But the hot degree of videos is changed dynamically. Now, there are only a few schemes with the capability of changing the bandwidth allocated to broadcast a video (also called channel transition) seamlessly and dynamically, such as SFB, SFB-With Preload, and SSB etc. But all of them are derived from Fast Broadcasting scheme, and have the same limit of low bandwidth utilization ratio. It can effectively improve the bandwidth utilization ratio that using lower channel bandwidth than video's playing rate, such as greedy equal bandwidth broadcasting (GEBB) scheme and poly-harmonic broadcasting (PHB) etc, but they do not change the bandwidth seamlessly and dynamically. Base on the characteristics, this paper proposed a new scheme, high performance seamless channel transition video-broadcasting scheme (HPSCT) with scalability and higher performance. Furthermore, with adoption of additional channels, the process of channel transition in HPSCT is transparent to clients and easier to be realized. The analysis of performance shows that HPSCT with scalability is more bandwidth-effective.","PeriodicalId":348977,"journal":{"name":"First International Conference on the Digital Society (ICDS'07)","volume":"4 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"128514115","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}

Such technologies offer new potential and can give rise to new problems for making the technology accessible to users. In this work we focus on integrated services for people with visual impairment. Web based information services have already been adapted for people with varying degrees of disability. What is needed now is a service oriented architecture that integrates information services with smart care technology such as sensor devices that generate data for input, processing, storage and query. The main new challenge we identified here is that users may be living in a perplexing contexture - a chain of barriers affecting their ability to live independently. Contexts such as mobility dependencies must therefore be recorded and used, indoors and outside. Users should be monitored during their interactions with services, and the meaning of their behaviour inferred in order to refine the services. Moreover, by giving a set of user scenarios, we present a higher level view of users' needs than single service invocation; alternatives and follow-on services might be suggested and previous interactions built upon. Management of the architecture must allow for incorporation of new technology and upgrade of services. Technology for smart care is developing rapidly; its usefulness, and acceptance, requires a dynamic and flexible architecture to support ease of management and use.","PeriodicalId":348977,"journal":{"name":"First International Conference on the Digital Society (ICDS'07)","volume":"506 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2007-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127600496","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}
