The bus multimedia release system is composed of car-mounted display equipment such as the front main screen in the bus, LCD bus stop information display screen, LED rear full-color screen, car-mounted advertising machine, and LCD screen in the middle of the bus. Multimedia information such as texts, pictures, and videos can be released on the car-mounted display screens via the remote control of the multimedia management platform software, which covers multimedia information both inside and outside the bus compartment, making passenger travel more convenient through IT-based public transport management, and is also applicable to long-distance passenger transport and scenic area fixed-route vehicles.
