DETAILED DESCRIPTION

Embodiments of the present disclosure are now described in detail, with reference to the accompanying drawings.

Referring to FIG. 1, a multimedia file playing system 1 includes at least one portable device 10 and a set-top box 20. The set-top box 20 downloads the at least one multimedia file from a network server 30 according to user input, and transmits the at least one multimedia file to the at least one portable device 10 to display/play. For simplicity, one portable device 10 is employed to illustrate the present disclosure. The portable device 10 may be a mobile phone, a wrist worn device, or an E-book.

Referring to FIG. 2, the portable device 10 includes an input unit 11, a first storage unit 12, a first processor 13, a first wireless communication unit 14, a display unit 15, and an audio playing unit 16.

The input unit 11 is for users to input at least one keyword for searching for multimedia files. The first storage unit 12 stores a format supported by the portable device 10. In the embodiment, the format includes a resolution and a coding format.

The first processor 13 is configured to generate a play request signal including at least one input keyword in response to the input from the input unit 11. In addition, transmit the play request signal including the at least one keyword and the stored format to the set-top box 20 through the first wireless communication unit 14, to request the set-top box 20 to search desired multimedia files which satisfy the format supported by the portable device 10. The first processor 13 receives at least one multimedia file from the set-top box 20 if the set-top box 20 searches the at least one multimedia file in the network server 30, and determines the number of the at least one multimedia file is one or more than one. In this embodiment, the at least one multimedia file received from the set-top box 20 is streaming media, thus the set-top box 20 can transmit already downloaded portion of the at least one multimedia file to the device 10 to display/play during the downloading of the at least one searched multimedia file. If only one multimedia file is received, the first processor 13 controls the display unit 15 and/or the audio playing unit 16 to display/play the multimedia file. If more than one multimedia files are received, the first processor 13 controls the display unit 15 to display the multimedia files in a multi-widow mode for users to preview and select. The first processor 13 further transmits a selecting signal including an identifying code for identifying the selected multimedia file to the set-top box 20 in response to the user selection, to direct the set-top box 20 to continue downloading the selected multimedia file, and stop downloading the other searched multimedia files.

The set-top box 20 includes a network interface 21, a second wireless communication unit 22, a second processor 23, and a second storage unit 24.

The network interface 21 communicates the set-top box 20 with the network server 30. The second wireless communication unit 22 communicates with the first wireless communication unit 14. In the embodiment, the second wireless communication unit 22 and the first wireless communication unit 14 may include any one or more of a BLUETOOTH unit, an infrared unit, a USB interface, and a WI-FI unit, for example.

The second processor 23 receives the play request signal and the format, and searches in the network server 30 according to the format and the input keyword included in the play request signal. If at least one multimedia file is found, the second processor 23 starts to simultaneously download the at least one multimedia file and transmits the already downloaded portion of the at least one multimedia file to the portable device 10 during the downloading of the at least one multimedia file. In the embodiment, the downloaded at least one multimedia file is streaming media. When a selecting signal is received through the second wireless communication unit 22, the second processor 23 continues downloading the multimedia file corresponding to the selected multimedia file and stops downloading the other found multimedia files according to the selecting signal.

Referring to FIG. 3, a flowchart of a multimedia file playing method implemented in the multimedia file playing system 1 in accordance with an exemplary embodiment is illustrated.

In step S301, the first processor 13 transmits a play request signal including at least one keyword in response to the input from the input unit 11 and the stored format to the set-top box 20 through the first wireless communication unit 14 and the second communication unit 22.

In step S302, the second processor 23 searches the network server 30 according to the input keyword included in the play request signal and the format to find at least one desired multimedia file. While simultaneously downloading the at least one found multimedia file from the network server 30, and transmitting the already downloaded portion of the at least one multimedia file to the portable device 10 during the downloading of the at least one found multimedia file. In the embodiment, the at least one multimedia file is streaming media.

In step S303, the first processor 13 determines the number of the received multimedia file is one or more than one. If one multimedia file is received, the procedure goes to step S304. Otherwise, the procedure goes to step S305.

In step S304, the first processor 13 displays/plays the multimedia file.

In step S305, the first processor 13 displays the multimedia files in the multi-window mode for users to preview and select.

In step S306, the first processor 13 displays/plays the selected multimedia file, and transmits a selected signal including an identifying code for identifying the selected multimedia file to the set-top box 20.

In step S307, the second processor 23 continues downloading the multimedia file corresponding to the selected multimedia file and stops downloading the other multimedia files according to selecting signal.

Although the present disclosure has been specifically described on the basis of the exemplary embodiment thereof, the disclosure is not to be construed as being limited thereto. Various changes or modifications may be made to the embodiment without departing from the scope and spirit of the disclosure.
