Abstract

Two channels (A, B) or output of sequences of digital still images are input to a DVE system which has pipelined memory circuits (80, 82, 84) rather than frame buffers. The DVE system includes a DVE unit (52) which performs arbitrary three-dimensional, digital video effects on the two channels of input to provide a composite output sequence (C). The DVE system thus operates on sequences of digital still images rather than video signals. The DVE system is also adapted to prevent output upon receipt of a control signal (S1), which may indicate that an output pipeline is full. The DVE system also provides a control signal (S2) to prevent input when it cannot receive input or it is not providing output.
