Abstract:
1. A method comprising: receiving a base view video stream, an extended view video stream, a stream type field, and information regarding stereoscopic characteristics for supporting a 3D broadcast service, wherein the base view video stream is 3D video component which is used for legacy 2D broadcast service and the extended view video stream is 3D video component added to the base view video stream to compose 3D video, wherein the base view video stream and the extended view video stream are encoded using different codecs, wherein said information regarding stereoscopic characteristics is indicated by one or more descriptors defined in Advanced Television Systems Committee ATSC Standard; identifying the stream type field, wherein a value of the stream type field indicates a type of codec for the extended view video stream and information as to whether a video stream related to said at least one of said one or more descriptors is the base view video stream or the extended view video stream; identifying said one or more descriptors, wherein said one or more descriptors are included in a Terrestrial Virtual Channel Table (TVCT) of a Program and System Information Protocol (PSIP) in ATSC type digital broadcast, wherein for the 3D broadcast service in which the extended view video is encoded using a codec different from the base view video, at least one of said one or more descriptors includes a stream_info_details field for the extended view video stream; and processing the base view video stream and the extended view video stream using said one or more descriptors.
