Abstract: Disclosed are a display apparatus and a method of controlling the display apparatus, the display apparatus including: a signal receiver which receives a signal containing video data for displaying a series of frames; a first data extractor which extracts first caption data from the signal; a data acquirer which acquires second caption data from the extracted first caption data; a second data extractor which extracts the video data from the signal; a buffering section which buffers the extracted video data; a synchronizer which synchronizes the acquired second caption data with frames corresponding to relevant caption data among frames of the buffered video data; and a display which displays the frame synchronized with the second caption data.

Abstract: Disclosed are an image processing apparatus, a voice acquiring apparatus, a voice recognition method and a voice recognition system. The image processing apparatus includes an image processor which processes an image signal, a communication unit which communicates with at least one electronic apparatus, and a controller which includes a voice recognition engine to recognize a voice command, and controls the communication unit to transmit a command to the at least one electronic apparatus corresponding to the voice command recognized by the voice recognition engine.

Abstract: A method for improving image quality, and an image signal processing apparatus and an AV device using the same are provided. In the method for improving image quality, processing image signals relating to improving the image quality can be adaptively performed based on the amount of movement of an input movie-image so that the image quality of the movie-image can be improved without breaking the image.

Abstract: A video processing apparatus including a display comprises a filter for receiving a video signal containing video information and ancillary information related to the video information and having a predetermined frequency. The filter passes a component corresponding to the frequency of the video signal. An ancillary information extractor extracts the ancillary information from the video signal passed by the filter. A video processor processes the video signal so that the ancillary information extracted by the ancillary information extractor is displayed on the display. The video processing apparatus is able to enhance the reliability of ancillary information extraction by removing the influence of noise.

Abstract: A video signal processing apparatus and video processing method are provided, which can reduce an influence of noise and enhance fineness of the image. A signal division unit divides a video signal into a low frequency component and a high frequency component of the video signal. A signal eliminating unit eliminates a component within a magnitude range of noise from the high frequency component of the video signal output from the signal division unit. A signal combining unit combines the low frequency component of the video signal output from the signal division unit and the high frequency component of the video signal from which the component within the magnitude range of noise is eliminated.

Abstract: A video display apparatus and a noise removal method thereof are provided. The video display apparatus includes a video processor which removes noise from an input video; and a controller which divides the input video into a plurality of areas according to settings, and controls the video processor to remove noise from each of the plurality of areas.
