Abstract
A multimedia I/O interface device for cars is provided, including a player data bus, a player I/O interface, a microprocessor, a memory unit, a USB OTG controller, a buffer, and an MHE. The player data bus and player I/O interface are connected to a multimedia player for airplane seats. The multimedia player for airplane seats is an audiovisual player. The microprocessor controls the data input/output and the storage of the multimedia player. The USB OTG controller, the buffer, and the MHE form a USB connection and transmission interface. The multimedia I/O interface device of the present invention is a connected to a USB connector and a card reader interface through the USB OTG controller and the MHE, respectively. Therefore, the multimedia device can be connected to a multimedia storage device with a USB interface or a flash memory for bi-direction data transmission.
