Abstract

A network system provides video information on demand concerning real estate properties, and in principle includes a large number of real estate information server locations as viewing sites. The servers are interconnected by a dedicated hard wire network so that video information may be shared. The video information is recorded, stored, transferred, and displayed using high speed digital data handling techniques. The video information is accompanied by digitized audio sound tracks.
