Abstract
The invention provides apparatus and methods for concurrently acquiring video data from multiple video data sources. The invention comprises an asynchronous interface that collects pixel data from multiple video data sources. A packet manager collects the pixel data and generates a packet data signal that represents the pixel data collected from the multiple video data sources. The packet manager transmits the packet data signal to a pixel buffer memory that includes an address generator that separates out the pixel data associated with each of the video data sources and that stores the pixel data in a video memory in a manner suitable for video display.
