Patent attributes
A video decoder chipset comprises a video decoder function, an upscaler function and a combiner function. The video decoder function is configured to (i) decode encoded video data to generate decoded video data at a first level of quality, the encoded video data having been derived by an encoder using first video data at a second, higher level of quality and (ii) output the decoded video data for storage in a memory. The upscaler function is configured to (i) obtain the decoded video data from the memory and (ii) upscale the obtained decoded video data to generate second video data at the second level of quality. The combiner function is configured to (i) obtain residual data, the residual data having been derived by the encoder based on the first video data and the second video data, (ii) combine the second video data with the residual data to generate enhanced video data, and (iii) output the enhanced video data.
