HDMI Splitter 1.3

Anyone have any experience with these? Anything with the word "booster" in it makes me think of those shitty old Radio Shack rabbit ears that plugged into the wall and subsequently did nothing. :lol:

The one I'm looking at is the 2 in, 2 out.

I don't really see anything wrong there. If it has a "booster" circuit of some type I would guess it's to stave off attenuation over longer cable runs?

Except it's digital... there is no attenuation.

Explain maximum cable length in USB spec The information is digital, the signal is still electrical over a wire, if that signal gets too weak, it doesn't decode properly.

false, the electrical signal can still go down. up to a point, it wont do anything, then when it hits that point MASSIVE EXPLOSIVE ARTIFACTS OF BADNESS will happen. this will just prevent that from happening over longer runs most likely

I use the Rocketfish 4x1 in my office and I love it. I have two of them, one on each lower monitor, so that I can toggle between Uverse, PS3, and PC output on any monitor - all via remote control.

One of my newer monitors also splits into 6 zones so I can have, at bare minimum, PC plus several different Uverse channels on at one, all on one monitor.

My company uses these for trade shows, and they work great:

StarTech.com 2 Port HDMI Video Splitter and Signal Amplifier and other Audio/Video Switch Boxes at CDW.com

I thought it had to do with polling intervals since data is sent serially, but a quick Wikipedia check seems to support your thesis.

Ahh well, I was generally operating under the assumption that HDMI runs weren't stupidly long. Of course, that can change in many corporate/conference-style setups.

Guys, thanks for pwning Josh :lol:

Attenuation is always an issue with signalling. Even with fiber optic technology the light dissipates at some rate.

This man speaks the truth.

if it didnt, an infinitely small cable could carry infinite bandwidth :agreed:

:lol:

That is clever as fuck :lol:

Holy shit I'm litterally laughing out loud.

 

[Josh]

:rofl:

I know attenuation happens, I just wasn't aware that it would seriously affect digital signals on standard consumer-sized cable runs.

It depends...if you are trying to get HDMI video from one end of your house to the other attenuation is likely to be an issue. Store bought cables will not have any attenuation issues because they are usually well within the standards.

Doesn't the bandwidth issue have more to do with crosstalk than just attenuation? I suspect they are related anyways.

 

[Max]

an ideal unattenuated digital signal in perfect condition is capable of a 100% lack of crosstalk. Thats an ideal situation clearly, and not a real world viability, but the thought is nice :lol:

Ah yes, that's what I was thinking.
