The resource sharing system 100 includes a first wireless access point 110, an electronic device 120, an electronic device 130, a first electronic device 140 and a playing device 150. Wherein, the electronic device 120 and electronic device 130 may be electronic devices with wireless network communication interface and audio files playing requirement, such as desktop computer, tablet computer, laptop computer, smart phone, PDA. The first electronic device 140 may be a desktop computer, a tablet computer, a laptop computer, a cell phone, a smart phone, a PDA and a television or any electronic devices having a screen. Wherein, the first electronic device 140 has a communication unit 142, configured to search a valid wireless access point in a specific area. The playing device 150 may be a sound bar with wireless connecting function, configured to receive and broadcast desired audio signals from the electronic device 120, the electronic device 130 and the first electronic device 140.
  • FIG. 1B is a functional block diagram of a system for resource sharing according to another embodiment of the present invention. Except that the playing device 150 further includes a receiving unit 152 and a control unit 154, the system for resource sharing in FIG. 1B is similar to the system for resource sharing of FIG. 1A. The receiving unit 152 has a wireless network communication interface, for receiving and transmitting signal packages. The control unit 154 is coupled with receiving unit 152, configured to establish a connection between the playing device 150 and other electronic devices. The control unit 154 may be implemented with a hardware circuit framework, a software or a firmware. Overall, the resource sharing system 100 is configured to share playing resource of the playing device 150 with multiple electronic devices (such as the electronic device 120 and the electronic device 130). After the playing device 150 is connected to the first wireless access point 110, multiple electronic devices are able to connect the first wireless access point 110 via wireless network, and then access to playing resources of the playing device 150.
  • FIG. 2A is a flow chart of a method for resource sharing according to an embodiment of the present invention. Please referring to FIG. 1B and FIG. 2A together, the communication unit 142 of the first electronic device 140 searches a valid wireless access point in an area and obtains the first wireless access point 110 upon searching (step S210). Next, the first electronic device 140 is connected to the first wireless access point 110, and a first ID data of the first wireless access point 110 is obtained (step S220). Wherein the first ID data includes a first SSID (service set identifier) and a first WPA (WiFi protected access). Wherein the first SSID is a MAC address (media access control address) of the first wireless access point, and a first encoding rule is existed in between the first SSID and the first WPA.
  • FIG. 1C is a functional block diagram of the first electronic device 140 of the system for resource sharing according to an embodiment of the present invention. The first electronic device 140 may be a television device. As shown in FIG. 1C, a display unit 145 is a screen of the television device, an operating interface 147 is displayed on the display unit 145. After step S220, users may execute a specific command via the operating interface 147. For example, playing resource sharing function of the playing device 150 may be easily activate by users via a dialog on the operating interface 147 which displays a “Activate resource sharing for the playing device?” message. In the present embodiment, user may select an option on the dialog via a remote controller. If a “Yes” button displayed on the screen is selected by users, the first ID data is then sent to the playing device 150 via the first electronic device 140 (step S230).
  • Next, after the first ID data is received by the receiving unit 152 of the playing device 150, the first ID data is then sent to the first wireless access point 110. An authorization and a connection is performed between the control unit 154 and the wireless access point 110 (step S240). After the connection is established, the electronic device 120 or the electronic device 130 in the area is then connected to the first wireless access point 110 (step S250). The electronic device 120 or the electronic device 130 is now able to access playing resource of the playing device 150 via the connection between the first wireless access point 110 and the playing device 150 (step S260).
  • FIG. 2B is a flow chart of a method for resource sharing according to another embodiment of the present invention. Except a comparing process of an advanced authorization between step S230 and step S240, the flow chart in FIG. 2B is similar to the flow chart in FIG. 2A. If a result of the operating operation is matched, the playing device 150 is then started to connect the first wireless access point 110. In the present embodiment, a second ID data is stored in the playing device 150. The second ID data includes a second SSID and a second WPA, and a second encoding rule is existed in between the second SSID and the second WPA. Wherein, the second SSID is a MAC address of the playing device 150.
  • The encoding rules mentioned above are described in more detail below. For example, the first SSID is a 6 byte (48 bit) MAC address of the network card with a 6 sets of hexadecimal numbers. In this example, assumed that the MAC address is 68:10:01:10:12:78. Next, perform a specific encoding using decimal addition to the 6 sets of hexadecimal numbers. For example, create a WPA with a sequence of numbers arranged in following order: the sum of the first 2 sets of numbers (i.e. 68+10), followed by the sum of the next 2 sets of numbers (i.e. 01+10) and the sum of the last 2 sets of numbers (i.e. 12+78). As a result, the WPA is 781190. Namely, such arrangement is the first encoding rule of the present embodiment. The encoding rule between the first SSID and the first WPA is not limited by said arrangement, and a different setup may be applied based on the demand.
  • In other words, the control unit 154 of the playing device 150 may compare and determine whether the first encoding rule of the first wireless access point 110 is matched to the second encoding rule of the playing device 150 (step S235). If the result of the comparing process is matched, proceed to the operation of step S240. The remaining steps in FIG. 2B are the same with steps in FIG. 2A, so it will not be described herein.
  • In view of above, the present invention provides a system and a method for resource sharing and a playing device thereof. The system and the method for resource sharing allow a specific electronic device to establish a connection between the playing device and the first wireless access point. This mechanism allows other electronic devices in the area to connect the first wireless access point so the electronic devices in the area may access playing resource of the playing device via the connection between the first wireless access point and the playing device. For example, with the above-mention mechanism, users may easily connect multiple electronic devices in their family with an authorized playing device via wireless network connection.
  • Although the invention has been described with reference to the above embodiments, it will be apparent to one of the ordinary skill in the art that modifications to the described embodiment may be made without departing from the spirit of the invention. Accordingly, the scope of the invention will be defined by the attached claims not by the above detailed descriptions.
