I'm not sure what you mean by 35 steps to generate a Blu-Ray video disk ISO image. Are you talking about doing the compression too? How does the image get from a camera (or another device?) to your device? If you're talking about something somewhat akin to a nanoFlash unit, 35 steps sounds like a whale of an underestimate to me.
I don't see a point to generating NTSC SD output, to send to a TV station broadcast truck. Analog broadcasts shut down last week.

....No. No. My unit will capture a firewire HDV signal, or a 10 BIT HD SDI signal, and simply record that to an SD card *in HD* of course. To make the Bluray .ISO image, my unit will have to grab the video recorded on the *single* SD card and then pull that back into the unit for post processing if user presses .ISO button; then data is *converted* to the other format and spit back out to the SD card, thus erasing it - OR - data is pulled from one SD card socket and processed into Bluray image, then delivered to an SD card in *second* socket. (I think this is the more elegant way of doing it, but more costly to build) The second way would leave the originally captured video data fully intact on the original (read first socket) SD card.
With firewire capture of HDV material, things are straight, simple, and cheap, since the Long GOP MPEG 2 encoding is NOT done in our box, but in whatever HD camera and delivered (Streamed) to an SD card socket - OR - / - AND - sent to our crazy video encoding engine (NOT MPEG 2 Long GOP). The steps to creating a . ISO Bluray image must be programmed into the right capacity EPROM Chiparoo and the software written for it must carefully and perfectly carry out each step of the process, then move onto the next step and so on and so on until all audio, video, TC error checking, redundancy calculations are run. There's more too, but I won't get into that yet.
What can I say, it's a hobby, it's a business, it's an obsession, and it will get done, because I think it would be so cool to create my very own custom made SD Card DDR camera capture VTR replacement thingy. (Actually, it's slowly bankrupting me, but that's OK cause I will eventually get my dough back and then some !)
My proto-type cost is now estimated @ $30,000.00 Canadian ! Heck ! It's more than I thought, but still doable at this point. :-)
