| 09:39 | irieger | mithro: Yeah, I had a look at the Opsis board campaign the other day but was sad that it's only low res HDMI (not even 1080p) and Display Port which is pretty useless
|
| 09:40 | mithro | The DisplayPort is dual mode so you can connect HDMI to it using cheap adapters
|
| 09:40 | irieger | mithro Bertl_zZ : noone said my wishes are easy ones ;-)
|
| 09:40 | mithro | It does 1080p30 and 720p60 on the HDMI ports
|
| 09:40 | irieger | Ok. https://www.crowdsupply.com/numato-lab/opsis only lists 720p or 1024x768
|
| 09:42 | irieger | I don't get what the Opsis is aiming for. For real video use SDI is the connection you want.
|
| 09:43 | irieger | (I hate HDMI since on one project we killed 4-5 mini-HDMI -> HDMI adapters in a week)
|
| 09:43 | mithro | SDI is too expensive
|
| 09:44 | irieger | Why is it expensive? Would have thought that a simple BNC is much easier than this multi pin HDMI ports?

| 14:59 | antiatom | joined the channel |
| 15:04 | cbohnens | Bertl: I did not follow the whole conversation, but I talked to the financial and idiological backer behind the usb2tv project, and AFAIK the limit is USBv2.0, not the transceivers
|
| 15:04 | cbohnens | I might be wrong there though
|
| 15:06 | cbohnens | (this was while intoxicated during cccamp in Mildenberg, so please don't quote me on that)
|
| 15:16 | intracube|away | changed nick to: intracube
|
| 15:18 | mithro | Bertl: they run at ~3.2Gb/s each and you have 4 lanes
|
| 15:39 | Bertl | so we could run 4 SDI 3G per DP port then, yes?
|
| 15:39 | Bertl | i.e. four in and four out
|
| 15:56 | mithro | Bertl: I guess so? I don't know much about SDI
|
| 15:59 | Bertl | http://www.xilinx.com/support/documentation/application_notes/xapp1076_S6GTP_TripleRateSDI.pdf
|
| 16:02 | Bertl | and a cable driver like the LMH0302/0303 might be sufficient to get SDI out (similar for SDI in)

| 19:05 | irieger | Bertl: I hope that the 6G/12G-SDI standard will be finalized soon. By all this 4K hype in the industry it's strange it takes the SMPTE so long ...
|
| 19:06 | Bertl | well, you would need to have 4x 3G SDI anyway
|
| 19:08 | se6astian | 6G SDI has been standardized lately I heard
|
| 19:11 | irieger | Bertl: why?
|
| 19:14 | irieger | se6astian: Interesting. Haven't hear anything. Blackmagic and some others have 6G/12G products on the market but they are not really working together as they aren't based on a common, finalized standard
|
| 19:14 | se6astian | irieger: likely because the GTX on the opsis are limited to 3.2Gbit
|
| 19:15 | irieger | Ok, in this case. But I see Quad SDI as an impractical solution for many stuff. Way too much cables. One cable makes cable management so easy
|
| 19:17 | Bertl | that's why we use HDMI/DP :)
|
| 19:26 | se6astian | wikipedia says SMPTE ST-2081 covers 6G-SDI: ST 2081-1 (electrical), ST 2081-2 (optical), ST 2081-10 (single-link mapping)
|
| 19:27 | se6astian | 2082 is then about 12G SDI
