Abstract
Processing requirement at each computing element in a video server for a video on demand (VOD) system are reduced to only those needed for VOD, resulting in a less expensive processor with less memory and, hence, lower cost. A hybrid video server architecture combines the best features of massive parallel processor (MPP) and workstation designs into a cost effective high performance system. Since it is not necessary to run a parallel relational database program in order to accomplish VOD data distribution, a unique type of switch element that is well matched to the VOD server problem is employed. By matching this switch element technology to an appropriate data storage technique, a full featured, responsive VOD server is realized that can be affordably installed at regional cable distribution centers nationwide.
