Experimental digital video/audio storage server

This paper describes a network based digital video/audio storage server system (DVRS) and an experimental software environment created for computer vision and graphics researchers. The most significant feature of DVRS is its accessibility as a server for client machines. Two types of DVRS are realized: an actual DVRS and a pseudo DVRS. The actual DVRS is controlled by client machines for recording external analog video/audio and digital images/PCM audio data to a magnetic tape system and extracting digital images/PCM audio data sequences from a tape. The pseudo DVRS provides a small subset of the actual DVRS functions to support the debugging of application programs.
