Abstract
A method includes receiving, at a service delivery platform system from a first video source, a control stream associated with a media content stream delivered via a media distribution network. The control stream includes conditional access information for the media content stream including a restriction condition to delivery of the media content stream. The method includes parsing, at the service delivery platform system, the conditional access information to create a substitute table for a head end of the media distribution network that will implement the restriction condition. The substitute table indicates a condition for delivery of a substitute media content stream, a start time, an end time, and a second content source for the substitute media content stream. The method also includes sending the substitution table to the head end from the service delivery platform system to automatically schedule a conditional access event that implements the restriction condition.
