Embodiment Construction

[0018] In order to fully understand the present invention, preferred embodiments thereof will be described below with reference to the accompanying drawings.

[0019] figure 1 is a block diagram of an apparatus for manufacturing a read-only optical disc on which navigation data according to the present invention is recorded. The device includes: a laser diode 10 for generating a laser beam; a collimator 11 for collimating the generated laser beam; The optical modulator 13 of the parallel light beam of collimator 11; Be used for focusing the light beam from optical modulator 13 on the light sensitive layer (for example, photoresist material) that is positioned at the condenser lens 14 on glass substrate; Be used for input content data encoding An encoder 20 into MPEG format; a formatter 21 for formatting encoded data into ECC block data for recording; a high-capacity storage medium 23 (for example, a hard disk drive) for storing data; A disk read / write unit 22 for reading / wri...

Abstract

A structure of navigation information for video data recorded on a recording medium and recording / reproducing methods and apparatuses using the structure. A primary data stream and secondary data streams associated with the primary data stream are recorded on a recording medium and access management information such as TMAP information is created for each of the recorded data streams and recordedthereon, the access management information including type information indicating whether the corresponding data stream is a primary stream or a secondary stream.

Description

technical field [0001] This document relates to a structure of navigation information of a read-only recording medium on which a main stream and a sub stream are recorded, and a recording / reproducing method and apparatus using the structure. Background technique [0002] A DVD-ROM, generally called a DVD, has a storage capacity of 4.7 GB, and is generally used as a storage medium for delivering high-quality digital content such as movies. [0003] Television stations broadcast both analogue and digital today, but in the not-too-distant future only digital TV broadcasts will be available. Digital broadcasts offer better video quality than their analog counterparts. Audiences naturally want to enjoy movies with higher video quality than DVD. [0004] For this reason, read-only discs with a higher storage capacity than DVDs are being developed. Higher-capacity discs can provide viewers with high-quality content in more diverse ways. For example, higher capacity discs can pr...
