The content receiving unit () receives IP packets (Ethernet frames) that include broadcast content. The assigning unit () assigns, based on a given method, received Ethernet frames to the A-layer and the B-layer that are different digital broadcast layers. The Ethernet frames assigned to the A-layer are encapsulated by the A-layer processing unit (), and transmitted to a terrestrial digital broadcast network together with encapsulation format information. Meanwhile, the Ethernet frames assigned to the B-layer are encapsulated by the B-layer processing unit (), and transmitted to the terrestrial digital broadcast network together with encapsulation format information.

Broadcast-content transmitting apparatus, broadcast-content receiving apparatus, broadcast-content transmitting method, broadcast-content receiving method, and program

A broadcast-content transmitting apparatus includes a content input unit () that receives frame data including a broadcast content and a ULE encapsulating unit () that performs a predetermined encapsulation process on the input frame data. The transmitting apparatus further includes an SNDU&#x2192;DDB unit () or an SNDU&#x2192;MODULE unit () that form the encapsulated frame data into a DDB, which is a predetermined block unit, generate a DII, which is information concerning the DDB, and output the DDB and the DII as a section based on a predetermined data carousel scheme and a transmitting unit () that transmits the section output from the SNDU&#x2192;DDB unit () or the SNDU&#x2192;MODULE unit () to a terrestrial digital broadcasting network.
