In addition, the access servers 130 and 140 can be communicatively coupled to the plurality of electronic devices through the Internet 900. Devices 112-116.

Furthermore, FIG. 2 is a schematic diagram of a data transmission system 200 according to another embodiment of the present invention. Compared to the data transmission system 100 of FIG. 1, the data transmission system 200 in the figure does not include a plurality of access servers 130, 140. In this embodiment, the verification server 120 can be communicatively coupled to the plurality of electronic devices 212-216 through the Internet 900 and the hub 250. In addition, the plurality of electronic devices 212-216 are mutually coupled to each other through the hub 250. In other words, the plurality of electronic devices 212-216 can be coupled through a local network (local lan) connection. limit.

As shown in FIG. 1 and FIG. 2, a plurality of electronic devices 112-116 or 212-216 can be coupled through an Internet (Internet) or a local network (local lan) connection, and each Each of the electronic devices 112-116 or 212-216 can be installed with a group application (APP), and the user uses the electronic devices 112-116 or 212-216 to install the group application to exchange data. Each electronic device with a grouped application has a set of authenticated accounts and secrets. code.

Therefore, the user can log in to multiple different electronic devices through a set of account passwords. When the user logs in the account password, each electronic device automatically connects to an authentication server 120 for authentication. After the electronic devices 112-116 are authenticated, the electronic device 112-116 or 212-216 can form a data transmission group 110 or 210 through a connection method of (Internet) or local area network (local lan). Not limited to this.

In operation, the data transmission method in the data transmission group 110 or 210 is as follows. Please refer to FIG. 1 and FIG. 2 at the same time. In the data transmission group 110 or 210, any electronic device can be used as a transmitting end to transmit its internal files (including: video files, photo files or any other type). The physical file ...) to any other electronic device within the same data transmission group 110 or 210. At the same time, any electronic device in the data transmission group 110 or 210 can also be the receiving end, and can receive files sent from other electronic devices in the same data transmission group 110 or 210. In this case, data sharing and sharing between different electronic devices can be performed through group sharing.

Here, an implementation manner in which a plurality of electronic devices 112-116 are coupled through the Internet (Internet) is first introduced. Referring to FIG. 1 , first, the electronic devices 112 - 116 must be connected to the verification server 120 for identity verification. After verification, the electronic devices 112 - 116 become a data transmission group 110 , wherein the electronic device 116 can serve as At the receiving end, the verification server 120 forwards the command to request the relay data to the remaining electronic devices (for example, the electronic devices 112, 114) in the data transmission group 110, and the remaining electronic devices The device (for example, the electronic devices 112, 114) can convert the physical files (image files, photo files, music files, etc.) to be shared into a relay data (metadta), and then transfer the relay data to the access. The server 130 and the receiving end (for example, the electronic device 116) can obtain the relay data sent by the remaining electronic devices (for example, the electronic devices 112 and 114) from the access server 130.

In this embodiment, the receiving end (for example, the electronic device 116) can obtain the relay data, and the user can view the remaining electronic devices (for example, the electronic device 112, on the screen through the receiving end (for example, the electronic device 116). 114) Meta data of the entity file to be shared, and the relay data is description data associated with the file of these entities.

In this embodiment, one of the remaining electronic devices (for example, the electronic devices 112, 114) can serve as a transmitting end. In practice, the relay data includes: a transmitting end (eg, the electronic device 112) transmitting the entity. The file is sent to a specific access server 130. Therefore, when the transmitting end (for example, the electronic device 112) receives the request sent by the receiving end, the transmitting end (for example, the electronic device 112) uploads the physical file to the access first. The server 130 transmits the physical file to the receiving end (the electronic device 116) via the access server 130. Through this transmission method, users can use multiple electronic devices at the same time, and can automatically connect through the group application (APP), and can easily transfer and share physical files between electronic devices (including: Image file, photo file or music file, etc.).

Secondly, the physical file is transmitted only through the access servers 130 and 140 specified in the data transmission system 100. After the receiving end receives the physical file, the access servers 130 and 140 do not retain the physical files. It will delete the problem of avoiding data leakage.

In this embodiment, the data transmission system 100 can use the free cloud hard disk as the access server 130, 140, thereby achieving cost saving. The aforementioned cloud hard disk may be Google Cloud Hard Drive, Dropbox, SugarSync, SkyDrive, etc. However, various types of cloud hard disks can store a limited file type, and therefore, the transmitting end of the data transmission system 100 can be used to modify the file name of the physical file. The file type of the physical file can be stored by the access server 130, 140.

In the case of file transmission, the user will provide user suggestions based on the characteristics of the file or the size of the cloud space, so that the user can select a currently optimal access server for uploading. The mechanism is as follows. The data transmission system 100 further includes another access server 140, which is communicatively coupled to the electronic devices 112-116, wherein the transmitting end (eg, the electronic device 112) according to the access server 130 and another access server The upload capacity, upload speed, or remaining capacity of 140 may be allowed to determine to transfer the physical file to the access server 130 or another access server 140. The so-called upload capacity allows the user to access the capacity of the server. For example, when using Dropbox as the access server, the user's capacity is 2 GB. This 2 GB is called the allowable upload capacity. The upload speed refers to the speed at which the transmitting end uploads the physical file to the access server. The remaining capacity refers to the capacity of the user provided above, 2 GB. When 1 GB is used, the remaining 1 GB is called the remaining capacity.

Through the above mechanism provided by the embodiment of the present invention, the physical file can be uploaded to the best cloud server, thereby facilitating the user to upload the file.

Here, the multiple electronic devices 212-216 will be introduced through the area. The local lan is implemented as a coupling. Referring to FIG. 2, in another embodiment of the present invention, the electronic device 212 and the electronic device 216 can be coupled through a regional network, which is different from the electronic devices 112-116 coupled through the Internet. The transmission end (for example, the electronic device 212) in the data transmission group 210 directly transmits the physical file to the receiving end (for example, the electronic device 216) without accessing the access server 130, 140. Therefore, In this embodiment, the data transmission system 200 does not need to access the servers 130, 140.

In addition to the file sharing method shown in Figure 1 above, the data transmission system of this case may have another different file sharing and transmission method. To describe in detail the different file sharing and transmission methods, please refer to FIG. 2 . Here, the electronic devices 212 - 216 perform identity verification through the verification server 220 to form a data transmission group 210. One of the electronic devices (for example, the electronic device 216) serves as a connection receiving end, and the connection receiving end sends a request for bidirectional connection to the remaining electronic devices in the data transmission group 210 through the verification server 220 (for example, The electronic device 212), when the remaining electronic device receives the request, establishes a bidirectional connection with the connection receiving end, and at this time, the connection receiving end can request the remaining electronic device to obtain a relay data through the bidirectional connection. In this way, the user can view the file information (image file, photo file or music file, etc.) to be shared by the remaining electronic devices (for example, the electronic device 212) on the screen through the receiving end, but the content that is seen is not The archive information of an entity is only the metadata associated with these entity files.

Subsequently, the remaining electronic device (eg, electronic device 212) acts as a At the transmitting end, the receiving end of the connection requests the physical file associated with the relay data to the transmitting end according to the relay data, and the transmitting end transmits the physical file to the receiving end of the connection.

In this embodiment, when the data transmission system 200 operates on the operating system of the Window, the operating system may limit the transmission of data. For example, if the data transmission between the server and the client is performed, the application of the client is used. When operating in background mode, the server transmits the physical file to the client, and the client is woken up for subsequent data processing. However, when the client wants to transfer the physical file to the server, and the server application operates in the background mode, the server will not be woken up, causing the client to fail to transfer the entity file.

In order to solve the above problems, the present invention proposes that the transmitting end transmits the physical file to the receiving end of the line through the two-way connection mechanism. In detail, when the transmitting end establishes the first connection to the connection receiving end to transmit the physical file to the connection receiving end, the connection receiving end establishes a second connection to the transmitting end, and the first connection and the second connection The line acts as an opposite and one-way data, forming a loop of data streams. In this way, the problem that the material transmission system 200 operates in the Window operating system environment is limited, and the application used by the transmitting end or the receiving end is in the background mode, and the data can be received after receiving the data. Was awakened.

The above embodiments respectively describe the implementation manners of the multiple electronic devices 112-116 or 212-216 through the Internet (Internet) or the local network (local lan) for coupling, and the implementations are respectively implemented. The example exemplarily introduces the common implementation of the above two.

In a common implementation manner in which a plurality of electronic devices are coupled through an Internet and a local lan, in practice, the content of the relay data may include a file name, a directory name, and an archive. At least one of time, file size, label, album name, geographic coordinates, thumbnails, and screenshots. In addition, the above file time may be the file creation time or the latest modification time. For example, for the picture file, the file time may be the shooting time of the picture. The album name refers to the name of the music album to which the music file belongs. The geographic coordinates can be longitude and latitude. For example, some cameras can add latitude and longitude information to the captured image. The above thumbnail is a thumbnail of the image file, and the above screenshot refers to a screenshot of the movie file.

The relay data can be displayed on the screen of the electronic device, and when the relay data is displayed, the display can be separately displayed according to the type of the file (for example, the relay data of the four files of the picture, the movie, the music and the file can be displayed). Displayed by their respective pages), all the relay data can be combined and displayed on the same page. These relayed materials may represent descriptions and descriptions of the physical files to which they belong, for viewing by users of electronic devices.

In an embodiment, after the receiving end obtains the relay data, the remaining electronic device can serve as a transmitting end, and the receiving end can request the physical file related to the relay data from the transmitting end according to the relay data. Furthermore, the receiving end can be used to search for the relay data, and the receiving end can compare the search condition input by the user with the relay data to search for the matching entity file, and prompt the physical file matching the search, and the receiving end The sender needs to match the physical file of the search. The user can input the file name at the receiving end, and then the receiving end compares the relay data of the above file with the file name input by the user, and searches for the physical file whose name matches.

In addition, the user can also input the directory name or enter the tag information at the receiving end, and then the receiving end compares the relay data of the above file with the directory name entered by the user or the entered tag information, and searches for the name of the directory. Or an entity file with this tag information.

In addition, the user can also use the input of the album name at the receiving end to search all the music files of the album. Moreover, the user can also select one of the thumbnails or screenshots of the above-mentioned relay data of the picture file or the video file through the receiving end, such as a face. The receiving end can then compare the thumbnail image with the screenshot and the object selected by the user to search for the image file and/or the video file including the object.

In addition, some cameras can add geographic coordinates, such as latitude and longitude information, to the captured image. The above-mentioned place name search is a conversion between geographic coordinates and address information, so that users can search for image files taken at a certain location by inputting address information. Some services are currently available to the public to convert geographic coordinates and address information, such as the Google map application programming interface (Google map API). The above address information can be a city and street address, such as "The second section of Roosevelt Road, Taipei." The above address information can also be a famous landmark, such as "Taipei 101 Building".

The above-mentioned place name search has two ways. The first type is that the user inputs address information at the receiving end, and the receiving end converts the address information into geographical coordinates, such as longitude and latitude, and searches for the user's picture file. The file itself contains The geographic coordinates correspond to the files of the geographic coordinates resulting from the above conversion. The receiving end can estimate the distance between the geographic coordinates generated by the conversion and the geographic coordinates included in a picture file. If the distance is less than a threshold, the receiving end can determine that the two sets of geographic coordinates are consistent.

The second type of place name search is that the user inputs address information at the receiving end, and the receiving end converts the geographic coordinates of each picture file in the relay data into address information, and searches for the file itself in the user's picture file. The address information matches the file of the address information entered by the user.

Then, the user inputs the time information at the receiving end, and the receiving end converts the time information into a corresponding time or time interval, and in the relay data, searches for the file time to meet the time or time interval generated by the conversion. file. For example, if the time information input by the user is "Christmas", it can be converted to the time of December 25th, and the image file or video file taken on December 25th can be searched. If the time information input by the user is "Spring", it can be converted into a time interval from March 1 to May 31, and the image file or video file taken during this time interval can be searched.

The above file name search, directory name search, tag search, album search, image search, place name search, and time search can be combined to provide a more accurate search. For example, using "spring" to do time search, no matter which year the pictures taken in the spring will be searched, if you use "2008 Spring Taipei" to search, you will only search for pictures taken in Taipei in the spring of 2008.
