To be fair, the ATSC standard was conceived largely to replicate the
practices used for legacy analog broadcast systems. The standard does not
support a variety of capabilities that are better handled in an
"intelligent receiver." In the long run, this fact alone may be the
downfall of broadcasting, as significantly enhanced capabilities become
commonplace with new digital media appliances that pull content from the
Internet.
Craig,
You've been on that same theme for over a decade. Ten years ago you were
saying that we needed intelligent receivers that could have their codecs
updated via firmware, that the receiver should be able to add graphics and
station bugs, and the receivers should be able to cache micro-targeted ads
for insertion at the STB.
However, broadcasting is a mass medium, and you cannot just go around
killing people's receivers just because it no longer supported the most
current "update." The receivers need to be as simple as possible, and the
broadcast stream has to at least remain backwards compatible with the very
first Zenith Blue Rack.
Whatever "intelligent receiver" that would have been designed in 1999 would
be woefully obsolete today, and broadcasters can't afford to alienate
viewers by making their old receivers go dark simply because those old
receivers no longer have the graphics horsepower or cache memory required to
run the latest version of the "ATSC OS."
