可伸缩视频编码并行方法研究与应用的中期报告 DearSir/Madam, Iamwritingtoprovideaprogressreportonmyresearchontheparallelmethodofscalablevideocodinganditsapplications. Inthefirstphaseofmyresearch,Iconductedathoroughliteraturereviewtogaininsightsintotheexistingparallelcodingmethodsandidentifythegapsinthecurrentresearch.Basedonthegapsidentified,Idevelopedaparallelscalablevideocodingmethodthatcouldefficientlydistributethecomputationloadacrossmultipleprocessingunits.TheproposedmethodalsoemployedahybridcodingapproachthatcombinedtheadvantagesofwavelettransformandH.264/AVCcodingstandards. Inthesecondphaseofmyresearch,Idesignedandimplementedaparallelscalablevideoencoderusingtheproposedmethod.Theimplementationwascarriedoutonaclusterofprocessorswithasharedmemoryarchitecturetotakeadvantageofthefastcommunicationbetweentheprocessors.Theexperimentalresultsshowedthattheparallelencoderachievedhighspeedupandscalabilitywithalowoverheadincomparisontothesequentialencoder.
