<p><P>PROBLEM TO BE SOLVED: To provide a UWB communication system capable of transferring a video signal transmitted from a host PC to a projector or a monitor at high speed, and to provide a UWB transceiver to be used in the wireless UWB communication system. <P>SOLUTION: A dongle type UWB transceiver A is mounted on a USB connector 12 arranged in the host PC 1. The VGA plug 51 of a UWB transceiver B is mounted on the VGA connector 21 of the projector 2. The host PC1 converts a VGA signal into a USB signal and outputs it to the USB connector 12. The DC voltage of the UWB transceiver A is supplied from the host PC1 via the DC terminal of the USB connector. The UWB transceiver B includes: a UWB transmission/reception circuit 52; a USB/VGA signal converting circuit 53; and the VGA plug 51. The DC voltage of the UWB transmission/reception circuit 52 and the USB/VGA signal converting circuit 53 is supplied via the VGA connector 21 arranged in the projector 2. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
