24.1. About the Mixer IP

The mixer Intel FPGA IP allows you to overlay video fields from multiple inputs on each other, either with or without alpha blending (transparency).

The mixer supports up to eight inputs (or layers). Layer 0 is the base layer, onto which the IP overlays every other layer (overlay layers). The resolution of the base layer determines the output resolution. Overlay layers can be offset horizontally and vertically within the base layer so that their first pixel overlays at any position within the base layer. Offsets must be such that the full overlay layer image remains inside the confines of the base layer.

The mixer supports both full and lite variants of the Intel FPGA streaming video protocol.
