NEXT TV and Orad break new ground with permanent stereoscopic virtual studio
With Orad's innovative broadcasting technology, Polish broadcasters, NEXT TV have broken new ground by broadcasting from a permanent, stereoscopic, virtual studio.
By combining Orad's Virtual Studio and Stereographic solutions, NEXT TV can easily set up their stereoscopic production. NEXT TV's Panasonic cameras produce two 1080i signals for each eye. The camera data is then tracked by Orad's DVP which calculates the cameras' positions directly from the Panasonic camera. A single Orad HDVG is configured to produce and key internally separate 1080i left and right eye signals. Orad's' unique stereo controller then allows the operator to ensure an exact match between the stereo properties of the virtual studio and the real studio.
The end result is an accurate, real time stereoscopic production.
NEXT TV will also be using Orad's stereographic technology in its new TV station. NEXT TV will be producing 3 channels that will be in full 3D HD.
"NEXT TV is thrilled to implement such an advanced technology. We pride ourselves in providing our viewers with the most exciting and compelling broadcasts and with Orad as our partners we will continue to be on cutting edge of broadcast technology", Karolina Szymańska, CEO, NEXT TV.

Industry’s Future Was on Full Display at 2011 Cable Show
By Todd Spangler -- Multichannel News, 6/27/2011 12:01:00 AM
The future of cable technology was in full view at the Cable Show here earlier this month. Concepts crystallized into compelling demos and, in some cases, actual products.
At the same time, the network of connections is getting faster and smarter to be able to accommodate the coming multiscreen, all- IP-video future. Broadband and digital-cable equipment vendors demonstrated that MSOs will be able to fully tap into the 1 Gigahertz spectrum available over hybrid fiber coaxial networks, yielding multiple Gigabits per second of bandwidth.
“There was little that was truly new,” Sanford Bernstein senior analyst Craig Moffett wrote in a post-show research note. “But shows like this year’s may have the more lasting import, as they often tell us more about where we are going over the next five years.”
Here’s a recap of what was on display in the Windy City, grouped into five areas of innovation:
Cable’s move to cloud-based user guides will allow new features to be introduced much faster than with traditional interactive program guides that are tightly bound to set-top hardware.
The most high-profile advance: Comcast CEO Brian Roberts’ demo of the “Xcalibur” guide, which provides personalized features, integration with Internet services like Facebook and Twitter and advanced searching.
It’s all delivered over the network, dynamically, by the mpx video publishing system from Comcast’s ThePlatform subsidiary. Pace developed a hybrid digital video recorder set-top box with Tru2way, DOCSIS 3.0 and IP-video capability, running a media processor from Intel.
“TV services have historically been defined by infrastructure equipment, but that’s changing,” ThePlatform CEO Ian Blaine said. “Moving forward, cloud computing will play a defi ning role in enabling TV-service providers to innovate and differentiate.”
The Xcalibur demo exemplified ThePlatform’s strategy of trying to nab a seat in front of the living-room TV. It has hooked up with networking systems vendor Alcatel-Lucent to pitch pay TV providers on a jointly developed solution for distributing video over Internet protocol to a range of devices, including TVs, PCs, tablets and mobile phones.
Other developments on the “cloud” front: EchoStar Technologies debuted “Aria,” an offering comprising over-the-top VOD and HD user interfaces delivered to hybrid cable set-top boxes. The proposition with Aria: to let smaller cable operators deliver 12,000-plus VOD titles, an HD guide and Slingbox features to customers, without requiring a large capital outlay for infrastructure.
Interactive video-application vendor ActiveVideo Networks demonstrated how HTML5 applications could be delivered to set-top boxes or any video-streaming decoder. The company’s CloudTV platform takes content stored, processed and rendered in the network cloud and delivers it as an adaptable-bandwidth video stream to a device, which then passes back user key clicks from standard remote controls, smartphones or tablets.
Rovi debuted an advanced guide application that rides on top of its i-Guide IPG and provides HD graphics, advanced search, recommendations and poster art, delivered over IP. The TotalGuide Application for Set-Top Boxes application shows users what’s on their favorite channels, and lets them search and browse by programs, celebrities, cast and credits across linear TV, VOD and DVR.
Rovi executive vice president of products Corey Ferengul said: “Our customers said, ‘Make this work with i-Guide — give us a richer experience, but don’t make us make a massive investment in new hardware.’ ”
The push behind technologies for enabling “TV Everywhere” is in full swing.
Motorola Mobility showed off the Medios Xperience platform, which is supposed to let service providers deliver video content, social networking, games and Web-based content on “companion” devices. The software is designed to tie into operators’ existing video- on-demand and linear-TV services. The Medios Xperience platform includes three pre-built services: TV and VOD remote; TV and VOD streaming; and an enhanced user interface.
The TV and VOD remote lets a tablet, smartphone or laptop function as a remote control to browse an enhanced programming guide, choose a VOD or linear title, and launch that title on their device or on any TV in the home. In tandem with that, the streaming feature lets subscribers watch live TV or VOD on a device and provides menubased social-networking options.
The user interface — which can be part of a service provider’s branded site — provides search, navigation and discovery of content such as movies and TV shows on second-screen companion devices. The UI features personalized recommendations and a Netflix-like watch-list queue.
Avail-TVN expects to kick off trials starting in July of a service designed to let programmers and their pay TV affiliates deliver live TV and VOD across a galaxy of different devices.
The company’s AnyView managed multiscreen-video service will deliver video in MPEG-4 format. AnyView uses the Apple-developed HTTP Live Streaming adaptive bit-rate protocol that detects a user’s bandwidth and device capacity in real time to deliver encoded files at the appropriate data rate. “It’s really taking that TV experience from video-on-demand and linear and bringing it to connected devices,” Avail-TVN chief strategy officer Doug Sylvester said.
There are other roads that lead to IP video, too: Separately, Motorola touted “Televation,” a Slingbox-like device developed with Comcast that includes a CableCard and real-time transcoding capability to spray live TV over Wi-Fi to IP devices anywhere around the home. (Comcast said it currently did not have specific plans to launch Televation.) Unlike Slingbox, the Televation device for now is designed for only in-home use.
Who needs fiber to the home? Cable’s ability to deliver mega-high-speed broadband was highlighted in the Comcast demo of a souped-up cable modem rig blasting more than 1 Gigabit per second downstream.
Comcast used Cisco Systems’ DOCSIS 3.0 cablemodem termination system with the 3G60 line card and two prototype 16-downstream- channel modems to deliver a peak speed of 1.084 Gigabits per second, running over a dedicated coax network segment in its Chicago system.
According to John Chapman, chief technology officer for Cisco’s cableaccess business unit, the demonstrations show that DOCSIS still has many years of life left. “In short, it means that yes, DOCSIS does continue to scale — in a big way, and for a long time,” Chapman wrote in a blog post.
Arris showed its C4 CMTS delivering real file-transfer throughput of 4.5 Gbps of DOCSIS 3.0 downstream traffic, as well as 575 Megabits per second upstream to a single fiber node. The demo used 16 DOCSIS 3.0 modems with 8x4 capability — that is, eight downstream by four upstream — bonding an aggregate of 128 channels down and 24 up.
No operator would necessarily want to deliver that kind of bandwidth to an individual sub, Arris senior director of solution architecture and strategy Mike Emmendorfer said. “Peak speeds are cool,” he said. “But what we’re seeing is the need to maintain capacity to keep up with overall growth.”
According to Cisco’s recently updated VNI Forecast, average broadband speeds worldwide will jump from 7 Mbps in 2010 to 28 Mbps in 2015.
Focusing on the upstream, Aurora Networks touted its digital return-path solution that promises to double DOCSIS 3.0 upstream capacity, although an MSO would first have to reclaim analog TV channels to take advantage of it. The vendor’s Universal Digital Return module uses the 54 MHz to 88 MHz spectrum, which historically has been used for analog broadcast television, essentially doubling today’s standard North American use of the 5-42 MHz return path.
CommScope launched what it claimed is the cable industry’s fi rst universal edge quadrature amplitude modulation solution that can span the full RF spectrum — up to 1 GHz — with the ability to deliver 160 QAM channels on a single port.
Why this is a big deal: It will give an MSO the flexibility to put any service anywhere in the spectrum, as opposed to being locked into specific frequencies on dedicated QAMs.
“Getting to 160 QAMs per port is kind of a magical number because you have all 158 QAMs available in the 5-MHz to 1-GHz band,” CommScope vice president of advanced broadband solutions Shane Eleniak said.
The LxS-16016 QAM system, to be available this summer, was developed by LiquidxStream, which CommScope recently acquired. The system provides up to 160 QAM channels on each of 16 RF ports, delivering a maximum of 2,560 QAMs in a four-rack-unit-high chassis, which easily beats other solutions currently on the market on scale and density.
CommScope is positioning the product, which supports any combination of video and data services across all QAMs, as aligning with CableLabs’ Converged Cable Access Platform, which consolidates the core interface requirements of Comcast and Time Warner Cable for an integrated headend device.
In a similar vein, Broadcom privately showed what it claimed is the industry’s first fully digital “full-band capture” tuner chip — able to tune anywhere in the 50-MHz to 1-GHz downstream spectrum. That promises to provide a lot more flexibility in how cable operators deploy the next generation of set-tops, gateways and DOCSIS modems that include the Full-Band Capture tuner. Here’s why: With the “FBC,” any demodulator can tune to any frequency — using just one chip instead of nine individual tuners.
Operators are turning their attention to hybrid vehicles to provide a way to bridge the gap between the current quadrature amplitude modulation-delivered cable TV world and full IPTV.
Motorola Mobility cooked up a six-tuner IP video gateway — with 1 Terabyte of disk storage — for Time Warner Cable. The DCX3600M Video Gateway includes built-in transcoding capabilities allowing it to take a single QAM MPEG-2 channel and transcode it to MPEG-4 for delivery to mobile devices, such as tablets and smartphones, over a home network. It also includes a DOCSIS 3.0 modem with eight downstream and four upstream channels.
“It’s truly the anchor tenant in the IP-connected home,” Motorola Mobility senior director of marketing Buddy Snow said. “I think this box embodies the kinds of features we spent the last two years talking to the cable guys about.”
Motorola did not disclose pricing. Snow said gateways are cost-effective options because they reduce the cost of delivering video throughout the home, “especially when you talk about fourth, fifth and sixth outlets. You could use a PlayStation 3 as a client.”
The DCX3600M can be configured as a “headless” gateway — meaning it doesn’t have a front control panel or TV-video outputs — or as a “headed” gateway that functions as a traditional set-top.
Six tuners is the magic number for gateways: Arris also was showing its sixtuner gateway with 500 Gigabytes of disk storage and a DOCSIS 3.0 modem with eight downstream and four upstream channels. The IP-enabled gateway uses the Moxi guide developed by Diego, which Arris acquired two years ago.
Not wanting to be left out, Cisco provided select customers a closed-door demo of a hybrid cable video gateway, dubbed “Generation 8,” designed to give operators a pathway to a full IP-based video infrastructure.
The G8 gateway likewise includes six QAM tuners. It has the ability to stream up to 10 live or recorded video streams inside the home over IP and includes a DOCSIS 3.0 cable modem with the ability to bond up to eight downstream and four upstream channels.
To deliver video to tablets and other non-set-top platforms, the G8 includes a transcoding engine to convert MPEG-2 into MPEG-4 H.264 format, with the ability to handle one HD stream or up to four standard-definition channels concurrently.
“You’re not going all-IP overnight,” Ken Morse, chief technical officer of Cisco’s Service Provider Video Technology Group, said. “This can extend your linear channels to IP devices and then provide the full lineup down the road. It’s a no-regrets investment.”
ADVANCED TV ADS
After years of talks and trials, advanced advertising is poking its head above ground.
Cablevision Systems touted the launch of Optimum Select RFI with e-mail fulfillment, which lets viewers click on an interactive 30-second spot and request more information via e-mail. Recent customers that ran ITV spots in the MSO’s New York metro service area included travel-promotions firm International Cruise & Excursions. The operator said Lincoln, Benjamin Moore and Adirondack Regional Tourism plan to begin RFI-toe- mail campaigns shortly.
On the VOD advertising front, SeaChange International and This Technology hooked up to combine SeaChange’s Infusion Advanced Advertising Platform with This Technology’s SpotLink software. The joint solution promises to let operators to use existing Internet ad servers for placement decisions for dynamic VOD ads.
Buzz at the Cable Show was that SeaChange has been in discussions about acquiring New York-based This Technology, according to two sources. (The companies declined to comment.) Meanwhile, SeaChange itself is an acquisition target, with Arris exploring a takeover of the VOD and advertising systems firm.
Meanwhile, Harris Broadcast Communications made its official entry into the VOD advertising space with its Targeted Advertising platform. An extension of its linear ad-management system, the software includes an integrated Campaign Manager module to handle the purchase and management of multiple advertising product types.
Among other developments on the advanced ad front: Black- Arrow, BigBand Networks and Nagra (in conjunction with This Technology) showed the ability to deliver targeted spots to handheld devices.
From NY Times: Atop TV Sets, a Power Drain That Runs Nonstop
There are 160 million so-called set-top boxes in the United States, one for every two people, and that number is rising. Many homes now have one or more basic cable boxes as well as add-on DVRs, or digital video recorders, which use 40 percent more power than the set-top box.
One high-definition DVR and one high-definition cable box use an average of 446 kilowatt hours a year, about 10 percent more than a 21-cubic-foot energy-efficient refrigerator, a recent study found.
These set-top boxes are energy hogs mostly because their drives, tuners and other components are generally running full tilt, or nearly so, 24 hours a day, even when not in active use. The recent study, by the Natural Resources Defense Council, concluded that the boxes consumed $3 billion in electricity per year in the United States — and that 66 percent of that power is wasted when no one is watching and shows are not being recorded. That is more power than the state of Maryland uses over 12 months.
“People in the energy efficiency community worry a lot about these boxes, since they will make it more difficult to lower home energy use,” said John Wilson, a former member of the California Energy Commission who is now with the San Francisco-based Energy Foundation. “Companies say it can’t be done or it’s too expensive. But in my experience, neither one is true. It can be done, and it often doesn’t cost much, if anything.”
The perpetually “powered on” state is largely a function of design and programming choices made by electronics companies and cable and Internet providers, which are related to the way cable networks function in the United States. Fixes exist, but they are not currently being mandated or deployed in the United States, critics say.
Similar devices in some European countries, for example, can automatically go into standby mode when not in use, cutting power drawn by half. They can also go into an optional “deep sleep,” which can reduce energy consumption by about 95 percent compared with when the machine is active.
One British company, Pace, sells such boxes to American providers, who do not take advantage of the reduced energy options because of worries that the lowest energy states could disrupt service. Cable companies say customers will not tolerate the time it takes to reboot the system once the system has been shut down or put to sleep.
“The issue of having more efficient equipment is of interest to us,” said Justin Venech, a spokesman for Time Warner Cable. But, he added, “when we purchase the equipment, functionality and cost are the primary considerations.”
But energy efficiency experts say that technical fixes could eliminate or minimize the waiting time and inconvenience, some at little expense. Low-energy European systems reboot from deep sleep in one to two minutes.
Alan Meier, a scientist at Lawrence Berkeley National Laboratory, said of the industry in the United States, “I don’t want to use the word ‘lazy,’ but they have had different priorities, and saving energy is not one of them.”
The Environmental Protection Agency has established Energy Star standards for set-top boxes and has plans to tighten them significantly by 2013, said Ann Bailey, director of Energy Star product labeling, in an e-mail. The voluntary seal indicates products that use energy efficiently. But today, there are many boxes on the list of products that meet the Energy Star standard that do not offer an automatic standby or sleep mode.
“If you hit the on/off button it only dims the clock, it doesn’t significantly reduce power use,” said Noah Horowitz, senior scientist at the natural resources council.
Energy efficiency is a function of hardware, software, the cable network and how a customer uses the service, said Robert Turner, an engineer at Pace, which makes set-top boxes that can operate using less power while not in active use.
Sometimes energy efficiency can be vastly improved by remotely adjusting software over a cable, Mr. Turner said. In this way, Pace reduced the energy consumption of some of its older boxes by half.
Cable boxes are not designed to be turned completely off, and even when in deep sleep mode, it takes time to reconnect and “talk” with their cable or satellite network, though that time is highly variable depending on the technology.
Mr. Wilson said he routinely unplugged his set-top boxes at night and waited only 45 seconds for television in the morning. But Dr. Meier said that when he tried to power down his home system at night, it took “hours” to reboot because the provider “downloaded the programming guide in a very inefficient way.”
Cable providers and box manufacturers like Cisco Systems, Samsung and Motorola currently do not feel consumer pressure to improve box efficiency. Customers are generally unaware of the problem — they do not know to blame the unobtrusive little device for the rise in their electricity bills, and do not choose their boxes anyway.
Those devices may cause an increase of as little as a few dollars a month or well over $10 for a home with many devices. In Europe, electricity rates are often double those in the United States, providing greater financial motivation to conserve.
Cisco Systems, one of the largest makers of set-top boxes, said in an e-mail that they would offer some new models this year that would cut consumption by 25 percent “through reduced power used in ‘on’ and standby states.” There will be no deep sleep or fully “off” setting.
But Cisco said that taking advantage of the potential energy savings for a box would also depend on “how it is operated by the service provider.” Cable and satellite providers will have to decide whether the boxes can automatically go to standby, for example, and whether customers will be able to adjust their own settings. Currently, providers often do system maintenance and download information at night over the cable, so an ever-at-the ready cable box is more convenient for them.
Cable companies can become Energy Star “partners” if they agree to install or upgrade boxes so that 25 percent to 50 percent of the homes they serve have “energy star qualified” equipment. The E.P.A. merely encourages providers to use units that can automatically power down at least partly when not in use.
But as of Sept. 1, typical electricity consumption of Energy Star qualified products would drop to 97 kilowatt hours a year from an average of 138; and then by the middle of 2013, they must drop again to 29 kilowatt hours a year. Companies have fought the placement of the “Energy Star” seal on products and the new ambitious requirements, which may still be modified before enacted.
Mr. Wilson recalled that when he was on the California Energy Commission, he asked box makers why the hard drives were on all the time, using so much power. The answer: “Nobody asked us to use less.”
The biggest challenge in reducing energy use is maintaining the rapid response time now expected of home entertainment systems, Mr. Turner said. “People are used to the idea that computers take some time to boot up,” he said, “but they expect the TV to turn on instantly.” "

Micropointing is a miniature pointing device, designed for use in handheld devices such as smartphones, navigating systems, and notebook PCs features technology uniting exceptionally small size with unprecedented user friendly control.
Micropointing’s “fingertip control area” is only one square millimeter.
- Solves the challenge of added smart phone functionality while maintain ing small footprint, combined with superior usability and performance and an intuitive interface
- Eliminates need for small fingers in operating cell phones and other devices and delivers robust durability with no moving parts, helping to reduce replacement parts costs
- Offers improved functionality, high resolution, and exceptional sensitivity,
It is implemented in flash player 9.0.115 and some versions of Flash Media Server 3.
This technique is used by the Hulu desktop player.
Streamed content is encrypted by the Flash Media Server "on the fly", so that there is no need to encrypt the source file (a significant difference from Microsoft's DRM). For transmission ("streaming"), a special protocol is required: either RTMPE or RTMPS.
RTMPS uses SSL-encryption. In contrast, RTMPE is designed to be simpler than RTMPS, by removing the need to acquire an SSL Certificate. RTMPE uses Diffie-Hellman key exchange and HMACSHA256, generating a pair of RC4 keys.
One of which is then used to encrypt the stream from the server , while the other key is used to encrypt any data sent to the server. RTMPE caused less CPU-load than RTMPS on the Flash Media Server.
The Adobe RTMPE algorithm tries to provide end-to-end secrecy in exactly the same way that SSL provides end-to-end secrecy, but the algorithm is subject to man-in-the-middle attacks, provides no security, relies on publicly obtainable information and the algorithm itself to obfuscate the content, and uses no authentication of any kind.
Wikipedia: Protected Streaming
Whitepaper by Adobe
A usfull utility for working with these streams is rtmpdump.
It's a toolkit for RTMP streams. All forms of RTMP are supported, including rtmp://, rtmpt://, rtmpe://, rtmpte://, and rtmps://.
Here is one from http://www.stoppayingcablebills.com/
This is getting hard to ignore.
- Are these sites just pirated streams in flagrant disregard of copyright law?
- Are they just organizing links to other people who are breaking laws by streaming copyrighted content?
- Are they scams?
- Are they just a repackage of existing free streams?
I am not willing to actuallty give them my credit card and load this on any of my PC's.

Exit Final Cut "Pro" from the Pro Video Editing Biz.... FCPx is a failure, DOA in Hollywood, "iMovie Pro" for Barmitzva/Wedding cutters.... Ding Dong! The Witch is Dead! As a loyal AVID editor it's time for a tall ice cold glass of refreshing Schadenfreude....
From NYTimes: Professional Video Editors Weigh In on Final Cut Pro X
By David Pogue June 23, 2011, 3:40 pm
Complaint: You can’t share a project with other editors. In professional editing companies, editors routinely exchange projects. But in FCP X, “all of your project organization is now globally contained in the application rather than in your project file. You literally have to give that other editor your entire computer,” writes one blogger.
If the other editors already have the raw video files, you can hand over the project file. The other editors can inspect the Project Library; on its Info panel, they can click “Modify Event References” to reconnect the project to their own copies of the media files.
