The present invention relates to an electronic apparatus and more particularly relates to an electronic apparatus interacting with an external device.
Various advanced technologies are developed and electronic devices of huge size in the past can now be made with small size and even more powerful. To satisfy different needs of home and office activities, various devices like set-top boxes and wireless routers are designed and produced. However, when there are more and more devices, it is more and more important to enhance such devices like set-top boxes and wireless routers to have more functions and more flexibility to be more convenient for users.
According to a first embodiment, an electronic apparatus is provided to interact with an external device. The external device is capable of storing electronic documents like photo images, documents, data streams. The electronic apparatus includes a transmission interface, a detector and a processing circuit.
The detector is used for detecting whether the external device is within a predetermined distance. For example, the external device contacts the electronic apparatus or is located within a predetermined distance. In addition, the external device is not wire connected with the electronic apparatus.
The processing circuit automatically establishes a data connection with the external device via the transmission interface according a predetermined setting when the detector detects the external device is located within a predetermined distance. With the data connection, at least one electronic document satisfying the predetermined setting is moved to the electronic apparatus. In addition to the above function, the processing circuit may be added with various additional functions, under different designs, to produce different electronic apparatuses. For example, the processing circuit is added with functions to become a set-top box, a wire or wireless router or a network attached storage (NAS).
In some designs, the data connection includes sending a message to the external device. For example, when the external device like a mobile phone, a tablet computer like iPAD, a camera or a portable hard drive with wireless transmission capability is detected within the predetermined distance, the electronic apparatus sends a network instruction, a push message, a Bluetooth message or a NFC message to inform the external device. When the external device like a mobile phone receives such message, a predetermined operation is triggered. For example, the external device prepares files to be transfer, activates associated processing procedures, e.g. to play multimedia files, establishes a connection with a remote server, and/or communicates with other remote devices.
After the data connection is established between the electronic apparatus and the external device, electronic documents may be transmitted, but such operation is only an example and there are various operations that may be set to be activated on the electronic apparatus and the external device. For example, when the external device is put upon the electronic apparatus, it may be configured for the external device and the electronic apparatus to add, update, and/or delete file documents, to perform data backup on the external device, to perform memory management, to perform disk defragmentation, and/or to charge the external device.
The transmission interface may be designed according to various wire and/or wireless communication standards or various data transmission protocols.
The electronic apparatus may further include a storage and the processing circuit moves the electronic document as mentioned to the storage. The electronic apparatus may further include a plugging interface for a user to plug in or detach the storage. For example, the plugging interface may be a standard USB or Thunderbolt transmission interface for connecting memory cards, thumb drives or various external hard drives. According to different storages or different types of storages plugged via the plugging interface, the processing circuit determines different electronic documents from the external device.
For example, a user may prepare different external USB drives, one for work and another for family photos. In an illustrated example, the external device is a mobile phone and there are work files and family photos in the mobile phone. In this example, the electronic apparatus is plugged with an USB external hard drive for work and when the mobile phone is put near or above the electronic apparatus, the work files are automatically transmitted to the USB external hard drive directly. In another case, when the electronic apparatus is plugged with another USB external hard drive for family photo, and when the mobile phone is put near or above the electronic apparatus, the family photos are automatically transmitted to the USB external hard drive.
The electronic apparatus may provide a setting interface for a user to set the predetermined setting as mentioned above. For example, the predetermined setting may include that when the electronic document is moved to the electronic apparatus, the electronic document is removed from the external device.
Besides, the data connection may be a direct connection between the electronic apparatus and the external device, without via a third device. An alternative way of the data connection is to establish connection between the electronic apparatus and the external device via a wireless router, e.g. via a local network with a Wi-Fi AP (Access Point). Another alternative way of the data connection is to establish a point-to-point (P2P) connection between the electronic apparatus and the external device, e.g. using various hole punching technologies for establishing P2P connection. An embodiment to establish P2P connection includes assigning the electronic apparatus a first identification code and the external device a second identification code. The first identification code and the second identification code are not network addresses. One or more than one server manage the first identification code and the second identification code. The server also helps the electronic apparatus and the external device to establish the data connection in P2P approach. Specifically, the electronic apparatus and the external device retrieve connection data from the server and use such information to establish P2P connection to perform data transmission.
Besides, the predetermined setting may include determining whether the external device stays within the predetermined distance longer than a predetermined time period. If the staying time exceeds the predetermined time period, associated processing is triggered. For different design needs, the electronic apparatus may be configured to interact with different external devices. Each external device may have different identification data. The processing circuit provides data connections of different settings for external devices having different identification data.
