Title: Chao-Kung Yang: Innovator in Video Compliance Testing
Introduction
Chao-Kung Yang is a notable inventor based in Huntington Beach, California. He holds a total of nine patents, showcasing his significant contributions to the field of video technology. His work primarily focuses on MPEG compliance testing, which is crucial for ensuring the quality and reliability of video streams.
Latest Patents
One of Yang's latest patents is a method for MPEG compliance testing that designs test bit streams such that every frame of the expected decoded video is known. The process involves generating a test bit stream, decoding it, and storing it as an expected output decoded video. This test bit stream is then fed to the device under test, where it is decoded. The actual output video is compared with the expected decoded video on a frame-by-frame basis. Discrepancies in the test results can be visually examined by humans or by computers through a comparison of the two videos. During the generation of the test bit stream, for a given GOP structure, the subsequent P and B frames are determined by varying the selected testing MPEG parameter across its entire range of possible values while keeping other parameters constant.
Career Highlights
Chao-Kung Yang has had a distinguished career, working with prominent companies such as Hughes Electronics Corporation and DirecTV Group, Inc. His experience in these organizations has allowed him to refine his skills and contribute to significant advancements in video technology.
