Abstract: A method is disclosed for performing bi-directional synchronization between a host device having a large capacity, e.g., a personal computer (20), in which a dedicated application program is installed and a mobile media player device (10) using play lists. The mobile media player device (10) is capable of independently downloading media content including audio and video files and creating play lists therefrom. Upon connecting the personal computer (20) and the media player (10) play lists marked for synchronization are downloaded from the media player (10) to the personal computer (20) wherein the dedicated application program uses time and date information of the play lists to determine which play lists of the personal computer (20) and media player (10) are to be updated. The updated play lists are stored on the respective devices (10, 20).

Abstract: An electronic program guide (100) includes a first list (105) with first information and a second list (110) which is displayed concurrently with the first list (105) in response to selection of a selected information (115) from the first information, which includes a channel list, a theme list, a time list, a favorite list or a reminder list, switchable in response to activation of a programmable perspective switch (155, 250). The first list (105) is displayed in response to accessing the electronic program guide (100), such as by activating an access switch (240) of a remote controller (200). Both the first and second lists are displayed in response to accessing the second list, such as by double clicking on the access switch (240) or activating a program switch (245) of the remote controller (200). The second list includes information associated with the selected information from the first list.
