Abstract
Systems and methods are disclosed to perform automated audio visual (AV) delay measurement for a system under test (SUT) by generating a dynamic AV test pattern to drive a source display device and one or more destination video display devices; detecting video output through at least one light sensor coupled to the one or more destination video display devices; digitizing the light sensor output; and performing multi-channel delay parameters analysis.
Claims8
A method to perform automated audio visual (AV) delay measurement for a system under test (SUT), comprising:
- a. generating a dynamic AV test pattern to drive a source display device and one or more destination video display devices;
- b. detecting video output through at least one light sensor coupled to the one or more destination video display devices;
- c. digitizing the light sensor output;
- d. performing multi-channel delay parameters analysis;
- and
- e. grouping audio and video input into pairs of video inputs and pairs of audio inputs, each pair having one Reference Point and one Test Point to provide independent determination of video latency or audio latency value per pair.
