Video Art Installation/Delayed Playback Help

[mrpie42]

Hi,

As part of my final Fine Art Piece, that'll be exhibiting at my graduate show, im setting up a couple of video installations. (Abstract films, flashing lights, projectors, that sort of thing.)
For one part of it, I want to set up a video camera linked to a tv screen. Whatever the video camera films is then played back on the tv screen with an arbitrary delay of about 10 seconds or so.

i.e. the video camera films a person standing in front of it, as they're watching, their image from 10seconds ago appears on screen, and they watch themselves watching the screen (so not simply a reflection, as they are seeing events that have already happened.)

My question is, How do i go about creating this delayed playback system?

I will have access to computers, an imac, digital video cameras, and standard tv's.

Any ideas on how to set this up?
Thanks in advance!

Broadcasters in need of digital delay to censor (if needed) live telecasts use devices that are likely far beyond your budget. Prime Image makes the cheapest one I know, but even that exceeds $8000 (US).

Digital DVR boxes from cable and satellite providers can certainly "pause" live telecasts and can delay the program stream for as many seconds as you keep it paused. But those are proprietary systems that deal with MPEG-2 or MPEG-4 streams derived from digital tuners. Unless you could input your camcorder video with a compatible codec to such a box at an acceptable bitrate (and I seriously doubt you could -- I'm just offering a vague theory), there is not much that can be done on the cheap.

I'd check out stuff from Enosoft, and then use that with Graphedit and drop in a type of delay tap.

You could probably also do it in AVISynth with a script and plugin.

edit: you didn't say what kind of camera you've got... more info please

Being a poor art student, the budget is fairly non-existent haha.
Also I'm very new to video editing etc, but that AVISynth/scipting idea sounds promising? More info please?

The video camera I've got is Panasonic NV-DS27B Mini DV Digital Camcorder. However, I would be able to borrow other more advanced video cameras from the college, unfortunately I'm not sure what they are.
