Problems solved by technology

Even in the case of this format, when the processed video signal is displayed by a 2D display device instead of a 3D display device, left and right video are displayed alternately, and it is therefore impossible to watch TV normally

Embodiment Construction

[0031] Since the present invention can be modified in various ways and has several exemplary embodiments, specific exemplary embodiments will be shown in the drawings and described in detail.

[0032] However, it should be understood that the present invention is not limited to these specific exemplary embodiments, but includes all modifications, equivalents, and substitutions included in the spirit and scope of the present invention.

[0033] The terms 'first', 'second', etc. used in the specification can be used to describe various components, but these components should not be construed as being limited to these terms. These terms are only used to distinguish one component from another. For example, a "first" component may be referred to as a "second" component, and a "second" component may be similarly referred to as a "first" component without departing from the scope of the present invention. The term "and / or" includes a combination of multiple items or any one of multi...

Abstract

The present invention relates to an apparatus and method for receiving 3D digital broadcasting which is frame-compatible and service-compatible with an existing display device, regardless of whether a 3D service scheme is a frame-compatible scheme or a service-compatible scheme. The apparatus can include: a broadcast signal receiving and demodulating unit for receiving and demodulating a broadcast signal; a demultiplexing unit for obtaining broadcast program information including a broadcast service scheme, an image format, or an encoded type of a basic stream, and extracting the basic stream from the demodulated transmission stream; and an image processing unit for performing image processing on the basis of the obtained broadcast program information and a display mode of a broadcast receiving apparatus set by a user, and then outputting an image signal to a display device. Accordingly, a user can receive a normal 3D digital broadcast service regardless of whether a display device in use supports the service as well as a broadcast service scheme and an image format.

Description

technical field [0001] The present invention relates to an apparatus and method for receiving 3D digital broadcasting, and more particularly, to an apparatus and method for receiving 3D digital broadcasting capable of receiving broadcasting based on a video mode of a received broadcasting signal and an apparatus for receiving broadcasting The display mode is used to construct the video signal, and the video signal is output to the 3D display device. Background technique [0002] Service modes for 3D digital broadcasting are mainly divided into a frame compatible mode and a service compatible mode. The frame compatible (frame compatible 3D) mode means a mode in which original resolutions of left and right videos are reduced and constructed into a single video frame, and is a 3D digital broadcasting service mode currently used all over the world. The main video formats used in frame compatibility mode are side-by-side and top-bottom. Side-by-side is a video format that const...
