	Annex A
MEM	Multiplex Element Manager: A GUI-based control system, part of the
	range of Ericsson AB compression system control element products.
	The evolution 5000 MEM holds a model of the system hardware.
	Using this model, it controls the individual system elements to
	configure the output multiplexes from the incoming elementary
	streams. The MEM monitors the equipment status and controls any
	redundancy switching.
Meta-data	Meta-data is descriptive data that is "tagged" to a movie or audio
	clip. Meta-data is essential for the broadcaster.
MMDS	Multichannel Microwave Distribution System: A terrestrial microwave
	direct-to-home broadcast transmission system.
Motion	The use of motion vectors to improve the efficiency of the prediction
Compensation	of sample values. The prediction uses motion vectors to provide
	offsets into the past and/or future reference frames or fields
	containing previously decoded sample values that are used to form
	the prediction error signal.
Motion Estimation	The process of estimating motion vectors in the encoding process.
Motion Vector	A two-dimensional vector used for motion compensation that
	provides an offset from the coordinate position in the current picture
	or field to the coordinates in a reference frame or field.
MP@ML	Main Profile at Main Level: A subset of the MPEG-2 standard, which
	supports digital video storage (DVD etc.) and transmissions up to 15
	Mbps over various mediums.
MP@HL	Main Profile at High Level: A subset of the MPEG-2 standard, which
	supports digital video storage (DVD etc.) and transmissions up to 80
	Mbps over various mediums.
MPEG	Moving Pictures Experts Group: The name of the ISO/IEC working
	group which sets up the international standards for digital television
	source coding.
MPEG-2	Industry standard for video and audio source coding using
	compression and multiplexing techniques to minimise video signal
	bit rate in preparation for broadcasting. Specified in ISO/IEC 13818.
	The standard is split into layers and profiles defining bit rates and
	picture resolutions.
MPLS	Multi-protocol Label Switching. A Quality of Service mechanism for
	IP networks that allow IP packets to flow along a predefined path in
	a network, improving the reliability and robustness of the
	transmission.
MPTS	Multi-Program Transport Streams. Transport Streams that carry
	multiple TV/Radio services.
msb	Most significant bit.
Msymbol/s	(Msym/s) Mega (million) Symbols per second (106 Symbols per
	second).
Multiplex	A number of discrete data streams (typically 8 to 12), from
	encoders, that are compressed together in a single DVB compliant
	transport stream for delivery to a Modulator.
