Abstract
The invention relates to a distributed matrix switching system comprising a signal source, at least one input node, a network switch, at least one output node, and a display device that are connected successively. After an image signal of the signal source is inputted into the input node, the input node compresses and encodes the image signal into network data and then transmits the network data to the network switch. After receiving the network data via the network switch, the output node decompresses, zooms, and cuts the network data and then outputs processed data to the display device. Then, the display device displays images. Compared with a product in the prior art, the distributed matrix switching system has advantages of good expansibility, convenient maintenance, and real-time signal transmission.
Description
Technical field
The present invention relates to a kind of transmission of video and Display Technique, especially relate to a kind of distributed matrix switched system.
Background technology
Along with the development of video-splicing Display Technique, large-screen splicing video wall has obtained increasing favor with its high definition, color effect true to nature, large picture at present.The high-resolution of splicing large screen can be passed on more information, can meet many-sided demands such as real-time monitoring, command scheduling, report displaying, advertising, has obtained large-area universal use.
Existing tiled display technology, is achieved in the following ways conventionally: the image information of multipath signal source is transferred to a concentrated matrix switcher by professional cable, and matrix switcher is sent on corresponding mosaic screen by cable again.This reality technology mainly contains following several defect: whole engineering can not arbitrarily increase the quantity of signal source and the quantity of mosaic screen; To use many professional signal cables (quantity of cable is relevant to the quantity of the quantity of signal source and mosaic screen), this will affect the difficulty of construction and the overall appearance degree of project of engineering greatly; The transmission range of specialty cable is limited; Once matrix switcher breaks down, will affect whole system.
Summary of the invention
Object of the present invention is exactly that a kind of favorable expandability, easy to maintenance, the distributed matrix switched system that can realize signal real-time Transmission are provided in order to overcome the defect that above-mentioned prior art exists.
Object of the present invention can be achieved through the following technical solutions:
A distributed matrix switched system, comprises signal source, at least one input node, the network switch, at least one output node and display device, and described signal source, input node, the network switch, output node, display device connect successively;
The picture signal of signal source is input to after input node, by input node, compress, be encoded into network data and send to the network switch, output node receives after network data by the network switch, to network data decompress, convergent-divergent cutting processes, and the data after processing are exported to display device, by display device, carry out image demonstration.
Each input node and each output node all have independently IP.
The described number of input node is identical with the number of signal source.
The number of described output node is identical with the number of display device.
In described output node, be provided with the allocating cache chip that stores image scaling cutting specification, output node carries out convergent-divergent trimming operation according to image scaling cutting specification to image.
Also comprise computer, described computer is connected with output node by the network switch, and computer sends output node enabling signal by the network switch, and sends image scaling cutting specification to output node.
Described input node and output node carry out exchanges data by ICP/IP protocol.
Described input node and output node carry out exchanges data by udp protocol.
Compared with prior art, Adoption Network distributed architecture of the present invention, all input nodes and output node work alone, and can be good at expansion and maintenance work (only needing to change corresponding failure node); Because the present invention has used network transmission technology, realized the long-distance transmissions of signal simultaneously.
