Patent ID: 7254456

Claim:
A recording medium on which processed quantized data obtained by sampling one channel or multi-channel signals in a time sequential manner is recorded and reproduced, wherein: said data recorded on said recording medium has a form in which M-bit sample data of each channel signal is separated into a main word consisting of m1 bits on an MSB(Most Significant Bit) side and an extra word consisting of m2 bits on an LSB(Least Significant Bit) side, a collection of main words of 2n-th sample data of individual channels is arranged as a main sample S2n1 a collection of main words of (2n+1)-th sample data of individual channels is arranged next as a main sample S2n+1, a collection of extra words of 2n-th sample data of individual channels is then arranged as an extra sample e2n, and collection of extra words of (2n+1)-th sample e2n+1 (where n=0,1,2, . . . ), said data is a collection of said main samples S2n, S2n+1 and said extra samples e2n, e2n+1 as an unit, a frame is formed by a collection of a predetermined number of samples and is assigned to one or more audio packets which are arranged, mixed with video packets and sub picture packets, between control packets, each of said packets has a predetermined byte length, when a plurality of main and extra samples are arranged in each of said one or more audio packets, a top of a first main sample is placed at a predetermined position in each of said one or more audio packets and other samples are sequentially arranged after said first main sample, a total byte length of said plurality of main and extra samples is equal to or smaller than a maximum byte length of each of said one or more audio packets, when said total byte length is less than said maximum byte length, invalid data of a stuffing byte or a padding packet is inserted in a remaining portion, and a pack includes a pack header, a packet and, a packet header, said packet header is attached to a data section in which said sample data is stored in each pack, said packet header includes at least a first access unit pointer, quantization bit data, a sampling frequency, and channel information regarding the quantized data, a pack header is attached to said packet header, said pack header includes information representing a stuffing length.
