Abstract
Methods of testing receiver video fidelity are disclosed. One example method includes producing a video test signal; coupling the video test signal into an input of the receiver, wherein the video test signal is configured to cause a decoder to output a step function signal upon processing the video test signal; coupling the step function signal to a display rate converter; and measuring signal characteristics of signals provided at a receiver output.
