Embodiment Construction

[0012] Below in conjunction with accompanying drawing, the present invention is described in further detail, so that those skilled in the art understand:

[0013] Such as figure 1 As shown, the labels represent:

[0014] Server 1, playback terminal 2, mobile TV 21, microprocessor 211, speaker 212, display 213, antenna 214, FM modulation circuit 215, signal receiver 22, mobile phone 3.

[0015] see figure 1 As shown, the present embodiment provides a mobile TV playback system for public transport, which has the same structure as the existing mobile TV playback system, including a server 1 and multiple playback terminals installed on public transport. The server 1 provides playback content for each playback terminal in a wireless communication manner. The playback terminal includes a mobile TV 21 and a signal receiver 22 capable of establishing a wireless communication connection with the server 1 . The microprocessor 211 circuit of the mobile TV 21 is connected to the signa...

Abstract

The invention relates to a mobile TV playing system for a public transport means. The mobile TV playing system comprises a server and a playing terminal mounted on the public transportation means. The playing terminal comprises a mobile TV and a signal receiver, a microprocessor of the mobile TV receives playing content issued by the server through the signal receiver and decodes the playing content to generate analog audio signals and analog video signals, and a loudspeaker and a displayer of the mobile TV correspondingly receive and play the signals. The mobile TV further comprises an antenna and an FM modulator circuit which is connected with the microprocessor, the FM modulator circuit receives the analog audio signal and modulates the analog audio signal into a carrier signal which can be accepted by an FM receiver, and the antenna is connected with the FM modulator circuit. Thus, all playing terminals send the voices of television programs in an FM carrier signal mode, passengers who expect to watch the mobile TV can receive the voices of the television programs through mobile phones and earphones with the FM function. Meanwhile, the loudspeaker volume of the playing terminal does not need to be too loud, and passengers who do not want to watch the programs can not be disturbed.

Description

technical field [0001] The invention relates to the technical field of vehicle-mounted mobile televisions, in particular to a mobile television broadcasting system used in public vehicles. Background technique [0002] Vehicle-mounted mobile TV has been used in more and more public transportation vehicles. It has four major advantages: wide spread, fast spread, long contact time, and stable group structure. This just fills the gap in domestic traditional media. For example, the Oriental Pearl Mobile TV in Shanghai has 210,000 bus viewing terminals (as of April 2013), and the programs are broadcast to tens of millions of citizens every day, forming an influential outdoor digital mobile TV information platform in Shanghai. [0003] However, due to the noisy environment of public transport, the sound of station announcements in the compartment, the sound of passengers talking, the roar of the engine, and the mechanical noise of the motor vehicle running will not only affect the...
