Title: Innovations by Crystal Sau
Introduction
Crystal Sau is an accomplished inventor based in Markham, Canada. She has made significant contributions to the field of video encoding, holding a total of four patents. Her work focuses on enhancing the efficiency and effectiveness of video processing technologies.
Latest Patents
One of her latest patents is titled "Dynamic motion estimation parameter modification for video encoding." This invention leverages unused bandwidth at a hardware encoder to generate motion estimation data. The processing unit includes a hardware encoder that performs a first encoding job, determines motion estimation data for a rendered frame, and encodes the rendered 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 "Palette mode video encoding utilizing hierarchical palette table generation." This invention encodes an image portion by recursively partitioning it into a hierarchy of levels. The encoder generates a palette table for each bottom-level block based on the pixels of the associated block. For each higher level, the encoder selects palette colors based on the palette colors from the lower levels, ultimately generating a color index map and encoding the portion using the final palette table.
