Abstract:
(EN) The present invention guarantees, without changing a display timing of text information about a subtitle, a correlation with a system timing when transmission is performed, and enables subtitle display at an appropriate timing on a reception side. According to the present invention, a packet, the payload of which includes a document of text information about a subtitle having display timing information, is generated and transmitted in synchronization with a sample time period. In the header of the packet, a timestamp for a first time axis indicating the start time of the corresponding sample time period is included. In the payload of the packet, reference time information about a second time axis related to the display timing and correlated with the start time of the corresponding sample time period is further included.
(FR) La présente invention garantit, sans changer une synchronisation d'affichage d'informations textuelles concernant un sous-titre, une corrélation avec une synchronisation de système lors de la transmission, et permet un affichage de sous-titre à un moment approprié sur un côté réception. Selon la présente invention, un paquet, dont la charge utile comprend un document d'informations textuelles concernant un sous-titre possédant des informations de synchronisation d'affichage, est généré et transmis en synchronisation avec une période de temps d'échantillon. Dans l'en-tête du paquet, un horodatage d'un premier axe temporel indiquant le temps de début de la période de temps d'échantillon correspondante est compris. Dans la charge utile du paquet, des informations de temps de référence concernant un second axe temporel concernant la synchronisation d'affichage et corrélées avec le temps de début de la période de temps d'échantillon correspondante sont également comprises.
(JA) サブタイトルのテキスト情報における表示タイミングを変えることなく伝送時のシステムタイミングとの関連性を保証し、受信側において適切なタイミングでのサブタイトル表示を可能とする。 サンプル期間に同期して表示タイミング情報を持つサブタイトルのテキスト情報のドキュメントがペイロードに含まれたパケットを生成して送信する。パケットのヘッダには、対応するサンプル期間の開始時刻を示す第1の時間軸のタイムスタンプが含まれる。パケットのペイロードには、対応するサンプル期間の開始時刻に関連付けされた、表示タイミングに係る第2の時間軸の基準時間情報がさらに含まれる。
