    It has been shown that interframe coding techniques provide an effective means to reduce the transmission bit rate of video signals without sacrificing picture quality. The channel capacity of various coding schemes over existing digital transmission links is listed. For digital satellite, for example, even a single television (TV) channel cannot be transmitted by conventional PCM, whereas one or two channels of TV can be transmitted by employing efficient coding techniques. However, much greater advantage is obtained by use of interframe coding. Three network quality TV signals can becarried through a transponder. For teleconferencing applications, a single satellite transponder can managuep to 20 simultaneous conference signals on a TDMA basis, if one uses a 3M bit/s interframe coder. Our satellite experiment has demonstrated excellent performance for network digital TV application. The TRIDEC teleconferencing system has been commercially used by NTT in Japan since 1979 and the NETEC-6/3 interframe encoder is being seriously considered for application in North American teleconferencing applications.

    It is artgued that the trends of developments in communications systems directly concern a nation??s present situation and future vision, and its services and impacts should be perceived as a major national issue. It is, therefore, necessary for each nation to make the most suitable choice of communications systems based on its specific environment and objectives. View full abstract»

  • Is science and engineering training adequate?

    US President Carter "increasingly concerned," directs NSF and the Department of Education to report on this question by July 1 1980. The study has been ordered partly because American industry is faced with a shortage of engineers, especially engineers trained in computer-augmented design and manufacturing techniques. Also, with most new engineering graduates finding attractive jobs in industry upon receiving their bachelor??s degree the engineering schools are discovering that to recruit enough graduate students and ju nior faculty they must look increasingly to foreign-born nationals.

    In the labyrinth known as the United States Government, it is often difficult to identify exactly who creates and executes policy. At the Pentagon, Gerald Dinneen, Assistant Secretary of Defense, among other responsibilities, oversees the US military??s communications network. In a recent interview he discussed his myriad tasks, special problems, and the differences between a job on the firing line as a presidential appointee and a research position. Before joining the Carter administration, Dr. Dinneen was Director of M.l.T.??s Lincoln Laboratory. View full abstract»
