Abstract

A recording and reproducing system according to the invention is made up of a server apparatus and its terminals connected over a local area network that is administered independently in a limited area. In the system, any one of the terminals may generate a reproduction request and send it to the server apparatus over the LAN. In response to the request, the server apparatus reproduces video data from a storage medium installed therein and sends the reproduced video data to the requesting terminal over the LAN. In this manner, a user may reproduce video data and enjoy images thereof by remotely operating the server apparatus with ease from any terminal configured in the system.
