Patent attributes
The present disclosure relates to the use of hierarchical algorithms to temporally interpolate enhanced reference pictures for use in video encoding and decoding. According to a first aspect, there is provided a method of generating enhanced reference pictures in a video encoding and/or decoding process, the method comprising: receiving one or more known reference elements of video data from a reference picture buffer; generating, using one or more hierarchical algorithms, one or more additional reference elements of video data from the one or more known reference elements of video data; and outputting the one or more additional reference elements of video data; wherein the generating the one or more additional reference elements of video data from the one or more known reference elements of video data comprises the use of temporal interpolation.
