Since real P2P systems exhibit considerable heterogeneity in hardware, software and network connections, the design of P2P streaming networks must factor in this variation. There are two different sources of heterogeneity in P2P networks. Most existing work in the literature handle heterogeneity among receivers and requirements by the use of different multimedia encodings of the same content. In this paper we focus on the problems caused by heterogeneity in the network delays connecting receivers to the sender We assume that there is a single multicast tree and a single video stream. We propose new algorithms for building multicast trees for multimedia streaming in heterogeneous P2P networks. Our algorithms differ in the amount of communication and computational resources they require. We compare the performance (using simulations) of our algorithms with an existing Zigzag algorithm. Our results show that two of our algorithms ( FollowTree-Landmark-II algorithm and FollowTree algorithm) significantly outperform Zigzag.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"9 5","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132973834","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}

This server is intended to be used in voice over IP systems for audio interaction with users, NAT traversal, call monitoring and media recording. Its advantage is that it is application independent, which means that it can be used by any service and for any signaling protocol. In this paper we describe the design of the server, of its control protocol and of its functionalities such as file playing, DTMF detection, RTP proxying and audio recording. For file playing, we propose an approach to schedule RTP packet transmission that overcomes the irregularity of event scheduling of the operating system and for conversation recording, we propose an original approach to synchronize media streams that allows to avoid voice overlap while recording a conversation. We have conducted many experiments on the media server. We evaluated the accuracy of the file playing timing under different load conditions, the effect of the RTP proxying on the media quality and the subjective quality of recorded conversations. The results of these experiments show the great impact of the load of the media server on the performance of its functionalities, the improvement that the packet scheduling algorithm brings to the precision of inter-departure timing, and the good subjective quality of the recorded conversation using our synchronizing approach.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133943532","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 the MPEG-4 specifications, body animation parameters (BAPs) and body definition parameters (BDPs) allow virtual bodies and their animation to be compressed using a standard compression pipeline comprising of quantization, predictive encoding and arithmetic coding of these parameters. In this paper, we propose and implement a new stage within the standard prediction-based compression pipeline for the BAPs, termed as BAP sparsing. BAP sparsing compresses a complete block of motion data, consisting of an initial 1-frame followed by subsequent P-frames, required for creating the animation. It exploits the inherent hierarchical structure of the human skeletal model to intelligently drop and modify the P-frames, while preserving animation quality. BAP sparsing is shown to result in superior compression of the BAP data, with negligible loss in the motion animation quality. It is also shown to result in a lower network throughput requirement and fewer CPU cycles on the client end to create the animation. The proposed method is particularly well suited for animation using BAP data.","PeriodicalId":255955,"journal":{"name":"2005 Systems Communications (ICW'05, ICHSN'05, ICMCS'05, SENET'05)","volume":"66 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-08-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124920028","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}
