In the latest chip from cirrus the watermark detection is built in.
At this moment it's just not implemented. Perhaps it will be in the future perhaps not. It's too early to tell.The technology is not included in any playback device. The mark is completely embedded in the signal itself.
Philips demonstrated similar technology for sacd already with a demo where a handheld pda with a simple microphone was able to identify an embedded watermark within 3 seconds of playback.
A fact that wasn't highlighted and 'amplified' by the 'audiophile' press.It wasn't a dumb idea. I don't like it either but if it works out it's the best shot at real copy protection.
There are no (consumer) recording devices available yet for copying hirez multichannel content.At this time nobody can tell how it will work out.
