Abstract
(EN)
The objective of the present invention is to enable a process for obtaining display-use image data from transmission video data to be performed suitably on the receiving side when multiple types of transmission video data having a prescribed opto-electric conversion characteristic are transmitted while being switched. A video stream is obtained by performing an encoding process on transmission video data obtained by switching and transmitting multiple types of transmission video data having a prescribed opto-electric conversion characteristic. A container in a prescribed format containing this video stream is transmitted. Identification information indicating the type of transmission video data possessed by the video stream contained in the container is inserted in the container. The identification information is inserted at no less than a prescribed amount of time before the timing of the switch, so as to indicate the type of transmission video data after the switch.

La présente invention a pour but de rendre possible un processus afin d'obtenir des données d’image d’utilisation de dispositif d’affichage à partir de données vidéo de transmission et que ledit processus soit assuré de manière appropriée sur le côté réception lorsque de multiples types de données vidéo de transmission ayant une caractéristique de conversion opto-électrique prescrite sont transmis tout en étant commutés. Un flux vidéo est obtenu par mise en œuvre d’un processus de codage sur des données vidéo de transmission obtenues par commutation et transmission de multiples types de données vidéo de transmission ayant une caractéristique de conversion opto-électrique prescrite. Un contenant dans un format prescrit contenant ce flux vidéo est transmis. Des informations d’identification indiquant le type de données vidéo de transmission appartenant au flux vidéo contenu dans le contenant sont insérées dans le contenant. Les informations d’identification sont insérées à une quantité de temps n'étant pas inférieure à une quantité de temps prescrite avant la temporisation de la commutation, de façon à indiquer le type de données vidéo de transmission après la commutation.
