Latest Patents
One of his latest patents is titled "Control of low frequency noise floor in upsampling." This invention involves a method and system for adjusting or controlling a noise floor of a filtered signal for low frequencies. In this process, a filtered digital signal, having M bits, is transformed into a one-bit XOR signal. This XOR signal is then added to the filtered signal to create a modified filtered signal. A selected number of least significant bits (LSB) of the modified filtered signal are removed to produce a dithered filtered signal, effectively reducing the noise floor for low frequencies.
Another significant patent by Chuanyou Dong is "Burst error correction on DVD data." This invention outlines a method and system for indicating that at least one row or column of a DVD data block has an uncorrectable number of errors. It involves marking or flagging the corrupted codewords of a codeword with defect detect signals. When a column or row of the data block contains more than a threshold number of errors, a selected number of distinguishable codeword values (DSVs) are associated with that column or row. This system interprets the presence of more than a threshold number of DSVs as an indication of uncorrectable errors in the data block.
