A video communications system is provided that makes it possible for home viewers to download a movie in digital format from a large archive library, store the digital movie file locally, and view the movie at any convenient time. The system may limit access to particular movies and provides an accounting system that is used to bill downloads to the viewer's account as well as to post royalty payments to movie providers. Frequently viewed movies are quickly accessible via random access mass storage while infrequently viewed movies may be called up from a streaming tape archive. The digitalization of the program source allows for playback at various speeds, as well as pause, with no distortion or loss in picture quality.
