HDMI
The High-Definition Multimedia Interface (HDMI) is a digital data transmis sion standard for consumer
electronics/home appliances. HDMI connects digital audio/video sources to a compatible digital audio and/or
video device, such as a flat panel TV. HDMI also allows digitally transmitted audio and control signals on a single
cable for multi-channel digital audio sources.
PCM
The Pulse Code Modulation (PCM) is a method for converting analog audio signals to digital. PCM is used in
music CDs.
Dolby Digital
Dolby Digital is an encoding technology for audio signal compressions. Dolby Digital supports high-quality, high-
compression, multi-channel audio formats. The 5.1-channel surround format is utilized in digital broadcasts.
High-Definition Broadcast
HD is a digital television broadcasting system with greater resolution than traditional television systems. As
compared with the existing terrestrial analog broadcasting system capable of producing an image composed of
525 lines of resolution, the digital high-definition broadcasting system features 750 or 1125 lines, thus providing
higher definition and quality image.
Interlaced Scanning
In NTSC television or video image display, interlaced scanning first redraws every second line of the image field
(262.5 lines) per each image refresh in 1/60 of a second, then the remaining lines with a second refresh in 1/60
of a second for a complete frame of an image (525 lines). Effective scanning lines are expressed as “480i” and
“1080i” (“i” stands for “interlaced”).
Progressive Scanning
The progressive scanning redraws an image frame (all of its lines) in order per each image refresh. Compared to
interlaced scanning, progressive scanning produces less flicker, making it suitable for displaying text and still
images. Effective scanning lines are expressed as “480p” and “720p” (“p” stands for “progressive”).

Default Gateway
Default gateway is a node on a computer network that serves as an access point to another network. A default
gateway (such as a computer and router) is used to forward all traffic that is not addressed to a station within the
local subnet.
DHCP (Dynamic Host Configuration Protocol) Server
Provides a mechanism to allocate IP addresses to client hosts. In most cases, a broadband router serves as a
DHCP server in a home network.
DLNA (Digital Living Network Alliance)
The DLNA authorized logo makes it easy for consumers to recognize products that meet the new standard for
home network PCs and other digital devices, as set down in the DLNA Guidelines for interoperability. This allows
music, video, etc. to be enjoyed from various devices over a home network. This unit is compatible with music,
photo and video content, and is based on the DLNA Home Networked Device Interoperability Guidelines -
expanded: October 2006 (v1.5). This unit can be used to playback music, photos and video stored on a DLNA-
compatible server connected through a LAN cable.
Digital Living Network Alliance (DLNA) is dedicated to the simplified sharing of digital content, such as digital
music, photos and video among networked consumer electronics (CE) and PCs. By establishing a platform of
interoperability based on open industry standards, DLNA delivers technical design guidelines that companies
can use to develop digital home products that share content through wired or wireless networks in the home.
DNS (Domain Name Service) Server
DNS Server is a server that determines the name of network-computer within the Internet. The server functions
to exchange IP address to the hostname, hostname to the IP address.
Ethernet
A frame-based computer networking technology for local area networks (LANs). The flat panel TV supports
100BASE-TX.
