CVBS (Composite Video Baseband Signal)
A technology for transmitting video signals via a cable. Mixes luminance (brightness) and the chrominance (colour)
signals together.
DiSEqC (Digital Satellite Equipment Control)
A DiSEqC compatible receiver relies on a switching box which detects the 22kHz tone pulsing rapidly on and o. 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 eect (LFE) channel is included providing the sound
needed for special eects.
DVB (Digital Video Broadcasting)
Set of standards that dene 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 set-top 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.
HDD (Hard Disk Drive)
The primary computer storage medium, which is made of one or more aluminum or glass platters, coated with a
ferromagnetic material.
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 lms 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 congure monitor or TV settings. OSD information may
include brightness, contrast, tuning, RGB adjustment, and screen size and position.
OTA (Over the Air)
A standard for the transmission of software for equipment, through a broadcast system. Manufacturers reserve the right
for deciding the release of the software for their products.
PID (Packet Identier)
A set of numbers identifying stream packets contained within a single data stream.
PIP (Picture In Picture)
A function that allows you to display two dierent TV channels (or TV inputs) on a single screen.
