Claim:
A method for transmitting requested content items in a broadband transmission system, said method comprising: receiving requests for a plurality of content items on an upstream path of said broadband transmission system; creating a list of said content items; creating a request count for each content item of said plurality of content items based on said requests received; sorting said requests using said request count; determining an associated retransmit rate for each of said content items, said content items with a higher request count receiving a higher associated retransmit rate than content items with a lower request count, the retransmit rate indicating how often said content items should be retransmitted; grouping content items with a request count greater than or equal to a second predetermined access count into a transmit group; determining a group retransmit rate for said transmit group; repeatedly broadcasting the content items at said associated retransmit rate; and repeatedly broadcasting the transmit group at said group retransmit rate.
