    摘要： A system that incorporates teachings of the present disclosure may include, for example, a server having a controller to maintain content rights parameters associated with media content and a user where the content rights parameters include limits to distribution of the media content to a plurality of communication devices associated with the user and where a portion of the plurality of communication devices use different communication protocols from another portion of the plurality of communication devices, monitor for access to the media content by one communication device of the plurality of communication devices of the user, and obtain rights control data that is adapted to allow for presentation of the media content by the one communication device of the user where the rights control data is generated based on the content rights parameters. Other embodiments are disclosed.

    摘要： 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.

    摘要： A method includes receiving, at a service delivery platform from a first video source, a control stream associated with primary media content delivered via a video distribution network, where the control stream includes conditional access information associated with a second video source, wherein the conditional access information of the control stream indicates a restriction of the primary media content. The method also includes creating a substitution table, at the service delivery platform, based on the conditional access information including an indication of a geographic area, where the substitution table correlates the primary media content with substitute media content of the second video source, and when the restriction prevents access to the primary media content, the substitute media content is provided via the video distribution network. The method further includes sending the substitution table to the second video source.
