DVD-VR

1. 본문

DVD-VR, which stands for DVD Video Recording, is a recordable DVD format introduced in 1999 by the DVD Forum. It's a format designed for video recording on DVD-R, DVD-RW, and DVD-RAM discs, including dual-layer versions.

Here are some of the key features and aspects of DVD-VR:

• Editing Capabilities: DVD-VR offers extensive editing features directly on the disc, without needing a PC. These include:
• Frame-accurate editing: Splitting, deleting, and partially deleting titles.
• Adding chapters and bookmarks.
• Creating playlists to define different playback paths.
• Space Management: DVD-VR can automatically reuse freed-up space on a disc. When a title is deleted, the space becomes available for new recordings.
• Time-Slip: This feature allows for the simultaneous recording and playback of content, with a slight delay.
• Bilingual Broadcasting: It supports recording bilingual broadcasts (Main/Sub language) and allows selection during playback.
• Mixed Content: Video and data files (like digital pictures) can be combined on a single disc.
• Multiple Titles: It allows recording up to 99 titles per disc.
• Technical Details:
• Video is recorded as an MPEG program stream.
• Supports multiple audio encodings, including MPEG Audio, Dolby Digital (AC-3), and linear PCM.

• Compatibility: DVD-VR is *not* DVD-Video compliant, meaning discs recorded in this format may not play back on all DVD players. DVD+VR, on the other hand, is designed for greater compatibility with standard DVD players.
• Supported Media: DVD-VR is used with DVD-R, DVD-RW, and DVD-RAM media. DVD+VR is intended for DVD+R and DVD+RW media.
• Space management: DVD-VR uses fragmented recording. All unused disc space can be randomly added to new recordings, as opposed to DVD+VR's tape-model.

• Editing: DVD-VR offers on-disc editing features, unlike the standard DVD-Video mode.
• Compatibility: DVD-Video mode creates discs playable on almost all DVD players, while DVD-VR has compatibility limitations.
• Finalization: Discs recorded in DVD-Video mode usually need to be finalized before they can be played on other players. With DVD-VR, you can often eject a disc without finalizing and continue recording later, though this depends on the player's capabilities.
