Off brand use for DVR: feasible?

[threeyed 0]

Hi, I'd like to know if this seems feasible.

 

I'd like to shoot videos of groups of people (like commissions, courtrooms etc) of people talking.

 

Using a DVR seems like a sensible way to do this as they are made to record multiple synchronized views.

 

To present these, I'd like to construct web-pages that can show 1, 2, 3, 4 (etc) views of people talking, listening, then shift between these pages to vary the views.

 

So my questions are (if you'll forgive my newbie-ism):

 

1) Do most DVRs generate an independant time-code that can be programatically accessed (required to recreate the views)

 

2) If so, is this code accessible from both the live preview and recorded file?

 

If there are any other hints/tips around this subject, I'd love to hear them. Thanks for sharing,
