Abstract

A method of receiving broadcast data streams for supporting a broadcast service, wherein the broadcast data streams include a multi-view video coding (MVC) base view video stream and at least one a MVC extended view stream; identifying a stream type field and a priority_id field of the broadcast data streams using a table, wherein a value of the stream type field indicates a codec of the MVC base view video stream or the at least one MVC extended view stream, wherein the priority_id field indicates priority information on the broadcast data streams of multi-view video, and wherein a value of the priority_id field with respect to the MVC base view video stream is set to be equal to zero; processing the broadcast data stream using the identified stream type and the priority_id field to support the broadcast service.

Claims

1. A method comprising:

receiving broadcast data streams for supporting a broadcast service based on multi-view video coding (MVC),

wherein the broadcast data streams include an MVC base view video stream and at least one a MVC extended view stream;

identifying a stream type field and a priority _id field of the broadcast data streams using at least one of a Program Association Table (PAT), a Program Map Table (PMT), a Service Description Table (SDT), or an Event Information Table (EIT),

wherein a value of the stream type field indicates a codec of the MVC base view video stream or the at least one MVC extended view stream,

wherein the priority_id field indicates priority information on the broadcast data streams of multiview video, and

wherein a value of the priority _id field with respect to the MVC base view video stream is set to be equal to zero; and

processing the broadcast data stream using the identified stream type and the priority _id field to support the broadcast service.

2. The method of claim 1, further comprising:

obtaining information indicating whether or not a position of the at least one MVC extended view video stream is in a rightward direction or a leftward direction based on the MVC base view stream using at least one descriptor.

3. The method of claim 2, wherein the at least one plurality of descriptors further comprises additional values that indicate a descriptor tag and a descriptor length.

4. The method of claim 2, wherein the MVC base view video stream is displayed as left eye view or right eye view using the at least one descriptor.

5. The method of claim 1, wherein the at least one MVC extended view stream is encoded with an advanced codec and the MVC base view video stream is encoded with a 2D compatible codec.

6. An apparatus comprising:

a tuner for receiving broadcast data streams for supporting a broadcast service based on multi-view video coding MVC,

wherein the broadcast data streams include an MVC base view video stream and at least one a MVC extended view stream;

a demultipixer and a PSIP (Program and System Information Protocol) or PSI/SI (Program Specific Information/Service Information) processor for identifying a stream type field and a priority_id field of the broadcast data streams using at least one of a PAT, a PMT, a SDT, or an EIT,

wherein a value of the stream type field indicates a code of the MVC base view video stream or the at least one MVC extended view stream,

wherein the priority_id field indicates priority information on the broadcast data streams of multiview video, and

wherein a value of the priority_id field with respect to the MVC base view video stream is set to be equal to zero; and

a decoder for processing the broadcast data stream using the identified stream type and the priority_id field to support the broadcast service.

7. The apparatus of claim 6, wherein information indicating whether or not a position of the at least one MVC extended view video stream is in a rightward direction or a leftward direction based on the MVC base view stream is obtained using at least one descriptor.

8. The apparatus of claim 7, wherein the at least one plurality of descriptors further comprises additional values that indicate a descriptor tag and a descriptor length.

9. The apparatus of claim 7, wherein the MVC base view video stream is displayed as left eye view or right eye view using the at least one descriptor.

10. The apparatus of claim 6, wherein the at least one MVC extended view stream is encoded with an advanced codec and the MVC base view video stream is encoded with a 2D compatible codec.
