Abstract
PURPOSE: To perform the narrow band delivery of color TV signal high in horizontal resolution, by expanding the sum of the low and high band components of luminance signal for the time axis, compressing the time for the low band component, decreasing the delivery band width, and inserting chromaticity signal and delivering it in vacant time.
CONSTITUTION: At the transmission side 11, the luminance signal Y from the signal source 12 is the sum signal between the low YL and high YH band components with the time axis expansion circuit 17, while the signal at the period in which the terminals 13 and 16 are connected is the component YL with time axis compression 19. The chromaticity signal is inserted to the vacant time produced by time axis compression for the signal consisting of the components of YL and YH of the signal Y, and it is delivered from the terminal 27. Further, at the reception side 29, the input signal is branched into two; one is made for the synchronous separation 32, producing control signal which controls the time axis compression circuit 35 and the time axis expansion circuit 36 etc, and other separates the signal arranged in time sharing and it is time-compressed, reproducing the signal Y and the chromaticity signal. Thus, the narrow band delivery of color TV signal having greater horizontal resolution can be made.
