Multiple videos playing simulateously on a parcel?

Let's say I have an information center on a parcel of land. There are 3 floors, and on each floor there is a media player. On each of the media players there will be a different video presentation. When somebody is watching the informational video on floor #1, somebody on floor #2 could be watching a different video.

Is that possible on a single parcel of land? Are there media players available that do not use the parcel media URL, that stream directly to the video display, audio and video.

A neighbor of mine is planning to do that sort of information/conference center. Personally, I'd be more inclined to have a single video and then the other screens would be presentation/instructional screens (text/graphics - no audio). But the idea has peaked my interest.

Thanks in advance for your consideration.

On any parcel can only be 1 stream. what you can do is devide the parcel up in smaller parcels, all set to same owner/group, and then making sure your media machines are not straight above each other, and therefor not on the same parcel.

It won't have any affect on your building rights this way

I thought about that, that seeming to be the best way; but I was curious to know if there were some scripting/tech innovations outside of my experience on SL. Things do evolve so quickly sometimes here... and sometimes not.

Thanks for the A to my Q, Benski.

Does this information help?

As others have stated, you can't play two different streams at the same time on a single parcel. But you can fake it, if you've got total control over the source material. Simply render a single split-screen video, that has all your smaller videos on it. For example, you could put Video A on the left half of the canvas, and Video B on the right half. Then use the in-world texture offset controls to display one half of the image on each screen. End result, you've got what appears to be two different videos playing simultaneously.

There are some very obvious downsides, though. The first is it's a lot of work to set up. You need a good video editing/compositing program, to render the two videos into one, and you'd need to give some thought to how best logistically to handle simultaneous clips of differing lengths. The second is the audio will be a total mess, since streamed media is not spatialized. If both videos have audio in them, then everyone in the parcel will hear both tracks at a fixed relative volume, regardless of which screen they're looking at. There'd be no way to mute the audio from Video A while you're looking at Video B, and vice versa. And unless your name happens to be Mozart or Data, it can be pretty difficult to listen to two or more disparate audio tracks at the same time.

It is supposedly possible to stream different videos to different people at one time on one parcel.

See http://robsmart.co.uk/tag/streaming/ for one description of this.

Yep. It's definitely possible.

When you use the "Agent" instead of just "Parcel Media Command" it will set that stream for just the "Agent" - the person. So you have a box that plays "video1.mov" and one that plays "video2.mov" - Bob clicks box one and it will start video1. Sally clicks box 2 and it will play video2.mov - on the same screen even.

If you aren't a scripter, I know that the NHC Video system (available on Xstreet - it's almost always on the front page) system can handle this. You put out one tuner (needs to be on the same sim - but it doesn't even need to be on the same parcel for the way we are going to set it up). Deed it to the group if needed and then...

Rez one of the TV's. (The HUD version is the fewest prims - and it will scale up and work just like the others, I think).

First go into the settings and set it to "Private" (This doesn't really mean "Private" in the way we think - it means that each stream will go privately to one person).

Set access to "Owner" (because you are going to want to make it so you set a specific stream for each screen and don't want other people to get the menu.)

Click the "Touch-n-Go" button. (I don't think that name is exactly right - it's something like that though.. basically what it does is make it so if people don't have access to the menu, it will just start whatever video is set for it).

Set the TV to your Help Video stream that you want to show. And then have someone come by and test it. They should click it and they should get the stream you set.

Repeat for each stream you want to show - one screen per stream.

If you want to get fancy and understand the basics of scripting, you can do this yourself too - looking at my link above and the llParcelMediaCommandList function. You can have one "screen" (just a prim with your media texture) and a set of buttons - each one hard coded to the video you want. It's really just one line of code on the "touch" event.

Hope that helps!

This is actually quite simple to script, if you know how you want to associate specific viewers to specific streams (e.g., by proximity to a particular prim, perhaps). It *only* works with parcel media (the subject here), not with audio, but it works well.

As it happens, I'm using it with web content in an exhibit at SL6B to show viewer-specific language translations, so the same prim will show a different language for different viewers at the same time (at about a dozen stations, too, all on the same parcel).

What Chosen describes above addresses a slightly different twist on this: any one *viewer* can see only one media source at a time. So if it's required that a single viewer be able to see several videos playing at the same time, it has to be done by multiplexing the video sources and demuxing them onto screens that each show only part of the parcel media texture. One commercial product that does this is SLipod.

One of the bigscreen @Home Entertainment porno TV's does this. I'd bet some of the lesser TV's also have this "group land friendly" option as well.
