The 10BROAD36 broadband variant of Ethernet was standardized by 1985, but was not commercially successful.[8][9] The DOCSIS standard became available to consumers in the late 1990s, to provide Internet access to cable television residential customers. Matters were further confused by the fact that the 10PASS-TS standard for Ethernet ratified in 2008 used DSL technology, and both cable and DSL modems often have Ethernet connectors on them.
Power lines have also been used for various types of data communication. Although some systems for remote control are based on narrowband signaling, modern high-speed systems use broadband signaling to achieve very high data rates. One example is the ITU-T G.hn standard, which provides a way to create a local area network up to 1 Gigabit/s (which is considered high-speed as of 2014) using existing home wiring (including power lines, but also phone lines and coaxial cables).
In video[edit]
"Broadband" in analog video distribution is traditionally used to refer to systems such as cable television, where the individual channels are modulated on carriers at fixed frequencies.[10] In this context, baseband is the term's antonym, referring to a single channel of analog video, typically in composite form with separate baseband audio.[11] The act of demodulating converts broadband video to baseband video. Fiber optic allows the signal to be transmitted farther without being repeated. Cable companies use a hybrid system using fiber to transmit the signal to neighborhoods and then changes the signal from light to radio frequency to be transmitted to over coaxial cable to homes. Doing so reduces the use of having multiple head ends. A head end gathers all the information from the local cable networks and movie channels and then feeds the information into the system.
However, "broadband video" in the context of streaming Internet video has come to mean video files that have bitrates high enough to require broadband Internet access for viewing.
"Broadband video" is also sometimes used to describe IPTV Video on demand.[12]
