Hi, new here.
Friend of Curt's, although he would never admit it

Satellite and cable deliver HD channels between 8 -12mbps, OTA(local antenna) does 19mbps.

Blu-ray does 24-40mbps, mostly 24mbps

So it would seem to me the bottle neck on quality would be the source.

A discussion came up as to the best way to distribute HD, through out a building.

I like the idea of clear QAM modulators, up to 28mbps for standard or 38mbps for more expensive units; single video/audio channel per QAM.
You can run 125+ separate QAMs on 1 coax cable.
Use the TV's digital tuner to select source channel
You can also have SD analog channels running at the same time.
Simple splitters for distribution paths.

Direct run Fiber optic was the other method discussed, I like fiber if longer distances are involved(1,000+ft) but find it costly in interfacing and multi-use applications.
Similar to direct run HD-SDI on coax.


So what would be the thoughts on taking a 24mbps Blu-ray HDMI output convert it to 24mbps QAM and sending it out to TV via coax cable and have TV's tuner as decoder
Or taking a 24mbps Blu-ray HDMI output and sending it via fiber to TV's HDMI input.

Would there be a noticeable difference in quality?
Lets say a 65"-70" TV to be practical, not a 32"


I say there wouldn't be, the limiting factor is the source end, as long as distribution doesn't make it worse what you see is what you got from "the box"(source).
