Glossary
Domain
A domain contains a group of computers that can be accessed and administered with a common set of rules.
Domain can also refer to the IP address of a website on the Internet.
DNS
DNS (Domain Name System) is a system used by the Internet and private networks to translate domain names into
IP addresses.
mDNS
mDNS (Multicast DNS) refers to the use of IP multicast with DNS to translate domain names into IP addresses and
provide service discovery in a network that does not have access to a DNS server.
Ethernet
Ethernet, standardized as IEEE 802.3, refers to a series of technologies used to connect computers and other
devices to a LAN (Local Area Network) or wide area network (WAN).
Firmware
Firmware is a class of software held in non-volatile memory that provides the low-level control for a device’s
hardware.
Gigabit Ethernet (GigE)
An Ethernet capable of transmitting frames at a rate of a gigabit per second. A Gigabit capable Ethernet network
is recommended for NDI production workows.
IP
IP (Internet Protocol) is the communications protocol for the Internet, many wide area networks (WANs), and
most local area networks (LANs) that denes the rules, formats, and address scheme for exchanging datagrams or
packets between a source computer or device and a destination computer or device.
LAN
LAN (Local Area Network) is a network that connects computers and devices in a room, building, or group of
buildings. A system of LANs can also be connected to form a WAN (Wide Area Network).
Mbps
Mbps (Megabits per second) is a unit of measurement for data transfer speed, with one megabit equal to one
million bits. Network transmissions are commonly measured in Mbps.
NDI
NDI (Network Device Interface) is a standard allowing for transmission of video using standard LAN networking.
NDI® comes in two avours, NDI® and NDI|HX. NDI® is a variable bit rate, I-Frame codec that reaches rates of
around 140Mbps at 1080p60 and is visually lossless. NDI|HX is a compressed, long-GOP, H.264 variant that achieves
rates around 12Mbps at 1080p60.
Packet (Frame)
A packet s a unit of data transmitted over a packet-switched network, such as a LAN, WAN, or the Internet.
