In-vehicle media shared system based on DLNA

Abstract

The invention relates to an in-vehicle media shared system based on DLNA. The in-vehicle media shared system based on the DLNA includes an in-vehicle navigation entertainment device, a personal consumer electronic device, and a router, which are accessed to a network through a DLNA protocol stack; the in-vehicle navigation entertainment device and other in-vehicle navigation entertainment devices are connected in a point-to-point manner or by the router; and the in-vehicle navigation entertainment device and the personal consumer electronic device are connected in a point-to-point manner or by the router. Compared with the prior art, the in-vehicle media shared system of the invention system is good in compatibility, good in flexibility and easy in use, can achieve seamless interconnection between devices, and can substitute a conventional technical scheme to realize the in-vehicle sharing.

Description

technical field [0001] The invention relates to a data sharing system, in particular to a DLNA-based in-vehicle media sharing system. Background technique [0002] Today, consumer electronic devices are becoming more and more pervasive in our daily lives. In these devices, a large number of digital media files, such as pictures, audio and video, etc. are stored. When the driver and passengers enter the car, how to realize the sharing of media files between the personal consumer electronic devices and the navigation and entertainment devices in the car, as well as between these electronic devices in the car? At present, there are several technical solutions as follows. [0003] Copy between different systems through mass storage devices, such as CD / DVD discs, U disks and SD cards, etc. This solution requires each system to support the adopted large-capacity storage device, resulting in additional hardware costs. Moreover, media files need to be copied many times, so they ...

Problems solved by technology

In each piconet, only one master device can communicate with slave devices at the same time, and slave devices cannot communicate directly

This kind of network topology cannot realize complex device interconnection applications. For example, in a car equipped with independent front and rear seat entertainment systems, once the user's Bluetooth mobile phone is connected to the front seat entertainment system for music sharing, it cannot be connected to the rear seat entertainment system at the same time. interconnect
