Ryouichi Hoshiai has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Method of transmitting digital video and audio signals between bit rate reduction encoded signal recording and reproducing systems
    Patent number: 5959796
    Abstract: In a digital signal recording and reproducing apparatus, a signal obtained by multiplexing an audio signal on a bit rate reduction encoded video signal is delivered as a transmission signal. The transmission signal is multiplexed with a data showing its content, such as a copy number of times data and an edit number of times data. Depending on the state of reproduction at a reproducing side apparatus, which is a source of transmission, a control data for controlling a recording side apparatus, which is a destination of transmission, is also multiplexed.
    Type: Grant
    Filed: March 13, 1996
    Date of Patent: September 28, 1999
    Assignee: Matsushita Electric Industrial Co., Ltd.
    Inventors: Chiyoko Matsumi, Takahiro Nakamura, Susumu Yamaguchi, Hideki Ohtaka, Ryouichi Hoshiai, Masakazu Nishino
