Exchange of the Text |
 |
One of the easiest tools for disinformation is to exchange the words written below a photograph. The entire meaning of the picture can be varied like this:
- The visit of a school-group at a former international camp can change into a camp, where children are imprisoned (which happened in the Russian city of Petroskoy in 1944).
- Victims of war can change nationality. The picture of the brutal German soldier in World War II that was shown in many newspapers to demonstrate the so-called typical face of a murderer, turned out to be French and a victim in other newspapers.
- In 1976 a picture of children in a day-nursery in the GDR is taken: The children, coming out of the shower, were dressed up in terry cloth suits with stripes. The same year the photograph with the happily laughing boys and girls wins the contest "a beautiful picture". Two years later a small part of the photograph can be seen in a Christian magazine in West-Germany, supposedly showing children from a concentration camp in the USSR. The smiling faces now seem to scream. (source: Stiftung Haus der Geschichte der Bundesrepublik Deutschland (ed.): Bilder, die lügen.

Satellites
Communications satellites are relay stations for radio signals and provide reliable and distance-independent high-speed connections even at remote locations without high-bandwidth infrastructure.
On point-to-point transmission, the transmission method originally employed on, satellites face increasing competition from  fiber optic cables, so point-to-multipoint transmission increasingly becomes the ruling satellite technology. Point-to-multipoint transmission enables the quick implementation of private networks consisting of  very small aperture terminals (VSAT). Such networks are independent and make mobile access possible.
In the future, satellites will become stronger, cheaper and their orbits will be lower; their services might become as common as satellite TV is today.
For more information about satellites, see How Satellites Work (http://octopus.gma.org/surfing/satellites) and the Tech Museum's satellite site (http://www.thetech.org/hyper/satellite).
