DTS-HD is an audio coding technology developed by DTS and targeted for the HD generation of optical discs (namely [[Blu-Ray]] and [[HD-DVD]]). The technology specification embodies various coding modes and extensions to the [[DTS]] core.

	DTS-HD ~~contains a normal [[~~DTS]] core~~. There's always one~~ DTS core		DTS-HD frames may either extend DTS core (then they will follow each DTS core frame) or form an independent stream of DTS-HD frames only. In the former case DTS-HD frame may contain some extensions to the core frame (e.g. XBR for the additional resolution, XXCh for the additional channels or even XLL for reconstructing the original audio bit-perfectly). Independent DTS-HD frames may contain several streams internally, for example core audio (with possible extensions signalled explicitly), DTS-HD Master Audio (lossless audio) or DTS Express (a low-bitrate codec related to [[QDesign Music Codec]]).

DTS-HD is an audio coding technology developed by DTS and targeted for the HD generation of optical discs (namely [[Blu-Ray]] and [[HD-DVD]]). The technology specification embodies various modes and extensions, one of which is XLL, an extension for lossless audio coding.

			DTS-HD contains a normal [DTS] core. There's always one DTS core
			package and then one DTS-HD package. Then again one DTS core
			package and then again one DTS-HD package.

			The DTS-HD packages begin with the text "dX %", which is in hex
			"64 58 20 25". There's a length field in the DTS-HD package which
			tells you how long the DTS-HD package is exactly. If you skip this
			length, you should end up on the next DTS core package. The
			length of the DTS-HD package is stored in the bytes 6-8. The lowest
			four bits of the sixth bytes are the most significant bits of the length
			field. All 8 bits of the seventh byte are used for the length field. And
			the 3 most significant bits of the eightth byte are the least significant
			bits of the length field. Finally you need to add 1 to the length field.
			So the length calculates like "(sixthByte & 0xf) << 11 + seventhByte
			<< 3 + (eightthByte >> 5) & 7 + 1".

			DTS-HD can be either DTS-HD High Resolution (lossy, constant
			bit rate) or DTS-HD Master Audio (lossless, variable bit rate).
			Obviously DTS-HD High Resolution packages in a specific DTS-HD
			stream always have the same size. While DTS-HD Master Audio
			packages vary in size. But the size field in the DTS-HD package
			is always set correctly, so you don't really need to worry about
			High Resolution vs. Master Audio.

			Skipping over full DTS-HD packages is much better

			word could theoretically also occur inside of a DTS-HD package.
