Title: Xiaofeng Jiang and Dynamic Decoder Switching

Introduction

Xiaofeng Jiang is an inventor associated with Hangzhou, China, and ArcSoft Corporation Limited. His patent work addresses how software video players can adapt when decoding requirements change during playback.

Latest Patents

Jiang is named on one patent, 1 patent: “Dynamic Decoder Switch.” The invention describes a method for dynamically changing a software video player’s decoder. It learns about a change from a decoder filter’s input pin, records the states of the decoder and renderer filters, and stops those filters while leaving the source filter unchanged.

The method then sets output-pin parameters, including the decoding mode. If the decoder and renderer pins remain connected, it uses the ReconnectEX function to apply a new media type. If they are disconnected, it uses the Connect function to connect them and set the new media type. The method selects a suitable decoder core and restores the decoder and renderer filters to their original states.

Career Highlights

Jiang’s listed patent reflects work on video playback technology, particularly the coordination of decoder and renderer components during dynamic changes. He is associated with ArcSoft Corporation Limited, a company working in multimedia software.

Collaborations

The provided information lists Lingxiao Ma and Chao Jin as Jiang’s coworkers. It does not specify their roles in the patent or describe particular collaborative projects.

Conclusion

Xiaofeng Jiang’s patent focuses on maintaining adaptable video playback by changing decoder configurations while managing filter connections and restoring system states.
