Abstract

A method for playing a conference signal, a video conference terminal, and a mobile device, related to the field of communications technologies, are provided to improve effects of displaying a main stream signal and a presentation stream signal. The method includes establishing a connection channel between a mobile device held by a conference participant and a video conference terminal that are at a site; sending, through the established connection channel, a first type signal in to-be-played signals to the mobile device for play, where the to-be-played signals are signals that are received by the video conference terminal and are to be played; and sending a second type signal in the to-be-played signals to a primary playing device of the site for play.

First claim

What is claimed is:

1. A method for playing a conference signal, comprising:
establishing a connection channel between a plurality of mobile devices held by a plurality of conference participants located at a site and a video conference terminal located at the site, wherein the video conference terminal comprises a primary playing device;
sending, through the established connection channel, a first type signal in to-be-played signals to each of the mobile devices for play, wherein the to-be-played signals are signals that are received by the video conference terminal and are to be played; and
sending a second type signal in the to-be-played signals to the primary playing device of the site for play,
wherein the first type signal is a presentation stream signal when the second type signal is a main stream signal, or the first type signal is the main stream signal when the second type signal is the presentation stream signal,
wherein the presentation stream signal comprises at least one of a document and a demonstration slide to be displayed, and
wherein the main stream signal comprises real-time content to be displayed.

2. The method according to claim 1 , wherein before the sending of the first type signal in the to-be-played signals to each of the mobile devices, the method further comprises sending classification information of the to-be-played signals to each of the mobile devices to instruct each of the mobile devices to determine, according to the classification information of the to-be-played signals, a play request message comprising information about a signal requested to be played by each of the mobile devices, and wherein sending of the first type signal in the to-be-played signals to each of the mobile devices comprises sending, to each of the mobile devices according to the play request message received from each of the mobile devices, the first type signal that is in the to-be-played signals and is requested to be played by each of the mobile devices.

3. The method according to claim 1 , wherein the first type signal includes a plurality of different subtype signals, and wherein sending the first type signal to each of the mobile devices for play comprises:
sending a first information about the different subtype signals included in the first type signal to each of the mobile devices;
receiving a second information about a subtype signal requested to be played that is sent by each of the mobile devices according to the first information about the different subtype signals; and
sending the subtype signal that is requested to be played by each of the mobile devices and included in the different subtype signals to each the mobile devices that sends the second information about the subtype signal requested to be played for play.

4. The method according to claim 1 , wherein the first type signal includes a plurality of different subtype signals, and wherein the sending of the first type signal to each of the mobile devices for play comprises:
sending a first information about the different subtype signals included in the first type signal to each of the mobile devices;
receiving a second information about a subtype signal requested to be played that is sent by each of the mobile devices according to the first information about the different subtype signals; and
sending the subtype signal that is requested to be played by the mobile devices and included in the different subtype signals to each of the mobile devices at the site for play.

5. A method for playing a conference signal implemented by a mobile device, comprising:
establishing a connection channel between the mobile device held by a conference participant located at a site and a video conference terminal located at the site, wherein the video conference terminal comprises a primary playing device;
receiving, through the established connection channel, a type of signal that is sent by the video conference terminal, wherein the type of signal is selected from to-be-played signals comprising at least two different types of signals; and
playing the type of signal selected from the to-be-played signals comprising the at least two different types of signals,
wherein another type of signal selected from the to-be-played signals comprising the at least two different types of signals is played at the primary playing device,
wherein the type of signal is a presentation stream signal or a main stream signal,
wherein the presentation stream signal comprises at least one of a document and a demonstration slide to be displayed, and
wherein the main stream signal comprises real-time content to be displayed.

6. The method according to claim 5 , wherein before receiving the type of signal that is sent by the video conference terminal and selected from the to-be-played signals, the method further comprises:
receiving, through the established connection channel, classification information of the to-be-played signals that is sent by the video conference terminal;
determining, according to the received classification information, information about a signal requested to be played; and
sending a play request message comprising the determined information about the signal to the video conference terminal, and
wherein receiving the type of signal that is sent by the video conference terminal and selected from the to-be-played signals comprises receiving, through the established connection channel, the type of signal that is selected by the video conference terminal according to the information about the signal comprised in the play request message from the to-be-played signals comprising at least two different types of signals.

7. The method according to claim 5 , wherein the type of signal includes a plurality of different subtype signals, and wherein receiving the type of signal sent by the video conference terminal includes:
receiving, through the connection channel, a first information about the different subtype signals included in the type of signal, wherein the information is sent by the video conference terminal;
sending, to the video conference terminal through the connection channel according to the received first information about the different subtype signals included in the type of signal, a second information about a subtype signal requested to be played; and
receiving, through the connection channel, the subtype signal selected by the video conference terminal according to the second information about the subtype signal requested to be played, from the different subtype signals included in the type of signal in the to-be-played signals.

8. A video conference terminal, comprising:
a processor configured to establish a connection channel between a plurality of mobile devices held by a plurality of conference participants located at a site and the video conference terminal located at the site; and
a signal distributor configured to:
send, through the connection channel established by the processor, a first type signal in to-be-played signals to each of the mobile devices for play, wherein the to-be-played signals are signals that are received by the video conference terminal and are to be played; and
send a second type signal in the to-be-played signals to a primary playing device of the site for play,

wherein the first type signal is a presentation stream signal when the second type signal is a main stream signal, or the first type signal is the main stream signal when the second type signal is the presentation stream signal,
wherein the presentation stream signal comprises at least one of a document and a demonstration slide to be displayed, and
wherein the main stream signal comprises real-time content to be displayed.
