The utility model discloses the system is simple reliable, and the debugging scheme is reasonable, test results is accurate, the the debugging time is shortened, debugging efficiency has been improved.
Description
Technical field
The utility model relates to a kind of function debugging system of in-car TV, especially relates to a kind of debug system of EMU vehicle TV audio frequency and video function.
Background technology
Vehicle electrical visual function debug system 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.
Utility model content
The purpose of this utility model is to provide a kind of audio frequency and video function system debugging vehicle tv effect, is conducive to the failure rate of reduction equipment, improves debugging efficiency.
For achieving the above object, the utility model provides a kind of debug system of EMU vehicle TV functions, it is characterized in that: comprise DVD player, audio coder, audio/video coder, digital modulator, vehicle audio main frame, " video " interface of DVD player is connected with the CVBSAIN interface of audio coder; 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; Digital modulator interface RFOUT is connected with " service interface " of vehicle audio frequency and video main frame, and switches on power, and audio frequency is exported by internal loudspeaker.
The advantage that the utility model has relative to prior art and progress:
(1) system is simple and reliable, and debugging plan is reasonable;
(2) debug results is accurate;
(3) decrease debug time, improve debugging efficiency.
Accompanying drawing explanation
Accompanying drawing 1 is structure composition frame chart of the present utility model.
