MPEG has not one, not two, but three tracks for developing unencumbered or RF-only encumbered video, as an experiment.  I think there are a few people at MPEG who think that this optimization direction -- for cost of license -- is clearly applicable to some cases, and should be followed.

The need or bandwidth-saving at any cost -- the old optimization direction -- is slackening, IMHO.  Sometimes you want to optimize battery life (complexity), sometimes license cost, and so on.

There are not enough people, in my opinion, working on this at MPEG.  Getting involved, helping, would be good.
