Another theory that I read was that Sloot had somehow linked analog and digital (he was supposedly a TV technician before) and that he was parameterizing data from an analog signal using a small amount of data.
Now conspiracy theory or not; one can't claim that it's not an interesting read since he privately demonstrated it to at least 20 people and was also able to get Philips to work with him.
