Y/C to Composite Circuit Diagrams ?
|
Can't Post

|
I'm trying to find a circuit diagram to convert four Y/C signals to four separate (2xY/C - 2xBNC (Composite) - & 2xRC(Composite)) outputs.
So (to explain a little more) - I need to feed four camera's (Sony DSR250P) into a video mixing desk & also provide outputs to a bank of monitors for each camera preview.
I realise DA's would be the way to go, but finances don't allow for this kind of outlay, I'm quite used to building my own equipment, and would be happy to build my own unit if I can find the circuit info.
I know Kramer have a single unit ( Kramer 401C ) which "almost" does the trick (Y/C to 2 x Y/C & 2 x BNC), but I'd like the versatility to be able to use "any" Composite or Y/C output from a Y/C input.
Also, anyone know what the MAXIMUM length of cable I could use from these camera's (Y/C) is - before suffering serious signal loss.
I'd prefer to use IEEE1394 but unfortunately the video mixer we're using is a low cost unit (read "cheap") and only has the facility to I/P two Digital signals. Also I believe that the maximum length of IEEE1394 is around 125 feet, someone may be able to correct me there too ??
Any help/links you may be able to provide would be MOST helpful, as we're trying to put together a small OB unit for local projects here in New Zealand.
Thanx,
Steve Green
