Afterward understood before we go already some 5 companies sent the technical personnel to solve this problem were the idle work return, local project business is also badly battered, the headless fly is likely ordinary. But product supplier; It is said is seeks help hopelessly,the suspension
is left over 20% equipment fund estimate is also the recycling is hopeless, left Jiangxi quietly. Is everybody while the price the abyss of suffering, who in the attention technology, these questions also who the crime? In Chinese electron market;
Never lacks “the village in a mountainous area “two characters, the village in a mountainous area on behalf of the low in price, the quality is not only unstable, makes the labor not to be fine, represents without the service, does not have the authentication, does not have the technology, also has formed three non-product representatives the word. Because in the product quality,movement process
in the technology the very big investment, the small workshop type had not constituted the cost bottom, the natural market selling price is inexpensive, what village in a mountainous area-like sales model depending on is the rivers and lakes loyalty, the benefit enticement, gains the middle price difference by the fast expense's way to survive, is precisely the inexpensive procurement cost, many project business take risks under the high quota profit's obligation, the innumerable Small business set up one huge “the village in a mountainous area” the product to sell the empire, is nibbling the entire high-end demonstration domain the industrial chain.
Takes big strides representative who the electron (China) the Limited company takes the digital splicing profession, has located the high-end market, what depending on is by the new technical system enemy, serves the win, we should probably pay great attention each detail in so the tumultuous times, wins this backbone war by the specialty service attitude.
In the large screen splicing system, we gather very easily the focal point on the splicing unit, have never realized the genuine secret hero splices the controller; Splices controller's fit and unfit quality to decide entire large screen display system effect good and the badness directly, when the system often appears when the application halts, the figured screen, the expansion performance not strong, the image trailing, high clear signal race, cuts slanting, the picture flutter, our users only then truly pay attention to the question the root, finally will possess the question to lock on the splicing controller,drain reduces
only then regret already late. From the controller;
At present in the market condition presents four kind of splicing controllers, first replaces the PCI labor to control the type, second replaces embedded, the third generation is the FPGA pure hardware type, fourth replaces the bit type digit splicing controller. First replaces the PCI labor to control the type splicing controller; PCI REPLACEs the casette the principle of work is controls through the labor machine, the use multi-channel PCI computer motherboard, a part of PCI slot REPLACEion video frequency gathering card, other part of PCI slot REPLACEion video output card, among the input and the output constructs an operation and the processing station by CPU, by now set up a bench work to control the type controller.
His graphic processing principle is after the CPU operation female signal split M*N sub-video signal, carries on each sub-signal enlargement processing to transmit separately again for the splicing curtain wall on each corresponding unit, the display unit the signal which transmits the processor realizes on large screen's each display unit, but the resolution and the processing speed and correspond by computer CPU PCI card decision. Like; 1 720P place operating speed is 350MHz/nS,wedding dresses supplier but 10 720P place operating speed is 3.5MHz/nS, by now CPU operational capability big drop, because the labor controls machine the computing power is limited, a performance best labor controls type splicing most greatly also can only realize in the 1024*768 situation 4Х4 splicing, has limited the splicing unit number greatly.
Most early, although American RGB Corporation promotes has the pure hardware's 2*2 splicing control processor, can also carry on certain unit expansion through the cascade, but expansion ability is limited, the operation is inconvenient, the price is too expensive, what is popular is uses the pair (many) the channel output card to add the computer to make splicing, afterward to solve the multiwindow demonstration problem, American COLORGRAHIC Corporation promoted the multi-screen multiwindow splicing technology the EVOLUTION control card, to solve the window speed problem, what British Datapath Corporation had the graph acceleration was the specialized video frequency wall controller decides the body to manufacture the multi-screen card,
the RGB gathering card, the video frequency cut card, the British Datapath multi-screen card processing controls machine the way to be popularMany years, if the same year had the representative sea Pu prestige splicing controller. In order to break through the PCI slot data exchange bottleneck, had presented the first floor special-purpose main line exchange technology, enhanced the data bandwidth to each 8Gb/s, but first replaced the PCI labor to control the type splicing controller CPU handling ability serious restriction splicing scale, therefore also presented the distributional processing system, and with many processors, the universal network connection, let each processor be responsible for not many splicing units, connected again through the network the whole.
