MCPC

Multiple Channel Per carrier. DTH satellite TV programmers use a transmission format called Multiple Channel Per Carrier to multiplex two or more program services into a single unified digital bit stream. With MCPC, a package of program services can use the same conditional access and forward error correction systems, thereby economizing on the overall bandwidth and transmission speed requirements.

Microwave

The frequency range from approximately 500 MegaHertz (MHz) to 30 GigaHertz (GHz).

Modem

MOdulator-DEModulator. A device that adapts a terminal or computer to a telephone line converting the computer’s digital pulses into audio frequencies (analog) for the telephone system and converts the frequencies back into digital pulses at the receiving side.

Modulation

The alteration of a carrier wave in relation to the value of the data being transferred. Analogue satellite transmission use FM modulation . Digital satellite transmission use QPSK modulation.

MPE

Multi Protocol Encapsulation.

MPEG

Moving Pictures Experts Group. A proposed International standards organisation (IS) standard for digital video and audio compression for moving images.

Multicast

A special form of broadcast where copies of the packet are delivered to only a subset of all possible destinations.

Network

An interconnection of computer systems, terminals, or data-communications facilities.

NTP

Network Time Protocol. Protocol built on top of TCP that assures accurate local time- keeping with reference to radio and atomic clocks located on the Internet. (see RFC 1305).

Packet

A sequence of data, with associated control information, that is switched and transmitted as a whole.

PES

Packetized elementary stream (MPEG elementary stream after packetization).

PID

Packet Identifier (PES identification number in the DVB standard).

Pixel

The smallest element or dot on a video-display screen.
