Abstract
(EN)
This technology relates to a reception device and a reception method which make it possible to shorten the time that elapses before transmission control information is acquired. Provided is a reception device equipped with a control unit which, when a physical layer frame including transmission control information in a plurality of code words is received, performs control for confirming success of decoding while sequentially shifting a code to be decoded from among the plurality of code words code sequence by code sequence, and acquiring the transmission control information included in the plurality of code words obtained as a result of the decoding. This technology is applicable, for example, to data transmission corresponding to a predetermined broadcast system.

Cette technologie concerne un dispositif de réception et un procédé de réception qui permettent de raccourcir le temps qui s'écoule avant l'acquisition d'informations de commande de transmission. L'invention concerne un dispositif de réception équipé d'une unité de commande qui, lorsqu'une trame de couche physique comprenant des informations de commande de transmission dans une pluralité de mots de code est reçue, effectue une commande pour confirmer le succès du décodage tout en décalant séquentiellement un code à décoder parmi la pluralité de mots de code séquence de code par séquence de code, et acquérir les informations de commande de transmission incluses dans la pluralité de mots de code obtenus suite au décodage. Cette technologie est applicable, par exemple, à la transmission de données correspondant à un système de diffusion prédéterminé.
