Comparative analysis of temporal representations and concepts of time in chinese and english 中英文時間表征與中西時間觀對比探析
Because the conventional video coding schemes base on single antenna but not multiple antenna . the video signal should be decomposed into several sub-stream before it transmits over mimo-ofdm . this paper proposes a multiple description video coding scheme to match the multiple antenna system . we use a method based on 3d-sipht to re-arrange the coefficients into wavelet trees according to their spatio-temporal representation . each wavelet tree is coded and decoded independently, thus, the performance of error resilience for this scheme can be improved 本文提出的視頻多碼流分解是基于3d-spiht技術(shù)的改進(jìn),這種基于小波的信號分解產(chǎn)生的多零樹,可以通過對每個小波樹獨立的進(jìn)行高效壓縮編碼來增加傳輸魯棒性,壓縮產(chǎn)生的比特流可以靈活地組合成不同數(shù)量的碼流,這樣就同時兼顧了分解和壓縮。
