A method of generating a 3-dimensional (3D) image datastream is provided. The method includes generating an elementary stream including an encoded bit string of 3D image data; generating at least one packetized elementary stream by packetizing the elementary stream; generating at least one section including service related information of the 3D image data; inserting 3D image reproduction information for reproducing the 3D image data into a program guide information section from among the at least one section; generating at least one transport stream packet for each of the at least one section and the at least one packetized elementary stream; and generating a transport stream by multiplexing the at least one transport stream packet.
