Problems solved by technology
[0002] Before each TV is launched into the market, a series of tests need to be carried out. Generally, the signal source of TV receives external media data, which needs to be input into the demodulation module for demodulation, and then the demodulated data is sent to the display screen, speakers, etc. Play in the playback device, and before the TV leaves the factory, the demodulation module needs to process media data in various formats, and conduct multiple inspections to test the stability of the demodulation module. Generally, this time is relatively long, and the staff cannot always watch the TV. This method of media data is used to detect the continuous working effect of the demodulation module, which is too inefficient and requires a lot of labor

Embodiment Construction
[0019] Such as figure 1 As shown, the TV system for automatic testing of the present invention generally includes a signal source 1, a demodulation module 2 and a TV playback device 3, the signal source 1 is used to receive externally input media data, and the demodulation module 2 communicates with the signal source respectively 1. The playback device 3 is electrically connected to demodulate the media data, and the demodulated data is played through the playback device 3. The playback device 3 here may include a display screen, a speaker, etc., and the signal source 1 here includes One or more of DVI input, AV input, S-Video input, HDMI input, USB input, and BNC input.
[0020] The design also includes a test module 4 and a script storage module 8 storing a test script, the test module 4 is electrically connected to the demodulation module 2 and the script storage module 8 respectively to detect the demodulated data based on the test script, and draws It is the test result ...

The invention discloses an automatic test television system, comprising a signal source for receiving externally input media data, a playing device and a demodulation module. The demodulation module is electrically connected with the signal source and the playing device to demodulate the media data and plays the demodulated data through the playing device. The television system also comprises a test module and a script storage module in which test scripts are stored. The test module is electrically connected with the demodulation module and the script storage module to detect the demodulated data based on the test scripts, and a test result for judging whether disordered information exists in the demodulated data or not is obtained. According to the design, a great deal of labor is saved, a worker only needs to start the television system and then a test can be carried out, the test result is accurate.
Description
technical field [0001] The invention relates to a television system, in particular to an automatic testing television system. Background technique [0002] Before each TV is launched into the market, a series of tests need to be carried out. Generally, the signal source of TV receives external media data, which needs to be input into the demodulation module for demodulation, and then the demodulated data is sent to the display screen, speakers, etc. Play in the playback device, and before the TV leaves the factory, the demodulation module needs to process media data in various formats, and conduct multiple inspections to test the stability of the demodulation module. Generally, this time is relatively long, and the staff cannot always watch the TV. This way of media data is used to detect the continuous working effect of the demodulation module, which is too inefficient and requires a lot of labor. Contents of the invention [0003] In order to solve the above technical p...
