Not sure if this is the right forum but...

Trying to Skype in a director. Using new iPad and the proper cable from apple. Going into the video port of our switcher which then leads to the video projector.

Sound comes through fine (goes through the mic mixer to CP650), but can't get a picture. I can connect to YouTube and get videos, so a picture does go through the system. Is there something YouTube does that Skype doesn't?

Martin, does your switcher do upscaling as well? If not, you're not gonna get Skype to work as the resolution is wrong (too low) for the projector to handle.

I had a similar situation at a client's house with an AppleTv box. I had to program the AMX to set the projector to a forced lower resolution when the AppleTv box was selected.

Yes, the switcher does upscaling. I'll play around and see what results I get.
Thanks

This was done at Bradford during the Widescreen Weekend in April. Not sure what they went through. Dick should know if he's reading this.

Hmm. I don't understand. First, the iPad has it's normal iOS 'GUI'. Can you see that on the projector? The Skype video windows just appear on that GUI when camera is enabled and a call open. Do you get Skype video working on the iPad screen? Is this only a fullscreen problem?

Unless you need some sort of external video card (like a VGA card, for example) that the switcher would recognize and be compatible with....

...just some guesses..

Ok:
Switcher: Extron 78C
Projector: Sanyo PLC XF40
Composite video connection to switcher in video mode. Component out to projector.

I tried running through the scaling options, so far no success.

When playing videos from YouTube, YouTube on the iPad says the video is playing on the TV. I then see the video projected on the screen, not on the iPad. If I am not playing the video, nothing goes to the screen, though it looks fine on the iPad.

If I play a video embedded on a different website, same thing. Video plays on screen, but nothing else gets to screen when video not playing. If I leave website while video is playing, video freezes on screen and stays there after the jump to new page.

So, no, iOS GUI is not visible on screen when it is on the iPad.

Clearly YouTube sends some sort of signal that activates the "TV". How do I make other programs send the signal?

"Video Out" via the iPad connector is application-dependent. It's not built into the iOS itself. You can't get "Video Out" if the Skype App doesn't support it.

The following is a quote from Apple's knowledge base. The link to the entire page is: iOS: About Apple Digital Video Adapters

quote:
Note: Third-party apps may offer video out or video mirroring. To determine if an app supports either feature, refer to the Info page for the app in the App Store, or contact the developer.
So now we have more questions:

1. Does the Skype iPad App support video out?
2. If so, are you running the latest version of it?
3. Is there some special reason you need to use an iPad for this? Have you considered just using a laptop?

Pretty much what Manny said.

Ironically, the separate "video out" feature is what makes the Ipad a reasonable playback device for some applications: the control part of the interface lives on the Ipad's touch panel, while the actual video part goes out the "TV" (VGA, usually) interface.

Is there a way to send the regular Ipad touch panel output to an external monitor as well? I don't now, but there might be an app that does that.

The whole thing made me think of a thing we once had on a DP100 and protected content on the pc screen.
Might be something like the HDCP protection on video.

1) I'm guessing not
2) Just upgraded both yesterday
3) Because I have an iPad at the theatre, and bought the cable/adaptor. Just ordered some new cable to try and get it to work with my laptop.

I've done this with the laptop a few times and it works fine that way. You'll probably find it a lot easier than trying to do it with the iPad.

Not sure if this is your first time with Skype, or just your first time trying to do it with an iPad -- but, just in case, here are my (I hope) helpful tips and tricks:

Laptop on a podium, using the on-board camera & mic
Plug your laptop into AC power -- don't get caught with a dead or dying battery!
Video out to projector
Audio out to sound system
Microphone nearby so that the question can be heard by the audience
If you have a choice between Ethernet or Wi-Fi, use the Ethernet connection.
Box "taped off" on the ground to demonstrate where people should stand

I set all of this up in advance -- before show time -- and if you're good at "dressing" things, it can be done in such a way as to not be distracting during the screening.

Other tips:

If you've got a lot of friends & family on Skype, consider creating a separate account for Q&A so that your audience doesn't see all your "buddies" coming and going online/offline -- it would also be awkward if you started getting personal incoming calls or messages during your Q&A.

If you do create a separate account, make a note of the user name and password -- especially if you're likely to forget this stuff after not using the account for a few months. (I'm on my second account since I forgot the first one.)

Turn off email programs and anything else that might cause a pop-up to appear on-screen. Consider creating a separate user account just for Skype Q&A so you don't have to worry about personal effects like email popups, or people catching a glimpse of your cluttered desktop (or porn collection?).

Note -- if you're using a Mac, and you have enabled the Guest User feature, you can log in as a guest -- upon logout, it deletes all traces of everything you do in that User Account. Nothing on the desktop, no web browser history. Nothing.

Test the system *in the cinema* by calling a friend (who is not in the cinema).

Sometimes I'm lucky enough to get "test time" with the actual interviewee. They're often eager to test if it's their first time. In that case, be prepared to hold their hand. (If you're on a PC, it may help to know the Mac version of Skype -- and vice-versa.) Testing with the filmmaker also ensures that you have successfully added each other to your Skype contacts.

If you don't test with the filmmaker, make sure that you *have* been added each other's Skype contacts.

Send the interviewee an email with the date and time of the screening and the anticipated time of the Q&A call. State which time zone you are talking about. I usually let them know that I will log-in at show time and then send them text messages (via Skype) to keep them updated (countdown til end of show).

Exchange phone numbers in case you don't see each other online, you can find out what's going on -- is their internet connection acting up? are they stuck in traffic? did they totally forget about the call?

Thanks for the tips. First time Skype and first time iPad. The event isn't until 3 weeks from now, which is why I'm doing the tests way in advance with the filmmaker
When I get the cables for the laptop, I'll report back.

Skypers,
Here is a quick version of what we use. This may not be the easiest way but I think it works out good for both guest and audience.

Things you will need:
-Soundboard next to sound rack with Aux/Monitor out (goes to Mic IN or Line IN on laptop)
-A mic in the auditorium so that your audience and guest can hear
(It can be wireless in booth, send this channel to the
Aux/Mon channel)
-Laptop (in the booth attached to video projector)
-An Igrabber or video capture device that will work as a webcam
-Video camera with s-video or composite out.
-Long s-video or composite cable to reach your camera at the front of the auditorium (you can get these cheap from a online security camera store, and composite is fine since this will only be seen by the guest.)
-Cable from laptop headphone jack to channel on soundboard
-Ethernet cable connection
You may want to record the event with the guests permission.
SuperTinTin is a great fairly cheap automatic skype recorder that records directly from the streams so you can record in different ways, such as side by side if you want.
One more tip, as I think Manny mentioned, you will want to direct the question askers to stand in the camera's view, if the guest cannot see the person asking the question and how they are reacting they may ramble on making their point over and over, as they are not seeing the visual cues that say "Ok, shut up, I get it."
Also, if you use this method you may want to have a google voice account setup so you can call them on their cell phone in the event that the whole skype thing craps out, which it inevitably will. Then you can keep the same setup and just put a nice picture from the interweb up there on the screen, hopefully an embarrassing one from a British tabloid.
Below is the link to the Igrabber
