Embodiment Construction

[0027] Please refer to FIG. 2 , which shows the division method of the system software memory in the TV set of the present invention. It includes four parts: data area 31 , application program area 33 , update program area 35 and boot program area 37 . Corresponding to different manufacturers or different platforms, the order of these four parts can be changed.

[0028] After booting, the first program to be executed is the bootloader. Usually, to achieve the purpose of software update, two flags are set in the system software: a flag for updating an update program (named as flag A) and a flag for updating an application program (named as flag B). In the application program, by downloading a linkage descriptor (Linkage Descriptor) from the network, it can be obtained whether the new software on the current network is an update program or an application program. If it is an update program, set flag A to "TRUE"; if it is an application program, set flag B to "TRUE". The boot ...

Abstract

A method for updating software of TV system with power-off protection includes dividing storage of TV to be four regions of data region, application program region stored with application program for realizing application function of TV, update program region stored with update program for realizing download of update application program and update program, and guide program region; restoring update program region by said application program when update program is damaged and storing update code in update program region to finalize restoration of update program region with said code when restoration is started.

Description

【Technical field】 [0001] The invention relates to a TV system software update method with power-off protection, in particular to a TV system software update method with power-off protection that can reduce storage space requirements. 【Background technique】 [0002] With the advent of the era of home appliance integration, current TV products, such as 3C TV, not only have traditional viewing functions, but also have various functions such as browsing websites and video-on-demand. Such a TV product has a memory storing various application programs inside it, or in a device such as a set-top box connected to it, usually a flash memory (Flash Memory). When the user inputs a certain operation signal, the central processing unit calls out the corresponding program from the memory, and executes the operation set by the program. In order to improve the performance of the TV or expand its functions, TV manufacturers will launch new system software from time to time, and users need t...
