I need to correct myself -- I just learned from the FCCs website
(http://www.fcc.gov/oet/faqs/dtvfaqs.html) that after next February, at
least some of the digital channels are currently broadcasting on
temporary channels, and will move back to their old location after the
Question: What are the channel assignments for digital television?
Answer: Under the FCC spectrum plan, we have provided most
existing broadcasters with access to a 6 MHz channel for digital
broadcasting within a core digital TV spectrum, i.e., TV
channels 2 to 51. Because of the limited availability of
spectrum and the need to accommodate all existing facilities
with minimal interference among stations, however, during the
transition some broadcasters would be provided DTV channels
outside of this core spectrum (channels 52 to 69). These
broadcasters would have to move their DTV operations to a
channel in the core spectrum when one became available.
Broadcasters whose existing NTSC channels were in the core
spectrum could move their DTV operations to their NTSC channel
at some time in the future. Broadcasters whose DTV transition
channel and existing NTSC channel were both outside of the core
area could obtain a new DTV channel when channels in the core
spectrum are recovered.
After the transition period (2006), the VHF channels (2-13) will
remain available for DTV and the analog TV service will end on
It is true, however, that some parts of the currently allocated
television spectrum will be auctioned and/or reallocated for other
purposes after the analog cutoff (see
So to answer Kevin's original question, no, the Hisense tuners won't be
bricks even then, because they scan all channels from 2-69. That means
that regardless of where the broadcasters end up after all the shuffling
is over, worst case is you'll just have to run the channel scan menu
