Selectable Output Control (SOC) is a content protection Digital Rights Management (DRM) technology that is incorporated into approved devices that enables a Multichannel Video Programming Distributor (MVPD) to disable non-secure audio-video output by encoding the video with a specific signal.
When SOC is enabled for a program, televisions that do not have an HDMI port or are not HDCP compliant will not be able to view content.
The MPAA argued that member companies (studios) would not agree to releasing these movies to the On-Demand market without the ability to enforce copy protection, which analog outputs such as component video connections lack, leaving open the ability of users to record analog output.
The FCC cited an example using homebound parents with young children that may have a hard time getting to the movies due to not being able to find a babysitter.
The American Association of People with Disabilities is also in favor of the MPAA's plan to offer high-definition first run movies before home video release because it would increase the entertainment options that disabled Americans have in the home.
