Latest Patents

Po-Yen Su's latest patents include a "Method for rate-distortion optimized transform and quantization through a closed-form operation." This invention focuses on a system that classifies input frames as either key frames or non-key frames. It utilizes a rate model update unit to generate model parameters based on transform coefficients and bitrates from encoded key frames. The RDO transform and quantization unit processes the input frame to produce quantized transform coefficients. Additionally, he holds a patent for a "Rate control method of perceptual-based rate-distortion optimized bit allocation." This method determines whether an input frame is a key frame or non-key frame and generates rate-distortion points for key frames. It updates the R-D model of each basic unit and computes a quantization parameter based on the target bit rate.
