Digital Compression
A way of reducing the number of bits (ones and zeros) in a digital signal by using mathematical algorithms to eliminate redundant information thereby reducing the space it occupies when being transmitted or recorded.
Digital Transmission
In a digital telecommunication service, the original source is transformed into and transmitted as a series of digits in binary code (i.e. 0s or 1s). Voice, text, image or data are all equally capable of being coded as a digital signal, so that a single network can handle all four forms of transmission (multimedia). The string of binary digits can be abbreviated and then re-expanded on arrival, thus economising transmission capacity. Different strings of binary digits can be interleaved and transmitted together, thus permitting several separate conversations on a single line (multiplexing). The string of digits can be encrypted prior to transmission, to ensure a high level of information security and privacy. Through digitalization, even a severely degraded transmission can be reconstructed to reproduce perfectly the original source.

JET
Joint European Torus. The JET Joint Undertaking was established in June 1978 to construct and operate the Joint European Torus, of its time the largest single project within the European nuclear fusion programme. It was coordinated by Euratom (the European Atomic Energy Community), and the JET project went on to become the flagship of the Community Fusion Programme and the first fusion facility in the world to achieve significant production of controlled fusion power in 1991. In 1997 JET achieved more than 16 MW fusion power in Deuterium-Tritium plasmas. JET has furthered fusion science well beyond the goals of the original Design Team and is now evolving into a physics and technology basis for preparing ITER, the International Thermonuclear Experimental Reactor. Under EFDA, the European Fusion Development Agreement, a new JET Implementing Agreement has been set up to use the JET Facilities until at least the end of 2002, replacing the Joint Undertaking which came to an end on December 31st 1999.

Value Added Service (VAS), Value Added Network Service (VANS)
Services other than those under monopoly may be offered by other service suppliers which use national network as the basic transmission medium but "add value" to the basic transmission facility. What is exactly included in the notion depends on the regulatory situation of each country.
Video-on demand
Systems that enable the viewers to order and see a given programme at the exact time the viewer specifies. Near-video-on-demand (NVOD) systems approximate this capacity. This can be accomplished by staggering the start of a
programme every 15 or 30 minutes.
Virtual Reality
Computer-based systems that supply the visual and aural effects to project the viewer into an imaginary environment beyond the screen. The user is supplied with computer-generated images and sounds giving the impression of reality. The user interacts with the artificial world by means of sensors and apparatus including helmets ("visiocasque") and gloves which link the user's perceptions and movements and the audio-visual effects. Future work in virtual reality is directed towards increasing the impression of reality, for example by means of 3D images, and transmitting "virtual reality worlds" to users located remotely from the source computer.
