Abstract: The present invention relates to a signal processing device and an image display device including same. The signal processing device according to an embodiment of the present invention comprises: a streaming data processing unit for receiving streaming data, generating list information including information related to a plurality of first unit of data, on the basis of the received streaming data, and outputting the generated list information; and a decoder for receiving the list information and decoding the plurality of data of the first unit, on the basis of the list information, wherein the streaming data processing unit outputs data decoded by the decoder. Accordingly, the number of inter process communications can be reduced during signal processing of streaming data.

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.
