Embodiment

[0023] In this example, by upgrading the software application program, the USB2.0 data interface, DDR buffer interface and serial FLASH interface are operated in time-sharing to realize the upgrade of the main program software of the TV. The system flow chart is shown in Figure 1.

[0024] Firstly, after booting, the TV main chip loads the main program from the serial FLASH to perform system reset and initialization settings, and then proceeds to the normal working state. In the normal working state, traditional software accesses the serial FLASH irregularly according to the needs of the working state. At this time, a mobile storage device is connected to the USB2.0 port and the program file to be upgraded is stored in the mobile storage device, and then the user sends an instruction to start the upgrade program, and the user will be asked for the upgrade password, and the upgrade program cannot be started without entering the correct password. Ask for the upgrade password repe...

Abstract

The invention relates to a television technique and provides a flat-TV software automatic updating method which is based on a USB interface and can automatically update the flat-TV software from the USB interface. The technical proposal of the invention is the flat-TV software automatic updating method based on the USB interface. The invention is characterized in that the method includes the following steps: the television is started and enters into a normal state and the USB 2.0 interface is connected; a software update application program is started according to the instruction of users; program files in a mobile storage to be updated are all transferred to a DDR buffer; the validity of the program files to be updated is checked to judge whether the validity is identical to the software-version ID of the present program files or not, if so, the program is withdrawn, and if not, the updating is carried out, the system carries out inspection automatically and after confirmation by inspection, the system is reset to work again. The invention is suitable for the flat-TV provided with a core major-chip supporting an independent USB 2.0 Host main-controller functional interface.

Description

technical field [0001] The invention relates to television technology, in particular to a method for upgrading software of a flat-panel television. Background technique [0002] With the rapid development of flat panel display technology, the flat panel TV market is rapidly expanding, and more and more functions are integrated. Due to the extensive use of digital signal processing technology in flat-panel TVs, complex structures, rich functions, and rapid technological changes, they are facing greater pressure in TV software upgrades in both production and after-sales service. In order to realize the online upgrade of the TV software in the traditional flat-panel TV, in the early stage, it can only be upgraded by opening the back cover of the TV and using a special tooling from a special socket. Later, a set of dedicated VGA cable and tooling can be used from the VGA port without opening the back cover of the TV. To upgrade, these two upgrade methods require a computer equi...
