Multimedia tele-education - PC based real-time narrowband applications

After surveying tele-education systems and technology, this study describes the design of a tele-education system which is particularly suitable for the extension of the educational facilities of universities to remote communities. The study is focused on the application of third-world small-scale institutes like the University of the...

Implementation aspects of a decompressor for compressed METEOSAT data on a VME/68000 system

This report describes the results of a feasibility study into some aspects of a proposed METEOSAT image data compression unit. The study was performed to support the preparation of a proposal for ESOC. For the considered algorithms (ESTEC 1 & MEANDER 1) an estimate of the needed processing power based on the 68000 instruction set was made. This...

Data compression in computational fluid dynamics

Computations in numerical fluid dynamics create large sets of data. Transmission of these datasets requires a high speed communication link or, alternatively, the use of data compression techniques. This report describes the results of a study to the applicability of data compression techniques. An algorithm is designed that yields favourable...
