In addition, the input unit 4 is configured to set an optical disc (Compact Disk, 5 KB05015 ^°), a VIDE® Compact Disc (VCD), and a Digital Versatile Disc (DVD). a storage device of at least one of the Blu-ray discs (Biu is a Disc' BD), and the update data and the media data MD can be stored in the storage device, and the storage unit is used to read the storage device. The updated information is centered with the multimedia material MD. In another embodiment, the input unit 4 can be a universal serial bus for connecting to the storage device (Universal Serial)

Bus, USB) FireWire (IEEE 1394), that is, the update data UD is stored in a portable platter or a storage hard disk having a corresponding serial bus or the FireWire, and by connecting the input unit 4. The update material UD is transferred to the inside of the audio-visual device. The digital signal processing unit 6 is connected to the input unit 4, and the digital k-processing unit 6 decodes the multimedia material md and the digital signal processing unit 4 generates a control signal CS. The control signal cs controls whether the control unit ίο enters an online update mode (〇n_line update mode) to perform a corresponding update action. The communication unit 8 is connected to the digital signal processing unit 6, wherein the communication unit 8 is a universal asynchronous transceiver interface (Universal)
