DSP is also used in other parts of the video chain, including DVRs, and switching and routing devices. The transmission of a broadcast audio/video signal that consists of digital data. Converting analog audio and/or video into digital form. a) Qualitatively: Capacity for seeing distinctly fine details that have a very small angular separation. b) Quantitatively: Any of a number of measures of spatial visual resolution such as the reciprocal of the value of the angular separation in minutes of arc of two neighboring objects (points or lines or other specified stimuli) which the observer can just perceive to be separate. A generalized use class aspect that specifies what discrimination level you need to recognize a target of interest. See the Discrimination Level topic for video quality requirements considerations. a) The ultimate image presented to a viewer; the process of presenting that image. b) CRT, LCD, LED or other photoluminescent panel upon which numbers, characters, graphics or other data is presented. The deviation of the received signal waveform from that of the original transmitted waveform. A device that provides several isolated outputs from one looping or bridging input, and has a sufficiently high input impedance and input-to-output isolation to prevent loading of the input source. The difference between the maximum acceptable signal level and the minimum acceptable signal level. An acronym for "Digital Versatile Disk". It is the same size as a compact disc (CD). A single-layer DVD has a storage capacity of 4.7 GB and a dual-layer disc has a capacity of 8.5 GB. The signal used for the synchronizing of scanning specified in EIA Standards RS-170, RS-330, RS-343, or subsequent issues. An electronic circuit that introduces compensation for frequency discriminative effects of elements within the television system, particularly long coaxial transmission systems. The technology of transferring information, e.g., in communications or computer technology, through thin flexible glass or plastic tubes of optical fibers using modulated light waves. The extent to which an electronic device such as a stereo system or television accurately reproduces sound or images. a) In interlaced scan systems, the information for one picture is divided up into two fields. Each field contains one-half of the lines required to produce the entire picture. Adjacent lines in the picture are in alternate fields. b) Half of the horizontal lines (262.5 in NTSC and 312.5 in PAL) needed to create a complete picture. c) One complete vertical scan of an image.
