Problems solved by technology

[0003] However, due to bandwidth limitations and the problems of the digital TV program source itself, problems such as black frames, color bars, video freeze frames, and audio mutes are prone to occur during DVB-C broadcasting. If the TV station broadcasts these problematic TV content, That would cause a broadcast accident, which would have a negative impact on the image of the TV station, and at the same time reduce the ratings of the TV station, thus bringing considerable economic losses to the TV station.

Abstract

The invention relates to a real-time monitoring system for a digital video broadcasting (DVB-C) television signal. The real-time monitoring system for the DVB-C television signal comprises a DVB-C television signal receiving device, a processor, an audio player and a storage unit. The processor is connected with the DVB-C television signal receiving device, the audio player and the storage unit. When the condition that the digital television signal received by the DVB-C television signal receiving device is abnormal is analyzed out by the processor, the audio player is triggered to send out an audio alarm signal and the storage unit is triggered to start to store voice data and video data of abnormal digital television programs. By the real-time monitoring system for the DVB-C television signal disclosed by the invention, multichannel digital television programs under the DVB-C television signal can be monitored in real time so as to give an alarm and perform processing in time when an abnormal condition occurs.

Description

technical field [0001] The invention relates to the field of cable digital television broadcasting DVB-C, in particular to a real-time monitoring system for DVB-C television signals. Background technique [0002] Digital TV broadcasting DVB-C standard is one of the most widely used digital TV standards in the world at present. The cable digital TV broadcasting DVB-C is to send digital TV broadcasting signals to thousands of households by means of wired cables. DVB-C It is also a more common digital TV broadcast mode than terrestrial digital TV broadcast DVB-T and satellite digital TV broadcast DVB-S, and it is also the most widely used broadcast signal construction mode by various TV stations. [0003] However, due to bandwidth limitations and the problems of the digital TV program source itself, problems such as black frames, color bars, video freeze frames, and audio mutes are prone to occur during DVB-C broadcasting. If the TV station broadcasts these problematic TV conte...
