High-dense light disk document forming method and playing method and recording player thereof

Abstract

The invention relates to high density compact disc file constructive method and its playing method and recording player. It includes the following steps: respectively recording AV flow and relative many subheads flow with the independent file; the AV flow is managed by playing order; the subhead flow is managed by sub playing order whose maximum quantity is designed preliminarily. The invention can offer the playing management information of the recorded auxiliary data and the subhead playing to make the subhead playing of the high density compact disc more effective.

Description

technical field [0001] The present invention relates to a file composition method including playback management information for effectively playing main data and auxiliary data recorded in an optical disc, and in particular to providing subtitle information as auxiliary data and playing back on high-density optical discs such as Blu-ray discs The playing method and the invention of the recording and playing device thereof. Background technique [0002] As an optical recording medium, an optical disc is widely used because it can record a large amount of data. Recently, a new type of high-density optical recording medium (HD-DVD) capable of recording high-quality video data and high-quality audio data for a long period of time has been developed, such as a Blu-ray Disc (hereinafter referred to as "BD"). [0003] As a replacement technology of HD-DVD, Blu-ray Disc (BD) is currently developing a standard technology sample worldwide together with other digital devices because i...

AI Technical Summary

Problems solved by technology

[0006] However, in the current Blu-ray Disc specifications, there is no uniform specification for the auxiliary data - especially the subtitle information.

Therefore, in fact, there are still many constraints in developing an optical recording and playback device based on a perfect Blu-ray disc.
