Description

AVM-NODE interconnects node

Technical field

It the utility model is related to multimedia equipment technical field, and in particular to AVM-NODE interconnects node.

Background technology

The node that interconnects employ digital audio/video encoding and decoding technique, be related to TCP/IP communication, UDP communication, AVMedia works software engineering, resolution ratio self-adaptive processing, HDMI inputs and output treatment technology etc.；Interconnect with Realized toward using simulation line stretcher or fiber optical transceiver combination video matrix, traditional mode is in upgrading extension by certain Limitation, it is necessary to fixed video matrix forms switching as support and interconnected, can not gradually meet that the interconnection of multizone is mutual It is logical, it would be highly desirable to improve.

Utility model content

The defects of the purpose of this utility model is to be directed to prior art and deficiency, there is provided a kind of simple in construction, design is closed Reason, AVM-NODE easy to use are interconnected node, and coding and decoding is carried out simultaneously, access network, are not limited by distance System, arbitrarily extensible upgrading, multiple spot interconnect, and show multiple images, realize more complicated application demand and function, practicality It is stronger.

To achieve the above object, the technical solution adopted in the utility model is：It includes asic chip, acquisition module, turned Change the mold block, coding module, decoder module, mixed-media network modules mixed-media and interface module；Described asic chip, acquisition module, modular converter, Coding module, decoder module, mixed-media network modules mixed-media and interface module are arranged in casing；And acquisition module, modular converter, coding mould Block, decoder module, mixed-media network modules mixed-media and interface module are connected with asic chip.

Further, described acquisition module includes HDMI acquisition modules and audio collection module.

Further, described modular converter includes conversion HDMI module and transducing audio module.

Further, described interface module includes USB interface, RS232/485 serial signals remote interface, dry contact control Input interface, TCP/IP interfaces, WEB interfaces, audio input/output interface and HDMI input/output interfaces processed.

Further, described HDMI input/output interface compatibilities DVI.

After said structure, the utility model has the beneficial effect that：

1st, solve the problems, such as that multiple audio frequency and video autonomous systems need to interconnect, traditional mode needs to intend by drawing-die Circuit is realized；

More exchange device is needed when the 2nd, solving the problems, such as legacy system dilatation, now needs increase to interconnect node；

3rd, solve when interconnecting, audio-visual synchronization, the problem of signal bandwidth is too big, now only need 4 ~ 10M to meet The application interconnected is received and dispatched all the way；

4th, solve the problems, such as remote control, can be thrown by transparent transmission RS232/485 signal, remote control camera Shadow machine, television set etc..

Brief description of the drawings

, below will be to embodiment in order to illustrate more clearly of the utility model embodiment or technical scheme of the prior art Or the required accompanying drawing used is briefly described in description of the prior art, it should be apparent that, drawings in the following description are only It is some embodiments of the utility model, for those of ordinary skill in the art, before creative labor is not paid Put, other accompanying drawings can also be obtained according to these accompanying drawings.

Fig. 1 is system construction drawing of the present utility model.

Fig. 2 is workflow diagram of the present utility model.

Description of reference numerals：

Asic chip 1, acquisition module 2, modular converter 3, coding module 4, decoder module 5, mixed-media network modules mixed-media 6, interface module 7。

Embodiment

The utility model is further described below in conjunction with the accompanying drawings.

Referring to as depicted in figs. 1 and 2, the technical scheme that present embodiment uses is：It includes asic chip 1, adopted Collect module 2, modular converter 3, coding module 4, decoder module 5, mixed-media network modules mixed-media 6 and interface module 7；Described asic chip 1, adopt Collection module 2, modular converter 3, coding module 4, decoder module 5, mixed-media network modules mixed-media 6 and interface module 7 are arranged in casing；And adopt Collection module 2, modular converter 3, coding module 4, decoder module 5, mixed-media network modules mixed-media 6 and interface module 7 are connected with asic chip 1.

Further, described acquisition module 2 includes HDMI acquisition modules and audio collection module.

Further, described modular converter 3 includes conversion HDMI module and transducing audio module.

Further, described interface module 7 includes USB interface, RS232/485 serial signals remote interface, dry contact Control input interface, TCP/IP interfaces, WEB interfaces, audio input/output interface and HDMI input/output interfaces.

Further, described HDMI input/output interface compatibilities DVI.

The operation principle of present embodiment：HDMI input can directly gather HDMI+ audio stereo signals, pass through DDR is cached, and cache-time can be set by program, afterwards with standard H.264 coded format, into Ethernet switch, can be passed Arbitrary reception decoding end is sent to, realizes that interconnects is transmitted into LAN；

The AVM-NODE nodes that interconnect can receive the H.264 video/audio signal from local area network standard, establish connection Afterwards, video data is first cached in DDR, decoded with H.264 reference format, after decoding can to further four dividing processing or Display processing all over the screen, then form conversion is done to DDR cachings, finally by digital video+digital sound of HDMI outputting standard Frequency signal；Meet the application scenarios that interconnect of more Classrooms and more meeting sharing videos；

AVM-NODE interconnect node delay from HDMI input codings enter LAN to decoding output HDMI processing Process needs to use 10 two field pictures caching, needs 16.6ms per two field picture, 10 frames one share 170ms delay, if removing contracting Put processing, delay can be maintained at 150ms or so, and two kinds of delays do not influence for the different spaces application scenarios that interconnect.

After said structure, present embodiment has the beneficial effect that：AVM-NODE described in present embodiment Interconnected node, and coding and decoding is carried out simultaneously, is accessed network, is not limited by distance, arbitrarily extensible upgrading, multiple spot is mutual Join intercommunication, show multiple images, realize more complicated application demand and function, practicality is stronger, and the utility model has structure Simply, it is reasonable to set, the advantages that low manufacture cost.

It is described above, only to illustrate the technical solution of the utility model and unrestricted, those of ordinary skill in the art couple The other modifications or equivalent substitution that the technical solution of the utility model is made, without departing from technical solutions of the utility model Spirit and scope, it all should cover among right of the present utility model.
