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.

Systems, methods, and non-transitory media are provided for dynamically switching frame rates without changing a display refresh rate. An example method can include receiving, from a display device associated with a computing device, a set of control signals indicating a display refresh rate implemented by the display device; adjusting a frame rate associated with application data from one or more applications executed on the computing device; synchronizing, based on the set of control signals, the adjusted frame rate with two or more display refresh cycles, each display refresh cycle being based on the display refresh rate; providing, to the display device, a first frame at the adjusted frame rate, the first frame being generated based on the application data; and displaying the first frame at the display device implementing the display refresh rate.

An image processing device including an image acquisition unit configured to acquire an image containing a subject via a lens unit; a distance information acquisition unit configured to acquire distance information indicating a distance to the subject; an auxiliary data generation unit configured to generate auxiliary data related to the distance information; a data stream generation unit configured to generate a data stream in which the image, the distance information, and the auxiliary data are superimposed; and an output unit configured to output the data stream to outside.
