Firmware upgrading method and device for projection television

Abstract

The invention discloses a firmware upgrading method and device for a projection television. The projection television comprises a television control module and a projection control module. The firmware upgrading method comprises the following steps that: the television control module receives an upgrading descriptor in a television code stream; the upgrading descriptor at least comprises upgrading information of the projection control module; the television control module analyzes upgrading information from the upgrading descriptor, and downloads a firmware upgrading packet through the television code stream; the television control module sends the firmware upgrading packet to the projection control module; and the projection control module receives the firmware upgrading packet from the television control module, and performs upgrading operation according to the firmware upgrading packet. By means of the firmware upgrading method and device for the projection television disclosed by the invention, firmware can be upgraded conveniently in time; and, when being failed, a firmware or an operating system of a projection module can also be automatically repaired through the scheme.

Description

technical field [0001] The present invention relates to the technical field of projection televisions, and more particularly, to a method and device for upgrading firmware of projection televisions. Background technique [0002] Compared with traditional TV, miniature projection TV adopts the principle of projection, so that the TV screen is no longer limited by fixed size, and at the same time, it can realize the same signal input and picture and sound enjoyment as traditional TV. They have the advantages of protecting eyesight, large size, energy saving and environmental protection, as well as small size and light weight. The micro-projection TV system consists of two parts, the TV module and the projection module, which are controlled by two chips with different functions. As the micro-projection TV is a new product, its firmware is still in the process of continuous improvement. For example, for a projection module, the autofocus program is an important firmware related...

AI Technical Summary

Problems solved by technology

The current autofocus technology is not perfect, and the software algorithm of the program needs to be continuously modified and upgraded. If the micro projection TV purchased by the user cannot update the corresponding software algorithm in time, it will affect the user experience; similarly, for the TV module , it is also necessary to frequently upgrade the firmware version burned into the chip

[0003] Both the TV module and the projection module of the micro-projection TV need to be upgraded separately. Currently, the TV module is the same as the existing technology. It can be upgraded through the TS code stream, that is, the upgrade file in the code stream is obtained, and the TV module can be upgraded after passing the verification. Upgrade and update, and for the projection module, because its hardware has different parts such as CPU, ROM and FLASH from the TV module, it is impossible to upgrade the projection module while upgrading the TV module. If the module is upgraded, the projection module has to rely on communication with the server for self-upgrade or rely on the developer to upgrade the projection module after returning to the factory and disassembling the machine.

[0004] Therefore, in the prior art, it is more difficult and cumbersome to upgrade the projection module in the projection TV product. Whether it is the way of communicating with the server or the artificial upgrade after dismantling, the cost of the upgrade is increased and the user experience is reduced.
