Patent ID: 7990418

Claim:
An automated test measurement system (ATMS), for automatically measuring a device under test (DUT), comprising: a control module, for receiving an encoder parameter and a test item, and generating a pattern command and an analyzer command according to the test item, wherein the control module comprises a receiving submodule, for receiving the encoder parameter and the test item; a signal generation module, for generating a pattern according to the pattern command; an encoder module, for transforming the pattern into a bitstream according to the encoder parameter, and transmitting the bitstream to the DUT, wherein the bitstream is then transformed into a test signal, wherein the encoder parameter comprises a video encoder parameter and an audio encoder parameter, the test item comprises a video test item, an audio test item, and test criteria values of the test items, the pattern command comprises a video pattern command and an audio pattern command, and the analyzer command comprises a video analyzer command and an audio analyzer command; and an analyzer module, for receiving the test signal from the DUT, and analyzing the test signal according to the analyzer command, wherein the control module further comprises a mapping table comprising a mapping relationship between the test items and the pattern, and a command generation submodule, for generating the video pattern command according to the video test item and the mapping table, generating the audio pattern command according to the audio test item and the mapping table, generating the video analyzer command according to the video test item, and generating the audio analyzer command according to the audio test item.
