Latest Patents
One of his latest patents is titled "Rate control for low latency video encoding and transmission." This innovative system decomposes pixel data into frequency bands before encoding. The frequency bands for a slice of a frame are buffered, allowing complexity statistics to be calculated across these bands prior to encoding. These statistics inform a rate control component that determines quantization parameters for modulating the encoder's rate for the current slice. The quantization parameters are calculated jointly to optimize the quality of displayed frames after decoder reconstruction and wavelet synthesis on a receiving device. Additionally, information from previously processed frames may be utilized alongside current slice statistics to refine the quantization parameters.
Another significant patent is "Block-based low latency rate control." This method employs a wavelet transform to decompose pixel blocks into subbands stored as wavelet blocks (WBs) for encoding. The quantization parameters for the subbands are estimated using a technique that minimizes wavelet-inverse distortion within a specified rate bound. Rate and distortion curves are generated for each subband, and a bisection search identifies points on these curves where the slope is consistent across all curves. The quantization parameters associated with these points represent the global minimizing QPs for the wavelet block.
