ABSTRACT:
The high-definition RGB television signal is converted on one side into a normal-definition color TV signal according to a chosen current standard (NTSC, PAL or SECAM), and on the other into a high-definition color TV signal slowed to a frame frequency which is a submultiple of the original scanning value, and the two color TV signals are transmitted on two independent earth TV channels or on a satellite channel. In reception, said normal-definition signal is converted into a first TV signal with a scanning frequency matching that of high definition, and said slowed high-definition color signal is converted into a second high-definition signal having its original frequency, and said first converted signal and said second converted signal are applied to a high-definition TV display respectively for the moving portions of the picture and for the fixed portions of the picture.
