Abstract

The present application discloses a method and system for testing audio and video of a set-top box, which relate to the technical field of testing, and are intended to solve the problem of complex structure of the existing network-connected audio and video testing system. The main system includes: a digital TV signal source for sending digital TV signals; a set-top box to be tested connected to the digital TV signal source; an audio and video measuring instrument and an infrared remote control module respectively connected to the set-top box to be tested, the audio and video The video measuring instrument is used to test the audio and video signals sent by the set-top box to be tested, and the infrared remote control module is used to transmit infrared signals to control the set-top box to be tested; the audio and video measuring instrument is connected to the controller, and the controller is used for The test result of the audio and video signal output by the audio and video measuring instrument is received; the infrared remote control module is connected with the controller, and the controller is further configured to send a control instruction to the infrared remote control module. The present application is mainly applied in the process of testing the set-top box.

Description

technical field [0001] The present application relates to the technical field of testing, in particular to a method and system for testing audio and video of a set-top box. Background technique [0002] In order to be able to watch live satellite TV, a set-top box is installed on the TV to receive live satellite signals through the set-top box. The basic function of the set-top box is to receive digital TV broadcast programs, and at the same time have all broadcast and interactive multimedia application functions. The main key technologies for the set-top box to receive digital TV broadcast programs include: channel decoding, new source decoding, embedded CPU (Central Processing Unit, central processing unit), MPEG-2 decompression, software, display control and scrambling and descrambling technology, etc. . [0003] For the set-top box network access test, follow the technical standards of the radio and television industry GY / T 278-2014 "Technical Requirements and Measurem...
