The present invention discloses a video player, comprising a decoding and control unit for outputting decoded video and audio signals; a storing unit for storing an application software capable of working without starting a computer operation system; a video processing unit for processing decoded video signals outputted by the decoding and control unit; an audio processing unit for processing decoded audio signals outputted by the decoding and control unit; an Optical disc driver's multi-use control circuit for multi-use controlling a DVD Optical disc driver of the computer; and a switch unit for switching the video processing unit and the audio processing unit to be coupled to the display and the sound box after monitoring a shut-off signal of the computer, and in the meantime switching two outputs of DC power to the video player. In the present invention, by using a unique switch unit to process switching by monitoring the shut-off signal, hardware sources of a PC can be abundantly in use to make video of multimedia products play without turning on the PC, therefore avoids adding new operation program.
