The left and right surround speakers in the bottom line create the surround sound effect. 5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres. [1] It uses five full bandwidth channels and one low-frequency effects channel (the "point one"). [2]
7.1 channel surround is another setup, most commonly used in large cinemas, that is compatible with 5.1 surround, though it is not stated in the ITU-standards. 7.1 channel surround adds two additional channels, center-left (CL) and center-right (CR) to the 5.1 surround setup, with the speakers situated 15 degrees off centre from the listener.

Dolby Atmos in theaters has a 9.1 (commonly referred to as 7.1.2) channel-based "bed" channels for ambience stems or center dialogue, leaving 118 tracks for objects. [16] Atmos for home in film, television, and music uses a technique called "spatial coding" to reduce the audio to up to a maximum of 16 concurrent "elements" or audio location ...
Wireless LAN (WLAN) channels are frequently accessed using IEEE 802.11 protocols. The 802.11 standard provides several radio frequency bands for use in Wi-Fi communications, each divided into a multitude of channels numbered at 5 MHz spacing (except in the 45/60 GHz band, where they are 0.54/1.08/2.16 GHz apart) between the centre frequency of the channel.
Previous HDMI versions use three data channels (each operating at up to 6.0 Gbit/s in HDMI 2.0, or up to 3.4 Gbit/s in HDMI 1.4), with an additional channel for the TMDS clock signal, which runs at a fraction of the data channel speed (one tenth the speed, or up to 340 MHz, for signaling rates up to 3.4 Gbit/s; one fortieth the speed, or up to ...
The amount of inter-channel interference seen on a configuration using channels 1, 5, 9, and 13 (which is permitted in Europe, but not in North America) is barely different from a three-channel configuration, but with an entire extra channel. [94] [95] 802.11 non-overlapping channels in the 2.4 GHz ISM band
Program-specific information. Program-specific information (PSI) is metadata about a program (channel) and part of an MPEG transport stream. The PSI data as defined by ISO/IEC 13818-1 (MPEG-2 Part 1: Systems) includes four tables: The MPEG-2 specification does not specify the format of the CAT and NIT. PSI is carried in the form of a table ...
The internal storage of the PlayStation 5 is a custom-built 825 GB solid-state drive (667 GB available) [48] with a 12-channel interface, achieving a raw throughput of 5.5 GB/s. This atypical drive size was found to be optimal for the 12-channel pathway rather than a more common 512 GB or 1 TB unit.
