1. 概述：

This IP is a highly versatile video multiplexer that allows one video stream to be inserted over another.  By cascading a series of video overlay modules together, any number of video sources may be multiplexed together. The module supports input video streams of any resolution or aspect ratio up to 2¹⁶   x 2¹⁶  pixels in size. Video overlay parameters may be changed on a frame-by-frame basis to dynamically change the size and position of the video overlay.

Pixels and syncs flow in and out of the video overlay module in accordance with the valid-ready pipeline protocol. The pipeline protocol allows both input and output interfaces to be stalled independently.

In addition, the overlay module supports a number of blending operations including an 8-bit alpha channel and bitwise AND, OR and XOR functions.
