Napster co-founder Sean Parker has been working on his new service called Screening Room, which when becomes reality, could allow people to watch the latest Hollywood blockbusters in their living room as soon as they premiere at the box office. This week we get a glimpse at the kind of technologies Parker is using to ensure that the movies don't get distributed easily. From a report: Over the past several weeks, Screening Room Media, Inc. has submitted no less than eight patent applications related to its plans, all with some sort of anti-piracy angle. For example, a patent titled "Presenting Sonic Signals to Prevent Digital Content Misuse" describes a technology where acoustic signals are regularly sent to mobile devices, to confirm that the user is near the set-top box and is authorized to play the content. Similarly, the "Monitoring Nearby Mobile Computing Devices to Prevent Digital Content Misuse" patent, describes a system that detects the number of mobile devices near the client-side device, to make sure that too many people aren't tuning in. The general technology outlined in the patents also includes forensic watermarking and a "P2P polluter." The watermarking technology can be used to detect when pirated content spreads outside of the protected network onto the public Internet. "At this point, the member's movie accessing system will be shut off and quarantined. If the abuse or illicit activity is confirmed, the member and the household will be banned from the content distribution network," the patent reads. [...] Screening Room's system also comes with a wide range of other anti-piracy scans built in. Among other things, it regularly scans the Wi-Fi network to see which devices are connected, and Bluetooth is used to check what other devices are near.
