Problems solved by technology

Loader plays a vital role in the normal work of the set-top box and subsequent software upgrades. Once there is a problem with this program, it will directly affect the user's use
Ordinary one-stage single-Loader software is generally only used to upgrade data other than the Loader, and it is not easy to upgrade itself. Once the Loader itself fails

Embodiment Construction

[0018] see image 3 Shown, the set-top box upgrade software of the present invention is the software structure of a two-stage type double Loader, two-stage type refers to the Starter module and the Loader module, and these two modules are independent respectively, store respectively; Double Loader refers to the main Loader and the backup Loader. The Starter part includes system initialization, dual Loader verification, main process verification, and detection of upgrade requirements; the Loader part is mainly to guide the upgrade process. The Starter part and the Loader part are partitioned and stored in Flash.

[0019] Such as Figure 4 Shown, based on above-mentioned software basis, the double Loader upgrading method of set-top box of the present invention comprises the steps:

[0020] Step 100: After the power is turned on, the CPU first runs the Starter program, and detects whether there is an upgrade request in the Starter;

[0021] Step 200: If the Starter detects tha...

Abstract

The invention provides a double-Loader updating method for set-top box, which includes the following steps: turning on the power, running the Starter program firstly by CPU, detecting whether the upgrade is required; if required, skipping to the main Loader for updating; if the main Loader is broken, skipping to the backup Loader for updating; if updating request is not detected or two Loaders are broken, skipping to the application program; restarting set-top box after the Loader program is updated smoothly, comparing the double Loader by the Starter program, replacing the original non-updating Loader with the new updated Loader, and then skipping to the application program. The updating method not only can realize update of program or data outside Loader, but also can realize self-updating of Loader, thereby greatly reducing failure rate of set-top box.

Description

【Technical field】 [0001] The invention relates to an upgrading method of a set-top box, in particular to a double-safety double-Loader upgrading method of the set-top box. 【Background technique】 [0002] In recent years, with the promotion of cable digital TV, cable digital TV set-top boxes have gradually entered thousands of households. During the use of set-top boxes, with the continuous introduction of cable digital TV value-added services, radio and television operators have requirements for upgrades; at the same time, set-top box suppliers may also request software upgrades to solve discovered software defects. Therefore, the demand for software upgrades of set-top boxes continues to rise. [0003] Such as figure 1 As shown, the common set-top box upgrade software (Loader) is a one-stage single Loader structure, and its upgrade method is usually as follows figure 2 As shown, step 10: when the power is turned on, the CPU first runs the Loader program. If the Loader i...
