Method for recovering serial number of set-top box and set-top box

Abstract

The invention relates to the field of set-top boxes and discloses a method for recovering the serial number of a set-top box and the set-top box. As for the method for recovering the serial number of the set-top box and the set-top box, a region for saving the serial number of the set-top box is distributed from an electrically erasable read-only memory of the set-top box, and the serial number of the set-top box is backed up in a backup memory; when the set-top box is switched on, the set-top box can automatically detect whether the serial number of the set-top box in the electrically erasable read-only memory used for storing the serial number of the set-top box is damaged or not; and when the set-top box detects that the serial number of the set-top box in the electrically erasable read-only memory used for storing the serial number of the set-top box is damaged, the backup serial number of the set-top box can be automatically programmed into the electrically erasable read-only memory. The invention provides the method for recovering the serial number of the set-top box, which is convenient and fast, and can recover the serial number of the set-top box without using a special recovery tool, provide convenience for a user and reduce the after-sales maintenance cost.

Description

technical field [0001] The invention relates to the field of set-top boxes, in particular to a method for recovering the serial number of the set-top box and the set-top box. Background technique [0002] Set-top boxes are widely used in home multimedia. If the set-top box is damaged, it needs to be repaired at a special after-sales maintenance point. [0003] At the after-sales repair point of TV set-top boxes, maintenance personnel need to perform software upgrades or hardware repairs on site, especially hardware repairs often cause the unique identifier (serial number of the set-top box) originally programmed in the flash memory to be cleared during the repair process. Lose. The on-site after-sales maintenance point does not have a special tool for programming the serial number, but the serial number of the set-top box is the only identification to distinguish between the set-top boxes. Therefore, if the serial number of the set-top box is cleared during the maintenance...
