Problems solved by technology

[0002] In the existing TV, the user watches the TV with the same screen brightness and volume no matter in the noisy daytime or in the quiet late night. When the TV is turned on in the middle of the night, the TV is still turned on at the same brightness and volume during the day, which often affects the rest of the people around.
Also, wasting energy
At the same time, the user needs to make constant adjustments in the day and night mode, requiring the user to perform repeated operations, which is inconvenient to use

Embodiment

[0016] When leaving the factory, set the daytime critical time A as 7 o'clock, and the night critical time B as 22 o'clock. The CPU of the TV extracts the current time C from the Time and Date Table and Time offsetTable in the digital code stream through the tuner to 8:00, then turns on the daytime mode, and the brightness and volume of the screen remain in a normal state. If the extracted current time C is 20:00, the night mode is turned on, and the brightness and volume of the picture are set to 80% and 50% of the day mode, respectively.

[0017] When the critical time of day and night is defined by the user, a menu of setting critical time is added in the menu bar. Users can set the critical time of day and night according to their own situation.

Abstract

The utility model discloses a switching method between the daytime/night modes based on the digital television, aiming at providing a switching method between the daytime/night modes based on the digital television, which is able to switch between the daytime/night modes according to the start-up time to save electricity. The method comprises the following steps: setting up the critical time between the daytime the night, extracting the current time from the TDT table and the TOT table of the digital code flow, judging the daytime mode and the night model switching to the corresponding mode. When starting the television by means of the switching method, the starting mode is determined according to the current time information carried in the digital code flow and the picture brightness and the volume are automatically adjusted, so as to reach the purpose of saving electricity. Meanwhile, the utility model does not affect others and enhance the humanization of the television. The starting mode can be automatically adjusted, thus relieving the users from repetitive operations and providing great convenience for use .

Description

technical field [0001] The invention relates to a conversion method based on a day / night mode of a digital television. Background technique [0002] In the existing TV, the user watches the TV with the same screen brightness and volume no matter in the noisy daytime or in the quiet late night. When the TV is turned on late at night, it is still turned on at the same brightness and volume as during the day, which often affects the rest of people around. Moreover, electric energy is wasted. At the same time, the user needs to make constant adjustments in the day and night modes, requiring the user to perform repeated operations, which is inconvenient to use. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a day / night mode conversion method based on digital TV that can perform day / night mode conversion according to the power-on time, save electric energy, and is convenient to use.
