A video decoding method, a video encoding method, and a related apparatus are provided. In the video decoding method, for a current target video frame in a target video, reference decoding parameters in a reference frame may be obtained from video frames that have been decoded before the target video frame, and a target resolution may be obtained based on a decoding indication parameter obtained based on (e.g., fusing) the reference decoding parameters. The current target video frame may be decoded by using the target resolution.

Disclosed are a signal processing device and an image display apparatus including the same. The signal processing device of an embodiment of the present disclosure includes: a quality calculator configured to calculate an source quality of an image signal received from an external settop box or a network; an image quality setter configured to set an image quality of the image signal based on the calculated source quality; and an image quality processor configured to perform image quality processing on the image signal based on the set image quality, wherein in response to the source quality of the received image signal being changed at a first time point, the image quality setter changes an image quality setting sequentially from a first setting to a second setting; and based on the image quality setting, the image quality processor performs image quality processing. Accordingly, flicker may be reduced when an image quality is changed due to a change in the source quality of the received image signal.
