Appendix D • Glossary of Terms

applications, buffers store video or audio data until there is enough information for the stream to be composed.

Bus Topology – A LAN network in which all nodes connect to the same cable. Data transmit across this one cable.

CBR – Refers to Constant Bit-Rate and stands for the bit-rate of a data stream remaining constant during compression throughout the entire encoding process. This parameter may also be referred to as Fixed Bit-Rate.

CCIR-601 – A standard (now known as ITU-R 601) that defines the encoding parameters of digital television for studios. ITU-R 601 refers to color difference (Y,R-Y, B-Y) and RGB video. It defines sampling systems, RGB/Y, R-Y and B-Y matrix values and filter characteristics. ITU-R 601 usually refers to color difference component digital video (as opposed to RGB) for which it defines 4:2:2 sampling at 13.5 MHz with

720luminance samples per active line and 8 or 10-bit digitizing.

Clip – A segment of a video or an entire video being considered one unit based on content.

Coaxial Cable – Cable consisting of a central copper wire being surrounded with insulation and a grounded shield of braided wire. Coaxial cables are widely used in the cable television and computer industries. It is less prone to interference than regular wire cables.

CODEC – Acronym for encoder and decoder.

Connectionless vs. Connection-oriented Protocols – When using a connectionless protocol, hosts are sending data without establishing a connection with the recipient. The host does not know whether the data arrive at their destination. Connection-oriented protocols require a designated path to be established between the sender and receiver.

Coding – The process of representing a varying function as a series of digital numbers.
