– A Dolby digital audio encoding scheme. The audio encoding format adopted by the ATSC. 

ATSC 

Advanced Television Systems Committee 

BER 

Bit Error Rate - The number of erroneous bits divided by the total number of bits over a stipulated period of 

time. Usually expressed as a number and a power of 10. 

Bit 

An indivisible unit of digital data represented as 1 or 0. 

bps 

Bits per second 

Broadcast 

A service that is delivered to all subscribers. Each subscriber may select a particular broadcast channel 

out of many. 

Byte 

An octet of associated bits 

Cable 

Cable Television Systems 

Carrier 

An RF signal used to carry information (video, audio, data) by some modulation scheme. 

Coax 

Coaxial Cable 

Composite video 

A baseband representation of a video signal containing luminance and chrominance information. 

C/N 

Carrier to Noise Ratio 

dB 

Decibel - A logarithmic value of a ratio 

dBc 

Decibels relative to carrier amplitude 

dBm 

Decibels relative to one milliwatt 

dBmV 

Decibels relative to one millivolt across a given impedance (75 ohms in North American cable systems) 

DTV 

Digital Television 

– A general term for the digital coding and transmission of an Audio / Video Program. 

EIA

Headend 

The control center of a cable television system, where incoming signals are amplified, converted, 

processed, and combined into a common cable, along with any locally originated programming, for transmission to 

subscribers. 

HRC 

Harmonically Related Carrier 

IF 

Intermediate Frequency. A signal processing stage between RF and baseband. 

IP 

The network layer (layer 3) of the OSI Internet protocol, providing connectionless datagram service. 

IRC

kHz 

Kilohertz - Cycles per second, in thousands 

Mbps 

Megabits per second- bits per second in Millions 

MHz 

Megahertz - Cycles per second, in Millions 

MPEG 

Moving Picture Experts Group - An international standards-setting group, working to develop standards for 

compressed full-motion video, audio, and other associated information. 

MPEG-2 

Refers to multiple parts of the ISO/IEC 13818 standard
