A multimedia jack cable capable of being converted into three or four polarization is provided to reduce expense for buying a jack cable by performing two functions with one jack cable. A multimedia jack cable includes a casing(15), a terminal pin(20), a audio signal part(40), a video signal part, and a control lever(80). The terminal pin includes a plurality of coaxially arranged four pole electrodes(28). The audio signal part includes three pole connection pins(42), which are mounted and rotated at the inner side of the casing. The three pole connection pins is connected to an audio jack cable through a cable. The video signal part includes four pole connection pins rotated at the inner side of the casing. The control lever electrically connects three or four pole connection pins to the four-pole electrode of the terminal pin.
