surami
would it be possible to connect a coaxpress board to the Beta somehow? i'm just reading about that technology
15:13
Bertl
yes, it would be possible
15:15
surami
here is a document about the chipset: http://ww1.microchip.com/downloads/en/DeviceDoc/60001302A.pdf
15:16
Bertl
well, that's an equalizer sec
15:16
Bertl
*set
15:16
Bertl
it is important for the cable part, but it still requires the actual Coaxpress interface
15:17
surami
oh, i see
15:18
Bertl
but the interface is basically SDI, so not that problematic
15:18
Bertl
I would suggest adding the link to the lab or wiki though
15:19
surami
ok, i will
15:20
surami
some weeks ago here were somebody, who could
15:20
surami
help you out with a framegrabber design
15:20
danieel
Bertl: cxp and sdi share about as much as pcie and sdi :)
15:24
Bertl
as you know all the electrical interfaces and the protocols very well, you might want to document them on the wiki :)
15:27
danieel
what for? a comparison table might be handy, but if you want to know the interface, the best is to read its standard... otherwise a lot of false information gets mixed in
15:27
Bertl
linking to those standards would be benefitial there
15:28
danieel
the issue is that some are non free - that would need to be solved first
15:28
danieel
(at least the SD has a free variant - without UHS)
15:28
Bertl
well, link to the free ones then, and note for the others that they a non-free
15:29
danieel
well.. i am not sure if there is any really free one - one that can be used without being part of a certification group
15:31
danieel
the specs about interfaces - most of them are on wikipedia, is there a need to double that info?
15:32
Bertl
all standards can be used without being part of a certification group
15:32
Bertl
there is no such thing as a forbidden standard
15:32
danieel
how do you obtain a VID then ?
15:33
Bertl
yes, obviously there is a need to collect this information, as wikipedia does not list the electrical and encoding specs in a neat table somewhere

Bertl: what about Camera Link HS?
21:04
surami
or Camera Link "Full" mode?
21:05
Bertl
what about it?
21:07
slikdigit
left the channel
21:08
surami
i meant a custom designed camera link board attached to the Beta
21:08
Bertl
yes, would also be possible

21:24
surami
so this different protocols could be connected to the left/right side io shields?
21:24
surami
i don't understand technically
21:25
surami
or there will be a highspeed protocoll on the Beta?
21:25
Bertl
there is a high speed shield, and a general purpose I/O shield
21:26
Bertl
the high speed shield will at least connect 16 LVDS pairs with at least 1GBit/s per lane
21:27
Bertl
this can be used to to connect certain interfaces directly and other interfaces via high speed serializer/deserializers
21:29
surami
well I have to search things on the net to understand this :)
21:29
surami
but thank for the explanation
21:30
Bertl
no problem, let me know if you need more information

23:42
surami
how much hdmi ports will be on the Beta and what type?
23:44
surami
i'm thinking again on the 4k raw capture
23:44
surami
if the 3 color channels could be delivered separetly
23:45
surami
on 3 different hdmi ports
23:45
Bertl
we have a 3xHDMI shield planned, which would allow for FullHD on each port
23:45
surami
60fps?
23:46
Bertl
should be doable, yes
23:46
surami
and hdmi 1.4?
23:46
surami
:)
23:46
Bertl
probably not, because HDMI 1.4 requires higher pixel clocks
23:47
Bertl
i.e. HDMI 1.4 adds 4kx2k modes
23:48
surami
so 1.2
23:48
Bertl
we plan to support a single high pixel clock HDMI shield
23:48
Bertl
that one will probably be HDMI 1.4
23:49
Bertl
yes, 165MHz (pixel clock) is most likely the maximum for the 3x HDMI shield
23:49
surami
the color channels could be separeted on the fpga side and delivered separatly to HDMI ports?
23:49
Bertl
yup
23:50
g3gg0
left the channel
23:53
surami
if the raw data is "filtered"
23:53
surami
with 3 different channels
23:53
surami
r,g,b
23:54
surami
it would be only noise on a HDMI display?
23:54
surami
could the raw data separeted this way, 3 channels?
23:55
surami
or the raw data should be processed first?
23:55
surami
to do something on 3 channels?
23:55
Bertl
you do not even need to split it into r,g,b
23:56
Bertl
it's fine to send 3 sensel to the first HDMI out, 3 sensel to the second, 3 sensel to the third and so on and so forth
23:56
surami
sensel?
23:56
Bertl
(that's what we plan for recording 4k over 3xHDMI
23:57
Bertl
)
23:57
Bertl
sensel = photo sensitive element, can be R, G or B
23:57
Bertl
(in our case)
23:57
surami
aha
23:58
surami
so in theory with a capturecard this data could be transfered something visible?
23:58
Bertl
yup
23:58
surami
i mean 3 hdmi input
23:58
Bertl
as long as the capture card captures raw data without lossy compression
23:59
surami
i found a card
