invention relates to a method for recovering a system in an electronic device and an electronic device thereof, and more particularly to a method for backing up and updating a system using less storage space. The method of system recovery in the system embedded electronic device and its electric 5 sub-device. [Prior Art] With the development of technology, a variety of system embedded electronic devices have been introduced, such as Set-top Box (STB), Personal Digital Assistant (PDA), Pocket PC ίο ( Pocket PC), mobile phones, laptops, etc., bring convenience to people's lives. Systems in these system-embedded electronic devices are embedded with a system that allows the system's embedded electronics to perform the required functions independently without the need for other devices. For example, as shown in the first figure, the embedded electronic device of the system is a set-top box 1. The interior 15 of the set-top box 1 is provided with a storage unit 11 such as a flash memory card to store the system file 12, so that The TV can access the Internet and play video signals that can only be played on a computer. As shown in the second figure, the system slot 12 may include an operating system (OS), a system database, a face display program, a network service program, a component driver, etc., to implement the software required for the set-top box 1 to operate. Straight 20 is embedded in the storage unit 11. In this way, the set-top box 1 can be independently operated by using the system file 12 without other systems to achieve the effect of being convenient to use. Furthermore, in order to ensure the stability of the system, the storage unit 11 stores a backup system file 13 identical to the system file 12, so that when the set-top box 1 cannot apply the system file 12 to start the system, for example, the system file 12 1282494玖, invention description (2) If the error is generated, it can be directly activated by the standby system broadcast 13 to ensure that the machine j box 1 can be started at any time. After the startup, the backup system file 13 can be used to restore the system file 12. 5 | In addition, as technology advances or bugs in software are found, it is inevitable that the system file 12 needs to be updated. There are a variety of update methods. One of the common update methods is to store the new system building in a system slot server 2, and when the system embedded electronic device needs to update the system file, it can go to the system file server 2 Download the new version of the system to download the system and update the job. In detail, in conjunction with the third figure, in the first step, the system can download the new system file in the system broadcast service 2 through the similar remote access function (R^note A(10)ss Service, RAS). And enter the step after the download is complete. In step 22, the system embedded electronic device will cause the new system to overwrite the original 2 system file 12 to update the system file content with the new system file. 15 times, after the update is completed, step 23 is executed to restart the system with the updated system file 12, that is, reboot. If the startup is successful, then step (24) is followed to update the standby system building 13 to be the same as the updated system slot 12. Conversely, if the system cannot be started with the updated system file 12, then jump to step 25 and start the system with the backup system file 13. Continue to use the system configuration 3 to restore the system file that failed the update. And 7 people started the system by the original system file 逖2. In this way, when the system file i 2 fails to update, the backup system file 13 can still be used to restore, so as to ensure that the system can be started, and then the system 3512 is repaired by itself, and then re-updated 1282494.:......... ........................... 玖, invention description (3), 糸 权 12, ^ ^ assistance from heat maintenance personnel, It achieves the effect of reducing the cost of the manufacturer and the scoop, repairing the cost and ensuring the stability of the system. However, at present, the backup system file 13 is a complete copy of the system file 12, and the storage space occupied by the second and second backup system rights 13 is equivalent to the system floor η, so that the system must be at least twice as long as the system file 12 The capacity of the sub-single 7L 11, for storage of the storage system file 12 and the backup system file. Considering the size, data access, and/or material storage of the embedded electronic device in the system for I. Currently, the storage unit 11 in the embedded electronic device of the system is mostly a flash component, for example CF (c〇mp milk 1〇^(8) card, D_isk Qn MQduie) card. However, the storage of this type is a relatively expensive component compared to other components in the entire system of the system embedded electronic device, and the price of the storage unit 11 is greatly increased as the capacity is increased. Therefore, if the required capacity of the system-embedded electronic clothing unit in the storage unit 11 can be reduced, the hardware cost 15 can be effectively reduced. However, the backup system slot 13 has its existence necessary to cope with the failure of the system slot 12 to be updated or the system slot 12 is damaged. Therefore, the spare system (4) 13 cannot be discarded, so that the capacity of the storage unit S U cannot be effectively reduced. ............, Ά/丁,, % ίι 12 The moment of starting, and if the system can be started, it can use system such as system file: external device such as service 2 to carry out system file 12 Reply or update, the film invented in this case mm(4)t 13 can only contain the necessary systems and programs for the system to open the external device, so that the system can be updated or restored by the external eyebrow to maintain the stability of the system, and Instrument 20 1282494 玖, invention description (4 ) ...,..W.,.ν.νΛ ,:.;, ν; :.;·Μ.::.χ The system building 13 is not the system slot 12 The full copy only contains the part of the system building 12, so the file size of the backup system file 13 can be effective: low, and the cost of storing the soap 7C 11 can be reduced to solve the previous problems. 5 10 15 [Summary of the Invention] Therefore, the object of the present invention is to provide a method for recovering a system (4) in an embedded electronic device and an electronic device thereof, thereby reducing the capacity of the standby system file until it still has It is enough to cope with the function of downloading the update file from the external computer platform, so as to effectively reduce the storage space. Thus, the method of the present invention for recovering a system in an embedded electronic device of the system is characterized in that the embedded electronic device of the system carries a system and a standby system file, and the system file has a system and a plurality of files. Drivers and plurals should be relied upon. (4) Use (10) files to enable (10) embedded electronic devices to be activated and connected - the necessary platform for the computer platform - the program, the computer platform to store - the update file corresponding to the system building, the method includes the following Step·· A) when the money embedded electronic device cannot start the system by the system file, then the backup system is used to start the system and connect to the computer platform to download the update file to update the system file; B) When the (10) file is updated, the system is resumed by the system (4). [Embodiment] The present invention is characterized in that the backup system for the system standard backup includes only the electronic system that is used as the embedded system product in the system broadcast. The necessary line for the start of the farm and the connection to the computer platform and m (4) to the line for the complete 20 1282494 发明, invention description (5) copy, and when the system file is damaged (that is, the system cannot be started) Connecting the computer internet to download an update to reply (or updated) file system, and to respond to is different from the file system backup mode. In order to make the invention easier to understand, it will be explained in an embodiment as shown in the fourth figure. In the embodiment, the embedded electronic device 3 is a set-top box, which enables the television to access the Internet and play video signals that can only be played on the computer. As shown in FIG. 5, the system embedded electronic device 3 of the present embodiment generally has a microprocessor 31, a memory 32, a storage unit 33, and a network card 34. The microprocessor 31 is used to control the system embedded electronic device 3 as a whole. The memory 32 is used for temporarily storing data in the system operation and can be a random access memory (RAM). The storage unit 33 is a flash component for storing non-temporary data such as software, data files, and the like. The network card 34 is a transmission interface and is used to enable data to be uploaded to other devices via the network or to download data to and from the system via the network. In addition, it is known to those skilled in the art that the system embedded electronic device 3 of this example can further include other kinds of transmission interfaces, such as IEEE 1394 35, USB, infrared, Bluetooth, etc., to provide other standard transmission interfaces and The external device communicates, and the system embedded electronic device 3 also includes a display interface card 36 (such as VGA), an MPEG I / Π decoder 20 / encoder 37, CD / VCD ROM (read only memory), and the like. It should not be limited to the description of this example. It should be noted that, as in the fourth figure, the storage unit 33 of this example stores at least one system file 331 and one standby system file 332. Similar to the foregoing second figure, the system file 331 includes an operating system (such as WinCE, Linux), a complex driver 1282494, and a description (6) program (such as a display interface card driver, a network card driver, a 1394 driver, and a PS2 driver). Programs, USB drivers, and multiple applications [Microsoft Foundation Class (MFC), Browser, System Slot Updater, DirectX, Media Player*). Then, the system embedded software 331 is selected to enable the system embedded electronic device 3 to start and connect the necessary system and program core of the external computer platform 4 to form the standby system file 332. In this example, the computer platform 4 is a server that stores an update file corresponding to the system file 331. Since the technology is evolved and errors in the system are found, the update file 10 may contain most versions of the file, and One of the versions is the same as the system file 331. Since the computer platform 4 is a server, the corresponding transmission interface in the system embedded electronic device 3 is the network card 34. As another sixth figure, the backup system file 332 has a sub-set system 38 (Subset OS, which maintains the system startup). Also known as the basic operating system), a network service program set 39 (the 15th program set) and a system file update program 40. The network service program set 39 is a program for connecting the embedded electronic device 3 to the computer platform 4 and allowing the two to transmit data to each other via the network. The driver includes a driver for driving the network card 34, and a The web service program makes the data conform to the network data transmission standard, such as TCPHP. The system file update program 40 is an application for downloading the update file from the 20 computer platform 4. Moreover, the system embedded electronic device 3 has a priority application system file 331 to start the system and set the backup system file 332 to be the second order. Thus, when the system embedded electronic device 3 starts the system, the system file 331 is applied first. The system is booted, and when the system file 331 is unavailable, the system 10 512494 is opened by the backup system file 332, and the invention description (7) ' ' and the system can be turned on and connected according to the program included in the foregoing preparation and file 332. The line to the computer platform 4 is downloaded to correspond to the system 楷 331 (more on the later). In addition, the backup system file 332 is basically set to be a unique item, that is, the user cannot change the content of the injury system file by itself, and 5 ensures that the data of the backup system file 332 is correct and can be supported when the system is unable to boot. Boot up. An embodiment of the method of updating the system file 331 of the present invention will be described in conjunction with the seventh figure in accordance with the foregoing components and relationships. Since the system file 331 is more likely to be damaged when the system 331 is updated, the present embodiment takes the more new system file 331 as an example. First, in step 41, the system embedded electronic device 3 is connected to the latest version of the latest version of the updated building corresponding to the system broadcast 33 i via the network connection, σ upper month self-level σ 4 . Next, in step 42, the system slot 331 is replaced with the broadcast downloaded from the computer platform* to update the version of the system slot 331. 15 and after the update is completed, set H system to restart, so in step U _ , to determine whether the system can be activated by the updated system standard, if it means 'the downloading dragon case is correct, then the end system (four) 331 update operation. On the other hand, if the system fails to start, step 44 is executed, and the standby system broadcast 332 starts the system and connects to the computer platform 4, and then jumps back to step 2 to retrieve the latest version of the file, thus using the foregoing step 41. ～44, the system file 331 can be repeatedly updated until the updated system file can be used to start the system. Thus, when the system file 331 is updated incorrectly, the backup system file 332 can be used to start the system and re-download the file to compensate for the error, and the backup system file 332 is only the _ part of the system file 331 = 1282494 发明, invention description ( 8 .) The system broadcasts a copy of 33i, which is based on the standby system right of the set-top box (as shown in the sixth figure). Compared with the system and the unified slot (such as the second figure), the financial savings can be reduced. The 332's glutinous rice is much smaller than the previous backup system file, which can achieve both the stability and the capacity reduction. 5 Furthermore, although the foregoing embodiment is known to update the system broadcast mode, the present invention can also provide a repair function of the system 楷33ι, which is the season #^$仏 331 due to other factors such as At this time, because the system cannot be started by the system file, the steps 43 , 44 , 41 and M l door 10 10 331 are connected in sequence, as shown in FIG. 10 , and the damaged system is replaced by the method of updating the system. Department 33 is effective. The system is self-repaired. In addition, the foregoing embodiment sets the latest version of the update file corresponding to the system file 331 in the downloading power in step 41. However, the update file stored in the computer platform 4 may include multiple versions. = Security downloads - where - the version will be the same as the system file 331 ^ ^ to call the version of the system is not used to use, update is not smooth, etc., the user may think (four) re-established the original un-updated brother Eight figures are another embodiment of the updating method of the present invention. The difference between the embodiment and the foregoing embodiment is that, when starting the sputum, prior to step 51, the etch water is smashed, and first transmitted to the computer platform 2 to select whether to set the system to be 3 Step 52 is executed to upload the system broadcast 331 / that is, the backup system block 331 to the power 4, 53. Conversely, if you choose to continue with the steps in the future - and choose No Day, skip to step 53. In the step of the illusion 12 1282494 玖, invention description (9) 'users can be selected from all the versions of the log and backup system in the update file corresponding to the system file 331, step 54, start downloading from the computer flat 4 Select the case' and continue with step 5 5 after the download is complete. In step & 55, the system file 331 is updated with the downloaded file, and after the update is completed, step 56 is executed to restart the system to determine whether the updated system file 331 can boot the system. At step 56, if it is determined that the updated system, and then He can start the system, the update operation is ended. Conversely, if the determination in step 56 is negative, step 57 is executed to switch the system system 332 to the system sub-connected computer platform 4, and then jump back to step 53. In this way, in step 53, the user may select to download the backup system previously uploaded in step %, the first version, the other version of the broadcast, for example, the same version of the system slot that was not previously updated; ^, or In the latest version of the slot case, the user is provided with more options and options. In addition to the above embodiments, the stability of the system 15 and the reduction of storage space are provided, and the user is also provided to select the backup source slot and selection. Download different versions of the feature to give users more flexibility to choose from. In summary, in the present invention, the standby system file 20 of the standby function is a part of the system 331 and is matched with the method of the external computer platform 4 to make it available in the system file. Reduce the storage capacity required for the backup system standard 332 == the effect of the fixed and reduced _ quantity, the associated storage system requirements can also be reduced, so it can be used: two clearing 33, to significantly reduce the hardware cost, into The storage unit 33 is degraded and the product market is competitive. 13 1282494 发明, invention description (10) It should be noted that although the system-embedded electronic device 3 of the foregoing embodiment cites a set-top box as an example, it is known to those skilled in the art that it can be applied to other types of systems. The embedded electronic device, such as the personal digital assistant 6 in the ninth figure, the palmtop computer 7, the mobile phone, the notebook computer, etc., and the data between the system embedded electronic device 3 and the computer platform 4 is in addition to the network. Outside the road, other types of transmission interfaces, such as IEEE 1394 35, USB, Bluetooth, infrared, etc., and the computer platform 4 can be different from the server device, such as a personal computer, etc., and thus should not be limited. It is disclosed herein for illustrative purposes. The above is only the preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, that is, the simple equivalent changes and modifications made in accordance with the scope of the present invention and the contents of the description of the invention.
