Abstract
Methods and systems for bidimensional video processing comprise preprocessing the video signal in horizontal and vertical dimensions of the video signal to reduce an amount of information of the video signal by low pass filtering the video signal and removing pixels to obtain an information-reduced video signal; expanding the information-reduced video signal by an expander process to produce an upconverted video signal; and comparing the upconverted video signal to the original video input to generate a support signal based on a difference between the original video signal and the upconverted video signal. Further embodiments include at least one of storing and transmitting the information-reduced video signal and the support signal; and during post-processing, processing and combining the information-reduced video signal and the support signal to generate a full information duplicate of the video signal.
