The new DVB-H standard allows broadcasting of audio/video content to mobile terminals. Such devices underlie severe restrictions concerning processing load and power consumption. The most computational intensive and therewith most power consuming part of such terminals is the decoding of the H.264/AVC video datastream. We present optimization strategies for software-based H.264/AVC video decoding as well as the architecture of an H.264/AVC decoding companion chip with specialized coprocessors, which targets the above mentioned restrictions (1). Index Terms--DVB-H, H.264/AVC, Decoder, SOC

In digital broadcasting, interlaced and progressive scanning pictures may be used. MPEG-2 can encode both scanning pictures independently. However, in handling both formats, format converter is required. We propose a new broadcasting system which makes scanning compatible. To realize this, a new coding method and pre/post-processing methods are discussed. New coding scheme is based on progressive scanning coding, and some improvement technologies are introduced. This coding also saves more than 30% bit-rate of MPEG-2 interlaced coding.

Asynchronous transfer mode (ATM) is often described as the future computer networking paradigm that will bring high-speed communications t the desktop. What is ATM? How is it different from today's […]

The Serial Real-time Communication System (SERCOS) is a 32-bit fiber-optic digital interface that outpaces any other industrial communications bus in speed and detailed design. It came from Europe and is foreseen to become a global standard for connecting digital controls and drives. There are over 70 SERCOS facilities in North America such as those of Boeing, Chrysler, Ford and General Motors. It is, contrary to popular belief, not expensive and rivals older analog interfaces in cost effectiveness., Faster and more highly defined than any other industrial communication bus, the fiber-optic SERCOS may have what it takes to become a world standard for linking digital controls and drives.

From specialized image-compression ICs to op amps, manufacturers have touted high-definition television (HDTV) as a potential application for products introduced within the last few years. This promotion occurred despite the [...]

Europe has emerged as the world leader in defining digital wireless telecommunications standards. The US lags behind Europe, as does Japan. Now IC vendors worldwide have to decide whether to [...]

A clear shift towards digital technology was noticed at the 1992 International Broadcast Convention at Amsterdam. Scandinavian broadcasters indicated that the domestic use of HDTV, using digital transmission, may be possible by the year 2,000. An improved definition PAL system using widescreens, may be ready by 1995 and this may ring the death knell for mac. Random access video, use of supercomputers for generating slow-motion pictures and recording standards for videos were some other topics which featured at the convention.

Gridlock on the airways blocks U.S. cellular growth In car-crazed Los Angeles, traffic-jammed commuters have embraced mobile cellular phones with the same passion once reserved for automobiles themselves. But the […]

Digital technology built into industrial controls and instrumentation devices greatly increase the amount of information available to plant operators while optimizing plant performance and automation. However, competition to set the standards is hampering development.

The impact of the MP3 on the sound recording industry is assessed, focusing on difficulties in managing and calculating profits from digitally downloaded music. Topics include establishing standards regarding digital downloading, the history of compact discs, and the economic advantages of marketing MP3s to teenagers on the Internet.

OLE and subsequently OLE2 and the whole COM/DCOM/OLE/ActiveX world has fine aspirations. But does it give the right tools? In the first of a two part feature we look at […]

IMAP promises better message management--for those who can cope with its complexity. Hang around an airport long enough, and you will see an ironic sight: Mobile workers frozen in their […]

One standard for digital wireless communication would have been ideal. But when you look at how telecommunications networks tend to evolve, one standard represents just that -- an ideal that [...]
