Patent ID: 8019204

Claim:
A signal reproducing apparatus comprising: means for reproducing an encoding-resultant signal of a predetermined recording-medium format from a digital disc including a DVD, the encoding-resultant signal containing audio information resulting from quantization of an audio signal including a monaural channel audio signal at a quantization degree higher than a degree of quantization for a CD and at a quantization sampling frequency higher than that for a CD, the quantization sampling frequency including 96 kHz; means for decoding the reproduced encoding-resultant signal into a formatting-resultant signal corresponding to a predetermined format for a digital disc including a DVD, the formatting-resultant signal including segments corresponding to user data areas prescribed in the predetermined format, a compression-resultant-signal being placed in the segments of the formatting-resultant signal; means for deformatting the formatting-resultant signal into the compression-resultant signal; means for expanding the compression-resultant signal into a quantization-resultant signal by a Huffman decoding process; and an output circuit converting the quantization-resultant signal into the audio signal including the monaural channel audio signal.
