FloatsomNJetsom writes "High Definition Content Protection is supposed to make sure you're not playing pirated content, but sometimes your devices screw up the HDCP "handshake" (over an HDMI cable) and nothing works. This happens with some regularity with the PS3, and Popular Mechanics investigated and found a quick and dirty workaround. From the article:
The problem isn't limited to the PS3 — many HDTV cable boxes and have the same problem. The fix there? Unplugging the power cable."
We then checked with Leslie Chard, president of HDMI Licensing, which owns the rights to the standard, who told us that HDCP is one component of HDMI that has been plagued with interoperability issues. HDCP (high-bandwidth digital content protection) is designed to prevent the interception of data — specifically copyrighted Hollywood movies — between an output component and a display. As Steve Balough, the president of Digital Content Protection, the licensing company for HDCP explains, the two pieces of hardware must exchange a "key," a sort of certificate of authenticity unique to each individual device, to verify a secure connection.
