Abstract:
(EN) The present invention protects necessary videos and makes effective use of a storage unit. A processing unit (42) cyclically overwrites and stores sequentially inputted video data in a storage unit (28). A PING-change-amount acquisition unit (38) periodically transmits a survival verification request (packet from PING command) to an external device (18), and detects a response from the external device (18) to the PING command packet. An overall control unit (40) controls in a manner such that when a prescribed number of responses are not detected, a point in time obtained by going back a set interval of time is set as a first starting point for starting to protect the video data by removal from inputted video data to be overwritten, and when a prescribed number of responses from the external device (18) to the PING command packet are detected after starting to protect the video data, the protection on the inputted video data is removed after detection of the prescribed number of responses.
(FR) La présente invention protège des vidéos nécessaires et utilise efficacement une unité de stockage. Une unité de traitement (42) réécrit cycliquement et enregistre séquentiellement des données vidéo entrées dans une unité de stockage (28). Une unité d'acquisition d'ampleur de changement PING (38) transmet périodiquement une demande de vérification de survie (paquet de commande PING) à un dispositif externe (18), et détecte une réponse du dispositif externe (18) au paquet de commande PING. Une unité de commande globale (40) agit de telle sorte que, quand un nombre prescrit de réponses n'est pas détecté, un point temporel obtenu en reculant d'un intervalle temporel défini, est défini comme un premier point de départ pour commencer à protéger les données vidéo, en les supprimant des données vidéo entrées devant être réécrites et, quand un nombre prescrit de réponses du dispositif externe (18) au paquet de commande PING est détecté après que la protection des données vidéo a commencé, la protection des données vidéo entrées est supprimée après que le nombre prescrit de réponses a été détecté.
(JA)  必要な映像を保護しつつ記憶部の有効利用を図る。 処理部42は、順次入力される映像データを記憶部28に循環的に上書き記憶させ、PING変化量取得部38は、外部装置18へ定期的に生存確認要求(PINGコマンドによるパケット)を送信すると共に、外部装置18からのPINGコマンドによるパケットに対する応答を検知し、全体制御部40は、応答が所定回数検知されない場合に、設定された時間を遡った時点を、入力された映像データを上書きされる対象から除外する前記映像データの保護を開始する第1開始時点とし、映像データの保護を開始した後に外部装置18からのPINGコマンドによるパケットに対する応答を所定回数検知した場合に、応答を所定回数検知した後に入力された映像データを保護対象から外すように制御する。
