What cables do professional video companies use?
I know a lot about consumer cables, component, dvi, vga, composite... but what do the professionals use. I have heard a little about bnc and rgbhv but I don't know anything about them or why they are better than consumer cables. Thank you
The items you referred to, "component, dvi, vga, composite" are specific to the connectors - not necessarily the actual cable between the connectors. Same with "bnc and rgbhv".
They will use anything they need to in order to provide a good, solid, connection between compatible devices. There is no "rule" but for the most part, any cable run will use shielded cable. When a professional crew is at work, they want to be sure they get it right the first time so they don't have to go back, take extra time to identify a problem and and fix it - or re-install it. If they are doing a live network broadcast, it is possible that millions of dollars - advertising dollars - are at stake, so a single connector that fails could cost a LOT. If they are on a movie set, the hourly cost can easily hit tens of thousands of dollars. Good, heavy duty, well made cables and solid connections for the connectors may seem expensive up front - but over time it is a lot cheaper to do it right the first time than have to go back a do it again because some cheap cable fell off or broke and something did not get recorded.
Many consumer cables (especially the lower-end cables) are not shielded - and are not typically long runs, either. As short runs, they have less of a tendency to pick up radio frequency or electromagnetic interference (RFI/EMI). RCA jacks can slide/fall off... Compare this to a BNC connector which twist/locks on... They perform the same function, but have a MUCH smaller chance of accidentally disconnecting or otherwise failing. And if a consumer cable accidentally falls off, fails or whatever, this typically does not impact thousands or millions of lost $$$.

How do I convert BNC to line-in?
I'm working on a little experiment, and I'd like to convert a BNC signal from my equipment to line-in so I can record it on my computer. If I can get BNC to USB and then some software so I can record it as an audio signal that would work too. But I have no idea how to or where to get the equipment to do such...
So BNC to line-in audio... is it possible and how?
This can easily be done. All you need to do is go to your local electronics store (like Radio Shack) and buy a converter plug that has BNC on one end and a 1/4" line-out hole on the other end. 1/4" looks like the little hole that you plug your little headphones to (like on a portable music player).
Once you have that plug, then you can simply connect your BNC device into the line-in hole of your soundcard by using a wire that has a 1/4 plug on both ends (buy it from the same store). Then open your favorite music program and choose to record via line-in.
To be honest, I don't know if a BNC to 1/4 plug actually exists...they might tell you that they only have a BNC to RCA plug. If that's the case - buy the plug, but get a wire that has RCA on one end and a 1/4 plug on the other (I know that exists).
If you are confused, just tell the store clerk at the electronics store what you want to do and he should know what you need.
