Abstract
The rate staggering technique for efficient storage and retrieval of video data is embodied in a data processing system including a disk array based video server, which includes a disk array for storing video data, a processor for processing data, a memory buffer for storing video data and a rate staggering controller. Data is transferred to a network from video server through a network interface and from the network to client stations employing devices having differing resolution capabilities. The processor executes tasks under control of the rate staggering controller. These tasks include a retrieval task which retrieves scalable video from the array of disks, a storage task which stores videos temporarily in the memory buffer, and a transmission task which transmits video to client stations through the network.
