Set-top box fault repair method and system

Abstract

The invention discloses a set-top box fault repair method. The method comprises the following steps: detecting whether a successful boot signal is received, and if not, then activating a self-inspection mode to check a boot program code; reading a preset check code, based on the check code, checking the boot program code step by step, and outputting a corresponding error code according to a check result; encrypting the error code based on a DES and transmitting the error code to a repair server; and parsing the encrypted error code by the repair server and outputting a corresponding repair data stream, and receiving the repair data stream by a set-top box and repairing the boot program code based on the repair data stream. The set-top box fault repair method provided by the invention checks the code of the set-top box which has not been successfully started, outputs the corresponding error code, encrypts the error code and outputs the error code to the repair server, and then the repair server parses the error code and outputs the repair data stream to perform burning repair on abnormal data blocks; and besides, software repair can be realized quickly, the time required to repair can be reduced and customer experience can be improved.

Description

technical field [0001] The invention relates to a set-top box failure repair method and system, belonging to the field of digital television. Background technique [0002] With the rapid development of digital technology and the widespread use of digital TV set-top boxes, most set-top boxes now use a high-security encryption system to protect content from being cracked and greatly improve security. However, with the widespread application of high-security systems, there are also some hidden dangers in the use of set-top boxes. For example, the programs of high-security set-top boxes are damaged or run abnormally, and they cannot be turned on normally. Due to the high-security feature, it is not possible to reprogram new software through the serial port of the machine, and restore it through the USB interface or OTA. Therefore, once the machine cannot be turned on, it means that the machine will be scrapped, which is a waste of resources for radio and television operators or...
