Topic: LZW decompression in PDF streams

I have a weird problem, while decompressing PDF streams, compressed with LZW algorithm. In fact everything is fine, until length of codes goes from 9 to 10 bits. At this very point algorothm starts reading from the stream values that are not yet in the compression table.
I wonder if there are any specific things, used by PDF that makes it different from classical compression/decompression technics, described by Ziv and Lempel?
Thanks a lot in advance.
