Method and apparatus for processing and receiving digital broadcast signal for 3-dimensional display

摘要

The disclosed method for processing a digital broadcast signal for a 3-dimensional, 3D, service comprises encoding video data for the 3D service into a video stream, the video data comprising a left picture and a right picture for a 3D image, generating the broadcast signal having the video data and service information for the 3D service, the service information including video depth range descriptor indicating a minimum disparity and a maximum disparity that occur during a given time window of the video stream, wherein the minimum disparity and the maximum disparity are a minimum difference and a maximum difference between horizontal positions of a pixel representing a same point in space in the left and right views of 3-dimensional image, respectively, and transmitting the digital broadcast signal for the 3D service.

主权项

1. A method for receiving a digital broadcast signal for a 3-dimensional, 3D, service, the method comprising:
receiving the broadcast signal having first video data carrying left views for the 3D service, second video data carrying right views for the 3D service and 3D information for the 3D service, wherein the 3D service includes at least one 3D program in which at least one scene is defined, the 3D information include scene disparity information specifying a minimum disparity and/or a maximum disparity which occur during a given time, and the scene disparity information is applied for the 3D service during the scene, wherein the minimum disparity and the maximum disparity are a minimum difference and a maximum difference between horizontal positions of a pixel representing a same point in space in a left view and a right view of 3D image, respectively; decoding the video data; parsing the 3D information; and controlling on screen display (OSD) menu of an apparatus to be displayed on outer range of range between the minimum disparity and the maximum disparity of the scene disparity information.
