In digital there is a signal threshold below which dropout (pixelation) occurs. When an analogue signal degrades the picture just gets 'snowy'. However, digital reception which is running alongside analogue is at quite a low level to prevent interference with the analogue channels and appears more susceptible to weather interference. When the analogue signals are turned off the digital signal is boosted to give maximum coverage and will deliver a better service all round.

If you have a digital tv and an outdoor antennae do you need a converter box?

In the US the answer is probably not. Digital and analog TV broadcasts use the same frequencies and antennas. Digital TV is more fussy about signal quality than the older analog signals. So if you get marginal analog reception, figure on getting a new antenna for digital. The idea that there are special HDTV antennas is just marketing hype. Any antenna that gives you better digtial reception will also give you better digital reception.

Are broadcast digital TV signals affected by weather conditions?

Hello - from all my research it is clear that even digital signals can be degraded by weather conditions. Contrary to statements that claim 'you either get a digital signal or not', you can receive digital signals that have been weakened by weather conditions. I live in Ohio, and am fortunate to be able to use a plain 'bowtie' indoor antenna (no amplifier either) with my TV, and generally get excellent reception. However, when the weather includes heavy rain and especially high winds, my digital reception can randomly blank out, or the picture freezes, or shows random frozen pixels, or loses audio. Considering the high cost and very poor customer service of my local cable provider, I am more than happy to put up with my free, if occasionally less than perfect, digital reception. If you online search "weather conditions and digital TV reception", you can read supporting information. Cheers.

Will the Quasar television model SP3233 accept the digital signal that begins in 2009?

Actual televisions won't be affected by the digital signal change. What matters is what reception tool is used (e.g. cable, satellite, antennae). Television antennae will not work when all television is transmitted using digital signal. If you have cable or satellite though, you have nothing to worry about.
