 Under construction IEEE 1394: The interface standard that enables the direct transfer of DV between devices such as a DV camcorder and a computer; also used to describe the cables and connectors utilizing this standard. i.LINK: The Sony trade name for IEEE 1394. Inter-frame compression: Also known as temporal compression, inter-frame compression reduces the amount of video information by storing only the differences between frames. Interlacing: System developed for early television and still in use in standard television displays. To compensate for limited persistence, the electron gun used to illuminate the phosphors coating the inside of the screen alternately draws even, then odd horizontal lines. By the time the even lines are dimming, the odd lines are illuminated. We perceive these “interlaced” fields of lines as complete pictures. Intra-frame compression: Also known as spatial compression, intra-frame compression reduces the amount of video information within each frame individually. IP: Internet Protocol, the basis of most Internet protocols, breaks up large chunks of information into digestible packets. In addition to the data being conveyed, each packet (also known as a datagram) carries a header containing the source and destination IP addresses, as well as a sequence number that allows the destination computer to reconstruct the packets in the correct sequence, when they arrive. IP address: A numeric identifier for a computer or device on the Internet. An IP address consists of four numbers separated by periods, or dots (e.g., 192.168.0.1), representing a unique 32-bit address. An IP address consists of a network portion and a host portion; how many bits designate the network and how many designate the host varies. Glossaire (PDF : 168 ko) |
