Abstract

A format converting unit includes a data analysis unit for analyzing the data configuration of each pack, a data obtaining unit for obtaining data in each process, a checking unit for checking data, an RDI data obtaining unit for obtaining predetermined RDI data, a first arithmetic process unit for converting time information, a second arithmetic process unit for performing a PES extension deleting process, a third arithmetic process unit for performing an audio pack converting process, and an arithmetic unit and a second buffer for converting RDI data into a navi-pack. The unit converts the format of the data in the video recording system into one in the video system.

Description

field of invention [0001] The present invention relates to the technical fields of an information recording device, an information recording method, and an information recording program, and more specifically, relates to a format conversion device for recording information. Background technique [0002] Recently, among popularized data compression methods, there is a tendency to use a large-capacity optical disc and an optical disc for recording an entire movie or the like called DVD (Digital Versatile Disc). [0003] A typical recording system for recording information on movies and the like (hereinafter referred to as content information) on a large-capacity optical disc may be a video system compatible with the read-only DVD format, or a video system that is not compatible with the read-only DVD format but uses The recorded content information can be easily edited to be suitable for a video recording system that records data in real time on an optical disc. [0004] Vide...
