IMAGE DATA TRANSMISSION DEVICE, IMAGE DATA TRANSMISSION METHOD, AND IMAGE DATA RECEIVING DEVICE

摘要

A reception side is enabled to appropriately and accurately handle a dynamic variation in delivery content and to receive a correct stream. One or a plurality of video streams including a predetermined number of image data items are transmitted. Auxiliary information for identifying a first transmission mode in which a plurality of image data items are transmitted and a second transmission mode in which a single image data item is transmitted is inserted into the video stream. A reception side identifies a transmission mode of a received video stream and performs an appropriate process so as to acquire a predetermined number of image data items on the basis of auxiliary information which is inserted into the received video stream in both a 3D period and a 2D period, only in the 3D period, or only in the 2D period.
