Abstract
A technique for on-demand power wake up for digital signage includes providinga detector operable to detect an envelope of a digital signal, receivingan extended length packet by the detector, wherein the packet consists of a same, repeated data symbol, detectingthe extended length packet in the detector to provide an output signal, comparingthe output signal against a reference threshold, and providinga wake up signal if the output signal exceeds the reference threshold. This can then be followed by receivinginformation to display on the sign.
