Such was
the attraction of the special UHDTV exhibition, and the main exhibition area,
that attendance in the main sessions today was more modest today than
yesterday. Though there was still
interesting technology to hear about.
They
included the developments in the ATSC on a system for providing emergency
warnings to users of the ATSC’s mobile system.
If there a hurricane coming, your mobile TV can switch itself on, and
give you all the details. It seems
though that take up by the industry has so far been modest. That’s the problem with things you only need
very occasionally, but when you need them, you really need them.
There was
also a presentation about technology to allow a broadcaster to increase the
number of channels carried in a multiplex, which could silently and secretly be
used for carrying content to a consumer or a daughter broadcaster. The
idea is that you discretely reduce the bit rate of the normal channels for a while, and
slip in the extra channel or content. No
new equipment is needed. Could it be
that the technical quality we broadcast could be raised or lowered depending on
the audience size - like adaptive internet streaming in reverse?
For the
UHDTV exhibition itself, there were many UHDTV monitors, comparisons of quality
after compression, and more. Maybe the
SMPTE 2013 will go down in history as the day the story of UHDTV finally broke?
