Techopedia Explains DTS-HD Master Audio

DTS-HD is the most common audio codec used for Blu-ray movies. When played on equipment using DTS Master Audio, it is a bit-for-bit lossless format. Otherwise, it is a lossy codec, where some information from a movie soundtrack is discarded. DTS-HD supports variable bit rates of up to 24.5 megabits per second in Blu-ray and 18 Mb per second on HD-DVD. The audio is transmitted over RCA or HDMI cables.
