Abstract
Alpha values associated with video mixing operations are sent to a memory on a low pin count bus. The memory is accessible to a video mixer, which retrieves the alpha values to perform a mixing operation. The alpha values for a field are sent to the memory during the field time for a previous field rather than during the vertical blanking interval. The alpha values may be compressed prior to transmission.
