Latest Patents

One of Xiaodong Wu's latest patents is the "Multichannel video port interface using no external memory." This invention introduces a video line encapsulation protocol that allows multiple low-definition video streams to be combined into a single super frame of high-definition video data. Each super frame is constructed from individual lines of various lower-definition video input signals. The high-definition video frames include metadata in each line that identifies the video input source, line, and frame. This metadata enables the separation of super frames into their component input signals within a video processing digital signal processor.

Another significant patent is the "Method and apparatus for digital MTS receiver." This system and method describe an all-digital audio receiver for a BTSC MTS audio signal or other composite signals that are FM modulated. A preferred embodiment includes a digital FM demodulator that receives an analog-to-digital quantized SIF signal, performs demodulation, and outputs a composite audio signal. Additionally, a digital audio processor decomposes the composite audio signal into at least the SAP, stereo, and monaural signals for audio reproduction. In this embodiment, both the digital FM demodulator and the digital audio processor are implemented as an integrated circuit.
