Abstract
(EN)
A video distribution server is provided with an SSD, a counter, a determination unit, an output unit, a first distribution control unit and a second distribution control unit. The counter counts the number of distribution requests for content data recorded in the SSD. The determination unit compares counter values and determines whether requested content data belongs to priority data with high-ranking numbers of distribution requests. When first object content data that is an object of a first distribution request belongs to the priority data, the first distribution control unit reads the first object content data from the SSD and caches the first object content data in a second storage area of the output unit, and when receiving a third distribution request for the first object content data after caching the first object content data, distributes the first object content data cached in the second storage area.

L'invention concerne un serveur de distribution vidéo pourvu d'un SSD, d'un compteur, d'une unité de détermination, d'une unité de sortie, d'une première unité de commande de distribution et d'une seconde unité de commande de distribution. Le compteur compte le nombre de demandes de distribution pour des données de contenu enregistrées dans le SSD. L'unité de détermination compare des valeurs de compteur et détermine si des données de contenu demandées appartiennent à des données de priorité avec des nombres de classement élevé dans les demandes de distribution. Lorsque des premières données de contenu d'objet qui sont un objet d'une première demande de distribution appartiennent aux données de priorité, la première unité de commande de distribution lit les premières données de contenu d'objet dans le SSD et met en mémoire cache les premières données de contenu d'objet dans une seconde zone de stockage de l'unité de sortie, et lors de la réception d'une troisième demande de distribution pour les premières données de contenu d'objet après mise en cache des premières données de contenu d'objet, distribue les premières données de contenu d'objet conservées dans la seconde zone de stockage.

 ビデオ配信サーバは、SSD、カウンタ、判定部、出力部、第1の配信制御部及び第2の配信制御部を具備する。カウンタは、SSDに記録されるコンテンツデータに対する配信要求の回数をカウントする。判定部は、カウンタ値をそれぞれ比較し、要求されたコンテンツデータが配信要求回数が高順位の優先データに属するかを判定する。第1の配信制御部は、第1の配信要求の対象である第1の対象コンテンツデータが優先データに属する場合、第1の対象コンテンツデータをSSDから読み出して出力部の第2の記憶領域にキャッシュさせ、キャッシュさせた後に第1の対象コンテンツデータに対する第3の配信要求を受信した場合、第2の記憶領域にキャッシュされる第1の対象コンテンツデータを配信させる。
