segments of video information, and to a method and apparatus
for reproducing information from a disc which has data
recorded thereon of a type which includes a frame of a video
signal which is displayed while an audio portion is played.
Claims 42 and 45 are illustrative of the claimed
invention, and they read as follows:
42. An apparatus for producing a signal used for forming
a record disc which stores segments of audio information and
corresponding segments of video information, comprising:
means for receiving a video signal to be recorded and an
audio signal to be recorded;
a memory for storing said audio signal during recording;
a video normalizer, receiving an output of said memory,
and adjusting a level of said output of said memory to produce
a normalized signal which is adjusted relative to a level of
said video signal, thereby utilizing a full dynamic range of
video circuitry; and
means for combining said normalized signal indicative of
audio with said video signal to produce a composite normalized
signal.
45. An apparatus for reproducing information from a disc
which has data recorded thereon of a type which includes a
frame of a video signal which is displayed while an audio
portion is played, comprising:
an element which scans said disc to obtain a combined
video/data signal, said video/data signal having a video
portion and an audio portion normalized relative to said video
portion;
