Abstract:
1. A method of transmitting a broadcast signal for 3-dimensional, 3D, service, the method comprising: encoding video data for a 3D service into a stream; and transmitting a broadcast signal including the encoded stream and service information for signaling the 3D service, wherein the service information comprises a first service information including a stream type for the at least one stream of the 3D service, a second service information including a service type for identifying the 3D service, and a third service information indicating that a future event is the 3D service, wherein the first service information includes a descriptor which signals existence of the 3D service, and the second service information includes stream information and 3D service structure information for the 3D service, wherein the stream information indicates that at least one stream for the 3D service is MPEG video stream or AVC video stream, and wherein the 3D service structure information indicates that the 3D service is a top-and-bottom service, a side-by-side service, or a full-frame 3D service, wherein the broadcast signal further includes a SEI (Supplemental enhancement information) message that includes a frame packing arrangement data specifying a 2D service portion in the broadcast signal in order to provide frame accurate signaling for a situation in which a temporal inconsistency between a current viewing mode and the first service information applied to the current viewing mode occurs when a viewing mode transits from 3D to 2D or 2D to 3D.
