Abstract

A flexible digital video simulator has been constructed so that the effects of image coding and compression can be observed and evaluated in real time. This paper describes the design of the simulator's digitizer which includes the analog-to-digital (A/D) converter, the digital-to-analog (D/A) converter, and the programmable clock synthesizer. Although this system is presently being used for processing National Television Systems Committee (NTSC) composite video signals, it can be reconfigured for processing other image transmission formats. Examples include red, green, and blue (RGB) component signals, luminance and chrominance (YIQ) signals, and enhanced-definition television (EDTV) signals.
