Abstract: A processing unit (PU) is configured to generate reference values based on previously displayed frames in order to decode encoded frames having one or more noise-based effects. To this end, the PU includes a noise effect circuitry configured to determine noise values associated with a previously displayed frame. The noise effect circuitry then subtracts respective noise values from the pixel values of the previously displayed frame to determine reference values for decoding an encoded frame. Further, the PU includes a decoder that decodes the encoded frame based on the determined reference values.

Abstract: A portable electronic device includes a video encoder. The video encoder is configured to receive a video frame. Responsive to the video frame including at least one of a salient object or a region of interest, the video encoder is further configured to partition the video frame into one or more tiles based on a location of the at least one of the salient object or the region of interest.

Abstract: The disclosed computer-implemented method for video encoding rate control can include governing, by at least one processor, a video encoding rate at least partly in response to video encoding quality information. The method can additionally include generating, by the at least one processor, an encoded video data bitstream based on input pixel data and according to the video encoding rate. The method can also include determining, by the at least one processor, the video encoding quality information based on reconstructed pixel data. Various other methods, systems, and computer-readable media are also disclosed.
