Image data transmission device, image data transmission method, and image data reception device

摘要

[Object] To enable a receiver compatible with MVC to adequately handle dynamic change in the contents of distribution and to perform correct stream reception.;[Solution] A broadcasting station 100 transmits a first transport stream TS1 and a second transport stream TS2 in a time-sharing manner. The TS1 includes the video elementary streams of a base view and a predetermined number of non-base views. The TS2 includes a video elementary stream of two-dimensional (2D) image data. Stream association information for associating the base view and a predetermined number of non-base views is inserted into the TS1. A receiver 200 recognizes that the TS1 has been transmitted, based on the stream association information, and also recognizes association between the base view and non-base views. The receiver 200 can adequately handle dynamic change of the TS1 and TS2, i.e., dynamic change in the contents of distribution, and perform correct stream reception.

1. An image data transmission device comprising:
a data output unit configured to output first image data, a predetermined number of second image data and/or meta data relating to this first image data; and a data transmission unit configured to transmit a transport stream; wherein said transport stream includes the packets obtained by packetizing a first elementary stream including first image data output from said data output unit, and a predetermined number of second elementary streams including a predetermined number of second image data and/or meta data output from said data output unit respectively; wherein said data transmission unit inserts stream association information for associating said first elementary stream with said predetermined number of second elementary streams into said transport stream; wherein said data transmission unit inserts M pieces (M is an integer of two or more) said stream association information into said transport stream; and wherein said M pieces of stream association information associate said first elementary stream with said second elementary stream within each set obtained by dividing said predetermined number of second elementary streams into M sets.
