    Abstract: A first portion of programming aired prior to a first time is obtained via a unicast session with a server, the first portion including previously aired programming. When the programming data being sent via the unicast session catches up to a multicast broadcast of the programming, the unicast session is terminated and a switch is made to obtaining a remaining portion of the programming from a different source other than the server. This different source can be, for example, a local storage device or a multicast broadcast of the programming.
