Title (EN) RECORDING METHOD AND RECORDING DEVICE
(FR) PROCÉDÉ D'ENREGISTREMENT ET DISPOSITIF D'ENREGISTREMENT
(JA) 記録方法、及び、記録装置
Abstract:
(EN) A recording method comprises: acquiring a video stream including an independently decodable picture (S21); recording the acquired video stream onto a recording medium (S22); storing a value representing the data size of the picture in a storage unit, the data size being defined by a third GOP management table into which a first GOP management table and a second GOP management table are merged (S23); and converting the stored value either to a first value defined by the first GOP management table or to a second value defined by the second GOP management table and recording the converted value onto the recording medium (S25, S26).
(FR) L'invention concerne un procédé d'enregistrement qui consiste à : acquérir un flux vidéo comprenant une image décodable de manière indépendante (S21) ; enregistrer le flux vidéo acquis sur un support d'enregistrement (S22) ; stocker une valeur représentant la taille de données de l'image dans une unité de stockage, la taille de données étant définie par une troisième table de gestion GOP dans laquelle une première table de gestion GOP et une seconde table de gestion GOP sont fusionnées (S23) ; et convertir la valeur stockée soit à une première valeur définie par la première table de gestion GOP, soit à une seconde valeur définie par la seconde table de gestion GOP et enregistrer la valeur convertie sur le support d'enregistrement (S25, S26).
(JA) 記録方法は、独立して復号可能なピクチャを含むビデオストリームを取得し(S21)、取得されたビデオストリームを記録媒体に記録し(S22)、第一GOP管理テーブル及び第二GOP管理テーブルがマージされた第三GOP管理テーブルによって定義される、ピクチャのデータサイズを示す値を記憶部に記憶し(S23)、記憶された値を、第一GOP管理テーブルによって定義される第一の値、及び、第二GOP管理テーブルによって定義される第二の値のいずれかに変換して記録媒体に記録する(S25、S26)。
