Abstract
The technical field of the invention generally concerns systems for interactive access to stored video data. In particular, a video file server 20 includes both a random access data storage subsystem 78 and a archive data storage subsystem 82 for storing compressed video data. In response to commands from subscriber system 66, the video file server 20 transmits compressed video data to the subscriber systems 66 over lines 64A-64H, or receives compressed video data therefrom. Commands from the subscriber systems 66 may cause the video file server 20 to store compressed video data received from the subscriber systems 66 in the random access data storage subsystem 78 and/or archive data storage subsystem 82. Compression-decompression cards 42 included in the video file server 20 provide an authoring capability for storing compressed video and/or audio data in the random access data storage subsystem 78 and/or archive data storage subsystem 82, and for converting from one data compression standard to another.
