This method not only can acquire the optimal control point in the rate-distortion curve from the global perspective under the code error environment, but also can self adaptive adjust the bit allocation and the quantization parameter under given network bandwidth. Furthermore, it can also implement intra frame macro block refresh at the same time and play important role in counteracting the channel code error to minimize the total distortion under certain bit-rated according to current network package loss probability, by which to establish the rate distortion model of associated signal source channel and apply the rate-distortion optimized solution method to optimal allocate the bit-rate between the signal source coding and the channel coding. This method can provide valuable reference for the video robust coding transmission and resource allocation under the wireless environment.","PeriodicalId":360757,"journal":{"name":"Second International Conference on Embedded Software and Systems (ICESS'05)","volume":"105 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122696799","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 context of control applications, the goal of high control performance and low energy consumption are at odds with each other. While dynamic voltage/frequency scaling (DVS) has proved to be promising in energy saving while preserving task schedulability, traditional DVS algorithms use either open loop or ad hoc solutions, and hence cannot perform well for dynamic systems where the workload varies significantly. By targeting these systems, a novel scheme, namely DVS-FS, which combines DVS and feedback scheduling, is suggested. The objective is to save CPU energy as much as possible, while still providing control performance guarantees, which largely depends on successful schedule of the control task set. DVS-FS exploits feedback control methodology, and facilitates tradeoffs between energy consumption and control performance through controlling the CPU utilization at a considerably high level. Simulation experiments demonstrate that DVS-FS can easily reduce significant energy consumption at the expense of only minor control performance degradation.","PeriodicalId":360757,"journal":{"name":"Second International Conference on Embedded Software and Systems (ICESS'05)","volume":"15 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2005-12-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126762054","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}
