Embodiment 1

[0052] According to an embodiment of the present invention, a method for direct communication between terminals in a multipoint conference is provided, such as figure 1 As shown, it is used for the sending end, and specifically includes the following steps:

[0053] Step 101, forward the code stream direct request signaling to the receiving end through the multi-point control unit.

[0054] Specifically, in this step, after receiving an instruction requiring interaction between two terminals, the sending end generates code stream direct request signaling according to the configuration information, and sends the signaling to the multipoint control unit. The configuration information here can be preset for the terminal, and can also be configured by the user according to actual needs. Among them, when generating the code stream direct request signaling, it includes:

[0055] Configure the stream operation type field as the request type;

[0056] Set the stream type field to a...

Embodiment 2

[0073] According to an embodiment of the present invention, a method for direct communication between terminals in a multipoint conference is provided, such as figure 2 As shown, it is used at the receiving end, and specifically includes the following steps:

[0074] Step 201: Receive code stream direct connection request signaling sent by the sender forwarded by the multipoint control unit, and generate code stream direct connection confirmation signaling according to the code stream direct connection request signaling.

[0075] In this step, after receiving the code stream straight-through request signaling, analyze the signaling to obtain the field information contained in the signaling, and generate a code stream straight-through confirmation instruction according to the field information combined with the actual situation of the local end and feed it back through the multi-point control unit to the sender.

[0076] Specifically, when generating the code stream direct co...

Abstract

The invention discloses a method and device for direct communication between terminals in a multipoint conference and a storage medium. The method comprises the following steps: a code stream straight-through request signaling is forwarded to a receiving terminal via a multi-point control unit, a code stream straight-through confirmation signaling which is fed back via the receiving terminal and forwarded via the multi-point control unit is received, and straight-through code stream interaction with the receiving terminal is performed according to the code stream straight-through confirmationsignaling which is fed back. Via the method and device for direct communication between terminals in multipoint conference and the storage medium disclosed in the invention, an MCU can be prevented from code stream forwarding and processing operation, audio and video time delays of the two terminals can be reduced, and usage scenarios of multipoint conference terminals can be enriched while MCU performance and bandwidth remain unaffected.

Description

technical field [0001] The present invention relates to the technical field of multimedia communication, in particular to a method, device and storage medium for direct communication between terminals in a multipoint conference. Background technique [0002] Videoconferencing usually has two usage modes, point-to-point conference and multipoint conference. A point-to-point conference is a point-to-point direct communication between two participants in different locations. A multipoint conference is a conference that allows participants from two or more different locations to participate simultaneously. Due to the limited processing capability of videoconferencing terminals, MCU (Microcontroller Unit, microcontroller) is usually used as the core device in video conferences in multipoint conferences, which is responsible for signaling exchange and code stream exchange with videoconferencing terminals or other MCUs. Forward or process. [0003] In a multipoint conference, wh...
