DTS-HD Master Audio
From Wikipedia, the free encyclopedia
DTS-HD Master Audio is a lossless audio codec created by Digital Theater System. It was previously known as DTS++ and DTS-HD. It is an extension of DTS which, when played back on devices which do not support the Master Audio extension, degrades to a 1.5 Mbit/s "core" track which is lossy. DTS-HD Master Audio is an optional audio format for both Blu-ray Disc and HD DVD.
One goal of the DTS-HD Master Audio format was to allow a bit-for-bit representation of the original movie's studio master soundtrack. To accomplish this, DTS-HD MA supports variable bit rates up to 24.5 Mbit/s on a Blu-ray Disc and up to 18.0 Mbit/s for HD-DVD. There is support for a 96kHz sampling frequency and 24-bit depth samples in up to 8 channels for both disc formats.
