ABSTRACT:
Two channels of output of sequences of digital still images are input to a DVE system which has pipelined memory circuits rather than frame buffers. The DVE system includes a DVE unit which performs arbitrary three-dimensional, digital video effects on the two channels of input to provide a composite output sequence. 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, which may indicate that an output pipeline is full. The DVE system also provides a control signal to prevent input when it cannot receive input or it is not providing output.
