Introduction:
Notes on Entering the “Connected on Demand” Era

The count down to the 2012 Olympic Games has now begun and these games will offer live online streamed content, where and when we want it. Our expectations of sports coverage have undoubtedly come a long way since sports fans huddled around TV sets in Berlin and Leipzig to see the 1936 Olympic Games broadcast live.

You only have to look back a few years to see evidence of how far technology has come; less then five years ago a set-top box or TV just received a broadcast program, so it was a case of settling down at the allocated time to take in your favorite show or sporting event. Today High Definition (HD) set-top box (STB) or high end DTV have integrated storage devices for recording your favorite show, pausing live TV or fast forwarding through commercials. The set-top box is also connected to a home network and the internet, enabling families and friends to share content and services via a variety of devices in the home.

ARM and Qt Development Frameworks “Staying Tuned”

By Dilip Kenchammana, Product Line Manager, Nokia Qt Development Frameworks
Qt is a cross platform C++ application framework that today is available on several embedded and mobile platforms as well as devices, which use Linux, Mac OS X and Windows operating environments. The inherent cross platform nature of the Qt technology proposition is playing a crucial role now, as home and mobile electronic devices constantly spawn new form factors. While the physical ‘shape of the box’ may be changing, people demand a consistent user experience that they know and recognize as they spend more time using increasingly sophisticated pieces of equipment.

Audio for Next-Generation Broadcast Services: The Dolby MS10 Multistream Decoder Solution

Over the last 18 months, various European industry groups such as DVB, EBU, EICTA, and a number of national HDTV specification forums have considered the selection of audio coding systems for next-generation broadcast applications, including HDTV broadcasts, using MPEG-4 video. In general, these considerations have highlighted two standardized audio coding systems as particularly suited to next-generation transmissions: Dolby Digital Plus (also known as E-AC-3) and Dolby Pulse (Dolby’s implementation of aacPlus or HE AAC). The EBU Project Group D/MAE, for example, concluded that the two coding formats are the best candidates for broadcasting HDTV audio services via satellite, cable, terrestrial, and IPTV networks.

Developing Power-Efficient Software Systems on ARM Platforms

By Chris Shore, ARM Training Manager

(Pages 48-53)

Given the emphasis on battery life for portable devices, it would seem strange that there are very few software engineers who actually have energy reduction in their daily project accountabilities. I suspect that those who do give the subject some thought are likely to do it on a “commendation vs. court martial” basis. We are entering a period when this will have to change.

Linux, Nucleus... or Both

By Colin Walls, Mentor Graphics
(Page 56-59)

 

Until recently, operating system (OS) specification for embedded systems has been seen largely as an ‘either/or’ exercise. Similarly, OSs that have their foundations in the embedded market and those that have grown out of desktop computers have been seen as competing rather than complementary technologies.
