HDTV connection help cable and OTA
« on: October 06, 2008, 02:22:36 PM »
I just got a new HDTV.  I have my cable hooked up to one of the HDMI ports.  I also have an antenna on my house, and would like to see what is available OTA.  What would happen if I plugged my antenna into the coxial port on the TV.

Can the cable and OTA play nice together.

Thanks

Sure.  Your TV is capable of multiple sources isn't it?

It does have the digital tuner......I have a bunch of inputs, but not certain the the coxial is one of them.  I have the HDMI, component, and PC.  That is why I'm not sure about the coxial.  Now if I used a coxial to HDMI, (if they are made), then I wouldn't think it's an issue.

We just lost our local FOX affiliate (squabble over money), so I have rabbit ears hooked into the antenna out of my plasma to get that station.  In my area, I get about 16 OTA high-def digital channels, including the one I lost on cable.  All you do is switch the input on the TV from HDMI cable to antenna to go back and forth.

at least in my experience, the OTA signals are a much better picture than the satellite or cable picture....

always will too, because the big companies have to compress before they broadcast.

A quick search on Google show that people tend to agree with you on that....

I was speaking about a 1080i signal on a local channel via DTV and the same 1080i channel through OTA...the OTA signal was better, though they both were in 1080i resolution

The resolution has nothing to do with the compression.  Cable and satellite companies sacrifice bit rate to allow for more channels on their available bandwidth. 

Under normal circumstances compression can be made to be pretty much unnoticeable, but the cable/satellite companies have to do it on the fly so their picture quality does suffer for it.
