Abstract
Methods and apparatuses for applying adaptive reduced resolution update (RRU) processing are disclosed herein. An apparatus may include an encoder configured to receive a video signal and selectively downsample a first component of the video signal in accordance with a first RRU coding mode and a second component of the video signal in accordance with a second RRU coding mode, based on respective types of the first and second components of the video signal. An apparatus may include a decoder configured to receive an encoded bitstream and provide a recovered residual based on the encoded bitstream. The decoder may be configured to selectively upsample a first component of the recovered residual in accordance with a first RRU mode and to selectively upsample a second component of the recovered residual in accordance with a second RRU mode to provide a reconstructed signal based on signaling mechanisms of the encoded bitstream.
