The new Carbonite+ 2RU processing engine includes Frame Synchronization and Format Conversion for every input as well as increasing the number of available DVE's from 4 to 8. Just like Carbonite, the + frame is available with 16 or 24 active inputs, with all inputs now simultaneously capable of accepting unreferenced signals and converting SD (625 or 525) to HD 1080i format with aspect ratio choices. Additional DVE's allow every MLE key to have DVE assigned, making it possible to display 8 boxes on screen simultaneously or transition between quad box layouts.
