Abstract
A digital broadcast transmitting device is described that includes a packet generation unit configured to generate packetized elementary stream (PES) data by converting an inputted voice signal into an encoded voice signal and generating a voice stream packet including the encoded voice signal; a descriptor updating unit configured to update a component descriptor to include a component type identification (ID) and a change reservation ID, the component type ID indicating an encoding format of the encoded voice signal is MPEG surround format and the change reservation ID indicating a change of a format of the encoded voice signal to the MPEG surround format; a packetizing unit configured to generate section data by packetizing the component descriptor; a multiplexing unit configured to multiplex the PES data and the section data; and a modulation unit configured to modulate and transmit multiplexed data acquired from the multiplexing unit.
