Abstract: The present disclosure relates to a signal processing device and an image display apparatus including the same. A signal processing device according to an embodiment of the present disclosure includes: an input interface to receive an image signal; a first image processor to generate first image frame data based on the image signal; a second image processor to generate second image frame data scaled down from the first image frame data based on the image signal; and an output interface to receive the first image frame data from the first image processor and the second image frame data from the second image processor and to output the first image frame data and the second image frame data, wherein the first image frame data output from the output interface is more delayed than the second image frame data output from the output interface. Accordingly, a timing controller may accurately and rapidly perform signal processing for a panel.

Abstract: An image display apparatus including the same are disclosed. A signal processing device of the present disclosure includes a decoder to decode data encoded based on at least two different coder-decoders, a buffer memory, and a controller to control the decoder and the buffer memory, wherein the controller controls the decoder to divide the buffer memory into a first storage space and a second storage space based on a codec change signal being received, and manages input or output of data of the first and the second storage space in parallel or simultaneously. Accordingly, it is possible to change codecs in real time without delay when codec change is required and to provide content without interruption of a screen to a user.

Abstract: The present disclosure relates to a signal processing device and an image display apparatus including the same. The signal processing device includes a synchronizer configured to perform Fourier transform based on the received baseband signal, and an equalizer configured to extract a pilot signal from a signal from the synchronizer, to calculate a channel transfer function value of the extracted pilot signal, and to selectively perform time interpolation based on the calculated channel transfer function value. Thus, time interpolation is selectively performed based on the channel.
