Abstract
Embodiments are generally directed to ringing suppression in video scalers. An embodiment of a method includes receiving a stream of video data, received video data including sets of video data values, and storing a first set of video data values in a memory. A first set of scaled values for the set of video data values is determined based on a scaling technology, and a second set based on linear interpolation. The method includes detecting rate of change in amplitude for received video data, generating a mixing control signal based at least in part on the rate of change, mixing first set of scaled values and second set of scaled values based at least in part on mixing control signal to generate blended set of coefficients, and generating scaled video data output using the set of blended values.
