AV1-Compatible Film Grain Modeling for HEVC Decoders

This is the authors' abstract. We don't add key points for this paper.

In this work, the AV1-compatible film grain modeling for the HEVC decoders has been carried out to use the existing AV1 film grain post-processing support. This is accomplished by providing estimated film grain parameters within the ITU-T Recommendation T.35 (ITU-T T.35) Supplemental Enhancement Information (SEI) message. According to extensive experimental results, significant bitrate savings of more than 50% are achieved for substantially the same subjective video presentation quality.
