System and method of restricting access to media content

A system comprising:

• a processor;
• and
• a memory including instructions that, when executed by the processor, cause the processor to perform operations including:
• receiving, from a first video source, a control stream associated with primary media content delivered via a video distribution network, wherein the control stream includes first conditional access information associated with a first geographic area and second conditional access information associated with a second geographic area, and wherein the first conditional access information of the control stream indicates a restriction of the primary media content;
• identifying a first particular second video source from a plurality of second video sources, the first particular second video source identified based on the first geographic area;
• sending a first substitution table entry to the first particular second video source, but not to at least one other video source of the plurality of second video sources, the first substitution table entry created based on the first conditional access information, wherein the first substitution table entry indicates first substitute media content to be output, by the first particular second video source in response to the restriction, in place of the primary media content;
• identifying a second particular second video source from the plurality of second video sources, the second particular second video source identified based on the second geographic area;
• and
• sending a second substitution table entry to the second particular second video source, the second substitution table entry based on the second conditional access information, wherein the second substitution table entry indicates second substitute media content to be output, by the second particular second video source in response to the restriction, in place of the primary media content.

A computer-readable storage device including instructions that, when executed by a processor, cause the processor to perform operations including:

• receiving, from a first video source, a control stream associated with primary media content delivered via a video distribution network, wherein the control stream includes first conditional access information associated with a first geographic area and second conditional access information associated with a second geographic area, and wherein the first conditional access information of the control stream indicates a restriction of the primary media content;
• identifying a first particular second video source from a plurality of second video sources, the first particular second video source identified based on the first geographic area;
• sending a first substitution table entry to the first particular second video source, but not to at least one other video source of the plurality of second video sources, the first substitution table entry created based on the first conditional access information, wherein the first substitution table entry indicates first substitute media content to be output, by the first particular second video source in response to the restriction, in place of the primary media content;
• identifying a second particular second video source from the plurality of second video sources, the second particular second video source identified based on the second geographic area;
• and
• sending a second substitution table entry to the second particular second video source, the second substitution table entry based on the second conditional access information, wherein the second substitution table entry indicates second substitute media content to be output, by the second particular second video source in response to the restriction, in place of the primary media content.
