Latest Patents

Ueguri holds a patent for an "Error correction system in a teletext system." This invention focuses on an error correction system for a difference set cyclic (272, 190) code, which includes 190 data bits and 82 test bits in a packet. The system improves the transmission of data during the vertical blanking interval of a television signal. It features a buffer memory that stores both original and corrected data, along with an error correction circuit that includes a syndrome register, a majority circuit, and a data register. Notably, the data transfer between the buffer memory and the error correction circuit is achieved through wired logic hardware, eliminating the need for software operation time of a programmed computer. This innovation ensures that computer operation time is not wasted on error correction tasks. Additionally, a correction number counter is integrated to count the number of corrected bits, which helps in adjusting the threshold level for determining the reception signal and managing the error correction operation.
