Latest Patents

Cheng Qian's latest patents include groundbreaking technologies. One of his notable inventions is a unified memory architecture for recording applications. This apparatus comprises a first circuit, a second circuit, and a disc. The first circuit is designed to extract video data as data blocks from an input signal and perform error correction on these data blocks using a delta syndrome based iterative Reed-Solomon decoding. The second circuit is configured to decode the corrected video data into a video format in one state, encode it in another state, and share an external memory between the two circuits. The disc is intended to store the encoded video data.

Another significant patent is the DVD EFM modulation architecture, which utilizes two passes to reduce circuit size. This method involves modulating a video input signal received into a modulation circuit. During the first modulation pass, a primary frame and a secondary frame are generated by inserting synchronization codes into the video input signal. The second modulation pass then generates a video output signal by modulating the input signal using values determined from the first and second frames.
