Wireless Video

(1/2) > >>

David Sharp:
Our pastor would like to be able to control his power point slide show from the pulpit/stage. We currently use a PC in the sound/video booth with Easy Worship feeding the same video signal (VGA) to 2 ceiling mounted projectors. The pastor uses a MacBook so anything we get must be apple & pc friendly.

He wants to be able to have his macbook on stage controlling the slide show from there. I'm thinking we need something in the booth to switch the signal from his macbook to the easy worship pc (must be VGA input) & we need a device to transmit wireless video from the stage to the switcher (distance 25' approx w/ a few rows of bodies blocking direct line of sight). Make sense?

Any product suggestions?

We use a (now out of production) digital switch. We wish we could afford a scaler with multiple inputs or a HD video mixer.

Another part of the equation is the length of the video cable required from the lectern to the media booth.

David Sharp:
I was hoping to find a wireless solution from the stage to the booth (about 50'). Something you can just plug into the PC/Mac's USB port and transit video to a receiver with a VGA output into a switcher.

I'm really asking for everyone's opinion on:

1. A wireless USB to VGA (15pin) receiver/transmitter
2. A video switcher with 2 VGA (15 pin inputs) and at least 2 15 pin outs.

Does your pastor really need to have complete control of his PC/Mac?  If all he's doing is selecting next slide or previous slide in one Power Point presentation, then the computer can stay in the equipment booth and he can use an RF remote control to advance the slides.

That's a relevant question. We tried to stuff a RF wireless keyboard down our pastor's throat for about a year, and he was never really happy with it.

The good news was that the wireless keyboard worked reliably as far as it went. The band news is that just a keyboard and a mouse provide only a pale shadow of what you get if the computer is right before you.

The wireless mouse/keyboard system really needs to include a copy of the screen that he can clearly see to even be in the ballpark. Othewise, he's flying blind.
