With time buffer reproduction, which uses a fixed-length ring buffer, it is necessary to forcefully change the reproduction position in the case where reproduction is paused and the recording position within the ring buffer makes a revolution around the ring buffer and reaches the position of reproduction, and thus the pause function has no meaning. The present invention provides a time-shift buffer in which the recording position does not reach the reproduction position, by sequentially plural buffer areas in accordance with the recording progress and deleting the buffer areas in accordance with the reproduction progress.
Avec la reproduction à tampon temporel, qui utilise un tampon en anneau de longueur fixe, il est nécessaire de modifier fortement la position de reproduction si la reproduction est suspendue et la position d'enregistrement à l'intérieur du tampon en anneau accomplit une révolution autour du tampon en anneau et atteint la position de reproduction, la fonction de pause n'ayant ainsi aucun sens. La présente invention fournit un tampon à décalage temporel dans lequel la position d'enregistrement n'atteint pas la position de reproduction grâce à la création séquentielle de plusieurs zones de tampon en fonction de la progression de l'enregistrement et grâce à la suppression des zones de tampon en fonction de la progression de la reproduction.
