Embodiment Construction

[0021] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0022] figure 1 is a structural diagram of an HDMI interface test fixture in an embodiment, such as figure 1 As shown, the test fixture includes: an HDMI interface unit 100 , a TV brand (or model) parameter unit 200 and a control unit 300 . The HDMI interface unit 100 is connected to the HDMI interface of the set-top box through an HDMI cable. The control unit 300 is used to write the parameters of each brand of TVs into the TV brand parameter unit 200 to perform a compatibility test. After the HDMI interface unit 100 is connected with the HDMI interface of the set-top box, the TV parameters wri...

Abstract

The invention relates to an HDMI interface testing clamp and method. TV HDMI interfaces are made independent, and the parameters of TVs of various brands are separately written in a TV brand parameter unit via a control unit to simulate the TVs of different brands for testing; as a result, the TVs of a plurality of brands are not required so that the testing cost can be greatly reduced; besides, the case that an HDMI wire is plugged out and in repeatedly and connected to different TVs is also avoided; the HDMI interface testing clamp is simple and convenient to operate and greatly convenient for testing.

Description

technical field [0001] The invention relates to the communication field, in particular to an HDMI interface test fixture and a test method. Background technique [0002] With the popularization of high-definition digital TV, the HDMI interface (high-definition media interface) with high-definition output capability has gradually become a necessary interface for high-definition set-top boxes, and the requirements for the reliability of HDMI interface design are also getting higher and higher. [0003] Because the HDMI interface of the set-top box needs to be connected with the TV, and there are many brands of TVs, there are differences between different brands of TVs. The set-top box may have no output or abnormal output on the HDMI interface of a certain brand of TV, which indicates that the HDMI interface output of the set-top box is not compatible with the TV of this brand, which will greatly affect the normal use of the set-top box. In order to ensure that the set-top bo...
