Abstract
A broadcast receiver and a method for processing video data are disclosed. The method for controlling a three dimensional (3D) video display output of a broadcast receiver includes receiving a broadcast signal including a video stream, wherein the video stream includes a plurality of video stream sections having different view points, acquiring view point information indicating corresponding view points of the video stream sections, and controlling a three dimensional (3D) video display output of the video stream according to the obtained view point information.
Claims10
A method for controlling a three dimensional (3D) video display output of a broadcast receiver, the method comprising:
- receiving a broadcast signal including a base layer video stream and an enhancement layer video stream,
- wherein the base layer video stream includes first video stream sections having frames of left viewpoints for first scenes and second video stream sections having frames of right viewpoints for second scenes,
- wherein the first video stream sections and the second video stream sections are alternately multiplexed in the base layer video stream,
- wherein the enhancement layer video stream includes third video sections having frames of right viewpoints of the first scenes and fourth video sections having frames of left viewpoints for the second scenes, and
- wherein the third video stream sections and the fourth video stream sections are alternately multiplexed in the enhancement layer video stream;
- extracting a supplemental enhancement information (SEI) message from the base layer video stream, wherein the SEI message include viewpoint information specifying whether viewpoint of each of the frames corresponds to left viewpoint or right viewpoint;
- acquiring the viewpoint information from the SEI message;
- and
- controlling a 3D video display output using both of the base layer video stream and the enhancement layer video stream according to the acquired viewpoint information for a 3D view mode, and a 2D video display output using the base layer video stream for a 2D view mode.
A broadcast receiver comprising:
- a tuner configured to receive a broadcast signal;
- a demultiplexer configured to extract a base layer video stream from the broadcast signal,
- wherein the base layer video stream includes first video stream sections having frames of left viewpoints for first scenes and second video stream sections having frames of right viewpoints for second scenes,
- wherein the first video stream sections and the second video stream sections are alternately multiplexed in the base layer video stream,
- wherein the enhancement layer video stream includes third video sections having frames of right viewpoints of the first scenes and fourth video sections having frames of left viewpoints for the second scenes, and
- wherein the third video stream sections and the fourth video stream sections are alternately multiplexed in the enhancement layer video stream;
- a decoder configured to extract a supplemental enhancement information (SEI) message from the base layer video stream, wherein the SEI message include viewpoint information specifying whether viewpoint of each of the frames corresponds to left viewpoint or right viewpoint, and decode the extracted video stream;
- and
- a three dimensional (3D) display controller configured to control a 3D video display output using both of the base layer video stream and the enhancement layer video stream according to the viewpoint information for a 3D view mode, and a 2D video display output using the base layer video stream for a 2D view mode.
