Appendix D • Glossary of Terms

Driver – A software entity that provides a software interface to

aspecific piece of hardware. For example, the MPEG-5000 video driver provides software access to the video board hardware.

DSL – Refers to the Digital Subscriber Line, a technology for bringing high-bandwidth information to homes and small businesses over ordinary copper telephone lines. xDSL refers to different variations of DSL, such as ADSL, HDSL, and RADSL. Assuming your home or small business is close enough to a telephone company central office that offers DSL service, you may be able to receive data at rates up to 6.1 megabits (millions of bits) per second (of a theoretical 8.448 megabits per second), enabling continuous transmission of motion video, audio, and even 3-D effects. More typically, individual connections will provide from 1.544 Mbps to 512 Kbps downstream and about 128 Kbps upstream. A DSL line can carry both data and voice signals and the data part of the line is continuously connected. DSL installations began in 1998 and will continue at a greatly increased pace through the next decade in a number of communities in the U.S. and elsewhere. Compaq, Intel, and Microsoft working with telephone companies have developed a standard and easier-to-install form of ADSL called G.Lite that is accelerating deployment. DSL is expected to replace ISDN in many areas and to compete with the cable modem in bringing multimedia and 3-D to homes and small businesses.

EISA – Refers to a full 32-bit bus developed in 1989 to offer support for existing ISA expansion boards and to provide a platform for future growth. The EISA bus can accommodate more pins than an ISA bus. An EISA connector has a two-tier slot design accepting both ISA and EISA cards.

Encode – Refers to compressing.

Field – Refers to individual pictures inside a video stream. One- half of a frame is composed of odd (even) lines of video. These lines comprise the odd (even) field.

Fixed Bit-Rate- Refer to CBR (Constant Bit-Rate).
