Abstract:
In a television (TV) system, a double window processing apparatus, comprising:a first luminance/chrominance separation means for separating a combined image signal of a main image outputted from an intermediate frequency processing means into a luminance signal and a chrominance signal; a second luminance/chrominance separation means for separating the combined image signal of the main image and a combined image signal of a subimage outputted from the intermediate frequency processing means into a luminance signal and a chrominance signal, matching the synchronousnesses of the same, combining the synchronous matched luminance signal and chrominance signal and generating a double window luminance/chrominance signal; and a luminance/chrominance switching means for switching the luminance and chrominance signals of the first and second luminance/chrominance separation means in a double window mode and outputting one luminance and chrominance signal.
