Problems solved by technology
Therefore, the method for constructing stereoscopic video constructed from the left and right video respectively as two independent elementary streams has limitations in delivering stereoscopic video using the existing MPEG-2 transport stream
Furthermore, when stereoscopic video is constructed from a single elementary stream, left and right videos are composited to be constructed from a single video, and thus stereoscopic video can be transmitted using an existing MPEG-2 transport stream, but the transmitted video cannot be captured. Composite image construction information, which leads to limitations in identifying and processing transmitted composite image construction information that is 2D video rather than stereoscopic video

Embodiment Construction
[0024] Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In describing exemplary embodiments of the present invention, well-known functions or constructions will not be described in detail since the description would unnecessarily obscure an understanding of the present invention.
[0025] It will be understood that in this specification, when an element is simply referred to as being "connected to" or "coupled to" another element and not "directly connected to" or "directly coupled to" another element, it may be "connected directly to" or "coupled directly to" another element. "directly connected to" or "directly coupled to" another element, or may be connected or coupled to another element with other elements in between. In addition, in the present invention, "comprising" a specific configuration will be understood to mean that additional configurations may also be included within the scope of...

Disclosed are a signaling method for a stereoscopic video service and an apparatus using the method. An image decoding method comprises: a step of determining a field value based on a broadcast service type and a display mode in decoding a program level descriptor; and a step of determining an encoded stream type, whether an elementary stream is a reference stream, whether the elementary stream is a left-eye image or a right-eye image, additional image upsampling information and information on a subsampled line. Thus, efficiency of encoding / decoding an additional image for a stereoscopic video content may increase.
Description
technical field [0001] The present invention relates to a signal transmission method for a stereoscopic video service and a device using the same, and more particularly, to a decoding method and a decoding device. Background technique [0002] Humans receive 80% or more of information through their eyes. The transmission of information by vision takes up a very important part of the human being. Stereoscopic video is video that provides a sense of reality when humans can actually feel it, providing depth perception and presence together to 2D video. As a method for providing the information, three-dimensional stereoscopic techniques such as depth map information and stereoscopic video have been developed. The depth map information uses depth information to provide a stereoscopic effect on a two-dimensional video, but it is difficult to obtain accurate depth information. As a result, the depth map information has not been widely used. [0003] The left and right two-dimen...
