The next closest competitor to the IScan HD would seem to be the CS-1 and CS-2. The CS-1 has DVI input and output, but no HDCP. The CS-2 has HDCP and also the option of an SDI input. The CS-1 lists for $500 more than the Iscan HD and the CS-2 lists for $1000 more. The SDI input is an additional sum.
I would think that there must be some feature and performance differences that make it financially viable for DVDO to carry a product with such a large price difference from a near competitor. Can you explain how the IScan HD is likely to differ from the CS models - in ways other than price? Here's the sensitive question: Where will the IScan HD fall short?
I'll compare the iScan HD to the CS-1, and concentrate only on the areas where the iScan HD might 'fall short' of the CS-1's features or performance. I've chosen the CS-1 for 2 reasons: 1) It's probably the closest to the iScan in both price and features (at least from a high-level viewpoint, and 2) We have one of these in our lab so I can make direct comparisons.
As nearly as I can tell, here's where the iScan HD will offer less than the CS-1:
1) The iScan won't scale a DVI input signal greater than 480p or 576p.
Caveat: We're looking to add this as a software upgrade, but I certainly can't promise it. It may be possible; it may not. This is a potential advantage of the iScan's programmable video processing hardware, but at this point it is just that - potential
2) The iScan HD has one less component input port.
Caveat: The CS-1 has 3 component input ports. 2 are used for interlaced, while 1 is used only for SD progressive signals. The iScan has 2 component input ports, either one of which can accept interlaced or progressive SD signals and which auto-switch between modes and to pass-through when the component source is HD. I suspect some users would prefer the latter setup to the former.
3) The iScan HD has an external power supply (i.e., a 'wall wart' or 'brick'). The CS-1's power supply is internal with a detachable IEC power cord.
4) The CS-1 has a better front-panel display than the iScan - more (but smaller) characters.
5) The CS-1 has a 12V trigger output. The iScan does not.
6) The CS-1 will probably
support a higher output pixel clock rate than the iScan HD. The iScan's pixel clock generator currently only goes up to 133MHz.
Caveat: We working to increase the pixel clock frequency by the time the iScan ships. We want it to do at least 150 MHz. Again, I can't promise this, but it is a possibility.
That's all I can think of. I'll skip the list which does the opposite comparison because there's no way I want to type that much. :D
