Latest Patents

One of his latest patents is the "Trellis decoder for real-time video rate decoding and de-interleaving." This invention allows for real-time decoding of high-rate input data exceeding 10 MHz, utilizing a compact layout without the need for generating very high-speed clocks. The architecture includes a branch metric generator feeding multiple parallel Add/Compare/Select modules, which then connect to a traceback processor. This design enables n-state Trellis decoding in real-time while simultaneously de-interleaving a multiplexed data stream. The invention also allows for complete traceback in one symbol period at video rates, providing flexibility in output error rate and traceback memory space.

Another significant patent is related to "DVB frame synchronization." This invention presents a method for synchronizing Digital Video Broadcasting (DVB) data using a temporary storage area that is smaller than the repetition rate of the sync pattern. The synchronization is achieved through correlation detection of the sync pattern, which has a fixed repetitive separation. This synchronization scheme is simple and can be implemented as an integrated circuit, using software and a microprocessor, or as discrete circuitry.
