Description
Technical field
The present invention relates to TV technology, particularly relate to radiotelevisor and volume curve adjustment method thereof.
Background technology
Radiotelevisor is the terminal unit of received tv broadcast signal, cable TV signal or wireless television signal is connect
Carry out showing and broadcasting after receiving decoding, be called for short TV.The volume adjusting mode that radiotelevisor uses at present is before dispatching from the factory
Be fixedly installed the volume curve of a manufacturer's standard, this volume curve instruction television sound volume regulate during volume input value with
Corresponding relation between volume output valve, the most nonlinear curve, volume input value therein is to export at television sound volume
When the volume logical value that is manually entered by user, volume output valve is that radiotelevisor is real television sound volume exports when
The logical value that the volume decibel of border output controls.This volume curve is factory's volume input value according to standard setting voluntarily at present
And the corresponding relation between volume output valve.Such as: when user by volume adjusting to a certain volume input value when, export certain
The volume of one volume output valve；When user by volume adjusting to another volume input value when, export another volume output valve
Volume.Before actual TV receiver dispatches from the factory, factory needs the volume curve of radiotelevisor is adjusted and is set
To meet requirement of dispatching from the factory.
It practice, the volume curve fit approach that radiotelevisor manufacturer takes at present is generally fitting a straight line mode,
