子頻帶/小波編碼是H.264/SVC標準中的一個架構，子頻帶編碼架構將小波轉換的原理套用在以離散餘弦轉換為基礎的H.264/SVC架構中。由於標準中的子頻帶編碼採用的9/7小波轉換需要較高的運算量和較複雜的運算複雜度。因此我們設計一個低運算量和低複雜度的子頻帶編碼架構，可以簡單的由JSVM架構修改成我們的子頻帶編碼架構。對於硬體的實現上，也可以較簡易的實現。本論文提出的架構在編碼效率上會略低於原始子頻帶編碼，但是還是會高於JSVM的編碼效率。

The subband/wavelet coding was adopted by the H.264/SVC standard. The SBC use 9/7 wavelet transform for DCT-based H.264/SVC. The 9/7 DWT need lots of computation and increase complexity. We proposed a new SBC structure for low complexity. For hardware, the new SBC structure is easy for implementation. The compression efficiency of the new SBC is higher than JSVM, and lower than SBC. But the efficiency between the new SBC and SBC is similar.
