Abstract
A system for converting a digital component video signal having timing information contained therein to a digital composite video signal is described. The system has a decoder for extracting the timing information from the digital component signal, a digital memory means for storing portions of the desired digital composite signal, a memory control means for extracting the portions of said desired signal from the digital memory means in response to the timing information and a multiplexing means for combining the portions of the signal extracted from the digital memory in response to timing information of the digital component signal.
