The target device 110 and the candidate device 120 may respectively support digital home protocols, such as the Digital Living Network Alliance (DLNA) protocol, and be coupled through a home network 130 . The target device 110 may have a specific content 111 for the target device 110 to play. At least one candidate content 121 can be stored in the candidate device 120 . It is reminded that the specific content 111 and the candidate content 121 may be data such as videos, music and images. The management operation corresponding to the specific content 111 and the candidate content 121 will be described later.

FIG. 2 shows an intelligent media playing method according to an embodiment of the present invention. The intelligent media playing method according to the embodiment of the present invention can be applied in a home network with multiple electronic devices.

In step S210, the target device 110 plays the specific content 111, and in step S220, analyzes the specific content according to an analysis technique to obtain key information corresponding to the specific content. It should be noted that, as mentioned above, the specific content 111 may be data such as videos, music and images. In some embodiments, the analysis technology may include an image frame recognition technology, a playback sound recognition technology, and/or a subtitle text recognition technology. Image frame recognition technology can be used to identify images corresponding to specific objects in videos or images. Playing sound recognition technology can be used to identify the name corresponding to a specific object in a video or music. The subtitle text recognition technology can be used to recognize the name of the corresponding specific object in the subtitle of the video. It should be noted that the name of the corresponding object can be presented in the content by text or sound. In other words, the key information corresponding to the specific content 111 may be an image and/or name of an object appearing in the specific content 111 .

Afterwards, in step S230, a dynamic search range is determined from all candidate devices in the home network 130. It must be noted that due to the characteristics of devices moving in the home network, determining the dynamic search range to obtain the current status of the candidate devices in the home network will increase the efficiency of related network transmission. FIG. 3 shows a method for determining a dynamic search range according to an embodiment of the present invention. First, in step S310, a connection confirmation operation is performed between the target device 110 and each candidate device in the home network 130. In step S320, it is determined whether the connection confirmation operation between the corresponding target device 110 and each candidate device is completed. When the connection confirmation operation between the target device 110 and a candidate device is not completed (No in step S320 ), the process ends. When the connection confirmation operation between the target device 110 and a specific candidate device is completed (Yes in step S320), then in step S330, the specific candidate device is added into the dynamic search range.

It should be noted that, in some embodiments, the connection confirmation operation may at least include at least one request and response between the target device and each candidate device. FIG. 4 shows a connection confirmation operation procedure according to an embodiment of the present invention. First, in step S410 , the target device 110 sends a polling request to a candidate device 120 . Corresponding to the polling request, in step S420 , the candidate device 120 sends an alive response to the target device 110 . It should be noted that, in some embodiments, in step S410, the target device 110 may transmit the polling request in a broadcast manner. The candidate device that has received the polling request and is alive will return a liveness response to the target device 110 in step S420 . Corresponding to the keep alive response, in step S430, the target device 110 sends an address query request to the candidate device 120 that sent the keep alive response. After receiving the address query request, in step S440, the candidate device 120 sends an address of itself in the home network to the target device 110 according to the address query request. When the target device 110 obtains the address of the corresponding candidate device 120 , it can connect to the candidate device 120 through the home network according to the address of the candidate device 120 to obtain relevant data, such as the candidate content 121 inside the candidate device 120 . It is reminded that the above-mentioned manner of performing the connection confirmation operation is only an example of the present invention, and the present invention is not limited thereto.

After the dynamic search range is determined, in step S240, the candidate device 120 or the target device 110 in the dynamic search range is used to determine whether the candidate content 121 in the candidate device 120 matches the key information of the corresponding specific content 111. As mentioned above, the key information may be the image and/or name of the object appearing in the corresponding specific content 111 . In some embodiments, the key information for judging whether the candidate content 121 in the candidate device 120 matches the corresponding specific content 111 may be judging whether the candidate content 121 contains the image and/or name corresponding to the object. In addition, in some embodiments, each candidate device may first analyze the internal candidate content according to an analysis technique, so as to obtain key information of the corresponding candidate content, so as to speed up the judgment in step S240. When the candidate content does not match the key information (No in step S240), the process ends. When the candidate content matches the key information (Yes in step S240 ), in step S250 , a prompt is displayed on the target device 110 to remind that the home network 130 has the candidate content. Afterwards, in step S260, it is determined whether a selection corresponding to the prompt is received. When the selection corresponding to the prompt is not received (No in step S260), the process ends. When a selection corresponding to the prompt is received (Yes in step S260 ), in step S270 , the candidate content 121 is acquired by the candidate device 120 through the home network 130 and played.

For example, when the target device plays a video containing an image or name of Taipei 101, the target device may first determine a dynamic search range from the candidate devices in the home network to determine the status of the current candidate devices in the home network. Afterwards, the target device or each candidate device in the dynamic search range can determine whether the candidate content in the candidate device also includes the image or name of Taipei 101. When the candidate content in a specific candidate device includes the image or name of Taipei 101, the target device may display a prompt to remind the candidate content. When the prompt is selected, the target device can connect to the specific candidate device through the home network to obtain and play the candidate content.

FIG. 5 shows an intelligent media playing method according to another embodiment of the present invention. The intelligent media playing method according to the embodiment of the present invention can be applied in a home network with multiple electronic devices.

In step S510, the target device 110 plays the specific content 111, and in step S520, analyzes the specific content according to an analysis technique to obtain key information corresponding to the specific content. Similarly, specific content 111 may be data such as video, music, and images. In some embodiments, the analysis technology may include an image frame recognition technology, a playback sound recognition technology, and/or a subtitle text recognition technology. Image frame recognition technology can be used to identify images corresponding to specific objects in videos or images. Playing sound recognition technology can be used to identify the name corresponding to a specific object in a video or music. The subtitle text recognition technology can be used to recognize the name of the corresponding specific object in the subtitle of the video. It should be noted that the name of the corresponding object can be presented in the content by text or sound. In other words, the key information corresponding to the specific content 111 may be an image and/or name of an object appearing in the specific content 111 . Afterwards, in step S530, the subsidiary information of the corresponding key information is obtained. It should be noted that the present invention does not limit the types of auxiliary information, and any data associated with key information can be defined as auxiliary information. For example, when the key information is the image and/or name of an object appearing in the specific content 111, the auxiliary information may be a piece of location information corresponding to the object, and/or at least one item within a predetermined range corresponding to the location information. The image and/or name of the attached object. It should be noted that, in some embodiments, the location information of the corresponding object and the subordinate objects can be obtained through a map information system or a geographic information system.

After that, in step S540, a dynamic search range is determined from all candidate devices in the home network 130. Similarly, the determination of the dynamic search range and the method of the corresponding connection confirmation operation can be described in the embodiments of FIG. 3 and FIG. 4 respectively. After the dynamic search range is determined, in step S550, the candidate device 120 or the target device 110 in the dynamic search range is used to determine whether the candidate content 121 in the candidate device 120 matches the key information and/or auxiliary information of the corresponding specific content 111. It should be noted that, in some embodiments, judging whether the candidate content 121 in the candidate device 120 conforms to the key information and/or subsidiary information of the corresponding specific content 111 may be to determine whether the candidate content 121 contains the corresponding object and/or subsidiary information. The image and/or name of the object. When the candidate content does not match the key information and the auxiliary information (No in step S550), the process ends. When the candidate content matches the key information and/or subsidiary information (Yes in step S550 ), in step S560 , a prompt is displayed on the target device 110 to remind the home network 130 that the candidate content exists. Afterwards, in step S570, it is determined whether to receive a selection corresponding to the prompt. When the selection corresponding to the prompt is not received (No in step S570), the process ends. When a selection corresponding to the prompt is received (Yes in step S570 ), in step S580 , the candidate device 120 obtains the candidate content 121 through the home network 130 and plays it.

For example, when the target device plays a video containing an image or name of Taipei 101, the target device may first determine a dynamic search range from the candidate devices in the home network to determine the status of the current candidate devices in the home network. Afterwards, the target device or each candidate device in the dynamic search range can determine whether the candidate content in the candidate device also includes the image or name of Taipei 101, and/or other special objects within a predetermined range around Taipei 101, such as the Taipei City Hall images or names of landmarks, etc. When the candidate content in a specific candidate device includes the image or name of Taipei 101, or the image or name of other special objects within a predetermined range around Taipei 101, the target device may display a prompt to remind the candidate content. When the prompt is selected, the target device can connect to the specific candidate device through the home network to obtain and play the candidate content.
