Embodiment Construction

[0021] 1. The highly scalable CPCI bus structure is adopted, and each board processing unit adopts a modular design, which can work independently and cooperate with each other to achieve a high degree of unity and loose coupling.

[0022] 2. The 4U chassis adopts CPCI architecture, and there are two rows of slots inside, one for demodulation cards and one for control cards.

[0023] The demodulation card can make corresponding demodulation and index measurement work according to the input signal. The signal types currently supported are: analog TV signal, cable digital TV DVB-C standard signal, terrestrial digital TV (in line with China GB20600-2006 standard) signal , Mobile multimedia broadcasting CMMB signal. The demodulation card demodulates the signal and outputs it to the control card, and completes the transcoding work here, supporting stream types of different code rates and formats.

[0024] 3. The upper and lower sides of the card are fixed by guide rails. The front ...

Abstract

The invention relates to a television monitoring system based on a modular framework and equipment. The equipment of the system is radio and television monitoring equipment employing a compact personal communication interface (CPCI) modular chassis design. The system is mainly applied to content monitoring, quality analysis, code stream index detection, radio frequency index monitoring, information acquisition, data display and other monitoring work in the field of radio and television. The system can support monitoring of signals in various modes through configuration, such as analog television signals, cable digital television DVB-C standard signals, signals of terrestrial digital televisions (meeting GB20600-2006 standard in China) and China mobile multimedia broadcasting (CMMB) signals. Meanwhile, a board card module of the equipment is flexibly configured aiming at different monitoring services, so that the effect that one machine has multiple purposes is achieved. Moreover, the requirements on adaptability, flexibility and reliability of a digital radio and television monitoring system are met.

Description

technical field [0001] The invention relates to the technical field of digital television monitoring systems, in particular to a television monitoring system based on modular framework and equipment. Background technique [0002] With the digitalization of broadcast and TV content and operations, the monitoring field has also put forward the requirements on how to face digitalization. The development of radio and television digitalization is not just a formal conversion from analog to digital, but more diversified transmission methods (cable, terrestrial, CMMB, and terrestrial digital TV itself has single-carrier and multi-carrier), content forms It is more diversified (only video has MPEG2 / 4, H. 264, AVS and other encoding methods), and the content protection method is more complicated (CA, watermark, DRM), so the monitoring is not just from monitoring some of the analog TV Indicators have been converted to several indicators for monitoring digital TV, but put forward high...
