Suppose that the volume amplification coefficient that the user is provided with television receiver is: 10; This coefficient usually shows as the volume adjusting rank (be shown as the lattice number of volume, the lattice number is many more, and the expression volume is big more) that television receiver shows;
The program source volume of supposing channel A is 1; The program source volume of channel B is 1.5; The program source volume of channel C is 0.5;
Like this, the user at A, B, when switching between three channels of C, the final volume of acquisition will be respectively:
Channel A volume=program source volume 1 * television receiver volume amplification coefficient 10=10
Channel B volume=program source volume 1.5 * television receiver volume amplification coefficient 10=15
Channel C volume=program source volume 0.5 * television receiver volume amplification coefficient 10=5
Like this, the user will hear the sound of different volumes; If user's satisfied 10 these volumes when viewing channel B, channel C, just have to by hand volume is adjusted to satisfied volume 10, like this with cumbersome so.
