Problems solved by technology

[0003] However, the sound formats of different signal sources are different. At this stage, most of the sound sensitivity is adjusted by manually adjusting the parameters of the gain value and offset value. The gain value refers to the input signal gain value, and the offset value refers to the offset value. The manual adjustment method has a large workload,

Embodiment Construction

[0031] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the accompanying drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0032] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of ill...

Abstract

The invention relates to the technical field of television signal source adjustment, and discloses a signal source channel sound sensitivity adjustment method and system based on power protection feedback, and the method comprises the steps: an audio source sound reference, i.e., the preset reference sound source data is established, thereby enabling the audio information of various audio formatsof a signal source of each channel to be consistent; and then the master control module compares the audio data of each signal source with the power over-protection data by using the over-protection mechanism of the power amplifier, namely the power over-protection data of the application, so as to obtain the real-time gain value of the signal source, so that the sound output power of each signalsource can be consistent. Therefore, the phenomenon that the sound of the television changes suddenly when the television converts the signal source is avoided, meanwhile, manual debugging can be replaced, and the whole process is more automatic.

Description

technical field [0001] The invention relates to the technical field of television signal source adjustment, in particular to a method and system for adjusting sound sensitivity of a signal source channel based on power protection feedback. Background technique [0002] At present, a TV refers to a device that uses electronic technology to transmit moving images and audio signals according to the persistence of vision and visual psychology of the human eye. [0003] However, the sound formats of different signal sources are different. At this stage, most of the sound sensitivity is adjusted by manually adjusting the parameters of the gain value and offset value. The gain value refers to the input signal gain value, and the offset value refers to the offset value. The manual adjustment method has a large workload, and the adjustment range of the sound sensitivity is manually judged, so the sound sensitivity adjusted by different people is not the same, and there is a large err...
