Apparatus and method for 3D broadcasting service in broadcasting system combined with mobile broadcasting

A receiving method of a broadcasting system, the receiver comprising:

• decoding a first image signal in a fixed broadcasting signal;
• decoding a second image in a mobile broadcasting signal;
• and
• composing the first image derived from the fixed broadcasting signal and the second image derived from the mobile broadcasting signal for a 3D image using side information,
• wherein the first image corresponds to one of a left image and a right image of the 3D image,
• wherein the second image corresponds to the right image when the first image corresponds to the left image of the 3D image, and the second image corresponds to the left image when the first image corresponds to the right image of the 3D image,
• wherein the side information is used to compose the first image derived from the fixed broadcasting and the second image derived from the mobile broadcasting signal for reproducing the 3D image.

A method of providing a three-dimensional (3D) broadcasting service, the method comprising:

• encoding one image for a 2D fixed broadcasting;
• encoding the other image for a 2D mobile broadcasting;
• generating a first data stream for the encoded one image based on a transport stream;
• and
• generating a second data stream for the encoded the other image based on an internet protocol;
• wherein the first data stream is transmitted via the 2D fixed broadcasting, and the second data stream is transmitted via the 2D mobile broadcasting,
• wherein side information is transmitted either 2D fixed broadcasting or 2D mobile broadcasting,
• wherein the side information is used to compose the first image derived from the fixed broadcasting and the second image derived from the mobile broadcasting signal for reproducing the 3D image.
