In the LED display systems on the market at present, separate encoding devices, decoding devices, transmitting cards and the like are required, and video signals can only be processed by the external devices and then displayed on a screen. As shown in fig. 1, a video signal of a signal source 101 is encoded by an encoding device 102 and then transmitted to a switch 103, then the switch 103 converts the video signal into a unified network media stream format and transmits the unified network media stream format to a decoding device 104, the decoding device 104 decodes the video signal and then splices the video signal, and the spliced video signal is transmitted to a display screen 105 for display through a network cable. But for large LED display systems, especially involving multi-level video codecs, splice processors, sender boxes, these device numbers, functions, capabilities, interface types are not the same, and incompatibility problems may occur. The display system has a high failure rate because of a large number of devices and complicated lines.

In view of this, some embodiments of the present disclosure may provide a display system to solve the problem that the LED display screen needs a device such as a splice processor and a sending box.

As shown in fig. 2, a schematic structural diagram of a display system according to an embodiment of the present disclosure is shown.

Specifically, the network switch is a bridge for transmitting video signals from the signal source device 201 to the LED display device 203, and converts video signals with different formats into a unified network media stream format through the switch, and transmits the unified network media stream format to the LED display device 203 in communication connection with the network switch, so as to avoid inconsistent signal formats and resolutions.

The LED display device 203 is communicatively connected to the network switch 202. In some embodiments, the LED display device 203 is configured with a network card or portal to communicate video (and audio) data with the network switch 202 via a network line communication connection.

The LED display device 203 includes at least one sub-display screen 213. In the example of fig. 3, the LED display device 203 may include a plurality of sub-display screens, that is, a large screen formed by splicing the plurality of sub-display screens 213. Alternatively, in other examples, the LED display device 203 may include only one sub-display screen.

In this embodiment, a separate distributed processing unit 2131 is configured in each sub-display screen 213 of the LED display device 203, so that the receiving, decomposing, parsing, and transmitting of the audio/video signal is no longer a single-core process and a serial process, but a multi-core parallel process. The distributed processing unit 2131 can re-divide and stage the first video signal in the network streaming media format to achieve important display performance of the display screen with better algorithm and faster processing efficiency, such as: low brightness, high contrast, high refresh rate, high gray scale, etc., greatly enhancing the processing capability of the system. In some embodiments, the predetermined format of the second video signal may be, for example, a DVI signal.

The LED display device 203 is exemplarily shown to include a plurality of sub-display screens 213 spliced with each other, each sub-display screen has a structure as shown in fig. 3, and the distributed processing units 2131 of each sub-display screen 213 are connected in a communication manner; each of the sub-displays 213 further includes a receiving card 2132 and a driving circuit 2133; the distributed processing unit 2131 is communicatively connected with a receiver card 2132; the receiving card 2132 is connected to the driving circuit 2133 in a communication manner; the driving circuit 2133 is connected between the receiving card 2132 and the display unit 2134 in a communication manner; each of the distributed processing units 2131 is configured to encode the first video signal in the respective network streaming media format and then decode the encoded first video signal into the second video signal in the preset format, and further utilize the communication connection between the distributed processing units 2131 of each of the sub display screens 213 to perform the mutual splicing processing on the respective second video signals, and transmit, through the receiving card 2132, the spliced set of second video signals to the driving circuit 2133 for displaying to the display unit 2134.

According to the embodiment, the coding and decoding equipment and the splicing equipment are integrated into the distributed processing units of the sub-display screen, so that the problem that the LED display screen can be lightened only by connecting equipment such as an external encoder, a decoder and a sending card in the prior art is solved, namely, in the scheme of the embodiment, a signal source is connected with a computer and a switch through a network or a video line, and the use requirement of the screen can be met. The cost is reduced, the problem that the decoder is not compatible with external equipment in the prior related art is avoided, and in addition, the complexity of field environment construction and the later system maintenance cost can be reduced.

In some embodiments, the LED display device 203 is formed by stitching a multiple of 4 sub-displays, such as fig. 4, 8 or more sub-displays, etc. Alternatively, in another embodiment, the LED display device may be formed by splicing 9 sub-display screens. The number of specific sub-displays may be determined according to the size of the sub-displays and the required overall length and width dimensions of the LED display device.

In some embodiments, as shown in fig. 4, the display system further includes a signal source control device 204, where the signal source control device 204 is respectively communicatively connected to the network switch 202 and the LED display device 203, and is configured to search for at least one target LED display device 203 that is available for display, so as to transmit the first video signal to the selected target LED display device 203 through the network switch 202.

In some embodiments, the number of the signal source devices 201 is plural, and the signal source control device 204 further controls the outputs of the plural signal source devices 201.

In order to better explain the above embodiments, an example will be described in detail below. Firstly, a network switch uniformly converts SDI signals sent by various accessed signal source devices into network streaming media format signals; and then the signal source control equipment selects one LED display device from at least one LED display device which is in communication connection with the signal source control equipment as a target LED display device, and transmits the SDI signal in the network streaming media format to the target LED display equipment in real time, wherein the target LED display equipment is formed by splicing 8 sub-display screens, and each sub-display screen is provided with a distributed processing unit, a display unit and a transmitting card. And the distributed processing unit sets an output node, receives the SDI signal in the network media stream format, encodes and decodes the SDI signal, simultaneously completes splicing and combining processing of multiple paths of video signals, converts the video signal into a DVI signal which can be identified by the driving circuit, and finally drives the display unit in the LED display setting to display according to the DVI signal.
