EPG
Electronic Program Guide is a digital guide to scheduled broadcast television or
radio programs, typically displayed on-screen with functions allowing a viewer to
navigate, select, and discover content by time, title, channel, genre, etc. by use of
their remote control, a keyboard, or other input devices such as a phone keypad.
Content can also be scheduled for future recording by a personal video recorder
(PVR).The on-screen information may be delivered by a dedicated channel or
assembled by the receiving equipment from information sent by each program
channel.
FEC
Stands for Forward Error Correction. This is a system of error control for data
transmission, whereby the sender adds redundant data to its messages, also
known as an error-correction code. This allows the receiver to detect and correct
errors (within some bound) without the need to ask the sender for additional data.
The advantages of forward error correction are that a back-channel is not
required and retransmission of data can often be avoided (at the cost of higher
bandwidth requirements, on average).
HDMI
Stands for High-Definition Multimedia Interface. It is a compact audio/video
interface for transmitting uncompressed digital data. HDMI connects digital audio/
video sources—such as set-top boxes, Blu-ray Disc players, personal computers
(PCs), video game consoles (such as the PlayStation 3 and some models of
Xbox 360), and AV receivers—to compatible digital audio devices, computer
monitors, and digital televisions. As an uncompressed connection, HDMI is
independent of the various digital television standards used by individual devices,
such as ATSC and DVB, as these are encapsulations of compressed MPEG
video streams (which can be decoded and output as an uncompressed video
stream on HDMI).
LNB
Stands for Low-Noise Block converter. This is the (receiving, or downlink)
antenna of what is commonly called the parabolic satellite dish commonly used
for satellite TV reception. The LNB is usually fixed on or in the satellite dish. The
purpose of the LNB is to take a wide block (or band) of relatively high frequencies,
amplify and convert them to similar signals carried at a much lower frequency
(called intermediate frequency or IF).These lower frequencies travel through
cables with much less attenuation of the signal, so there is much more signal left
on the satellite receiver end of the cable. It is also much easier and cheaper to
design electronic circuits to operate at these lower frequencies, rather than the
very high frequencies of satellite transmission.
PID
Stands for Packet Identifier. This is a set of numbers identifying stream packets
contained within a single data stream
Polarization
The orientation of the electrical and magnetic fields of a signal. Satellites use
mainly vertical and horizontal polarization.
S/PDIF
Stands for Sony/Philips Digital Interconnect Format. A common use for the
S/PDIF interface is to carry compressed digital audio as defined by the standard
IEC 61937.This mode is used to connect the output of a DVD player to a home
