Abstract:
A signal recording apparatus comprising:means for quantizing an input audio signal into a quantization resultant-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;means for compressing the quantization-resultant signal into a compression-resultant signal by a Huffman encoding process;means for formatting the compression-resultant signal into a formatting-resultant signal corresponding to a predetermined format for a DVD, the formatting-resultant signal including segments corresponding to user data areas prescribed in the predetermined format, the compression-resultant signal being placed in the segments of the formatting-resultant signal;means for encoding the formatting-resultant signal into an encoding-resultant signal of a predetermined recording-medium format; andmeans for recording the encoding-resultant signal on a DVD.
