Abstract: Disclosed are an audio processing apparatus and method including obtaining at least one substream and additional information by parsing a bitstream, obtaining at least one audio signal of at least one channel group (CG) by decompressing the at least one substream, and obtaining a multi-channel audio signal by de-mixing the at least one audio signal of the at least one CG, based on the additional information. The additional information includes a weight index offset identified based on an energy value of a height channel of the multi-channel audio signal and an energy value of a surround channel of the multi-channel audio signal.

Abstract: An image display apparatus is disclosed. The image display apparatus includes a panel configured to display an image, a backlight including a plurality of light sources configured to output light to the panel, a light source driver configured to drive the plurality of light sources, and a processor configured to control the light source driver, wherein the processor changes the turn on duty of a light source corresponding to a moving object area in an input image and changes the level of current flowing in the light source. Consequently, the definition and luminance of an image including a moving object may be improved.

Abstract: Disclosed is a signal processing device and an image display apparatus including the same. The signal processing device includes: a quality calculator configured to compare a previous frame image and at least a region of a current frame image, and calculate image type information based on a comparison result; an image quality setting unit configured to set an image quality based on the image type information; and an image quality processing unit configured to perform image quality processing according to the set image quality. Accordingly, it is possible to improve accuracy of image analysis and perform image quality processing according thereto.
