Abstract

A digital broadcast receiving apparatus for providing an integrated service of a 2D image and a 3D image. The apparatus comprising 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.

Claims

1. A method comprising:

receiving one or more broadcast data streams of multi-view video coding (MVC) video for supporting a 3D broadcast service based on the MVC and a plurality of descriptors indicating information associated with the one or more broadcast data streams;

identifying whether the one or more broadcast data streams of the MVC video correspond to a MVC base view stream;

obtaining information related to association between MVC views and left or right eye by using at least one of the descriptors,

said at least one of the descriptors having a value that determines whether the MVC base view stream is associated with left eye view or right eye view;

obtaining information related to positions of the MVC views including at least one MVC extended view stream by using a Program Map Table (PMT),

the information related to positions of MVC views indicating an order of the MVC views in a horizontal direction; and

processing the broadcast data streams using the obtained information related to association between MVC views and left or right eye.

2. The method of claim 1, wherein said at least one of the descriptors includes first and second syntax elements indicating which view, left or right, has been assigned to the MVC base view stream through combination of the first and second syntax elements.

3. The method of claim 1, wherein said at least one of the descriptors is included in in a Program Association Table (PAT) or the PMT.

4. The method of claim 1, wherein the MVC base view stream is displayed on its own for a 2D service.

5. A method comprising:

encoding one or more broadcast data streams of multi-view video coding (MVC) video for supporting a 3D broadcast service based on the MVC and a plurality of descriptors indicating information associated with the one or more broadcast data streams; and

transmitting, to a receiver, the one or more broadcast data streams with the descriptors such that the receiver employs at least one of the descriptors to support the 3D broadcast services,

wherein information that indicates whether the one or more broadcast data streams of the MVC video correspond to a MVC base view stream is transmitted to the receiver,

wherein at least one of the descriptors has a value that determines whether the MVC base view stream is associated with left eye view or right eye view such that the receiver obtains information related to association between MVC views and left or right eye by using said at least one of the descriptors,

wherein a Program Map Table (PMT) has information related to positions of the MVC views including at least one MVC extended view stream, and

wherein the information related to positions of MVC views indicates an order of the MVC views in a horizontal direction.

6. The method of claim 5, wherein said at least one of the descriptors includes first and second syntax elements indicating which view, left or right, has been assigned to the MVC base view stream through combination of the first and second syntax elements.

7. The method of claim 5, wherein said at least one of the descriptors is included in in a Program Association Table (PAT) or the PMT.

8. An apparatus comprising:

a demultiplexing unit;

a 3D decoder; and

a processor, wherein the demultiplexing unit, the 3D decoder, and the processor cooperate with each other to;

receive one or more broadcast data streams of multi-view video coding (MVC) video for supporting a 3D broadcast service based on multi-view video coding the MVC and a plurality of descriptors indicating information associated with the one or more broadcast data streams;

identify whether the one or more broadcast data streams of the MVC video correspond to a MVC base view stream;

obtain information related to association between MVC views and left or right eye by using at least one of the descriptors,

said at least one of the descriptors having a value that determines the MVC base view stream is associated with left eye view or right eye view;

obtain information related to positions of the MVC views including at least one MVC extended view stream by using a Program Map Table PMT,

the information related to positions of MVC views indicating an order of the MVC views in a horizontal direction; and

process the broadcast data streams using the obtained information related to association between MVC views and left or right eye.

9. The apparatus of claim 8, wherein said at least one of the descriptors includes first and second syntax elements indicating which view, left or right, has been assigned to the MVC base view stream through combination of the first and second syntax elements.
