Zusammenfassung: | To provide a display control device, a display control method, and a program, capable of performing an authentication process quickly regardless of a type of source device.SOLUTION: A display control device 10 has a control unit (CPU14) for displaying on a display unit by processing an input signal input from a digital video signal terminal (HDMI terminal 11a, HDMI receiver 11). The control unit uses an authentication start signal (HDCP authentication start message (step S101)) among input signals to start an authentication process with a specified priority, and if the authentication process is not completed within a specified time T0, the predetermined priority is raised and the authentication process is performed again.SELECTED DRAWING: Figure 4
【課題】ソース機器の種類に関わらず、認証処理を素早く行うことができる表示制御装置、表示制御方法及びプログラムを提供する。【解決手段】表示制御装置10は、デジタル映像信号端子(HDMI端子11a、HDMIレシーバ11)から入力した入力信号を処理して表示部に表示する制御部(CPU14)を有し、制御部は、入力信号のうちの認証開始信号(HDCP認証開始メッセージ(ステップS101))により所定の優先順位で認証処理を開始して、所定時間T0内で認証処理が完了しない場合には、所定の優先順位を上げて認証処理を再度行う。【選択図】図4 |
