Radio and television full-service three-level diagnostic method and safety broadcasting service system

Abstract

The invention discloses a radio and television full-service three-level diagnosis and safety broadcasting service system. The system comprises a plurality of signal acquiring and returning devices, a monitoring server and a monitoring client. The plurality of signal acquiring and returning devices are disposed at positions of a central apparatus room, sub-headends and optical nodes; the monitoring server is disposed in the central apparatus room and provided with a safety content library, and the safety content library is used for storing legal, safe and qualified contents to provide a content comparison basis; the monitoring server is used for receiving image data returned by the signal acquiring and returning devices and selecting image data to compare with contents in the safety content library; the monitoring client is used for displaying alarm information and monitoring images outputted by the monitoring server. Compared with monitoring techniques in the radio and television industry, the system has the advantage that by setup of an image comparison mechanism of the safety content library, monitoring precision and practical value are higher than those of a traditional TS (transport stream) audio-video decoding output monitoring mode. By adoption of terminal virtualization technology for directly eliminating faults and inspecting sub-headend terminal services, fault elimination time is greatly shortened, and operation and maintenance efficiency can be improved greatly.

Description

technical field [0001] The invention relates to the field of digital television, in particular to a three-level diagnostic method for all radio and television services and an broadcast service system. Background technique [0002] Safe broadcasting has always been an issue that the radio and television industry attaches great importance to. The content information monitoring transmitted by the digital TV signal is an important means of safe broadcasting guarantee. As digital TV signals carry more and more services, in order to ensure safe broadcasting, more and more content information needs to be monitored. [0003] At present, the main technologies for content monitoring in the broadcasting industry include: [0004] 1), IP construction [0005] Obtain the multicast code stream in the local area network through the IP network, and the signal can be uniformly dispatched and the multi-screen display monitoring host can be deployed in a centralized manner. [0006] 2) Vid...

AI Technical Summary

Problems solved by technology

[0014] A) The monitoring of the traditional radio and television industry can only monitor the video and audio of digital TV, and there is no effective safe broadcast guarantee technology for systems such as graphic information (email, OSD, etc.), value-added services (EPG advertisements, etc.), and Effective full-service content monitoring cannot be realized

[0015] B) The traditional way of thinking about safety broadcast monitoring is to add a set of safety broadcast monitoring equipment for each additional business (system), but with the rapid development of digital TV business, there are more and more value-added services. According to this idea, it is bound to cause investment Many problems, many systems, difficult operation and maintenance, many personnel, and chaotic fault handling are tantamount to making the already fragile business model of the traditional broadcasting industry worse

[0016] C) Fault location is not clear, too many unnecessary fault location and troubleshooting work will inevitably increase the operation and maintenance costs of radio and television operators; at the same time, excessive fault processing time will also expand the impact of faults
