SMPTE 2013 - A historic event for UHDTV

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?
