Latest Patent Applications

Ching-Lung Su's notable patent application is titled "REAL-TIME RATE-CONTROL METHOD FOR VIDEO ENCODER CHIP." This invention discloses a real-time rate-control method for a video encoder chip, wherein a BU-based RC algorithm is realized in a pipeline architecture. The RC algorithm is divided into an UpdateQP part arranged before the IME stage and an UpdateModel part arranged behind the entropy stage. When a currently processed frame contains a plurality of macro blocks, the bits used by several leading macro blocks and the remaining bits are predicted. Only the average value of the MADs of the preceding frame is stored in the memory. This approach greatly reduces memory consumption and allows for the prediction of the bit number required by the next frame. Furthermore, the invention defines a region of interest and automatically regulates the bit distribution ratio to enhance sharpness.

Conclusion

Ching-Lung Su's work in video encoding technology showcases his innovative spirit and dedication to improving efficiency in this field. His contributions, particularly through his latest patent application, highlight the potential for advancements in video processing technology.
