Abstract

Considered Class B digital video channel is a kind of channel with gamut conversion, compression codec and other procedures, the conventional component video test signals are illegal and invalid when going through the Class B channel. In order to solve this problem, this paper studied the design principles applied to the component video test signals used for Class B digital video channels, and three kinds of standard definition test signals and one kind of high definition test signal used for the Class B digital video channel are designed with the parameters of the GY/T 243-2010 Standard-definition digital video TV channel technical requirements and methods of measurement, and these signals are implemented based on the Tektronix TG8000 multiformat test signal generator with XML language. Finally, a set of measurement experiments are performed with the test signals implemented in this paper.
