Latest Patents

Ken-Ho Chang holds a patent for a "DS3 to ASI converter with reduced memory." This invention focuses on converting a DS3 transport stream to MPEG-2 packets over an ASI transport stream. The process involves extracting MPEG-2 packets along with PCR values, calculating a new PCR value to compensate for packet time shift, and replacing the extracted PCR value with the new PCR value prior to outputting MPEG-2 packets. The apparatus for processing a DS3 transport stream includes a DS3 receiver that outputs a data signal and clock signal. This receiver is designed to receive DS3 packets, discard null packets, and adjust PCR values before outputting the MPEG-2 packet. Notably, packets are output without storing each packet in a buffer, but the PCR value is stored in the buffer.
