5.1 ("five point one") is the common name for six channel surround sound multichannel audio systems. 5.1 is now the most commonly used layout in both commercial cinemas and home theaters. It uses five full bandwidth channels and one low frequency enhancement channel (the "point one"). Dolby Digital, Dolby Pro Logic II, DTS, and SDDS are all commonly 5.1 systems. 5.1 is also the standard surround sound audio component of digital broadcast and music.
All 5.1 systems use the same speaker channels and configuration, having a front left and right, a center channel, and two surround channels.
Blu-ray and Digital cinema both have eight-channel capability which can be used to provide either 5.1 or 7.1 surround sound. 7.1 is an extension of 5.1 that uses four surround zones: two at the sides and two at the back.
7.1 ("seven point one") surround sound is the common name for eight channel surround audio systems. It adds two additional speakers to the more conventional six channel (5.1) audio configuration. 7.1 surround sound positional audio uses the standard front, center, and LFE (bass) speaker configuration. In its most common configuration, 7.1 surround sound includes two speakers positioned to the side and two to the rear. 7.1 surround sound can also refer to 5.1 surround sound configurations with the addition of two front height channels positioned above the front channels or two front wide channels positioned between the front and surround channels.
The Blu-ray Disc and the HD DVD home video formats provide up to 8 channels of lossless DTS-HD Master Audio, Dolby TrueHD or uncompressed LPCM audio at 96 kHz/24-bit. The Sony PlayStation 3 video-game console can output up to 7.1 LPCM through HDMI for both Blu-ray movies and games.
