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.
