Broadcasters Not So Eager to Switch to UHDTV

Broadcasters Not So Eager to Switch to UHDTV | Ultra High Definition Television (UHDTV) | Scoop.it


There's a lot of discussion about 4K--also known in the broadcast and consumer electronics worlds as UHDTV--production and whether it is practical for broadcasters to distribute 4K signals--it requires four times the bandwidth of current 1.5 Gbps infrastructures to get into the home.


Broadcasters covering live events have utilized the technology as part of an overall HD sports telecast in order to provide viewers with captivating high-resolution, slow-motion replays and critical analysis of disputed plays.

With little demand from consumers for UHDTV sets, however, it might take a while before we see activity in this space at the local OTA station level.


Indeed, with 4K content now available on YouTube, it's entirely possible that viewers will be watching UHDTV content via the Internet well before it can become a viable broadcast standard.

Japan’s public broadcaster has successfully broadcast long-distance digital terrestrial signals for its Super Hi-Vision 8K format, sending massive amounts of data over UHF airwaves, but despite this test it’s unclear if many Japanese will be watching 8K TV by the time Tokyo hosts the Olympics in 2020.


Nippon Hoso Kyokai (NHK) Science & Technology Research Laboratories conducted the test from its bureau in Hitoyoshi, Kumamoto Prefecture, in southern Japan, and managed to send the 8K Ultra High Definition TV signal to a receiving station 27 kilometers away using a single UHF channel.

Making Room for UHDTV

Making Room for UHDTV | Ultra High Definition Television (UHDTV) | Scoop.it


We discussed the many aspects of UHD including larger color space, high dynamic range, higher frame rates in addition to the increased resolution.
I talked about how at Iowa Public Television, we work in an uncompressed environment when creating shows in our studio and how that has simplified our infrastructure.

But as I look forward to implementing UHD, even at a relatively small facility, the laws of physics and the laws of economics seem to be conspiring against the concept of the uncompressed backbone.

By Bill Hayes, director of engineering for Iowa Public Television.

TV Makers are out of Ideas

TV Makers are out of Ideas | Ultra High Definition Television (UHDTV) | Scoop.it


From 3D to 4K to curved screens to Sony's 6758.TO -3.12% strange "wedge-shaped" sets (don't ask), we are witnessing an industry out of ideas, a business desperately casting about in the dark for something—anything—that might persuade us to part with our money.

The death of innovation in TV hasn't come about because TVs are perfect.


Far from it.


It remains a big hassle to find something you want to watch, or to stream TV shows and movies without consulting a handful of remotes, or to navigate your cable system's byzantine menus.


Indeed, in our modern, multidevice, multi-subscription-service livings rooms, almost nothing is as easy as is it needs to be.
