Abstract: The present invention relates to a transmitting apparatus, a transmitting method, and a receiving apparatus that are to preferably transmit content composed of a file. A transmission stream is transmitted to a reception side through a predetermined transmission path. In the transmission stream, a first transmission packet including transmission media and a second transmission packet including information related to the transmission media are time-division multiplexed. When the transmission media included in the first transmission packet is divided data of a file that composes predetermined content, identification information for identifying divided data included in the first transmission packet is inserted into the first transmission packet and the second transmission packet.

Abstract: Control information on a data broadcasting application for each delivery segment is distributed.An application service descriptor for each delivery segment is arranged into an MP table stored in a PA message on the side of a broadcast station. Each application service descriptor indicates information on one application type and priority of the application type. A receiver further selects a specific MH-AIT and data transmission message, on the basis of the priority for each application type, indicated with the application service descriptor, and a default AIT flag.

Abstract: To reduce the transport amount of MMT data transport control signaling.Detailed information regarding files under a directory agreeing with an MPU, is not transported in a DDMT, and detailed information regarding items under the MPU agreeing with the directory is not transported in a DAMT. A file describing the detailed information regarding the items under the MPU agreeing with the directory, is described as one item and is passed to the MPU so that transport is performed. In addition, an MPU node descriptor indicating that the MPU agrees with the directory, is arranged into the DAMT so that matching with the directory is performed.
