  • Patent number: 7254456
    Abstract: A data arranging method for linear PCM data, which allows both low cost and high cost machines to easily perform a reproduction process and can cope with multiple channels. Data having a structure in which each sample data of 20 bits or 24 bits of individual channels is separated to a main word consisting of 16 bits and an extra word consisting of 4 or 8 bits, a collection of 2n-th main words of the individual channels is arranged, a collection of (2n+1)-th main words of the individual channels is then arranged, a collection of 2n-th extra words of the individual channels is then arranged, and a collection of (2n+1)-th extra words of the individual channels is then arranged, is recorded on a recording medium or transferred.

  • Patent number: 5953375
    Abstract: Audio data at the top of each packet is always set at the top of sample data, thereby allowing packets to be treated as units and facilitating audio data processing, such as timing processes, sequential processing, etc. A plurality of samples consisting of variable length data are arranged in a packet of predetermined bytes. In one embodiment, all samples other than the first sample are sequentially arranged with the top of the first sample being disposed at a predetermined position of the packet. The total byte length of the sample data is less than or equal to a maximum packet byte length If the actual packet byte length is less than the maximum packet byte length, stuffing byte data or a padding byte data is inserted to fill in a remaining portion.
