Filed: 2004-03-22
Abstract: <P>PROBLEM TO BE SOLVED: To output an input video signal while shaping in any one of video format or transmission format of communication system hierarchy.  <P>SOLUTION: One of input signals distributed to two systems by a distributor 141 is inputted to a selector 142 and the other is inputted to a communication CDR 143. The communication CDR 143 shapes an input video signal and generates a lock signal in case of communication system format as well as generates a nonlock signal.
