Problems solved by technology

This prior art achieves gradual mute only by controlling the volume, but in daily operation, in addition to turning on and off the mute, there are other transitions of sound effects, such as the switching process of the sound mode, etc. Still can't solve the above technical problems

Embodiment Construction

[0020] The preferred embodiments of the present invention will be further described below in conjunction with the accompanying drawings and specific implementation methods.

[0021] The system of receiver audio frequency jump buffer of the present invention, as shown in Figure 1, comprises sound effect processing module, and its effect is to select audio frequency input, adjust volume and treble bass etc.; One central processing unit CPU controls sound effect by IIC bus module, and the audio processing module controls the audio power amplifier module through an I / O port to achieve the mute on and off function.

[0022] The method for receiver audio jump buffering described in the present invention comprises the following steps:

[0023] A. Compare the new sound effect parameters to be set with the current sound effect parameters;

[0024] B. If the change of the new parameter of the sound effect exceeds the acceptable range, perform sound transition buffering, that is, gradua...

Abstract

The invention discloses an approach and system of receiver sound frequency skip buffering, it includes next steps: CPU controls a sound effect processing module through IIC bus to compare the new sound effect parameter to be set with the existing sound effect parameter; if the parameter change exceeds the preset range, the sound jump buffering process is conducted that it makes the current sound effect value change gradually to the new parameter value, if not, it needs no buffering process, only directly writes the new parameter into relative register of said sound effect processing module.

Description

technical field [0001] The invention relates to a receiver sound processing circuit and method, in particular to a TV audio jump buffering method. Background technique [0002] In the prior art, when watching TV, the sound jumps are often encountered. For example, when the power is turned on, the volume is restored from mute to the set volume. When switching between sound modes, changing channels or switching channels, the system will first mute and then restore. volume etc. [0003] Existing color TV sets often use the method of directly switching from the previous sound effect to the new sound effect when the above-mentioned sound jumps. , Surround, Stereo, Subwoofer, Balance, etc., by adjusting the parameters of these sound effects, different sound modes can be obtained. [0004] This processing method in the prior art makes the listener’s sound change greatly, which will cause a kind of harm to the ears and the mind, and the front and rear shapes of the speaker change ...
