Abstract
The utility model discloses an it is wireless from network deployment twine courseware information transmission means, this it is wireless from network deployment twine courseware information transmission means include a transmitting element and a receiving element, and wherein this transmitting element includes at least that audio/video data acquires module, coding module and WIFI emission module, and receiving element includes WIFI receiving module, decoder module and audio/video data output module at least, the utility model discloses a WIFI wireless communication is from the networking technology, and dispensing device and receiving arrangement automatic connection web formation send the demonstration video and the acoustic information of computer for a plurality of display device through radio signal, realize the wireless transmission and the distribution of courseware information.
Description
[technical field]
The utility model relates to electronic technology field, refers to a kind of wireless ad hoc network courseware-related information transmitting device especially.
[background technology]
The occasion of information display system being applied in auditorium, Conference Hall etc. and needing the occasion of long range propagation signal or build temporarily, video and audio content is often needed to be sent to multiple receiving system, existing technical scheme may be confined to the cable transmission network previously laid, or need to arrange multiple playing device (as computer etc.) coordinate with corresponding display unit (display or projecting apparatus) and realize the information displaying of diverse location, this realizes comparatively complicated, high cost.
[utility model content]
The purpose of this utility model is to provide a kind of wireless ad hoc network courseware-related information transmitting device, in order to solve in prior art need to rely on cable transmission network or configure the implementation that multiple playing device causes complicated, the technical problem of high cost.
For achieving the above object, implement wireless ad hoc network courseware-related information transmitting device of the present utility model and comprise a transmitting element and a receiving element, wherein this transmitting element at least comprises audio, video data acquisition module, coding module and WIFI transmitter module, and receiving element at least comprises WIFI receiver module, decoder module and audio, video data output module.
According to above-mentioned principal character, this transmitting element and a receiving element are provided with USB interface.
According to above-mentioned principal character, this transmitting element is provided with HDMI.
Compared with prior art, implement wireless ad hoc network courseware-related information transmitting device of the present utility model and utilize WIFI wireless telecommunications ad hoc network, dispensing device and receiving system connect into net automatically, the display video of computer and acoustic information are sent to multiple display device by wireless signal, realizes wireless transmission and the distribution of courseware-related information.
[accompanying drawing explanation]
Fig. 1 is the system framework schematic diagram implementing wireless ad hoc network courseware-related information transmitting device of the present utility model.
[embodiment]
Refer to shown in Fig. 1, implement wireless ad hoc network courseware-related information transmitting device 1 of the present utility model and comprise a transmitting element and a receiving element, wherein this transmitting element at least comprises audio, video data acquisition module, coding module and WIFI transmitter module, and receiving element at least comprises WIFI receiver module, decoder module and audio, video data output module.
This wireless ad hoc network courseware-related information transmitting device gathers video information and audio-frequency information (being such as stored in the courseware in a courseware computer or server) by the audio, video data acquisition module of dispensing device, can be inputted by HDMI (containing audio frequency) or VGA signal+audio frequency when it is specifically implemented, the vision signal gathered adopts MJPG to encode by coding module, reduce the loss of detail of signal as far as possible, and audio frequency adopts AAC coding, make the time delay of signal minimum, and can Discarded Packets compensation, ensure the continuous of signal.In the specific implementation, this transmitting element or receiving element all can be provided with USB interface, power by USB interface when being connected with courseware computer or external display device, thus can simplify application difficulty.
Receiving element is connected with transmitting element automated wireless by WIFI receiver module, receive courseware video data encoder and the coded audio data of sending unit, decoder module is by after audio/video decoding, courseware Audio and Video is passed to outside display device, as projector, TV etc. by video output.
By above-mentioned structure, implementing wireless ad hoc network courseware-related information transmitting device of the present utility model is the collection that a kind of WIFI of utilization ad hoc network realizes courseware Audio and Video, and adopts wireless mode to connect, and can realize the Signal transmissions of point to multi--point.Further, the resolution of the vision signal of all right automatic decision input of transmitting element, the resolution of adjustment collection signal automatically.Moreover transmission, receiving element adopt WIFI ad hoc network, complete certainly being dynamically connected of networking, do not rely on third party AP equipment, equipment from being dynamically connected by algorithm, is arranged without the need to user and selects, and coding audio-visual stream adopts P2P distribution technology, realizes the Signal transmissions of point to multi--point.Coding audio-visual stream adopts the QOS quality control of standard RTP bag tunneling and RTCP simultaneously.In the specific implementation, transmitting and receiving unit all can adopt the low-power consumption based on ARM be applied in smart mobile phone, high-performance central processor, thus reduces the difficulty implemented, and is more conducive to promote.
By implementing wireless ad hoc network courseware-related information transmitting device of the present utility model and mobile terminal (as portable computer) combines, can form a multi-hop, provisional, from create (self-Creating), self-organizing (Self-Organizing), Self management (Self-Administering) system, do not rely on default infrastructure and set up temporarily, and mobile terminal has routing function, arbitrary network topology can be formed by wireless connections, and can work independently, also can be connected with network or cellular radio.
Compared with prior art, the utility model adopts WIFI ad hoc network, and tool has the following advantages: (1) bandwidth is high, supports that 802.11b/g/n supports the communication speed of 54Mbps; (2) network self-healing function is very strong; (3) cost is low, a large amount of device adopting consumer electronics; (4) need not connect up, arrange net conveniently, be particularly suitable for the occasions such as the Conference Hall temporarily built; (5) extended capability is strong.
Be understandable that; for those of ordinary skills; can be equal to according to the technical solution of the utility model and inventive concept thereof and replace or change, and all these change or replace the protection range that all should belong to the claim appended by the utility model.
