Patent ID: 8422850

Claim:
An information transmitting apparatus comprising: a computer processor programmed to: convert content data, authored according to the DVD format and including a video signal, to a program stream by compression coding the content data into units of converting; divide the program stream into packs with a constant length which are units to be stored on a sector of a recording medium; perform error-correction coding on data of the divided packs by forming an error correction block from the predetermined number of sectors; and divide the error-correction coded data, which is arranged in an order for recording on a track of the recording medium, into units for storing in respective packets of a transport stream; and a transmitter for transmitting the transport stream in units of the packet through a network to an information recording apparatus capable of performing a recording operation on the recording medium; wherein: each of the units, into which the error-correction coded data is divided for storing in the respective packets of the transport stream, is set to be an error correction code word when the error correction block is formed and the error-correction coding is performed, the units of converting, into which the content data is converted, is set in such manner to allow an integer number of error correction clusters to be formed by the information recording apparatus from a predetermined number of consecutive packets after the transmitting, each of the units of converting follows control bytes in the packet, the sector group is formed by collecting the predetermined number of sectors, and a cluster-number of the error correction cluster for storing a leading sector of the sector group is stored in the control packet.
