GlossaryIPTV (Internet Protocol Television): a system where a digital television service is delivered by using Internet Protocol over a network infrastructure. This may include delivery by a broadband connection. IPTV is television content that, instead of being delivered through traditional broadcast and cable formats, is received by the viewer through the technology used for computer networks. Set-Top
Box ‘STB’ (a.k.a. Receiver): In
IPTV networks, it’s a small computer providing
two-way communication on an IP network.
It decodes the video streaming media which
eliminates the need for any coaxial cabling. Ethernet
Cable: A type of network technology
for local area networks; coaxial cable carries
radio frequency signals between computers
at a rate of 10 megabits per second.
The most common form of Ethernet cable is
the telephone-like RJ-45 cable. Using
a "crossover cable," two machines can be
plugged together using their Ethernet ports.
The crossover cable is designed for direct
connection between two Ethernet devices
(PCs, peripherals, etc.) without a hub or
switch in between. High-Speed
Internet: The term commonly refers
to Internet access via cable and DSL, which
is as much as 400 times faster than analog
dial-up. The term has always referred to
a higher-speed connection but the speed
threshold varies with the time of day. Widely
employed in companies, the 1.5 Mbps T1 line
was often considered the starting point
for broadband speeds, in contrast the FCC
defines broadband as a minimum upload speed
of 200 Kbps. Modem:
A modem is a device or
program
that enables a computer to transmit data over,
for example, telephone or cable lines. Computer
information is stored digitally,
whereas information transmitted over telephone
lines is transmitted in the form of analog
waves. A modem converts information between
these two forms of waves. Router:
A device that forwards data packets along
networks. A router is connected to at least
two networks, commonly two LANs or WANs
or a LAN and its ISP’s network. Routers
are located at gateways, the places where
two or more networks connect. USB
Key: Also known as a flash drive
or keychain drive -- is a plug-and-play
portable storage device that uses flash
memory and is lightweight enough to attach
to a key chain. A USB drive can be used
in place of a floppy disk, Zip drive disk,
or CD. When the user plugs the device into
the USB port, the computer's operating system
recognizes the device as a removable drive
and assigns it a drive letter. Bandwidth:
The amount of data that can be transmitted
in a fixed amount of time. For digital devices,
the bandwidth is usually expressed in kilobits
per second (kbps) or bytes per second. For
analog devices, the bandwidth is expressed
in cycles per second, or Hertz (Hz). Video
on Demand (VOD): A technique which
allows users to select and watch video content
over a network as part of an interactive television system. VOD systems can "stream" content, which allows for viewing in real time.
This system can also "download" content. With this
approach the program is brought, in its
entirety, to a set-top box
before viewing starts. The latter is more
appropriately termed "store and forward".
The majority of cable and
telco
based VOD systems use the streaming approach,
whereby a user buys or selects a movie
or television
program and it begins to play on the
television set almost instantaneously. RCA Cable: A standard type of cable used to transmit analog audio and composite-videosignals between devices such as televisions, satellite or cable receivers, VCRs, game console systems, speakers, and more. Typical RCA cables will have two or three color coded connectors. RCA audio cables have two connectors: red (right stereo) and white or black for left stereo. An additional third connector on an RCA cable will be yellow for composite video. |
