Title: Cheng-Xiong Zhang: Video Coding Inventor

Introduction

Cheng-Xiong Zhang is an inventor based in Plano, Texas, whose patent work focuses on video coding techniques. His listed portfolio includes 2 patents, and the supplied information identifies Future Wei Technologies, Inc. as his company.

Latest Patents

Zhang’s listed patents address methods for improving video compression and coding.

“Multiple Predictor Set for Intra Coding with Intra Mode Prediction” describes predicting an intra mode for a video block using group numbers and indices associated with modes used by neighboring blocks. When the predicted mode differs from the actual mode, the system codes and transmits information about the actual mode.

“Predictive Adaptive Scan Ordering for Video Coding” describes video-coding apparatuses that use an adaptive scan-order predictor alongside motion compensation, transformation, quantization, scanning, and entropy-coding components. The approach supports adaptive ordering in both encoding and decoding processes.

Career Highlights

The listed inventions reflect Zhang’s work on predictive techniques for video coding, including intra-mode prediction and adaptive scan ordering. Both patents describe ways to coordinate coding components and use prediction to represent video information.

Collaborations

The supplied information lists Nam Ling and Lingzhi Liu as Zhang’s coworkers. Their names are associated with his professional context, though specific roles or contributions to the listed patents were not provided.

Conclusion

Cheng-Xiong Zhang’s listed patent work centers on predictive methods for video coding, with inventions addressing intra-mode selection and adaptive scan ordering.
