Receiver for processing TV signals which have been transmitted according to the letterbox method.

摘要

This receiver exhibits a circuit for separating the luminance signal from the chrominance signals in accordance with the Colour-Plus method, a circuit for the vertical up-conversion of the luminance signal, a circuit for increasing the frame rate, a microcomputer for controlling the said circuits and a screen. According to the invention, common memory means are allocated to the said circuits and the arithmetics required for the vertical up-conversion of the luminance signal and for separating the luminance signal from the chrominance signals are arranged between the outputs of the common memory means and the screen.
