Abstract
A method for capturing video frames from a plurality of video channels is provided. A list of a least two descriptors is formed for each of the plurality of video channels in a memory accessible to a direct memory access (DMA) engine, wherein each of the two or more descriptors for each channel is programmed to define a storage location for a sequential frame of video data for the channel. A sequence of video frames is received from the plurality of video channels, wherein for each channel, video frames are received at a frame rate for that channel. A DMA engine uses descriptors from the list to store video frames as they are received. The list is updated periodically to replace used descriptors.
