We consider combing soft real-time video streaming scheduling with threshold to minimize the ineffective preemption. Based on the value density and urgency of soft real-time task, the dynamic scheduling with preemption threshold strategy (DSPT) is proposed in the paper. By analyzing the response time and preemption relationship of tasks, the preemption thresholds are assigned. Simulation results show that the DSPT strategy achieves improvements about success rate, delay time, and benefit of the system.<\/jats:p>","DOI":"10.1155\/2019\/5284968","type":"journal-article","created":{"date-parts":[[2019,1,1]],"date-time":"2019-01-01T18:31:33Z","timestamp":1546367493000},"page":"1-7","source":"Crossref","is-referenced-by-count":4,"title":["Dynamic Soft Real-Time Scheduling with Preemption Threshold for Streaming Media"],"prefix":"10.1155","volume":"2019","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-4075-3512","authenticated-orcid":true,"given":"Wenle","family":"Wang","sequence":"first","affiliation":[{"name":"School of Software, Jiangxi Normal University, Nanchang 330022, Jiangxi, China"}]},{"given":"Yuan","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Software, Jiangxi Normal University, Nanchang 330022, Jiangxi, China"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4893-3750","authenticated-orcid":true,"given":"JiangYan","family":"Dai","sequence":"additional","affiliation":[{"name":"School of Computer Engineering, Weifang University, Weifang 261061, Shandong, China"}]},{"given":"Zhonghua","family":"Cao","sequence":"additional","affiliation":[{"name":"School of Software & Communication Engineering, Jiangxi University of Finance and Economics, Nanchang 330038, Jiangxi, China"}]}],"member":"311","reference":[{"key":"1","doi-asserted-by":"publisher","DOI":"10.1109\/TNET.2013.2253797"},{"key":"2","doi-asserted-by":"publisher","DOI":"10.1109\/MCOM.2012.6178830"},{"key":"3","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2014.140403"},{"issue":"1","key":"4","volume":"2017","year":"2017","journal-title":"Eurasip Journal on Image and Video Processing"},{"key":"6","doi-asserted-by":"publisher","DOI":"10.1109\/TMM.2014.2357716"},{"key":"7","doi-asserted-by":"publisher","DOI":"10.1109\/TMM.2015.2425228"},{"key":"8","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvcir.2016.11.014"},{"key":"9","doi-asserted-by":"publisher","DOI":"10.1109\/TCSVT.2014.2357094"},{"journal-title":"Applied Soft Computing","year":"2017","key":"10"},{"key":"11","doi-asserted-by":"publisher","DOI":"10.1186\/s13638-016-0728-8"},{"key":"15","doi-asserted-by":"publisher","DOI":"10.1002\/dac.2422"},{"key":"16","doi-asserted-by":"publisher","DOI":"10.1007\/s11554-016-0629-4"},{"key":"17","doi-asserted-by":"publisher","DOI":"10.1109\/JSAC.2014.140411"},{"key":"19","doi-asserted-by":"publisher","DOI":"10.1109\/ACCESS.2017.2731899"},{"key":"20","doi-asserted-by":"publisher","DOI":"10.1007\/978-3-319-30695-7_12"},{"issue":"2","key":"22","first-page":"01","volume":"4","year":"2017","journal-title":"Leibniz Transactions on Embedded Systems"},{"key":"23","doi-asserted-by":"publisher","DOI":"10.1109\/TMC.2015.2426710"},{"key":"24","doi-asserted-by":"publisher","DOI":"10.1109\/TVT.2015.2504455"}],"container-title":["International Journal of Digital Multimedia Broadcasting"],"original-title":[],"language":"en","link":[{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2019\/5284968.pdf","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2019\/5284968.xml","content-type":"application\/xml","content-version":"vor","intended-application":"text-mining"},{"URL":"http:\/\/downloads.hindawi.com\/journals\/ijdmb\/2019\/5284968.pdf","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2019,1,1]],"date-time":"2019-01-01T18:31:38Z","timestamp":1546367498000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.hindawi.com\/journals\/ijdmb\/2019\/5284968\/"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2019,1,1]]},"references-count":18,"alternative-id":["5284968","5284968"],"URL":"https:\/\/doi.org\/10.1155\/2019\/5284968","relation":{},"ISSN":["1687-7578","1687-7586"],"issn-type":[{"type":"print","value":"1687-7578"},{"type":"electronic","value":"1687-7586"}],"subject":[],"published":{"date-parts":[[2019,1,1]]}}}
