I'm too lazy to answer the exact question, but power draw should be
quite small.
Lazy or just beyond your ability to address since few if any of us
know how much power these receiver chips will draw. The first gen
chips we have seen are power pigs. Power cycling is not a huge
benefit as you must monitor the entire stream to find the segments
you need.
The larger problem is the complexity of the receiver, especially the
equalizers needed to make this scheme work.
The good news is that most people only need to access short bursts of
video content today on their smart phones and other mobile receivers.
The bad news is that the broadcast model does not fit well with what
people want/need. Access on demand is what the market wants and the
Internet provides. This can be done with broadcast using local
caching to update services to which the mobile device "subscribes."
Thus a receiver could be trained to cache a broadcast weather report
or new headlines...
