mouniroo Posted September 11, 2021 Report Share Posted September 11, 2021 Hello Watchout community family, Hope you are all doing well. i would like to input 8 signals hd coming from the same PC and same graphic card. I am planning to take 2 x watchpax 40 and use 8 ndi newtek spark to input the signal. What do you think ? any suggestions of another way to input the 8 signals ?

RBeddig Posted September 12, 2021 Report Share Posted September 12, 2021 Well, you should be aware of the bandwidth of NDI signals. https://support.newtek.com/hc/en-us/articles/217662708-NDI-Network-Bandwidth In NDI networks, senders and receivers need to be counted. I.e. 8 senders sending 1080p60 to 8 receivers will need around 2.000-2.500 Mbps bandwidth in your network. If you go down to NDI-HX (more latency, higher compression), you'll cut this roughly by 1/10th. Quote Link to comment Share on other sites More sharing options...
wiesemann Posted September 12, 2021 Report Share Posted September 12, 2021 Do you need to see them all at the same time, all the time? Otherwise you could switch before going into Watchout, saving bandwidth.. Quote Link to comment Share on other sites More sharing options...
mouniroo Posted September 14, 2021 Author Report Share Posted September 14, 2021 Hi RBeddig, thank alot for your reply...it s very clear.. my output is coming from the same graphic card (1pc) and the information doesn t looks so heavy as it is for coming from an sql database so only TEXT and black background .........i might do some testing .. in case i have issue i will connect it directly to my LED PROCESSOR in DVI and use the HDMI input for watchpax for the other contents.... Dear Wiesemann, YES same time . Quote Link to comment Share on other sites More sharing options...

If it's rather static, you could also give the "Computer Screen" media a try. It's basically VNC and will probably give you not more than 12-15fps.
