Title: The Innovative Contributions of Jason Chan
Introduction
Jason Chan is a notable inventor based in Markham, Canada, recognized for his significant contributions to the fields of video and audio data compression. With a total of seven patents to his name, Chan has developed innovative technologies that enhance the efficiency and quality of digital media processing.
Latest Patents
One of Chan's latest patents is titled "Selectable Quantization in an Encoder." This invention presents a method for selectable quantization used in encoders for compressing video and audio data. The process begins by receiving discrete cosine transform data of an encoded signal. It continues by generating multiple quantization matrices based on a quantization table and various quantization scaling factors. The analysis of these matrices identifies the one that best matches reduced data content while maintaining acceptable video quality. Ultimately, the selected quantization matrix optimizes the encoding process.
Another significant patent is the "Raster Image Transformation Circuit Using Micro-Code and Method." This invention involves a circuit designed to transform a raster image stored within an image buffer. It includes memory that stores micro-code, a multiplier, an accumulator, and a sequential logic circuit. The multiplier forms a weighted pixel value by multiplying a given pixel value from the buffer with an associated weighting factor from the micro-code. The sequential logic circuit steps through the pixels and memory to present the necessary data to the multiplier, while the accumulator sums the weighted pixel values. This innovation allows for efficient scaling of raster images.
