摘要

A communication system for providing an HDTV (High Definition Television)-level multimedia service over a VDSL (Very-high-data-rate Digital Subscriber Line). The communication system comprises a client terminal device in a subscriber residence, a service provider, and an access network. The terminal device allows a user of the client terminal device to access a network through the VDSL. The service provider provides HDTV-level multimedia service programs and includes a zapping server. The zapping server accepts an HDTV-level multimedia service request signal of a channel requested by the user of the client terminal device, responds to the client terminal device, and provides one of the HDTV-level multimedia service programs corresponding to the channel requested by the user of the client terminal device. The access network is connected between the service provider and the client terminal device, and provides a optical communication path there between so that the client terminal device can receive the one of the HDTV-level multimedia service programs through the subscriber line.
