According to the embodiments of the present disclosure, a device that is not provided with a connection interface to a network can be notified of information, or information can be updated and provided to the device.
Hereinafter, embodiments of the present technology will be described with reference to the attached drawings.
The CE device 31 is, for example, a portable music player. The CE device 31 is not provided with a wired or wireless network connection interface. However, the CE device 31 includes an interface such as a drive for attaching or detaching the removable mass storage 32.
The CE device 31 is not limited to the portable media player, but the CE device 31 may be, for example, a digital camera, a television receiver, or other home electric appliances. In other words, the CE device 31 may be any device that is not provided with a wired or wireless network connection interface, but is provided with an interface such as a drive for attaching or detaching the removable mass storage 32.
The removable mass storage 32 is a detachable recording medium. The removable mass storage 32 is a recording medium, for example, a universal serial bus (USB) memory, a memory stick, and a Secure Digital (SD) card.
The network connection device 33 is an electronic device that has an interface for connecting to the Internet 20, and an interface such as a drive for attaching or detaching the removable mass storage 32. The network connection device 33 is, for example, a personal computer.
The distribution server 34 is, for example, a computer that has a relatively high processing ability. The distribution server 34 may be a virtual distribution server using a plurality of computers on the Internet 20.
In the information updating system 10, the CE device 31 that is not provided with a network connection interface can be notified of or provided with new information on the Internet 20. In other words, the CE device 31 can acquire the information from the distribution server 34 through the removable mass storage 32.
Consequently, in the information updating system 10, for example, basic software such as an operating system (OS) or firmware can be updated at appropriate timing.
The information to be recorded in the removable mass storage 32 is associated with a predetermined directory and stored. When the removable mass storage 32 is attached, the CE device 31 reads the information recorded in the predetermined directory. When the removable mass storage 32 is attached, the CE device 31 writes CE device information in a predetermined directory.
The CE device information includes, for example, an ID of the CE device 31, destination information (for example, to Japan, to the United States, or the like) of the CE device 31, and a serial number of the CE device 31. Further, the CE device information includes information for identifying the version of firmware, an application program, contents, and the like, and information about operational states (for example, the frequency of use, and an error occurrence state).
When the removable mass storage 32 is attached, the network connection device 33 accesses the predetermined directory, and reads the above-described CE device information. The network connection device 33 accesses the distribution server 34 through the Internet 20, and instructs the distribution server 34 to retrieve new information that the CE device 31 is notified of.
As will be described below, in order to specify the information to be provided to the CE device, in the CE device information, various attributes and attribute values are specified in advance. The network connection device 33, for example, specifies the information to be provided to the CE device by extracting an attribute value of a predetermined attribute in the CE device information. Then, the network connection device 33 instructs the distribution server 34 to retrieve whether the information is updated, for example.
For example, in a case where the firmware of a new version in the CE device 31 is released, the distribution server 34 transmits a file of the firmware of the new version as a retrieval result to the network connection device 33. The retrieval result is acquired by the network connection device 33 as new information that the CE device 31 is notified of or provided with.
When the network connection device 33 acquires the new information that the CE device 31 is notified of, the network connection device 33 writes the information in a predetermined directory in the removable mass storage 32.
Consequently, for example, if the user detaches the removable mass storage 32 from the CE device 31, and attaches the storage 32 to the network connection device 33, as described above, the firmware of the new version is recorded in the removable mass storage 32. If the user detaches the removable mass storage 32 from the network connection device 33, and attaches the storage 32 to the CE device 31, as described above, the firmware of the new version is read in the CE device 31 and the firmware is updated.
As illustrated in
The CPU 101, the ROM 102, and the RAM 103 are interconnected through a bus 104. To the bus 104, an input/output interface 105 is also connected.
To the input/output interface 105, an input unit 106 such as a keyboard or mouse, and a display such as a liquid crystal display (LCD) are connected. Further, to the input/output interface 105, an output unit 107 such as a speaker, the storage unit 108 such as a hard disk, and a communication unit 109 such as a network interface card, for example, a modem or a LAN card are connected. The communication unit 109 performs communication processing through a network including the Internet 20.
To the input/output interface 105, further, a drive 110 is connected. To the drive 110, the above-mentioned removable mass storage 32 is attached. To the drive 110, a removable medium such as a magnetic disk, an optical disk, a magneto-optical disk, or a semiconductor memory can be attached as appropriate.
In the network connection device 33, when a series of processing operations are executed by software, a program constituting the software is installed from a network such as the Internet 20 or a recording medium such as a removable media.

As illustrated in
The element “ControlCondition” includes an attribute “Variance” and an attribute “ServiceStatus”.
In the attribute “Variance”, a predetermined numerical value is described. The value is used, for example, as a parameter for specifying timing the network connection device 33 accesses the distribution server 34. For example, the numerical value described as the attribute “Variance” is used to specify time. It is possible to prohibit the network connection device 33 from accessing the distribution server 34 to retrieve new information unless the time elapsed from the last writing operation.
In the attribute “ServiceStatus”, a fixed value is described. For example, the fixed value is used as a parameter for setting a status of each product model. For example, the numerical value described as the attribute “ServiceStatus” specifies three types of dates and times, i.e., dates and times of the start of the service, the stop of the service, and the end of the service.
The attribute “ServiceStatus” can be an alphameric character or a symbol other than the fixed value. For example, as the attribute “ServiceStatus”, information about an operational state (for example, the frequency of use, an error occurrence state, a log relating to the operation of the CE device 31, or the like) can be included. For example, the network connection device 33 reads the information on the operational state (the frequency of use, an error occurrence state, or the like) and the log relating to the operation of the CE device 31. When the network connection device 33 accesses the distribution server 34, the network connection device 33 sends the above-described information on the operational state (the log) to the distribution server 34. The distribution server 34 stores the information on the operational state (the log) sent from the network connection device 33 for each CE device.
With the above-described configuration, the distribution server 34 can correct the log information, and analyze the log information about the CE device 31 that is originally not provided with the function of connecting to the Internet 20.
The element “ClientInfo” includes an attribute “Type”, an attribute “Key” and an attribute “Value”.
In the attribute “Type”, the attribute “Key”, and the attribute “Value”, one-byte alphameric characters and one-byte symbol characters of 1 to 128 characters are described respectively.
If “System” is described in the attribute “Type”, for example, Category (the name of the category) is described in the attribute “Key”, and a category ID is described in the attribute “Value”. The category ID is, for example, an identifier of the category relating to the firmware of the CE device 31.
If “content” is described in the attribute “Type”, a URL is described in the attribute “Key” and date and time of the last update is described in the attribute “Value”. Thus, for example, each time contents (for example, concert information of a certain artist) specified by a certain URL are updated, the CE device 31 can be notified of the information.
Similarly,
The element “ClientInfo” in
For example, “system” is described in the attribute “Type” of the element “ClientInfo”, “FirmWareVersion” is described in the attribute “Key”, and the version number of the firmware currently implemented in the CE device 31 is described in the attribute “Value”. Accordingly, when the firmware is updated to a new version, the file of the updated firmware can be provided to the CE device 31.
In another case, for example, “content” is described in the attribute “Type” of the element “ClientInfo”, a URL is described in the attribute “Key”, and date and time of the last update is described in the attribute “Value”. Thus, when the contents are updated, the updated contents can be provided to the CE device 31.
In still another case, for example, if the firmware is updated to a new version, the updated firmware can be provided to a CE device, and to another CE device, not only the firmware, but an updated OS can be provided. In still another case, for example, if contents that can be acquired by accessing a predetermined URL are updated, the updated contents can be provided to the other CE device.
The above-described CE device information is recorded, for example, in a directory of <manufacturer identification number>/<CE device identification number>/<device information> in the removable mass storage 32. The information acquired from the distribution server 34 is recorded, for example, in a directory of <manufacturer identification number>/<CE device identification number>/<updated information> in the removable mass storage 32.
The information illustrated in
Next, in the information updating system 10 in
In step S11, for example, the user attaches the removable mass storage 32 to the CE device 31. In step S12, the CE device 31 accesses the directory of <manufacturer identification number>/<CE device identification number>/<updated information> in the removable mass storage 32, and checks the recorded information. If new updated information has been recorded, the CE device 31 reads the updated information.
In step S13, the CE device 31, for example, accesses the directory of <manufacturer identification number>/<CE device identification number>/<device information> in the removable mass storage 32. In step S14, the CE device 31 writes the CE device information in the directory.
In step S15, for example, the user detaches the removable mass storage 32 from the CE device 31. In step S51, the detached removable mass storage 32 is attached to the network connection device 33.
In step S52, the network connection device 33, for example, accesses the directory of <manufacturer identification number>/<CE device identification number>/<device information> in the removable mass storage 32. In step S53, the network connection device 33 acquires the device information of the CE device 31.
In step S54, the network connection device 33 accesses the distribution server 34 through the Internet 20. Using the CE device information acquired in the processing in step S53, the network connection device 33 instructs the distribution server 34 to retrieve new information that the CE device 31 is notified of.
In step S101, the distribution server 34 receives data relating to the access from the network connection device 33, and executes the retrieval of the new information that the CE device 31 is notified of. For example, if a new version of the firmware of the CE device 31 has been released, the information is acquired as the new information that the CE device 31 is notified of or provided with.
In step S102, the distribution server 34 sends the network connection device 33 the new information (for example, the file of the firmware of the new version) that the CE device 31 is notified of. In step S55, the network connection device 33 receives the information.
In step S56, the network connection device 33, for example, accesses the directory of <manufacturer identification number>/<CE device identification number>/<updated information> in the removable mass storage 32. In step S57, the network connection device 33 writes the information received in step S55 in the directory.
In step S58, for example, the user detaches the removable mass storage 32 from the network connection device 33. In step S16, the detached removable mass storage 32 is attached to the CE device 31.
In step S17, the CE device 31, for example, accesses the directory of <manufacturer identification number>/<CE device identification number>/<updated information> in the removable mass storage 32. In step S18, the CE device 31 reads the information (for example, the file of the firmware of the new version) recorded in the directory. Thus, for example, in the CE device 31, the firmware is automatically updated to a new version.
In the above-described processing, the CE device 31 executes the processing by executing software such as a program using the CPU 131 in the CE device 31. Similarly, in the above-described processing, the network connection device 33 or the distribution server 34 executes the processing by executing software such as a program using the network connection device 33 or the CPU 101 in the distribution server.
As described above, the CE device 31, which is not provided with a network connection interface, is notified of or provided with the new information on the Internet 20.
The series of the processing steps described in the description may be time-sequentially executed in the described order. The processing steps may not be time-sequentially executed, but may be executed in parallel or individually executed.
