Dennis Lew, an accomplished inventor based in Toronto, CA, is known for his significant contributions to video encoding technology. He has been granted a patent that showcases his inventive prowess, particularly in enhancing video quality during transmission.
Latest Patents
Lew's most notable patent focuses on an “Efficient Quantization Parameter Prediction Method for Low Latency Video Coding.” This invention elaborates on systems, apparatuses, and methods for calculating a quantization parameter (QP) which is crucial for encoding video frames to align with a specified bit budget. The patent discusses how control logic associated with an encoder determines a complexity indicator reflective of the difficulty level in encoding prior video frames. This complexity indicator takes into account several factors, including variance, intra-prediction factors, and inter-to-intra ratios. Utilizing the preferred QP derived from the complexity indicator allows the encoder to execute fewer QP adjustments across frames, thereby enhancing the visual quality of the resulting encoded video bitstream.
