SPIHT Coding Example: Pass 1, Refinement Step
S = (0,0), (0,1), (1,0), (1,1),
(0,2), (0,3), (1,2), (1,3),
(2,0), (2,1), (3,0), (3,1),
(4,2), (4,3), (5,2), (5,3)
Z = (R,1,1), (R,3,1), (R,3,0),
one bit for each member of S.
37 total bits in pass 1 were output.
Initialization was 4 bits.
Total of 41 bits to send 64 bits plus
