Method for recording navigation information on a recording medium

Abstract

The present invention records A / V data and navigation information in a first format such as the DVD-Video format when a disk apparatus such as a DVD recorder performs a data recording operation. In the recording operation, the video object unit search information "VOBU_SRI" in the data search information "DSI" contained in the navigation information is recorded in a second format such as DVD+R or DVD+RW, thereby reducing the amount to be recorded on the optical disc. size of the navigation information.

Description

technical field [0001] The present invention relates to a method of recording navigation information on a recording medium such as an optical disc. Background technique [0002] In general, optical disc devices such as digital versatile disc (DVD) recorders capable of recording high-quality video data and high-quality audio data for a long period of time have been developed and put on the market and widely commercialized. For example, the DVD recorder shown in FIG. [0003] Meanwhile, the microcomputer 3 records audio and video (A / V) data input from the outside on the optical disc 10 by controlling the operation of the VDR system 12 based on a user's request. For example, the microcomputer 13 performs a series of data recording operations of encoding and processing A / V data in a preset DVD-Video format using the Moving Picture Experts Group (MPEG) method and then records it on an optical disk. [0004] In addition, the microcomputer 13 creates and records navigation inform...

Problems solved by technology

For this, for example, a memory of 32 megabytes higher than 18.43 megabytes is usually used, so there is a problem in that simplification of the hardware structure is hindered

So there is the problem of splitting a title limited to a maximum of 255 cells into multiple titles and recording multiple titles, whether the user intends to do so or not
