Referring to fig. 2, fig. 2 is a schematic flow chart of an embodiment of a method for verifying burning data according to the present invention, and the method is applied to a detection device, the detection device is in communication connection with a set top box, and the method for verifying burning data includes:
step S10, sending data to be burned to a set top box, wherein the set top box burns the burning data to a memory after receiving the burning data;
in a conventional recording scheme, a set top box without a card CA (Conditional Access, CA for short) plays a recording file after the set top box is turned on to determine whether the recording of the set top box is correct. When the burning method is used, a professional technician is required to start the set top box to play the burning file after burning is finished to check whether the burning file has errors, and then the check result is input into a test tool, so that the efficiency of checking the burning file is low.
The detection equipment determines whether the data to be burned is successfully burned into the set top box or not by carrying out data transmission and information interaction with the set top box.
The data to be burned is the data which is sent to the set top box for burning through the detection equipment.
The preset position is a position where the set top box stores the burning data into the set top box after the set top box acquires the data to be burned.
In the application, the detection device is provided with a plurality of detection interfaces, can establish wired connection with the set top box through each detection interface, and sends data to be burned to the set top box through the wired connection.
It will be appreciated that during production, no corresponding hardware address is present in the set-top box. The hardware address is pasted in the shell of the set top box, optionally, the hardware address can be displayed in a two-dimensional code mode, therefore, the hardware address of the set top box can be obtained by scanning the two-dimensional code outside the set top box through the scanning device in the application, and the hardware address of the set top box is sent to the detection equipment so that the detection equipment can obtain the preset data of the set top box. And the hardware address is burned to the set-top box during burning so as to directly read the hardware address of the set-top box during subsequent maintenance of the set-top box.
The set top box receives the data to be burned and burns the data to be burned into the memory.
In this embodiment, when the data for establishing the connection by the detection device includes the set top box, the data burning between different set top boxes can be realized through the detection device. For example, when the detection device is connected to the set top box a and the set top box B at the same time, the data in the set top box a may be sent to the set top box B, and after the set top box B receives the data sent by the detection device, the received data is burned into the internal storage space in the set top box B.
Step S20, reading the burned target burning data of the set top box, wherein the target burning data is the area data of the burned burning data of the set top box;
and after the set top box finishes burning the data to be burned, sending the burning finish prompt information to the set top box. And when the detection equipment receives the prompt information, reading the target burning data burnt by the set top box. After the detection device sends the data to be burned to the set top box, the set top box burns the data to be burned to a preset position (for example, internal storage), performs CRC (cyclic redundancy check) on the burnt data according to a protocol with the detection device to obtain target burning data, and stores the target burning data as a part of the burnt data in the set top box.
It is understood that the target burning data is a value calculated for the original partition file using a specified algorithm. There are many methods for checking data, including parity Check, BCC (block Check library) Check, CRC (Cyclic Redundancy Check) Check, and so on. The purpose of data verification is to guarantee the integrity of the original partition file, that is, to guarantee the integrity of data.
Reading the target burning data at the detection equipment, determining whether the target burning data is matched with preset data, determining that the first verification is successful when the target burning data is matched with the preset data, acquiring the version information fed back by the set top box, and performing second verification on the burning data.
Step S30, acquiring version information of the burning data of the set-top box when the target burning data is matched with preset data;
and step S40, determining the burning result of the set top box according to the verification result of the version information.
In this embodiment, after the set top box successfully burns the data to be burnt, the set top box is restarted, if the version information of the burning data corresponding to the set top box can be normally acquired and is matched with the preset version information, it indicates that the burning of the data to be burnt is correct, and if the acquired version information is not matched with the preset version information or is burnt to an incorrect version, the burning of the set top box fails.
In this embodiment, the detection device sends data to be burned to a set top box, wherein the set top box burns the data to be burned to a preset position after receiving the data to be burned, reads burned target burning data of the set top box, wherein the target burning data is verification data of the burning data burned by the set top box, acquires version information of the burning data of the set top box when the target burning data is matched with the preset data, and determines a burning result of the set top box according to a verification result of the version information. Whether the set top box successfully carries out burning is determined by detecting the data communication mode between the equipment and the set top box, and the burning efficiency of the set top box is improved.
Referring to fig. 3, fig. 3 is a flowchart illustrating an embodiment of a method for verifying burning data according to the present invention, wherein the step of reading the burned target burning data of the set top box includes, based on the first embodiment
Step S21, determining the storage position of the target burning data;
step S22, reading the target burning data in the burning data according to the storage location.
In this embodiment, it is first determined that after the set top box completes programming, the programmed data is verified to obtain target programming data, and the target programming data is stored in a preset storage location.
Optionally, in this embodiment, after the set top box completes burning the data to be burned and burns the target burning data to the preset storage location, the information that burning has been completed is sent to the detection device. And sending the storage address of the target burning data to the detection equipment. And after the detection equipment acquires the storage address sent by the set top box, reading the target burning data according to the storage address.
When the target burning data is matched with preset data, the step of acquiring the version information of the burning data of the set top box comprises the following steps:
step S31, comparing the target burning data with the preset burning data;
step S32, when the comparison is consistent, determining that the target burning data is matched with the preset data;
and step S33, acquiring the version information of the burning data of the set top box.
In this embodiment, after the target burning data is obtained, the target burning data is compared with the preset burning data.
It can be understood that, in the embodiment of the present application, the preset burning data is verification data corresponding to the burning data.
And comparing the target burning data with the preset burning data, determining that the target burning data is matched with the preset data when the target burning data is consistent with the preset burning data, and executing the step of acquiring the version information of the burning data of the set top box.
In this embodiment, the detection device determines the target burning data obtained according to the burning data in the set top box by obtaining the storage position of the target burning data, can quickly determine the target burning data, and matches the target burning data with the preset data, so that the speed of checking the burning data is increased.
Referring to fig. 4, fig. 4 is a schematic flow chart of an embodiment of the present application.
After the detection device scans an SN code on the set-top box through a scanning device, for example, a scanning gun, obtains a Media Access Control Address (physical Address) of the set-top box according to the SN code (optionally, the MAC Address can be displayed above a shell of the set-top box in a two-dimensional code form), the detection device finds a corresponding set-top box according to a port, reads a chip from the set-top box, finds CA-related data matched with the set-top box one by one according to the chip, binds the CA-related data with the SN/MAC, and burns the CA-related data into the set-top box. After burning, reading part of data needing to be verified from the set-top box, and performing first round verification, wherein if verification fails, the PC end prompts that burning fails. And after the burning is successful, the set top box is restarted, the set top box end automatically carries out the second round of verification on the burned CA data file through an algorithm, and after the verification is successful, a CA data burning normal prompt is displayed at the set top box end. In the whole process, the Irdeto test stream is not needed to help verify the burned CA data, and a specific verification implementation method will be described in detail below.
(1) Verification method of CA Data IFCP Data (burning Data)
In the irdeo card-free CA burning, a plurality of Data files need to be burned, wherein the burned CA Data file (IFCP Data) normally cannot judge whether the burning is correct without playing an irdeo test stream. For example, if the IFCP Data of the a set-top box is burned into the B set-top box, and the burning abnormality cannot be seen by the set-top box (the IFCP Data version number can be normally displayed after the set-top box is turned on) under the condition that the burning of other CA Data files is correct, the IFCP Data error can be prompted only when the Irdeto test stream or the official stream is played.
Therefore, according to the CA Data file provided by Irdeto, the CRC check file of the IFCP Data can be generated in advance according to the rule, the CRC is linked with the Chipid, and the CRC corresponding to the IFCP Data of the set top box can be found according to the Chipid in the production stage. After the CA Data is produced and written, comparing the CRC of IFCP Data in the read set-top box with the CRC of IFCP Data generated in advance, and indicating that the Data is written correctly. And restarting after the set top box is programmed, if the IFCP Data is programmed correctly, the set top box can read out the version of the IFCP Data, and the correctness of the programmed CA Data is confirmed by matching whether the version number is consistent with the preset version number and combining with the IFCP Data CRC. The whole IFCP Data checking method can be realized.
(2) CA data random number checking method
In the production process of Irdeto card-free CA, random numbers of two fields need to be burned, and the two random numbers are finally bound with a set top box and related to descrambling. However, according to the Irdeto official production scheme, the two random numbers are randomly generated during production, so that, as long as some reason occurs during production, the CA data needs to be rewritten and rewritten, the two data will be changed continuously, which is inconvenient to maintain, and the basis for checking the two random numbers during production cannot be provided. In addition, there is a use scenario, for example, if a set-top box that has applied for formal authorization needs to rewrite CA data for some reason, if the scheme that the Irdeto official generates a random number during production is adopted, the random number that has been bound to the set-top box cannot be burned into the set-top box, and thus the set-top box cannot descramble normally after the CA data is burned.
In order to solve the problem, before production, according to a CA data file (a CA data file contains a chip list of a main chip of the set-top box) provided by Irdeto, a random number is generated according to the chip, the random number is bound with the chip, and the corresponding random number is found according to the chip during production and is burnt into the set-top box. Therefore, the random number of each set top box becomes fixed, the requirement of the Irdeto random number is met, and meanwhile, a basis is provided for checking the random number during production. After the production is finished, whether the burned random number is correct or not can be analyzed according to the production report.
(3) CA data configuration file checking method
And after the set-top box successfully burns the CA data configuration file, the CA library can be normally loaded after the set-top box is restarted, otherwise, the loading fails. And judging whether the CA data configuration file is correctly burned or not according to the read CA library version number and matching with the known version information in advance.
(4) CA data file SecureCore verification method
After the set top box successfully records the CA data configuration file, the SystemID and the CA data file SecureCore, the set top box is restarted, if the SecureCore version number can be normally obtained and is matched with the previously known version number, the SecureCore recording is correct, and if the set top box fails to record or records to an incorrect SecureCore, the correct SecureCore version number cannot be obtained.
In this embodiment, the detection device sends data to be burned to a set top box, wherein the set top box burns the data to be burned to a preset position after receiving the data to be burned, reads burned target burning data of the set top box, wherein the target burning data is verification data of the burning data burned by the set top box, acquires version information of the burning data of the set top box when the target burning data is matched with the preset data, and determines a burning result of the set top box according to a verification result of the version information. Whether the set top box successfully carries out burning is determined by detecting the data communication mode between the equipment and the set top box, and the burning efficiency of the set top box is improved.
