Description

technical field [0001] The invention relates to the technical field of a rail transit audio and video monitoring collection system and a network audio and video playback system, in particular to an analog audio and video collection and multimedia playback system. Background technique [0002] The existing train monitoring system needs to collect analog audio and video, and uses an analog camera to collect monitoring video, and the monitoring video of the analog camera is stored and operated in a centralized manner. The train video system uses a digital network to download the voice video data stream through a centralized video server, and after decoding by the processor, the display information is output to the LCD display. In the current mode, the two systems are independent of each other, and there is no intersection in hardware. And the present invention realizes analog audio signal and analog camera video signal collection and encoding into network video stream and uploa...
