標題[情報] Sony to launch 4K video distribution

LAS VEGAS--One of the big problems with 4K TVs right now, aside from the fact
that it's tough to discern any benefit from their extra resolution, is lack
of content. Sony, alone among TV or content providers so far, actually aims
to tackle that issue around the same time it launches its full line of 4K TVs
later this year.
This summer the company will set up a dedicated video distribution service to
deliver 4K content to the home, complete with a hardware 4K Video Player that
can feed the TVs directly.
Currently buyers who pony up $25K for the company's 84-inch 4K TV are
"loaned" a video player (essentially a big hard drive) pre-loaded with 4K
video content, including ten feature films and a gallery of video shorts. But
this is the first we've heard of a 4K delivery system and presumably it will
offer access to significantly more 4K content, without the kludgy BD-ROM
delivery method required to update content on the loaner player.
In addition, Sony also announced a few Blu-ray discs newly remastered in 4K.
Crucially, however, these won't be actual 4K Blu-rays -- they'll have normal
1080p resolution, and be playable by any normal Blu-ray player to any HDTV.
Pricing for the 4K video player, the 4K content it would play, and the
4K-mastered discs was not disclosed, but it's safe to say none of it will be
cheap. I also asked about delivery methods; hardware details; whether the
content would be stored locally or streamed; compatibility with other
devices; output formats; and whether content would be rented, owned or both.
I was given no additional information beyond the company's press release:
To my knowledge Sony's service will be the only way owners of 4K TVs (Sony or
otherwise) will be able to view actual 4K content in the home, save that
"loaner" and at least one minor exception. Given that a 4K Blu-ray standard
has yet to be adopted; that there's no 4K broadcast standard yet for
over-the-air, cable, or satellite delivery; and that there isn't even an
official HDMI standard that supports the resolution, Sony's service will
arrive remarkably early.
Hopefully we'll be given further details later at the show.
