Digital Cable Resolution #s

1781 Views 2 Replies 3 Participants Last post by  Tulpa
I need numbers:

I cannot fid the answer anywhere.

I know the normal cable carries around 480 lines of resolution.

How many lines will digital carry when its forced onto us, as compared to normal cable? OR will the resolution stay at 480, it will just be digital?

If digital will carry more lines (close to 700) it would make sense to get a 720 LCD TV, then you will get a better picture on it, if it will stay at around 480, then the picture will still look worse than on a non-HD TV.

Please advise.

Non HD channels will be 480 lines of resolution but in digital format.
Yeah, standard def will be 480i, (interlaced, so 240 lines per frame, and the other 240 in the next frame.) That's both digital and analog, and both are available now. The analogs will be phased out over time.

HD will be either 720p or 1080i, depending on the channel. They'll be digital.

As to whether to get an HDTV, it depends on how many HD channels you want, whether your cable company provides enough of them, and whether you find standard def on an HDTV tolerable on the channels that are also provided. We can't really answer those questions for you.
