Integrated Services Digital Broadcasting Terrestrial (ISDB-T)
Japanese standard for digital terrestrial television. The modulation
method used is OFDM. The baseband signal is an MPEG-2 transport
stream.
ITU-T J83
Collection of various standards for digital television over broadband ca-
ble.
J83A = DVB-C
J83B = North American standard for digital television over broadband
cable (64QAM, 256QAM).
J83C = Japanese standard for digital television over broadband cable (6-
MHz variant of DVB-C)
J83D = ATSC variant for digital television over broadband cable
(16VSB); not used.
Low Density Priority Check Code
Block code used in the FEC of the DVB-S2 satellite transmission stan-
dard.
Low Voltage Differential Signalling (LVDS)
LVDS is used for the parallel interface of the transport stream. It is a
positive differential logic. The difference voltage is 330 mV into 100 Ω.
Master Guide Table (MGT)
MGT is a reference table for all other PSIP tables (ATSC). It lists the
version number, the table length and the PID for each PSIP table with the
exception of the STT. MGT is always transmitted with a
Section in the PID 0x1FFB and indicated by the table_ID=0xC7.
Main Profile at Main Level (MP@ML)
MP@ML is a type of source coding for video signals. The profile de-
termines the source coding methods that may be used while the level de-
fines the picture resolution.
Megaframe Initialization Packet (MIP)
The MIP is transmitted with the PID of 0x15 in transport streams of ter-
restrial single frequency networks (SFNs) and is defined by DVB. The
MIP contains timing information for GPS (Global Positioning System) and
modulation parameters. Each megaframe contains exactly one MIP. A
megaframe consists of n TS packets, n being dependent on the modulation
parameters. The transmission period of a megaframe is about 0.5 seconds.
Moving Picture Experts Group (MPEG)
MPEG is an international standardization committee working on the
coding, transmission and recording of (moving) pictures and sound.
MPEG-2
MPEG-2 is a standard consisting of three main parts and written by the
Moving Picture Experts Group (ISO/IEC 13818). It describes the coding
