ABSTRACT:
In one embodiment, a method includes receiving gap information from an entertainment content source configured to provide an entertainment stream associated with a contributing source information providing a source of the entertainment stream and a chronological order to render the entertainment stream, the entertainment stream being encrypted and having an associated first decryption key multiplexed into a key distribution system, the gap information identifying a gap in the entertainment stream where an ad may be one of inserted or substituted, synchronizing a target ad from an advertisement stream to a time base corresponding to the gap, decrypting the entertainment stream using the first decryption key selected from the key distribution system based on the contributing source information, and rendering the entertainment stream and the target ad as a composite stream based on the chronological order, the target ad being rendered during the gap in the entertainment stream.
