Latest Patents
Chieh Kai Kao holds a patent titled "Method for rate-distortion optimized transform and quantization through a closed-form operation." This invention is directed towards a rate-distortion optimized (RDO) transform and quantization system. The system includes a frame classification unit that classifies an input frame as either a key frame or a non-key frame. Additionally, a rate model update unit generates model parameters based on transform coefficients and bitrates from encoded key frames. The RDO transform and quantization unit processes the input frame to produce a quantized transform coefficient according to the model parameters. A frame buffer is utilized to store previous frames, which aids in estimating the bitrate.
