Abstract: front page image
(EN)An HDMI source device (14) comprises: a first communication device (10) adhering to the HDMI standards; a second communication device (11) adhering to the USB standards; an arbitration circuit (13) that implements the arbitration between the first communication device (10) and the second communication device (11); and an HDMI connector (15) that is connected to the arbitration circuit (13) and that is shared between the HDMI communication and the USB communication. The arbitration circuit (13) performs, in accordance with the voltage values of a plurality of terminals of the HDMI connector (15), such a control that causes the source device (14) to operate as one of a USB host device, a USB target device and an HDMI source device. When having received a power supply from an HDMI sync device (16), the source device (14) transmits a feeding request to the sync device (16). The sync device (16) receives the request and supplies, based on the request, a power to the source device (14).
(FR)Un dispositif source HDMI (14) comprend : un premier dispositif de communication (10) adhérant aux normes HDMI ; un second dispositif de communication (11) adhérant aux normes USB ; un circuit d'arbitrage (13) qui met en œuvre l'arbitrage entre le premier dispositif de communication (10) et le second dispositif de communication (11) ; et un connecteur HDMI (15) qui est connecté au circuit d'arbitrage (13) et qui est partagé entre la communication HDMI et la communication USB. Le circuit d'arbitrage (13) effectue, conformément aux valeurs de tension d'une pluralité de terminaux du connecteur HDMI (15), un contrôle qui amène le dispositif source (14) à fonctionner comme un dispositif hôte USB, un dispositif cible USB ou un dispositif source HDMI. Lorsqu'il reçoit du courant d'un dispositif de synchronisation HDMI (16), le dispositif source (14) transmet une demande d'alimentation au dispositif de synchronisation (16). Le dispositif de synchronisation (16) reçoit la demande et fournit, d'après la demande, du courant au dispositif source (14).
(JA) HDMIソース機器(14)に、HDMI規格に準拠した第1の通信デバイス(10)と、USB規格に準拠した第2の通信デバイス(11)と、第1の通信デバイス(11)と第2の通信デバイス(12)との調停を実施する調停回路(13)と、調停回路(13)に接続されてHDMI通信とUSB通信とに共用されるHDMIコネクタ(15)とを設ける。調停回路(13)は、HDMIコネクタ(15)の複数の端子の電圧値に応じて、当該ソース機器(14)がUSBホスト機器、USBターゲット機器、HDMIソース機器のうちのいずれかとして動作するように制御する。また、当該ソース機器(14)は、HDMIシンク機器(16)から電源供給を受けたいとき、シンク機器(16)に給電リクエストを送信する。シンク機器(16)は、当該リクエストを受信し、それに基づいて電源をソース機器(14)に供給する。
