Dont know if some one is online(awake), just a question, im thinking about building a HDMI to SDI and SDI to HDMI, it is not the easiest thing to do i know. But just wanted to know what you guys think of that and if you have any experience with doing similar things. I know allot about Electronic design but im a analog guy, was never so into FPGAs etc. but this would be something to learn from.
02:20
Bertl_oO
yeah, you definitely need an FPGA for this kind of stuff
02:22
Konstantin
i know
02:22
Bertl_oO
do you have a deisgn for the actual conversion process? do you want to convert on the fly or buffer a whole frame?
02:23
Konstantin
but the question is how big/fast it has to be
02:23
Bertl_oO
that depends on the resolutions you want to support
02:23
Konstantin
on the fly would be nice to save the memory and therfor alot of pins
02:24
Konstantin
for a start 1080 would do the trick
02:24
Bertl_oO
p25/p30/p60/p120? :)
02:24
Konstantin
60p
02:25
Bertl_oO
so that is about 1.5Gbit encoded HDMI data
02:25
Konstantin
jup about the 3g
02:25
Bertl_oO
(per TMDS channel, that is)
02:25
Konstantin
standart
02:26
Bertl_oO
that can be done without MGTs for output, but probably tricky for input unless you want to use specific chips
02:26
Konstantin
hmm
02:26
Bertl_oO
are you planning an FPGA only solution?
02:27
Bertl_oO
if so, I would make sure that you have at least 8 MGTs
02:27
Konstantin
Probably ore Interface with an AD chip on the HDMI site
02:28
Bertl_oO
yeah, that's the other way to address that
02:28
Bertl_oO
have specialized HDMI/SDI in/out interface chips
02:28
Konstantin
hmm 8 hope to get a sens full page
02:28
Bertl_oO
in this case the FPGA doesn't need to be fast or feature MGTs
02:29
Konstantin
ok that is what i thougt for using such chips
02:29
Konstantin
but have to see if i can even get them
02:29
Bertl_oO
but of course, you lose some flexibility
02:30
Konstantin
rigth too
02:30
Bertl_oO
yes, they are readily available, from analog devices, the 7611 and 7513
02:30
Bertl_oO
for SDI the Texas Instruments LMH* series
02:31
Konstantin
yes the HDMI
02:31
Bertl_oO
LMH0340 is probably the best choice here
02:32
Konstantin
did not knew the LMH series
02:32
Konstantin
ohhh yes thats what i was looking for the LMH seams nice
02:37
Konstantin
i will look into it witch solution migth work best, to do it in one FPGA might even be ceaper or using combination some other Serializers can be "missues" to serialize SDI
02:38
Bertl_oO
keep us updated on your progress
02:41
Konstantin
i will could be usefull maybe for some of your stuff, and maybe later a more powerful version but 1080p 60fps is good for a start ^^
02:41
Konstantin
se ya later
