The term often is confused with copy protection and technical protection measures. These two terms refer to technologies that control or restrict the use and access of digital media content on electronic devices with such technologies installed, acting as components of a DRM design.

Digital Transmission Content Protection over Internet Protocol (DTCPIP) is a specification for copy protection of copyrighted content that is transferred over digital interfaces in home networks that adhere to IP. Under this specification, digital content can be shared securely between devices in a user’s home but not shared with third-parties outside the home network. Using an authentication scheme, DTCP-IP allows the user to designate devices in the home network as trusted destinations that can transfer data back and forth, but DTCP-IP will not allow the content to be transmitted over the Internet to be shared outside of the home network.

Digital Video Broadcasting (DVB) is a suite of internationally accepted, open standards for digital television maintained by the DVB Project, an industry consortium with more than 270 members, and published by a Joint Technical Committee (JTC) of European Telecommunications Standards Institute (ETSI), European Committee for Electrotechnical Standardization (CENELEC) and European Broadcasting Union (EBU).

HyperText Transfer Protocol (HTTP) is a request/response protocol between clients and servers. The originating client, such as a web browser, spider, or other end-user tool, is referred to as the user agent. The destination server, which stores or creates resources such as HTML files and images, is called the origin server. In between the user agent and origin server may be several intermediaries, such as proxies, gateways, and tunnels.

Internet Radio is a broadcasting service transmitted via the Internet. Not every internet "radio station" has a corresponding traditional radio station. Many internet radio stations are completely independent from traditional ("terrestrial") radio stations and broadcast only on the Internet. Broadcasting on the Internet is usually referred to as streaming.

Set-Top Box connects to a television and some external source of signal, and turns the signal into content then displayed on the screen. The signal source might be an ethernet cable, a satellite dish, a coaxial cable, a telephone line, or even an ordinary VHF or UHF antenna. Content, in this context, could mean any or all of video, audio, Internet webpages, interactive games, or other possibilities. A set-top box does not necessarily contain a tuner of its own.

Streaming Media is media that is heard or viewed while it is being delivered. Streaming is more a property of the delivery system than the medium itself. The distinction is usually applied to media that are distributed over computer networks by streaming or file transfer; most other delivery systems are either inherently streaming (radio, television) or inherently non-streaming (books, video cassettes, audio CDs).
