Abstract

The invention relates to a system for carrying out broadcasting control on an ATSC (Advanced Television System Committee) signal at a television station end, which comprises an ATSC signal receiving device, a processor, a sound playing device, a storage and a wireless communication device. The processor is connected with the ATSC signal receiving device, the sound playing device, the storage and the wireless communication device; and when the processor carries out analysis to find the abnormal condition in a digital television signal received by the ATSC signal receiving device, the sound playing device is triggered to send a sound alarm signal, the storage is triggered to start to store audio data and video data of a digital television program with the abnormal condition, and the wireless communication device is triggered to send the information of the digital television program with the abnormal condition. By the broadcasting control system, a plurality of paths of digital television programs in the ATSC signal at the television station end can be monitored in real time so as to timely give an alarm and process when the abnormal condition is generated.

Description

technical field [0001] The invention relates to the field of ATSC television broadcasting, in particular to a broadcasting control system of ATSC signals at a television station. Background technique [0002] There are two main camps in existing digital TV transmission standards, one is the American ATSC standard, and the other is the European DVB standard. Among them, the full English name of ATSC is Advanced Television Systems Committee (Advanced Television Business Advisory Committee). On September 15, 1995, the committee formally passed the ATSC digital TV national standard. ATSC source coding adopts MPEG-2 video compression and AC-3 audio compression; channel coding adopts VSB modulation, and provides two modes: terrestrial broadcast mode (8VSB) and high data rate mode (16VSB). ATSC standards are widely used, especially in North American countries and regions. [0003] However, due to bandwidth limitations and problems with the digital TV program source itself, probl...
