Issues with the SDI to HDMI 4K

Hi everyone,

I recently bought the SDI to HDMI 4K for purposes of a live demo streamed accross campus via the Sony IP55's. I am having issues with quad link 1.5G SDI 1080/50i inputs into the converter. it is not wanting to work with the IP55's at the moment, is this an issue with the signal type, or could it be the converter itself?

Thanks

Sam

According to the website the "NXL-IP55 allows you to transmit up to four genlocked HD video streams (three downstream and one upstream, or two downstream and two upstream)"

That means it can only transmit 3 streams in one direction, not 4 so I don't think it will work.

hi chad,

I am using two seperate IP55's at each end of the stream to allow for 4 signals to be sent.

Cheers

I don't think you can use 2 separate streamers like that. For the 4K signal to work, all 4 signals must be in perfect genlock, a single streamer can do that because it can "mux" all 4 signals together in a single "packet". However 2 separate streamers by definition would be in 2 separate packets (one per streamer) which means those packets would almost never arrive at the same time to keep them locked. Unless the streamers have some kind of way to all sync to each other.

The streamers are capable of using both a reference signal and the SDI signal to sync the boxes. It also has the option of syncing using the Network that it is connected too. They are designed to work with either 2 boxes transmitting to two boxes or 3 to 1 and 1 to 3. Alongside this, they are also intended for local cross campus tests.
