ADSL—Asymetric Digital Subscriber Line. - Faster than ISDN and unmetered.
	BANDWIDTH—The maximum amount of information passed over a connection in one second. It is measured either in Kbps (kilobits per second) or Mbps (megabits per second)
	BIT RATE—The speed at which binary content is streamed on a network, measured in kilobits per second (kbps).
	BROADBAND—The ability to transfer data packets at rates higher than traditional dial-up connections (i.e., ISDN, 56K modem). Broadband streams enable the transmission of a larger and higher-quality image and richer and better-quality sound. Broadband streams are available with DSL, cable modem, wireless and T-1 or higher Internet connections.
	BUFFERING—A delay at the beginning of a streaming media presentation to make sure enough data is available to get the best playback quality at a given bit rate.
	CAPTURE—(or, Digitize/ise) The process of transforming analogue and digital audio and video from tapes, cassetttes etc. to binary files for editing and encoding purposes on a non-linear platform.
	CLIENT—A software application that receives data from a server. A web browser such as Internet Explorer or Netscape Navigator is a client of a server.
	CLIP—A single audio or video file within a presentation
	CODEC —Compressinon/Decompression. The compression algorithms used for creating media files during the encoding process. CODECs convert data between uncompressed and compressed formats. This compression reduces the bandwidth a clip consumes allowing for real-time transmission across the Internet.
	COMPRESSION ALGORITHM—Algorithms are mathematical formulae used for increasing efficiency. In the case of compression, the algorithm sets the rules that are followed to make a file smaller and, therefore, easier to deliver over the Internet.
	DE-INTERLACE—A process used to convert interlaced frames to progressive scan frames. This process is necessary to properly prepare native television signals for playback on progressive scan devices, such as computer screens.
	DSP— Digital Signal Processing. Use of mathematical expressions, such as algorithms, to modify digital signals.
	ENCODING—The processing of digitised audio and video so that it can be streamed over the Internet. The process involves rewriting or transfering media sources from one format to another. For example a .wav can be encoded into a .ra (RealAudio) file.
	HOSTING—The storage of media files on servers specifically designed for streaming over the Internet. Server protocols, such as RTSP, are designed to host and stream video and audio on the Internet
	ISDN—Integrated Services Digital Network 64K/128k. Speeds vary and can be limited by inconsistencies in the services provided by Internet Service Providers.
	LIVE EVENT WEBCASTING—The process of broadcasting an encoded live signal over the Internet to a global audience of simultaneous viewers as the event occurs. Capturing, encoding, and hosting an event, such as a concert, award show, meeting, or conference, usually from a remote location, for Internet broadcast on a one-time or limited basis. Live events usually require establishing dedicated telecommunication lines and/or satellite uplinks for streaming over the Internet. The end user does not receive a storable experience and must access archived material to view again.
	LIVE SIGNAL ACQUISITION—Acquisition of a broadcast signal from a satellite, Vyvx, microwave, or fiber -optic. Live signal acquisition allows traditional media producers a cost-effective way to simulcast original broadcast content over the Internet.
	PHOTONICS—The science of photons, or light. Optical networks will be the hallmark of the broadband era.
	RICH MEDIA—Interactive multimedia that attracts and holds the attention of internet users.
	SKINS—These customise the appearance of media players e.g. RealJukebox.
	SMIL—Synchronized Multimedia Integration Language - based on XML It specifies how and when each streaming data type will play.
	STREAM—The continuous delivery of small packets of information
	STREAMING MEDIA —Streaming allows the user to play media from the Internet immediately, without downloading the entire media file, thus eliminating the wait of downloading. The advantage for the copyholder is that the end user does not receive a storable copy of the file.
	TELECINE—A process that transfers film at 24 fps to a rate that is compatible with television playback standards. The process typically involves a conversion of the frame rate to 29.97 fps (for NTSC) and 25 fps (for PAL/SECAM) by using a sequence of whole frames and interfield frames.
	THROTTLING—Similar to being restricted to driving at 55 mph. - Telcos and cable companies do this with high-speed Internet services, restricting the maximum speed of your ISDN, DSL or cable-modem connection to conserve their network bandwidth. ISPs are also guilty of throttling your connection, therefore reducing your bandwidth and spoiling your fun.
	URL—Universal Resource Locator
	VBR ENCODING—As opposed to CBR (Constant Bit Rate), VBR (Variable Bit Rate) allocates additional bandwidth to sections of encoded media that require more complex motion and higher-quality sound. Overall, VBR produces a higher-quality encode when compared to CBR encodes with similar bit rates.
	WALLED GARDEN —The practice by which an Internet service giant gives customers easier access to its own and its partners' content than to that of its competitors.
	WAP—Wireless Application Protocol. With WAP, Internet companies need to configure their content only once and it can then show up on the tiny screens of almost every wireless device, regardless of service provider.
	XHTML—eXtensible HyperText Markup Language. The new standard from W3 Consortium which combines XML and HTML to make provision for dynamic markup.
