IMAGE DATA TRANSMISSION DEVICE, IMAGE DATA TRANSMISSION METHOD, IMAGE DATA RECEPTION DEVICE, AND IMAGE DATA RECEPTION METHOD

摘要

To enable a reception side to reliably and easily identify before performing decoding whether substreams are configured such that they are constituted by a single video stream or a plurality of video streams. When transmitting a container having a predetermined format which contains a base video stream including first image data and a predetermined number of items of second image data related to this first image data, specific information is inserted into a position in a layer of this container at which information related to the base video stream is located. When transmitting a container having a predetermined format which contains a base video stream including first image data and a predetermined number of extended video streams including a predetermined number of respective items of second image data related to this first image data, specific information is inserted into a position in a layer of this container at which information related to each of the predetermined number of extended video streams is located.
