A Bangalore based startup, Apptarix has recently launched TeleTango, a social TV network for Indian television.

TeleTango converts TV viewing from a one-way media to multi-way interaction channel.  With TeleTango, TV viewers can check what their friends are watching or what’s hot on TV, join friends in a show for a group chat, post opinion in Facebook and Twitter and interact with the program through opinion polls, voting and commentary in sync with the program. TeleTango also provides a platform for the TV broadcasters to host and feed the complementary digital content such as trivia, gossip, exclusive picture, opinion polls and voting in sync with live TV program.

A team of researchers led by Indian-origin Shyam Gollakota from the University of Washington has devised a way for wireless devices to communicate without the need for batteries.

Known as Ambient Backscatter, the technology uses wireless signals like television and cell phone transmissions surrounding us. According to reports, the wireless devices communicate by reflecting these signals and exchanging information through them. Gollakota’s team had designed battery-less wireless devices with attached antennas, which could detect, harness and then reflect television signals. These signals were then picked up by similar devices. The devices apparently use the wireless signals as both, a source of power and a medium for communication.

This technology could turn out to be highly useful, as it would eliminate the need for a power source in wireless or network related devices. This would also lead to less requirement of human attention towards such devices. Read more in this report by EFYTimes.

Indian-origin researchers from the University of Washington (UW) have developed a new gesture-recognition technology called WiSee that leverages Wi-Fi signals to detect specific movements, without needing sensors on the human body or cameras.

Reasearchers have shown that by using an adapted Wi-Fi router and a few wireless devices in the living room, users could control their electronics and household appliances from any room in the home with a simple gesture. Read more

Two scientists, Professor Siddharth Ramachandran of Boston University and Alan Willner of University of Southern California, have devised a new fibre optic technology that promises to increase bandwidth dramatically, easing Internet congestion and video streaming.

The technology centers on donut-shaped laser light beams called optical vortices, in which the light twists like a tornado as it moves along the beam path, rather than in a straight line. Widely studied in molecular biology, atomic physics and quantum optics, optical vortices (also known as orbital angular momentum, or OAM, beams) were thought to be unstable in fibre, until the duo recently designed an optical fibre that can propagate them.

In the paper in journal Science, he and Willner demonstrated the stability of the beams in optical fibre and also their potential to boost Internet bandwidth.

Traditionally, bandwidth has been enhanced by increasing the number of colours, or wavelengths of data-carrying laser signals – essentially streams of 1s and 0s – sent down on an optical fibre, where the signals are processed according to colour.

Prof. Ramachandran’s and Willner’s approach combines strategies, packing several colours into each mode, and using multiple modes. In their experiments, they created an OAM fibre with four modes (an optical fibre typically has two), and showed that for each OAM mode, they could send data through a one-kilometre fibre in 10 different colours, resulting in a transmission capacity of 1.6 terabits per second.

A lot of businesses today offer services that require customers to sign up online, and as the customer base grows, managing their billing becomes a tougher task for enterprises.

Now businesses can focus on providing products or services without the hassle of managing their online subscriptions. Chennai-based startup, Chargebee, has developed software tools targeted at small and medium businesses to manage recurring subscription payments. The new software is off-the-shelf plug-and-play billing tool that’s delivered on the cloud. You can connect with ChargeBee via API (application programming interface) if you are technically inclined or use PCI-compliant hosted payment pages to collect payments, and go live in a matter of minutes.

ChargeBee says it provides a robust and flexible billing system to enable enterpises run special promotions as well as to bill accurately and respond faster for billing queries. It also helps collect payments online. Read more in a detailed interview by Srinivas Kulkarni.

Besides sharing images of characters from their favourite shows, or photographs of places, now here’s a new platform for users of social media to share their photographs and opinions on clothing, accessories and food.

A Bangalore-based company, founded by Arjun Zacharia, Praveen Rajaretnam, Soumen Sarkar and Ankit Sabharwal, former employees of McAfee, has launched Wooplr as a social discovery platform for users who wish to share their images of finds and bargains from local stores.

Wooplr is about helping people discover products from brick-and-mortar stores or flea-market brands — those we might not ever hear of if someone didn’t tell us about them. Currently, there is no platform where Indian shoppers can find genuine shopping/eating recommendations with visuals and share their shopping finds or find out what their friends are buying and from where, says Rajaretnam.

When a Wooplr user sees an attractive piece of clothing or a stylish accessory, s/he tags a photo of it on the platform, with a note on where the item was purchased and for how much. This allows those with similar tastes to take notes for their next shopping trip. Read more in this news report by Shrabonti Bagchi on why do users need something like this when there already are so many social media platforms for sharing visual content.

Faculty and students at the Indian Institute of Technology Rajasthan (IIT-R), in association with National Instruments India, have developed the intellectual property (IP) for a digital radio mondiale (DRM)-based transmitter. The broadcasting system, developed by the international DRM consortium, has been proposed as a high-quality digital replacement for analogous broadcasting in AM and FM/VHF bands. It offers listeners a wide range of programming, with enhanced audio performance and multimedia services such as broadcasting text, slideshows of still and animated images, electronic newspapers, and weather and traffic information. The technology will make it possible for rural and remote parts of India to access both local and international transmissions.

National Instruments India and IIT-R have signed a Memorandum of Understanding (MoU) to record their intention of starting and running a Center of Excellence on Communication and Physical Layer Technologies at IIT-R. As part of the MoU, a National Instruments Advanced Communication Laboratory was established at IIT-R in November 2010 to enable research and project development in the areas of wireless communication and physical layer technologies, and undertake research projects and industrial consultancy. Software and hardware subsystems provided in the lab enable rapid prototyping, and development of embedded systems for various applications.

Prem Kalra, professor and director, IIT-R, said: “The Indian Institute of Technology Rajasthan represents a unique culture of engineering and science education and research. Through Centres of Excellence with their innovative curriculum design, interdisciplinary research and thought leadership, IIT-R aims to create leaders who are entrepreneurial and well-rounded. Our aim is to make the fruits of technology available to the “last person”, the poorest people of our country. Our partnership with National Instruments India emphasizes our long-held belief that a synergistic partnership between industry and academia can make this happen.”

DRM, which has a lossless transmission range of about 100 kilometers, allows flexibility for the system to optimize according to the local environment conditions through an exchange in bit rate capacity, spectrum occupancy, and robustness mode and transmission power. (Click here to view DRM transmitter.) IIT-R students are currently engaged in building an embedded version of such a system, for potential application in broadcasting special services such as weather forecast, national news, important announcements, educational presentations etc. for rural India.
