	'''DTS-HD''' is a family of audio [[codec\|codecs]], primarily used in Blu-ray and HD-DVD – optionally, competing with the Dolby codecs family. It is an extension of the older [[DTS\|DTS Coherent Acoustics]] codec found in DVDs, and maintain compatibility with devices that only support those.		'''DTS-HD''' is a family of audio [[codec\|codecs]], primarily used in Blu-ray and HD-DVD – optionally, competing with the Dolby codecs family. It is an extension of the older [[DTS\|DTS Coherent Acoustics]] codec found in DVDs, and maintain compatibility with devices that only support those.

	* '''''DTS-HD Master Audio''''', previously known as DTS++, provides for lossless audio. It is a [[hybrid codec\|hybrid lossless/lossy]] codec with a "core" DTS CA stream, for devices only supporting that format, and a correction stream ~~called XLL~~. DTS-HD devices will decode both to reconstruct the signal losslessly. In Blu-ray it supports streams up to 192/24 at 5.1 surround, and up to 96/24 at 7.1 surround.		* '''''DTS-HD Master Audio''''', previously known as DTS++, provides for lossless audio. It is a [[hybrid codec\|hybrid lossless/lossy]] codec with a "core" DTS CA stream, for devices only supporting that format, and a correction stream specified in the DTS "Lossless Extension". DTS-HD devices will decode both to reconstruct the signal losslessly. In Blu-ray it supports streams up to 192/24 at 5.1 surround, and up to 96/24 at 7.1 surround.

	* '''''DTS-HD High Resolution''''' works a similar way with an extension stream, but is a lossy codec working at 6 kbit/s or 3 kbit/s constant bit rates (for use when disc space is a constraint). For example, the core stream can be 5.1 at 48 kHz sampling rate, and the extension stream can contain the additional two channels – and even doubling the sampling rate for the extra (inaudible!) ultrasonic octave.		* '''''DTS-HD High Resolution''''' works a similar way with an extension stream, but is a lossy codec working at 6 kbit/s or 3 kbit/s constant bit rates (for use when disc space is a constraint).
