Abstract
A content provider transmits instructions to a content receiver to record multiple instances of content. The instances of content are included in the same frequency band of a broadcast transmitted by the content provider via a first communication link and scrambled utilizing the same control word. The content provider determines to supplement the multiple instances of content and transmits an instruction to record a supplemental instance of content from a second content provider via a second communication link. The content receiver receives the instructions and accordingly receives, descrambles, and stores the multiple instances of content and the supplemental instance of content. In some implementations, the first communication link may be a satellite communication link and the second communication link may be a different type of communication link such as a terrestrial broadcast communication link and/or an Internet protocol communication link.
