TV Channel Distribution in Europe: Table of Contents
TV Channel Distribution in Europe: Table of Contents This report covers 238 international channels/networks across 152 major operators in 34 EMEA countries. From the total, 67 channels (28%) transmit in high definition (HD). The report shows the reader which international channels are carried by which operator – and which tier or package the channel appears on. The report allows for easy comparison between operators, revealing the gaps and showing the different tiers on different operators that a channel appears on. Published in September 2012, this 168-page electronically-delivered report comes in two parts: A 128-page PDF giving an executive summary, comparison tables and country-by-country detail. A 40-page excel workbook allowing you to manipulate the data between countries and by channel. Countries and operators covered: Country Operator Albania Digitalb DTT; Digitalb Satellite; Tring TV DTT; Tring TV Satellite Austria A1/Telekom Austria; Austriasat; Liwest; Salzburg; UPC; Sky Belgium Belgacom; Numericable; Telenet; VOO; Telesat; TV Vlaanderen Bulgaria Blizoo; Bulsatcom; Satellite BG; Vivacom Croatia Bnet Cable; Bnet Satellite Total TV; Digi TV; Max TV/T-HT Czech Rep CS Link; Digi TV; freeSAT (formerly UPC Direct); O2; Skylink; UPC Cable Denmark Boxer; Canal Digital; Stofa; TDC; Viasat; You See Estonia Elion nutitv; Starman; ZUUMtv; Viasat Finland Canal Digital; DNA Welho; Elisa; Plus TV; Sonera; Viasat Satellite France Bouygues Telecom; CanalSat; Numericable; Orange DSL & fiber; SFR; TNT Sat Germany Deutsche Telekom; HD+; Kabel -
IBM Research Report Proceedings of the IBM Phd Student Symposium at ICSOC 2006
RC24118 (W0611-165) November 28, 2006 Computer Science IBM Research Report Proceedings of the IBM PhD Student Symposium at ICSOC 2006 Ed. by: Andreas Hanemann (Leibniz Supercomputing Center, Germany) Benedikt Kratz (Tilburg University, The Netherlands) Nirmal Mukhi (IBM Research, USA) Tudor Dumitras (Carnegie Mellon University, USA) Research Division Almaden - Austin - Beijing - Haifa - India - T. J. Watson - Tokyo - Zurich Preface Service-Oriented Computing (SoC) is a dynamic new field of research, creating a paradigm shift in the way software applications are designed and delivered. SoC technologies, through the use of open middleware standards, enable collab- oration across organizational boundaries and are transforming the information- technology landscape. SoC builds on ideas and experiences from many different fields to produce the novel research needed to drive this paradigm shift. The IBM PhD Student Symposium at ICSOC provides a forum where doc- toral students conducting research in SoC can present their on-going dissertation work and receive feedback from a group of well-known experts. Each presentation is organized as a mock thesis-defense, with a committee of 4 mentors providing extensive feedback and advice for completing a successful PhD thesis. This for- mat is similar to the one adopted by the doctoral symposia associated with ICSE, OOPSLA, ECOOP, Middleware and ISWC. The closing session of the symposium is a panel discussion where the roles are reversed, and the mentors answer the students’ questions about research careers in industry and academia. The symposium agenda also contains a keynote address on writing a good PhD dissertation, delivered by Dr. Priya Narasimhan, Assistant Professor at Carnegie Mellon University and member of the ACM Doctoral Dissertation Committee. -

The naïve observer may conclude that such variety of database replication from both academia and industry. However, replication systems indicates a solved problem; the reality, academic groups often attack replication problems in isolation, however, is the exact opposite. Replication still falls short of overlooking the need for completeness in their solutions, while customer expectations, which explains the continued interest in developing new approaches, resulting in a dazzling variety of commercial teams take a holistic approach that often misses offerings. opportunities for fundamental innovation. This has created over time a gap between academic research and industrial practice. Even the “simple” cases are challenging at large scale. We deployed a replication system for a large travel ticket brokering This paper aims to characterize the gap along three axes: system at a Fortune-500 company faced with a workload where performance, availability, and administration.

Operating System Vs. Middleware
What is Middleware? Application Application Middleware Middleware Operating System Operating System Software that functions as a conversion or translation layer. • It is also a consolidator and integrator. – Custom-programmed middleware solutions have been developed for decades to enable one application to communicate with another that either runs on a different platform or comes from a different vendor or both. • Today, there is a diverse group of products that offer packaged middleware solutions.
