After the device 10 plays a multimedia file, the first record module 1006 updates the local play history 1062 in the storage unit 106. After the device 10 establishes communication with a PC or other external storage device, the updating module 1008 obtains multimedia files from the PC or any other external storage device, thereby updating the multimedia files 1060 in the storage unit 106.
The device 10 has a plurality of operation options. In each of the operation options, the device 10 can perform a particular function. In the embodiment in FIG. 3, a first user interface 30 of the device 10 illustrates two options, i.e., a play multimedia files option 31 and a search files option 32. The play multimedia files option 31 is a play on local device (the device 10) option and the search files is a play on remote device (the multimedia system 20) option. The device 10 and the multimedia system 20 all can play multimedia files. The options are selectable through the input unit 107 to control the device 10 to be in the play multimedia files 31 or the search files 32.
When the processing unit 100 receives a play instruction from the input unit 107 corresponding to the play multimedia files 31, the device 10 reads a play list consisting of a subset of the multimedia files 1060. Then the processing unit 100 sends multimedia data of the multimedia files corresponding the play list to the decoding unit 104. The decoding unit 104 decodes the multimedia data and transmits digital signals to the D/A converting unit 103. The D/A converting unit 103 converts the digital signals, thereby yielding analog signals and transmits the analog signals to the audio output unit 102, thus reproducing the multimedia files.
When the search files option 32 such as that shown in FIG. 3 is selected with the input unit 107, the device 10 performs a search files function. Then the processing unit 100 controls the display unit 108 to display a second user interface 40, which is a submenu of the search files option 32 such as that shown in FIG. 3. The second user interface 40, namely a song selection method user interface 40, includes a browse files option 41, a search in local play history option 42, and search in remote play history option 43. When one of the song selection methods is selected according to the instructions from the input unit 107, the processing unit 100 controls the device 10 to perform a file search function, and controls the display unit 108 to display a file search graphical user interface (GUI). The processing unit 100 is also configured for controlling the wireless communication unit 105 to signal the multimedia system 20 to invoke multimedia files of the multimedia system 20 in the storage unit 105 according to files selected.
When the processing unit 100 receives an input instruction corresponding to the browse files option 41, the method choosing module 1000 chooses the browse files option 41, and the list displaying module 1002 acquires the multimedia files 1060 in the storage unit 106 directly and generates a third song choosing interface 50 (see FIG. 5) on the display unit 108. The third song choosing interface 50 includes bibliographic information of the multimedia files, such as song titles, artist(s) name. After the display unit 108 shows the third song choosing interface 50, the song selecting module 1004 receives selecting input instructions generated from the input unit 107 and obtains desired songs. Meanwhile, the device 10 is searched for desired songs on the third song choosing interface 50, by the first word of song title, the first word of artist name, and the like. And then the song selecting module 1004 sends the desired songs to the wireless communication unit 105. The wireless communication unit 105 encodes the desired songs and signals the multimedia system 20 to invoke remote multimedia files. In other cases, the song selecting module 1004 transmits one song to the wireless communication unit 105 one time and the wireless communication unit 105 encodes the song and sends the wireless signal to invoke the song in the multimedia system 20.
When the choose module 1000 chooses the search in local play history option 42, the list displaying module 1002 gains the local play history 1062 in the storage unit 106. The display unit 108 shows a fourth song choosing interface 60 such as that shown in FIG. 6. The fourth song choosing interface 60 includes bibliographic information of the multimedia files, such as song titles, artist(s) name and playing times. After the device 10 plays a multimedia file, the first record module 1006 updates the local play history 1062, thereby adding the playing times of the multimedia file. The fourth song choosing interface 60 displays multimedia data/information in a descending order according to playing times of the songs, such as that shown in FIG. 6. In search in local play history 42, the methods of selecting songs are the same as browse files 41, so the corresponding description is omitted herein.
When the method choosing module 1000 chooses search in remote play history 43, the list displaying module 1002 gains the remote play history 1064 in the storage unit 106. The display unit 108 shows a fifth song choosing interface 70 such as that shown in FIG. 7. The fifth song choosing interface 70 includes bibliographic information of the multimedia files, such as song titles, artist(s) name and selected times. The second record module 1005, connecting with the song selecting module 1004, is configured for updating the remote play history 1064. Once the song selecting module 1004 sends a desired song to the wireless communication unit 105 by a song selection method from browse files 41, search in local play history 42 and search in remote play history 43, the second record module 1005 updates the remote play history 1064, thereby adding the selected times of the multimedia file. The fifth song choosing interface 70 displays multimedia data/information in a descending order according to selected times of the songs such as that shown in FIG. 7. In search in remote play history 33, the methods of selecting songs are the same as browse files 41, so the corresponding description is omitted herein.
