I'm made some changes / additions to the resources listings in the right-most column. Audible Magic has been moved from Watermarking to Fingerprinting. Thanks to DM for pointing out that I had misunderstood them. I'll be adding to the Fingerprinting list in the near future.
In the IPTV group, I've added pointers to NDS, SecureMedia, Nagra, and Widevine.
