Glossary
Bridge device Bridge devices are devices that convert signals. For example, a Media Adapter is
a bridge device. It converts PC residing digital video, pictures or audio files to analogue signals.
The Media Adapter receives input from the PC and transforms it into a number of analogue
video and audio outputs that feed into classical non-networked TVs or audio systems.
DHCP When a device communicates with another device, it must have a unique address to
identify itself. Such an address is called an IP address. DHCP or Dynamic Host Configuration
Protocol is an Internet Protocol that manages and automates the assignment of IP addresses on
the network (along with distributing information about the network’s broadcast address,
netmask, gateway address and DNS addresses). A device that uses DHCP, requests an open
address from a DHCP server each time it makes a connection to that server. An alternative is to
use a fixed IP address (see IP address).
DMA Digital Media Adapter A Digital Media Adapter is a wireless digital device that allows
movies, pictures or music files to be streamed from a PC to non-networked audio-devices like
classical TVs and audio systems.
DNS DNS stands for Domain Name Server. A domain name is a meaningful and easy-to-
remember name for an Internet address e.g. www.homecontrol.philips.com. A Domain Name
Server translates domain names to IP addresses. (see IP address)
EPG EPG stands for Electronic Program Guide. EPG is the electronic equivalent of a printed
television program guide.
Gateway A gateway is a network point that acts as an entrance to another network. More
specifically, a gateway connects two networks that use different protocols. This way, gateways
make it possible for members of one network to make use of another network.
Hard Key Hard keys refer to the buttons on the right hand side of the RC9800i’s touch screen.
IR IR or Infrared is used to control audio-video devices. For instance, when you press a button on a
TV’s remote control, the remote control sends an Infrared (IR) signal to the TV. The TV receives
this signal and executes the command.
IP address When a device communicates with another device, it must have a unique address to
identify itself. Such an address is called an IP address, e.g. 192.168.100.1. When you add a
device to a network, you can either assign a fixed IP address to it or you can use DHCP (see
DHCP).
Netmask A netmask masks the network part of an IP address so that only the host computer part
of the address remains. A frequently used netmask is 255.255.255.0.
NTP NTP stands for Network Time Protocol. This protocol is used to synchronize date and time
information in a network of computers.
PVR PVR stands for Personal Video Recorder. This device is also known as a DVR, or Digital Video
Recorder.
SSID A Service Set Identifier is a sequence of characters that uniquely identifies a wireless local
area network. This name allows devices to connect to the desired network when multiple
independent networks operate in the same physical area.
UPnP Universal Plug and Play (UPnP) is a standard that uses Internet and Web protocols to enable
devices such as PCs, peripherals, intelligent appliances, and wireless devices to be plugged into
a network and automatically know about each other. With UPnP, when you plug a device into the
network, the device will configure itself, acquire a IP address, and use a discovery protocol
based on the Internet’s Hypertext Transfer Protocol (HTTP) to announce its presence on the
network to other devices.
USB USB stands for Universal Serial Bus. It is a plug-and-play interface between a computer and
add-on devices (such as audio players, joysticks and printers).
With USB, a new device can be added to your PC without having to add an adapter card or turn
your computer off.
