Abstract

PURPOSE: To ensure the easy writing of the characters featuring the clear contours by generating the characters to be written through the character generator and then mixing these characters with the video signals.
CONSTITUTION: The device consists of synchronous control circuit 2, microprocessor 3, character generator 6, keyboard 4 and others. Then the information on the size, type, color, etc. of the character is supplied through keyboard 4, and thus processor 3 secures the necessary memory range at memory 5. After this, the writing character is supplied through keyboard 4 and then memorized in memory 5. When the editing is over, change-over switch 10 is switched toward (c). And the reproduction of video tape recorder 1 is performed at the output side of video mixer 7. At the same time, the command is generated from keyboard 4 when the writing is desired. Then the character picture signal is supplied to video mixer 7 from generator 6 in the form of the series signal and in agreement with the synchronous signal of circuit 2. The picture signal is then mixed with the video signal at mixer 7 to be picture-recorded newly through video tap recorder 8.
