ABSTRACT:
Improved approaches for delivering media programs to viewers (e.g., subscribers) are disclosed. The media programs are typically broadcast in accordance with a schedule. The media program can be delivered to viewers through multicast or unicast. According to one aspect, the media programs are buffered (e.g., cached) in a data packet format such that producing unicasts for particular viewers requires less computation and resources such that more concurrent unicasts are able to be effectively supported.
