DiSEqC (Digital Satellite Equipment Control) A DiSEqC compatible receiver relies on a switching box which detects the 22kHz tone pulsing rapidly on and off. In this way, a specially designed receiver can control numerous LNBs through a DiSEqC switching box. Dolby Digital An encoding system that digitally compresses up to 5.1 discrete channels of audio (left front, centre, right front, left surround, right surround) into a single Bitstream. A low frequency effect (LFE) channel is included providing the sound needed for special effects. DVB (Digital Video Broadcasting) Set of standards that define digital broadcasts using satellite, cable or terrestrial systems. EPG (Electronic Programme Guide) An electronic equivalent to a printed television listings magazine; it is an application used with digital settop boxes and digital television sets to list current and scheduled programs that are or will be available on each channel, including a short summary or commentary for each program. The information supplied in the EPG is sent and updated by the channel broadcaster. FEC (Forward Error Correction) A technique for error control of data transmission. Frequency The property of a signal measured in cycles per second (=Hz). FTA (Free- To-Air) An unscrambled broadcaster allowing customers to view channels or services without paying any subscription.

HDMI (High-Definition Multimedia Interface) An all-digital audio/video interface that supports standard, enhanced, or high-definition video, plus multi-channel digital audio on a single cable. It transmits all ATSC HDTV standards and supports 8-channel digital audio. Hi-Fi (High Fidelity) The characteristics of audio devices that can play back all the audio frequencies a person can detect, which is the range of 16Hz-20KHz. Sometimes it is used to indicate good quality of audio devices such as stereo tape recorders. LNB (Low Noise Block) A device that is mounted on an arm facing your satellite dish, focusing on satellite signals. A LNB converts signals received from satellite to a lower frequency and sends them to a satellite receiver via coaxial cable. NVOD (Near Video On Demand) A technology that allows customers to view the start of popular programmes or films within a short period from the time they make their selection. This is possible as the broadcaster sends multiple copies with staggered start times. OSD (On Screen Display) OSD displays the basic information necessary for the users to configure monitor or TV settings.
