Latest Patents

Jilles Ultee holds a patent for a "Start code for signalling bits." This invention pertains to an extended television signal that includes signalling bits for conveying control information to an extended decoder. The start code's main lobe of spectral energy is designed to reside in the lower spectral area of a baseband television signal, specifically below 2 MHz and preferably below 1.7 MHz. The start code is engineered to be (almost) DC-free, ensuring good aperiodic correlation properties. Additionally, it maintains a predetermined minimum bit Hamming distance to the data bits when shifted in the direction of the data bits following the start code. This innovation is crucial for improving the performance of television decoders.
