Abstract

Systems and methods are operable to retrieve a previously broadcast initial portion of a media content event. An exemplary embodiment stores a media content event at a first media device as the media content event is communicated over a broadcast system; receives a request at the first media device from a second media device, wherein the request identifies an initial portion of a media content event that has previously been communicated over a broadcast system; identifies the initial portion of the media content event from the stored media content event; retrieves the identified initial portion of the media content event; and communicates the initial portion of the media content event from the first media device to the second media device.
