Forum members are clearly interested in the SDI digital output for DVD players. What is the input for the signal. The plasma forum wants DVI inputs for digital input to plasma displays, but it appears that DVI outputs only appear in HTPC video cards. Sorry to sound like such a newb but I am trying to put together a 'state of the art' setup but don't understand the "connections". Do you need a video processor to match the SDI DVD output to the DVI input of the plasma?


Thanks

Carl

Both of these are digital transimissions, but they differ in that SDI is an interlaced signal currnetly, and DVI is progressive. To have a full digital signal path, you would need a DVD player with SDI out, fed into a scaler with SDI in, then DVI from the scaler out to a DVI on a projector in. SDI and DVI have different purposes.


Thanks!

It's their upgrade of the AV32r, which as an option has a built in scaler, that is, it's not only a DVI pass through. More info can be found here: AV192R

SDI was designed to help broadcasters move an interlaced signal from one place to another (distance being the operative requirement here) without any noise added on.


DVI was designed to let a computer be hooked up to a flat panel display. It was designed for very short distances, and to require minimal electronics on the flat panel side. The data is run without compression and in such a way as to allow the flat panel to display the data with almost no electronics on its end of the DVI connector.


So, to sum it up:

1. Devices will tend to output SDI.


2. Display devices will tend to want to use DVI.


3. We'll have to use Scalers and computers as middleware until (if ever) a common video communication signal is employed (Firewire 2?)
