NASA Will Conduct First Ever Live 4K Video Stream From Space



NASA Logo4K video streaming is definitely here to stay. In fact, 4K streaming is becoming so commonplace, it’s even possible to now stream live 4K video from space. That’s exactly what NASA is going to do during the 2017 NAB show, happening later this month in Las Vegas. NAB recently announced via mass e-mail that the space-vid stream will occur during a panel called Reaching for the Stars: Connecting to the Future with NASA and Hollywood:

The panel is co-produced by NAB Show, NASA, and Amazon Web Services (AWS), and will explore how advanced imaging and cloud technologies are taking scientific research and filmmaking to the next level. The live feed from 250 miles above Earth will be encoded AWS Elemental encoding software on board the International Space Station (ISS) and on the ground at Johnson Space Center.

During the NAB Show Super Session, a live 4K stream will enable NASA astronaut Dr. Peggy Whitson on the ISS to converse with AWS Elemental CEO and Co-founder Sam Blackman, who will be at the LVCC. In conjunction with the live 4K streaming event, NASA astronaut Dr. Tracy Caldwell Dyson and NASA Imagery Experts Program Manager Rodney Grubbs will take part in an LVCC-based panel discussion featuring Hollywood and technology leaders…

This presentation should appeal to video-production professionals and space/science buffs alike. The presentation will take place on Wednesday, April 26th from 10:30AM-11:30AM at spaces N249-251 during the NAB Show at the Las Vegas Convention Center. The presentation will also be live-streamed in 4K (with downscaled versions available for non-4K devices) and made available on-demand after the presentation is over.

4K, 8K Test Broadcasts Carried Out By NHK



NHK LogoTime waits for no one. Nor does the inevitable progress of higher-resolution video. It still feels like true HD video has just barely been normalized here in the United States. And yet the push beyond HD, into 4K and even 8K, has begun. The latest example of the move forward comes from Japanese public broadcasting agency NHK (also known as Japan Broadcasting Corp.) as the company has begun testing both 4K and 8K broadcasts.

Of course, most viewers who can tune into these test broadcasts won’t really be able to see the full depth of the video transmissions, as 4K video is still riding the bleeding edge of consumer technology, and 8K is little more than a pipe dream today. Regardless, NHK will have public displays of the technology available at its broadcast centers across Japan.

NHK is hoping to make 4K and 8K video a regular part of its broadcast set by 2018. The broadcasting company hopes this move will help popularize the new formats in the lead up to the 2020 Olympic Games and Paralympics in Tokyo.

Traditionally, Japan has always been ahead of markets like the U.S. in terms of adoption of new technology. So there’s a good chance NHK will meet its goal in time for the Olympics. 4K TVs are currently available in most markets and are priced affordably. But I couldn’t find any estimates on what an 8K set might cost.


Fuji Has 4K 2/3 Lenses at NAB



Fuji Film LogoFujinon is a well respected manufacturer of camera lenses. Fujinon was recently tied more heavily to its parent company, Fuji Film. It’s a small change in name only. The Fuji folks are still hard at work creating new top of the line products.

Thom Calabro from Fuji Film stopped by to speak with Don Baine about Fuji Film’s latest 4K lenses. These lenses were designed with 2/3 sized camera bodies in mind. The company has developed both handheld and box lenses that were on display in the Sony, Hitachi and Grass Valley booths at NAB.

These new 4K lenses are built sturdy and will last for years. They also use Fuji Film’s new high transmittance encoding to ensure the best image reproduction.


Nvidia Brings Improved 4K to its Flagship Video Processor



Nvidia logo4K video is old news to media professionals. And even tho there have been plenty of products built from the group up with 4K in mind, there are still a lot of legacy manufacturers that need to catch up. Nvidia is a leader in the video processing world. And while they’ve offered some 4K products already, the company believes they still have some improvements to make in how their products handle ultra HD signals.

This week, Nvidia unveiled what is soon to become its next flagship video processor, the GeForce GTX 980 Ti. This new card will deliver better support for 4K resolution, allowing for 45 frames per second, compared to 19fps on the older GTX 680. In heavy graphics intensive situations, Nvidia says its new card can go even higher, all the way to 47fps at 4K on the GTX 980 Ti compared with 18fps on the GTX 680.

This new video processor is powered by Nvidia’s Maxwell microarchitecture, which supports the latest DirectX 12 effects. Video RAM has been upgraded to 6GB of memory compared with the previous card’s 4GB. This new Maxwell chips allow for high-resolution performance and lighting with better frame rates combined with better power efficiency. The GTX 980 requires half the power consumption of Nvidia’s GTX 750, which was powered by the first version of the Maxwell chipset.

The new version of Nvidia’s card will retail for $649 and the introduction of the GTX 980 Ti has also caused the price of the former flagship model, the GTX 980, to drop to $499.
