Abstract
A general purpose video special effects system and method is provided which utilizes at least one video rate RAM which has stored in it pre-computed data which is stored at addresses determined by all possible values of the video inputs to be utilized. Each special effect has a pre-computation which is accomplished by a threaded interpretive code technique operating on a parameter stack to facilitate the speed of computation. By the use of more than one video rate RAM, the effect may be changed on a line-by-line basis or even faster. Special effects are stored using a 'composition of functions' technique that allows the same special effect to be pre-computed for changing bit widths or positions of input and output channels. Special effects can be built by using or combining functions provided. New functions can be defined by the operator by composition of standard or previously created functions.
