Abstract

The invention provides a set top box with an external USB module. The set top box comprises a set top box mainboard, a power supply module, a front control panel, an AV terminal, a relay module and a relay control circuit. The power supply module is electrically connected with the set top box mainboard. The front control panel is electrically connected with the set top box mainboard. The input end of the AV terminal is electrically connected with slave equipment. The moving contact of the relay module is electrically connected with the input end of the AV terminal and the set top box mainboard respectively. Slave equipment AV signal input and switching can be rapidly and conveniently realized.

Description

technical field [0001] The invention specifically relates to a set-top box with an external USB module. Background technique [0002] Production testing of set-top box products is mainly based on interface testing and functional testing. The interface of the set-top box mainly includes: coaxial cable input, high-definition video output HDMI port, AV video output port, analog audio output port, USB host interface, network port. Common set-top box interface testing methods are: a. The coaxial input port is connected to the coaxial cable, and the signal generator sends out audio and video streams. The tester sets the set-top box to the corresponding frequency point of the signal generator, searches for the corresponding video signal, and the set-top box After decoding the audio and video stream, the tester judges whether the video signal is normal; Normal; c. Insert a U disk into the USB interface, and the tester manually copies the file to the U disk to judge whether the fil...
