Abstract

La présente invention concerne, dans ses modes de réalisation, un dispositif et un procédé de réception, un dispositif et un procédé d'émission, et un système d'émission-réception. Le dispositif de réception selon les modes de réalisation est pourvu d'une unité d'obtention, d'une unité de réception et d'une unité d'édition. L'unité d'obtention obtient des informations de segment de publicité dans lesquelles une association est établie entre des informations d'identification de segment de publicité et une durée d'un segment de publicité, les informations d'identification de segment de publicité étant des informations d'identification pour déterminer, parmi des segments de publicité, un segment de publicité dont le contenu de publicité peut être remplacé, et le segment de publicité étant une durée de diffusion d'un contenu de publicité dans un programme de diffusion. L'unité de réception reçoit, en provenance d'un dispositif externe, un contenu de publicité de longueur variable pouvant être lu selon les informations de segment de publicité. L'unité d'édition édite le contenu de publicité de longueur variable en fonction de la durée du segment de publicité. Selon le dispositif de réception selon la présente invention, le cas où une durée d'un segment CM dans un programme de diffusion diffère d'une durée de lecture de CM adressable peut être réduit.
