Glossary
Codec
An abbreviation for Coder-Decoder. An electronic
device that converts an analog signal such as voice or
video to a digital data stream, compresses it, and sends
it over a digital communications line. Another codec
reverses the process at the receiving site.
Compression
A task where a codec compresses data before sending
it over a digital communications line.
Interface
A protocol connecting two different devices so that
they can communicate with each other.
ISDN
An acronym for Integrated Services Digital Network.
This is a communications protocol defined by CCITT
on transmission of integrated voice, video, and data.
Bandwidths include basic (64 Kbps) and primary rate
(1.544 and 2.048 Mbps.)
Menu
A collection of settings shown on the TV monitor
which the user can change.
PinP
An abbreviation for Picture-in-Picture. This function
allows the user, while keeping the remote scene on the
TV monitor, to display the local scene in a smaller
window on the same TV monitor.
Subaddress
One ISDN line can support up to 8 devices. Because
all these devices share the same line number,
subaddresses are applied to them so that each has a
unique number.

zoom lens you can quickly move in or out on an
