AI Technical Summary

Problems solved by technology

Much of this slow rate is due to the nature of the mechanical components of conventional DVD devices and limitations regarding reading and especially writing data to the disc
Therefore, the traditional special effects used to achieve copy, delete and undelete functions on magnetic media may not be suitable for DVD

Embodiment Construction

[0027] Detailed description of the preferred embodiment

[0028] Recordable DVD device

[0029] The device 100 that realizes various advanced operating functions according to the solution of the present invention demonstrated here uses figure 1 The block diagram shows the rewritable disk medium 102 according to the scheme of the present invention. Rewritable disc media 102 is used as a rewritable DVD in the illustrated embodiment. In many of the examples described subsequently, the rewritable disk medium may also be, for example, a hard disk or a magneto-optical disk (MOD). An example of a MOD is a minidisc. In many instances, the solutions of the present invention can be applied to video or audio or both.

[0030] Device 100 can write to and read from disk media, which in this example is a rewritable DVD 102 . The device includes a mechanical assembly 104 , a control portion 120 , a video / audio input processing path 140 and a v...

Abstract

Method and apparatus for editing a recorded series of bits on a rewritable disc media. The method includes the steps of selectively identifying a beginning point and an end point of a segment of the recorded series of bits to be deleted; and modifying a first jump command in a control data portion of the disc. The first jump command is modified for causing playback from the disc to continue at the end point when reading in a forward direction. The method can further include modifying a second jump command in a control date portion of the disc for causing playback from the disc to continue at the beginning point when reading data for playback in a reverse direction.

Description

technical field [0001] The present invention generally relates to a method and apparatus for providing advanced operational functionality to audio programs, video programs, and audio and video programs recorded on disc media such as recordable digital video discs, hard disk drives, and magneto-optical discs. Background technique [0002] Various devices have been developed that enable customers to record video and / or audio programs for later playback. Such devices include tape recorders, video cassette recorders, recordable compact discs, and most commonly, recordable digital video discs (DVDs). Hard disk drives and magneto-optical disks are also used. [0003] A record-once DVD is essentially a DVD read-only memory, acronym DVD-R. The acronym DVD-R can also generally refer to a write-once, or record-once technology. Several formats are available for recording, erasing or re-recording of DVDs; ie overwriting or rewriting. These are denoted by t...
