リモート制御装置及びデータ転送システムRemote control device and data transfer system
　本発明は、リムーバブルな記録デバイスの情報とＡＶ機器とが通信するためのリモート制御装置と、それを備えたデータ転送システムとに関するものである。 The present invention relates to a remote control device for communication between information on a removable recording device and an AV device, and a data transfer system including the remote control device.
　近年、ＵＳＢ（universal serial bus）メモリデバイスやＳＤ（secure digital）メモリカードといった小型、軽量の記録デバイスが普及し、テレビやＤＶＤ（digital versatile disk）レコーダ等のＡＶ機器にも、これら記録デバイス内の情報を読み書きするための接続端子、及び接続機能が搭載されている。また、最近のＡＶ機器では、ネットワーク等を通じてＡＶ機器制御ソフトウェアのダウンロード等が一般化しており、新規格のＵＳＢデバイスやＳＤカードに対応することも可能である。 In recent years, small and lightweight recording devices such as USB (universal serial bus) memory devices and SD (secure digital) memory cards have become widespread, and AV devices such as televisions and DVD (digital versatile disk) recorders are also included in these recording devices. A connection terminal and a connection function for reading and writing information are mounted. In recent AV devices, downloading of AV device control software and the like has become common via a network or the like, and it is also possible to support new standard USB devices and SD cards.
　例えば、ＵＳＢメモリデバイスをＡＶ機器に接続する際、ＵＳＢメモリデバイスとＡＶ機器とを位置的に離した環境で利用する方法としては、ワイヤレスＵＳＢ装置等の、ＡＶ機器とＵＳＢメモリデバイスとをワイヤレスで接続するための装置を新たに設ける必要があった。また、ワイヤレス転送時には有線通信と比較して転送劣化が発生するため、転送効率向上のための取り組みが行われてきた（特許文献１参照）。 For example, when a USB memory device is connected to an AV device, a method for using the USB memory device and the AV device in an environment where the USB memory device and the AV device are separated from each other is a wireless USB device or the like. It was necessary to newly provide a device for connection. In addition, since transfer degradation occurs during wireless transfer compared to wired communication, efforts have been made to improve transfer efficiency (see Patent Document 1).
