Question Bi-directional HDMI extender?

I've got an interesting need. I have a Cisco RoomKit, which has two major parts. The camera/speakerbar, and the codec.



The camera/speakerbar sends video out to the codec; the codec sends audio to the speakerbar.

In my environment, the two devices are seventy feet apart. I'm currently using a Redmere HDMI cable, with the codec on the receive end. It works, but I get occasional video dropouts, so want to replace the RedMere cable with a different solution.

Unfortunately, the bidirectional need of this configuration disqualifies the standard type of extender over CAT-5/6.

Suggestions on a viable option would be appreciated.

Thanks,

-Jack

 

So, a little more research... looks like my solution will be to use an HDMI extender which supports ARC (Audio Return Channel). I'll update this forum post if it works out.
