Struggling online video startup Joost, begun with much fanfare in 2007 by the same people behind Skype and Kazaa, is restructuring its business after discovering that it can’t survive on advertising to fund its operations.

The chief executive, Mike Volpi, has stepped down but will remain as chairman.

The London-based company said it will shift its focus from being an online video site for consumers supported by advertising - similar to Google Inc.’s YouTube. Instead, it will help businesses manage their videos on the Internet as they build brands.

Its target market will be media companies such as cable and satellite TV providers, broadcasters and video aggregators.

“In these tough economic times, it’s been increasingly challenging to operate as an independent, ad-supported online video platform,” Volpi said in a statement.

Joost was co-founded by Janus Friis and Niklas Zennstrom, the same people behind Internet phone service Skype and the file-sharing site Kazaa. It has minority investments from Viacom Inc. and CBS Corp.

It started as a peer-to-peer sharing site but wasn’t successful, then switched to online video. But Joost has suffered from poor traffic and had trouble making money.

Joost, which also has offices in New York, is closing its Leiden office in the Netherlands. The company declined to say how many people it’s laying off.

Television host Jay Leno has won control of a Web address using the name of his new show.

The U.N.’s World Intellectual Property Organization says current owner Guadalupe Zambrano of Katy, Texas, will have to transfer the domain name - thejaylenoshow.com - to the comedian.

The agency says Zambrano failed to demonstrate he had a legitimate reason for registering the address five years ago while Leno was still hosting “The Tonight Show.”

Zambrano used the site to redirect Web surfers to his real estate business.

The Associated Press is digitizing and has begun to release a “treasure trove” of historical film footage from the 1960s and ’70s that had been sitting in Gen. Dwight D. Eisenhower’s former World War II headquarters in London.

The archive includes color film recordings of a young Yasser Arafat, Libyan leader Moammar Gadhafi immediately after taking power, Richard Nixon with Romanian dictator Nicolae Ceausescu, Fidel Castro meeting Latin American and Eastern European leaders, as well as a young Saddam Hussein in Paris.

“The range and quality of what we’re finding in this lost archive is breathtaking and it’s incredibly exciting to be unearthing new history in this way,” said Alwyn Lindsey, AP’s director of international archives.

The footage had been sitting for decades in the Central London bunker, from which Eisenhower directed the D-Day landings.

Although the films have been well-preserved, the text that accompanied them has been scattered across the United States and the United Kingdom, the AP said. That text catalog was key to identifying the footage held in each of the 20,000 film cans.

AP’s footage business, AP Archive, brought in leading archival researchers to create a coherent online text database from the scattered paper records. The films are being cleaned, restored and transferred onto high-definition videotape for professional producers. They are also being digitized for viewing online.

Global Gaming Factory X AB, which operates Internet cafes and provides software, said Tuesday that it had agreed to buy Pirate Bay for 60 million Swedish crowns ($7.7 million).

The website made world headlines in April when the three Swedish founders and a financial backer were each sentenced to one year in jail and ordered to pay a combined $3.6 million in damages for breaching copyright law with the free downloading site, which was one of the biggest sites of its kind on the Internet.

Swedish News Agency TT cited one of the founders, Peter Sunde, as saying that the money would not go directly to him or any of the others sentenced in April.

Sunde told TT that the money would be placed in a company outside Swedish borders and it would be used for Internet projects other than downloading sites.

A team led by Yale University researchers has created the first rudimentary solid-state quantum processor, taking another step toward the ultimate dream of building a quantum computer.

They also used the two-qubit superconducting chip to successfully run elementary algorithms, such as a simple search, demonstrating quantum information processing with a solid-state device for the first time. Their findings will appear in Nature’s advanced online publication June 28.

“Our processor can perform only a few very simple quantum tasks, which have been demonstrated before with single nuclei, atoms and photons,” said Robert Schoelkopf, the William A. Norton Professor of Applied Physics & Physics at Yale. “But this is the first time they’ve been possible in an all-electronic device that looks and feels much more like a regular microprocessor.”

Toyota (NYSE: TM) researchers in Japan have built a brain/machine interface (BMI) that has been demonstrated to control a wheelchair using a person’s thoughts.

The system enables a person to make a wheelchair turn left or right to move forward simply by thinking the commands. The response time is in 125 milliseconds. One millisecond is equal to 1/1000 of a second.

The BMI was developed at the BSI-Toyota Collaboration Center (BTCC), a 2-year-old research center established by Japan’s government research unit RIKEN and Toyota Motor, Toyota Central R&D Labs, and Genesis Research Institute. Japan has focused on the control of devices through brain waves as a way to deal with the projected shortage of healthcare workers to tend to Japan’s large aging population.

The BTCC’s system uses several sensors placed over the areas of the brain that control motion to measure electrical activity in the region. The electical impulses triggered by the rider thinking of turning or moving the wheelchair are picked up and analyzed by an onboard laptop that passes the commands on to the wheelchair.

The system has an emergency stop that can be activated by the user puffing his cheeks.

Cable TV operators won a key legal battle against Hollywood studios and television networks on Monday as the Supreme Court declined to block a new digital video recording system that could make it even easier for viewers to bypass commercials.

The justices declined to hear arguments on whether Cablevision Systems Corp.’s remote-storage DVR system would violate copyright laws. That allows the Bethpage, N.Y.-based company to proceed with plans to start deploying the technology this summer.

With remote storage, TV shows are kept on the cable operator’s servers instead of the DVR inside the customer’s home, as systems offered by TiVo Inc. and cable operators currently do.

The distinction is important because a remote system essentially transforms every digital set-top box in the home into a DVR, allowing customers to sign up instantly, without the need to pick up a DVR from the nearest cable office or wait for a technician to visit.

Movie studios, TV networks and cable TV channels had argued that the service is more akin to video-on-demand, for which they negotiate licensing fees with cable providers.

They claimed a remote-storage DVR service amounts to an unauthorized rebroadcast of their programs.

In a statement, the Copyright Alliance, whose members include Hollywood studios and television broadcasters, called the Supreme Court action “unfortunate and potentially harmful to creators and creative enterprises across the spectrum of copyright industries.”

Cablevision argued its service was permissible because the control of the recording and playback was in the hands of the consumer.

Industry experts say the new technology could put digital recording service in nearly half of all American homes, about twice the current number.

Comcast Corp. will become the first major cable TV operator to roll out wireless broadband outside of Wi-Fi hotspots as it launches the service in Portland, Ore., on Tuesday, with at least three other cities to follow this year.

Comcast will offer speeds of up to 4 Megabits per second, faster than any other comparable, non-Wi-Fi service currently being marketed. The service is for use with laptops, but not other mobile devices.

Comcast’s wireless broadband, which lets users surf the Web on the go with their computers, pits it squarely against the mobile data offerings of phone companies.

But the cable operator is coming out first with the market’s fastest wireless broadband, using WiMax technology. Phone companies have lined up behind a competing technology called LTE, with Verizon Communications Inc. planning to deploy it next year.

The judge in the Pirate Bay case, Tomas Norström, was not biased. That’s the decision of the Swedish High Court of Justice, which investigated accusations made by the four defendants in the high-profile file-sharing case.

The accusations were based on Norström’s membership in organizations such as the Swedish Copyright Association, which counts among its members lawyers who represented the plaintiffs during The Pirate Bay trial.

The court ascertained that such memberships do demonstrate a commitment to intellectual property issues, which could be considered by some to be in the interest of the plaintiffs. But it also pointed out that rights-holders’ rights are protected by the Constitution, and so cannot be considered a conflict of interest if a judge endorses the principles behind copyright laws.

The court did say it would have been appropriate for the judge to disclose these memberships, which could have led to an investigation of potential conflicts of interest at an earlier stage in the process.

But as a whole, none of these circumstances are enough for sending the case back to the district court, according to the High Court, which now will look at the main appeal of the verdict.

The long-running $1,000,000 competition to improve on the Netflix Cinematch recommendation system by 10% (in terms of the RMSE) may have finally been won. Recent results show a 10.05% improvement from the team called BellKor’s Pragmatic Chaos, a merger between some of the teams who were getting close to the contest’s goal.

Microsoft is reportedly considering offering Windows 7 on USB thumb drives to allow netbook owners to upgrade their machines.

Windows has, until now, only been distributed on DVDs or via download. However, netbooks don’t come with optical drives and downloading an operating system is a frankly painful experience.

The Windows 7 ISO weighs in at 2.3GB, which would take several hours to download on an average broadband connection and potentially do serious damage to a customer’s broadband data cap.

Consequently, the company is exploring alternative means of distributing the OS, including USB flash drives

Software developed by a Canadian lab to circumvent online censorship has been downloaded by more than 18,000 Iranians in the last 10 days, says its developer Rafal Rohozinski.

A thirst for online freedom in Iran, as well as in China, Myanmar and other authoritarian hotspots, has led to a sudden proliferation of all technologies designed to overcome curbs on news and social networking Internet sites.

“This speaks to the hunger for access to information when it’s being denied,” Rohozinski told AFP.

Iranians angered by the results of the country’s presidential election that returned hardline incumbent President Mahmoud Ahmadinejad to power have been using social and media sites such as Facebook, Flickr and Twitter to communicate and organize.

They have also been posting videos of violent post-election protests and clashes to video-sharing sites such as YouTube.
