His innovative approaches have the potential to enhance video processing efficiency and user experience.

Latest Patents

One of Guang Xu's latest patents is the "Fast Switching Hybrid Video Decoder." This invention presents techniques for seamlessly switching between a software decoder and a hardware decoder in a hybrid system. The process begins with receiving a video bit stream, which is then analyzed to determine its compatibility with the hardware decoder. If compatible, the stream is routed to the hardware decoder and stored in a first buffer. The hardware decoder processes the stream, storing reference frames in a second buffer. Conversely, if the stream cannot be decoded by the hardware decoder, it is directed to the software decoder. An instantaneous decoder refresh (IDR) frame is stored in the first buffer when decoded by the software decoder.

Another significant patent is the "Delay Tolerant Decoder." In this implementation, a network device receives a series of video frames over a specified time period. The device decodes these frames and stores them in memory along with their timestamps. It identifies any pause phenomena that exceed expected delays between decoded frames. The network device then forwards or displays the decoded frames, ensuring that each successive pair is spaced by a resultant delay period that is less than the duration of the pause phenomenon.
