Originally posted by miatasm Hit the Nail on the Head, Patrick. It is possible to do what you ask but it would require a lot more bandwidth to become available. We would have to send channels 1-99 out twice. One in analog & again compressed and modulated in digital. |
It would take up waaaaay too much unnecassary bandwith. |
Originally posted by UncD2000 Also, the analog cable channels, typically 2-99, when tuned by the TVs built-in tuner, will have noticeably better PQ than the digital channels |
The analog channels enjoy full 6 MHz bandwidth. The digital channels will have up to 12 channels squeezed into each 6 MHz slot. |
"Digital cable" never had anything to do with quality. It's all about quantity - how many extra-cost channels can be compressed into the minimal available bandwidth. |
Originally posted by Davenlr If cable was all digital, with 1000 MHz of bandwidth to use, Ill bet they could blow satellite PQ away with room to spare. |
Originally posted by UncD2000 The "digital cable" I referred to above is not the HDTV-capable 256QAM |

rbaldwin, if you will check John Mason's post on this thread:
http://www.avsforum.com/avs-vb/showt...hreadid=199900
you will see that his TWC 860 MHz system is doing exactly what you asked about (and I estimated that his system still has room for high speed internet & local phone service, plus at least 34 HDTV channels).
