We propose a residential HDTV distribution system that is composed of UWB and IEEE 1394. This system converts multi-channel MPEG TS broadcasting data into IEEE 1394 packets or UWB packets based on IEEE802.15.3 WPAN. Any distributed UWB packets are again converted into MPEG TS data through a UWB-to-IEEE1394 bridge. Moreover, this system can also transmit IPTV packets encapsulated with IEEE 1394 packets from a home gateway or home server to a home UWB network. We implement UWB MAC and physical layer chips using CMOSASICs.
