Description

本発明は、ホストＰＣから送出される映像信号をプロジェクタ装置またはモニタ装置へ高速転送できるワイヤレスＵＷＢ通信システムとその実施に用いる装置に関するものである。   The present invention relates to a wireless UWB communication system capable of transferring a video signal transmitted from a host PC to a projector apparatus or a monitor apparatus at a high speed, and an apparatus used for the wireless UWB communication system.

近年、ホストＰＣに取り込んだ動画やＤＶＤをプロジェクタ装置でスクリーンに映写して、プレゼンテーションを行ったり、居間をホームシアター化することが盛んになっていることは周知の通りであるが、その場合、図１に示すようにホストＰＣ１のＶＧＡポートとプロジェクタ装置２のＶＧＡポート間をＶＧＡケーブル３で接続する必要がある為、ホストＰＣ１とプロジェクタ装置２の設置場所が離れている場合には長尺のＶＧＡケーブルを用意しなければならず不便であった。   In recent years, it is well known that moving images and DVDs captured by a host PC are projected on a screen by a projector device to give a presentation and the living room is made into a home theater. 1, since it is necessary to connect the VGA port of the host PC 1 and the VGA port of the projector device 2 with the VGA cable 3, a long VGA is required when the installation location of the host PC 1 and the projector device 2 is far from each other. It was inconvenient because a cable had to be prepared.

そこで、２００６年８月の電波法施行規定の改定により認可された、周波数３．４〜４．８ＧＨｚのＵＷＢ（Ｕｒｔｒａ Ｗｉｄｅ Ｂａｎｄ）を利用した低送信電力、近距離高速通信を実現するワイヤレスＵＷＢ通信システムを構築しようとする場合、ＵＷＢ送受信機をホストＰＣとプロジェクタ装置またはモニタ装置へ装着することが考えられる。しかしその場合、ＵＷＢ送受信機を起動させるには電源が必要である。   Therefore, wireless UWB communication that realizes low transmission power and short-range high-speed communication using UWB (Ultra Wide Band) with a frequency of 3.4 to 4.8 GHz, which was approved by the revision of the enforcement regulations of the Radio Law in August 2006. When a system is to be constructed, it is conceivable that the UWB transceiver is mounted on the host PC and the projector device or monitor device. In that case, however, a power source is required to activate the UWB transceiver.

通常、図２に示すように、ホストＰＣ１側に取付けるＵＷＢ送受信機４は、ドングルタイプのＵＷＢ送受信機４として、ホストＰＣ１のＵＳＢコネクタに差込み、デバイス装置側（プロジェクタ装置２またはモニタ装置）のＵＷＢコネクタまたはケーブル付ＵＳＢコネクタにＵＷＢ送受信機５を取付け、ホストＰＣ１とデバイス装置間を無線でデータのやりとりを行うが、これらのＵＷＢ送受信機４、５は電源が必要であり、無線化したにも関わらずＡＣアダプター６などからの電源を必要とする。   Normally, as shown in FIG. 2, the UWB transceiver 4 attached to the host PC 1 side is plugged into the USB connector of the host PC 1 as a dongle type UWB transceiver 4 and the UWB on the device device side (projector device 2 or monitor device). A UWB transceiver 5 is attached to a connector or a USB connector with a cable, and data is exchanged between the host PC 1 and the device device wirelessly. These UWB transceivers 4 and 5 require a power source and are wireless. Regardless, power from AC adapter 6 is required.

ホストＰＣ１側はＵＳＢコネクタよりＤＣ電源の供給が受けられるが、デバイス装置側、即ちプロジェクタ装置２側はＤＣ電源を外部に出力するコネクタは備えていない為、電源供給を受けることができないので、プロジェクタ装置２側のＵＷＢ送受信機５にはＡＣアダプター（ＤＣ電源を供給）６が必要となる。
特開２００６−１６４０８１号公報 Although the host PC 1 side can be supplied with DC power from the USB connector, the device device side, that is, the projector device 2 side does not have a connector for outputting DC power to the outside, and therefore cannot receive power supply. An AC adapter (DC power supply) 6 is required for the UWB transceiver 5 on the apparatus 2 side.

The communication speed is about 480 Mbps at 3 m and about 110 Mbps at 10 m, and high-quality moving images such as high-definition video can be smoothly transmitted to the external device.

また、ＶＧＡケーブル配線が不要となり、しかも外部デバイス装置側のＵＷＢ送受信機にはＡＣアダプタが無いため最適のワイヤレスＵＷＢ通信システムを構築することが出来る。   In addition, since no VGA cable wiring is required and the UWB transceiver on the external device side does not have an AC adapter, an optimal wireless UWB communication system can be constructed.
