Title: The Innovative Contributions of Dong Liu
Introduction
Dong Liu is a prominent inventor based in Markham, Canada, known for his significant contributions to video encoding technology. With a total of 11 patents to his name, Liu has made remarkable advancements in the field, particularly in optimizing video processing techniques.
Latest Patents
Among his latest patents, Liu has developed a method for dynamic motion estimation parameter modification for video encoding. This innovation leverages unused bandwidth at a hardware encoder to generate motion estimation data. The processing unit includes a hardware encoder that performs an initial encoding job, determines motion estimation data for a rendered frame, and encodes that frame. Additionally, the pre-processing circuitry determines a set of motion estimation parameters based on encoder delay, allowing the hardware encoder to perform a second encoding job using these parameters.
Another notable patent is the quantization parameter map for video encoding with constant perceptual quality. This method involves receiving a portion of a video sequence and determining complexities for blocks of pixels. Quantization parameter values are selected based on these complexities and the visually perceived coding artifacts produced by the quantization parameter values. The blocks of pixels are then encoded and decoded, providing a portion of the video sequence for display.
