Abstract: The present invention relates to a lithium-manganese composite oxide in which the size of the face angle (vertical angle) of a primary particle is adjusted, and a method for preparing the same. The lithium-manganese composite oxide in which the size of the vertical angle of the primary particle is adjusted, and the method for preparing the same according to the present invention may gently adjust the size of the vertical angle of the polygon that constitutes a primary particle having a shape of a convex polyhedron in the lithium-manganese composite oxide, thus preventing the formation of convex-concave portions at the surface of an electrode plate in the process of forming the electrode plate by means of rolling during the manufacturing of a battery, thereby having an effect of improving characteristics of the battery.

Abstract: An apparatus and method are provided for synchronizing a reproduction time of a time-shifted content with a reproduction time of a real-time content. The apparatus includes a tuner/demodulator which tunes broadcasting signals and demodulates the tuned digital broadcasting signals so as to output the broadcasting signals in forms of transport streams, a demultiplexer which demultiplexes the output transport streams so as to divide the transport streams into video data, audio data, and supplementary information and output the video data, audio data, and supplementary information, a data refining unit which removes unnecessary frames from the video data and the audio data, and an HDD which stores the video data and the audio data, from which the unnecessary frames are removed.

Abstract: In one aspect, a differential signal transfer method is provided which includes converting 2M?1 original signals into 2M?1 differential signal pairs, where M is an integer of 2 or more, and wherein each pair consists of a first differential signal and a second differential signal having opposite phases, and transferring the 2M?1 differential signal pairs to 2M signal lines such that each of the 2M signal lines includes overlapping differential signals among the first differential signals and the second differential signals of the 2M?1 differential signal pairs.

Abstract: Disclosed herein are an apparatus and method for extracting the aspect ratio of received broadcast content. The apparatus includes an image reception unit, a frequency detection unit, a determination unit, and an output unit. The image reception unit receives a digital image. The frequency detection unit detects the frequency of the predetermined region of the frame of the digital image. The determination unit determines the aspect ratio of the received digital image by comparing the detected frequency with a threshold value. The output unit outputs the aspect ratio of the received digital image based on the result of the determination.

Abstract: An apparatus to display an overlaid image includes an alpha-value-checking unit to check a 3D object having an alpha value among 3D objects of an overlay plane, a blending unit to blend the 3D object and the previously painted overlay plane based on a plurality of blending rules if the 3D object has a predetermined alpha value as a result of the check by the alpha-value-checking unit, and a rendering unit to render the blended 3D object and the previously painted overlay plane.
