    4SeTV Streaming Device Brings Four-in-One Viewing Experience to Big Screen TVs, Tablets and Smartphones

    4SeTV

    A new TV streaming device from 4SeTV lets you watch any four live television shows at once on a tablet, smartphone or TV. Alternatively, up to four people can view an individual live show of their choice on four different devices, at the same time.

    Built on patent pending technology, 4SeTV uses over-the-air broadcasting and streams the HD content you want to see to your connected devices in your home network. It is said to be the first-ever device that lets you select and watch four channels on the same screen.

    4SeTV hooks up to your HDTV antenna and connects to your router with an Ethernet cable. From there, simply switch the box on and go, at the push of a button.

    How it works:

    • Content is broadcast (i.e. free HDTV content over-the-air, clear QAM)
    • It is captured by an antenna and relayed to the 4SeTV device
    • Broadcast content is captured by the 4SeTV device
    • 4SeTV streams the content to connected devices in your home network (smartphones, tablets and TVs)

    4SeTV is now at the production unit stage and conducted live demonstrations of its device at the Showstoppers media event held yesterday at the NAB show in Las Vegas.

    4SeTV is available for pre-order on Kickstarter and is priced at $99 for early adopters. The first units are slated to ship in August.

  • Cell Phone Antenna Troubles? Radio Frequency MEMS Come to the Rescue

    Help may be on the way for iPhone 4 users frustrated by dropped calls with the arrival of Radio Frequency Microelectromechanical Systems (RF MEMS), semiconductors that can improve the performance of antennas in cell phones, according to the market research firm iSuppli.

    Long plagued by technological hurdles and other disappointing setbacks, RF MEMS are finally ready for the big time, with revenue projected to double in 2010 and more than triple in 2011, as the analysts say.

    From slightly less than $4 million in 2006, global RF MEMS revenue is anticipated to climb to $8.1 million this year—and then surge to $27.9 million in 2011, according to iSuppli. By 2014, revenue will reach a whopping $223.2 million—a far cry from the industry’s extremely modest beginnings.

    “More than 50 percent of cell phones shipped in 2014 will feature some form of front-end-module tuning using RF MEMS technology,” said Jérémie Bouchaud, principal analyst for MEMS and sensors at iSuppli.

    “The implementation of RF MEMS switches and varactors in mobile phones could help boost the performance of smart phones like the iPhone 4, which made news headlines recently because of a problematic antenna that resulted in dropped signal strength. RF MEMS are also ideal for impedance matching of the Power Amplifier,” he said.

    Although other technologies will address antenna issues, including SoS FETs and BST varactors, MEMS deliver the best performance in terms of insertion loss.

    According to iSuppli analysts, RF MEMS switches have been used in small volumes in instrumentation applications because of their small form factor and excellent RF performance. However, despite initial promise, they failed to take off on a large scale because of myriad commercialization and technological obstacles. All that is about to change as RF MEMS technology begins to realize its potential because of strong product offerings from a number of major suppliers.

    The report finds that Seven firms are sampling RF MEMS products.

    California-based WiSpry Inc. and Japan’s TDK-Epcos are offering RF MEMS for high-volume cell phone applications. On another front, U.S. firms Analog Devices Inc., Radant Technologies Inc. and XCOM Wireless Inc.—in cooperation with relay manufacturer Teledyne Technologies Inc.—as well as Japanese supplier Omron Corp. are targeting high-end applications for testing and instrumentation such as ATE and RF test. U.S. startups Radant MEMS and MEMtronics focus on defense applications.

    "In particular, interest is growing among mobile handset manufacturers on how RF MEMS can be used for the front-end tuning of cell phones to improve antenna performance, given the advent of new wireless standards like LTE for 4G technology. WiSpry—which has garnered several design wins for its MEMS varactors—is expected to commence volume production by the fourth quarter this year," said Bouchaud.

  • Sagem Embeds GPS Receiver into SIM Cards


    Smartcard vendor, Sagem Orga has formed a partnership with BlueSky Positioning to integrate its A-GPS positioning technology onto conventional SIM cards.

    A GPS receiver and proprietary antenna are integrated into the SIM card, which the companies say then enables mobile operators to deploy applications without the need for software or hardware changes.

    The A-GPS provides accurate positioning information for the phone to emergency services in case of an emergency call as required by E112 and E911 legislation in the EU and the US respectively.

    It can also support generic location-based services such as navigation, "find a place or person" services, location-aware games, and many more.

    Navigations solutions are increasingly availabile on smartphones and mobile phones.

    Sagem Orga and BlueSky Positioning say the two broad technical approaches that can deliver the accuracy required for these services demand either significant investment in networks by the mobile operator or the purchase of new handsets by the end user.

    In a statement, they said the A-GPS SIM would allow mobile operators to significantly increase the cost effectiveness of their services and size of their marketing target when launching new LBS.

    François Blanchard, global account marketing manager at Sagem Orga, said the technology would help the mobile industry overcome the "key stumbling block" to the success of location-based services – affordable, accurate positioning technology.

    "The SIM is entering a new era where it can now be considered as a real service platform and a valuable device; the A-GPS enabled SIM card will reshape the way SIM card are perceived by MNOs and end-users," he said.

  • Mobile TV To Become Standard Feature of Smartphones

    Mobile TV has really only achieved great popularity in nations such as Japan and Korea.

    But the market is expected to expand rapidly over the next few years, spurred on by the smartphone which is driving improvements in screen quality, microchips and antennas.

    Smartphone.biz-news.com spoke to David Srodzinski, chief executive of fledgling semiconductor firm Elonics, about his expectations for the future of mobile TV.

    Mobile TV will soon become as accepted a feature of mobile handsets as the camera.

    That is the prediction of David Srodzinski, founder and chief executive of Elonics, a semiconductor company that has designed a silicon radio frequency (RF) tuner used to convert signals into sound and pictures.

    “We do see mobile TV as going to take off just like the camera phone has taken off,” he said.

    “It’s not something you will use all the time, but it’s a part of the phone that will be such a ‘nice to have’ feature that all phones will simply have to have them.”

    David Srodzinski CEO Elonics

    Based in Livingston, Scotland, Elonics recently announced that David Milne, the founder and former chief executive of chip maker Wolfson Microelectronics, was joining its board as non-executive chairman.

    Milne was credited with taking Wolfson from a university spinout to the FTSE 250 and the company made its name as a key supplier of microchips to the iPod.

    Founded in 2003, Elonics has developed RF architecture called DigitalTune that is the foundation for a family of re-configurable CMOS RF front end products.

    Its E4000 device is designed for reception of all major world-wide fixed and handheld terrestrial digital multi-media broadcast standards within UHF to L-Band ranges (76MHz to 1.70GHz).

    It allows designers to implement front ends capable of cost effectively supporting multiple TV and radio broadcast standards and enabling smaller, lighter, cheaper and lower power consumer electronics.

    Elonics has finished market sampling its products and is about to begin mass-production.

    Srodzinski said the immediate focus for the broadcast receiver technology was the traditional TV market, ranging from digital TVs, set-top boxes and PC TVs to multi-media devices.

    But he believed the biggest opportunities lay in the mobile TV market, with analysts forecasting sales of mobile TV enabled handsets rising to 100 millionin 2010.

    “All future potential growth is coming from the cell phone side of the market,” he said. “Smartphones are increasingly a sizeable part of that market.”

    Screen size and quality a key factor influencing the adoption of mobile TV on cell phones

    Srodzinski said that with QVGA screens appearing on increasing numbers of handsets, a barrier to mobile TV was being removed.

    He said that prior to the introduction of QVGA screens, adding mobile TV to a cell phone meant additional costs for the screen, the graphic processors and mobile TV chip set.

    “With the advent of QVGA offerings, such as on the new HTC phones and the iPhone, which have them as standard, the cost add of mobile TV is minimal now,” he said.

    For the screens alone, Srodzinski estimated that the cost add had dropped by a tenth, from USD $50 to $5.
    “All that has to be added now is the mobile TV chip set,” he said.

    But if cost and technological issues were no longer an impediment to widespread uptake of mobile TV, what about users’ appetite for the service?

    Srodzinski expected mobile TV to be something people would use once or twice a week for five to 10 minutes, most probably as a free-to-view service.

    “That user experience will be such a good feature and such a compelling reason, that people will want mobile TV on their cell phones in a similar way to how they want to have camera phones too,” he said.

    “We believe that if mobile TV works and takes off in that way, it will be a major opportunity that will grow out of the smartphone and into middle layer cell phones.”

    The great success of mobile TV in Japan and Korea, where penetration rates now reach 40 per cent, owes a great deal to government intervention promoting the services, according to Srodzinski.

    He said this had created revenue opportunities and lifted technological barriers to entry.

    “What’s holding back other parts of the world has more to do with the infrastructure roll-out and the cost of doing that,” he said. “That and the lack of clear government support.”

    However, Srodzinski insisted that the growth of mobile TV in territories outwith Japan and Korea would accelerate as more people experienced it and saw the quality of the services and content.

    “I think other regions will catch on,” he said. “This is not a technological push situation – it has to be a consumer-led requirement., especially if it’s free-to-air that takes off.”

    While content may be free, any explosion in mobile TV will also have to offer opportunities for revenue to the industry.
    As Srodzinski said: “The question has to be: who makes any money out of it? There’s no particular economic benefit to operators.”

    Undoubtedly an answer to that conundrum will be found, but will mobile TV really take off?
