Abstract
A media device and methods that identify playback states reachable from a current content playback state and identify a reachable state that is likely to occur, are disclosed. A memory associated with the media device may receive frames that enable a smooth transition between the playback state and the reachable state. The media device may receive frames that correspond to points in the content that are separated by an amount of time that is proportional to the playback rate of the likely state. The frames may be frames corresponding to an image that may be played back at the playback rate of the likely state.
