The present invention discloses methods and systems for switching between media channels. Pursuant to these methods and systems, a broadcast source may provide multicast streams to client devices for presentation of media channels to a user. When a client device requests to switch channels, a client device that is receiving the requested channel initially transmits a unicast stream for the requested channel to the client device switching channels. The requesting client device upon receipt of this unicast stream may then provide the corresponding channel to the user.
