How Does HDCD Work?

HDCD says it delivers 20-bit encoded sound on CDs. But because CDs are a 16-bit technology, how is it able to do this? Is it using some unused reserved space for the 4 additional bits of data? Or is it another method?

"The process allows 20-bits of data to be recorded into the standard 16-bit CD format. This is done using a patented “digital watermarking” technology which encodes the extra 4 bits of data into the least significant bit of the 16-bit word length. As a result, more data can be stored ensuring better frequency response, extended dynamic range, greater richness and musical fidelity to any project."
