Abstract:
1. A method of processing a stereoscopic three-dimensional (3D) service in a digital broadcast receiver, the method comprising: receiving a transport stream (TS) including the stereoscopic 3D service and a Program Association Table (PAT); parsing the PAT based on a predefined packet identifier (PID) from the received TS; acquiring a Program Map Table (PMT) based on a PMT_PID field included in the parsed PAT; and processing the acquired PMT including a stream_type field and multiple descriptors associated with 3D service, wherein a base view video of service-compatible stereoscopic 3D services is signaled using the stream_type value 0x02, further an additional view video for 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 included in the received TS 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.
