UHD with closed captioning

PostFri May 19, 2017 7:47 pm

I have a Teranex Express and need to frame convert an UHD signal. I have a question regarding the close captioning.

Is it possible to connect an UHD input source with cc? First tests show the input signal didn't include the cc data (no cc led). With HD input and cc all fine.

Hi Luc,
Yes the Teranex Express will support CC on UHD. We support the same 708 spec used for HD. If we detect any 708 packets on the incoming UHD video we will light the CC led on the front panel.
