Internet-based video-audio transmission system and video-audio stream distribution method thereof

Abstract

The invention discloses an Internet-based video-audio transmission system and a video-audio stream distribution method thereof. The system comprises a front-end subsystem, a client subsystem, and a central service platform; besides, the central service platform includes a client application server, a service management subsystem, an alarm service subsystem, an authentication, authorization, accounting (AAA) server, a platform management subsystem, a scheduling subsystem, a storage subsystem, a distribution subsystem, a control service subsystem, and a front-end application server. In addition, the invention also discloses a video-audio stream distribution method of the Internet-based video-audio transmission system. The scheduling subsystem carries out reasonable scheduling on videos and audios of the distribution subsystem according to a current using situation of the system; and the distribution subsystem sends video and audio streams to a client terminal having demand; according to scheduling information of the scheduling subsystem. According to the invention, the system and the method thereof have the following advantages: simultaneous access to and use of a same video-audio stream by multiple users is supported; it is convenient to manage the system; and the application range is wide, and so on.

Description

technical field [0001] The invention relates to a video and audio transmission technology, in particular to an Internet-based video and audio transmission system and a video and audio stream distribution method thereof. Background technique [0002] With the continuous advancement of electronic information technology, people's communication methods are also constantly improving. Traditional communication methods such as letters and telephones are far from meeting people's communication needs. Video and audio transmission is a way for people to use vision and hearing to obtain information. A communication method, which has the advantages of intuition, accuracy and high efficiency compared with other communication methods. Video and audio transmission technology has been widely used in various fields such as remote visual international business service platform, real-time video conferencing, online live broadcast, distance education, telemedicine, Internet radio, etc. The deve...

Problems solved by technology

The architecture of the video and audio transmission system used in the prior art all adopts a single mode of front-end to client. The client directly obtains the video and audio stream from the front-end video and audio encoder. When multiple clients access one video and audio stream at the same time, the The front-end video and audio encoder and the network connected to it cause great pressure and easily form a bottleneck, and the similar systems currently in use are relatively closed and cannot be directly integrated with the customer's dedicated system
