Abstract

本発明は、互換性を保ちつつ、高速で双方向の通信を行うことができるようにする通信システム、送信装置、受信装置、通信方法、プログラム、および通信ケーブルに関する。 HDMI(R)ソース７１とHDMI(R)シンク７２とがCECライン８４および信号線１４１を用いて双方向のIP通信を行う場合、切り換え制御部１２１は、データの送信時において、スイッチ１３３により変換部１３１からの差動信号を構成する部分信号が選択され、データの送信時において、スイッチ１３３によりレシーバ８２からの差動信号を構成する部分信号が選択されるようにスイッチ１３３を制御し、CECライン８４だけを用いて双方向の通信を行う場合、切り換え制御部１２１は、スイッチ１３３によりHDMI(R)ソース７１またはレシーバ８２からのCEC信号が選択されるように、スイッチ１３３を制御する。本発明は、たとえばHDMI(R)に適用することができる。
