Abstract:
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.
