Abstract

A disc drive (80), camera (50) and a server (60) are connected to one another via a communication network (110) to make data communications between them. The disc drive (80) plays back a disc (90) to reproduce a recorded picture, combines the picture and a real-time world view supplied from the camera (50) based on an address table managed by the server (60) to produce a synthetic picture data, and outputs it to outside. For example, a recorded picture reproduced from the disc (90) and real-time world view taken by the camera (50) are combined to synthesize an picture. Thus, a content recorded in a recording medium can be used to produce a synthetic picture data.
