#2Cool stuff. Good to see them recognize and use advantages of analog. I could tell them digital transmission of data has always been done with analog circuits but analog's invisible ubiquity is beside the point. ;)

#3Does this allow encryption of the video stream? Graceful signal degradation is a great feature, but I don't see how that would work when there is encryption.

Encryption won't work for this scenario as it reintroduces the problem of all or no data. Degraded encrypted data can't be decrypted successfully (yet?)

Amen. Now if someone could get DVDs or streaming services to offer fast-forward and rewind that works as well as a VCR we'd be caught up to the 1980s!

encrypt with a redundant parity data?

Hell yes! Or even hardware acceleration for starting in random parts of videos on my PC so they don't break up and delay as often. This is the digital era. It's supposed to work more reliably than old, analog tech. I used to be able to stop my rewind or fast-forward on VCR within a few seconds of the target moment with clean play. Still not reliable with digital streaming. (sighs)
Note: I do like how, even with errors, it still takes under 20 seconds for me to get to any random part of the vid. That's an improvement over the rewind/fast-forward speeds. :)

Even then I think it would still be all-or-nothing. That may increase the chances of "all" over "nothing" but not allow graceful degradation of the video.

#9> Note: Before using wifibroadcast you have to check if the regulatories of your country allow such a use of wifi hardware.
Any guesses as to whether this would be legal in the US?
