Brief Technical Glossary
HDMI – High Definition Multimedia Interface
Digital interface for digital video and audio data transmission (preferred for HDTV).
HDTV – High Definition Television
High resolution television with a resolution up to 5 times higher or finer than PAL or NTSC. However, there is no compatibility, as the transmission process
The principal features of HDTV are the larger picture format (16:9), the doubled number of scanning lines (increased from the currently 625 to 1,250) and digital sound quality.
High band
Satellite frequency range between 11.7 GHz and 12.75 GHz.
H.264
Another designation for
LNB - Low Noise Block Converter
Converts the satellite downlink frequencies into the
Low band
Satellite frequency range between 10.7 GHz and 11.7 GHz.
MPEG-2
MPEG is the abbreviation for Moving Picture Experts Group, a working group that formulates internationally applicable standards for the digital compression of video and audio.

Personal Identification Number. For this unit the PIN is a
QAM - Quadrature-Amplitude-Modulation
Digital modulation process with phase shift keying, which is used for transmissions in cable networks.
QPSK - Quadrature Phase Shift Keying
Digital modulation process that is used for satellite transmission (8PSK is also used in connection with HDTV).
Receivers
Satellite receiver

Symbol Rate
The symbol rate describes the quantity of data that is transmitted per second. The symbol rate is measured in MSymbols/s and is equal to the number of symbols received per second.
