Abstract

A docking assembly serves as an interface between (1) a portable digital media storage and playback (PDMSP) device, and (2) a media reproduction system. A remote controller preferably controls the docking assembly and PDMSP device, which may receive electric charge from the assembly. Media reproduction systems may reproduce audio and video signals in user-perceptible form. Telephonic relay capability is further provided between a telephonic PDMSP playback device and a telephonic remote controller by way of a telephone rebroadcast receiver associated with the docking assembly. Methods for downloading digital media files, and for creating or modifying playlists with a remotely controllable docking assembly adapted to provide a television-compatible video output signal, are further provided.
