Abstract
Pre-encoding noise parameterization techniques mitigate or eliminate banding and other graphical artifacts in video frames for decoding and presentation by a client device. For one or more input video frames, a quantization parameter associated with the input video frames is identified. Noise synthesis parameters are determined based on the identified quantization parameter, and the input video frames are encoded for transmission. The encoded video frames are transmitted to the client device along with the determined noise synthesis parameters, for use by the client device in generating synthetic noise to add to resulting video frames decoded by the client device.
