摘要:
The present application discloses systems and methods for using DC change parameters in video coding. In one embodiment, the method includes the steps of: (a) obtaining a DC change parameter; (b) decoding encoded video data to obtain reconstructed pixel values; and (c) using the reconstructed pixel values, a filter, and the DC change parameter to obtain filtered reconstructed pixel values with a DC change.
