要約
(EN) [Problem] To provide a server device that, when using ABS technology to deliver content to a client, is capable of specifying an alternative means if the client is unable to play said content. [Solution] Provided is a server device provided with a storage unit and a communication unit. In the storage unit, access information for accessing each of a plurality of sub-segments each constituting encoded data obtained by encoding the same content at a different bit rate is stored together with information on alternative content to play on a client device if said client device is unable to play the aforementioned content. The communication unit transmits the aforementioned access information to the content-playing client device in response to a request therefrom.
(FR) Le problème décrit par la présente invention est de fournir un dispositif serveur qui, lorsqu'il utilise la technologie ABS pour distribuer un contenu à un client, peut spécifier un moyen alternatif si le client est inapte à lire ledit contenu. La solution selon la présente invention porte sur un dispositif serveur équipé d'une unité de mémoire et d'une unité de communication. Dans l'unité de mémoire, des informations d'accès permettant d'accéder à chacun d'une pluralité de sous-segments constituant chacun des données codées obtenues par codage du même contenu à un débit binaire différent sont mémorisées conjointement à des informations relatives à un contenu alternatif à lire sur un dispositif client si ledit dispositif client est inapte à lire le contenu mentionné précédemment. L'unité de communication transmet les informations d'accès mentionnées précédemment au dispositif client de lecture de contenu en réponse à une requête de celui-ci.
(JA) 【課題】ABS技術を用いてコンテンツをクライアントに配信する際に、クライアントでコンテンツを再生ができない場合の代替手段を指定することが可能なサーバ装置を提供する。 【解決手段】同一のコンテンツを異なるビットレートで符号化して得られる各符号化データを構成する複数のサブセグメントの各々にアクセスするためのアクセス情報に、該コンテンツがクライアント装置で再生できない場合に該クライアント装置で再生させる代替コンテンツの情報を記述して記憶する記憶部と、前記コンテンツを再生する前記クライアント装置の求めに応じて前記アクセス情報を該クライアント装置に送信する通信部と、を備える、サーバ装置が提供される。
