Embodiment

[0049] A method for designing sound effect parameters of a flat-panel TV, specifically comprising the following steps:

[0050] S1. The sound parameters are separated from the system software into two corresponding files, specifically:

[0051]S1.1 write all the parameters bound to the signal channel, such as Prescale, mode setting, volumenonlinear and other parameters, into multiple arrays according to the different signal channels, and these arrays are stored in a basic sound effect parameter file. In this embodiment, use The file format in the basic sound effect parameter file uses the ini file as an example.

[0052] An example of the separated basic sound effect parameter file is as follows: wherein, its basic sound effect parameter part includes (taking Prescale and mode setting parameters as examples in this embodiment):

[0053] [Source_Prescale]

[0054] MainSpeaker_Prescale_ATV=0x21

[0055] MainSpeaker_Prescale_DTV=0x9

[0056] MainSpeaker_Prescale_AV=0x19

Abstract

The invention discloses a method for designing sound effect parameters of a flat-panel TV, which includes separating the sound parameters from system software into two corresponding files, performing framework docking on the two files of sound parameters and the core system software, and including the process of starting the system software During docking and parameter debugging, the design process docking and production maintenance are processed by using independent sound parameter files. The method of the present invention is used to solve the problem of low efficiency and reliability in each link of sound parameter design, production, and after-sales, and can realize the design efficiency of sound effect parameters and achieve the goal of independent design and control of sound effect parameters.

Description

technical field [0001] The invention relates to the technical field of audio processing, in particular to a method for designing sound effect parameters of a flat-panel TV. Background technique [0002] In the development and design of the TV sound system, the general design method is to adjust the sound parameters of the prototype to make each sound effect mode achieve the predetermined sound effect after the appearance and structural parts of each model are determined. During the debugging process, the method used is to open the sound parameter file through the editing tool on the computer side, complete the editing on the computer side, adjust the final state of the parameter file and put it into the core software system to compile into the firmware. [0003] Traditional TV sound software design technology has always had the following problems: [0004] a. The sound quality parameters of the TV are all stored in one file, and a set of system software cannot be compatible...
