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.
