detailed description

Embodiment 1

FIG. 1 is a schematic flowchart of a method for upgrading an upgradeable file according to Embodiment 1. The method of the present embodiment can be performed by an upgradeable device of an upgradeable file, wherein the device can generally be integrated in a digital television integrated machine or a set top box, the method can be applied to the upgrade of files stored in a partition of the memory. As shown in FIG. 1, the method may include the following steps:

Step 110: Acquire and parse the upgradeable file package, and obtain a file description header included in the upgradeable file package and corresponding at least one upgradeable file.

The partition of the memory can be divided into two standard partitions according to the data type of the upgradeable file. Each standard partition may include at least one sub-partition, each sub-partition is configured to store a corresponding upgradeable file, and the file description header includes partition information, and the partition information is a sub-directory for guiding the at least one upgradeable file in the memory. The information stored in the partition.

Exemplarily, the above two standard partitions may include a check partition and a check partition. The files stored in the partition to be verified are files that need to be verified, and it is not necessary to verify that the non-verified files are stored in the partition. The upgradeable file involved in this embodiment may be a binary file, and the memory may be a Flash.

When the set-top box has a bug or a function upgrade during use, the upgradeable file can be upgraded through the Loader.

Before the file upgrade, the set-top box and its upgradeable file package need to be sent to the CA company for authentication. If the certificate is passed, the CA company's signature can be obtained, and then the upgradeable file can be upgraded. Before the CA company certification, Complete the following preparations:

For example, the memory is used as the flash, and the upgradeable file to be upgraded is filled into the corresponding standard partition according to its own data type and the current flash plan size, and then the spliced tool is used to splicing the filled upgradeable file with the file description header. At the same time, other functional partitions in the original Flash (such as Loader or Verify data and other partitions) remain unchanged, forming an upgradeable package. Exemplarily, the partition information in the file description header includes: the total number and size of the sub-partitions to be upgraded, and the address and size of each sub-partition to be upgraded in the corresponding standard partition. Exemplarily, other functional partitions in the original Flash include a hardware configuration file, where the hardware configuration file includes: the total size of each standard partition, the total number of all sub-partitions in the memory, and all sub-partitions to be upgraded. The total number, the address and size of each child partition in the standard partition.

After the upgradeable package is created, the set-top box and its upgradeable package can be sent to CA for certification. Exemplarily, when the CA company performs Loader authentication on the current Flash plan, when the file description header determines that the upgradeable file meets the standard of the hardware configuration file, and the upgradeable file does not affect the set-top box system, it indicates the current Flash plan. Loader passes this certification and can get the signature from CA. The set-top box can upgrade the populated upgradeable files.

FIG. 2 is a schematic structural diagram of a Flash partition according to Embodiment 1; FIG. 2B is a schematic structural diagram of a Flash upgradeable area according to Embodiment 1; As shown in FIG. 2a, the partition Module3-ModuleN (ie, partition 3-partition N) represents an area where file upgrade is possible, and the stored file may be a binary file to be verified or a binary file that does not need to be verified. These two types of files are mixed. For the current Flash Plan A, when the Loader authentication is performed, the address and size of each partition in Module3-ModuleN and whether the information needs to be verified cannot be modified. Therefore, each partition in Module3-ModuleN needs to be authenticated in turn. . As shown in Figure 2b, after the files in Module3-ModuleN are classified into the required check partition (Module_check1) and the check partition (Module_No check2) according to the data type that needs to be checked and not verified, such as Module_sub1 ( That is, the sub-partition 1) and Module_sub2 (ie, sub-partition 2) and Module_subN (ie, sub-partition N) and other sub-partitions store files in the original Module3-ModuleN classified according to the data type. After the standard partition is divided, a file description header is spliced for each standard partition to describe the information of each sub-partition. When performing Loader authentication, CA does not need to know the sub-partition information in each standard partition, and the two standard partitions Module_check1 or Module_No check2 can be authenticated as a whole. For example, the current Flash plan A needs to upgrade the files in the Module_check1 partition, and the size of the file to be upgraded (for example, 10 megabytes) is determined according to the file description header, and does not exceed the total planned check partition in the hardware configuration file (Hwconfig). The size of the device (for example, 20 megabytes) and the detection of the file to be upgraded will not affect the set-top box, the Loader authentication can pass.

After the first Loader authentication is passed, the scalable files stored in each sub-partition of each standard partition can be flexibly configured according to different Flash plans. Illustratively, for Flash Plan B, the number of upgradeable files that need to be upgraded may change relative to Flash Plan A. For example, on the basis of Flash Plan A, a new upgradeable file N (2 megabytes) to be verified is added, so the upgradeable file N needs to be stored in the partition corresponding to Module_check1. In the previous Flash Plan A, the hardware configuration file has been certified by the CA company. For the current upgradeable file in Flash Plan B, you do not need to repeat the authentication because the size of the file to be upgraded in Flash Plan A (10 trillion) ) plus the size of the upgradeable file N (2 megabytes) in Flash Plan B does not exceed the total size of the planned check partition (20 megabytes) in the certified hardware configuration file, so for the current Flash plan The upgradeable file N in B can be upgraded after being signed by the CA company. Therefore, before upgrading the upgradeable file by using the upgrade method of the upgradeable file provided in this embodiment, it is not necessary to obtain the certification of the CA company multiple times, and the cost of the CA company certification is reduced.

After the preparatory work is completed, when the set-top box receives the trigger command for file upgrade, the upgradeable file package can be sent to the set-top box through USB or over-the-air technology (OTA). After receiving the upgradeable file package, the set-top box starts the data parsing process, and obtains the file description header and the corresponding at least one upgradeable file included in the upgradeable file package.

For example, if the set-top box finds that there is no file description header after parsing the upgradeable file package, the upgrade of the upgradeable file is completed according to the file upgrade process provided in the related art.

Step 120: Parse the file description header to obtain partition information.

By parsing the file description header, the total number of sub-partitions to be upgraded, and the address and size of each sub-partition to be upgraded in the corresponding standard partition can be obtained. Therefore, the last storage location of the upgradeable file populated in the upgradeable package in memory can be determined based on the information described in the header.

Step 130: Write at least one upgradeable file into a corresponding partition in the memory according to the partition information.

The file upgrade is to write the file to be upgraded to the corresponding storage area. Since the file to be upgraded is already filled in the upgradeable file package, when the set top box receives the file upgrade instruction, the loader is started, and the original partition is stored according to the address of each sub-partition to be upgraded in the corresponding standard partition. The upgrade of the upgradeable file can be completed by having a file erase and writing the filled upgradeable file to the corresponding standard partition.

The embodiment provides an upgrade method for the upgradeable file. When the upgradeable file in the set-top box memory partition is upgraded, the upgradeable file package is obtained and parsed, and the file description header included in the upgradeable file package is obtained. Corresponding at least one upgradeable file, wherein the partition of the memory is divided into two standard partitions according to the data type of the upgradeable file, and each standard partition includes at least one sub-partition, and each sub-partition is used to store a corresponding one. An upgrade file, the file description header is used to describe corresponding partition information of the at least one upgradeable file in the memory. Since the file storage method provided by the related art does not have a unified standard, after the partition of the memory is divided into two standard partitions, the upgradeable file can be stored in the standard partition according to its data type, and each The standard partitions can calculate their check values uniformly. When the CA company performs the Loader authentication on the upgradeable file package, the technical solution of the present embodiment can authenticate the standard partition as a whole, in a manner that the related technologies provide the authentication for each partition to be upgraded. At the same time, the R&D personnel do not need to calculate the check value for the upgradeable file in turn, and calculate the check value by using the standard partition as a whole. In addition, in each standard partition, it can be flexibly configured according to different Flash plans. a. In the process of CA company authentication, the file description header can determine whether the upgradeable file package in the current Flash plan conforms to the hardware configuration standard in the flash memory. After a Loader authentication, if other Flash plans meet the hardware configuration standards of the Flash memory, other Flash plans do not need to be re-authenticated. CA can sign the upgradeable package by combining the information in the file description header to detect that the upgradeable package does not affect the set-top box. Therefore, by dividing the partition of the memory into two standard partitions, the reusability of the loader can be improved, and the human and material cost can also be reduced. When the set-top box upgrades the upgradeable file package, the file description header and the corresponding at least one upgradeable file included in the upgradeable file package are obtained by obtaining and parsing the upgradeable file package. Obtaining the partition information by parsing the file description header and writing the at least one upgradeable file to a partition corresponding to the memory according to the partition information. At this time, the upgradeable file replaces the original storage partition. The file stored in the file completes the upgrade of the upgradeable file.

Embodiment 2

FIG. 3 is a schematic flowchart of a method for upgrading an upgradeable file provided in Embodiment 2. On the basis of the first embodiment, the second embodiment optimizes the process of writing at least one upgradeable file into the corresponding sub-partition according to the partition information according to the partition information, and the previous process. Referring to FIG. 3, the implementation is performed. Example 2 includes the following steps:

Step 210: Acquire and parse the upgradeable file package, and obtain a file description header included in the upgradeable file package and corresponding at least one upgradeable file.

Step 220: Parse the file description header to obtain partition information.

Step 230: Determine whether the total number of all sub-partitions to be upgraded in the hardware configuration file in the memory is equal to the sum of the total number of sub-partitions to be upgraded in the current two standard partitions. If they are equal, then Step 240 is performed; if not equal, step 250 is performed.

The files stored in each partition of Flash are not all files that need to be upgraded. If some partitions need to be upgraded, the upgradeable files are populated into the corresponding standard partitions during data packaging. Since the file description header contains the total number of sub-partitions to be upgraded, after parsing the file description header, if the sum of the total number of sub-partitions to be upgraded in the current two standard partitions and all the waiting in the hardware configuration file The total number of upgraded sub-partitions is the same (for example, the total number of sub-partitions to be upgraded described in the description header of the check partition is 3, and the sub-partitions to be upgrade described in the description header of the partition are not required to be verified. The total number is 2, and the sum of the total number of sub-partitions to be upgraded in the two standard partitions stored in the hardware configuration file is 5), indicating that the hardware configuration file does not need to be upgraded. If the sum of the total number of sub-partitions to be upgraded in the current two standard partitions is different from the total number of all sub-partitions to be upgraded in the hardware configuration file, it may indicate that the upgrade has been completed in the previous Flash plan. On the basis of the number of files, a new file B to be upgraded is added. Although the file description header contains information such as the address and size of the new file B to be upgraded, there is no new hardware configuration file at this time. The information of the file B to be upgraded is added. Therefore, the hardware configuration file needs to be updated to join the information of the file B to be upgraded.

Step 240: According to the total number of all the sub-partitions to be upgraded in the configuration file and the total number of all the sub-partitions in the hardware configuration file, determine whether it is necessary to upgrade the files of all the sub-partitions, when the files of all the sub-partitions need to be upgraded. Then, step 260 is performed; when it is not necessary to upgrade the files of all the sub-partitions, step 270 is performed.

After upgrading the hardware configuration file, the hardware configuration file contains the total number of sub-partitions to be upgraded. By matching this information with the total number of all sub-partitions, it can be determined whether all sub-partitions in the current Flash need to be upgraded.

Step 250: Replace the information of the file description header with the information of the hardware configuration file to upgrade the hardware configuration file, and continue to step 240.

Step 260: Acquire an address of each sub-partition to be upgraded in the corresponding standard partition according to the partition information, and write all upgradeable files to the sub-partitions in the corresponding standard partition according to the address.

Step 270: Read out the file of the sub-partition that does not need to be upgraded in the memory, calculate the total check value of the files of all the sub-partitions to be upgraded, and continue to step 260.

Exemplarily, if a new file needs to be upgraded, the original stored check value in the Flash partition needs to be updated accordingly after the hardware configuration file is upgraded. After the check value update is completed, the operation of writing the upgradeable file in the address in the corresponding standard partition can be performed.

On the basis of the foregoing embodiment, by updating the hardware configuration file, the set-top box can complete the upgrade of all current upgradeable files in the process of upgrading the upgradeable file, so that the conditional receiving system in the related art is implemented. The bugs were patched and the functionality was improved.
