Method for providing and recognizing transmission mode in digital broadcasting

摘要

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.

1. A method of processing a three-dimensional (3D) service in a digital broadcast receiver, the method comprising:
receiving a transport stream (TS) including 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, wherein the digital broadcast receiver is a television receiver.
