ABSTRACT:
A method for testing the chroma performance of a digital rendering integrated circuit includes generating a video test signal where the video test signal has a constant luma amplitude, constant chroma amplitude, and varying chroma phase. The method then continues by modulating the video test signal with the digital rendering circuit, and displaying output from the digital rendering circuit.
