In a broadband communication network, a method ( 400 ) for delivering content to a consumer network device. The method includes: managing ( 402 ) an original data stream carrying the content, the original data stream having original recurring access units ("RAUs") usable by the consumer network device to acquire the content; replicating ( 404 ) the original data stream to form a replicated data stream having replicated RAUs; offsetting the replicated data stream (and the replicated RAUs) relative to the original data stream by an amount of time; and arranging ( 408 ) for communication of the amount of time to the consumer network device. The amount of time is usable ( 410 ) by the consumer network device to determine a next available RAU from among at least one of the original RAUs and at least one of the replicated RAUs, and the next available RAU is usable by the consumer network device to acquire the content.
