Exploiting temporal parallelism for software-only video effects processing
Ketan D. Mayer-Patel, Lawrence A. Rowe · 1998
hternet video is emerging as an important mtitimedia ap pHcation area.Video effects are important dernents in conventional video, but they are tiequently used in hternet ~ideo.Current hard~~based video effects proc~sing SG lutions ~e not w~matched for the ~+abti@ of kternet video (ie., bit rates, packet loss, jitter, etc.).A SO*+ ody solution, in contrast, provides the fl~ubtity to match this &[email protected] key to a sohe solution is to ~\Tloit pardeh~m.This paper presents the design of a pardel soti+ordy video Meets processing system and pretinary e~~erirnentd r~ts that mTlore the use of temporal pardl&~m.hternet packet video is emerging ~an important mtitim~ dia appEcation area The hltdticast Backbone (h~one) conferencing tool vic and NetJfeeting from hficrosoft are CSamplfis of bternet packet video conferencing took.Real Video tiom Re&Ne&orks.NetShow from hficrosoft, and IP/TV tiom Precept are axaples of vide~on-demand streaming hternet packet video applications.Th~e appEcations ~e used for a variety of purposw and audienc~s.using a vide~on-demand system, a single r~ cipient views stored material.Video conferencing is used by smti groups for meetings and by larger groups to attend re mote evmts (~g., classes, conference, concerts, etc.).Large broadcasts involve thousands of people %uned" into an ongokg program originating born eithw Eve sourc~or stored archives.For tfis paper, we group ~of these applications under the general term Internet Video (N).bternet video is &aractded by ~%abtity.Frame rates, bit ratw, and jitter are d variable in W applications.h contra~t, a tdevision system, whether adog or digitd, is &aracterized by constwt frame rates, bounded bit rates, and s.mchronous transmission.~appfimtions must *O ded n 036-S~9E!OOOS S5.
