Digital Video Overlay Module

General Description

Video overlay module permits multiple video streams to be multiplexed together to give a single video output. Supports any number of input video sources at any input resolution or aspect ratio. Features programmable video overlay position, 8-bit alpha transparency and logical blend operations such as AND, OR and XOR. Overlay positions may be changed on a frame-by-frame basis to give dynamic video movement.
