Abstract

A digital broadcast receiving apparatus for providing an integrated service of a 2D image and a 3D image comprises: a demultiplexing unit configured to demultiplex a received digital broadcast signal; a PSIP or PSI/SI processor configured to extract at least any one of 3D service information related to a 2D image channel or service and 2D service information related to a 3D image channel or service from the demultiplexed digital broadcast signal; a decoder configured to decode an extension view video stream and a base view video stream from the demultiplexed digital broadcast signal; and an output formatting unit configured to format the extension view video stream and the base view video stream based on at least any one of the 3D service information and the 2D service information. When a selection of the 3D image service is input by a user, a 3D image channel or service providing a 3D image with respect to the 2D image channel or service based on the 3D service information may be selected, and when a selection of the 2D image service is input by the user, a 2D image channel or service providing a 2D image with respect to the 3D image channel or service based on the 2D service information may be selected. Accordingly, an integrated service of a 2D image and a 3D image can be provided in a digital broadcast.

Claims

1-17. -17. (canceled)

18. A method comprising:

receiving service information SI that provides information for a receiver to support 3D broadcast services,

said service information SI including a plurality of descriptors that provide information related to a broadcast data stream, and

said service information SI including a plurality of tables comprising a Program Association Table PAT, a Program Map Table PMT, a Service Description Table SDT, and an Event Information Table EIT;

identifying said plurality of descriptors in the received service information SI, said identified plurality of descriptors, which comprise at least one of a first descriptor having a value that indicates availability of services via terrestrial channels and a second descriptor having at least one value that indicates 3D service characteristics, being included in at least one of the Program Association Table PAT, the Program Map Table PMT, the Service Description Table SDT, and the Event Information Table EIT; and

processing the broadcast data stream using the received service information SI and at least one of the identified plurality of descriptors to support the 3D broadcast services.

19. The method of claim 18, wherein the second descriptor related to 3D service characteristics is included in the Service Description Table SDT.
