Abstract (en)
[origin: DE19844403C1] According to the invention, the television images transmitted by a television signal are subsampled in the horizontal and vertical image direction, in accordance with a broadcast-type indicator which is transmitted together with the television signal. As a result the resolution of the television images is reduced to the point where image details can no longer be recognized. The above method is suitable for use in television sets, for example to render the contents of television images unsuitable for children less recognizable.
