Specifically, it can be the MAC (Media Access Control, Media Access Control) address of the device, and the IMEI (International Mobile Equipment Identity, International Mobile Equipment Identity) of the mobile device. Identity code), IMSI (International Mobile Subscriber Identification Number, International Mobile Subscriber Identification Code), Phone Number (mobile phone number), etc. A device whitelist is stored in the local vehicle-mounted device, specifically, the device identifiers of the smart devices may be stored in a list form. When the device identifier of the second smart device matches the device identifier in the device whitelist, it indicates that the second smart device is a connectable device.

Alternatively, it is judged whether the device identifier of the second smart device matches the device identifier of the connectable device stored in the device blacklist; if the two do not match, it is determined that the second smart device is a connectable device. Specifically, a device whitelist or a device blacklist may be selected according to actual conditions.

Step 103: Receive the control instruction sent by the second smart device through the DLNA protocol, and perform corresponding operations according to the control instruction; the control instruction includes audio and video data upload instruction, play instruction, pause instruction, stop instruction, search instruction, fast forward instruction or Fast rewind command, and corresponding audio and video data is encapsulated in the audio and video data upload command.

In the embodiment of the present invention, the audio and video data upload instruction is an instruction sent by the second smart device to the vehicle-mounted device, and is used to send audio and video data to the vehicle-mounted device; at the same time, the vehicle-mounted device can also send audio and video data to the second smart device through the DLNA protocol. The video data download command downloads the audio and video data encapsulated in the audio and video data download command to the second smart device, so that data sharing between the vehicle-mounted device and the smart device is realized through the DLNA protocol.

The embodiment of the present invention provides a method for sharing audio and video data among multiple vehicle-mounted devices. When the Bluetooth of the vehicle-mounted device is in use, it connects with other smart devices through the DLNA protocol, so as to realize data sharing. The method does not require additional storage devices such as data cables or U disks, is simple, and can quickly realize data sharing between multiple devices on the vehicle.
