Using the new Datapath VisionSC-SDI4 with the signals that a TV broadcasters are giving us, we have some problems. I sent a ticket to Datapath with this information and I'm waiting for a reply.
Specification of the PC - including processor speed
PC Player for Dataton Watchout – i7-5930K; Motherboard X99; 16 GB RAM; SSD Samsung 128GB for SO; SSD Samsung 256GB in Raid0 ; FireproW7100 4Gb Graphics Card
Windows 7 Pro 64 bits
Dataton Watchout v6.1.5 but we check the same problem using the Vision Window from Datapath software (at full screen window mode)
Datapath Hardware / Software:
2 units of VisionSC-SDI4 with last VisionInstall_v7141 installation driver (after the installation, the firmware of the cards were updated by the program)
The exact nature of the problem:
We’ve installed in each WATCHOUT players 2 units of VisionSC-SDI4.
We are receiving 8 SDI signals in each player – One Capture board unit has 4x 1080i @25fps; the other capture board has 4x 576i @25fps
In the Vision Window of Datapath (Datapath software - in full screen at 1920x1080p) we notice a problem in the top of the image of animated loops and conventional images with some speed. We tried all the 8 inputs ( 4 HD and 4 SD) with different source images, HD and SD and all the inputs have the same problem.
If the datapath window of the software is smaller that the full screen, we don't see the problem occur.
Using Dataton software we see the effect in a lower place in the image; the bottom part field it's first to appear, that the top field part.
If I trim the top of the signal (1, 5 or 10 pixels), the place of the division of the image will be near the top, always at the same position (indepndently if it's trimmed 1, 5 or 10 pixels).
Apply frame blending of the live video input doens't change this.
Please see the photos and videos of the link:
We have the new 55VH7 LG Videowall displays connected to the output of the FireproW7000. At the beginning we had the output to the Videowall monitors at 1920x1080p @ 60Hz. After changing all the type of set up We changed the output of the PC graphic card to 1920x1080p @ 50Hz (to tried to see if with 50Hz that is the double of the 25Hz the system had a different result, we check and uncheck the "Aplly frame blending" in both refresh rate with the same result).
But the problem continues.
All the HD_SDI signals came from a broadcast system on the Broadcast Rack. We’ve connected a HD-SDI monitor to the same cables and we don’t have this problem. We've connected the same sigmal to a Blackmagic SDI>HDMI connected directly to the videowall monitor and it's OK.
At the Source desk they don’t have any configuration to change, because we receive the same signal from a HD-SDI distributors and the other connected equipment receive the signal perfectly.
It looks like a sync problem. They asked if we can put a REF signal in, but we can’t do that in the VisionSC-SDI4
Did you had this kind of problem in a capture card using Watchout? What was the way to solve?
