Interactive TV Innovations for Winter Olympics

Informitv reports that digital viewers to BBC television are able to receive some 500 hours of programming, up to 15 hours a day, through a choice of up to four extra screens, offering live events and news round-ups. The multiscreen service is similar to that for the last Summer Olympics, and indeed the last Winter Olympics, supported by news, results, medal tables and a viewing planner.

Broadband users in the UK are also able to access five channels of simulcast coverage, together with on-demand highlights. Among other innovations is the use of digital video effects to enhance the BBC coverage by combining representations of time and space. SimulCam provides a composite picture of two participants apparently competing at the same time, demonstrating where time is won or lost and the different lines taken. StroMotion is used in skating and snowboarding coverage to show a composite series of frames to illustrate body position and technique.

The patented technologies are provided by Dartfish and automatically compensate for differences in camera angle between two recorded performances and detect the position of moving objects. The technology has been successfully used in a number of major world sporting events.

The Cloud Imperative for Telecom Operators

The telecom sector is undertaking an update of its IT infrastructure. As demand for data continues to soar with the proliferation of 5G and new apps, network operators can't rely on their legacy hardware and network architectures. The process of "Cloudification" offers a path to reduce costs, improve efficiency and scalability, plus meet increasingly ambitious infrastructure sustainability goals. According to the latest market study by Juniper Research, cloudification spending by telecom operators will see tremendous growth in the coming years, rising from $26.6 billion in 2024 to $64.9 billion by 2028 -- that's a 144 percent increase in just four years.

However, operators must insulate mission-critical traffic when reducing power, to guarantee quality of service for enterprises," said Alex Webb, research analyst at
