Rack Unit. It is a unit of measure used to describe the height of equipment
intended for mounting in a 19-inch rack or a 23-inch rack. One rack unit is
1.75 inches (44.45 mm) high.
Standard Definition.
Serial Digital Interface.
270 Mbps Standard-Definition Serial Digital Interface.
Simple Definition Television.
Society of Motion Picture and Television Engineers.
A Standards Organization devoted to advancing theory and application in
motion imaging, including film, television, video, computer imaging, and
telecommunications.
Simple Network Management Protocol.
SNMP provides a means to monitor and control network devices, and to
manage configurations, statistics collection, performance, and security.
SNMP network management is based on the client and server model. Each
managed host runs a process called an agent. The agent is a server
process that maintains the Management Information Base (MIB) database
for the host. SNMP uses ports 161 and 162.
Single Program Transport Stream
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.
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.
Transport Stream.
A multiplex of several Elementary Stream that are contained in packets.
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 is communication between a single sender and a single receiver
over a network.
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).
