"experts" believe that broadcast television (TV) is effectively dead,
but in the last couple years there has been work done to re-invent over-the-air
transmission in what spectrum has not yet been yielded to White Space
for other uses. One of the major hurdles to overcome is how to service
mobile devices that, if the effort is to succeed, must be able to work
acceptably in the presence of a constantly moving receiver and the multipath
phenomenon. Of course HDTV (high definition) will be expected by viewers
so that adds to the difficulty. There are some grand plans for interactivity
and on-demand programming that is not even available today to traditional
household TV viewers.
There are many new services vying to operate
in the newly available White Spaces, including new cell bands, security,
surveillance, and other such things. Ever ready and willing to provide
the electronics, hardware, firmware, and software to enable an army
of inventors and investors, White Space, HDTV, and re-purposed broadcast
television vendors are scrambling to be first to market. Some of those
companies are listed here.
