Some "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.
