[Previous technology] With the development of science and technology, a variety of system-embedded electronic devices have been introduced, such as Set-top Box (STB), Personal Digital Assistant (PDA) 15 (PDA), Pocket PC (Pocket PC), mobile phones, notebook computers, etc., bring all kinds of convenience to people's lives. Most of the storage units in these electronic electronic devices in the system are embedded with an image, so that the W electronic device in the system can perform the required functions independently without matching with other devices. For example, as shown in the figure, the electronic device in this system is a set-top box.] Inside the set-top box 1, there is a storage unit U such as a flash memory card to store the image file 12, so that the TV Can access the Internet and play video signals that could only be played on a computer. As shown in the second figure, the image inspection 12 may include the operating system (〇 AtlngSystem, ⑹, system database, daytime display

Network service programs, component drivers, etc., so that the software required by the set-top box U is directly lost in the health storage unit u. In this way, the on-board path uses the image slot 12 to operate independently without the need for other systems to achieve the convenience of use. The helmet is removed to ensure the stability of the system by trial and error. Storage 70 ^ stores a spare image 13 which is the same as the image file 丨 2 for the system's embedded electronics | 1Unable to apply the image file 12 Kai 20 200411371 When the system is running, such as image broadcast 12 error, you can directly start the system from-backup == like 檑 13 to ensure that the discrete electronic devices in the system can be started at any time and start Later, the backup image structure 13 can be used to restore the image: slot 12 〇 In addition, due to technical progress or software bugs (bugs) found, etc., the image slot 12 will inevitably need to be updated. There are currently many Method, the medium update method is to store the new version of the image eaves in an image slot feeder 2, and when the system's embedded electronic device 12, ίο 15 2〇 ^ new image slot, you can go to the image Slot server 2 downloads a new version to update the image file. Toda Niu sudden force Γ, in conjunction with the third picture, first in ν 21, the embedded electronic mine type electronic device 1 can be stored by similar remote take

Complete copy, so the storage μ occupied by the backup image building 13 is equivalent to the image file 12, so that the system = type electronic device i needs at least twice the capacity of the image slot to store the previous n for storage image playback 12 and injury. Use image storage. In order to consider the size, data access speed, and data retention of the embedded electronic device in the system, most of the storage unit u of the embedded electronic device in the Muyu system is a Fiash component, such as CFCCompact Flash) ^. D〇M (Disk On Module)-^ 〇, compared with the other 7L parts in the whole system, this type of inventory unit n is a more expensive component, and with the increase of capacity The price of the storage unit 11 has increased significantly. Therefore, if the system can be embedded electronic devices! If the capacity required for medium storage is reduced, the hardware cost can be effectively reduced. However, the spare image slot 13 is necessary to cope with the failed update of the image file 12 or the image slot 12 is damaged. Therefore, the backup image file 13 cannot be discarded, so that the required capacity of the storage unit 11 cannot be effectively reduced. However, the backup image 13 is used to support the moment when the system cannot be started by the image slot 12, and if the system can be started, the external device such as the image slot feed service 2 can be used to perform the mapping_12 reply or update. The inventor of the present case considers that the backup map 13 may only include the system and the necessary systems for the system to start and the external system, so that it can be accessed through external devices 厶 V7LM · 丄 丄 J / 丄

'5 2 new or reply Yingqian 12' to maintain the stability of the system, and because the backup like L 13 is not a full copy of the image slot 12, and only contains the-part of the image gift 12, so the backup image 檑 13 file The size can be effectively reduced and the cost of the storage unit 11 can also be reduced to solve the problems in the past. [Summary of the Invention] 10 • Therefore, an object of the present invention is to provide a method and an electronic device for recovering a funeral casket in the system and an electronic device, which is to reduce the valley for a spare two-image file to a level sufficient to imitate it.

In order to make the present invention easier to understand, it will be described with the embodiment shown in FIG. In this embodiment, the 3 built-in set-top box of the system is a video signal that enables the TV to access the Internet and play. Yu Tunyue 15 The micro-embedded system in this example has roughly -microprocessor pirate 31, -memory 32, -storage unit 33, and -net 34. The microprocessor M is used to control the system electronic device 3, and the memory 32 is used to temporarily store the operating data and may be a random access memory (Random ACcess Memory, RAM). Storage unit 33 is a flash component used to store non-temporary data, such as software data items and so on. The network card 34 is a transmission interface and is used to upload data to other devices via the network or to download data to the embedded electronic device 3 of the system. In addition, those skilled in the art should know that the embedded electronic device 3 of the system in this example may further include other types of transmission interfaces, such as IEEE 1394 35, RF, infrared, Bluetooth, etc., to provide other standard transmission interfaces and Communication with external devices, and the embedded electronic device 3 in the system also includes a display interface card 36 (such as VGA), an MpEGi / π decoder / encoding module 37, CD / VCD ROM (read-only memory), etc. It should be limited by the description of this example. It should be noted that, as shown in the fourth figure, the storage unit 33 of this example stores at least one image file 331 and a core image file 332. Similar to the previous second figure, 20 200411371

Image slot 331 contains operating system (such as WinCE, Linux), plural drivers (such as graphics card driver, network card driver, U 94 driver, PS2 driver, USB driver), and multiple applications [ Microsoft Class Library (Microsoft — Class, MFC), Liu ίο 15 browser (Browser), image update program, Directx, multimedia player (Media Player)]. Then, from the image file 331, the system embedded electronic device 3 is selected to be activated and connected—a necessary system and program core of the external health work platform 4 to form a core image file 332. In this example, the work level σ 4 is a server that stores an update file corresponding to the image file 331. 'As the technology evolves and errors are found in the system, the update target may contain multiple versions of «, and Among them, the versions are the same: the image 4 field 331 is the server 4 of the work platform, and the corresponding transmission interface in the electronic device 3 in the system is the network card 34. As shown in the sixth figure, the core image file 332 has- The child collection system that maintains the system startup is 38 Lion Post 0S, also known as the basic operating system),-network service program collection 39 (the first program collection) and-the image slot update process < 4〇 (that is, the first application program) . The network service program collection 39 is a program that enables the embedded electronic device 3 in the system to be connected to the work platform 4 and allows the two to transmit data to each other via the network. The program includes a driver and a network card 34, and a network. The road service is to make the data conform to the network data transmission standard, such as% Tcp / ip.

In this way, when the "electronic device 3" starts the system, it will first apply the image: 10 20 200411371

331 to start the system, and then when the image file 331 is unavailable, the core image file 332 is used to start the system, and according to the private type included in the aforementioned core image file 332, the system can be booted and connected to the work platform 4, Download the update file corresponding to the image file 331 (to be described later). In addition, the core image file 332 is basically read-only, that is, the user cannot change the content of the core image file 332 to ensure that the data of the core image file 332 is correct. It can always support booting when the image file 331 fails to boot. 10 15 According to the aforementioned components and interrelationships, and with the seventh figure, an embodiment of the method for updating the image file 331 of the present invention will be described. Since the image slot 331 is easily damaged when the image slot 331 is updated, the update image file 331 is taken as an example in this embodiment. Since there are no steps, no, many, and several types of devices are installed and "you connect to the work platform 4 via the Internet and select the latest version of the file in the update file corresponding to the image target 331 to download. Next, in step 42, replace the image file 331 with the self-defense file * to update the version 33 of Ying :. After the update is complete and set the system to restart, so at step 4, == can you determine whether the updated image can be used to update the system? If yes, it means that the downloaded file is correct, then the image file is terminated, such as: industry. Conversely, if the system fails to start, execute step M, start the system by ^ image standard 332 and connect to the platform of Weizuo 4. Go to step 42 to re-acquire the latest version of the slot case, so use the aforementioned / 41 44 ' The image slot 331 can be updated repeatedly until the updated image: = is available to boot the system. In this way, when the image file is updated incorrectly, the kernel image slot 332 can be used to start the system and re-download the slot case = fill 20. The column surface i ...: Ty: :::: ~ 10 10 20 20 200411371 error, And the core image slot 332 is only a copy of the image slot 33i-not a copy of the image 4 field 331. The core image building of the set-top box (as shown in the sixth figure) is compared with the image target (as shown in the second picture) as For example, it can reduce the size, so the capacity of the core image is much smaller than the previous backup image, which can achieve the effect of reducing the capacity while taking into account the stability of the system. Furthermore, although the foregoing embodiment is described by updating the image structure, a person skilled in the art will know that the present invention can also provide a repair function when the image slot 331 is destroyed, that is, the # image file 331 due to other factors such as When the machine crashes, at this time, because the image slot 331 cannot be started at this time, the aforementioned steps 43, 44, 41, and 42 will be performed in order to replace the destroyed image broadcast 331 by updating the image slot 331. The system achieves the effect of self-repairing. In addition, in the foregoing embodiment, the download work level is set in step 41. △ 4: The latest version of the update file corresponding to the image file 331. However, in fact, it is stored in the work platform. Will contain multiple versions of the slot, 'for downloading' among them-the version will be the same as the version of the image slot 331 and there are factors such as the unusable use of the new version of the image standard, the update is not smooth, etc., users may want The original image slot is restored before being updated, so as shown in Figure 8 is another embodiment of the update method of the present invention. This embodiment is different from the previous embodiment in that when starting to update the image: Yes, before step 51, the user can choose whether to upgrade the image slot to the work platform as described above. 4 The temporary storage option is YES, then the system embedded electronic Install / 4 will perform step 52 to upload the image file 331 to the work level a *, that is, the injury image Tan 331 on the work platform ", and then continue to perform: step 12 200411371 Conversely, if the right choice is no, skip to step …, Use Thai 3 in step 53 and all versions in the update file corresponding to image file 331 are too μ. After image _—, perform step ",: = 5 10 15 20 -v; rT ^, execute Step 56, new update of the second case :::: Elephant slot 331, and whether the system can be started after the update is completed. In ^ break, the new image file can start Yutong # ... right to judge the updated mapping system and connect the work level λ. Instead, start from the core image building 332 μ, the user can choose to download m 53 ° In this way, you can choose the image of the step, the version of the other version of the slot you uploaded in step 52, or the version of the image that was not updated before. Therefore, this implementation =, to provide users with more stability and reduce storage "in addition to the original embodiment of the system taking into account the original image", and also provides users with the option to back up and return ^ different functions In order to allow users to have more flexible space to choose from. "" In summary, in the present invention, the method of "using the core image of the backup function to upload files, so that two copies are matched with the work from the outside ... The premise that the image right can be effectively updated or restored == the storage capacity required by the image slot 332, which is reachable =: the effect of stabilizing and reducing the healthy storage capacity, and the associated high-cost storage for the core image slot 332 The requirement of unit 33 can also be reduced, so a lower capacity storage unit 33 13 200411371 can be used.
