Abstract
PURPOSE: To eliminate a color shift of a reproduced picture by removing in stability of initial reproduction of a picture frame following a sound frame, by inserting a color burst signal into a back porch of the horizontal blanking part of a frame carrying sound information.
CONSTITUTION: Synchronizing with synchronizing pulses from synchronizing pulse generating circuit 1, pickup tube 3 is driven to apply the output of pickup tube 3 to mixer 6 through gate 4 and it is mixed into an output from burst signal generating circuit 9 and then supplied as a color video signal to change-over circuit 10. A signal from sound signal generating circuit 11 is stored in buffer memory 12 and the sound signal is time-compressed synchronizing with a synchronizing signal from trigger generating circuit 13 and then supplid to mixer 15. Then, synchronizing pulses and a color burst signal are mixed in the sound signal, a video format signal carrying sound information is supplied to change-over circuit 10, and the color video signal and format signal from change-over circuit 10 are supplied, desired frames by frames, to signal processing circuit 16 by turns.
