MPE
A PID which can contain anything.
MPEG
Moving Picture Experts Group. A joint working group of the International Standards
Organization and International Electrotechnical Committee. Some portions of the MPEG
Standards have also been prepared jointly with the ITU-T.
MPEG-1
A family of specifications developed originally for compression of low-resolution (SIF) video at
24-, 25-, and 30-Hz frame rates with associated audio. At these resolutions, 1.5 Mbps audio and
video data can be stored on a standard compact disk (CD).
MPEG-2
A family of specifications developed originally for compression of studio television at
24-, 25-, and 30-Hz frame rates. The system layer has support for additional functionality,
including tolerance to errors, which makes it generally more suitable for transmission than
MPEG-1.
MPEG-4
A family of specifications developed originally for video games. The original video coding
specification has been supplanted by AVC, MPEG-4 Part 10 (also known as H.264), which
provides significant compression efficiencies over MPEG-2 video coding. Also includes AAC/
HE AAC audio coding specifications.
MPTS
Multiple Program Transport Stream. Several MPEG programs multiplexed together into a single
Transport Stream.
MSMQ
Microsoft Message Queue.
Multimode fiber
Optical fiber designed to carry multiple light rays or modes concurrently each at a lightly different
reflection angle within the optical fiber core. Multimode fiber transmission is used for relatively
short distances because the modes tend to disperse over longer lengths. For longer distances,
singlemode fiber is used.
multiplex
The ability to combine multiple signals over a single communications line or channel.
multiplex
A function where multiple signals are combined into a single signal. A device that merges several
lower-speed transmissions into one high-speed transmission, and vice versa. See also
Note that multiplexing functionality is usually built into encoders.
