Abstract
An apparatus for providing VCR-like “trick mode” functions, such as pause, fast-forward, and rewind, in a distributed, video-on-demand program environment. Trick modes are supported by locally altering the viewing speed for each user who requests such functions, without affecting the operation of the central data source in any way. Thus, a virtual unlimited number of viewers are able to enjoy random access to video programming, including virtually continuous trick mode functionality. This is accomplished in a manner that is operable with existing telephone and cable distribution infrastructure.
