Problems solved by technology

[0006] The first recording and broadcasting method, because the TV terminal only records and stores the data of itself or the received single-channel media stream separately, it cannot perform some combined recording processing on the data of multiple audio, video and other media streams , such as multi-screen, picture-in-picture and other image forms
[0007] The second recording and broadcasting method, because the detection recording and broadcasting server captures the communication data packets on the network, and then extracts the audio and video data for separate recording and storage, it is also impossible to combine the data of multiple audio, video and other media streams recording processing

Embodiment 1

[0063] Such as figure 1 As shown, the embodiment of the present invention provides a method for recording a multimedia conference, including:

[0064] Step 11: Obtain multiple conference media streams to be recorded determined according to the conference-level recording policy, where the conference media streams are at least video media streams or audio media streams;

[0065] Step 12: Combine and record the multiple conference media streams according to the media recording policy.

[0066] Optionally, the execution subject of the method for recording a multimedia conference may be a recording server, see Figure 13 As shown, the recording server is connected to the multipoint control unit (multipoint control unit MCU). When the multipoint control unit MCU is connected to at least one conference terminal, the multi-channel conference media stream to be recorded is obtained according to the conference-level recording strategy. Step 11 may specifically include:

[0067] Send ...

Embodiment 2

[0096] Refer to the method for recording a multimedia conference provided in the first embodiment above, such as figure 2 As shown, an embodiment of the present invention provides a recording device for a multimedia conference that can implement the above recording method, including:

[0097] The receiving module 21 is configured to receive multiple conference media streams to be recorded determined according to a conference-level recording policy, where the conference media streams are at least video media streams or audio media streams.

[0098] The recording processing module 22 is configured to perform combined recording processing on the multiple conference media streams according to the media recording policy.

[0099] Such as image 3 As shown, optionally, the receiving module 21 may include:

[0100] The policy sending module 211 is used to send the conference-level recording policy to the multipoint control unit MCU, the conference-level recording policy includes: ...

Embodiment 3

[0116] Corresponding to the method for recording a multimedia conference provided in Embodiment 1 of the present invention, such as Figure 4 As shown, the embodiment of the present invention provides a playback method of a multimedia conference, including:

[0117] Step 41: Receive a playback request carrying a media identifier, where the media identifier is used to identify a media file.

[0118] Step 42: Obtain the corresponding media file according to the media identifier for playback. The media file is obtained by combining and recording multiple conference media streams in the multimedia conference according to the recording strategy.

[0119] The execution subject of the playback method of a multimedia conference in the embodiment of the present invention may be a recording server.

[0120] The playback method of the multimedia conference in the embodiment of the present invention may further include: before the recording server receives the playback request carrying t...

Abstract

The embodiment of the invention provides a recording method, a device and a system of a multimedia conference. The recording method of the multimedia conference comprises the following steps of performing combined recording treatment to the data (at least video data, audio-frequency data or image data) of a multi-channel media stream in the multimedia conference. Since the combined recording treatment to the multi-channel media stream in the multimedia conference can be realized as per a recording strategy, the comprehensive situation of the multimedia conference can be shown better, and the recording strategy can be arranged flexibly.

Description

technical field [0001] The invention relates to the technical field of communication, in particular to a recording method, a playback method, a recording and broadcasting device and a recording and broadcasting system of a multimedia conference. Background technique [0002] At present, the recording and broadcasting methods of multimedia conferences are usually in the following forms: [0003] A way for a terminal to realize recording and broadcasting is: integrating a recording and broadcasting system in a traditional TV terminal, enabling the recording function of the TV terminal during a multimedia conference, recording and storing local audio, video and other media stream data of the TV terminal, Or record and store the remote audio, video and other media stream data of other TV terminals received by the TV terminal. After the multimedia conference is over, the recorded data content of the media stream can be played back and viewed through the TV terminal. [0004] Ano...
