1. A display system comprising:

  • a plurality of display mediums;

    said display mediums having a display transceiver means for receiving aerially-transmitted digitized signal bit streams and for transmitting aerial signals, display medium memory storage means for storing digital data, a display medium processor means electronically coupled with said transceiver means and said display medium memory storage means, said display medium processor means under control of a display medium data program routine stored in said display medium memory storage means for processing and storing data encoded in said digitized signal bit stream, a display means electronically coupled to said display medium processor means capable of visually displaying a non-preset number of images in response to said aerially-transmitted digitized signal bit stream, and a data recognition means electronically coupled to said display processor means for determining if a received transmission contains one or more data keys which are in accordance with a key protocol stored in said display memory storage means and permitting input of data encoded in said digitized signal bit stream into said display processor means only upon verification that such one or more data keys is in accord with said key protocol;

    a plurality of condition monitor means for monitoring conditions in the vicinity of said condition monitor means and transmitting an aerial signal with respect to said conditions, said condition monitor means having a transceiver means for transmitting and receiving aerial signals, and a detection means electronically coupled to said transceiver means for detecting ambient conditions;

    a central processing means disposed at a remote location from said plurality of mediums having a central processing transceiver means for aerially-transmitting a digitized signal bit stream to, and receiving aerial signals from, said condition monitor means, a central processing memory storage means for storing digital data, a central processing means co-processing means electronically coupled to said transceiver means and said central processing memory storage means, said central processing means co-processing means under control of a central processing data program routine stored in said central processing memory storage means for co-processing said aerial signals from said condition monitor means and effectuating transmission of said digitized signal bit stream in accordance with said central processing data program routine to said display mediums;

    wherein one or more portions of said digital signal bit stream correspond to a command instruction data set interpretable by said display processor means and a data key data set interpretable by said data recognition means, said data key data set portion for unlocking said one or more display medium processor means responsive to said data key data set portion so as to permit reprogramming of said display medium data program routine or broadcast of a message or messages encoded in said digital signal bit stream signal in accordance with said command instruction data set portion of said digitized signal bit stream signal onto said display means of said unlocked display mediums and wherein said data key data set and command instruction data set of said digitized signal bit stream generated by said central processing means is generated in accordance with said central processing data program routine using data transmitted aerially to said central processing means from said plurality of condition monitor means.
