Abstract
PURPOSE: To discriminate easily the contents of a color video format signal by inserting color bursts, differing in the number of cycles, into motion-picture frames and still-picture frames.
CONSTITUTION: Video signals from pickup tube 3, blanking signals and synchronizing-pulse color burst signals are mixed by mixer 36 and applied to switching part 11. Under the control of timing circuit 7 receiving signals from assignment part 8, gate circuit 9 inserts corresponding color bursts, differing in the number of cycles, into back porches of horizontal blanking parts of motion-picture and still-picture frames. Sound signals, after being time-compressed by gate 15, are mixed with synchronizing signals are have video format signals converted. Video and sound signals are recorded on recording medium 19 by way of switching part 11. In reproduction, fixed formats are easily discriminated by inserted bursts to perform reproduction control.
