Abstract
PURPOSE: To reduce the limit for the picture process time by installing to the TV picture receiver the means which projects the different compressed TV signal at part of the TV video screen plus the means which gives the time division to the synchronous signals via the external or internal synchronous signal respectively.
CONSTITUTION: The signal of ecannel CHA selected through tuner 2 undergoes the detection and amplification and is then supplied to signal selection circuit 13 in the form of video signal P. The signal of CHB selected through tuner 6 undergoes the detection and amplification to be supplied to control circuit 20 via signal generation circuit 23. Circuit 20 samples and memorizes the video signal of CHB and then read out in the double speed as high as the sampling and memorization to be then supplied to circuit 13 after compression of the time axis to 1/2. Circuit 13 selects the video signal and combines the video signals of CHA and CHB together to deliver them. Circuit 23 gives the synchronous isolation to the video signal of CHB and then converts the signal into the signal composed of N-unit of low and high-level picture elements in a horizontal scanning period and with use of the synchronous- isolated signal or the signal given from outside. Then the synchronous signal is added to the converted signal to form the output video signal, thus ectending the process time for one picture element.
