I see ... looks like a provision for IP/commercial purpose included in standard SW of 311 and 222 receivers and not require any special things.

HD digital modulation for sport bars?

any know of some good hardware for this that is not very high cost?

Is it best to fit it into a old SD / analog / coax system that is in place.

replacing the old SD / analog system with digital QAM seems to cheaper then installing a switcher system and running lots of new cable to each tv.

HD tv's are in place.


Good questions, all, and like a lot of things, the answer is 'it depends'.

If you are going to have -all- NFL Sunday Ticket games, then you have to build for 13 games/sources, which is the most I've ever seen in the last 5 years. Add another couple of sources (DVD, ?) so you're looking at 16x Matrix Switchers. I've used an FSR 16x16 Component Switcher w/ 15 displays and it worked great, but the cabling/termination is a large task (BNC). And no matter what you choose for distribution (HDMI to Cat6?), the cabling -can- be a big pita (night work, difficult runs, etc.).

One of the things I like about the ZeeVee 170 is that you can incrementally add them to most existing SD systems if the displays are fairly new and will scan both analog and QAM cable channels and this makes it attractive to the people who are paying for it . Their output (25dBmv) is lower than most NTSC modulators, but most new displays seem to have good tuners and can deal with less than ideal (-10 to+10 dBmv) input sigs.
I just tested a DEMO ZV-170 (ZeeVee has a free loaner program going) by setting the output to 5 dBmv (easy to do from the front panel switches/display) and padding the output with 27 dB worth of attenuators, and I still had picture (-22 dBmv) although I did see it break up a couple of times during the 15 minutes I watched it.
I had to use fans/plenum on the old CableTronix mini agile modulators, but the ZV runs cool as well.

There's a -lot- of misinformation in this thread regarding Component outputs, Inspection? :rolleyes: HDCP (the DirecTV HD receivers have 16 HDCP keys by the way), encryption, etc., most of which doesn't even apply to the programming content at SportsBars, so I suggest you read 'Audio Authority's' take on it at:

I see about half and half in the bars here. Half have receivers on the tvs, other half are using hmdi over ethernet.

They make a great RF remote as well for a whole system solution. Cant remember the name but had a 4"x4" lcd screen and the bartender could control all 25 tvs from it using RF with a rack system back in the back room. All the tvs were numbered and corresponded to numbers on the lcd display. Seemed pretty simple and even the blonde waitresses figured out how to use it!


I'd be interested in hearing the name of that remote if you can get it. I've searched and everything I come up with is many years old.
Simple enough for a blonde waitress is the key!:lol:
Thanks,

Hopw many TV"S?

In how many places do you need to be able to change the channels for all the TVS from?

I'd say go with a Box at each tv, wireless game adapter at each tv with one main router for network control (doesn't need to really be hooked up to anything other than the boxes once its set up, it can be and probably should be on its own network encryption) for control, and an ipad at the bar or wherever you want to be able to control all the tv's.. .

Has anyone made an iPad application for this purpose? And no, the DirecTV one doesn't count because it won't work with commercial accounts.

We make a very nice HDTV Sports Bar system using refurbished equipment.

I assure you will not beat the price for 32 TV's
