Abstract:
1. A method of transmitting a stereoscopic three dimensional (3D) service in a digital transmitter, the method comprising: encoding video data of the stereoscopic 3D service; multiplexing the encoded video data with signaling data; and transmitting a transport stream (TS) comprising the multiplexed data to a digital broadcast receiver, wherein the signaling data comprises a Program Map Table (PMT) including a stream_type field and multiple descriptors associated with 3D service, and a base view video of service-compatible stereoscopic 3D services is signaled using the stream_type value 0x02, further an additional view video for the service-compatible stereoscopic 3D services is signaled using the stream_type value 0x22 or 0x23, wherein a first descriptor among the multiple descriptors associated with 3D service comprises information identifying whether the stereoscopic 3D service is either a frame-compatible stereoscopic 3D service, or a service-compatible stereoscopic 3D service, and wherein a second descriptor among the multiple descriptors associated with 3D service provides information related to the service-compatible stereoscopic 3D service, further the second descriptor is included for both the base view video and the additional view video in the PMT for programs that support the service-compatible stereoscopic 3D service, the additional view video's stream_type value being 0x22 or 0x23.
