Introduction

Zhiqi Hao is a notable inventor based in Richmond Hill, Canada. He has made significant contributions to the field of video encoding, holding three patents that enhance the efficiency and effectiveness of video processing technologies.

Latest Patents

One of Zhiqi Hao's latest patents is titled "Content adaptive quantization strength and bitrate modeling." This invention discloses systems, apparatuses, and methods for generating a model that determines the quantization strength used when encoding video frames. A pre-encoder performs multiple encoding passes using different quantization strengths on either a portion or the entirety of one or more pre-processed video frames. The pre-encoder captures the bit-size of the encoded output for each of these passes. Based on this data, the pre-encoder generates a model that maps bit-size to quantization strength for encoding video frames. When the encoder begins the final encoding pass, it utilizes this model to map a preferred bit-size to a given quantization strength, ensuring that the specified bit-rate for the encoded bitstream is met.

Another significant patent focuses on "Controlling power consumption in video encoding based on information regarding static amount of an image frame." This invention provides an apparatus and methods for controlling power consumption in video encoding. It obtains information regarding the static amount of an image frame to be encoded before motion estimation is performed. The methods adjust the power consumption of the video encoder based on this information, optimizing energy use during the encoding process.
