Problems solved by technology

Flat-panel software storage is generally stored in SMD Flash (Nand Flash). For the convenience of maintenance, it often provides a convenient way to upgrade software. Increasingly complex, often with its own operating system
If you use the traditional serial port to upgrade, the time will be longer, which is not conducive to production and maintenance
In addition, it needs to be explained that generally speaking, Nand Flash is prone to bad data blocks. If you use the batch program writing method, the program may not run normally due to Flash bad blocks.

Embodiment Construction

[0033] The following uses the digital liquid crystal all-in-one TV LHD4033US as an example to illustrate the present invention:

[0034] A digital liquid crystal television uses a USB interface to upgrade the Flash interface, that is, a PCI expansion interface is reserved on the above-mentioned television platform. Its microcomputer system includes a microprocessor, a clock generator, a data buffer, an interrupt controller, a bus controller, a keyboard adapter, a frame management unit and a PCI bus input / output unit. The USB interface connected to the microcomputer system is provided with two USB sockets, a USB port master controller and a USB serial interface engine. The PCI bus is connected with the PCI expansion interface reserved for the main control system platform of the TV set, and is provided with a main PCI interface, a secondary PCI interface and a PCI controller.

[0035] to combine figure 1 , a more specific example is: the PCI expansion interface is provided wit...

Abstract

The invention discloses an upgrade method of a USB interface used for a digital liquid-crystal-display television and an interface thereof. The technical characteristics of the invention are that: a USB input interface which is connected with a TV board is designed; a software control program capable of reading the USB interface is added into Pmon (which is a program for TV boot); an operating system software stored on a USB disc, boot LOGO pictures, a PMON program, partial application software comprising APP, MiddleWare and Driver program, factory partial initialization data packet are copied into Nand flash again so as to realize the upgrade of a TV software system. The upgrade method and the interface disclosed by the invention can solve the failure caused by damage and loss of the data of the system software during production and repairing and have the advantages of being simple and quick.

Description

technical field [0001] This group of inventions relates to a method and an interface for upgrading the software system of a digital liquid crystal television, in particular to a method for upgrading a digital liquid crystal television using a USB interface and the interface thereof. Background technique [0002] It is one of the trends that flat-panel LCD TVs are developing towards digital. After adopting digital TV, in the analog channel that can only transmit one ordinary analog TV program, 5 to 6 programs of DVD quality can be transmitted, and the channel utilization rate is greatly improved. At the same time, the reliability of TV program transmission and the quality of TV programs are greatly improved. [0003] At present, after digital processing is used in flat-panel LCD TVs, the software control framework and software volume have undergone very obvious changes compared with analog TVs. Flat-panel software storage is generally stored in SMD Flash (Nand Flash). For t...
