The Grand Alliance (GA) MPEG\u20102\u2010based HDTV codec achieves a high degree of source and channel coding efficiency while preserving the delivery of high\u2010resoultion picture quality in a variety of video input and output formats in bandwidth\u2010limited channels. The video source decoder hardware architecture necessary to achieve the data decoding and ensuing video postprocessing poses numerous technologic challenges to the system designer, who must tradeoff minimizing codec constraints with the eventual commercialization of a video decoder for a consumer television receiver product. The powerful and flexible coding algorithm necessary to satisfy the HDTV picture quality and transmission channel bandwidth limitation requirements results in an encoder\u2010output bitstream that necessitates high throughout decoding. Although the transmitted bitstream is of constant rate due to rate buffering, bistreams internal to the codec are both peaky and bursty. An intelligent distributive parallel processing decoding architecture has been developed to dynamically partition the MPEG\u20102 bitstream into a number of decodable subset bitstreams, while placing minimal constraints on the encoding algorithm. This architecture allows for high\u2010speed, efficient decoding of the bitstream, and can be a prelude to the development of a cost\u2010effective consumer product. Further architecture refinements can be explored, including implementation in VLSI.<\/jats:p>","DOI":"10.1002\/ima.1850050405","type":"journal-article","created":{"date-parts":[[2007,3,5]],"date-time":"2007-03-05T23:10:53Z","timestamp":1173136253000},"page":"263-267","source":"Crossref","is-referenced-by-count":1,"title":["Grand alliance MPEG\u20102\u2010based video decoder with parallel processing architecture"],"prefix":"10.1002","volume":"5","author":[{"given":"Kiran","family":"Challapali","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alan","family":"Cavallerano","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Richard","family":"Shen","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Olu","family":"Akiwumi\u2010Assani","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aldo","family":"Cugnini","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlo","family":"Basile","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2005,10,20]]},"reference":[{"key":"e_1_2_1_2_2","unstructured":"\u201cGeneric coding of moving pictures and associated audio \u201d ISO\/IEC JTCI\/SC29\/WG11\u2014138180\u20102 (Draft International Standard) March1994."},{"key":"e_1_2_1_3_2","unstructured":"\u201cGrand Alliance HDTV system specification \u201d Submitted to the FCC Advisory Committee on Advanced Television Services by the Grand Alliance April1994."},{"key":"e_1_2_1_4_2","unstructured":"\u201cAdvanced digital television\u2014system description \u201d Submitted to the FCC Advisory Committee on Advanced Television Services by the Advanced Television Research Consortium April1994."},{"key":"e_1_2_1_5_2","unstructured":"\u201cDigital spectrum compatible\u201d Monograph with technical details of the DSC\u2010HDTV system published by Zenith Electronics Corporation and AT&T September1991."},{"key":"e_1_2_1_6_2","unstructured":"\u201cDIGICIPHER HDTV system description \u201d submitted to the FCC Advisory Committee on Advanced Television Services by the American Television Alliance August1991."},{"key":"e_1_2_1_7_2","doi-asserted-by":"publisher","DOI":"10.1002\/ima.1850050403"},{"key":"e_1_2_1_8_2","unstructured":"J.Maihot \u201cArchitecture and Implementation of the Grand Alliance HDTV video encoder \u201d appearing in this journal."},{"key":"e_1_2_1_9_2","unstructured":"K.Joseph T.Smith J.ZdepskiandM.Diess \u201cThe Grand Alliance transport system for terrestrial HDTV transmission \u201d appearing in this journal."},{"key":"e_1_2_1_10_2","unstructured":"\u201cHigh\u2010speed flexible variable\u2010length\u2010code decoder \u201d U.S. Patent No. 5 173 695 byM.\u2010T.SunandK.\u2010H.Tzou assigned toBell Communications Research Inc.
