Abstract:
A system for processing sequences of digital still images to provide digital video effects including:a first bidirectional processing datapath coupled to at least one configurable switch for transferring a first sequence of digital still images between the first bidirectional processing datapath and the at least one configurable switch;a second bidirectional processing datapath coupled to the at least one configurable switch for transferring a second sequence of digital still images between the second bidirectional processing datapath and the at least one configurable switch;wherein the at least one configurable switch selectively couples the first and second bidirectional processing datapaths to a plurality of destinations and a plurality of sources, wherein each of the plurality of modes of configuration of the at least one configurable switch controls a direction of flow of the sequences of digital still images between at least one of the first and second bidirectional and at least one of the plurality of destinations and plurality of sources;wherein one of the plurality of destinations includes outputs connected to inputs of a mixer, and wherein one of the plurality of sources is an input connected to an output of the mixer; andwherein one of the plurality of destinations includes at least one output connected to an input of a keyer, and wherein one of the plurality of sources is an input connected to an output of the keyer.
