4 video outputs from 1 device

[mezelve]

hi all
i have this a idea for a new sort of device for vj's
it should be something that has 4 outputs of video, so you can connect it to a mixer, so the product should be a sort of a clip library where you assign the clips to one of the 4 outputs (let's say that you do this with a 15" touchscreen)
what should be the advantage of this
this product should be bought by clubs, organisers, companies who rent stuff out, ... so the vj only needs to bring his (firewire) harddisk(s) with his clips, those clips should be arranged in premade libraries with thumbnails

the product just has simple video controls like play, speed, ...
no effects, those you do with the mixer
but maybe if the hardware is up to it, stuff like that can be applyed to it

it could become a new sort of product family, a light version with 2 outputs, highend with effects (heavier hardware), ...

so now i have some questions

1. does it make sense?

2. is it possible to have 4 outputs anyway
is it possible to have like 4 scanconverters
or should it be something like a matrix spliter

3. any thoughts on the hardware side?
is it actually possible to run 4 clips at the same time from one harddisk or should there be more than one

4. is there already something like this, even in the highend range

5. usefull links

6. any input would be appreciated

I have already seen something like this running at an event in England. The visuals company were using a video server that had a 4 channel broadcast quality mpeg2 card. I also know that they were using a Sony scan converter. The scan converter was a digital one capable of converting RGB to PAL/NTSC or back the other way. I am not sure if they were using the scan converter for the signal coming from the video server because they were also using another computer running a VJ program. I can't remember the name of the company who made the video server or mpeg card. I do know that all the clips were running for one hard disk and that they were loaded into memory, then they just looped. All of the feeds were mixed together on a MX50. The price of this set up isn't cheap, the mpeg card cost over ?1500 and the scan converter was over ?3000 but the quality (clarity) of the visuals was superb. I hope this information will be of some help to you. I'm sorry I can't be more specific.
