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
The present invention relates to a kind of data-sharing systems, especially relate to media sharing system in a kind of car based on DLNA.
Background technology
Now, consumer-elcetronics devices is more and more universal in our daily life.In these equipment, store a large amount of digital media files, for example: picture, Voice & Video etc.When driver and passenger enter into automobile, how to realize between the navigation amusement equipment in personal consumption electronic equipment and car, and media file between these car inner electronic equipments is shared? at present, there is following several technical scheme.
By mass-memory unit, for example: CD/DVD laser disc, USB flash disk and SD card etc. copy between different systems.This scheme needs each system to support adopted mass-memory unit, produces extra hardware cost.And media file need to through repeatedly copy, cannot plug and play.
Control the media play of consumer-elcetronics devices and the importing of Media Stream by special wire harness and agreement, for example: the iAP of Apple.This scheme is limited to the product of a certain company, cannot extensively support all electronic equipments.
By Bluetooth protocol, for example A2DP, VDP, AVRCP and FTP etc., realize at consumer-elcetronics devices and car inner electronic equipment, and Media Stream and file-sharing between car inner electronic equipment.This scheme is limited to Bluetooth technology itself, and Bluetooth technology adopts the master-slave network structure without base station.In each piconet, simultaneously only there to be a main equipment to communicate slave, between slave, can not carry out direct communication.This kind of network topology cannot realize complicated devices interconnect application, for example,, having equipped respectively in the automobile of independent front and back seat entertainment systems, once user's bluetooth cellular phone and front stall entertainment systems are interconnected, carry out music sharing, just cannot carry out interconnected with back seat entertainment systems simultaneously.
Summary of the invention
Object of the present invention is exactly to provide media sharing system in a kind of car based on DLNA in order to overcome the defect that above-mentioned prior art exists, this system compatibility is good, easy-to-use flexibly, between equipment, can realize seamless interconnectedly, can substitute conventional solution and realize media in car and share.
Object of the present invention can be achieved through the following technical solutions:
Media sharing system in a kind of car based on DLNA, comprise navigation amusement equipment, personal consumption electronic equipment and router in the car of multiple employing DLNA protocol stack access networks, in described car navigation amusement equipment with in other car, between navigation amusement equipment and in car, navigate between amusement equipment and personal consumption electronic equipment point to point connect or be connected by router.
Described point to point connect is the connected mode of Wi-Fi Direct or ad-hoc.
Described router is that Wi-Fi is or/and ethernet router.
Described DLNA protocol stack comprises uPnP agreement, HTTP/RTP agreement, ICP/IP protocol, Wi-Fi agreement and Ethernet protocol.
In described car, navigation amusement equipment comprise file system and media player, described file system is obtained and media streams from navigate in other car amusement equipment or personal consumption electronic equipment by network, and described media player is for the broadcasting of Media Stream.
Described personal consumption electronic equipment comprises household consumption electronic equipment and mobile consumer-elcetronics devices.
Compared with prior art, the present invention has the following advantages:
One, bring media in revolutionary car to share experience to user.
Two, seamless interconnected, can expand and tailorable device network topological structure, each device node all can be supported to connect and use.
Three, easy-to-use flexibly, when can supporting multi-path media file, shares each device node.
Four, the industry standard design being widely adopted based on DLNA, WiFi and Ethernet etc., complete compatible other industry equipment, especially electronic equipment for consumption.
Five, unified interface between software and hardware, without supporting various mass-memory units, can reduce the hardware cost of navigation amusement equipment in car.
Brief description of the drawings
Fig. 1 is structural representation of the present invention;
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
Embodiment
As shown in Figure 1, media sharing system in a kind of car based on DLNA, comprises navigation amusement equipment, personal consumption electronic equipment and router in the car of multiple employing DLNA protocol stack access networks.
Wherein, personal consumption electronic equipment comprises household consumption electronic equipment 4 and mobile consumer-elcetronics devices 3, and router is can be simultaneously or connect separately the router five of Wi-fi and Ethernet.Household consumption electronic equipment 4 is generally home media center etc., be connected with the amusement equipment 1,2 that navigate in car by router five, and mobile consumer-elcetronics devices 3 is generally smart mobile phone, panel computer etc., can, with household consumption equipment equally by being connected with the amusement equipment 1,2 that navigate in car in the mode of Wi-fi or Ethernet with router five, also can carry out point to point connect by the amusement equipment 1,2 that navigate in the mode of Wi-Fi Direct or ad-hoc and car.In car, in navigation amusement equipment 1 and other cars, navigate between amusement equipment 2, can connect by two kinds of patterns equally, be respectively the point-to-point mode of Wi-FiDirect or ad-hoc and the mode with Wi-fi or Ethernet by router.
In car, navigation amusement equipment comprise file system 8 and media player 7, and the major function of media player 7 is to realize the real-time broadcasting of Media Stream, and the major function of file system 8 is to obtain or media streams.In the time of media delivery, data-source device is obtained Media Stream by file system 8, after 6 encapsulation of DLNA protocol stack, send to target device, target device receives media stream data, after DLNA protocol stack 6 is resolved, play in real time by media player 7, or stored by file system 8.Wherein, DLNA protocol stack 6 comprises uPnP agreement, HTTP/RTP agreement, ICP/IP protocol, Wi-Fi agreement and Ethernet protocol.
Equipment of the present invention can connect i.e. use, and in the time that new equipment adds network, this equipment can be informed the DLNA function that it is realized, the information such as media formats and digital publishing rights of support to other equipment in network by DLNA protocol stack.In like manner, in the time having equipment deviated from network, also can inform this information to other equipment in local area network (LAN).
