  [a general note on the High Definition TV debate going
  on in the U.S... there are articles about digital tv and
  commitments made for traditional broadcast stations to
  split up their spectrums to enable a change in tv-tuners,
  which will add to costs of today's television equipment.
  this seems to be the general situation. problems are many,
  and for many sectors in digital & telecommunications sectors.
  with a long-interest in HDTV developments, it seems that a
  serious roadblock/logjam could be occuring, as with other
  industries and technologies and standards and economics.

  not have any answers to the present situation myself, one
  thing has stuck in my mind about how digital television may
  and-or could be slowly integrated into current technology,
  through malleable hardware systems, rather than standalone
  devices that may be obsolete large-investments in contrast.

  instead of a 2,000 large-screen television system, for one
  example, a computer laptop with a hdtv-card possibly could
  modify a computer to function as a digital television. and
  as there are many laptops, this could be one way to bring
  in a very large user base. the second idea is that, like a
  pocket LCD television, a PDA could possibly be designed so
  that it could decode digital television signals, and there
  is another user base.

  economically, this expansion-card/pcmcia-card/compact-flash
  module could enable current systems to find multiple uses,
  to allow a testing platform for various digital tv/broadcast
  services (on a range of devices, not just home theater systems)
  and which could also have infrastructural potentials. as a
  pocket television could be used in emergency services to get
  signals out, especially to those dealing in disaster areas
  who may learn something from the media news, or from intra-
  net datacasts.

  not certain of the complexity of such systems, it would seem
  that a graphics intensive screen and processor would be re-
  quired (most laptops have this, pda's probably not as much)
  and also could potentially function as a type of video-comm-
  unicator, even, if the upstream was text-based, for example,
  over today's existing lower-speed wireless service networks.]
