You seem to assume that codebooks always begin on byte boundaries. This
is not necessarily true, since the length of a codebook is not
necessarily a multiple of 8 bits. The first codebook will begin on a
byte boundary, and a few others might begin on a byte boundary simply by
coincidence, but in general a codebook can begin anywhere within a byte.

The sync pattern is not a 3 byte pattern. It's a 24 bit pattern that
should immediately follow the last *bit* of the previous codebook.

Hope this helps,
