Abstract

The invention discloses a television receiver and a volume adjusting method thereof. The volume adjusting method of the television receiver comprises the steps that a volume input value is received, the volume input value is a volume logic value input by a user; a volume curve preset by the user is determined from the volume curves corresponding to the volume adjusting mode preset by the television receiver and defined by a user; a fitting method of the volume curves corresponding to the volume adjusting mode comprises a Bezier curve fitting method; a volume curve indicates a corresponding relation between a volume input value and a volume output value, the volume output value is a logic value controlled by volume decibel and output by the television receiver; the volume output value corresponding to the volume input value is output and received according to the volume curve preset by the user. The television receiver and the volume adjusting method of the television receiver can perform individual volume adjustment according to the volume curve preset by the user so as to fully meet different requirements of different users for volume adjustment.

Description

technical field [0001] The invention relates to the technical field of television, in particular to a television receiver and a volume adjustment method thereof. Background technique [0002] A TV receiver is a terminal device that receives TV broadcast signals, and displays and broadcasts after receiving and decoding cable TV signals or wireless TV signals, referred to as TV for short. At present, the volume adjustment method used by TV receivers is to set a factory standard volume curve before leaving the factory. The volume curve indicates the corresponding relationship between the volume input value and the volume output value during the TV volume adjustment process. It is generally a non-linear curve. , where the volume input value is a volume logical value manually input by the user when the TV volume is output, and the volume output value is the logical value of the volume decibel control actually output by the TV receiver when the TV volume is output. At present, th...
