Problems solved by technology

[0005] The process of generating the upgrade file in the existing technical solution is to directly generate the upgrade file after the TS adds the header information. When the upgrade file is illegally tampered with, the receiver cannot judge the identity of the sender or determine the legitimacy of the upgrade file from the upgrade file; On the other hand, the upgrade process only verifies the TS header information. If it passes the verification, it will be saved and updated, and the security and legality of the data cannot be determined. If the set-top box upgrades unsafe data, the set-top box will be attacked

Embodiment Construction

[0057] The embodiment of the present application provides a data processing method, a set-top box upgrading method, a terminal and a set-top box, which are used for security upgrading of the set-top box.

[0058] The set-top box can receive digital TV broadcasting programs, and also has functions of various digital TV broadcasting and interactive multimedia applications. With the continuous increase of technical updates and new services, it is often necessary to upgrade the set-top box software.

[0059] see figure 1 , a schematic diagram of an embodiment of the data processing method in the embodiment of the present application.

[0060] The terminal generates a TS from the plain text of each module to be upgraded. The module to be upgraded can be a boot screen module, an application program module, etc., and the TS Header date is added such as the software, hardware version number and the module to be upgraded. Wait for the upgrade information to generate an upgrade file, ...

Abstract

The embodiment of the application discloses a data processing method, a set top box (STB) upgrade method, a terminal and the STB. The data processing method is used for the safety upgrade of the STB,and can guarantee that an upgrade file passing the check is not tampered and is legal by adding the signature check in the digital signature and upgrade process. The method disclosed by the embodimentof the application comprises the following steps: the terminal acquires a to-be-upgraded module; the terminal generates a transmission stream according to the module; the terminal adds upgrade information at the head of the TS; and the terminal adds the digital signature for the TS to obtain the upgrade file.

Description

technical field [0001] The application relates to the field of set-top boxes, in particular to a data processing method, a method for upgrading a set-top box, a terminal and a set-top box. Background technique [0002] A set-top box is a network terminal device that connects a TV set to an external signal source. In addition to receiving digital TV broadcast programs, the set-top box also has a variety of digital TV broadcast and interactive multimedia application functions. With the continuous increase of technical updates and new services, it is very necessary to upgrade the set-top box software. [0003] The existing method for obtaining the upgrade file is that the terminal generates a transport stream (TS, transport stream) from the plaintext of each module to be upgraded, such as a boot screen module and an application program module, and adds such as software at the head of the TS. , hardware version number and upgrade information such as modules to be upgraded, and ...
