| Claim: | 1. A method of processing a stereoscopic three-dimensional (3D) service in a digital broadcast receiver, the method comprising: receiving a broadcast signal comprising a transport stream (TS), wherein the TS includes a Program Association Table (PAT); parsing the PAT, which has a specific packet identifier (PID), from the received TS; acquiring a Program Map Table (PMT) based on a PMT_PID included in the parsed PAT; and processing the acquired PMT comprising both of at least two fields and at least two descriptors, wherein a first field among the at least two fields indicates a PID of the TS, and a second field among the at least two fields identifies a stream type of the TS, wherein a first descriptor among the at least two descriptors specifies a type of service that is provided, the service type corresponding to a two-dimensional (2D) service, a frame-compatible stereoscopic 3D service or a service-compatible stereoscopic 3D service, wherein a second descriptor among the at least two descriptors provides information related to the service-compatible stereoscopic 3D service that carries left and right views in separate video streams, the second descriptor further comprising: first data indicating that a video stream included in the TS is a base video stream or an additional view video stream: second data indicating that the video stream is a left view video stream or a right view video stream, and third data including an upsampling factor, required after the video stream is decoded, that identifies whether a coded resolution of the additional view video stream is the same as a coded resolution of the base video stream or different from the coded resolution of the base video stream. |
| Claim: | 2. The method of claim 1 , wherein the up sampling factor further identifies whether the coded resolution of the additional view video stream is a ½, ⅔, or ¾ coded resolution of the base video stream. |
| Claim: | 3. The method of claim 2 , wherein the second descriptor further comprises fourth data indicating that the additional view video stream is able to be used for the 2D video service. |
| Claim: | 4. The method of claim 3 , wherein the first field corresponds to an elementary PID of the PMT and the second field corresponds to a stream type of the PMT. |
| Claim: | 5. The method of claim 4 , wherein a location of the first descriptor within the PMT is different from a location of the second descriptor within the PMT. |
| Claim: | 6. The method of claim 5 , further comprising: receiving a PMT having the first descriptor or multiple descriptors, wherein the multiple descriptors have the first descriptor and either the second descriptor providing information related to the service-compatible stereoscopic 3D service or a third descriptor providing information related to the frame-compatible stereoscopic 3D services; and processing the PMT having the first descriptor or multiple descriptors, wherein the third descriptor is located in a loop following ES_info_length field in the PMT. |
