Abstract
Digital data is provided with a time stamp of an internal time signal of an internal clock. The internal time signal is validated by receiving and evaluating an internal broadcast or a cable signal of an external time source, from which a standard time can be derived, comparing the standard time with the internal time signal of the internal clock, and time stamping the digital data. The digital data is time stamped only if a time difference between the internal and external time signals lies within a given tolerance range. Finally, the time-stamped digital data is encrypted.
