Ok guys... boy do I have some questions for you all... First off i'd like to say I'm a huge Scott Wilkenson fan, so if he's reading this. Hi!!
Now down to brass tacks.. I have a bizarre set up that my parents hooked up and now that I'm getting older, I"m trying to make sense of it. Ok I'm setting up a small home theater for the first time and need some help. I have comcast for TV service. The connection coming in to my house is on a Co-axial cable.
Question 1: We apparently have xfinity service, so does all cable HD or SD come in to your houses by Co-Axial cable? Are all Co-Axial Cable the same? Can co-axial even carry an HD signal?
The connection into my house leads to my first cable box in my basement. The cable box is SD. No HDMI or HD output possible. From there I have another Coaxial cable connected to another cable box upstairs. This upstairs cable box is HD capable. So basically I'm using the signal from my downstairs box to feed a signal to my upstairs box.. If I disconnect the downstairs box, from the upstairs box... the upstairs box looses all picture and sound. So this brings me to
Question 2: What is the point of this? can't we just get a splitter and split the signal coming into the house, giving a side to each box, instead of daisy chaining it?
Question 3: Does the fact that the ISP cable coming into my house, hits a non HD cable box, before being sent to my upstairs cable box, reduce the HD signal that I'm potentially getting from comcast?
I ask this because my upstairs box while, it says it is HD compliant and has multiple HDMI input and outputs, and the component ports, it can not be switched from 480i. (which looks utterly vomit worthy) The tv we have connected to the upstairs HD box is HD as well. But the cable box seems stuck only at 480i, even though 720 and 1080 are available just not selectable..
Question 4. the box I have upstairs, says it is HD compliant, and capable..but the thing is, is the 'cable in'
port, where the tv signal comes in from, is only co-axial. So this leads back to the first question, is the signal from the box outside, always supposed to be co-axial, even if we have a Xfinity, which is supposed to give us an HD signal?
Question 5. Up stairs, I have my cable box (remember this is daisy chained to my cable box downstairs) and I have another co-axial cable connecting it to the TV. Thinking that this was the reason for the cable box being stuck at 480, I switched out that TV-Cable Box coaxial, with an HDMI. The co-axial connecting the two cable boxes though, remained. The upstairs box was still stuck at 480i.
If it is, Something along the way is bringing the HD signal back to SD quality, and it shows..
Now for a bit of terminology confusion. the term cable box and tv receiver are pretty much the same thing?
BTW this is the box that I have : http://media2.comcast.net/anon.comcastonline2/support/help/faqs/settopboxes/DCX3400_User_Guide.pdf
Guys I thank you for sticking around this long! I hope I haven't sent any of you to the hospital, but I'm trying to get this cleared up before I buy any equipment..I eventually want to get a decent set of speakers, and woofer.
