TCP
Transmission Control Protocol.
One of the main protocols in TCP/IP networks. TCP enables two hosts to
establish a connection and exchange streams of data. TCP guarantees
delivery of data and packets, and will be delivered in the same order in
which they were sent. While IP takes care of handling the actual delivery
of the data, TCP takes care of keeping track of the individual units of data
(called packets) that a message is divided into for efficient routing through
the Internet.
TCP / IP
Transmission Control Protocol/Internet Protocol
Two interrelated protocols that are part of the Internet protocol suite. TCP
operates on the OSI transport layer and breaks data into packets. IP
operates on the OSI network layer and routes the packets. While IP takes
care of handling the actual delivery of the data, TCP takes care of keeping
track of the individual units of data (called packets) that a message is
divided into for efficient routing through the Internet. TCP/IP allows the
construction of very large networks with little central management.
TDT
Time and Date Table.
A mandatory Digital Video Broadcast (DVB) SI table that supplies the
Coordinated Universal Time (UTC) time and date.
TID
Table Identifier
TID Ext
Table Identifier Extension
TOT
Time Offset Table.
An optional (DVB) SI table that supplies the actual UTC-time including also
time offset information coded as MJD.
TS
Transport Stream.
A multiplex of several Elementary Stream that are contained in packets.
TVCT
Terrestrial Virtual Channel Table (ATSC)
UDP
User Data Protocol.
A connectionless protocol, like TCP, that runs on top of IP networks. Unlike
TCP/IP, UDP/IP provides very few error recovery services, offering instead
a direct way to send and receive datagrams over an IP network without
acknowledgements for guaranteed delivery.
Unicast
Unicast is communication between a single sender and a single receiver
over a network.
UTC
Coordinated Universal Time.
UTC is the time standard by which the world regulates clocks and time. In
casual use, UTC corresponds to Greenwich Mean Time (or GMT).
VANC
Vertical Ancillary.
Ancillary packets located in the vertical blanking interval of a digital video
signal.
VBE
Variable Bits per Element. Refer to CBE entry.
VBI
Vertical Blanking Interval.
In analog video, the interval after the last displayed line of video in a field
and before the first displayed line of video in the next field, during which
a television receiver will synchronize vertically.
