Audio and video conference implementation method, audio and video conference system, and related apparatus

An audio and video conference system, comprising a data transmission network and a room management subsystem, wherein:

• the data transmission network being configured to transmit a media data stream generated in a conference room, the data transmission network comprising multiple device groups, and each device group comprising multiple interface machines;
• each of the multiple interface machines being configured to connect to a conference accessing terminal, the conference access terminal accessing the conference room by using the interface machine;
• a retrieval device existing in each device group in the multiple device groups, a retrieval device in a first device group being configured to receive an application to pull data stream from a first interface machine in the first device group, the application to pull data stream comprising first identification information of a media data stream, and forward the media data stream corresponding to the first identification information to the first interface machine, the media data stream being obtained by the retrieval device in the first device group from a second interface machine in a second device group, a data generating terminal that generates the media data stream accessing the conference room by using the second interface machine, and the first device group and the second device group each being any one of the multiple device groups;
• the first interface machine being an interface machine in the first device group, and the first interface machine being configured to forward the media data stream to a corresponding conference access terminal;
• and
• the room management subsystem comprising the multiple device groups and a central server, each device group comprising an intra-group server, and the intra-group server being configured to assist the central server in managing the conference room.

A non-transitory computer readable storage medium, configured to store computer program code, when running on a retrieval device in a first device group of an audio and video conference system, causing the retrieval device in the first device group to perform:

• receiving, by the retrieval device in the first device group, an application to pull data stream from a first interface machine in the first device group, the application to pull data stream comprising first identification information of a media data stream, the audio and video conference system comprising a data transmission network and a room management subsystem, the first device group being a device group in multiple device groups of the data transmission network, the data transmission network being configured to transmit the media data stream generated in a conference room, a retrieval device existing in each device group, each device group comprising multiple interface machines, and each interface machine being configured to connect to a conference accessing terminal that accesses the conference room by using the interface machine;
• the first interface machine being in the first device group, wherein the room management subsystem comprises the multiple device groups and a central server, each device group comprising an intra-group server, and the intra-group server being configured to assist the central server in managing the conference room;
• and
• forwarding, by the retrieval device in the first device group, the media data stream corresponding to the first identification information to the first interface machine, the first interface machine forwarding the media data stream to the conference accessing terminal;
• the media data stream being obtained by the retrieval device in the first device group from a second interface machine in a second device group, a data generating terminal that generates the media data stream accessing the conference room by using the second interface machine, and the second device group being a device group in the multiple device groups.
