Appendix D • Glossary of Terms

The letterbox method produces a black band at the top and bottom of the screen, wasting the television's vertical resolution.

AVI – Refers to Audio Video Interleaved, the original term for Microsoft’s Video For Windows.

Bandwidth – The amount of data being able to transmit during a defined period of time. For digital devices, the bandwidth is usually expressed in bits per second or bytes per second. For analog devices, the bandwidth is expressed in cycles per second or Hertz (Hz).

B Frames – Bi-directional frames; one of the three picture types in MPEG compression. B frames are coded in relation to previous or subsequent I or P frames. B frames do not serve as a reference for other frames.

Bit Stream – A serial sequence of bits.

Bitmap – An image made up of pixels on the screen, stored as a collection of bits. A bitmap file usually carries the extension BMP.

Bits per Pixel – The number of bits used to represent the color value of each pixel in a digitized image. The color value of pixels can be 8, 16 or 24 bits. When the color value of a pixel is 24 bits there are 16.6 million colors in an image.

Bridge – A network component connecting two LANs, thus extending the range of the network. Bridges check data and forward them across LANs.

Brightness – The brightness of a picture describes how much light appears to be emitted from it.

Broadcast – Transmitting data simultaneously to several or all stations within a network.

Brouter – A network component that serves as both a Bridge and a Router.

Buffer – Space being allocated on a system’s Random Access Memory (RAM) where data are temporarily stored until being transferred to another part of the system. In streaming
