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: The present invention relates to a signal processing device and a video display device having same. A signal processing device according to one embodiment of the present invention comprises: a decoder for decoding first video data from a first video source and second video data from a second video source to output decoded first video data and decoded second video data; a video quality processing unit for, when a common frame rate is set on the basis of a first frame rate of the first video data and a second frame rate of the second video data, outputting the first video data on the basis of the common frame rate; and a graphic processing unit for outputting the second video data on the basis of the common frame rate. Thereby, it is possible to process a plurality of video data in synchronization.
