Title: TRANSMISSION APPARATUS, TRANSMISSION METHOD, RECEPTION APPARATUS, AND RECEPTION METHOD
Abstract:
The present invention enables excellent transmission of a video stream. The image data of each picture constituting moving image data is encoded as layers, and a video stream having the encoded image data of the picture for each of the layers is generated. A container of a prescribed format including the video stream is transmitted. A descriptor, in which a value necessary for decoding is described, is inserted in a fixed manner into the layers of the container. The value necessary for decoding is fixed to the value of a maximum level. An operation is facilitated on the transmission side, and the maximum level of the value necessary for decoding can be easily recognized in the layers of the container on the reception side.
