Conventional JSCD schemes, adopting low-density parity check (LDPC) codes for multimedia devices, typically operate at a fixed-time decoding loop, regardless of the quality of data received. We present a JSCD scheme that achieves reduction in power through minimum energy decoding and dynamic voltage and frequency scaling (DVFS). Consequently, up to 39% power reduction is achieved in Foreman, Akiyo, and Mobile video streams without performance degradation in reconstructed video quality.<\/jats:p>","DOI":"10.1145\/2220336.2220342","type":"journal-article","created":{"date-parts":[[2012,7,31]],"date-time":"2012-07-31T13:42:45Z","timestamp":1343742165000},"page":"1-21","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":2,"title":["Unequal Error Protection Based on DVFS for JSCD in Low-Power Portable Multimedia Systems"],"prefix":"10.1145","volume":"11","author":[{"given":"Yoon Seok","family":"Yang","sequence":"first","affiliation":[{"name":"Texas A&amp;M University"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Gwan","family":"Choi","sequence":"additional","affiliation":[{"name":"Texas A&amp;M University"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"320","published-online":{"date-parts":[[2012,7]]},"reference":[{"key":"e_1_2_1_1_1","doi-asserted-by":"publisher","DOI":"10.1109\/TCSI.2009.2023941"},{"key":"e_1_2_1_2_1","doi-asserted-by":"publisher","DOI":"10.1109\/26.990903"},{"key":"e_1_2_1_3_1","volume-title":"Proceedings of the Design, Automation and Test in Europe Conference (DATE). 1--6.","author":"Dielissen J."},{"key":"e_1_2_1_4_1","doi-asserted-by":"publisher","DOI":"10.1109\/TCSVT.2002.800309"},{"key":"e_1_2_1_5_1","doi-asserted-by":"publisher","DOI":"10.1109\/TIT.1962.1057683"},{"key":"e_1_2_1_7_1","volume-title":"Proceedings of the IEEE Workshop on Signal Processing Systems Design and Implementation. 122--127","author":"Glikiotis G."},{"key":"e_1_2_1_8_1","doi-asserted-by":"publisher","DOI":"10.1109\/VLSID.2007.19"},{"key":"e_1_2_1_9_1","article-title":"Stereo video transmission using LDPC code","author":"Guo R.","year":"2008","journal-title":"Int.
