Abstract: PURPOSE: To take synchronism of 1/2 horizontal frequency oscillator with a simple circuit, by re-insertion of burst signal delayed by a given amount.  
     CONSTITUTION: The burst pick up circuit 7 picks up the burst signal from the subtraction output of the addition and subtraction circuit 4, this is delayed for a given amount by the delay circuit 9, and it is re-inserted to the delay burst signal carrier chrominance signal at the addition circuit 2. Next, the switch 10 alternately picks up the re-inserted burst signal inserted to the addition circuit 2 and the re-insertion burst signal delayed at the 1H delay circuit 3, and the both outputs are added at the addition circuits 14 and 15. The inserted position of the re-insertion burst signal at the addition output is picked up and detected at the burst detection circuit 13 and the detected output controls the polarity of the rectangular wave output. Thus, the synchronism of the 1/2 horizontal frequency oscillator can be taken.
