the conference control request message comprises:
according to the conference control request message, sending an image switching request message carrying the stream information to the cascaded multipoint control unit; and
obtaining a corresponding stream of the cascaded multipoint control unit through one of the cascade channels.

6. The method for controlling the conference including the telepresence conference site according to claim 5 , wherein the step of performing the corresponding stream processing according to the conference control request message further comprises:
according to the conference control request message, resolving whether the obtained stream needs to be combined;
if the obtained stream needs to be combined, performing stream combination processing and delivering a combined stream after processing to the conference site that sent the request; and
if the obtained stream does not need to be combined, delivering the obtained stream to the conference site that sent the request.

7. The method for controlling the conference including the telepresence conference site according to claim 6 , wherein the image switching request message comprises at least a multi-channel image switching message between the cascaded multipoint control units, and
the multi-channel image switching message between the cascaded multipoint control units comprises at least one of the following items: a serial number of the cascade channel, a serial number of a switched conference site, a stream serial number of the switched conference site, and channel operation type information.

8. A multipoint control apparatus, comprising a processor and a non-transitory processor-readable medium having processor-executable instructions stored thereon, the processor-executable instructions including a plurality of modules, the modules including:
an information receiving module, configured to receive attribute information of a telepresence conference site sent by the telepresence conference site, wherein the first telepresence conference site comprises at least two video areas; and
a conference control module, configured to perform conference control according to the received attribute information of the telepresence conference site;
wherein the attribute information of the telepresence conference site comprises one or any combination of the following items: a type of a conference site, video area information of the conference site, a stream attribute corresponding to a video area of the conference site, a conference site terminal number corresponding to the video area of the conference site, the video area of the conference site, a corresponding relationship between a stream and a conference site terminal, a corresponding relationship between the video area and a stream of the conference site and telepresence conference site interworking, and a corresponding relationship between the video area and the stream of the local conference site and common conference site interworking;
wherein the conference control module further comprises: a cascade channel establishment submodule, configured to, according to the received attribute information of the telepresence conference site, determine a number of cascade channels between cascaded multipoint control units, and establish the number of the cascade channels, when a conference including the telepresence conference site needs to be performed between multipoint control units.

9. The multipoint control unit according to claim 8 , wherein the conference control module comprises:
an information storage submodule, configured to store the received attribute information of the telepresence conference site, as a basis of the conference control; and
an information identification submodule, configured to identify each of the conference sites according to the attribute information of each of the conference sites.

10. The multipoint control unit according to claim 8 , wherein the conference control module comprises:
a request message receiving submodule, configured to receive a conference control request message carrying stream information; wherein the stream information comprises one or any combination of the following items: stream information of a life-size image of the telepresence conference site, stream information of a panoramic image of the telepresence conference site, stream information of a slide of the telepresence conference site, primary stream information of a common conference site, and auxiliary stream information of the common conference site;
a request message resolution submodule, configured to resolve the conference control request message according to the attribute information of the first telepresence conference site; and
a stream processing submodule, configured to perform corresponding stream processing according to the conference co
