7 Glossary
DHCP: DHCP (Dynamic Host Conguration Protocol) is one of the TCP/IP protocol cluster. It is
mainly used to assign temporary IP addresses to computers on a network.
DDNS: DDNS (Dynamic Domain Name Server) is a service that maps Internet domain names to
IP addresses. This service is useful to anyone who wants to operate a server (web server, mail
server, ftp server and more.) connected to the internet with a dynamic IP or to someone who
wants to connect to an oce computer or server from a remote location with software.
eSATA: eSATA (External Serial AT) is an page that provides fast data transfer for external storage
devices. It is the extension specications of a SATA page.
GPS: GPS (Global Positioning System) is a satellite system, protected by the US, safely orbiting
thousands of kilometers above the earth.
PPPoE: PPPoE (Point to Point Protocol over Ethernet) is a specication for connecting multiple
computer users on an Ethernet local area network to a remote site. Now the popular mode is
ADSL and it adopts PPPoE protocol.
Wi-Fi: Wi-Fi is the name of a popular wireless networking technology that uses radio waves to
provide wireless high-speed Internet and network connections. The standard is for wireless local
area networks (WLANs). It is like a common language that all the devices use to communicate to
each other. It is actually IEEE802.11, a family of standard The IEEE (Institute of Electrical and
Electronics Engineers Inc.)
3G: 3G is the wireless network standard. It is called 3G because it is the third generation of
cellular telecom standards. 3G is a faster network for phone and data transmission and speed Is
over several hundred kbps. Now there are four standards: CDMA2000, WCDMA, TD-SCDMA and
WiMAX.
Dual-stream: The dual-stream technology adopts high-rate bit stream for local HD storage such
as QCIF/CIF/2CIF/DCIF/4CIF encode and one low-rate bit stream for network transmission such
as QCIF/CIF encode. It can balance the local storage and remote network transmission. The dual-
stream can meet the dierence band width requirements of the local transmission and the
remote transmission. In this way, the local transmission using high-bit stream can achieve HD
storage and the network transmission adopting low bit stream suitable for the uency
requirements of the 3G network such as WCDMA, EVDO, TD-SCDMA.
On-o value: It is the non-consecutive signal sampling and output. It includes remote sampling
and remote output. It has two statuses: 1/0.
