pixels and a refresh rate of 30 frames per second. Note that MPEG-1 allows resolutions up to 4095 x 4095 active pixels; however, there is a "constrained subset" of parameters defined as SIF. The computer industry, which uses square pixels, has defined SIF to be 320 x 240 active pixels, with a refresh rate of whatever the computer is capable of supporting.

SMPTE time code – A standard for a signal being recorded to uniquely identify each frame of the video signal. It is used to control editing operations. (SMPTE stands for Society of Motion Picture and Television Engineering).

Stream – The flow of data as a sequence of bits. It is also referred to as bit stream.

Sub-carrier – A high-frequency carrier in a composite color TV system, on which the chrominance information modulates before combining with the luminance signal.

Subnet Mask – An extension of the IP addressing scheme that allows a site to use a single IP network address for multiple physical networks.

S-Video – A video signal that carries separate luminance and chrominance signals.

Switch – In telecommunications, a switch is a network device that selects a path or circuit for sending a unit of data to its next destination. A switch may also include the function of the router, a device or program that can determine the route and specifically what adjacent network point the data should be sent to. In general, a switch is a simpler and faster mechanism than a router, which requires knowledge about the network and how to determine the route

TCP – Refers to the Transport Control Protocol, used along with the Internet Protocol (IP) to send data divided into data packets over the Internet. While IP handles the actual delivery of the data, TCP keeps track of the individual data packets for efficiently routing data through the Internet.

Telnet – The TCP/IP standard protocol for remote terminal service. TELNET allows a user at one site to interact with a
