Embodiment 1

[0041] like figure 1 As shown, a system supporting dynamic transmission of multi-stream streaming media, including

[0042] Multi-stream streaming media dynamic sending module 11 dynamically updates the transmission configuration of the streaming media data sent, outputs transmission configuration information, collects multi-stream streaming media data according to the transmission configuration information, and pre-configures the multi-stream streaming media data collected Send after processing and encoding;

[0043] The multi-stream streaming media dynamic transmission module 12 is connected with the multi-stream streaming media dynamic sending module 11, obtains and stores the transmission configuration information of the multi-stream streaming media dynamic sending module 11 dynamic update, and simultaneously sends the multi-stream streaming media dynamic sending module Stream streaming media data is stored and transmitted in real time, and the multi-stream streaming medi...

Embodiment 2

[0062] like Figure 4 As shown, a system supporting dynamic transmission of multi-stream streaming media includes a dynamic publishing module of multi-stream streaming media, a dynamic transmission module of multi-stream streaming media and three dynamic receiving modules of multi-stream streaming media. Among them, the multi-stream streaming media dynamic sending module can dynamically configure the sent media streams during the transmission process, including selecting which media channels to send, and performing one or more encoding specification options for each sent media channel Send after preprocessing and encoding. The multi-stream streaming media dynamic transmission module obtains the dynamic update of the transmission module transmission configuration in time, and notifies the corresponding multi-stream streaming media dynamic receiving module; the dynamic transmission module is also responsible for the real-time network transmission function of multi-stream streami...

Abstract

The invention relates to a system for supporting multithread streaming media dynamic transmission. The system comprise a multithread streaming media dynamic sending module, a multithread streaming media dynamic transmission module and a multithread streaming media dynamic receiving module, wherein the multithread streaming media dynamic sending module can be used for carrying out transmission configuration on sent media in a transmission process, selecting a media channel for sending, and sending each media channel for sending, which is preprocessed and encoded according to an encoding standard in the transmission configuration; the multithread streaming media dynamic transmission module is used for obtaining and storing the dynamically updated transmission configuration information, and storing and transmitting multithread streaming media data simultaneously in real time; and the multithread streaming media dynamic receiving module is used for obtaining a subset of the multithread streaming media data sent by a transmission configuration information obtaining and sending module, and then playing the multithread streaming media data after decoding, pre-treating and synchronizing the multithread streaming media data. Compared with the prior art, the system provided by the invention has the advantages of supporting multithread streaming media transmission, carrying out the dynamic transmission configuration in the transmission process, and the like.

Description

technical field [0001] The invention relates to a system in the technical field of network information transmission, in particular to a system supporting dynamic transmission of multi-stream streaming media. Background technique [0002] With the continuous upgrading of network infrastructure, the bandwidth of wired and wireless networks has been significantly improved compared to before, and the transmission of real-time audio, video and other streaming media applications on the network has gradually become popular and has become a popular application. However, network resources are dynamically changing and unpredictable. The current network generally can only provide best-effort services, and cannot guarantee safe access in any environment and scenario. And in many application scenarios, a two-way streaming media application that only supports voice and video cannot meet the needs of practical applications. For example, in the real-time teaching scene, in addition to supp...
