Abstract: Methods, systems and software are disclosed for automated Measurement of Video Quality parameters. The system includes a static Test Pattern provided either in form of a Test Pattern File, converted via a standard playout device (test source) into analog or digital test signal and supplied to the input of a System Under Test, or in form of a Reflectance Chart installed before the front-end device of the System Under Test, such as TV camera. The system also includes a video capture device connected to the back-end device of the System Under Test, e.g. to the output of system decoder/player. A Video Quality Analyzer processes the captured video data and generates a detailed Analysis Report.

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.
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.
