Abstract

The invention provides a method for ensuring the success in upgrading a set-top box, comprising the following steps: defining an upgrading status flag, an upgrading mode flag, an upgrading parameter check flag and upgrading parameters of the set-top box, and storing the flags and parameters in an EEPROM (electrically erasable programmable read-only memory) of the set-top box; when a main program of the set-top box detects an upgrading request transmitted by a front-end network of a broadcast television operator, recording the upgrading parameters transmitted by the corresponding front-end network into the EEPROM, and judging whether the set-top box needs to be upgraded according to the flags; starting the upgrading program and receiving upgrading data when upgrading is needed, and modifying the upgrading status flag; and operating the main program of the set-top box if upgrading is not needed. The invention can ensure normal operation of upgrading of the set-top box, and when special events such as power cut and the like are encountered, upgrading can be restored and continued automatically.

Description

【Technical field】 [0001] The invention relates to an embedded technology, in particular to a method for ensuring the success of an upgrade of a set-top box, which belongs to the field of set-top boxes. 【Background technique】 [0002] With the large-scale popularization of digital TV in the country, the function of the digital TV set-top box as a digital TV terminal product is becoming more and more powerful. Broadcast TV operators are required to upgrade, and at the same time, as a supplier of set-top boxes, they can introduce new software. As the functions of digital TV set-top boxes become more and more abundant, the original set-top boxes must be upgraded through OTA (based on the short message mechanism), and ensuring the success of the upgrade is the most important requirement of the upgrade program. The upgrade of the traditional digital TV set-top box is to receive the data sent by the front-end network of the broadcast TV operator, then erase the data on the flash b...
