Patent ID: 8000586

Claim:
A video player comprising: a decoding and control unit for receiving video and audio signals without starting an operation system of a computer and without powering a main board of the computer and then outputting decoded video and audio signals functioned by a control command; a storing unit for storing an application software capable of working without starting the operation system of the computer and without powering the main board of the computer; a video processing unit for processing decoded video signals outputted by the decoding and control unit and outputting the decoded video signals to a display after processing without starting the operation system of the computer and without powering the main board of the computer; and the video processing unit connecting the display by six circuit lines which represent signals R, G, B, H, V and ground signals respectively; an audio processing unit for processing decoded audio signals outputted by the decoding and control unit and outputting the decoded audio signals to a sound box after processing without starting the operation system of the computer and without powering the main board of the computer; and the audio processing unit connecting the sound box by 7 circuit lines which represent left and right sound channels from audio channel 1 to audio channel 3 and ground line respectively; an Optical disc driver's multi-use control circuit for multi-use control an 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.
