High-definition multimedia interface testing system and method

Abstract

The embodiment of the invention discloses a high-definition multimedia interface testing system and method. The high-definition multimedia interface testing system comprises a testing machine, a transmission interface, a high-definition multimedia interface signal conversion device and a computer; the transmission interface is connected with the testing machine so as to transmit an electrical signal; the high-definition multimedia interface signal conversion device is connected with the transmission interface so as to receive the electrical signal and convert the electrical signal into a digital signal; and the computer is connected with the high-definition multimedia interface signal conversion device so as to execute a testing program, wherein the testing program is used for judging whether the digital signal is matched with a pre-set signal value or not, and obtaining a testing result according to a judgement result. Thereby, the technical scheme in the embodiment of the invention has a fool-proof function; furthermore, a precise and effective testing result can be obtained; and simultaneously, the testing cost can be greatly reduced.

Description

technical field [0001] The invention relates to a test system, especially a high-definition multimedia interface test system and a test method thereof. Background technique [0002] Generally speaking, electronic products suitable for High Definition Multimedia Interface (HDMI), such as tablet computers, smart phones, notebook computers, and handheld game consoles, need to test high-definition multimedia interfaces during the manufacturing process. Whether the interface transmission function is normal is tested with a traditional high-definition multimedia interface test system. [0003] see figure 1 , which is a block diagram showing the architecture of a conventional high-definition multimedia interface testing system. In the traditional high-definition multimedia interface testing system 1 , the testing machine 11 is connected to the display 13 through a connection interface 12 , and the operator visually judges whether the picture displayed on the display 13 is normal....

AI Technical Summary

Problems solved by technology

However, since this method does not have the setting of the fool-proof function, it is easy to cause omissions due to the negligence of the operator, and it cannot be tested accurately and effectively. further affect the brand reputation, etc.

Simultaneously, it is necessary to purchase a display 13 for testing because of this testing method, so that the testing cost of electronic products remains high.
