Abstract
PURPOSE: To reduce the transmission time as well as to increase the transmission efficiency by writing the output into the picture memory and the position data into the existence region memory at the time of the color component detection and then transmitting the output and the data along with the output of the memory which memorizes the white and black components to be received and demodulated.
CONSTITUTION: The input signal given through camera 1 undergoes D/A conversion 2 and then isolated 3 into the white/black and color components at transmitter side T. With detection of the color component via detector 13, the output is written into picture memory 5, and the position data to be written into memory 5 is written into existence region memory 14. The output of memory 5 and 14 are read out in sequence along with picture memory 4 memorizing the white/black component to be then transmitted. At receiver side R, the transmission signal is demodulated 8, and the white/black component and the color component are memorized in memory 9 and 10 respectively and then read out to undergo the D/A conversion and then to be displayed on TV monitor 11. Thus, the redundant color component is not transmitted, reducing the transmission time as well as increasing the transmission efficiency.
