Abstract

The invention provides a method for storing data of a DVD video disc, its playback method and its playback device. Wherein, the method for storing data of a DVD video disc is to store audio-video data files of a MPEG program stream in a DVD physical disc, and store a pointer file in the said DVD physical disc. The file name of the said pointer file is to indicate the DVD physical disc which store audio-video data files of a MPEG program stream. The method can store large-scale audio-video data in a standard DVD disc, and make the standard DVD disc be DVD video disc of large capacity. The playback method and the playback device of the DVD video disc are able to play the DVD audio-video disc with large capacity, which make the playing time of audio-studio data in a standard DVD disc greatly extended, and reduce the cost of producing and manufacturing long-playing video programs.

Description

A kind of DVD video disc date storage method, player method and playing device

Technical field

The present invention relates to the storage and the play-back technology of DVD video disc, is a kind of DVD video disc date storage method, player method and playing device concretely.

Background technology

At present, be tending towards ripe gradually based on the DVD player of dvd pickup pick-up and MPEG1/2 decoder and DVD platform technology, yet DVD disc of the prior art still exists some shortcomings, its concrete manifestation is:

One, the DVD-VIDEO disc adopts the MPEG-2 coding techniques at present, generally only can store on the DVD of a single-surface single-layer and can play 135 minutes audio, video data; For such as long-time audio/video programs such as educational programme, TV series, Kara OK songs, just must it can be stored by many DVD discs like this.This has just increased the DVD dish makes, produces and the cost of circulation, and to the use of DVD dish, carry, keeping brings inconvenience;

Two, along with the popularizing of VCD machine and DVD player, the VCD program of having issued on the market is innumerable, yet these VCD program source are transferred to that capacity is bigger, cost is lower DVD disc gets on but is a thing that is difficult to accomplish to desire.This obviously is the waste to VCD program resource, has also limited the diversity of DVD program making simultaneously.

Summary of the invention

The objective of the invention is to, a kind of DVD video disc date storage method, player method and playing device are provided.Wherein: a kind of DVD video disc date storage method can be stored the audio, video data of super scale on a standard DVD video disc, make the DVD video disc of standard become vast capacity DVD video disc; Described DVD video disc data playing method and playing device then are method and the devices that above-mentioned vast capacity DVD video disc can be play.Thereby make the reproduction time of the audio, video data on a standard DVD video disc, stored prolong greatly, and reduced the making and the production cost of long video frequency program; It also can make the existing VCD program source of having issued in the market transfer to easily on the DVD disc carrier, and does not need the special-purpose software of making, thereby has reduced DVD program making cost, the source of also having enriched the DVD program simultaneously.DVD video disc data replay apparatus wherein also can be play common DVD video disc.

This case of technological invention of the present invention is:
