Latest Patents

One of Jeng's latest patents is titled "Single-pass variable bit-rate control for digital video coding." This innovation involves an integrated circuit that enables single-pass, real-time digital image encoding using a digital signal processor. It allows for variable bit rate (VBR) control, which improves the quality of the decoded output. The technology includes a peak bit rate range for multiple groups of pictures (GOP) and an averaged bit rate limit for the encoded signal. The signal processor calculates various parameters, including perceptual weighting variables and effective bit rates for each GOP, ensuring optimal bit allocation for multiple pictures.

Another significant patent is "Multiple stage and low-complexity motion estimation for interframe video." This patent describes a digital signal processor that encodes video signals according to MPEG standards. It achieves multi-stage, low-complexity motion estimation for interframe video coding. The dual-stage motion prediction module processes a compressed bitstream through pixel-averaging and applies a Sum-Of-Absolute-Difference (SOAD) function to generate a minimum motion vector signal. This method enhances the accuracy of motion estimation, leading to improved video quality.
