New Audio Codec Suggestion?

R

Ray

Evaluating purchase for a couple of Comrex Bric Link III versus the new Tieline Bridgeit II audio codecs.

Simple requirements for us: analog or AES3 audio, Bi-Directional, Dual LAN Fallover desired.

Biggest issue for us is going through Firewalls, NAT translations etc for public Wi-Fi at remotes. Tieline has their TieLink service and Comrex has their Switchboard service but I'm not sure which is most capable for easy internet connections at public events.

Seems like both models have great following.

Approximately same cost for either unit.

Any comments appreciated.

Thanks Ray
 
My experience is it depends on the use. If you're doing sports from stadiums, Tieline probably has the best solution. If you can afford the cellular card option, that's a nice backup: Tieline VIA Portable Codec
If the need is an STL that needs to be nailed-up all the time, then Comrex Briclink or Worldcast devices are excellent.
 
For remote broadcasts like sports coverage, I have used a Comrex at the studio end and a laptop or tablet running Linphone (an open source app that will run on Apple, Windows, Linux and Android) )in the field. The laptop was connected to the internet by using my cell phone as a hotspot. Solid connection and good quality. You can even run Linphone on a smart phone for spot news coverage. The open scource Opus codec provides full-duplex connectivity and excellent quality> It is available and Comrex and probably on Tie Line.
 
From my experience, when using either Tieline's TieLink service or Comrex's Switchboard service, when the needed TCP and UDP ports are disabled on the firewall, they won't work.
 
I have had experience with both Comrex & Tieline for remotes and sporting events. Besides the Tielink or Switchboard services, you might consider the data bonding algorithms. Comrex’s is called CrossLock. It takes the number of data paths you have on each end and it establishes that number of connections, I.e. if you have two data services on each end, there are four data paths established. The software constantly analyses each data path and chooses the best path(s) for each moment. This greatly aids reliability. Tieline has a similar algorithm. You can then use, as suggested, a wireless LTE modem for at least one of the connections on the “remote” end. Using LTE eliminates the problem with closed ports when using someone else’s network.

The most effective and trouble free remotes use two LTE modems (one per independent carrier) along with two data circuits at the studio end, each having access to the LTE carrier’s networks without traversing the Internet. This can prevent data bottlenecks and allow quality of service to be satisfied, also aiding reliablity. About the only thing that can prevent this scheme from succeeding is an unplanned event that overloads the wireless network. A disaster or a major league sports team victory parade come to mind.
