For every picture or for each group of contiguous pictures (GOP), the encoder generates an information set organized in a hierarchical layered structure. The base layer contains the information needed to a low quality video; the other layers contain data, which, if received and decoded, can enhance the video quality. The basic idea is to reserve bandwidth only to grant the transmission of base layer information, and modify the MAC scheme to manage the video enhancement data together with voice\/dota streams. by adaptively transmitting the increimental video information only it the performances of other traffic classes will not drop below a certain threshold. The aim or this proposal is the improvement of the video stream quality in low load conditions, without a significant reduction of other traffic classes performance during high load periods. Several simulation results show the effectiveness of the proposed method.<\/jats:p>","DOI":"10.1002\/ett.4460110406","type":"journal-article","created":{"date-parts":[[2008,9,12]],"date-time":"2008-09-12T13:55:26Z","timestamp":1221227726000},"page":"373-382","source":"Crossref","is-referenced-by-count":0,"title":["An Integrated Multiple Access and Hierarchical Coding Scheme for Video Communication on Wireless Networks"],"prefix":"10.1002","volume":"11","author":[{"given":"Raffaele","family":"Bolla","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Alessandro","family":"Iscra","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mario","family":"Marchese","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Carlo","family":"Nobile","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sandro Zappa","family":"Tore","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"311","published-online":{"date-parts":[[2008,9,12]]},"reference":[{"key":"e_1_2_1_2_2","unstructured":"IEEE Journal on Selected Areus in Communications 1997 14 6 Real time video services in multimedia networks"},{"key":"e_1_2_1_3_2","doi-asserted-by":"crossref","unstructured":"IEEE Communications Magazine 1999 37 1 Traftic management and switching for multimedia","DOI":"10.1109\/MCOM.1999.739270"},{"key":"e_1_2_1_4_2","doi-asserted-by":"crossref","unstructured":"IEEE Network 1998 12 6 Special Issue on Transmission and Distribution of Digital Video","DOI":"10.1109\/MNET.1998.752640"},{"key":"e_1_2_1_5_2","doi-asserted-by":"publisher","DOI":"10.1109\/98.736477"},{"key":"e_1_2_1_6_2","doi-asserted-by":"publisher","DOI":"10.1109\/98.736478"},{"key":"e_1_2_1_7_2","doi-asserted-by":"crossref","unstructured":"IEEE Journal on Selected Areas in Communications 1998 16 6 Wireless access broadband networks","DOI":"10.1109\/JSAC.1998.709445"},{"key":"e_1_2_1_8_2","doi-asserted-by":"publisher","DOI":"10.1109\/65.768484"},{"key":"e_1_2_1_9_2","unstructured":"Integrated Services Working Group.http:\/\/www.ietf.org\/html.chnrters\/intserv\u2010chnrter.html http:\/\/search.ietf.org\/rfc\/rfc I 8S9.txt."},{"key":"e_1_2_1_10_2","doi-asserted-by":"crossref","unstructured":"R.Braden L.Zhang S.Berson S.Herzog S.Jamin Resource Reservation Protocol (RSVP) \u2010 Version l Functional Specificntion.RFC 2205.Sep.1997 http:\/\/www.ietf.org\/rti\/rfc2205.txt.","DOI":"10.17487\/rfc2205"},{"key":"e_1_2_1_11_2","unstructured":"Integrated Services over Specific Link Layer.http:\/\/www.ictf.org\/httml.charters\/issll\u2010charter.html."},{"key":"e_1_2_1_12_2","unstructured":"Differentiated Services Working Group http:\/\/www.ietf.org\/html.charters\/diffserv\u2010charter.html."},{"issue":"6","key":"e_1_2_1_13_2","article-title":"An adaptive congestion control scheme for real time packet video transport","volume":"3","author":"Kanakia H.","year":"1995","journal-title":"IEEWACM Trans.
