Abstract:
(EN) The present technique relates to a reproduction device, a reproduction method, and a recording medium which enable a content having a wide brightness dynamic range to be displayed with appropriate brightness. A reproduction device of one aspect of the present technique reads second coded data relating to an extended video that is a second brightness range of video from a recording medium on which, out of first coded data relating to a standard video that is a first brightness range of video and the second coded data, the second coded data is recorded, and communicates with a display device that is able to display the extended video to thereby acquire identification information relating to the display device. The reproduction device acquires brightness adjustment data used to adjust the brightness of the extended video and corresponding to the specifications of the display device on the basis of the identification information relating to the display device, adjusts the brightness of the extended video obtained by decoding the second coded data on the basis of the brightness adjustment data, and outputs the extended video with brightness characteristic information indicating the brightness characteristic of the extended video to the display device. This technique is applicable to a player who reproduces a content.
(FR) La présente invention concerne un dispositif de reproduction, un procédé de reproduction et un support d'enregistrement qui permettent d'afficher avec une luminance appropriée un contenu ayant une large plage dynamique de luminance. Selon un aspect de cette invention, un dispositif de reproduction lit des secondes données codées relatives à une vidéo étendue qui a une seconde plage de luminance à partir d'un support d'enregistrement qui contient les secondes données codées parmi des premières données codées se rapportant à une vidéo standard qui a une première plage de luminance et des secondes données codées, et qui communique avec un dispositif d'affichage pouvant afficher la vidéo étendue afin d'acquérir des informations d'identification liées au dispositif d'affichage. Ledit dispositif de reproduction acquiert, sur la base des informations d'identification liées au dispositif d'affichage, des données de réglage de luminance servant à régler la luminance de la vidéo étendue et correspondant aux spécifications du dispositif d'affichage, il règle, en fonction des données de réglage de luminance, la luminance de la vidéo étendue obtenue par décodage des secondes données codées, et il transmet au dispositif d'affichage la vidéo étendue accompagnée d'informations de caractéristique de luminance indiquant la caractéristique de luminance de la vidéo étendue. Cette invention s'applique à un lecteur qui reproduit un contenu.
(JA)  本技術は、輝度のダイナミックレンジが広いコンテンツを適切な明るさで表示させることができるようにする再生装置、再生方法、および記録媒体に関する。 本技術の一側面の再生装置は、第1の輝度範囲のビデオである標準ビデオの第1の符号化データと第2の輝度範囲のビデオである拡張ビデオの第2の符号化データのうちの第2の符号化データを記録した記録媒体から第2の符号化データを読み出し、拡張ビデオを表示可能な表示装置と通信を行うことによって、表示装置の識別情報を取得する。表示装置の識別情報に基づいて、拡張ビデオの輝度の調整に用いられる、表示装置の仕様に応じた輝度調整用データを取得し、第2の符号化データを復号して得られた拡張ビデオの輝度を、輝度調整用データに基づいて調整して、拡張ビデオの輝度の特性を表す輝度特性情報とともに表示装置に出力する。本技術は、コンテンツを再生するプレーヤに適用することができる。
