From AVB to AvB to A_B
For the third straight year, I’ve attended InfoComm with the expectation that someone, somewhere would have actually developed and implemented IEEE 802.1 AVB (Audio Video Bridging) to its full potential. As in, implemented it into a product that exploits (A)udio and (V)ideo.
Sadly, I return home again, empty. Admittedly I didn’t look as hard this year as I did in previous years, likely due to the fact that I didn’t find much last year and hope has been on the wane.
What did I find at InfoComm 2012? Biamp has an A_B solution, Tesira; Sennheiser previewed an A_B microphone. And, there were others. There was also an AVB booth on the show floor where a number of audio manufacturers touted their involvement and intent to produce hardware, some of which did, indeed, look very interesting.
Hey, it’s nice to have a newer digital audio networking technology with lower latency, greater bandwidth and higher channel count. I’ve even vetted my first A_B design, in an application which could not have been done as efficiently with other technologies. So there are things to look forward to. Just not AVB.
But I continue to watch this little ship twirl in the back eddy, with little prospect of joining the mainstream of the audiovisual industry. I now realize that I’m not the one suffering from wasting disease; it’s the standard that’s wasting away. I’m still sick, just heartsick. But I’ll recover.
After all, sticks and stones may break my bones but incomplete acronyms will never harm me.
