Appendix D • Glossary of Terms

Color Noise – Random interference in the color portion of a composite video system. Because of reduced color bandwidth or color subsampling, color noise appears as relatively long streaks of incorrect color in the image.

Collision – A collision is an Ethernet event occurring when two Ethernet frames collide. This may happen since every host can transmit the moment it has something to transmit. Therefore two hosts may transmit at the same time causing a collision.

Collision Plane – A collision plane is a bus or a wire where collisions can take place in networks.

Composite Video – A color video signal that contains all of the color information in one signal. Typical composite television standard signals are NTSC, PAL, and SECAM.

Compression – A digital process that allows data to be stored or transmitted using less than the normal number of bits. Video compression techniques reduce the number of bits required to store or transmit images.

Contrast – The contrast of a picture describes the difference between light and dark. In a picture with high contrast the transition from dark to light is very clear.

D1 – A format for recording digital video based on the ITU-R 601 standard. The term is also used to describe the resolution of

adigital video stream in comparison to the CCIR-601 resolution, for example D1 or Half D1.

Datalink Layer – Layer II in OSI Systems, This layer assures the flow of information in the network.

Data Rate – The speed of a data transfer process, normally\ expressed in bits per second or bytes per second (e.g. the data rate of CD-ROM is 1.2 Mbps).

Data Transfer Rate – The transfer rate of the storage media itself. For example, the maximum data transfer rate of a CD- ROM is 1.2 MB.

Default Gateway – The Default Gateway is a routing device that receives all packets being sent to destination addresses
