The Digital Video Broadcasting (DVB) Portable Content Format (PCF) is a standard platform-independent service description which specifies the viewer experience in an iTV platform. It allows a unified authoring through a later transcoding to the final device. This paper proposes a workflow to produce and maintain platform-independent web-based iTV services from the application design level to the final deployed service through that standard. Moreover, this paper details the main characteristics of an implemented PCF to web-based platform transcoder, which can be applied to most IPTV and WebTV platforms.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"03 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"129854103","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}

In this paper, we propose a new mobile multicast method based on Two-Hop Multicast Listener Discovery (THMLD) protocol which provides the mobile multicast membership management function by forwarding the MLD messages to its neighboring subnets. To evaluate its performance, we set up the simulation platform and compare it with the traditional mobile multicast methods. The simulation results show that the proposed method can reduce the multicast join delay significantly.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127872840","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}

But in recent years, many high-speed congest control algorithms have been proposed for fast data transfer over high speed and long distance networks, and many operating systems take the high-speed TCP variations as default: the Linux kernel uses CUBIC TCP as default since version 2.6.18, while Compound TCP becomes default TCP in Windows Server 2008 and a part of Microsoft Windows Vista, where it is easy to be enabled. As there are still not sufficient and comprehensive performance comparison of the high-speed TCP variations, the deployment of them as default TCP in the operating systems raises concerns about the future of congest control in the internet and worries about the fairness problem. This paper is an attempt to evaluate the fairness of the default TCP in the newest Linux and Microsoft Windows. The simulation results indicate that between CUBIC TCP and Compound TCP it indeed exhibits unfairness. The CUBIC TCP is too aggressive to the Compound TCP in the high bandwidth-delay product network, and the performance of Compound TCP is unacceptable comparing to CUBIC TCP.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132324343","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}

However, IEEE 802.11 does not support reliable multicast due to its inability to exchange ACKs with multiple recipients and the influence of signal interference, congestion and hidden terminal problems. It is not suitable for the real-time multimedia transmission in this environment. In this paper, we propose a new reliable multicast scheme to solve the above problems by using a three-layer scheme. Our simulation results show that the performance of the wireless network with this proposed reliable scheme is much better than the original 802.11 protocol. The loss rate of the packets transmitted in this reliable 802.11 environment decreased a lot and the throughput of this reliable wireless environment performed constantly well compared with the original 802.11 protocol for mobile nodes.","PeriodicalId":267128,"journal":{"name":"2009 2nd IEEE International Conference on Broadband Network & Multimedia Technology","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2009-12-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127149032","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}
