Disclosed is an apparatus and method for transmitting/receiving reference image data and 3D additional image data in 3D image data so as to provide a 3D image in a digital broadcasting system. In the method, a basic image and a 3D additional image in a 3D image of a 3D broadcasting service is processed in a stereoscopic image format of one of a side-by-side method and a top-down method. The basic image and the 3D additional image processed in the stereoscopic image format are encoded to a basic image stream and a 3D additional image stream. The encoded basic image stream and the encoded 3D additional image stream are multiplexed to a 3D image stream of a single stream using a dual stream method, and the multiplexed 3D image stream is then transmitted.

Provided is a method for transmitting a stereoscopic video in a digital broadcasting system, the stereoscopic video being composed of a left view and a right view. The method includes: generating information indicating that the video is stereoscopic, information about a composition type of the stereoscopic video, and additional information based on the composition type; and transmitting the stereoscopic video and the generated information. The composition type is to compose the stereoscopic video of a single or two encoding streams by using the left view and the right view. In the case of a single stream mode in which the stereoscopic video is composed of the single encoding stream, the additional information includes information about positions of the left and right views. In the case of a dual stream mode in which the stereoscopic video is composed of the two encoding streams, the additional information includes information indicating whether the respective encoding streams are the left view or the right view and information indicating correlation between the respective encoding streams.

A driving unit includes a timing controller, a data driver having a data processor and a switching circuit, and a gate driver. The timing controller outputs image data, a data control signal, a gate control signal and a switching signal. The data processor converts the image data into a data voltage based on the data control signal, and the switching circuit receives the data voltage and a common voltage having a predetermined period and outputs either the common voltage or the data voltage in response to the switching signal. The gate driver outputs a gate voltage in response to the gate control signal. The timing controller outputs the switching signal at a time point in a first half period of a transition period of the common voltage, and the switching circuit outputs the common voltage at the time point.
