1Digital signal processing — (DSP) is concerned with the representation of discrete time signals by a sequence of numbers or symbols and the processing of these signals. Digital signal processing and analog signal processing are subfields of signal processing. DSP includes… …
2Digital rights management — (DRM) is a term for access control technologies that are used by hardware manufacturers, publishers, copyright holders and individuals to limit the use of digital content and devices. The term is used to describe any technology that inhibits uses …
3Digital audio — Digital music redirects here. For a kind of modern music composed by digital means, see electronic music. A sound wave, in gray, represented digitally, in red (after quantization and zero order hold). Digital audio is sound reproduction using… …
4Digital video fingerprinting — Video fingerprinting is a technique in which software identifies, extracts and then compresses characteristic components of a video, enabling that video to be uniquely identified by its resultant “fingerprint”. Video fingerprinting is technology… …
5Data transmission — Data transmission, digital transmission, or digital communications is the physical transfer of data (a digital bit stream) over a point to point or point to multipoint communication channel. Examples of such channels are copper wires, optical… …
6Digital intermediate — (typically abbreviated to DI) is a motion picture finishing process which classically involves digitizing a motion picture and manipulating the color and other image characteristics. It often replaces or augments the photochemical timing process… …
7Digital video testing — in broadcast video, for example, is the process of validating and verifying that the video content and other data is being correctly processed, stored and transported. Despite the fact that the data is digital, most digital tv (DTV) system… …
8Video capture — is the process of converting an analog video signal such as that produced by a video camera or DVD player to digital form. The resulting digital data are referred to as a digital video stream , or more often, simply video stream . This is in… …
9Video coding — is the field in electrical engineering and computer science that deals with representation of video data, for storage and/or transmission, for both analog and digital video. Video coding is often considered to be only for natural video, it can… …
10Digital preservation — is the set of processes, activities and management of digital information over time to ensure its long term accessibility. The goal of digital preservation is to preserve materials resulting from digital reformatting, and particularly information …
