~~~~~~~~~~~~~~~~Processing Abstract- We present a multiple description videocodingwill beavailable tothedecoder. Although thisapproach will scheme basedonH.264/AVC.

Please refer to(2)fora survey of fining decoding ofmorethanonedescription ispossible with moderate pre-processing on thebitstreamlevel. Theschemerateapproaches. Recently, somescalable MDVC systems allows forfine-granular control ofredundancy.
