The invention has the advantages of simple scheme, easy implementation, good compatibility and the like.

As shown in Figure 1, the structural block diagram of the IPTV set-top box is shown, and the connection relationship between the upgrade module and other modules in the set-top box is given. The IPTV set top box 100 includes: an upgrade module 101, a network access module 102, a master browser module 103, a play module 104, a digital version management module 105, and a network management module 106. The upgrade module is connected to the upgrade server through the network access module, and relies on the network access module to provide a network connection function, and is configured to complete the upgrade process of the upgrade server. The network access module is connected to the HTTP service module on the upgrade server and is upgraded using the HTTP protocol.

The upgrade module is also responsible for verifying the hardware model and software image during the upgrade of the IPTV set-top box, as well as the judgment of the hardware model of the set-top box, the hardware model file, and the hardware model of the upgrade software image file; When satisfied, the upgrade module uses the upgrade software image file to complete the upgrade process.

The upgrade module interacts with the master browser module, and the interface of the master browser module prompts the user to select and execute.

The specific functions of the above-mentioned play module, digital version management module, and network management module are the same as those of the corresponding modules in the existing IPTV set-top box, and are not described in detail herein.

Based on the interactive network television IPTV set top box and the upgrade server shown in FIG. 1, the upgrade method of the set top box of the present invention includes:

The upgrade server configuration includes a verification value file, a hardware model file, an upgrade rule file, and an upgrade package of one or more upgrade software image files, where the hardware model file and the upgrade software image file have the same hardware model, the verification The value file includes the hardware model file check value and the upgrade software image file check value;

The IPTV set-top box downloads the verification value file from the upgrade server, and then downloads the hardware model file. The set-top box calculates the verification value of the hardware model file, and checks with the hardware model file in the verification value file. If both are consistent, Then continue to download the upgrade rule file and upgrade the software image file;

The IPTV set-top box calculates the verification value of the upgrade software image file, and compares it with the verification value of the upgrade software image file in the verification value file, and determines whether the hardware model of the upgrade software image file is consistent with the hardware model of the hardware model file. If the two are consistent, store the upgrade software image files and use the upgrade software image file to complete the upgrade process.

When the upgrade method is specifically implemented, the definition of the hardware model is first agreed, mainly to define the hardware model file and the hardware model included in the software image itself. Regardless of the box of the same manufacturer or the box of a different manufacturer, the software image of all hardware boxes follows the same convention, in the mirror Like the header definition contains a specific definition of the hardware model. The hardware model file content conventions are: hardware model and hardware version. Through this convention, the association between the hardware model file and the upgrade software image file can be ensured, and the upgrade error of the upgraded software image file of the set-top box hardware can be avoided.

The upgrade server is configured on its upgrade file storage module to include a check value file, a hardware model file, an upgrade rule file, and an upgrade package for each software image file. among them:

The check value file is set to store the check value of other files in the upgrade package, and the corresponding form of the file and the check value is used. One file and the check value respectively occupy one line, and the check value is only valid for the upgrade software image. Does not include the check value of its own check value file and the upgrade rule file in the upgrade package.

The hardware model file is stored in the upgrade path of the upgrade server in encrypted mode to ensure the correctness of the hardware model.

An upgrade rule file, which is set to define specific upgrade rules, such as upgrade when the version number is not equal, upgrade when the version number is greater than the existing version number, and so on.

Each upgrade software image file is a specific upgrade software. The upgrade software image is a separate binary value file. It is a set-top box software. The file contains the set-top box binary application, which can be executed by itself. The upgrade software image itself no longer contains the CRC or ECC check value, and the fifth version of the message digest algorithm (md5) is used to verify the step of judging the verification value of the software image itself, reducing the upgrade time.

When the upgrade is performed, the upgrade module in the IPTV set-top box is responsible for interacting with the upgrade server and verifying the hardware model and software image. The process of upgrading and verifying the hardware model is as follows:

The set-top box requests to download the verification value file under the upgrade path of the upgrade server. After receiving the request, the server responds to the upgrade request of the set-top box, and the set-top box downloads the verification value file.

The upgrade module then requests to download the hardware model file, the upgrade server responds to the download request, and the set-top box downloads the hardware model file successfully. The upgrade module decrypts the hardware model file first, and then calculates the check value of the hardware model file content. If the calculated check value matches the check value of the hardware model in the check value file, the hardware model file is determined. Whether the content is equal to the hardware model definition stored in the set-top box itself.

If equal, the upgrade module then downloads the upgrade rules file, if the upgrade rules allow upgrades and And the user agrees to upgrade, kill other processes in the set-top box, the purpose is to release the memory and ensure the stability of the file system, and then request to download a specific software image file.

After the upgrade of the software image file is successful, the upgrade module first calculates the check value of the upgrade software image file, and determines whether the check value of the upgraded software image file in the check value of the image file and the check value file are calculated. Consistent. If they are consistent, then determine whether the hardware model in the upgrade software image file is consistent with the content of the hardware model file.

The upgrade storage is performed only after the hardware model and checksum of the upgrade software image file are verified successfully.

If the above hardware model judgment and check value are judged to be unequal, the upgrade is exited and the user is friendly to the user: The hardware version software image is incorrect.

After the hardware model judgment and the check value judgment are passed, the software is stored on the storage chip of the set top box. After the upgrade is complete, the set-top box will automatically restart. At this point, the upgrade process is over.

As shown in Figure 2, the file type of the upgrade package included in the upgrade path of the upgrade file storage module of the upgrade server is displayed. The upgrade package includes: a check value file, a hardware model file, an upgrade rule file, and each software image file, where:

(1) The check value file is an md5.txt file, and the md5 (Message Digest Algorithm, the fifth version of the message digest algorithm is a method of encryption and decryption) is used. The format of the md5.txt file is:

Hardware model file md5 value;

Upgrade the software image 1 md5 value;

Upgrade the software image 2 md5 value;

Upgrade software image N md5 value

(2) The hardware model file is used to define the specific hardware model. The hardware model file uses 3DES (Data Encryption Standard).

(3) The upgrade rules file indicates which upgrade conditions will be upgraded. (4) Upgrade the software image, the upgrade software image is a separate binary value file, is the software of the set top box, and the file contains the set top box binary application, which can be executed by itself. The upgrade software image itself no longer contains the CRC or ECC check value, and the md5 checksum is used to eliminate the step of judging the software image itself to reduce the upgrade time.

In this embodiment, the HTTP download protocol is used, and the set top box and the upgrade server must support the HTTP protocol.

S101, the set top box upgrade module first requests to download the md5.txt file.

S102, the server response is upgraded, and 200 OK is returned. The set-top box upgrade module downloads the md5.txt file successfully.

5103, the set top box upgrade module requests to download the hardware model file.

5104, Upgrade server response, return 200 ΟΚ, the set-top box upgrade module downloads the hardware model file successfully.

S105, the upgrade module decrypts the hardware model file, calculates the md5 value of the hardware model file, and compares with the md5 value of the hardware model in the md5.txt file, if the two are equal, the content of the hardware model file is compared with the content of the set top box itself. Is the hardware model consistent?

S106. If both the md5 checksum and the hardware model check pass, the upgrade module requests to download the upgrade rule file.

S107, the upgrade server returns 200 OK. The set-top box upgrade module successfully downloads the upgrade rule file.

5108. If the upgrade rule allows the upgrade and the user agrees to upgrade, the upgrade module of the set top box kills other processes in the set top box and releases the occupied memory.

5109, The upgrade module of the set top box requests to download a specific upgrade software image file.

5110, The upgrade server returns 200 ΟΚ. The upgrade module of the set-top box downloads the upgrade software image file successfully.

5111, after the upgrade software image is successfully downloaded, the upgrade module calculates the md5 value of the upgrade software image file, and compares the value in the md5 file; and compares the upgrade software image file itself. Whether the hardware model matches the content of the hardware model file. If both are equal, the image file is stored on the memory chip. After the storage software image is successful, the upgrade module automatically restarts the set-top box.

In any of the above steps S101 to S111, if the check value or hardware model verification fails, the interface will promptly prompt the user: The hardware version software image is incorrect.
