Bitmapped Font, Bitmap Font: A character FONT in which each individual letter form is stored as a table of PIXELS (a picture), in contrast to an OUTLINE FONT where each character is stored as a set of lines or strokes (a description of how to draw the character). Bitmapped fonts are fast and easy to RENDER onto a screen or printer - by simply copying the bits for the character - and for this reason were preferred on older computer systems (up to and including MS-DOS PCs) that used CHARACTER-BASED displays.

Bump Mapping: An extension of the technique Of TEXTURE MAPPING to create more realistic 3D images, in which an additional BITMAP (the bump map) applied to a surface contains not colour data but small displacements to be applied to the surface normal at each point. After the image is rendered, these displacements alter the angles of reflected rays in such a way as to convey the illusion of surface relief, even though the surface actually remains completely smooth.

Analogue video: A video signal that is captured transmitted and stored as a continuously varying voltage, rather than as a stream of bits as in digital video. Up until the advent of digital TV in the late 1990S, television worked by transmitted analogue video signals, and older video tape recorders such as VHS, PAL, Betamax and Umatic all store analogue signals.
