Title: Tetsuya Yasui: Innovator in Multimedia Data Communication
Introduction
Tetsuya Yasui is a prominent inventor based in Fukuoka, Japan. He has made significant contributions to the field of multimedia data communication, holding a total of 7 patents. His work focuses on improving the quality and efficiency of data transmission, particularly in environments where data integrity is crucial.
Latest Patents
Among his latest patents are a data receiving device, a data receiving method, and a computer product. In his data receiving device, time information is separated from received multimedia data. A first difference is calculated between two consecutive pieces of time information, and a second difference is calculated between the reception timings of these two consecutive time information. Jitter is calculated from the first and second differences, allowing for the adjustment of a clock that reproduces the multimedia data based on the calculated jitter. His communication system aims to enhance communication quality by accurately recreating reproduction timing at the receiving end, even when receiving variable bit rate (VBR) data or in cases of packet loss. A send rate recognition section identifies the send rate from a time stamp, while a memory stores the data. A dummy data addition section corrects the difference between the read rate and the send rate by adding dummy data to the data written in memory. A read clock generation section produces a read clock that matches the read rate, and a dummy data removal section eliminates the dummy data from the data read out from memory based on the read clock.
