We present a framework for assessing the quality of, and determining the efficiency of foveated and compressed images and video streams. We develop unique algorithms for assessing the quality of foveated image/video data. By interpreting foveation as a coordinate transformation, we analyze the increase in compression efficiency that is afforded ...

Frame erasure concealment using sinusoidal analysis-synthesis and its application to MDCT-based codecs

  • Aguilar G.
  • Juin-Hwey Chen
  • Parikh V.

This paper presents a frame erasure concealment algorithm based on sinusoidal analysis-synthesis and its application to MDCT-based codecs. When a frame is lost, sinusoidal analysis of the previously decoded and buffered signal is performed. The analysis gives a set of sinusoids, which are used to synthesize the waveform corresponding to ...

On fundamental issues in IP over WDM multicast

  • Chunming Qiao
  • Wei J.
  • Xijun Zhang

As WDM technology matures, IP over WDM multicast will become a challenging new topic. Supporting multicast at the WDM layer provides additional advantages, but also raises many new issues that do not exist in IP multicast. For example, the limitation on the light splitting capability of switches is one major ...

These developments are based on ultra high speed chips and on ...

Prevention of plasma induced damage on thin gate oxide of HDP oxide deposition, metal etch, Ar preclean processing in BEOL sub-half micron CMOS processing

  • Ackaert J.
  • Coppens P.
  • Creusen M.
  • De Backer E.

In this paper a comparison is made of several PID measurement techniques. A novel mechanism of plasma induced damage (PID) by high density plasma (HDP) inter metal dielectric (IMD) deposition is proposed. Results of a design of experiment (DOE) on Ar preclean minimizing PID are presented. For metal etch, HDP ...

Catering for electromagnetic compatibility requirements in the project plans of products

  • Venter F.

This paper addresses the main issues that one needs to take into account when drafting project plans for new products, where EMC requirements have to be incorporated. It is also shown why these guidelines must be implemented as early in the product development cycle as possible. Some practical problems with ...

Silicon radio integration: architectures and technology: from cartesian zero IF receive & transmit to polar zero I and Q, from silicon bipolar to bulk and SOI CMOS

  • Sevenhans J.

During the nineties we have witnessed a string of advances in Silicon RF integration: from the introduction of the first integrated Si bipolar radios for GSM and DECT in the late eighties to the full single chip integration capabilities today using SiGe BiCMOS technologies. Where RF design used to be ...
