Embodiment 1

[0024] This embodiment provides a method for upgrading firmware of a TV terminal, which is applied to a smart TV terminal. The smart TV terminal, such as image 3 As mentioned above, it mainly includes: system-level chip, embedded eMMC memory, double-rate synchronous dynamic random DDR memory, communication module, function module, interface module, frame rate control chip, FLASH chip, central control board, backlight driver board.

[0025] The firmware upgrade of this method is carried out when the TV is turned on, such as figure 1 mentioned, including:

[0026] Step 101, by communicating with a server, when a new version of the firmware file is detected, downloading the new version of the firmware file from the server and saving it to a preset storage area;

[0027] Firmware is a program that can be upgraded by the user through a specific refresh program. It refers to the device driver program stored inside the device. It is generally stored in the EEPROM or FLASH chip in t...

Embodiment 2

[0071] This embodiment is a device for firmware upgrade of a TV terminal. The problem-solving principle of the device is similar to the method described above. Therefore, the implementation of the device can refer to the implementation of the method, and the repetition will not be repeated.

[0072] This embodiment also provides a device for upgrading firmware of a TV terminal, including a memory and a processor, and the processor is used for:

[0073] By communicating with the server, when a new version of the firmware file is detected, the new version of the firmware file is downloaded from the server and stored in a preset storage area;

[0074] When starting the module firmware upgrade, read the new version firmware file from the preset storage area;

[0075] Use the read firmware file of the new version to upgrade the module firmware.

[0076] The above-mentioned processors are specifically used for:

[0077] When starting the module firmware upgrade, the new version of...

Embodiment 3

[0090] This embodiment provides a device for firmware upgrade of a TV terminal, such as Figure 4 As shown, the above-mentioned devices include:

[0091] The firmware file obtaining unit 401 is configured to download the new version of the firmware file from the server and save it to a preset storage area when a new version of the firmware file is detected by communicating with the server;

[0092] A firmware upgrade starting unit 402, configured to read the new version of the firmware file from the preset storage area when starting the module firmware upgrade;

[0093] A firmware upgrade unit 403, configured to use the read firmware file of the new version to upgrade the module firmware.

[0094] The preset storage area is a flash memory area of ​​the mainboard for saving system upgrade files.

[0095] The firmware upgrade startup unit 402 is specifically used for:

[0096] When starting the module firmware upgrade, the new version of the firmware file in the flash memory ...

Abstract

The invention discloses a method and a device for upgrading firmware of a TV terminal, which solves the problem that the firmware file of a new version can only be written into a firmware module through an external memory for upgrading. The method includes: when a new version firmware file is detected by communicating with a server, downloading the new version firmware file from the server and saving it to a preset storage area; when starting a module firmware upgrade, reading from the preset storage area Get the new version firmware file; use the read new version firmware file to upgrade the module firmware. The invention adopts the dumping method of the random access memory, and can complete the firmware update in the background during the normal use of the TV, without affecting the normal viewing of the TV by the user.

Description

technical field [0001] The invention relates to the field of firmware upgrading, in particular to a method and device for firmware upgrading of a television terminal. Background technique [0002] With the enhancement of smart TV functions, there are more and more various modules such as frame rate control chip, screen driver board, backlight driver, etc. on the smart TV main board, and the update and upgrade of module firmware is also a very important requirement. The common module firmware upgrade method in the industry is generally to put the firmware upgrade package in a USB flash drive, and detect whether there are various firmware upgrade packages in the USB flash drive during the start-up stage of the smart TV. During the upgrade process, the user cannot use the TV. If there is a need to update the module firmware, it can only be updated by after-sales personnel, which has high labor costs and poor real-time performance. [0003] The over-the-air download technology ...
