Embodiment Construction

[0041] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation manners of the present invention will now be described in detail with reference to the accompanying drawings.

[0042] see figure 1 It is a flow chart of the testing method of the audio and video output interface in the embodiment of the present invention. Include the following steps:

[0043] S1. Receive and parse the test file from the audio and video output interface to be tested to obtain phoneme data and / or videometa data.

[0044] The audio and video output interface to be tested is the audio and video output interface of the device to be tested. When the device to be tested needs to be tested, the test file is played (for example, played in a loop) on the device to be tested. Therefore, the test file can be received from the audio and video output interface of the device under test.

[0045] In the embodiment of the pr...

Abstract

The invention discloses test equipment and a test method for an audio and video output interface. The test equipment comprises an audio and video input interface, a receiving module, a solving module and a test module which are connected in sequence, wherein the audio and video input interface is connected with the to-be-tested audio and video output interface of to-be-tested equipment. The test equipment and the test method have the beneficial effects that high expandability and high automatic degree are realized; a test process can be finished rapidly and accurately without manual intervention; analog audio and video interfaces as well as digital and encrypted audio and video interfaces can be tested; test results can be displayed intuitively and conveniently.

Description

technical field [0001] The invention relates to the field of testing, more specifically, to a testing device and a testing method for an audio and video output interface. Background technique [0002] Audio and video output is one of the most basic functions of a set-top box. In order to ensure the factory quality of the set-top box, the audio and video output interface of the set-top box must be tested during the production process of the set-top box, so as to avoid the failure of the set-top box to leave the factory due to hardware failure of the audio and video output interface. [0003] On the other hand, with the improvement of people's living standards and the continuous improvement of people's requirements for the output quality of audio and video equipment, there will be more and more audio and video equipment in the family. In order to enable the set-top box to better match the audio and video equipment in the home, there will be more and more audio and video outpu...
