[. . . ] DCT is not in itself a compression technique but is used to process the video data so that it is compressible by an encoder. DCT processes the picture on an 8x8-pixel block basis, converting the data from an uncompressible X Y form (as displayed by an oscilloscope) to a compressible frequency domain form (as displayed by a spectrum analyser). The unit containing the electronic circuitry necessary to decode encrypted signals. Some Decoders are separate from the receiver but in satellite TV broadcasting, the term is often used interchangeably as a name for an Integrated Receiver Decoder (IRD). The term IRD, or IRD / Decoder, is usually associated with satellite TV broadcasting while Cable systems are based on Converters or on Set-Top Boxes / Converters. A field that may be present in a PES packet header that indicates the time that an access unit is to be decoded in the system target Decoder. Method of coding using the difference between the value of a sample and a predicted value. Dual In Line: The most common type of package for small and medium scale integrated circuits. The pins hang vertically from the two long sides of the rectangular package, spaced at intervals of 0. 1 inch. Deutsches Institut fr Normung: German Standards Institute. The part of the satellite communications circuit that extends from the satellite to an Earth station. The process by which the frequency of a broadcast transport stream is shifted to a lower frequency range. Differential Pulse Code Modulation: An audio digitisation technique that codes the difference between samples rather than coding an absolute measurement at each sample point. Data circuit Terminating Equipment: A communications device that originates (is the source) or is the end receiving unit (destination) of signals on a network. The term used to describe uninterrupted transmission from the satellite directly to the subscriber, that is, no intermediary cable or terrestrial network utilised. Digital Video Broadcasting: A European project which has defined transmission standards for digital broadcasting systems using satellite (DVB-S), cable (DVB-C) and terrestrial (DVB-T) medium, created by the EP-DVB group and approved by the ITU. Specifies modulation, error correction, etc. (see EN 300 421 for satellite, EN 300 429 for cable and EN 300 744 for terrestrial). Digital Video Broadcasting Service Information. DVB-Professional Interfaces: TTV Lan search shows DVB Physical Interfaces Technical Earth: Ensures that all equipment chassis within a rack are at the same potential, usually by connecting a wire between the Technical earth terminal and a suitable point on the rack. This is sometimes known as a Functional earth. Protective Earth: Used for electric shock protection. [. . . ] If neither the Emergency nor Power-up Channel have been set, the TT1220 will be in an indeterminate state at power-up. E. 2. 3 Set Emergency Channel Sets the service to use in the event of a selection failure. It is activated after a specified time has elapsed. If not set, the Power-up Channel is assumed. Setting the Emergency Channel allows a failure situation to be recovered. E. 2. 4 Force Tune Carrier Forces the Receiver to retune to a different frequency and/or service. [. . . ]
