The invention relates to a portable vehicle-mounted audio and video system. The system comprises a media data receiving unit and an audio and video data conversion unit; the audio and video data conversion unit is provided with a first universal serial bus (USB) interface; the media data receiving unit is connected with the audio and video data conversion unit through a high-definition multimedia interface (HDMI); the audio and video data conversion unit is used for collecting audio and video data output by the media data receiving unit through the HDMI interface, converting the audio and video data into data supporting UVC and/or UAC protocols, and projecting the data supporting the UVC and/or UAC protocols to a display unit of the vehicle-mounted information entertainment system through the first USB interface. The invention provides a low-cost multimedia audio and video function upgrading scheme of the in-vehicle entertainment system, and the problems that an existing in-vehicle entertainment system is difficult to upgrade and high in cost are effectively solved.
