Problems solved by technology
[0002] With the development of Internet technology, simple voice or text communication can no longer meet people's communication needs, and the demand for online meetings is gradually increasing
However, in a multi-person network conference, when transmitting audio and video media data, due to the delay and jitter of network communication and the difference in the working environment of the client, the transmission of audio and video data in a fixed way cannot adapt to various network environments and customer needs

Embodiment Construction
[0011] Hereinafter, the present invention will be described in detail with reference to the drawings and examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0012] figure 1 Shown is a flow chart of a method for transmitting audio and video of a network conference provided according to a preferred embodiment of the present invention. Such as figure 1 As shown, the network conference audio and video transmission method provided by the preferred embodiment of the present invention includes steps 101-104.
[0013] In step 101, the controller obtains different types of receiving parameters of conference participants, and there are multiple receiving parameters of each type. Wherein, the types of receiving parameters include resolution, codec speed, and network bandwidth. Here, the number of conference participants is at least two. However, the present in...

The invention provides an audio and video transmission method and an audio and video transmission system for a network conference. The method comprises the following steps that: a controller obtains different types of receiving parameters from conference participants, wherein each type comprises a plurality of receiving parameters; the controller performs weighting calculation to obtain differenttypes of transmission parameters according to the receiving parameters and corresponding weights, wherein the transmission parameters of different types have priorities; a conference initiator acquires the different types of transmission parameters from the controller, and transmits audio and video data to the conference participants by a server according to the transmission parameters with relatively higher priorities; and if differences between the receiving parameters and transmission parameters of the conference participants are more than or equal to a preset value and the number of the conference participants of which the differences are more than or equal to the preset value is more than or equal to a preset number, the conference initiator transmits the audio and video data to the conference participants according to the transmission parameters with the priorities of the next level by the server.
Description
technical field [0001] The invention belongs to the technical field of audio and video, and in particular relates to a method and system for transmitting network conference audio and video. Background technique [0002] With the development of Internet technology, simple voice or text communication can no longer meet people's communication needs, and the demand for online meetings is gradually increasing. However, in a multi-person network conference, when transmitting audio and video media data, due to the delay and jitter of network communication and the difference in the working environment of the client, the transmission of audio and video data in a fixed way cannot adapt to various network environments and customer needs. Contents of the invention [0003] The present invention provides a network conference audio and video transmission method and system to solve the above problems. [0004] The invention provides a network conference audio and video transmission met...
