Digital broadcast receiving method providing two-dimensional image and 3D image integration service, and digital broadcast receiving device using the same
First Claim
1. A broadcast receiving apparatus, comprising:
- a demultiplexing unit configured to filter transport stream packets;
a 3D decoder configured to decode elementary streams;
a processor configured to recognize packet identifier PID information; and
a display unit configured to display 2D image data or 3D image data, wherein the demultiplexing unit, the 3D decoder, the processor, and the display unit cooperate with each other to;
obtain a Terrestrial Virtual Channel Table (TVCT) of a Program and System Information Protocol (PSIP) in Advanced Television Systems Committee (ATSC) type digital broadcast from a transport stream;
identify a service type of at least one channel among a first channel, a second channel, and a third channel using a service type field of the TVCT,wherein the first channel carries a 2D broadcast service, and the second channel and the third channel carry a 3D broadcast service, andwherein the second channel provides a stereoscopic image and the third channel provides a multi-view video coding (MVC) image; and
operate different view modes based on whether the first channel, the second channel, or the third channel is selected,wherein one of a base view video stream and at least one additional view video stream is decoded using a 2D compatible codec for supporting the first channel related to a 2D mode of the different view modes, andwherein the base view video stream and the at least one additional view video stream are decoded using different codecs for supporting the second channel and the third channel related to a 3D mode of the different view modes.

Abstract
A digital broadcast receiving apparatus for providing an integrated service of a 2D image and a 3D image. The apparatus comprising a demultiplexing unit configured to demultiplex a received digital broadcast signal; a PSIP or PSI/SI processor configured to extract at least any one of 3D service information related to a 2D image channel or service and 2D service information related to a 3D image channel or service from the demultiplexed digital broadcast signal; a decoder configured to decode an extension view video stream and a base view video stream from the demultiplexed digital broadcast signal; and an output formatting unit configured to format the extension view video stream and the base view video stream based on at least any one of the 3D service information and the 2D service information.
