MPEG group working on AVC replacement for Ultra High Definition video of the future
The tech around Super Hi-Vision technology may not be completely worked out yet, but with that on the way, plus HD for mobile devices and even more streaming, the 88th meeting of the MPEG/ISO standards group in Maui was apparently a busy one as attendees voted to work on a new, better form of compression to replace MPEG-4 AVC. "High Performance Video Coding" (HVC) is just a dream at the moment, but be sure to pencil that in as one more spec to look out for in the future. Of course, they didn't mention a delivery system for 22.2 channel audio, but we'll just assume that's being handled as well.[Via EE Times UK]
RED blows away small room of videophiles with 4k RED RAY footage at half the bitrate of MiniDV
While RED has been pretty tight-lipped about its planned RED RAY product, some footage shown off at RED's NAB party gave a sizable hint that RED RAY could be much more than meets the eye -- specifically a $1,000 device that can play cinema-quality 4k video off of standard DVDs. At the party they played an uncompressed showreel of 4k footage on a Sony 4k projector, which clocked in at 1.3GB per second, and then showed that exact same footage under the "RED RAY" codec at a mere 10Mb/s (megabits, not bytes; about half the bitrate of SD DV), at a compression rate of 700:1. Attendees claimed they could see zero visible compression, though a projector in a ballroom isn't exactly the best case scenario to test that sort of thing. Unfortunately, there's little other info about how they're achieving this (we hear "wavelets" come into the equation at some point), or to what nefarious aims, but with compression like this the implications for content distribution are pretty stunning: 1080p+ streaming for all. Naturally, the down side of all of this is probably some pretty hefty processing power on the consumer end, but we'll cross that I/O bridge when we come to it.[Thanks, Ben H]
Fixstars CE-10 encoder puts Playstation 3 to work on h.264 video
Maybe you don't do enough video conversion to make copping a dedicated SpursEngine card a good investment, but that doesn't mean you can't put the Cell processor in your PlayStation 3 to work in between sessions of Killzone 2, (not like it's busy curing cancer or anything.) Fixstars' CE-10 encoder doesn't exactly fit the "Cell Storage" pie in the sky promises of yesterday, but by installing it on a PC it lets users tap into the PS3's number crunching power to achieve professional encoding quality. No word on what an "affordable prosumer price" is, but if ultra fast HD encoding is something you'd be interested in -- those 1080p vids won't compress themselves -- stop by the Broadcast International booth at NAB next week for an early preview before the software launches in June.
Rogers reportedly implements more compression on HD channels
Sadly, we don't have any reason to believe that this is some nasty April Fool's prank. We heard right around this time last year that Rogers Cable was looking to pull a Shaw and compress its HD signals even further, and now, it seems that said smashing has begun. According to Digital Home, a "majority of all Rogers high definition channels measured are now being compressed." Investigation in the matter has found that around 60 percent of Rogers' HD channels in Toronto were compressed, with HBO, The Movie Network, MPix, Nat Geo, CBS West, ABC West, Fox West, NBC West and PBS suffering the most. We're told that those stations saw typical bitrates of around 10Mbps to 13Mbps, while Rogers SportsNet, CityTV, CBC, CTV, Global and Discovery HD saw streams between 16Mbps and 18Mbps. Any locals care to confirm / deny?
Cable HD compression gets turned up a notch in the Electra 8000 encoder
We haven't talked about QAM cramming much recently, but we have a feeling its ugly, pixelated head will soon be raised once more, now that Harmonic is launching the DiviCom Electra 8000 encoder, capable of stuffing four MPEG-2 HD streams in one QAM channel. It might be an interesting bit of hardware if you're a head end tech, capable of delivering 1080p60, MPEG-4 and MPEG-2 video capable of three encoding passes, but all we can see at the end is too many channels slotted into too little frequency and the potential for compression artifacts. Anyone stopping by Cable Show '09 this week should be able to get a demo, with the first units shipping in June, we'll be keeping a close eye on both our channel lineup and picture quality.[Thanks, Larry]
Turbo.264 HD adds AVCHD transcoding savvy
When first we met the Turbo.264 hardware compression accelerator, it did a great job of speeding up video exports on older CPUs but didn't offer a tremendous boost on modern Intel hardware. True, it worked well with Elgato's EyeTV software to transcode TV recordings overnight for iPod or iPhone use, but not everyone needed to spend the money to recover that time.Elgato's got an upgrade to the Turbo hardware now, the Turbo.264 HD. On the one hand, the new unit is limited to Intel Mac owners running Leopard -- leaving out the G4 and G5 users who benefited most from the speed boost of the older unit. On the other hand, the widget has the ability to export in HD resolutions; you can do basic trim edits on clips and handle almost any input format under the sun. More importantly, the new stick brings a vital feature to HD camcorder users: on-the-fly transcoding of AVCHD video.Mac users who have AVCHD camcorders have suffered long and loudly with the format, even though native editors like NeoScene and batch converters like VoltaicHD have simplified things a bit. While iMovie '09 and Final Cut/FCE can handle AVCHD, importing is a slow slog. The Turbo.264 HD promises to dramatically reduce importation time for AVCHD clips and offload the work of transcoding them from the computer's processor. If it works as advertised, it's going to be very popular with HD camcorder users.The new unit is $150US and shipping now.
First Look: Video Monkey swings in to save the day
When Techspansion closed its doors in October of last year, there were hordes of individuals clamoring for a slice of easy video-conversion pie to fill the void in their now-empty hearts. Many did not find consolation in the fact that Handbrake supported universal input within a scant two months. An application that offers every configuration option available is all well and good for many fine folks; but there are some of us that want this type of thing to be simple. What I and others desired so greatly was a video-conversion app for the rest of us -- and that application was VisualHub. Enter Video Monkey. Following the release of Tyler's source code for VisualHub as the TranscoderRedux project, one lone soul, named Chris, decided to brave the trepid waters and save all of us from drowning in a sea of videos awaiting conversion for our iPhones and AppleTVs. Chris makes it perfectly clear that Video Monkey's mission is inspired by, and borrowed from, Visual Hub. However, while Visual Hub relied heavily on AppleScript, Video Monkey is written exclusively in Cocoa. After Chris got in touch with TUAW, I got right to work checking out this holy grail of simple video-conversion applications. Read on for my first impressions and initial thoughts or just check out the gallery.%Gallery-47761%
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]
Techspansion closes, VisualHub discontinued
There are plenty of Mac tools for video compression in the marketplace, ranging from Windows Media-oriented tools (Flip4Mac) to professional workflow builders (Sorenson Squeeze) to hardware-assisted H.264 crunchers (Elgato turbo.264). Few of these products, however, have hit the sweet spot of wide-ranging capability, quality output and extremely affordable pricing like VisualHub from Techspansion. For less than $25, you got Flash and WMV output that rivaled products 3x the price, plus easy conversion to iPod and iPhone-friendly formats. Along with sister apps audio compressor AudialHub and iPod-only video converter iSquint, VisualHub was a prime example of a well-built, "Mac way" media app.Sadly, the past tense above is no accident. Techspansion's website has been shuttered and the products have been discontinued. Tyler Loch (Techspansion's founder) let us know that the difficult decision to close down Techspansion is a personal one, and he's readjusting his priorities to focus on other needs. His choice is understandable, but we will definitely miss VisualHub (not to mention the laugh-out-loud funniest release notes in software history). Best of luck to Tyler in his future efforts.Update: For those who are inquiring, there are no current plans to move VisualHub to open source. The underlying engine for much of the compression magic, ffmpeg, is already open-source and present in other Mac tools such as Handbrake.Thanks Brandon
AT&T will increase HD compression on U-verse
Good news, U-verse fans, you'll be upgrading from the current 2 HD / 2 SD video stream system to three live HD streams in 2009. The (potentially) bad news is that comes with the price of additional compression, as AT&T's IPTV service squeezes its MPEG-4 video streams down to 5 Mbps from a current size of 6-8 Mbps, according to CTO John Donovan. Count another bonus as the Total Home DVR will throw as many as seven video streams around the house, up from the current five. With a last mile DSL strategy that gives it less breathing room than Verizon's FiOS, there's only one way to add more streams, but is there going to be a PQ price to pay? We'll find out soon, and don't expect AT&T to stop there, Multichannel News quotes Donovan saying encoders currently in development could reduce bandwidth even further.
Popular Mechanics gets wise to HD compression
Around Engadget, we're all too familiar with the evil bit starving ways of some content providers and local affiliates in the name of the bottom line. But it's always good to see the more mainstream press get wise as Popular Mechanics has a good article on the why and why not, our HD signal is over compressed. The most interesting new piece of information is something we've heard of in the past, but it's good to get additional details, which is HBO's requirements in regards to what a provider can do with its signal. We assumed the requirements would specify a minimum bit rate, but in reality it is a limitation of what other content can be carried on the same QAM channel. So that means no sports, animated content, or any other bit hungry content for that matter. Ultimately, all this talk just makes us enjoy our Blu-ray Discs that much more.

Poll: Have you been affected by over-compressed HD feeds?
Talk about an onslaught. Within the course of a few weeks we've seen Shaw, Rogers and Comcast all get flamed for purportedly compressing their signals to a point beyond acceptable, and as if that wasn't enough, a recent research report found that video quality issues (shocking, we know) were the primary reason for call-in complaints. All the while, Verizon is taking the chance to toot its own horn and boast about its ability to pass along HD signals sans additional tweakage. So, are you right in the middle of this firestorm? Or are you gleefully looking in from the outside with a gorgeous HD picture on your set? Give us your story below, won't you?[Image courtesy of Vidiot] %Poll-12224%
HD compression goes under the microscope
Considering the recent hullabaloo over Comcast and Rogers Cable deciding to (over) compress at least part of their respective HD lineups, Electronic House's latest writeup is particularly timely. It's investigation into HD Lite reveals quite a few tidbits that everyone should know, but often get overlooked in the uproar. Put simply, every high-def channel that gets piped your way is compressed in some form or fashion (that includes you too, Verizon) before it hits the carrier. In other words, just because a signal gets modified before it hits your set doesn't automatically make it HD Lite. Still, there's no doubt that some providers have taken this squeeze too far and compressed signals to the point of noticeability -- that's where the problem emerges. Give the article a read, you'll likely learn a thing or two about nomenclature if all else fails.
Verizon FiOS TV spot boasts of "uncompressed" HD
It was inevitable, really. No sooner does Comcast and Rogers Cable begin taking heat for over compressing their HD feeds than Verizon pumps out a TV spot trumpeting its ability to deliver "pure, uncompressed high-definition." The ad campaign asserts that its delivery of material is superior to that offered up by traditional cable providers, but the company's media relations director Bobbi Henson did note that the real purpose was to show that "FiOS TV customers are receiving HD that's not compressed by Verizon." She noted in an e-mail statement that "content owners compress their video before sending it to video service providers, but [Verizon] forwards the signal to its customers the way that [they arrive]." You know what they say about bandwidth: if you've got it, flaunt it.
Rogers Cable to implement more compression on some HD signals
Bad news for Rogers Cable customers -- word on the street has it that your HD feeds may begin to look a little less fantastic in the coming days. According to Digital Home Canada, the carrier has outlined a plan in a technical briefing sent out by Rogers Network Engineering and Operations that will compress part of its high-definition lineup in order to "deliver more HD channels without having to use more bandwidth." As it stands, 15 HD channels are facing the dreaded HD Lite treatment effective April 9th, but curiously, we're not told which HD networks are actually on the docket to be added. Granted, we've yet to see a definitive confirmation, but given that Comcast has recently caught loads of flack for its decision to shove three HD channels on a single 6MHz slot, we suppose an awful trend could be (re)emerging. Keep a critical eye out, Rogers customers -- let us know if anything changes.[Thanks to everyone who sent this in]
Comcast rolling out Science, Disney and ABC Family HD channels
Comcast is stepping up its busy HD rollout (and channel squeezing) schedule, with several new channels spotted today in the Detroit and Chicago areas. Science HD, Disney HD and ABC Family HD are probably in your local channel guide -- Discovery HD is now listed DSCHD, while Disney is DISHD, confused yet? -- and word is they should hit many other areas Wednesday. Posters at AVSForum indicate more of the 3 channels-on-one-QAM compression tactics are afoot, take a look and let us know if having High School Musical 2 in HD still satisfies.[Thanks, Nathaniel]Read - Detroit, MI HDTVRead - Chicago, IL Comcast
Poll: Are you satisfied with your HD service?
After breaking things down as best we could this week, we noticed a flood of comments from critical HD consumers about the quality (or lack thereof) of their HD service. Of course, it's impossible for us to take a look at each provider out there and assess just how wonderful (or not) its deliverance of high-definition programming is, so we figured we'd put it out there for all of you readers. Bottom line: are you stoked about the quality of your high-def service? If so, by all means, let the world know who's treating you right. If not, shout out what's keeping you from extolling your carrier -- be it a shoddy HD DVR, inexplicable compression, a high level of outages, a dearth of HD offerings or simply charging too much for too little. %Poll-9224%
RCN goes all digital in Chicago, shoots for 100 HD channels
Starting today, RCN will begin switching to all digital programming in Chicago, Illinois, a full year (and change) before all broadcast channels must do the same. Reportedly, the move will enable the cable provider to reclaim excess spectrum and recreate its cable offerings. More specifically, the 80 channel Signature package will be re-launching with 180 channels for the same price, and while we're not told exactly what new HD additions we'll find, a few newcomers are nevertheless promised. Additionally, subscribers in the area can expect more video-on-demand content and new channel pods which will purportedly "provide customers with the ability to pay only for the programming they want to watch." With all this freed up space, the firm's VP and General Manager Tom McKay has boldly proclaimed that it hopes to "make good on the promise of offering approximately 100 HD channels in the future," but sadly, "future" is as detailed as it got. 'Course, some users will need to grab a digital converter box or CableCARD to continue receiving service, but you already knew that, now didn't you?
Comcast Media Center gets creative with compression
Make no mistake about it, as the bandwidth belt tightens around cable, carriers are grasping for ways to cram more channels into an increasingly small space. Reportedly, Comcast Media Center has devised a method to stuff three HD signals into a single 6MHz carrier, which is typically just enough to handle two HD channels without picture quality taking a dive. Though the process sounds quite technical, the long and short of it is that a "second-pass MPEG-2 encoding system from startup Imagine Communications" is reportedly being used to "stack together three signals at variable bit rates into one 6MHz QAM channel." Of course, it's hard to say if this clever methodology results in noticeably poorer picture quality, but unless something drastic happens in the world of coax, you can count on seeing a whole lot more where this came from.
