Based on the above structure, various embodiments of the signal transmission method of the present invention are proposed.
The invention provides a signal transmission method.
Referring to fig. 2, fig. 2 is a flowchart illustrating a signal transmission method according to a first embodiment of the present invention.
In the present embodiment, an embodiment of a signal transmission method is provided, and it should be noted that although a logical order is shown in the flowchart, in some cases, the steps shown or described may be performed in an order different from that here.
In this embodiment, the signal transmission method is applied to a video matrix system, where the video matrix system includes n distribution selection boards, n first couplers, n second couplers, a bridge board, and n switch boards, the first couplers and the second couplers are disposed in the bridge board, the first couplers are electrically connected to the second couplers, the distribution selection boards are connected to the first couplers in a one-to-one correspondence, and the switch boards are connected to the second couplers in a one-to-one correspondence, and the signal transmission method includes:
step S10, acquiring N paths of first video signals through the input module in each distribution selection board, and converting the first video signals into second video signals.
The distribution selection board comprises an input module and an output module, wherein the input module is used for receiving a first video signal, the number of paths of the first video signal can be represented as N paths, and N is a positive integer. The first video signal has to be converted into a signal supported by the video matrix system, i.e. the second video signal, to be transmitted in the video matrix system. And converting the N paths of first video signals to obtain N paths of second video signals.
Step S20, according to a preset transmission path, sending the second video signal to a switch chip corresponding to the transmission path in the switch board sequentially through the first coupler and the second coupler in the bridge board, and switching the received second video signal through the switch chip.
The preset transmission path refers to a line connection mode among hardware in the video matrix system. The distribution selection board is connected with the first couplers in a one-to-one correspondence manner, each distribution selection board corresponds to one first coupler, each first coupler corresponds to one distribution selection board, the switching board is connected with the second couplers in a one-to-one correspondence manner, each switching board is connected with one second coupler, each second coupler is connected with one switching board, the first couplers and the second couplers are electrically connected, according to a preset transmission path, the second video signals in the distribution selection board are sent to the switching chip in the switching board through the first couplers and the second couplers in the bridge board in sequence, the switching chip corresponds to the transmission path of the received second video signals, and it can be understood that when the transmission paths of the second video signals are different, the switching chips receiving the second video signals are different. The bridge board provides sufficient space for the video matrix system to facilitate the connection of wires between the various hardware.
And after the switching chip receives the second video signal, switching the second video signal to determine that the video of the second video signal is displayed on the target LED screen.
Further, the video matrix system further includes a control platform, the control platform is connected to the switch board, and the step of switching the received second video signal in the switch board includes:
step a, controlling the control platform to visually display the exchange board to exchange the processing process of the second video signal.
The control platform can control and display the whole process of conversion of the first video signal, transmission and exchange of the second video signal.
Further, step S20 is preceded by:
b, according to the expansion multiple x of the video matrix, the distribution unit in each distribution selection board copies the number of paths of the second video signal to the product number multiple of the original n and x, so that each distribution selection board obtains the second video signal of which the number of paths is the product number multiple of the original n and x.
The expansion multiple of the video matrix is the expansion multiple of the number of the distribution selection boards in the video matrix system, and the expansion multiple of the video matrix is the expansion multiple of the switching boards because the number of the distribution selection boards in the same video matrix system is the same as that of the switching boards. According to the expansion multiple x of the video matrix, the distribution unit in the distribution selection board copies the N paths of second video signals into the original product number multiple of N and x, each distribution selection board obtains the N paths of second video signals of which the product number is multiple of N and x, namely, the N paths of second video signals are multiplied by x N paths, and the N and x are positive integers.
Each distribution selection board has N × x N channels of second video signals, and the video matrix system should theoretically select a switch chip of a size capable of processing N × x N channels of video signals in order to complete processing of N × x N channels of video signals, but if the value of N × x N is too large, when such a large switch chip is not present, N × x chips of a size capable of processing N channels of video signals can be selected and used, and each switch chip processes N channels of second video signals, so that processing of N × x N channels of second video signals can be realized. Each predetermined transmission path may transmit N channels of the second video signal, and then N × x N channels of the second video signal require N × x predetermined transmission paths. Referring to fig. 3, fig. 3 is a schematic structural diagram of the video matrix system of the present embodiment when n is 2 and x is 2, the preset transmission path can be seen from fig. 3, the video matrix system represented by fig. 3 is extended by 2 times from the video matrix system with n being 2, and the video matrix system with n being 2 is shown in fig. 4. The bridge board also provides enough space for the expansion of the video matrix system so as to facilitate the connection of lines between various hardware in the expanded video matrix system.
When N is 2 and x is 2, the output interface of each first coupler is electrically connected with the input interface of each second coupler in a one-to-one correspondence manner, the output interface of each second coupler is electrically connected with the input interface of each first coupler in a one-to-one correspondence manner, and each input interface receives N paths of video signals from the output interface corresponding to the input interface.
Further, the first couplers include an input interface and an output interface, the second couplers include an input interface and an output interface, the output interface of the first coupler is electrically connected with the input interface of each of the second couplers, and the output interface of the second coupler is electrically connected with the input interface of each of the first couplers, step S20 includes:
step S21, sending every N paths of the second video signals in the distribution selection board to the first coupler according to a preset transmission path, and sending the second video signals to an input interface of the second coupler through an output interface of the first coupler.
At this time, the number of paths of the second video signals contained in each distribution selection board in the video matrix system is N × x N, if each LED display screen of the video matrix system is to display videos corresponding to N paths of the first video signals acquired by all the distribution selection boards, N × x N paths of the second video signals in each distribution selection board need to be sent to the first coupler, and then the second video signals in each N path are sent to the input interface electrically connected with the output interface of the first coupler in N × x second couplers through the output interface of the first coupler, so that each second coupler receives the second video signals sent by all the distribution selection boards. It is understood that each second connector receives the second video signals by N × x × N channels.
Step S22, after the second connector receives the second video signal, send the second video signal to a switch chip in the switch board corresponding to the transmission path.
When each second connector receives the second video signal, the second video signal is sent to the switching chip of the switching board corresponding to the second connector, the switching chip corresponds to a transmission path for transmitting the second video signal, and each switching chip can process N paths of the second video signal.
Further, the switch board includes switch chips of the product number of n and x, and the switch chips are used for realizing switching of the second video signals received by the switch chips.
When the switch board receives N × x × N channels of second video signals, N × x switch chips capable of processing N channels of second video signals are required, and each switch chip only receives the second video signals transmitted by the transmission path connected thereto. After each switching chip receives the N paths of second video signals, the switching chip can be controlled to switch the N paths of received second video signals so as to control the display positions of the N paths of video signals on the LED display frequency.
And step S30, sending the exchanged second video signals to the output modules of the distribution selection board respectively.
After the exchange of the N paths of second video signals is completed through the exchange chip, the exchanged second video signals are sent to all the first couplers through the connection relation between the output interfaces of the second couplers and the input interfaces of the first couplers, and the second video signals received by the first couplers are sent to the output plates in the corresponding distribution selection boards.
The invention can realize that one exchange board exchanges multiple N paths of second video signals by increasing the number of the exchange chips in the exchange board, and then respectively sends the exchanged second video signals to the output modules of the distribution selection boards, and the invention can respectively process multiple paths of video signals transmitted from different transmission paths through a plurality of exchange chips with smaller specifications, the processing capacity of the video signals is further improved by increasing the number of the switching chips and the number of the transmission paths, and the requirement of a super-large-scale video matrix is met.
Further, a second embodiment of the signal transmission method of the present invention is proposed.

And d, serializing the first sub video signal into a second video signal through a serializing unit in the input module.
