Abstract
In a video-on-demand service system, when a PDA terminal 8 is operated and a request is made for the distribution of the desired dynamic image content, that request is received by the nearest base station device 32 and is transmitted to a communication equipment 2 through a wireless LAN 200. The communication equipment 2 converts the request signal of the PDA terminal 8 to an appropriate format and transmits it to a data center 5 through an optical fiber 100. In the data center 5, the request signal is decoded, and the requested dynamic picture content is downloaded from a server and is then downloaded to the PDA terminal 8 of the user through the optical fiber 100, the communication equipment 2, the wireless LAN 200 and the base station device 32.
Claims31
