At the NAB show, Yves Faroudja and his new startup showed off new technology designed to provide up to 50 percent reduction in video bit rates without reduction in image quality.
The Faroudja's scheme doesn't alter current compression standards (MPEG2, MPEG 4, HEVC). It's rooted in Faroudja's belief that such compression systems aren't using all the available redundancies to improve compression efficiency.
Under the new scheme, Faroudja introduces a new pre-processor (prior to compression) and post-processor (after compression decoding). "We take an image and simplify it; and that simplified image goes through the regular [standards-based] compression process," he explained. "But we never throw away information."
Instead, in parallel with the conventional compression path, Faroudja inserts what he calls a "support layer." This compresses signals not used in Faroudja's so-called simplified image. Together with the decompressed simplified image, the support layer helps reconstruct the original image in full resolution -- at a reduced bit rate.
Faroudja claims "a bit rate reduction of 35% to 50% for an equivalent image quality [and] a significant improvement of the image quality on low bit rate content."
