BBC promises five new HD channels by early 2014, including News, CBeebies and BBC Four

Posted on 16/07/2013 by Sharif Sakr

Not that they weren't pretty excellent already, but some major BBC channels are due to get 1080-line upgrades by early next year. UK viewers will get five new channels in total, with no need for any subscriptions (courtesy of Freeview HD, YouView and Freesat), including BBC News HD, BBC Three HD, BBC Four HD, CBeebies HD and CBBC HD (so long as Mr Tumble can fix his make-up). The programming will match the standard-def counterparts and contribute a promised 250 hours of extra HD content per week. There's also talk of broadcasting regional programs and variants in HD, although that proposal still has to be approved by the BBC Trust and could be a bit further off.

Sony Stitch merges footage from two 4K F65 cameras to create zoomable panoramic with HD output (video)

Posted on 07/09/2012 by Zach Honig

Well, that's a mouthful of a headline. Going a bit more in-depth, a new professional solution from Sony allows broadcasters to capture side-by-side 4K video at, say, a sporting event, then use a standard camera zoom device to select small portions of each feed for 720p or 1080i output. On the receiving end, you'll see a live image that looks indistinguishable from something you'd capture with a moving camera, with a few extra benefits to boot. Sony demonstrated the system using feeds from an F65 4K camera earlier this year at NAB, but was only able to present a simulation at that point, with pre-recorded output cropped from larger-format footage.

Now, as we saw today at IBC in Amsterdam, the technique works in realtime, so an adjustable smaller portion of the video is pumped out seamlessly and instantaneously. The 4K video can also be recorded at full resolution simultaneously, letting you change the framing long after an event takes place. Sony only had the demo configured to pull live video from the left portion of the feed, but eventually the entire capture will be enabled, giving producers access to an entire football field, as you'll see in the hands-on video after the break. We wouldn't expect this solution to replace human camera operators anytime soon, but it's certainly a viable method for adding angles and placing a bit more control in the hands of production teams, even after the fact.

This is what native 4K home cinema looks like on Sony’s VPL-VW1000ES projector

Posted on 17/05/2012 by Sharif Sakr

Why are folks so keyed up about 4K? At first glance, that's the type of question that answers itself: by definition, a 4096-pixel wide image delivers around four times the resolution of 1920 x 1080, and that's a healthy multiple. It's actually of a broadly similar magnitude to the difference between 1080p and old-fashioned analog NTSC video, and nobody these days questions the value of that upgrade. On the other hand, there must come a point where pixels cease to be visible in a home theater environment, such that buying more of them at inflated prices stops being worth it. Sure, 4K can be a big help with 3D footage, because it boosts the resolution to each eye -- something we experienced with the REDray projector. But what about regular 2D material, which is still very much the default viewing option? That question's been nagging at us, so when Sony invited us back for a second look at its 4K projector, the VPL-VW1000ES, this time with full-throttle native 4K source material rather than just upscaled 1080p, we turned up with a tape measure. Read on for what came next.

NHK makes first successful Super Hi-Vision OTA broadcast, man cave owners giggle with glee

Posted on 17/05/2012 by Jason Hidalgo

Fresh off from successfully shrinking its Super Hi-Vision camera, Japan's NHK is sticking another feather in its cap -- the first over-the-air broadcast of its super-duper high-resolution technology. The broadcaster says it recently managed to send a compressed Super Hi-Vision signal from the roof of its Science and Technology Research Laboratories in Tokyo to a distance about 4.2 kilometers away with no issues. NHK used two UHF channels during the experiment. To optimize and boost transmission capacity, NHK leveraged technologies such as orthogonal frequency-division multiplexing (OFDM) and multiple-input multiple-output (MIMO). Low-density parity check coding was also used for error correction. NHK has been constantly experimenting with its Super Hi-Vision high-resolution (7,680 x 4,320) video format, including a UK-to-Japan broadcast via a 24Gb/s internet connection in 2010. Folks who happen to be in Japan from May 24th to 27th can check the tech at the NHK labs' open house in Tokyo's Setagaya ward.
