bzip1 uses arithmetic encoding which is heavily patented. bzip2 uses huffman instead, which isn't, but is slightly (10% is often quoted) less efficient. I guess bzip3 could use range coding which is supposedly patent-free[1] and has similar compression ratio than arithmetic coding.
OG.
[1] I guess everything is in the way it is written, since I have a very hard time understand where the difference is between range coding and arithmetic coding. - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
