Patent ID: 8260123

Claim:
An information recording method by which data of a DVD content having been distributed from a source to a recording apparatus by way of a communications channel is recorded into a recording medium, comprising: obtaining, at the source, content that complies with the DVD format, dividing data of the obtained DVD content into a plurality of transport stream packets such that: the transport stream packets include the divided data of each sector of the obtained DVD content, and each of the transport stream packets include control bytes; and the control bytes include a content identification code that enables uniquely identifying the content, and a distribution-process identification code that enables individually identifying a content distribution-process, whereby the identification is made possible on a basis of the individual sectors for the DVD content, for the content and for the content distribution-process; providing at least one of a hard disk and a large-capacity optical disk as a possible selection for the recording medium; when the recording medium is selected to be a hard disk or a large-capacity optical disk, performing the following: correlating sectors for the DVD content with recording positions on the recording medium so that an integral number of error correction code blocks complying with the DVD format coincides with an integral number of units of error correction codes in the large-capacity optical disk, and adding to a predetermined area in the control bytes of the transport stream packets, the sector number of the individual sectors for the DVD content, and arrangement information for identifying the recording positions of the sectors on the recording medium; and recording, by the recording apparatus, the transport packets into the recording medium, wherein: the obtained DVD content is distributed by the source to the recording apparatus via the communications channel either before or after the dividing step is performed, and the information related to the recording positions are added to the predetermined area in the correlating control bytes.
