Embodiment Construction

[0039] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0040] The technical solution provided by the invention only backs up the navigable part in the DVD folder, but does not back up the unnavigable part in the DVD folder, so the backup speed is fast and the backup file takes up less space. Therefore, the technical solution provided by the invention has high backup efficiency, and can effectively utilize existing small-capacity DVD discs to complete the backup operation. The technical solutions of the present invention will be described in detail below in conjunction with the drawings and specific embodiments.

[0041] The invention provides a DVD ba...

Abstract

The invention relates to a DVD (digital video disk) technology and provides a DVD backup method, a DVD backup device and a DVD playing device, aiming at the defects of lower backup efficiency and easy excess of the capacity range of an ordinary DVD disk of a traditional DVD backup scheme because of the backup of all VTS (virtual terminal service) data. The DVD backup method comprises the steps of: reading and analyzing a DVD data packet for determining navigable DVD files in the DVD data packet and then backuping the navigable DVD files. The invention also provides a DVD backup device and a DVD playing device. The provided technical scheme is used for only backuping the navigable parts in a DVD folder rather than non-navigable parts in the DVD folder, thus the backup speed is fast and the space occupation of the backup files is small. Therefore, the provided technical scheme has high backup efficiency and can finish backup operation by effectively using a traditional DVD disk with small capacity.

Description

technical field [0001] The present invention relates to DVD technology, more specifically, relates to a DVD backup method, device and DVD playback device. Background technique [0002] The full name of DVD is "Digital Video Disc", that is, "Digital Video Disc". DVD discs are easily scratched during reading or saving, resulting in unsmooth playback. And DVD discs are relatively expensive, so it is necessary to back up the purchased DVDs. Because the optical drive is a slow input and output device, and the DVD capacity is relatively large, the time required for backup is longer and the space occupied is large. [0003] Existing DVD backup software, such as Xili Soft DVD Copy, Sly Soft CloneDVD, and Blaze DVDCopy, all copy all VTS (Video Title Set, video title set) data during the backup process. In the test of DVD video disc <<The Golden Compass>> ("Golden Compass"), <<StalloneRAMBO The Fight Continus>> ("The Last Drop of Blood"), etc., it is found t...
