(optional) DTS Digital Surround - format used for DVDs, 5.1-channel surround sound.
(mandatory) DTS-HD High Resolution Audio - extension of DTS, 7.1-channel surround sound.
The Internet connection will only be needed for value-added features such as downloading new extras, watching recent movie trailers, web browsing, etc.
It will also be required to authorize managed copies of Blu-ray movies that can be transferred over a home network.
SMPTE VC-1 - standard based on Microsoft's Windows Media Video (WMV) technology.
Please note that this simply means that all Blu-ray players and recorders will have to support playback of these video codecs, it will still be up to the movie studios to decide which video codec(s) they use for their releases.
The following formats are part of the Blu-ray Disc specification: BD-ROM - read-only format for distribution of HD movies, games, software, etc.
How fast can you read/write data on a Blu-ray disc? Blu-ray also has the potential for much higher speeds, as a result of the larger numerical aperture (NA) adopted by Blu-ray Disc.
The format offers more than five times the storage capacity of traditional DVDs and can hold up to 25GB on a single-layer disc and 50GB on a dual-layer disc.
The format was developed to enable recording, rewriting and playback of high-definition video (HD), as well as storing large amounts of data.
However, as BD-ROM movies will require a 54Mbps data transfer rate the minimum speed we're expecting to see is 2x (72Mbps).
There's also plans for a BD/DVD hybrid format, which combines Blu-ray and DVD on the same disc so that it can be played in both Blu-ray players and DVD players. According to the Blu-ray Disc specification, 1x speed is defined as 36Mbps.
(optional) DTS-HD Master Audio - lossless encoding of up to 8 channels of audio.
