Abstract

A broadcast receiver and a 3D broadcast data processing method are disclosed. The processing method includes receiving a broadcast signal including system information (SI) and video data, parsing SI of a program, and determining whether the program provides a 3D broadcast service on the basis of the SI, extracting, if the program provides a 3D broadcast service, 3D broadcast data corresponding to the 3D broadcast service, and processing the 3D video data according to the SI. The broadcast receiver includes a receiving unit receiving a broadcast signal including SI and video data, an SI processor parsing system information of a program, and determining whether the program provides a 3D broadcast service on the basis of the SI, a demultiplexer extracting, if the program provides a 3D broadcast service, 3D broadcast data corresponding to a 3D broadcast service, and a video processing unit processing 3D video data according to the SI.

Claims6

Dependent claims

A three dimensional (3D) broadcast data processing method for use in a broadcast receiver, the method comprising:

receiving a broadcast signal including system information and video data;
parsing the system information of a program included in the broadcast signal;
determining that the program provides a 3D broadcast program based on the parsed system information;
extracting 3D broadcast data corresponding to the 3D broadcast program;
and
processing both a first elementary stream and a second elementary stream included in the extracted 3D broadcast data according to the parsed system information, the first elementary stream having video data for a base view and the second elementary stream having video data for an extended view,
wherein the system information of the program includes signaling information for the first and second elementary streams, the signaling information including stream type information and a stream-level descriptor for each of the first and second elementary streams,
wherein the stream type information indicates types of the first and second elementary streams, the stream type information indicating a video type for the first elementary stream and a specific data type for the second elementary stream,
wherein the stream-level descriptor comprises:
view information indicating whether the first elementary stream or the second elementary stream carries right images or left images;
and
stereoscopic composition type information indicating a ratio of a resolution of the base view carried in the first elementary stream compared to a resolution of the extended view carried in the second elementary stream in at least a horizontal direction or a vertical direction,
wherein the stream-level descriptor for the second elementary stream further comprises extended stream type information, the extended stream type information indicating a type and a codec of the second elementary stream, the type of the second elementary stream indicated by the extended stream type information is a video type, and
wherein the left images and the right images are transmitted via different video streams.
