momentary stop. It is to be expected, however, that agreement will be reached in the coming months and then Europe will finally have its equivalent of the already existing Japanese and American high-technology programs. In the meantime work continues in the non-ESPRIT EEC projects and in national projects in the EEC waitingroom like the British Alvy.
International Ziirich Seminar on Digital Communications The International Zikich Seminar on Digital Communications takes place every two year. In 25 presentations, recent advances in theory and in practical applications within the field of digital communications are presented. The program of the 1984 Seminar is as follows. Session A.

Hanes, British Telecom, Martlesham Heath (United Kingdom). A3 “Performance and implementation of a robust ADPCM algorithm for wideband speech coding with 64 Kbit/s, M. Dietrich, DBP, Darmstadt (Germany). Session B. Image coding Bl “Image coding”, A.N. Netravali, Bell Laboratories, Murray Hill (U.S.A.). B2 “Adaptive transform coding for still picture communication”, H. Lohscheller, (Germany).
