ABSTRACT:
A video disk player which can read two types of video disk. In the conventional video disk, analog audio channels are recorded in a frequency band between a digital audio channel and a video channel of a narrower bandwidth. In an advanced video disk, there is a digital audio channel and the video channel is extended downward to become adjacent to the digital audio channel. The disk player adjusts the lower frequency cut-off of a video band-pass filter in accordance with a detection of the type of disk, possibly by a special recorded code or by the detection of the analog audio carriers. Preferably, the video band-pass filter comprises a high-pass filter with an adjustable cut-off and a low-pass filter and the frequency-demodulator is positioned between these two filters.
