Digital Command Control (DCC) is a standard for a system for the digital operation of model railways that permits locomotives on the same electrical section of track to be independently controlled. The DCC protocol is defined by the Digital Command Control Working group of the US National Model Railroad Association (NMRA).

Display Data Channel (DDC) is a collection of protocols for digital communication between a computer display and a graphics adapter that enable the display to communicate its supported display modes to the adapter and that enable the computer host to adjust monitor parameters, such as brightness and contrast.
Encoding schemes 8b/10b have found a heavy use in digital audio storage applications, namely Digital Audio Tape, US Patent 4,456,905, June 1984 by K. Odaka. Digital Compact Cassette (DCC), US Patent 4,620,311, October 1986 by Kees Schouhamer Immink. A differing but related scheme is used for audio CDs and CD-ROMs:
In information theory, data compression, source coding, [1] or bit-rate reduction is the process of encoding information using fewer bits than the original representation. [2] Any particular compression is either lossy or lossless. Lossless compression reduces bits by identifying and eliminating statistical redundancy. No information is lost in ...
In order to include these missing characters the 16-bit UTF-16 (in GSM called UCS-2) encoding may be used at the price of reducing the length of a (non-segmented) message from 160 to 70 characters. The messages in Chinese, Korean or Japanese languages must be encoded using the UTF-16 character encoding. The same was also true for other ...
DCC CHAT is normally initiated using a CTCP handshake. The user wishing to establish the connection sends the following CTCP to the target, DCC CHAT protocol ip port, where ip and port are the IP address and port number of the sender, and are expressed as integers. protocol is chat for standard DCC CHAT. The receiving party can then connect to ...
The Philips DCC-822/DCC-824 car stereo with DCC player had a full dot-matrix text display which could display upper-case and lower-case characters on prerecorded tapes as well as user-recorded tapes. Later-generation portable recorders DCC-170 and DCC-175 were capable of displaying text information from prerecorded tapes, but not from user ...
