Netflix updated its video encoding to make downloads look better
From time to time, Netflix updates the technology it's using to convert and compress each of the digital copies of movies it streams to customers. Because people watch from so many different platforms, in so many different situations, it has to be ready for any number of possibilities. Late last year, it revealed the use of a smarter way to apply compression, recognizing that different types of content (animation like Bojack Horseman vs. dark action scenes in Daredevil) need different levels of bitrate or resolution to look their best. Now it's focused on enhancing the efficiency of compression, starting with the video it delivers to mobile devices.
Making TV shows in 8K is about to get a lot easier
If you want to broadcast a TV show in 8K resolution, then you're going to need a whole room full of computers to encode the image. After all, a regular machine would struggle to process the 60, 35-megapixel images that need to be crunched every second. That's one of the many reasons that 8K video is currently limited to tech demos and the odd, one-off special event where the cost is justified. Japan's NTT, however, is claiming to have squeezed that room full of tech into a single box that's roughly the size of your average server module. Right now, the announcement is just that -- an announcement -- but this could mean we start seeing 8K broadcasts popping up well ahead of schedule.
Netflix's new video approach looks better, uses less data
The last time we noted Netflix extensively discussing how it stores video for the best streaming performance, its HD quality maxed out at 720p, surround sound was still a pipe dream and tablets weren't a thing yet. A Variety report explains that after extensive testing it's going through and re-encoding the entire library with a process that applies compression in a smarter way to maximize quality and save a ton of bandwidth. Soon, when you press play Netflix's servers will do a better job of recognizing what kind of device you're watching on and, depending on the connection speed available, pick a stream that fits its capabilities.
NHK and Mitsubishi develop the first H.265 encoder for 8K video
NHK's 8K Super Hi-Vision is an extremely bandwidth-heavy format -- so much so that earlier tests used gigabit-class internet links rather than traditional TV broadcasting methods. Thankfully, both the broadcaster and Mitsubishi have developed an encoder that could keep data rates down to Earth. The unassuming metal box (above) is the first to squeeze 8K video into the extra-dense H.265 (HEVC) format, cutting the bandwidth usage in half versus H.264. Its parallel processing is quick enough to encode video in real time, too, which should please NHK and other networks producing live TV. We'll still need faster-than-usual connections (and gigantic TVs) to make 8K an everyday reality, but that goal should now be more realistic.
UltraViolet movie format to use Dolby Digital Plus encoding, keep sound thumping across platforms
Movies encoded in UltraViolet's Common File Format represent just one of multiple takes on paid internet video -- what's to make them stand out? The answer might just be Dolby Digital Plus audio encoding, which should be a staple feature of CFF from now on. A newly ready development kit lets producers feed the multichannel sound to hardware and apps that can recognize it, including web-based avenues like Apple's HTTP Live Streaming, Microsoft's Smooth Streaming and MPEG's DASH. Just in case a few devices fall through the cracks, Dolby is talking directly with digital production firms like castLabs, Digital Rapids and Elemental Technologies to make sure the audio codec's implementation truly spans platforms. We don't know how soon movies will take advantage of the upgrade, but the Dolby addition lends weight to a fledgling format that might have as fierce a battle in home theaters as it does on PCs and tablets.
Raspberry Pi lands MPEG-2 and VC-1 decoding through personal licenses, H.264 encoding and CEC tag along
Making the Raspberry Pi affordable involved some tough calls, including the omission of MPEG-2 decoding. Licensing fees alone for the video software would have boosted the board's price by approximately 10 percent. Now, after many have made media centers with the hardware, the foundation behind the project has whipped up a solution to add the missing codec. For $3.16, users can purchase an individual MPEG-2 license for each of their boards on the organization's online store. Partial to Microsoft's VC-1 standard? Rights to using Redmond's codec can be purchased for $1.58. H.264 encoding is also in the cards since OpenMax components needed to develop applications with the functionality are now enabled by default in the device's latest firmware. With CEC support thrown into the Raspbmc, XBian and OpenELEC operating systems, a single IR remote can control a Raspberry Pi, a TV and other connected gadgets. If you're ready to load up your Pi with its newfound abilities, hit the source link below. Update: The Raspberry Pi Foundation let us know that US customers won't have to pay sales tax, which means patrons will only be set back $3.16 for MPEG-2 and $1.58 for VC-1 support, not $3.79 and $1.90 for the respective licenses. We've updated the post accordingly.
MPEG drafts twice-as-efficient H.265 video standard, sees use in phones as soon as 2013
All of that squabbling over H.264 may be rendered moot in the near future. The Motion Picture Experts Group (better known as MPEG) has just let us know that it was quietly drafting a new video standard while everyone was on summer vacation last month: H.265, also called High Efficiency Video Coding, promises to squeeze video sizes with double the efficiency of H.264. As you might imagine, this could lead either to a much smaller video footprint for bandwidth-starved mobile users or a hike to image quality with the same size as before. Imagine fast-loading HD streaming on 4G, or cable TV without all the excess compression, and you've got the idea. Ericsson Research visual technology lead Per Fröjdh anticipates H.265 coming as soon as 2013, when our smartphones and tablets are most likely to play it first. TV and other areas might have to wait, although Fröjdh is offering a consolation prize -- he's teasing a separate MPEG project that could give us glasses-free, compressed 3D video as a standard by 2014.
Dolby ups TrueHD lossless audio on Blu-ray to 96k, says every upsampled bit is amazing (video)
Just because your home theater can handle lossless audio doesn't mean the sound is as good as it could be. Dolby is now giving Blu-ray producers using Dolby Media Producer Encoder v2 the choice of premastering TrueHD surround sound at an upsampled 96k. Along with just squeezing the most possible clarity and depth out of 48kHz audio, the encoding purportedly eliminates some of the harshness of digital sound through an apodizing (signal altering) filter. At least three projects have already been given the 96k treatment, and authoring firms like Technicolor have upgrades in place to give that noticeable boost to your next Blu-ray movie.
Fujitsu Laboratories wants to take your mobile's 2D videos to another dimension
Fujitsu Laboratories has developed technology that will let any phone grab pictures and video with some of that third-dimension spice. Using a small attachment with cleverly positioned mirrors, the widget sits atop your phone's plain old 2D camera and breaks the incoming image into two. Once the data has been grabbed, you then send it off to Fujitsu's servers, whereupon it'll be converted into a 3D format. This isn't the first 2D-to-3D idea, but the main advantage, of course, is that your poor phone doesn't have to do all the leg-work -- but it undoubtedly comes at the expense of some quality. The gadget will get properly announced at the IEEE ISCE conference in Harrisburg on June the 4th along with pricing and availability. In the meantime you can step into the Japanese dimension -- i.e. the press release -- below for more info.
iTunes 10.6 adds option to sync 192kbps, 256kbps audio
According to AppleInsider, Apple snuck in two new bitrate options into iTunes 10.6 for users who sync their iTunes library to their iPhone or iPad. Most audio tracks are encoded at 256 kbps if they're bought from the iTunes Store, and now you can keep that quality when you send your files to your iOS device. Starting with iTunes 10.6, users can choose to sync their tracks at 256 kbps, 192 kbps or 128 kbps. This new setting gives users the flexibility to select the right encoding to match the storage of their device and their preferred audio quality. Audiophiles with a 64 GB device won't have to sacrifice audio quality, while less discerning users with 16 GB of space can choose to sync a smaller, lower bitrate file.
USB-IF releases extensions to USB video class 1.1, offloading compression is a go
For those unaware, a USB video class describes a device that's capable of streaming video -- you know, things like webcams, camcorders, TV tuners and even still-image cameras. For the longest time, you needed to rely on your machine to do the grunt work associated with encoding video, but new extensions to the USB video class 1.1 have enabled those very devices to support H.264. In other words, H.264 encoding can now be offloaded to the device itself, and furthermore, the compression provides more bandwidth for additional USB devices. We're told that the H.264 Payload specification is compatible with drivers based upon the USB-IF's UVC 1.0 and 1.1 specifications and relies on proper support of the MJPG and/or Stream Based payload format, and if you're an engineer looking to integrate, the goods you need are stocked away in the source link below.
StripeSpotter turns wild zebras into trackable barcodes
We've heard plenty of stories over the past few years about tagging animals with RFID chips, but we've never been particularly keen on the idea. Well, now a team of researchers has come up with a much less invasive way of tracking individual animals -- specifically zebras -- by essentially using their stripes as barcodes. StripeSpotter, as it's known, takes an isolated portion of a photograph of a zebra and slices it into a series of horizontal bands. Each pixel in the selection is then fully converted into black or white, and the bands are in turn encoded into StripeStrings, which eventually make up a StripeCode that resembles a barcode. All this information is stored in a database that allows researchers to directly identify particular animals without ever having to get too close. StripeCode may be a zebra-centric application for now, but its developers see it making a mark across the food chain with the inclusion of other distinctly patterned beasts, like tigers and giraffes. Animal tracking hobbyists can get their own free copy of the application by clicking on the source link below.
Fraunhofer working to make HD video conferencing a little less laggy
The early days of VOIP calling required a lot of patience, as the half-second or more delay between you speaking and your conversation partner receiving often turned the convo into a start and stop mess. Those days are gone for voice, but we're right back there again when it comes to HD video calls. However, random product researcher Fraunhofer is working on a new device to kill the lag and speed up your two-way monologues. It's basically an encoder card able to do hardware squashing of HD video via H.264 and audio via AAC, not unlike the sort of tech Skype requires for its SkypeHD-compatible video cameras. Fraunhofer's tech is also said to remove boomy room echoes and even handle network hiccups to keep you streamin' in style. The result is said to be sub-100ms lag, which would be more or less playable for a shooter. Expect more on this development soon from IFA.
WinFast HPVC1100 is world's first external SpursEngine encoder
Toshiba's Cell-based SpursEngine HD video co-processor has made plenty of appearances within monstrous gaming machines, but this marks the very first time where it has stepped out of the laptop chassis and into a portable enclosure. Granted, the language barrier is killing us here, but it seems as if the Leadtek WinFast HPVC1100 wraps a SpursEngine encoder into an on-the-go solution that can be lugged around with a standard laptop in order to churn through video while on set, in the field or on the road. Other specs include 128MB of RAM, a PCI-Express slot and a weight of 1.54 pounds; there's no word just yet on pricing or availability. One more shot is after the break.[Via Akihabara News]
H.264 encoder coming to PS3
Here's another way to harness the power of the PS3's Cell chip. Fixstars Corporation of Japan has announced CodecSys CE-10, the first H.264 encoder that's designed specifically for the PS3. The product will be showcased at the National Association of Broadcasters show in Las Vegas starting April 20th. The CE-10 software will be installed on a PC, but will somehow allow users to access the power of the PS3 as a way of accelerating video encoding. Fixstars is promising "ultra fast HD encoding" and "high quality low bit rate compression," targeted at the prosumer market at a prosumer price.When questioned further on how the PS3 would interface with the CE-10 program, we were provided this rather useful document (pictured above). It appears the PS3 will need Linux installed, severely limiting its accessibility to all but hardcore PS3 owners. Considering the rather specific demands of this application, perhaps that makes sense. CE-10 will be available for purchase in June 2009. For burgeoning HD filmmakers, this should be a very cheap way of turning the PS3 into a powerful piece of video hardware. Also, did we really just say "prosumer?"
DivX 7 gets January 2009 release date
There's not much to on besides a teaser page right now (okay, so there's only a teaser page right now), but here's the important part: DivX 7 is coming, and it's due next month. The next-generation of the software promises "true HD video" with H.264 video and AAC audio, and apparently it'll present something akin to "a cinematic experience" on your computer. Pretty bold claims there -- thank goodness we've but a matter of weeks to determine if it lives up to 'em or not.
Netflix CPO gets technical about encoding for streaming
Go on, confess. If you're reading this now, chances are you have at least a passing interest in learning how all of this glorious streaming content actually gets to your TV set / computer while still managing to look at least halfway decent. If you're willing to be honest with yourself, there's a lot in the read link that you'll love. Without going too in-depth here (wouldn't want to scare anyone off, you know?), Netflix's Chief Product Officer covers the basics of first- and second-generation encoding as well as how it handles the wonderful high-def encodes that are used to deliver Watch Instantly content to the Xbox 360. Oh, and now that the New Xbox Experience is live, you can chime in below and let us know if all that hard work that's being done behind the scenes is paying dividends on your HDTV.[Via CNET]
QuickTime H.264 Compatibility Update is out
Apple just released a software update for QuickTime. The update titled "H.264 Compatibility Update" claims to improve QuickTime compatibility with iChat.You can download this update by opening Software Update (Apple menu > Software Update), or by downloading the installer package directly from the Apple website (it should appear there shortly). Thanks to Tony, and others who sent in this tip!
RipIt yanks your DVDs right off the disc
HandBrake handles most of my DVD-ripping responsibilities just fine, but RipIt came to our attention recently, and as a simple one-touch way to get a movie off of a DVD and on to your hard drive (in order to, say, watch it on a laptop without lugging the disc itself along), it looks pretty simple. In fact, it's about as cake as these things get: load up the app, throw a disc in your drive, and press Rip -- a few minutes later (a 7.9gb rip took about 30 minutes for me), you've got a DVDPlayerMedia file on your hard drive to watch at your leisure. It's $18.99, which is pricey, especially (again) compared to HandBrake, which is conveniently open source, and provides tons more ways to rip things. But if you do a lot of movie ripping and want to have one single button rather than worrying about formats or encoding, that $19 might be well spent.
JVC announces MPEG-2 / H.264 dual codec LSI chip
As the camera / camcorder world continues to embrace video sharing sites, it's no surprise to see this little critter emerge from the labs of JVC-Victor. The pictured dual codec LSI chip handles both MPEG-2 and H.264 / MPEG-4 AVC formats, theoretically cutting out the painful encode process from YouTube uploads. Granted, most of the technobabble behind the thing is lost in machine translation, but we do get the idea that it'll start showing up in the outfit's Everio line shortly.[Via AkihabaraNews]
