ABSTRACT:
Disclosed is a system and method for mixing a plurality of graphics and video signals to create a desired output format, the desired output format being a mixture of the received signals. The mechanisim for achieving this rich format is a multi-modal graphics video overlay controller. The controller having a set of opcodes, selects a subset of the opcode set, this selection being a function of a desired output format of the mixed signals. The subset of opcodes is then utilized to control the means for selectively switching among the received graphics and video signals to create the desired output format. The selective switching is accomplished on a pixel by pixel basis.
