Hereinafter, the present invention will be described in detail with reference to the accompanying drawings so that those skilled in the art can easily understand and reproduce the present invention.

1 is a diagram illustrating an information processing terminal and a firmware update system of a plurality of host devices using the information processing terminal according to an embodiment of the present invention.

The firmware update system of a plurality of host devices using the information processing terminal according to the present embodiment uses a plurality of host devices 100, for example, electronic devices such as a TV 110, a refrigerator 120, and an audio component 130. Include. Naturally, the electronic device should be provided with an external interface including a USB host module for data communication with the outside. In addition, a USB drive 200 according to an embodiment of the present invention, a computer system 300, a remote server 500, and includes a network 400 for communication with the remote server 500.

The firmware data of each of the plurality of host devices 100 is recorded in the USB drive 200. The latest firmware data is accessed from the remote server 500 through the network 400 by accessing the computer system 300. To be provided. The remote server 500 is most preferably achieved by the manufacturer web server of each host device (100).

As shown in FIG. 2, the USB drive includes a USB interface 210 including at least one data terminal and a ground terminal for data transmission and reception with the host device 100, and the host device 100 is connected to the USB interface. When coupled to 210, the processor 230 for controlling the USB interface 210 for data transmission and reception, and one end of the USB interface 210 including the ground terminal and the data terminal are coupled, the other end is It is connected to the control unit, and includes a path unit 220 for providing a data transmission and reception path with the host device 100 through the USB interface 210, and a memory 240 for providing a storage space. The processor 230 includes a ROM 232 and a RAM 231. The ROM 232 and the RAM 231 are firmware routines or firmware logic for operating a USB drive, not a data storage space of a user. The firmware of the ROM 232 is stored. In addition, when the firmware routine is stored in the ROM 232 and the firmware logic is stored in the setting area of the memory 240, the RAM 231 is temporarily executed by loading the firmware logic by the firmware routine. It is a space. The ROM 232 and the RAM 231 may be implemented in various ways, such as DRAM, SRAM, or the like, such as a Flash type ROM.

The memory 240 of the USB drive 200 includes a first logical region 241 and a second logical region 242 that are logically divided as shown in FIG. 3. The first logical area 241 is an area in which writing and deletion is restricted by an arbitrary user, and the second logical area 242 is an area that can be freely read, written, viewed, and deleted by any user. Such area separation is set at the time of manufacture, and the first logical area 241 is allowed to write and delete only to an authorized user using a separate tool.

As shown in FIG. 4, the first logical area 241 is divided into a hidden area 241a and an executable area 241b.

Since the hidden area 241a has a file structure that the operating system of the computer system 300 does not recognize, only an authorized user who uses a separate tool (for example, an API; Application Program Interface) can read, write, Viewing and deleting is possible, and any user is an area where access (read, write, view and delete) access (ACCESS) itself is not made. Therefore, it is not displayed in the operating system of the computer system 300, for example, Explorer (execution.exe) mounted in the window of Microsoft Corporation, and thus cannot be accessed by any user.

In addition, each of the first logical region 241 and the second logical region 242 may be resized within the total size of the memory 200, and a hidden region of the first logical region 241 may be used. The 241a and the executable region 242b may also be resized within the size of the first logical region 241.

Referring to FIG. 5, firmware data of the plurality of host devices 100, that is, the firmware DB 251 is recorded in the hidden area 241a. Therefore, in order to update the firmware data of the firmware DB 251, the hidden area by the agent software 254 is added to the agent software 254 by adding a part of a function of accessing the hidden area 241a among the API functions. The firmware data of the firmware DB 251 recorded in 241a is updated.

In addition, the hidden area 241a may record VID (Vendor ID, not shown) and PID (Product ID, not shown), which are basic information about the USB drive 200, and ESN used as an authentication tool during external authentication. System data such as (Electronic Serial Number, 252) and the like are recorded.

In addition, in the hidden area 241a, agent software 254 that is executed in the host device 100 and performs various functions such as updating the firmware DB and connecting to the remote server 500 may be stored. It is most preferably stored in 241b and automatically executed in the host device 100 by the autorun 253.

The firmware DB 251 may also be recorded in the executable area 241b, as shown in FIG. This is also done by the agent software 254, which allows updating of firmware data.

The executable area 241b is an area that is recognized as a normal CD-ROM (RW) and is set to be recognized as a virtual device under an operating system of the computer system 300, that is, a window of Microsoft. Therefore, the auto run (Autorun.exe, 253) function is executed in the executable region 241b, and the auto run 253 includes driving command information so that the USB drive 100 is connected to the host device 300. In this case, the application or content stored in the setting location of the memory 200 or the host device 300 may be executed by the autorun 253. 5 and 6, the agent software 254 is most preferably stored in the executable area 241b.

The executable region 241b is displayed as a separate CD-ROM (RW) drive in an operating system of a computer, that is, Microsoft's Windows Explorer (Explorer.exe). Therefore, it is also possible to read and copy the recorded data or contents or application program, but since it is recognized as a virtual CD-ROM drive, the data, contents or application program cannot be deleted. However, this may be done by the agent software 254 or the API.

The agent software 254 runs on the host device 100, but operates with the characteristics of middleware or a platform for the USB drive 200. That is, it is possible to play various applications) and multimedia files, etc. according to a user's input by preset programming logic, and adjust the size between the respective areas according to the addition of API function included in the agent software 254. This would be possible. The agent software 254 provides a GUI to the user, which allows the user to directly manipulate command signals to the agent software through a display module (not shown).

For example, when the size of the stored data of the hidden area 241a increases due to data addition or data update, the size of the hidden area 241a increases, and the size of the stored data of the hidden area 241a decreases due to the update. In this case, the size of the hidden region 241a may be reduced so that the executable region 241b or the second logical region 242 may be used more widely.

Meanwhile, as illustrated in FIG. 7, multimedia content 257 such as a sound source file or a video file may be mounted in the second logical area 242, and the hidden area 241a of the first logical area 241 may be mounted. When digital right management (DRM) is applied to the multimedia content 257, a DRM key 256 for releasing the DRM may be recorded. The multimedia content 257 may be stored in the hidden area 241a. Therefore, since any user is prevented from accessing the multimedia content 257 stored in the hidden area 241a at all, there is no need for a separate DRM process, and the reproduction of the multimedia content 257 is performed only by the agent software 254. By enabling this, there is an advantage to achieving better marketing.

8 to 10 are flowcharts for explaining various operation methods using the USB drive 100 as described above.

Flowchart for

First, referring to FIG. 8, a method of updating firmware data of a plurality of host devices stored in the USB drive 100 is as follows.

In the present embodiment, when the host device is a network-enabled device and the USB drive is connected to a network-capable host device (S11), the agent software stored in the memory of the USB drive is delivered to the host device and executed by the host device. (S12). This is sufficiently possible to be achieved by the autorun 253 of the executable region 241b as described above. As described above, the agent software executed in the host device is connected to the remote server (S13), and an authentication request for performing data communication with the remote server is requested (S14). In the authentication process, the ESN 252 recorded in the hidden area 241a is transmitted to the remote server 500, and the remote server 500 receives the ESN 252 to determine whether the ESN is the authorized device. The process is to authenticate the permission of the data communication.

If authentication is permitted in the step S14, a version check is requested by transmitting the version information of the firmware data of the host device stored in the memory of the USB drive to the remote server, and if the firmware data stored in the memory is the old version, the new version. By transmitting the firmware data, the firmware data of the host device stored in the memory can be updated at all times.

In this case, since a plurality of firmware data, that is, firmware DB exists in the memory of the USB drive, if each host device is a product of the same manufacturer, it can be achieved through one remote server connection and a firmware update process. If the host device is a product of a different manufacturer, the manufacturer's remote server must be connected.

If the authentication is rejected in the authentication request step (S14), the remote server transmits a message of a non-authentication terminal, and the agent software displays this to the user so that only the authorized USB drive can be accessed.

The firmware update process of the host device using the USB drive in which firmware data of the plurality of host devices are stored as described above is illustrated in FIG. 9.

The host device according to the present embodiment may be applied to devices that are not networkable, for example, a TV, a refrigerator, a microwave oven, or the like, but more preferably, may be applied to a device in which a display module is installed.

When the USB drive is connected to the host device (S21), the agent software stored in the memory of the USB drive is delivered to the host device, and is executed by the host device (S22). As described above, the agent software executed in the host device requests authentication for performing data communication with the host device (S24). The authentication process transmits the ESN 252 recorded in the hidden area 241a to the host device 100 (S23), and the host device 100 receives the ESN 252 and transmits the permission of the USB drive. The process of determining whether it is an ESN is to authenticate the permission of data communication.

If authentication is allowed through the above process, the agent software checks the version of the running firmware of the connected host device (S25), and checks the checked firmware version and version information of the firmware data recorded in the memory of the USB drive. In operation S27, when the firmware version is older than the version of the firmware data recorded in the memory of the USB drive, the firmware data of the memory is transmitted to the host device and a command signal for performing the firmware update is output. Therefore, the host device can update the latest firmware by using the firmware data provided by the USB drive.

On the other hand, Figure 10 is a view for explaining the process of playing when the multimedia content in the memory of the USB drive that performs the above function.

When the USB drive is connected to the host device (S31), the agent software stored in the memory of the USB drive is delivered to the host device, and is executed by the host device (S32). As described above, the agent software executed in the host device requests authentication for performing data communication with the host device (S3). In the authentication process, the ESN 252 recorded in the hidden area 241a is transmitted to the host device 100, and the host device 100 determines whether the ESN 252 is transmitted and is the ESN of the USB drive. This is to authenticate the permission of the data communication.

If authentication is permitted in the above step, the agent software determines whether the connected host device is a display device, that is, a device capable of playing multimedia content such as a TV (S34), and if the display device is present, determines whether the multimedia content exists in the memory ( S35). If the multimedia content is present, the user is asked whether to play it (S36), and when the user outputs a corresponding signal to be played through the user interface (not shown), the agent software determines whether the multimedia content is DRM applied ( S37). If the DRM content is applied, it is determined whether there is a DRM key for releasing the DRM in a setting space of a memory, and if so, a signal for releasing and playing the DRM of the multimedia content using the DRM key is output (S40). If there is no key, a non-playback message is output (S39) to induce a user to obtain a legitimate DRM key.

That is, when the host device is a device having a multimedia content playing function, the multimedia device exists in the USB drive so that the USB device can be used for playing the content as well as the firmware update. The multimedia content can be downloaded from the server of the manufacturer, and in this case, DRM is applied to prevent illegal copying to another device, and the DRM key value for releasing it is stored in the memory of the USB drive, and the agent software By releasing the DRM by the user can be used not only for the firmware update but also for multimedia content playback.

In the present embodiment, the firmware is updated by the agent software, and the multimedia content is reproduced by way of example. However, the present invention is not limited thereto.

By extracting the corresponding function of the agent software, a separate operating system is embedded in the operating system of the host device, for example, the latest digital TV, and thus, when the specific USB drive is connected to the operating system, the above-described firmware update and playback of multimedia content are performed. This is possible.

In the detailed description of the present invention, specific embodiments have been described, but various modifications are possible without departing from the scope of the present invention. Therefore, the scope of the present invention should not be limited to the described embodiments, but should be defined not only by the scope of the following claims, but also by the equivalents of the claims.

As described above, the information processing terminal of the present invention can easily upgrade the host device, in particular, a host device that cannot be networked, and can minimize the loss rate by improving the work speed. Therefore, there is an advantage that the after-care costs are reduced.

In particular, since a series of operations for updating the version of the firmware data and performing the update are performed by the agent software of the information processing terminal, the user can easily and conveniently perform the work through the GUI provided by the agent software.

In addition, the information processing terminal of the present invention can be used not only for firmware management but also for playback of multimedia contents, thereby increasing the efficiency.

One embodiment of the present invention described above should not be construed as limiting the technical spirit of the present invention. The protection scope of the present invention is limited only by the matters described in the claims, and those skilled in the art can change and change the technical idea of the present invention in various forms. Therefore, such improvements and modifications will fall within the protection scope of the present invention as long as it will be apparent to those skilled in the art.
