A 3D video data processing method of a broadcast receiver, comprising: receiving, by a receiving unit, a broadcast signal including 3D video data and 3D complementary video information, wherein the 3D video data include, on a base layer, half-resolution base-layer 3D video data coded with Advanced Video Coding, AVC, and, on an enhancement layer, enhancement-layer 3D video data for configuring a full-resolution image, wherein the 3D complementary video information includes type information indicating a configuration type of the enhancement-layer 3D video data and order information indicating a combination order of the base-layer 3D video data and the enhancement-layer 3D video data; parsing, by a 3D video information processing unit (20030, 20040), the 3D complementary video information; decoding, by a base video decoder, the half-resolution base-layer 3D video data; decoding, by a complementary video decoder, the enhancement-layer 3D video data for configuring a full-resolution image; and combining and formatting, by an output formatter, the base-layer 3D video data and the enhancement-layer 3D video data using the 3D complementary video information, thereby outputting a full-resolution 3D image, wherein the 3D complementary video information further includes subsampling information indicating whether or not filtering is performed during subsampling, codec type information indicating the type of video codec used for encoding the enhancement-layer 3D video data, horizontal size information, vertical size information, frame rate information, filter information for implementing a filter used during an interpolation procedure, and perspective information indicating the image of which perspective is displayed first. receiving, by a receiving unit, a broadcast signal including 3D video data and 3D complementary video information, wherein the 3D video data include, on a base layer, half-resolution base-layer 3D video data coded with Advanced Video Coding, AVC, and, on an enhancement layer, enhancement-layer 3D video data for configuring a full-resolution image, wherein the 3D complementary video information includes type information indicating a configuration type of the enhancement-layer 3D video data and order information indicating a combination order of the base-layer 3D video data and the enhancement-layer 3D video data; parsing, by a 3D video information processing unit (20030, 20040), the 3D complementary video information; decoding, by a base video decoder, the half-resolution base-layer 3D video data; decoding, by a complementary video decoder, the enhancement-layer 3D video data for configuring a full-resolution image; and combining and formatting, by an output formatter, the base-layer 3D video data and the enhancement-layer 3D video data using the 3D complementary video information, thereby outputting a full-resolution 3D image, wherein the 3D complementary video information further includes subsampling information indicating whether or not filtering is performed during subsampling, codec type information indicating the type of video codec used for encoding the enhancement-layer 3D video data, horizontal size information, vertical size information, frame rate information, filter information for implementing a filter used during an interpolation procedure, and perspective information indicating the image of which perspective is displayed first.
