Understanding that these drawings depict only several embodiments in accordance with the disclosure and are, therefore, not to be considered limiting of its scope, the disclosure will be described with additional specificity and detail through use of the accompanying drawings.
[0011] FIG. 1 illustrates a schematic diagram of a system for resuming playback of a multimedia file according to one embodiment of the present disclosure; and
[0012] FIG. 2 illustrates a schematic flow chart of a method for resuming playback of a multimedia file according to one embodiment of the present disclosure.
DETAILED DESCRIPTION
[0013] In the following detailed description, reference is made to the accompanying drawings, which form a part hereof. In the drawings, similar symbols typically identify similar components, unless context dictates otherwise. The illustrative embodiments described in the detailed description, drawings, and claims are not meant to be limiting. Other embodiments may be utilized, and other changes may be made, without departing from the spirit or scope of the subject matter presented here. It will be readily understood that the aspects of the present disclosure, as generally described herein, and illustrated in the Figures, can be arranged, substituted, combined, and designed in a wide variety of different configurations, all of which are explicitly contemplated and make part of this disclosure.
[0014] FIG. 1 illustrates a schematic diagram of a system 10 including a plurality of electronic devices connected to a network according to one embodiment of the present disclosure. The system 10 includes a first electronic device 100, a second electronic device 200, and a third electronic device 300, which are connected to each other through a network, such that they can communicate with each other. In some embodiments, the network may be a peer to peer network.
[0015] Referring to FIG. 1, the first electronic device 100 includes a processing device 101 and a communication device 102. In some embodiments, the processing device 101 may be a central processing unit. In some embodiments, the processing device 101 may be combination of a plurality of computing devices such as combination of a CPU and a GPU (graphic processing unit), combination of a CPU and an APU (audio processing unit), or combination of a CPU, a GPU, and an APU etc. The communication device 102 is adapted for communicating with other electronic devices connected to the network. In some embodiments, the communication device 102 may be a network adapter.
[0016] The second electronic device 200 also includes a processing device 201 and a communication device 202.
[0017] In some embodiments, the system 10 may include more electronic devices.
[0018] FIG. 2 illustrates a flow chart of a method S10 for resuming playback of a multimedia file based on the system 10 according to one embodiment of the present disclosure.
[0019] In S 101, the first electronic device 100 receives a user instruction of pausing playback of a multimedia file when the multimedia file is played by the first electronic device 100. In some embodiments, the multimedia file may be a video file, an audio file, or a text file such as an electronic newspaper or an electronic novel. In some embodiments, the user instruction may be generating information of where playback of the multimedia file to be resumed from, without pausing playback of the multimedia file.
[0020] In SI 02, upon receipt of the user instruction of pausing playback of the multimedia file, the processing device 101 controls the first electronic device 100 to generate information of where playback of the multimedia file to be resumed from. In some embodiments, the information may include a time point where playback of the multimedia file to be resumed from, such as 5th second of a song. In some embodiments, the information may include a frame number of the multimedia file where playback of the multimedia file to be resumed from, such as 30th frame of a song.
[0021] In SI 03, the processing device 101 controls the communication device 102 to send the information to electronic devices on a synchronization list through the network. In some embodiments, the synchronization list may be defined by a user e.g. a group of electronic devices connected to the network may be defined. Information of where playback of a multimedia file to be resumed from generated on one electronic device of the group may be sent to other electronic devices of the group, and may be used by these electronic devices to resume playback of the multimedia file. In one embodiment, the first electronic device 100, the second electronic device 200, and the third electronic device 300 are on the synchronization list, and the information shall be sent to the second electronic device 200, and the third electronic device 300.
[0022] In S201, if the second electronic device 200 is live when the first electronic device 100 sends out the information, the communication device 202 of the second electronic device 200 receives the information.
[0023] In S202, the processing device 201 controls the second electronic device 200 to check whether it contains the multimedia file, if not, the processing device 201 generates a request for the multimedia file, and controls the communication device 202 to send the request to the first electronic device 100. In some embodiments, the processing device 201 may control the communication device 202 to send the request to all devices on the synchronization list.
[0024] In SI 04, the communication device 102 receives the request from the second electronic device 200, and in S105, the processing device 101 controls the communication device 102 to transmit the multimedia file to the second electronic device 200. Accordingly, in S203, the communication device 202 receives the multimedia file.
[0025] If the second electronic device 200 is powered off when the first electronic device 100 sends out the information in SI 03, when the second electronic device 200 is accessed or powered on, in S204, the processing device 201 controls the communication device 202 to send a notification that it is accessed to the first electronic device 100. In some embodiments, the second electronic device 200 may send the notification to all electronic devices on the synchronization list.
[0026] In SI 06, the communication device 102 receives the notification. In some embodiments, if the communication device 202 receives the information in S201, the processing device 201 may control the second electronic device 200 to generate an acknowledgement that it receives the information, and may control the communication device 202 to send the acknowledgement to the first electronic device 100. If the communication device 102 does not receive the acknowledgement, and receives the notification, the processing device 101 may control the communication device 102 to resend the information to the second electronic device 200 in SI 07. Accordingly, in S205, the communication device 202 receives the information.
[0027] In S206, the processing device 201 controls the second electronic device 200 to prompt a user to input an instruction of whether resume playback of the multimedia file. In S207, the second electronic device 200 receives a user instruction of resuming playback of the multimedia file. In S208, the processing device 201 controls the second electronic device 200 to resume playback of the multimedia file using the received information.
[0028] If the first electronic device 100 is powered off when the second electronic device 200 sends out the request for the multimedia file or the notification that it is accessed, the second electronic device 200 may obtain the information and the multimedia file from other electronic devices connected to the network.
[0029] In some embodiments, the second electronic device 200 may receive multiple pieces of information each of which indicates where playback of a corresponding multimedia file to be resumed from. A user may select to resume playback of one multimedia file on the second electronic device 200.
[0030] It should be noted that the order of the operations described above may be changed.
[0031] While various aspects and embodiments have been disclosed herein, other aspects and embodiments will be apparent to those skilled in the art. The various aspects and embodiments disclosed herein are for purposes of illustration and are not intended to be limiting, with the true scope and spirit being indicated by the following claims.
