[0018] see figure 1 , which is a flow chart of the method for upgrading software of a terminal device provided in the first embodiment. First, step 110 is executed to start the upgrade process. Specifically, a mobile storage device may be connected to the terminal device first, and a predetermined key or combination of keys on the terminal device may be pressed to start an upgrade program built in the terminal device. Here, the terminal device may be, for example, a digital TV, a set-top box, a router, a home gateway, and the like. The terminal device may include a main control chip, a first storage, a second storage and a USB interface. Wherein the first memory is the main memory, which has relatively large space, and is used for storing the underlying system software and user data of the digital TV. User data includes, for example, installed software, plug-ins, usage records, and registration information. The second memory is used to store a small amount of information t...

[0028] refer to figure 2 The second embodiment provides a software upgrade method for terminal equipment, which is similar to the software upgrade method of the first embodiment, except that the intermediate version has a password verification function in addition to the data backup function. Correspondingly, a step 210 is also included between step 140 and step 150, verifying the input password. Only after the password verification is passed can the data backup and upgrade operations continue, otherwise the upgrade process ends. Here, the password can be obtained by directly using the hardware information of the terminal device or by using a certain algorithm to calculate the above hardware information. The hardware information may be, for example, the MAC address of the network card, the product serial number of the terminal device, and the like. These hardware information are generally unique, that is to say, a password is valid only for this terminal.

[0031] refer to image 3 , the third embodiment provides a software upgrade method for terminal equipment, which is similar to the software upgrade method of the first embodiment, the difference is that a step 310 is also included between step 120 and step 130 to determine the intermediate version Whether the upgrade file of the intermediate version is valid, the subsequent step 130 is performed only when the upgrade file of the intermediate version is valid, otherwise the upgrade process ends. Here, judging whether the upgrade file of the intermediate version is valid can be realized by reading the version number and other contents of the upgrade file. For example, an intermediate version is only considered valid if its base version matches the version the end device is currently running.

[0032] In the software upgrading method of the terminal device in this embodiment, since the process of judging whether the intermediate version is valid is also included before performin...

Abstract

The invention discloses a software updating method of terminal equipment. The terminal equipment comprises a first memory. The software updating method comprises the following steps of: step 1, updating original edition software of the terminal equipment to a middle edition by adopting an updating file of the middle edition in a mobile storage device through the terminal equipment; step 2, recording mark information in the middle edition software, the mark information representing to update the terminal equipment to the middle edition from the original software edition; step 3, the middle edition software executing a data backup operation on the first memory; step 4, updating the middle edition software to a target edition by an updating file of the target edition in the mobile storage device through the terminal equipment; and step 5, executing a data reduction operation on the first memory. According to the method disclosed by the invention, a data backup function is realized in the system of the terminal equipment, so that the software and plugs which are installed by a user, use recordings, registration information and the like are prevented from being lost in the process of updating and the method is good in use experience.

Description

technical field [0001] The present invention relates to a method for upgrading software, in particular to a method for upgrading software of terminal equipment. Background technique [0002] It is the general trend that digital TV replaces analog TV, and conversion from analog TV to digital TV has been carried out in many areas. Because the software system of the digital TV is relatively complicated, and the software system will be constantly updated. Therefore, the software system upgrade of digital TV has become a problem that needs to be solved. [0003] In the existing method for upgrading digital TV software, there is one method that stores the upgrade image file in a predetermined directory of a removable storage device such as a USB flash drive. After the upgrade process is started in the terminal device, the above-mentioned image file is written into the internal memory of the digital TV in an overwritten manner. The overall process of this upgrade method is simpl...
