DIGITAL BROADCAST RECEIVING METHOD PROVIDING TWO-DIMENSIONAL IMAGE AND 3D IMAGE INTEGRATION SERVICE, AND DIGITAL BROADCAST RECEIVING DEVICE USING THE SAME

摘要

PURPOSE: A digital broadcast receiving method for a 2D and 3D image integrated service and a digital broadcast receiving device thereof are provided to signal a channel providing a 3D image related to a 2D image during the provision of a 3D image service related to a 2D image service. CONSTITUTION: A PSIP(Program and System Information Protocol) or PSI/SI(Program Specific Information/Service Information) processor checks channel information about a video stream by using an extended service descriptor and checks PID(Packet Identifier) information about the video stream by using a 3D service location descriptor(S930,S940). A 3D image channel is selected according to the selection of a 2D image service(S942). The 3D image channel for a 2D image is selected according to the selection of a 3D image service(S950). [Reference numerals] (AA) Start; (BB) Select 2D; (CC) Select a watching mode; (DD) Select 3D; (EE) End; (S910) Filter a transport stream packet including table information, parse using table ID information, and obtain SDT; (S920) Read and store the service location descriptor and extended service descriptor of a 2D image channel using a service time; (S930) Check channel information about extended watching video stream by using the extended service descriptor; (S940) Check PID information about reference timing video stream and the extended watching video stream by a 3D service location descriptor including the extended timing video stream; (S942) Select a channel providing 2D images; (S944) Perform PID filter for the reference timing video stream and decode to corresponding elementary stream; (S946) Click a 2D image; (S950) Select a 3D image channel providing 3D images(service_type = 3DTV, number_of_views = 2); (S960) PID filter to the reference timing video stream and decode the corresponding elementary stream; (S970) PID filter to the extended timing video stream and decode the corresponding elementary stream; (S980) Format the decoded extended timing video stream and reference timing video stream to be matched to the 3D image display output
