Patent ID: 7983256

Claim:
A broadcast-content transmitting apparatus comprising: an input unit that receives an input of frame data that is input in real time, the frame data including broadcast content; an encapsulating unit that performs a predetermined encapsulation process on the frame data input to the input unit and forms a sub-network data unit; a packetizing unit that blocks the frame data encapsulated to be the sub-network data unit by the encapsulating unit, into a DDB (Download Data Block) being a predetermined block unit and generates a DII (Download Information Indication) being information concerning the DDB, the DDB including a module id that is an identifier for the DDB and a module version that is a version number of the DDB, the DII includes the module id and the module version for the DDB to which the DII corresponds, and the packetizing unit updates the module ids and the module versions of the DDB and the DII as the frame data is input; an encoding unit that outputs the DII followed by the DDB in given periodic intervals, where two DIIs having an identical combination of the module id and the module version are always transmitted in a row, and outputs a DDB that is present immediately after the module id and the module version of the DII change, the DDB and the DII output from the packetizing unit being output as a section based on a predetermined data carousel scheme; and a transmitting unit that transmits the section output from the encoding unit to a terrestrial digital broadcasting network.
