Ass roddymcg says, the crestron NVX platform has been the most predominate HD over IP that I have sold in the last year. With the addition of the DM-XIO-DIR-80, it so simple. Each box is an encoder or decoder and comes in stand alone form or card based for a rack mount frame. Will use some Metra stuff for smaller 1 to 1 applications though.
I may be schizophrenic, but at least I have each other.
