an integrated service Digital Network isdn based international telecommunication between samsung medical center and hokkaido university using telecommunication helped radiotherapy planning and information system therapis
Radiotherapy and Oncology, 2000Co-Authors: Hiroki Shirato, Seiko Hashimoto, Shinichi Shimizu, Dongrak Choi, Kazuo Miyasaka, Joji MizunoAbstract:Abstract This study introduces the integrated service Digital Network (ISDN)-based international teleradiotherapy system (THERAPIS) in radiation oncology between hospitals in Seoul, South Korea and in Sapporo, Japan. THERAPIS has the following functions: (1) exchange of patient's image data, (2) real-time teleconference, and (3) communication of the treatment planning, dose calculation and distribution, and of portal verification images between the remote hospitals. Our preliminary results of applications on eight patients demonstrated that the international telecommunication using THERAPIS was clinically useful and satisfactory with sufficient bandwidth for the transfer of patient data for clinical use in radiation oncology.

The Evolving Switched Digital Network
Digital Telephony and Network Integration, 1995Co-Authors: Bernhard E. Keiser, Eugene StrangeAbstract:The North American public switched telephone Network (PSTN) has been evolving from a fully analog Network toward one that is expected to approach a fully Digital Network.

The Integrated Services Digital Network (ISDN)
Digital Telephony and Network Integration, 1995Co-Authors: Bernhard E. Keiser, Eugene StrangeAbstract:In 1972, the plenary assembly of the International Telegraph and Telephone Consultative Committee (CCITT) approved Recommendation G.711 for Pulse Code Modulation (PCM) of Voice Frequencies. This provided for a sampling rate of 8000 per second and 8-bit encoding/decoding with either A-law or μ-law companding (see Chapter 3). In 1980, the plenary assembly approved Recommendation G.705 which recognized that substantial agreement had been reached in studies of integrated Digital Networks (IDN) for telephony and that studies leading to an Integrated Services Digital Network (ISDN) were needed. Some conceptual principles to guide the studies provided for: the ISDN to be based upon and evolve from the telephony IDN by adding functions and features; a layered functional set of protocols; gradual transition over one or two decades; new services to be compatible with the 64-kb/s switched Digital connections of the IDN; and arrangements during transition for the interworking of services on the ISDNs and services on other Networks.

an mpeg2 4 dual codec with sharing motion estimation
International Conference on Consumer Electronics, 2005Co-Authors: Yusuke Yatabe, Masahiro Fujimoto, Keitaro Sodeyama, Hironori KomiAbstract:An MPEG2/4 dual codec algorithm has been developed, targeting consumer products with Digital video storage, Digital Network communication, and so on. By using new method of sharing the motion estimation (ME) between MPEG2 and MPEG4, a low power and high quality MPEG2/4 dual codec system can be achieved.
