Cloud broadcasting system and method

Abstract

The invention relates to a cloud broadcasting system and method, and belongs to the technical field of broadcasting-television broadcasting control. The system comprises stream media broadcasting server control processing devices, stream matrix control processing devices and program compiling and broadcasting application control devices. The multiple stream media broadcasting server control processing devices and the multiple stream matrix control processing devices can be deployed in a distributed mode, and constitute a stream media broadcasting cloud and a stream matrix control cloud respectively. According to the cloud broadcasting system and method, stream media broadcasting, stream matrix control, and program compiling and broadcasting application are integrated, material programs are played and switched accurately in an IP stream mode, efficient and accurate broadcasting of the content of the material programs is achieved, and broadcasting safety of the system is enhanced.

Description

technical field [0001] The invention belongs to the technical field of radio and television broadcast control, and in particular relates to a cloud broadcast system and method. Background technique [0002] In the radio and television system, whether the content of broadcast programs is legal or not involves national security, social stability and national image, which is a very critical issue. Only legal programs can be used for broadcasting. In the existing radio and television system, the content of broadcasting programs requires accurate switching, ensuring uninterrupted broadcasting, improving the safety of broadcasting and the response speed to fault handling, ensuring the safety of program broadcasting, and ensuring the viewing needs and perceptions of the people. [0003] The traditional SDI broadcast method needs to use the SDI video server to broadcast the SDI signal, which is connected to the peripheral equipment and the switcher via the audio and video cable.

Problems solved by technology

It can be divided into two types: unicast and multicast. The number of on-demand channels supported by a single server is usually hundreds of channels. The parallel performance is excellent, but the connection and switching of programs cannot be accurate, and static frames, blurred screens or Intolerable problems such as mosaics and even black spots, and hundreds of channel switching at the same time are more difficult to control and meet the broadcast safety level requirements

At the same time, the existing IP broadcast mode lacks backup and emergency mechanisms. It usually runs on a single machine. Once a failure occurs, it cannot automatically switch to the backup line, which cannot meet the requirements of uninterrupted broadcasting.
