MoM is not sufficiently efficient at high frequencies, PO and GTD based techniques give acceptable results only for certain class of problems, while hybrid techniques still evolve. In this paper we present a new method for analysis of large scatterers, based on iterative solution of MFIE. Simple concept and low memory requirements of the method are followed by reasonable accuracy of results.","PeriodicalId":422115,"journal":{"name":"TELSIKS 2005 - 2005 uth International Conference on Telecommunication in ModernSatellite, Cable and Broadcasting Services","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"131996163","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}

The huge benefits of digital contents leading to the explosion of multimedia industries are also responsible for the huge piracy. The weapons against this piracy are technology and legislation, defining digital rights management (DRM), able to protect and enforce the rights associated to the digital content. The paper discusses the necessity of intellectual rights protection generally and the concepts of DRM in today's life. It also presents the state of art concerning encryption and watermarking, the main technical solutions for DRM, and discusses the challenges and new directions for this topic.","PeriodicalId":422115,"journal":{"name":"TELSIKS 2005 - 2005 uth International Conference on Telecommunication in ModernSatellite, Cable and Broadcasting Services","volume":"215 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121726883","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}
