Claim:
1. A 3D service device, comprising: a receiving unit to receive a broadcast signal containing a 3D service, the 3D service including 3D view data and depth data of a first view point, and view synthesis information transmitted by at least one of a program map table (PMT), a terrestrial virtual channel table (TVCT), or a service description table (SDT); a service information (SI) processing unit to extract and decode the view synthesis information on the 3D service from the broadcast signal; a first processing unit to decode the 3D view data and the depth data of the first view point; a second processing unit to generate 3D view data of a second view point by using the 3D view data and the depth data of the first view point and the view synthesis information, wherein the second view point is a random view point selected by a receiver from the first view point; and an output formatter to generate and output 3D service data based on the 3D view data of the second view point generated by the second processing unit.
