| Abstract: | The present invention relates to a method for selecting an appropriate mode when performing a new broadcast, such as a 3D stereo broadcast, a UHDTV broadcast, and a multi-view broadcast, among others, while maintaining compatibility with existing broadcasting channels in an MPEG-2-TS format for transmitting and receiving digital TV, and to a method for recognizing a descriptor. To this end, the present invention suggests providing the descriptor which is related to synthesizing left and right images using the type of stream, existence of the descriptor, and a frame-compatible mode flag. |

| Claim: | 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. |
| Claim: | 2. The method of claim 1 , wherein a frame containing combined left and right images is transmitted through a transmission band in the frame-compatible stereoscopic 3D service, and a left image frame and a right image frame are independently compressed and transmitted through a different transmission band in the service-compatible stereoscopic 3D service. |
| Claim: | 3. The method of claim 1 , wherein the second descriptor provides information on a resolution relationship between a right view resolution and a left view resolution of the stereoscopic 3D service. |
| Claim: | 4. The method of claim 3 , wherein the second descriptor provides information on a value of the right view resolution which is different with a value of the left view resolution and the value of the right view resolution has a value from one of ¾, ⅔ and ½ of the left view resolution. |
| Claim: | 5. The method of claim 1 , wherein the first descriptor and the second descriptor are located in the PMT differently from each other. |
| Claim: | 6. The method of claim 5 , wherein the first descriptor is located in a loop of a program_info_length field of the PMT and the second descriptor is located in a loop of an ES_info_length field of the PMT. |
