ITU-R International Telecommunications Union - Radio.
Formerly CCIR. Deals with the standardization of wireless communication.
ITU-T International Telecommunications Union - Telecommunications.
Formerly CCITT. Produces global telecommunication standards, and
defines tariff and accounting principles.
Joint Stereo An audio mode in which the left and right channels of audio are encoded
into one channel. This mode is used to reduce bandwidth needs, and thus
improve compression efficiency.
JPEG Joint Photographic Experts Group.
Name of the committee that created the JPEG standard (and also other
standards). The JPEG standard specifies the codec, which defines how a
still image is compressed into a stream of bytes and decompressed back
into an image.
JVT Joint Video Team (JVT).
The Joint Video Team is a group of video coding experts from ITU-T Study
Group 16 (VCEG) and ISO/IEC JTC 1 SC 29 / WG 11 (MPEG) created to
develop an advanced video coding specification. The JVT’s main result has
been ITU-T Rec. H.264 | ISO/IEC 14496-10, commonly referred to as
H.264/MPEG-4-AVC, H.264/AVC, or MPEG-4 Part 10 AVC.
kbit/s Kilo bits per second.
LAN Local Area Network.
A local area network is a network that connects computers and devices in
a limited geographical area such as home, school, computer laboratory or
office building.
LATM Low-overhead Audio Transport Multiplex.
LATM is part of the method to encapsulate HE-AAC audio into transport
stream.
LC-AAC Low Complexity-Advanced Audio Coding.
LCD Liquid Crystal Display.
LED Light Emitting Diode.
LOAS Low-overhead Audio Stream
LOAS is part of the method to encapsulate HE-AAC audio into a transport
stream.
M In a GOP (Group Of Picture), M is the distance between successive
P-Frames.
Macroblock A area of the TV picture. Macroblocks are usually composed of two or
more blocks of pixels. The size of a block depends on the codec and is
usually a multiple of 4. In MPEG-2 the size is fixed at blocks of 8x8 pixels.
In H264 the overarching macroblock size is fixed at 16x16 pixels, but this is
broken down into smaller blocks or partitions which are either 4, 8, 12 or
16 pixels by 4, 8, 12 or 16 pixels.
MBAFF MacroBlock Adaptive Frame Field coding. Use a macroblock pair structure
for pictures coded as frames.
Mbit/s Million bits per second.
