Abstract
A system to perform automated audio visual (AV) delay measurement for a system under test (SUT) includes a test pattern generator to generate a dynamic AV test pattern and connected to a source display device and to one or more destination video display devices; at least one light sensor coupled to the one or more destination video display devices; an AV capture device having video inputs connected to the light sensors; and an AV delay analyzer coupled to the AV capture device to perform multi-channel delay parameters analysis.
