It is highly relevant. Both entered the digital camera business along
with many other CE and film based camera companies.
Irrelevant. One sells primarily the consumable product, film, the other sells
the durable goods, cameras.
I suppose it might be possible to build improved 8-VSB receivers today;
Very possible. There are at least two aspects that can easily be improved:
1. Improved dynamic multipath performance, using the Limberg/Patel/McDonald
patent, and probably similar other approaches. Where the flatness of the
spectrum and the short duration of the symbols is used as an asset instead of a
liability.
2. Better use of the existing Viterbi and Reed-Solomon FEC, where they are used
together instead of being used in series.
We've gone over these ideas many times in the past. The latter should gain at
least ~1 dB of marginal C/N margin, which makes it quite respectable against
any competition. And all of this is done with no impact on products out there,
or on the FCC's planning factors.
Adding h.264 or h.265 can be done with little effort.
I'd leapfrog H.264. This is a one-way broadcast standard. There is NO reason to
have to support too many different modes. Totally different story than if it
were a 2-way unicast service.
The telcos no longer determine smartphone features.
And once again, this is false. The telcos definitely do determine still. Even
if some feature may be installed in the phone, the telcos very much do disable
them, if they so wish. Even something as innocuous as FM receivers get disabled.
