Embodiment Construction

[0037] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0038] see figure 1 , is a flow chart of the method for automatic upgrading of IPTV in the preferred embodiment of the present invention. Such as figure 1 As shown, the method for automatic upgrading of Internet TV provided by the present invention comprises the following steps:

[0039] First, after the start, in step S1, dual-machine hot backup is adopted. Configure two Nand-flashes with exactly the same capacity. Then set a flash memory equipped in the bootloader as the boot partition to store the currently used main program, and set another flash memory as the backup partition to store the backup of the currently used main program.

[0040] Then in step S2, the upgrade program checks the version number of the current main program to judge w...

Abstract

The invention relates to a method for automatically upgrading a network television, which comprises the following steps of: S1, setting one flash memory for a boot subarea to store a current used main program and setting the other flash memory for a backup subarea to store the backup of the current used main program in a bootloader; S2, checking the version number of the current main program by an upgrade program, judging whether upgrade is needed, if so, turning to a step S3, otherwise, ending; S3, checking the equipment number of the current backup subarea and the bad block of the flash memories; S4, flashing the backup subarea to load upgrade data; S5, checking whether the backup subarea is flashed successfully, if so, turning to a step S6, otherwise, turning to the step S3; and modifying the bootloader to change the original backup subarea into the boot subarea. The method for automatically upgrading the network television ensures that the network television cannot be upgraded safely by adopting a double-machine hot backup mode, and reduces the cost of home maintenance.

Description

technical field [0001] The present invention relates to network television, more specifically, relates to a method for automatically upgrading network television. Background technique [0002] Nand-flash memory is a kind of flash memory. It adopts nonlinear macrocell mode inside, which provides a cheap and effective solution for the realization of solid-state large-capacity memory. Nand-flash memory has large capacity, fast rewriting speed, and is suitable for storing large amounts of data, so it has been more and more widely used in the industry, such as embedded products including digital cameras, MP3 walkman memory cards, small and exquisite U disk, etc. NAND-type flash memory is erased in units of blocks. The write operation of the flash memory must be performed in a blank area. If the target area already has data, it must be erased first and then written. Therefore, the erase operation is the basic operation of the flash memory. [0003] The Nand-flash protocol allow...
