Abstract

[PROBLÈMES] L'invention concerne un dispositif d'enregistrement, un programme de déplacement et un système d'enregistrement de contenu visant à éliminer un état de reproduction activé d'un contenu ayant une longueur dépassant une minute simultanément à une source de déplacement et une destination de déplacement. [MOYENS POUR RÉSOUDRE LES PROBLÈMES] Si un signal d'interrogation est entré à partir d'un dispositif d'enregistrement (100) autre qu'un second dispositif d'enregistrement (200) pendant le déplacement vers un second dispositif d'enregistrement (200), l'étape S40 sur la Figure 4 génère un signal de réponse dans l'état pour masquer l'existence du contenu devant être déplacé et émet le signal. Ainsi, pendant l'opération de déplacement, les dispositifs d'enregistrement autres que le second dispositif d'enregistrement (200) ne peuvent pas connaître l'existence du contenu à déplacer. En conséquence, il est possible d'empêcher un déplacement ou une copie du contenu devant être déplacé, vers un dispositif autre que le second dispositif d'enregistrement (200) et d'empêcher la reproduction du contenu devant être déplacé, dans le premier dispositif d'enregistrement (100).
