We are looking for related words/terms and/or acronyms that can be added. If you know of any, please post them here in this thread and we will review the suggestions for addition to the glossary.

CRT – you might add that this is the screen (display?) that TVs and personal computers have used since their conception (until recently). Basically consists of three “guns”, red, green and blue. Brucek can probably give you a better technical description of them, but it needs to be brief and concise for this.

By the way, how does Dynamic Range Control add up to Dolby Digital?

Regards,
Wayne

ghz – needs to be gHz

Added CRT definition:
Cathode Ray Tube - A vacuum tube in which a hot cathode emits a beam of electrons that pass through a high voltage anode and are focused or deflected before hitting a phosphorescent screen. The original screens/displays used for computer monitors and televisions consistig of a red, green, and blue color lense.

Corrected GHz, added Hz and KHz (already had MHz).

I'm not familiar with DRC... maybe Naut can elaborate.

SWMBO She who must be obeyed. Always makes me laugh.

**Sonnie** · **09-17-06, 01:01 AM**

few more:

spl, sound pressure level

sxrd, the sony display thing.

LD laserdisc, a mystic device of an av time long gone.

RF Demodulator, some kind of voodoo box asociated with laser discs and DD, and non av types to connect dvd players to old tvs.

Gamma see http://en.wikipedia.org/wiki/Video_gamma

Id also add that rca is a kind of connector usualy for sound and component video.

**lcaillo** · **09-17-06, 01:41 PM**

That would be RF Modulator, not Demodulator. Your tuner is a RF demodulator.

I've added quite a few and changed it up a little... still have a few more to add, but you can check it out.

If you believe we can improve on the definitions, please advise here and we will make the necessary changes.

**Sonnie** · **09-17-06, 10:42 PM**

I couldn't find any definition for VC-1 and AVC. If someone can get me up a definition, I'll add them. I don't even know what they are an acronym for.

I think all the rest are there.

From the horse's mouth, or other end, depending on your computing orientation:
http://www.microsoft.com/windows/win...2005/VC-1.aspx

AVC could be Automatic Volume Control or a video compression algorithm:

**lcaillo** · **09-18-06, 03:22 AM**

Also add Skew, Pincushion distortion, G2 Level (Screen Level)

Note that Balanced audio connections can also use 1/4" Phone jacks and plugs not just XLR.

**lcaillo** · **09-18-06, 03:23 AM**

And one of current interest - CEDIA

**eddthompson** · **09-18-06, 04:15 AM**

AVC i was refering to the video compression, i believe sony were going to use it on bluray instead of vc1, i think both are derived from mpeg4.

How about some layman's definitions relating to subwoofer tech terms like:
Xmax, Bl, Vas, Fs, F3, etc...might want to make them some kind of sub-category under subwoofers, IB's, etc...

**Sonnie** · **09-22-06, 02:30 PM**

Thanks edd!

Yes John... that is a great idea on the TS Parameters... which is probably where they should be sub-categoried at.
