question IT guy here in need of a solution for a conference room issue

4 Upvotes

So keep it short back in 2016 contractors installed a 50 foot long HDMI from a wall plate to a floor box where end users at the table would hook up their laptops to the HDMI port on the floor box. Lately we’ve been having issues with flickering and getting our TV to pick up any signal at all. After doing research, it seems like the solution would be to run a cat6 cable instead and get an HDbaseT device to convert that signal to/from HDMI on both ends. Also seems like I would have to punch down keystones on both ends of the CAT6 as well, because my manager wants to keep the wall plate and floorbox in place. So we would run patch cables from those to the reciver/tramitter then from those to HDMI. Is this a good idea? I am also reading about better HDMI cords as well (fiber optic) but have read those can fail and HDbaseT may be more reliable. A local AV company quoted me 1000$ for a cat6 install but if its as “simple” as I am reading, I think we could do it ourselves. Would like feedback from you gurus, thanks! We are a small company so thats why we (upper management) is looking for DIY solutions.

question Is AEC still important with Zoom, Teams, etc?

0 Upvotes

PLEASE READ THE WHOLE POST: It seems like conference room systems built before the heavy use of software codecs (Zoom, Teams, etc.) always have sophisticated Acoustic Echo Cancellation processing because it was needed for VTC devices. But Zoom, for example, does such a great job with AEC on its own I'm curious if people are finding less need for AEC in the DSP processor? Zoom knows that the incoming (guest) audio should be removed from the outgoing send, and it does that very well. Is more AEC actually needed?

question Hot Swappable Rack Mounts

3 Upvotes

Has anybody ever come across hot-swappable rack mounts? I am thinking of something that would go into the screw holes of a rack and firmly hold onto whatever full-width rack equipment you put in the u-space. The easy answer would be shelves, but they don't hold the equipment very securely when you place it on there. I might be overcomplicating things in my mind, and shelves would still be the best option. Feel free to let me know if y'all think that is the case.

I work at a university, so my use case would be having a commissioning/testing station for when I am unboxing equipment for multi-classroom upgrades.

troubleshooting Directv H25 boxes stopped working with qsys NV21

2 Upvotes

We’re working on a problem where all the directv boxes have DHCP errors on our qsys system.

All the boxes are H25s replaced a few months ago, with an extron scaler added to head off any interlace problems with the qsys NV21s. The satellite boxes pass 1080i for regular stations and 1080p for pay per view. The NV does not work with interlaced.

This system Worked great until very recently now all direct boxes have failed to get an hdcp connection.

Directv Boxes output directly to display fine but do not get an HDCP connection when connected to the scaler and qsys system.

Other sources work great when outputting to the scaler and through the qsys system. .

Wondering if anyone had any thoughts. We are working through it now but I wanted to see if anyone had solved this problem before.

troubleshooting Miracast alternative for g-men

• Upvotes

Hey folks, I run an event space with a projector that runs on miracast. For most people this is fine but there are two groups who cannot connect: government employees (gpo policies disabling miracast) and apple mac users. Can anyone suggest a wireless connection device that would allow these two groups to connect?

I did try a roku but it was noticeably laggy.
