Abstract

The invention relates to a high speed motor-car set vehicle television function debugging method. The method comprises steps that, 1, CVBSA IN interfaces of a DVD player and an audio encoder are connected by utilizing coaxial cables; 2, an audio encoder ASI OUT2 interface is connected with an ASI IN interface of a digital modulator, a right channel interface of the audio encoder is connected with an XLR R interface of an audio and video encoder, and a power source of the DVD player is conducted; 3, an RF OUT interface of the digital modulator is connected with a service interface of a vehicle audio and video host, the power source is further conducted; and 4, any DVD disk having audio and video programs is selected and played through the DVD player, the video programs of the DVD disk can be displayed through a vehicle television, audios can be outputted through a loudspeaker in the vehicle, and thereby vehicle television audio and video function debugging is realized. The high speed motor-car set vehicle television function debugging method is advantaged in that, the debugging scheme is reasonable, the debugging result is accurate, debugging time is shortened, and debugging efficiency is improved.

Description

The adjustment method of EMU vehicle TV functions
Technical field
The present invention relates to a kind of function debugging method of in-car TV, especially relate to a kind of adjustment method of EMU vehicle TV audio frequency and video function.
Background technology
Vehicle electrical visual function adjustment method was the debugging adopting general pictcure generator (analog signal) to carry out vehicle TV in the past, only vehicle TV can be lighted by analog image, and debug the correctness of vehicle TV color display, and the debugging of audio frequency and video functional effect cannot be realized.
Summary of the invention
The object of this invention is to provide a kind of method of debugging the audio frequency and video function of vehicle tv effect, be conducive to the failure rate of reduction equipment, improve debugging efficiency.
For achieving the above object, the invention provides a kind of adjustment method of EMU vehicle TV functions, it is characterized in that comprising the following steps:
1, coaxial cable is used to connect the CVBSAIN interface of DVD player and audio coder;
2, audio coder ASIOUT2 interface is connected to the ASIIN interface of digital modulator, and " R channel " interface of audio coder is connected to the XLRR interface of audio/video coder, and connects the power supply of DVD player;
3, digital modulator interface RFOUT is connected with " service interface " of vehicle audio frequency and video main frame, and switches on power;
4, optionally a have the DVD CD of audio/video program to be play by DVD player, and vehicle TV can show the video frequency program of DVD CD, and audio frequency is exported by internal loudspeaker, thus realizes the debugging of vehicle TV audio frequency and video function.
The advantage that the present invention has relative to prior art and progress:
(1) debugging plan is reasonable;
(2) debug results is accurate;
(3) decrease debug time, improve debugging efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is the structure composition frame chart of the debug system that the inventive method uses.
Embodiment
With reference to Fig. 1, the concrete implementation step of adjustment method:
(1) " video " interface of DVD player is connected to the CVBSAIN of audio coder, " R channel " interface is connected to the XLRR of audio/video coder, and connects the AC220V supply power voltage of DVD player;
(2) the ASIOUT2 BNC cable of audio coder is connected to the ASIIN of digital modulator;
(3) the interface RFOUT of digital modulator is connected with " service interface " of vehicle audio frequency and video main frame by the RG59 coaxial cable using the coaxial cable used with debugging vehicle to match, and connects DC110V voltage;
(4) the optional a DVD CD having audio/video program, play by DVD player, vehicle TV can show the video frequency program of DVD CD, and audio frequency is exported by internal loudspeaker.

Claims (1)

1. an adjustment method for EMU vehicle TV functions, is characterized in that comprising the following steps:
(1) coaxial cable is used to connect the CVBSAIN interface of DVD player and audio coder;
(2) audio coder ASIOUT2 interface is connected to the ASIIN interface of digital demodulator, and " R channel " interface of audio coder is connected to the XLRR interface of audio/video coder, and connects the power supply of DVD player;
(3) digital demodulator interface RFOUT is connected with " service interface " of vehicle audio frequency and video main frame, and switches on power;
(4) optionally a have the DVD CD of audio/video program to be play by DVD player, and vehicle TV can show the video frequency program of DVD CD, and audio frequency is exported by internal loudspeaker, thus realizes the debugging of vehicle TV audio frequency and video function.
