IP3 2023 – Video Compression 1 (LOT 14645)

This lot is generally related to an improved video compression to provide additional services to users. Techniques are disclosed for a video compression by generating a reconstructed full resolution frame and coded data from an original full resolution frame and generating an unsampled reconstructed reduced spatial resolution frame and coded data for the unsampled reconstructed reduced spatial resolution frame. Also disclosed are techniques to determine a first deviation by comparing a characteristic in the reconstructed full resolution frame with one characteristic in the original full resolution frame and identify a second deviation. Further disclosed are techniques to output the coded data related to the reconstructed full resolution frame when the first deviation is less than the second deviation. The technology may be implemented in video compression systems, video encoding and decoding systems, video signal encoding systems, etc.
