摘要： A high definition television (HDTV) for displaying an image contained in a broadcasting signal of mutually different broadcasting systems is provided. The HDTV restores a first image signal which is an image signal contained in an HD digital broadcasting signal and a second image signal which is an image signal contained in an NTSC analog broadcasting signal which are input from an antenna and an external input port, and format-converts each restored image signal into an image signal having a predetermined frame format. An image signal synthesizer including two memories and a timing signal generator time-base-compresses the format-converted first and second image signals so as to correspond to a main picture and a sub-picture of a PIP image to be displayed, and synthesizes the first and second image signals into a single PIP image signal. A CRT displays a PIP image contained in the PIP image signal on a screen.

摘要： A video signal processing system includes a circuit for detecting the delay between a luminance signal and a color signal in a video signal, and for automatically compensating for the delay. The circuit includes a Y/C separator for separating a composite video signal into the luminance signal and the color signal, and a color difference and synchronous signals separator for separating the luminance and color signals into synchronous and color difference signals. A delay circuit receives and delays the luminance signal based on a delay control signal, and outputs the delayed luminance signal to a video signal processor, which also receives the color difference signals directly from the color difference and synchronous signals separator. The delay control signal is generated by a delay correction signal generator, which is responsive to the synchronous signals generated by the color difference and synchronous signals separator, and outputs of the video signal processor, including a delayed luminance signal and color difference signals. The delay correction signal generator 22 reciprocally compares the luminance signal with the color signals in accordance with the separated synchronous signals, and outputs the delay control signal, corresponding to the detected amount of delay, to the delay circuit, in order to delay the luminance signal, and thereby compensate for the delay between the color signals and luminance signal.
