Dolby Authoring/Mastering Solutions for DVD and High-Definition Media
DVD is currently the leading consumer entertainment disc format. Every DVD player manufactured worldwide is equipped with Dolby® Digital decoding, and more DVD-Video titles are released in Dolby Digital than in any other audio format.
With the upcoming introduction of the HD DVD and Blu-ray Disc high-definition disc formats, consumers will have a choice of standard-definition and high-definition optical media for video and audio. Additionally, hard-disk-drive (HDD) media is being designed to accommodate high-definition programming.
Dolby audio technologies for these media represent the best choice for quality and market presentation. Dolby Digital is the established audio standard for all DVD media, and MLP Lossless™ is the standard for DVD-Audio. Dolby Digital Plus and Dolby TrueHD support the new HD media.
Here’s a quick guide to the Dolby technologies that are required in consumer disc media players. Content producers are free to choose from any of these formats, in any combination, for encoding, as long as they include at least one main soundtrack in a mandatory format for that disc media. This ensures that encoded discs will play on all consumer players.
Dolby Digital: Standard on DVD-Video, DVD-Audio, HD DVD, and Blu-ray Disc (up to 5.1 channels)
MLP Lossless: Standard on DVD-Audio (up to six channels)
Dolby Digital Plus: Standard on HD DVD, optional on Blu-ray Disc (up to 7.1 channels)
Dolby TrueHD: Standard on HD DVD, optional on Blu-ray Disc (up to 7.1 channels)
