Stereo image data transmitting apparatus and stereo image data receiving apparatus

摘要

[Object] To embed disparity information in a subtitle stream so that the disparity information can concurrently exist with subtitle information.;[Solution] In order to embed disparity information in a subtitle stream, “disparity data set segment” is newly defined as a DVB subtitle segment. With the use of this new segment, it is possible to embed disparity information in the subtitle stream so that the disparity information can concurrently exist with subtitle information. On the receiving side, the disparity information can be favorably acquired from the subtitle stream on the basis of “segment_type” that is identification information. Also, 1-bit flag information indicated by “disparity_data_association_flag” is newly defined in segment “page composition segment” including the subtitle information. This flag information indicates whether or not there is the presence of disparity information associated with this page. On the receiving side, it can be easily grasped whether or not there is disparity information associated with this page.

1. A stereo image data transmitting apparatus comprising:
a stereo image data output unit that outputs stereo image data including left-eye image data and right-eye image data; a superimposition information data output unit that outputs data of superimposition information to be superimposed on an image that is based on the left-eye image data and the right-eye image data; a disparity information output unit that outputs disparity information for giving disparity by shifting the superimposition information to be superimposed on the image that is based on the left-eye image data and the right-eye image data; and a transmitting unit that transmits the stereo image data output from the stereo image data output unit, the data of the superimposition information output from the superimposition information data output unit, and the disparity information output from the disparity information output unit, wherein the transmitting unit transmits at least the data of the superimposition information and the disparity information using the same elementary stream so that the data of the superimposition information and the disparity information can be identified by identification information, wherein the disparity information comprises a plurality of block-based disparity vectors and a plurality of group-based disparity vectors, the block-based disparity vectors including disparity vectors for respective blocks of pixels, and the group-based disparity vectors including disparity vectors for respective groups of the blocks.
