A method for preventing television software upgrading errors

Abstract

The invention provides a method for preventing upgrading errors of television software, and belongs to the field of system software version marking and identification judgment. Key points of the technical scheme are as follows: the device comprises a base; the television scans the USB flash disk or the network; searching whether to-be-upgraded software exists or not; if yes, directly reading the name and version number information of the to-be-upgraded software; comparing the information with comparison information pre-stored in a local system; if the comparison is successful, determining thatthe comparison is successful, if yes, the television reads the software labeling file from the software program code; judging whether the software name and version number information in the softwarelabeling file is correct or not; if the software program code is correct, the television reads and judges whether model information of the television exists in a matched complete machine model list inthe software program code or not; and if yes, the television reads and judges whether the software verification code in the software program code is consistent with the verification code reserved bythe television, if yes, a software upgrading process is started, and if only one link of the searching, comparing and judging processes has errors, the upgrading process is not started.

Description

technical field [0001] The invention relates to the field of system software version labeling and identification and judgment, in particular to the field of how to prevent errors in TV software upgrades. Background technique [0002] At present, with the rapid development of electronic technology and the constant change of consumer demand, the upgrading cycle of electronic products is shortening day by day. The upgrading and replacement of electronic products includes both the replacement of the whole product and the upgrading of TV software for existing products, so as to realize the improvement of product performance or the enhancement of functions. Among them, electronic products such as televisions and mobile phones are usually released in the form of series products. The same product series includes multiple terminal product models. The specific status differences between different models of terminal products in the same series include screen type and size, system perfo...

Problems solved by technology

At present, the software status is usually distinguished by identifying the software name and version number. After the software name and version number are compared, the terminal system will consider the upgrade file to match the local machine. It is impossible to distinguish the artificial modification of the software name and version number, which may easily cause The whole terminal mistakenly upgraded the system software whose name and version number match, but the software program does not match, resulting in the upgrade failure or abnormal operation of the system after the upgrade
