Abstract
(EN) In the present disclosures, a source device (100) is provided with: an authentication state acquisition unit (205) that transmits to a sink device (120) an authentication state request (253) requesting the transmission of an authentication state (254) indicating whether or not authentication between the sink device (120) and a repeater device (140) has terminated normally, and that acquires the authentication state (254) transmitted from the sink device (120) in response to said authentication state request (253); and a content control unit (206) that controls in a manner so that the sink device (120) is not able to acquire content information (251) when it is indicated by the authentication state (254) that authentication between the sink device (120) and the repeater device (140) has not terminated normally.
(FR) La présente invention concerne un dispositif de source (100) équipé: d'une unité d'acquisition d'état d'authentification (205) qui transmet vers un dispositif récepteur (120) une demande d'état d'authentification (253) requérant la transmission d'un état d'authentification (254) indiquant si une authentification entre le dispositif récepteur (120) et un dispositif répéteur (140) a été complétée normalement ou non, et qui acquiert l'état d'authentification (254) transmis depuis le dispositif récepteur (120) en réponse à ladite demande d'état d'authentification (253) ; et d'une unité de commande de contenu (206) qui effectue une commande de sorte que le dispositif récepteur (120) ne soit pas capable d'acquérir une information de contenu (251) lorsqu'il est indiqué par l'état d'authentification (254) que l'authentification entre le dispositif récepteur (120) et le dispositif répéteur (140) n'a pas a été complétée normalement.
(JA)  本発明に係るソース機器(100)は、シンク機器(120)とリピータ機器(140)との間で認証が正常に終了したか否かを示す認証状態(254)の送信を要求する認証状態要求(253)をシンク機器(120)へ送信し、当該認証状態要求(253)に応じてシンク機器(120)から送信された認証状態(254)を取得する認証状態取得部(205)と、認証状態(254)によりシンク機器(120)とリピータ機器(140)との間で認証が正常に終了していないことが示される場合、シンク機器(120)がコンテンツ情報(251)を取得できないように制御するコンテンツ制御部(206)とを備える。
