New techniques for storing and presenting video clips on home and mobile devices


Technical Research Centre of Finland, VTT is serving as an expert in a European project for developing processing methods for mobile videos. In the near future, consumers will be able to store videos taken by video camera and video phones to their personal digital archives, where they can search and browse them, share them with their friends and view them on their own devices. The videos are easy to find and view on a computer, mobile phone or handheld computer. The new methods promote the commercialisation of video services and business activity in the field and improve the competitiveness of Finnish companies.

Consumers like to store their video clips systematically and view them on various wired or wireless devices: computers, mobile phones and handheld computers. The various characteristics of mobile devices, limited transfer rates and screen sizes a major challenge to new methods of processing videos.

VTT is involved in the work of designing new video processing methods for videos and is in charge of the practical tests in video processing. With the methods under development the locations and dates of the videos are stored in a database, as is information on the image and sound content and technical aspects of the shots. Thus the stored videos are easy to browse utilising intelligent video retrieval methods. The video is adjusted according to the terminal device, when transferred e.g. to the camera phone. The adaptation makes video transfer quick and inexpensive, as small amount of image data is sufficient for image precision on a camera phone. The original shot with video camera precision contains an enormous amount of image data.

During the upcoming summer, VTT and its partners will be testing novel European methods to store, retrieve, compress, transfer and present videos on a camera telephone or a computer. After the summer the methods will be integrated into single system. In the future consumers will be able to store videos into their own digital archives from which they can be viewed by their friends, family members and the consumers themselves on their own respective computers. Commercialisation of the new methods will take 3 to 5 years.

The R & D work is funded by VTT, Solid Information Technology, Hantro Products Oy and Tekes. The work forms a considerable part of an extensive Eureka project led by Bosch, and involving four European countries and 14 participating parties, among them Philips.

Solid Information Technology is developing distributed database technologies. According to Jorma Palo, the company’s Technology Manager, the development work for processing mobile videos has progressed to the point of exploring the commercial prospects of the most recent digital media. In the future the amounts of video data to be stored will be quite extensive, and consumers want to see their videos fast. The results of the development work will enable the development of convenient methods for the video products of the future. With this project the Finns can also make a significant contribution to the European standardisation work.

Im Focus: New 3-D wiring technique brings scalable quantum computers closer to reality

Researchers from the Institute for Quantum Computing (IQC) at the University of Waterloo led the development of a new extensible wiring technique capable of controlling superconducting quantum bits, representing a significant step towards to the realization of a scalable quantum computer.

"The quantum socket is a wiring method that uses three-dimensional wires based on spring-loaded pins to address individual qubits," said Jeremy Béjanin, a PhD...

Im Focus: Scientists develop a semiconductor nanocomposite material that moves in response to light

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
