for the past few days i've been thinking about this mandatory switch to digital television
i found this on the dtv.gov site:
Quote:Congress mandated that February 17, 2009 would be the last day for full-power television stations to broadcast in analog. Broadcast stations in all U.S. markets are currently broadcasting in both analog and digital. After February 17, 2009, full-power television stations will broadcast in digital only.
Quote:An important benefit of the switch to all-digital broadcasting is that it will free up parts of the valuable broadcast spectrum for public safety communications (such as police, fire departments, and rescue squads). Also, some of the spectrum will be auctioned to companies that will be able to provide consumers with more advanced wireless services (such as wireless broadband).
Consumers also benefit because digital broadcasting allows stations to offer improved picture and sound quality, and digital is much more efficient than analog. For example, rather than being limited to providing one analog program, a broadcaster is able to offer a super sharp high definition (HD) digital program or multiple standard definition (SD) digital programs simultaneously through a process called multicasting. Multicasting allows broadcast stations to offer several channels of digital programming at the same time, using the same amount of spectrum required for one analog program. So, for example, while a station broadcasting in analog on channel 7 is only able to offer viewers one program, a station broadcasting in digital on channel 7 can offer viewers one digital program on channel 7-1, a second digital program on channel 7-2, a third digital program on channel 7-3, and so on. This means more programming choices for viewers.
i've been wondering about why congress would be worried about my television viewing experience enough to mandate a change
in one of my quotes it says this
"free up parts of the valuable broadcast spectrum for public safety communications"
i'm wondering if there is more to it than what they are saying
do any of you have any thoughts on this subject?
