摘要： A data transmission system for transmitting information data with a parity of an error correcting code for correcting an error in the information data. A read-out controller controls a transmitter to transmit information data and a parity so that each data component of the information data obtained by dividing the information data of one data block area into a plurality of data components and each parity component of the parity obtained by dividing the parity of one block area into a plurality of parity components are transmitted at intervals of each sector having a sector address. The sector is defined as an data area obtained by dividing one data block area of a predetermined data amount into a plurality of sectors each having an identical data amount.

摘要： When, through a multi-speaker of a DVD audio system, signals are recorded/reproduced using a sampling frequency different for every channel, the quantity of calculation of a filter circuit is reduced. Up-sampling information about whether or not the sampling is carried out before the up-sampling by up-sampling means (2a, 2b) is acquired by up-sampling information detecting means (6). The signal up-sampled is filtered by a halfband filter circuit (3), subjected to loss-less compression, and recorded on a recording medium (8).

摘要： An information storing disk including at least one system stream stored thereon. The at least one system stream includes a silent cell for defining a silent period and an audio cell for defining audio data to be reproduced after the silent period. The silent period is a period to be silent, which is from when one system stream to be reproduced among at least one system stream is determined until reproduction of an audio cell included in the one system stream is started.

摘要： In an optical disk, data are recorded by using a hierarchical file structure in which a frame is composed of digitized data, a packet is composed of at least one frame, and a pack is composed of at least one packet. In this structure, the pack is composed of an integral number of packets, each packet being completed, and each of the packets is composed of an integral number of frames, each frame being completed. Therefore, there is no possibility that one frame is assigned over two or more different packets and one packet is assigned over two or more different packs. Since an integral number of frames are assigned in each packet, when a packet header is detected, reproduction of data can be carried out from the beginning of each packet.

摘要： A method and apparatus for descrambling data that is characterized by shift registers that realize an operation of generating polynomial and that have a ring-shaped structure that realizes plural and continuous operation. The method and apparatus further includes an initial value setting means for setting initial values in m shift registers; after setting the initial values, shifting the initial values while synchronizing the initial values with input clocks, and outputting the exclusive OR of data which is input while being synchronized with clocks and the lowermost latch outputs. Scrambled data with a byte is treated as a unit by using an exclusive OR circuit block.
