- 2つの変圧器のみを利用して動作不能のネットワークデバイスをバイパスする方法であって、
第1の変圧器の第1の側から第1のビデオ信号を受信し、前記第1の変圧器の第2の側で前記第1のビデオ信号を表す第2のビデオ信号を生成するステップと、
制御信号に応答してスイッチアセンブリを動作させるステップと、
前記スイッチアセンブリが第1の動作状態である場合に、前記第2のビデオ信号をネットワークデバイスのターミナル入力部に与え、前記ネットワークデバイスのターミナル出力部を第2の変圧器の第2の側に結合するステップであって、前記ネットワークデバイスは前記ターミナル入力部から前記ネットワークデバイスの前記ターミナル出力部に前記第2のビデオ信号を流す、ステップと、
前記スイッチアセンブリが第2の動作状態である場合に、前記第1の変圧器の前記第2の側からの前記第2のビデオ信号を、前記ネットワークデバイスをバイパスしながら前記第2の変圧器の前記第2の側に直接的に与えるステップと、
前記第2の変圧器の第1の側で前記第2のビデオ信号を表す第3のビデオ信号を生成するステップと
を有する方法。 - 変圧器を2つしか有しないネットワークインターフェース装置であって、
第1及び第2の変圧器と、
第1のビデオ信号を受信するために前記第1の変圧器の第1の側に結合された第1の入力手段であって、前記第1の変圧器は該第1の変圧器の第2の側で前記第1のビデオ信号を表す第2のビデオ信号を生成する、第1の入力手段と、
前記第2の変圧器の第1の側に結合された第1の出力手段と、
ネットワークデバイスを介して第2の出力手段に結合された第2の入力手段と、
前記第1の変圧器の前記第2の側及び前記第2の変圧器の第2の側に結合されたスイッチング手段と
を有し、前記スイッチング手段が第1の状態である場合に、前記第1の変圧器の前記第2の側は前記第2の入力手段に結合され、前記ネットワークデバイスは前記第2の入力手段から前記第2の出力手段に前記第2のビデオ信号を流し、前記第2の変圧器の前記第2の側は前記第2の出力手段に結合され、前記スイッチング手段が第2の状態である場合に、前記ネットワークデバイスをバイパスしながら、前記第1の変圧器の前記第2の側は前記第2の変圧器の前記第2の側に結合されかつ前記第2の入力手段から分離され、前記第2のビデオ信号は前記第2の変圧器の前記第2の側に直接的に与えられる、ネットワークインターフェース装置。
