GLOSSARY

Bandwidth:

Digital bandwidth, network bandwidth or just band- width is a measure of available or consumed data com- munication resources expressed in bit/s (bits per sec- ond) or multiples of it (kbit/s, Mbit/s, etc.)

Buffer:

Memory used to temporarily hold data. In streaming, the buffer allows content to continue playing uninter- rupted during minor fluctuations in band width. If the buffer runs our before the connection stabilizes, the stream will have to rebuffer, or pause to allow the buffer to refill.

Codec:

A codec is a device or program capable of performing encoding and decoding on a digital data stream or signal.

DHCP:

Dynamic Host Control Protocol, DHCP, is a protocol where a DHCP server on a network hands out IP address automatically to devices that request one.

Dolby Digital:

Dolby Digital, or AC-3, is the common version contain- ing up to six discrete channels of sound, with five chan- nels for normal-range speakers.

Dolby Digital Plus:

Dolby Digital Plus (DD+ or E-AC-3 (Enhanced AC-3)), is a digital audio compression scheme. E-AC-3 has a num- ber of improvements aimed at increasing quality at a given bitrate compared with legacy Dolby Digital (AC-3).

Ethernet:

A way of connecting equipment together in a local area network or LAN. Ethernet cables look like thick tele- phone cables and connect computers and other internet ready devices together or to devices like modems, routers, switches, etc. Physically the Ethernet cable con- sists of twisted pair copper cables (usually Cat-5 or Cat- 6 in home networks) terminated with RJ-45 connectors.

H.264:

H.264 is a state-of-the-art digital encoding format for high definition video and provides powerful compression technology that delivers a superior video experience at a low bit rate.

HDMI:

High-Definition Multimedia Interface. A connection type that transmits uncompressed digital video and audio signals between devices, such as: a Blu-ray Disc player and HDTV. HDMI connections process a special author- ization signal between the equipment and use HDCP to encrypt the transmission.

Hub:

Similar to a switch except that traffic from one connec- tion point is broadcast to all others.

Internet:

The internet is a global system of interconnected com- puter networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It carries a vast array of information resources and servic- es, most notably the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail.

IP Address:

Internet Protocol Address. An IP address is numerical sets of numbers consisting of four (4) blocks of up to three (3) digits each in the range of 0 to 254. Every device on a network must have its own unique IP address. For LANs there are special sets of IPs that are used. These consist of the following blocks:

10.x.x.x – where x = a number from 0 to 254.

ISP:

An Internet Service Provider (ISP), usually for a month- ly subscription fee, will allow a user to connect to the Internet. Some ISPs directly put their users on the Internet, while others will send a connection through its or a different company’s servers.

LAN:

Local Area Network– A high speed data network installed in a small area such as a home or office. Multiple devices can be connected to share information and the Internet. LANs can be wired (by Ethernet cable) or wireless (Wi-Fi)

Media Streaming:

The process of receiving and playing back audio, video, and photos in real time from a remote source over the Internet without having to actually download and save files to the computer’s hard drive. Examples of media streaming include: Videos on demand, Internet radio stations, Music services, and Photostreams.
