Abstract

The invention discloses an extended use method of an AV OUT interface. The signal output mode of the AV OUT interface is selected according to the occupancy of the three jacks of the AV OUT interface. The signal output modes include an AV OUT mode and a LINE OUT mode. Mode and LINE OUT mode are preset with corresponding codes. After selecting one of the modes as the signal output mode of the AV OUT interface, execute the corresponding code to control the video output jack, left channel jack and right channel jack to output the signal of the specified signal channel. The extended use method of the AV OUT interface of the present invention enables the AV OUT interface to output signals of various signal channels, so that the AV OUT interface realizes the function of the LINE OUT interface, solves the problem of single function of the existing AV OUT interface, and is very simple and practical.

Description

technical field [0001] The present invention relates to the field of mobile communications, in particular to a method, device, computer equipment and storage medium for expanding the use of an AV OUT interface. Background technique [0002] At present, the AV OUT interface, LINE OUT interface, and headphone interface are interfaces with independent functions. Among them, the AV OUT interface is used to output the picture and sound of the TV channel and CVBS channel, and the volume is fixed and uncontrollable; the LINE OUT interface is used to output the sound of all signal channels, and the volume is uncontrollable; the headphone interface is used to output the sound of all signal channels to Output in the form of low volume, and the volume is controllable. If a machine only has the AV OUT interface, it cannot realize the functions of the LINE OUT interface and the headphone interface, and the function is single and the applicability is poor.
