摘要：A method includes receiving, at a service delivery platform system from a firstvideo source, a control stream associated with a media content stream delivered via amedia distribution network. The control stream includes conditional access information

for the media content stream including a restriction condition to delivery of the mediacontent 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 themedia distribution network that will implement the restriction condition. The substitutetable 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. Themethod also includes sending the substitution table to the head end from the servicedelivery platform system to automatically schedule a conditional access event thatimplements the restriction condition.
