Abstract: Radio transceivers 5 in a communication system periodically broadcast signal pulses 6 to enable a radio transceiver 5 to determine their proximity. Each radio transceiver 5 has a clock 16 for maintaining a time synchronised by a synchronisation means 17 via the Global Positioning System (GPS). Each radio transceiver 5 transmits a signal pulse 6 at the same point in the synchronised time. A signal detector 19 detects the start of a signal pulse 6 received from the closest radio transceiver 5 and a proximity estimator 20 estimates the proximity of the closest radio transceiver 5 by determining the difference between the point in the synchronised time at which the signal pulses 6 are broadcast and the point in the synchronised time at which the start of a signal pulse 6 received from another radio transceiver 5 is detected.

Abstract: The invention relates to embedding in, as well as to extracting a payload from a motion image signal. Furthermore, the invention relates to a motion image signal. A payload is embedded in the motion image signal by the following steps. A first and an at least second watermark are represented by at least a first sequence of watermark samples, and a first and at least a second global property of an image of the signal are determined. Subsequently, the first and the at least second watermark are embedded in the signal, so that a shift of the at least second watermark with respect to the first watermark represents the payload. The first and the at least second watermarks are embedded by modifying the first and the at least second global property in the image in accordance with the corresponding watermark samples. The first and second global properties may be the mean luminance and the mean color saturation of the pixels constituting the image.
