A method of synchronizing reference image with additional image in digital broadcasting includes generating at least one frame having predetermined identifier for providing notice of the start time of the reference image to receiver in advance; and transmitting at least one frame having the predetermined identifier to the receiver. Alternatively, the method of synchronizing reference image with additional image of includes generating signaling information containing additional image interlocking information at a transmission side in order to prepare for the additional image interlocked with the reference image at a reception side in advance; and providing the signaling information to the receiver. Therefore, it is possible to accurately and effectively perform the synchronization of 3D reference image with 3D additional image stored in the receiver or a streamed 3D additional image.

An illumination normalizing apparatus and a method are disclosed. The illumination normalizing apparatus measures a discontinuity of each pixel of an input image, the discontinuity including a spatial gradient and a local inhomogeneity, produces a weight of each pixel from the discontinuity by using a transfer function, produces an estimated illumination by repeating a convolution operation on each weight, and subtracts the estimated illumination from the input image.

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.

The present invention relates to polycrystalline gallium-doped zinc oxide of which the power factor is improved due to increased gallium doping of same. Despite having a high carrier concentration, the Seebeck coefficient of Zn0.985Ga0.015O is higher than that of Zn0.990Ga0.010O, and this arises because of the effect of the density-of-states (DOS) effective mass. A steady increase in compression stress following gallium substitution occurs in the base portion of the conduction band DOS. The solubility limit of gallium in the zinc oxide matrix is increased because a low firing temperature accelerates chemical compression. Single phase n-type Zn0.985Ga0.015O exhibits a power factor of 12.5 μWcm−1K−2.
