Abstract

The invention discloses a method and system for testing audio and video of a set-top-box, and relates to the technical field of test. The problem of complex structures of the test systems of the existing network access audio and video is solved. The main system comprises a digital TV signal source used for sending a digital TV signal; a to-be-tested set-top-box connected with the digital TV signal source; an audio and video measurement instrument and an infrared remote control module connected with the to-be-tested set-top-box respectively, wherein the audio and video measurement instrument is used for testing an audio and video signal sent by the to-be-tested set-top-box, and the infrared remote control module is used for transmitting an infrared signal to control the to-be-tested set-top-box; the audio and video measurement instrument is connected with a controller, and the controller is used for receiving a test result of the audio and video signal output by the audio and video measurement instrument; and the infrared remote control module is connected with a controller, and the controller is used for sending a control instruction to the infrared remote control module. The method and system disclosed by the invention are mainly applied to a 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...
