However, in order to effectively support multimedia as well as ordinary traffic through a WMN infrastructure, traffic control is generally needed as wireless communications, especially in mesh network configurations, can be affected by significant congestion and channel impairments problems. In this work we are focusing on performance assessment and enhancement in IEEE802.11 WMNs.

Mattavelli","doi":"10.1109/ISCE.2008.4559414","DOIUrl":"https://doi.org/10.1109/ISCE.2008.4559414","url":null,"abstract":"Summary form only given. Multimedia coding technology, after about 20 years of active research, has delivered a rich variety of different and complex coding algorithms. Selecting an appropriate subset of these algorithms would, in principle, enable a codec designer to produce any desired trade-off between compression performance and implementation complexity. Currently, interoperability demands that this selection process be ldquohard-wiredrdquo into the normative description of the codec, or at best, a number of choices codified within the media syntax (i.e MPEG profiles). This talk presents an alternative paradigm for codec deployment that is currently under development by MPEG, known as Reconfigurable Video Coding (RVC). Using RVC, the final objective is to enable arbitrary combinations of fundamental algorithms to be assembled, without additional standardization steps, because everything necessary for decoding is delivered alongside the content itself. The side-information consists of a description of the content syntax, as well as a description of the decoder configuration. Decoder configuration information is provided as a description of the interconnections between algorithmic blocks. The approach is based on describing all ldquoalgorithmsrdquo under the form of ldquolibraryrdquo of coding algorithms using CAL formalism and an XML dialect for the description of the configuration. The talk will briefly summarize the status of the RVC standardisation process, the different objectives from the point of view of a standard body, the technical problems solved so far, the open issues, and the interest and tools needed to support RVC specification on reconfigurable platforms.","PeriodicalId":378486,"journal":{"name":"2008 IEEE International Symposium on Consumer Electronics","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122478938","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

First, we observe that the correlation values between the time-delayed pseudo noise code and received signal remain almost unchanged, due to the multipath signals being received later than a line-of-sight signal. Based on this observation, we propose a novel delay tracking scheme for Galileo L1 OS systems. The simulation results demonstrate that the proposed scheme outperforms the conventional scheme in terms of the tracking bias and its running average in static channels. Also, mean and variance of tracking bias are evaluated in static channels with additive white Gaussian noise.","PeriodicalId":378486,"journal":{"name":"2008 IEEE International Symposium on Consumer Electronics","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126308107","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

SDRs realized so far are mostly part of communication technology, including audio broadcast receivers. Image- and video processing in SDRs is not common due to the fact that this type of real-time application requires a huge amount of processing resources. It can be foreseen that SDRs for video processing will be the next attractive approach for flexible and cost-effective media systems. We started with functional diagrams of the required modules for TV receivers, selected suitable algorithms to estimate their computational complexity and investigated their resource-quality scaling properties. Thereafter benchmark tests were done for a variety of common general purpose processors (GPPs), showing that real-time performance will be possible in the near future.","PeriodicalId":378486,"journal":{"name":"2008 IEEE International Symposium on Consumer Electronics","volume":"69 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131406558","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While obtaining information from the Internet, it is usual to create individual profiles in order to consume personalized content based on the users preferences, e.g. within news portals. The traditional broadcast domain does not offer such functionality by default. But there are still a number of scenarios for personal TV imaginable. This paper describes two of such scenarios, dealing with cross-modal audio-visual analysis methods. Furthermore, a system based on news segmentation and a news clip module is presented. The news segmentation algorithm uses a knowledge-based approach and decision rules, whereas the annotation algorithm focuses on text capturing components e.g. optical character recognition and speech recognition. Finally, the results of an in-depth evaluation based on German newscasts in TV are presented.","PeriodicalId":378486,"journal":{"name":"2008 IEEE International Symposium on Consumer Electronics","volume":"14 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131793957","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
