Detailed Description
In order to make the technical problems solved, technical solutions adopted and technical effects achieved by the present invention clearer, the technical solutions of the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Example one
Fig. 1 is a flowchart illustrating an upgrading method for an upgradable file according to an embodiment of the present invention. The method of the present embodiment may be performed by an upgrade apparatus for upgradeable files, wherein the apparatus may be implemented by software and/or hardware, and may be generally integrated in a digital television set-top box, and the method may be applied to upgrade files stored in a partition of a memory of the set-top box. As shown in fig. 1, the method may include the steps of:
s110: and acquiring and analyzing the upgradable file package to obtain a file description header contained in the upgradable file package and at least one corresponding upgradable file.
The partition of the memory can be divided into two standard partitions according to the data type of the scalable files, each standard partition comprises at least one sub-partition, each sub-partition is used for storing the corresponding scalable files, and the file description header is used for describing the partition information corresponding to the at least one scalable file in the memory.
Illustratively, standard partitions include check-needed partitions and check-not-needed partitions. The files stored in the verification partition are all files needing to be verified, and the files stored in the verification partition are not needed to be verified. The file related in the embodiment of the invention is preferably a binary file, and the memory is preferably Flash.
When the set-top box has BUG or needs function upgrade in the using process, the upgradable file can be upgraded through the Loader.
Before the file is upgraded, the set-top box and the upgradable file package thereof need to be sent to a CA company for authentication, if the authentication is passed, the signature of the CA company can be obtained, and then the upgrade of the upgradable file is completed, and before the CA company authenticates, the following preparation work needs to be completed:
and filling a file to be upgraded into a corresponding standard partition according to the data type of the file and the size of the current Flash plan, splicing the filled upgradable file with a file description header by using a splicing tool, and keeping other functional partitions (such as Loader or Verify data and the like) in the original Flash unchanged to form a upgradable file package. Illustratively, 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. Illustratively, other 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, the total number of all sub-partitions to be upgraded, and the address and the size of each sub-partition in the standard partition.
After the upgradeable file package is manufactured, the set-top box and the upgradeable file package thereof can be sent to a CA company for authentication. Illustratively, when the CA company performs Loader authentication on the current Flash plan, if it is determined that the upgradable file meets the standard of the hardware configuration file according to the file description header and the upgradable file does not affect the set-top box system, it indicates that the Loader of the current Flash plan passes this authentication and can obtain the signature granted by the CA company, and the set-top box can upgrade the filled upgradable file.
Specifically, fig. 2a is a schematic structural diagram of a Flash partition according to an embodiment of the present invention; fig. 2b is a schematic structural diagram of classified Flash scalable areas according to an embodiment of the present invention. As shown in fig. 2a, the area Module3-ModuleN represents an area where file upgrade can be performed, where the stored file may be a binary file that needs to be checked or a binary file that does not need to be checked, and the two types of files are arranged in a mixed manner. For the current Flash plan a, when Loader authentication is performed, information such as the address, the size, whether verification is needed, and the like of each partition in Module3-ModuleN cannot be modified, and therefore, each partition in Module3-ModuleN needs to be sequentially authenticated. As shown in FIG. 2b, after dividing the files in the Module3-ModuleN into check partition (Module _ check1) and check-free partition (Module _ No check2) according to the data types that need to be checked and need not be checked, the files in the original Module3-ModuleN classified according to the data types are stored in the sub-partitions such as Module _ sub1 and Module _ sub 2. After dividing the standard partition, a file description header needs to be spliced for each standard partition to describe information of each sub-partition. When performing Loader authentication, the CA company does not need to know the information of child partitions in each standard partition, and authenticates the two standard partitions, i.e., Module _ check1 or Module _ No check2, as a whole, for example, it is a file in the Module _ check1 area that needs to be upgraded by the current Flash plan a, and it is determined according to the file description header that the size (e.g., 10 megabytes) of the file to be upgraded does not exceed the total size (e.g., 20 megabytes) of the partition to be checked planned in the hardware configuration file (Hwconfig), and when detecting that the file to be upgraded does not affect the set-top box, Loader authentication can pass.
After the first Loader authentication is passed, the upgradable files stored in each sub-partition of each standard partition can be flexibly configured according to different Flash plans. For example, for Flash plan B, the number of files to be upgraded may change relative to Flash plan a. For example, an upgrade file N (2 mb in size) of a partition to be checked is newly added on the basis of Flash plan a, and therefore, the upgrade file N needs to be stored in an area corresponding to Module _ check 1. As the hardware configuration file in the last Flash plan A is authenticated by the CA company, and the upgrading file in the current Flash plan B does not need to be repeatedly authenticated, because the sum of the size (10 million) of the upgrading file in the Flash plan A and the size (2 million) of the upgrading file N in the Flash plan B does not exceed the total size (20 million) of the planned partition needing to be checked in the authenticated hardware configuration file, the file N to be upgraded in the current Flash plan B can be upgraded after the signature of the CA company is obtained. Therefore, before the upgradable file is upgraded by using the upgrading method of the upgradable file provided by the embodiment of the invention, the certification of the CA company does not need to be obtained for many times, and the certification cost is reduced.
After the preparation work is completed, when the set-top box receives a trigger instruction for file upgrade, the upgradeable file package may be sent to the set-top box in the form of USB or OTA (Over-the-Air Technology), etc. After receiving the upgradable file package, the set-top box immediately starts a data analysis process to obtain a file description header contained in the upgradable file package and at least one corresponding upgradable file.
Illustratively, after the set-top box parses the upgradable file package, if it is found that the file description header does not exist, the set-top box completes file upgrading according to a file upgrading process provided in the prior art.
S120: and analyzing the file description header to acquire partition information.
By analyzing the file description header, the total number of the sub-partitions to be upgraded and the address and the size of each sub-partition to be upgraded in the corresponding standard partition can be obtained. Thus, the last storage location of the scalable files filled in the scalable file package can be determined from the information described in the file header.
S130: and writing at least one upgradable file into the corresponding partition of the memory according to the partition information.
The file upgrading is to write the file to be upgraded into the corresponding storage area. Because the upgradable file package is filled with the files to be upgraded, after the set-top box receives a file upgrading instruction, the Loader is started, the original files of the storage partitions are erased according to the addresses of the sub-partitions to be upgraded in the corresponding standard partitions, and the filled upgradable files are written into the corresponding standard partitions, so that the upgrading of the upgradable files can be completed.
The embodiment of the invention provides an upgrading method of upgradable files, which is characterized in that when upgradable files in a set top box memory partition are upgraded, an upgradable file package is obtained and analyzed, and a file description header and at least one corresponding upgradable file contained in the upgradable file package are obtained, wherein the partition of the memory is divided into two standard partitions according to the data type of the upgradable files, each standard partition comprises at least one sub-partition, each sub-partition is used for storing the corresponding upgradable files, and the file description header is used for describing the partition information corresponding to the at least one upgradable file in the memory. Because the file storage mode provided by the prior art does not have a uniform standard, the partition of the memory is divided into two standard partitions, the upgradable file can be correspondingly stored into the standard partitions according to the data types of the upgradable file, and the check value of each standard partition can be uniformly calculated. When the CA company performs Loader authentication on the upgradable file package, compared with the mode of sequentially authenticating each partition to be upgraded provided by the prior art, the technical scheme of the embodiment of the invention can authenticate the standard partition as a whole. Meanwhile, research and development personnel do not need to calculate check values of the upgradable files in sequence, the check values of the standard partitions are calculated as a whole, and in addition, the upgradable files can be flexibly configured in each standard partition according to different Flash plans. In the process of authentication of a CA company, whether the upgradable file package in the current Flash plan meets the hardware configuration standard of a Flash memory can be judged through a file description header. After one Loader authentication, if other Flash plans do not exceed the hardware configuration standard of the Flash memory, the other Flash plans do not need repeated authentication. The CA company can sign the upgradable file package when detecting that the upgradable file package can not affect the set-top box by combining the information of the file description header. Therefore, the partition of the memory is divided into two standard partitions, so that the reusability of the Loader can be improved, and the cost of manpower and material resources can be reduced. When the set-top box upgrades the upgradable file package, the file description header contained in the upgradable file package and the corresponding at least one upgradable file are obtained by acquiring and analyzing the upgradable file package. Acquiring the partition information by analyzing the file description header; and writing the at least one upgradable file into the partition corresponding to the memory according to the partition information, wherein the upgradable file replaces the file stored in the original memory partition, and the upgrading of the file is completed.
Example two
Fig. 3 is a flowchart illustrating an upgrading method for an upgradable file according to a second embodiment of the present invention. In the second embodiment, on the basis of the first embodiment, the process of the step "writing at least one upgradable file into the partition corresponding to the memory according to the partition information" and the previous process are optimized, and referring to fig. 3, the second embodiment of the present invention specifically includes the following steps:
s210: and acquiring and analyzing the upgradable file package to obtain a file description header contained in the upgradable file package and at least one corresponding upgradable file.
S220: and analyzing the file description header to acquire partition information.
S230: judging whether the total number of all sub-partitions to be upgraded in the hardware configuration file is matched with the sum of the total number of the sub-partitions to be upgraded in the current two standard partitions, if so, executing the step S240; otherwise, step S250 is executed.
It should be noted that 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 upgradable files are filled into the corresponding standard partitions in the data packaging process. Since the file description header contains the total number of the sub-partitions to be upgraded, after the file description header is analyzed, if the sum of the total number of the sub-partitions to be upgraded in the two current standard partitions is the same as the total number of all the sub-partitions to be upgraded in the hardware configuration file (for example, the total number of the sub-partitions to be upgraded described in the description header of the partition to be verified is 3, the total number of the sub-partitions to be upgraded described in the description header of the partition not to be verified is 2, and the sum of the total number of the sub-partitions to be upgraded in the two standard partitions stored in the hardware configuration file is 5), it indicates that the hardware configuration file does not need to be upgraded; if the sum of the total number of the sub-partitions to be upgraded in the two current standard partitions is different from the total number of all the sub-partitions to be upgraded in the hardware configuration file, it can be shown here that a new file B to be upgraded is added on the basis of the number of files already upgraded in the previous Flash plan, and although the file description header contains information such as the address and the size of the new file B to be upgraded, the newly added information of the file B to be upgraded does not exist in the hardware configuration file at this time, so the hardware configuration file needs to be updated to add the information of the file B to be upgraded.
S240: judging whether the operation of upgrading the files of all the sub-partitions is needed or not 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, if so, executing the step S260; otherwise, step S270 is executed.
After the hardware configuration file is upgraded, the hardware configuration file contains the total number information of all the sub-partitions to be upgraded. By matching the information with the total number of all the sub-partitions, whether all the sub-partitions in the current Flash need to be upgraded can be judged.
S250: the information of the file description header is substituted for the information of the hardware configuration file to upgrade the hardware configuration file, and the step S240 is continuously performed.
S260: and acquiring the address of each sub-partition to be upgraded in the corresponding standard partition according to the partition information, and writing all the upgradable files into the sub-partitions in the corresponding standard partition according to the address.
S270: reading the files of the sub-partitions which do not need to be upgraded in the memory, calculating the total check value of the files of all the sub-partitions to be upgraded, and continuing to execute the step S260.
For example, if a file to be upgraded is newly added, after the hardware configuration file is upgraded, the check value originally stored in the Flash partition also needs to be updated correspondingly. After the updating of the check value is completed, the operation of writing the upgradable file in the address in the corresponding standard partition can be executed.
On the basis of the above embodiment, by updating the hardware configuration file, the set-top box can complete the upgrade of all currently upgradable files in the file upgrade process, so that the bug of the conditional access system is repaired, or the function of the conditional access system is further improved.
