-When enabled, coefficients are transmitted in order of visual importance:
-1. LL subband of highest decomposition level (thumbnail)
-2. Lower frequency subbands first

-## Motion Compensation
-- Search range: ±28 pixels (optimized for 112x112 tiles)
-- Sub-pixel precision: 1/4 pixel with bilinear interpolation
-- Tile size: 112x112 pixels (perfect fit for TSVM 560x448 resolution)
-  * Exactly 5×4 = 20 tiles per frame (560÷112 = 5, 448÷112 = 4)
-  * No partial tiles needed - optimal for processing efficiency
-- Uses Sum of Absolute Differences (SAD) for motion estimation
-- Overlapped block motion compensation (OBMC) for smooth boundaries

+- 280x224 DWT tiles vs 16x16 DCT blocks in TEV
 - Multi-resolution representation enables scalable decoding
 - Better frequency localization than DCT
 - Reduced blocking artifacts due to overlapping basis functions
-- Region-of-Interest (ROI) coding for selective quality enhancement
