Delay Is Killing Me

cmkunisch · 01-11-07, 11:23 AM

I own a restaurant and have a beautiful 46" Sony Bravia LCD right in the middle of our back bar. The hd signal is delayed in comparison to the sd running to the other "older" tvs in the same room. It is causing quite a problem. Watching the fantastic hd lcd isn't much fun when the rest of the room is cheering for a play that hasn't even started on the hd set. Is there a way to delay the signal to the sd tvs or to speed up the signal to the hd? Hopefully I can solve this by Super Bowl Sunday or I am in trouble!!

You can't easily delay the analog TV. You could get a digital set top box receiver and use it to feed the station downconverted to the analog TVs. This should have only a small time offfset with the LCD. John

Take the composite output of an HD STB and feed it into a modulator. This can then feed a video distribution system for your SDTVs. There will then be no delay difference.

Thanks for the replies!! Is this modulator readily available at a Radio Shack or something like that??

first, what is your source for the HD? Cable, Satellite or what? And what, if any, type of external STB (the channel selector part) including the model number do you have. You might not need a modulator.

High def cable box from cable vision on the high def flat panel. IO digital cable on the other standard def tvs. Don't really need the io boxes but got them to at least have all tvs in synch when flat panel is not on a high def staion. Not sure what a STB is.

In other words, we need the model of the High Definition Cable box.

A simple solution might be to pick up a cheap RF modulator like the ones used for the game systems like the old Nintendo. They modulate composite video output onto channel 3 or 4.

Of course most modern TV's will have a composite video input anyway, so you might also be able to use an amplifed splitter box on the composite output of your HD STV, assuming you have one.

Skip the modulator, the cable box already has one! Use the RF output of the box, amplify if necessary, and split to SD TVs. Of course this assumes the SD and HD outputs are both active at the same time!

Rick_R · 01-12-07, 01:05 PM

Of course if the HD STB has a RF out you do not need a modulator. Both of my HD STB do not have RF out (Dish 6000 and 622) but they both have composite out. Modulators are available at Target ahd Wal Mart for $14.99.

Ok, the answer to your question has already been given, but what you really need to do is replace those other SD displays with HD displays.

Problem solved, and the best of both worlds. C'mon, you're going to more than likely make that money back on Super Bowl Sunday.

Also, be sure to advertise that you're showing the game in HD. Put an ad in the local paper on the Friday and Saturday before the game.

Most people are surprised to learn that Super Bowl Sunday is one of the slowest days of the year. Most people go to house parties not to bars.
One of my locations has three hd tvs so we are attempting a Super Bowl Party for the first time in over ten years. Hopefully the sweet flat panels, open bar and nice buffet will draw them in (as well as a chance to win a 32" flat panel at half time). We'll see. Ticket sales have been slow so far.....

Exactly why I was trying to determine which STB he had.

I got it Fan, but we weren't getting anywhere quick!

true that!!! I just didnt want to make the statement that he did not need the modulator for sure (though i hinted it yesterday) without knowing exactly which STB he had.

During the "Titans vs Rams" SB, we had an open buffet at the bar I worked at. It wasn't a typical buffet, we had smoked ribs, crab legs, and the like. Everyone did have to pay for drinks, which is where we really made our money.

It was a total success.

Some STBs won't do both SD and HD outputs simultaneously, but you could use two boxes. I would check to see if the SDTV sets have video and audio inputs (or, even better, S-VHS) and then run the SDTV box's output to them via one of those A-V Distribution Amps like stores use. It would be better quality than a cheap (and probably mono) RF modulator.

If you want to get very elaborate, you'd probably want to do both HD and SD boxes for each of several channels, but use a higher-quality RF modulator for each "game"....that way, every set would match up to what was on the HD sets, and patrons could dial up whatever game they want to watch at their table.
