Background
In the prior art, the number of input nodes for inputting the external video stream into the display device is generally the same as the number of output nodes in the display device, and the input nodes and the output nodes are in a one-to-one transmission relationship of the video stream, but when the number of the external video streams is huge, the display device is directly caused to be correspondingly provided with the same huge number of output nodes, and correspondingly bears larger processing pressure.
And secondly, the content display of the display devices requires the collaborative command of a plurality of command centers, and the display content of the master spliced wall is commonly shared and distributed to the slave spliced wall, and the pictures displayed on the master spliced wall are shared by the signal sources in a way-by-way mode by means of signal source sharing and are sent to other command centers through a network to realize sharing. However, the sharing mode has more limitations, on one hand, if the content displayed on the main splicing wall is more, the number of signal sources needing to be shared and transmitted is more, which is a great challenge to the internet bandwidth of the command center. On the other hand, the display pictures of the main splicing wall cannot be synchronized in real time in different places. When the picture of the main splicing wall is replaced, the picture remotely shared by the network in different places is manually replaced, and the picture cannot be synchronously watched in different places according to the layout position displayed by the main splicing wall.

Detailed Description
The drawings are for illustrative purposes only and are not to be construed as limiting the invention. For better illustration of the following embodiments, some parts of the drawings may be omitted, enlarged or reduced, and do not represent the actual product dimensions; it will be appreciated by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.
Example 1
The embodiment provides a display method of a screen sharing cloud platform, which is applied to a spliced wall comprising a plurality of display devices, such as a spliced display wall, a spliced display screen and the like. The method is improved based on the display process of the existing display equipment, so that the processing pressure of the video stream of the display equipment is reduced, and more efficient picture sharing display between the master splicing wall and the slave splicing wall can be realized.
As shown in fig. 1, the method comprises the steps of:
s110, inputting a plurality of input nodes into a first video stream and outputting the first video stream to a plurality of main output nodes of a main splicing wall;
the input node is a node through which an external video stream needs to flow when being input into the main splicing wall, is mainly responsible for signal acquisition, and converts the externally input video signal into a video stream signal with a specific network format to form a first video stream.
As shown in fig. 2, the number of input nodes is n, n is the same as the number of paths of external video stream input, and each input node processes one path of external input video stream.
In this embodiment, the main splicing wall is composed of a plurality of display devices, and the whole picture is formed by splicing the contents displayed by the plurality of display devices. The main splice wall means that the content displayed by the display device included in the main splice wall is displayed directly according to the first video stream, and the content displayed from the splice wall is obtained from the display content of the main splice wall. The first video stream may be transmitted to a main output node of the main splice wall through a data switching device (e.g., a switch, etc.) for network data switching. The data exchange device may also be a custom exchange device, and the transmission medium of the video stream is not limited to a network cable, but may also be an optical fiber, a coaxial cable, or the like.
And the main output node of the main splicing wall is responsible for decoding, converting, scaling, cutting and the like the video stream converted by the input node, and finally outputting the processed video stream to a sub-screen of the main splicing wall for display. After receiving the first video stream, each main output node outputs the received first video stream to one display device of the main splicing wall, each display device correspondingly displays video stream data, and the video stream data are spliced to form the whole display content of the main splicing wall. As shown in FIG. 2, the main output nodes A1 to Am correspond to the display devices A1 to Am of the main splice wall, respectively.
As shown in fig. 2, the number of main output nodes of the main splicing wall is m, and the number m of main output nodes and the number n of input nodes are not limited, when m > n, after receiving the first video stream, part of main output nodes need to be displayed in an enlarged manner when displayed on the corresponding display device, so that the picture of the main splicing wall is complete. When m < n, part or all of the primary output nodes receive at least two first video streams (each primary output node is shown in fig. 2 as receiving one first video stream by way of example only), and are displayed in the same display device after splicing. When m=n, one path of first video stream input by each input node can be correspondingly output to one main output node, and each main output node displays the one path of first video stream 1:1 on the corresponding display device, so that the video data is an optimal display scheme because the video data does not need to be enlarged or reduced.
S120, outputting first video streams input by a plurality of input nodes to a plurality of mirror image splicing nodes;
the first video stream may be transmitted to the mirror splice node through the data switching device.
S130, controlling each mirror image splicing node to form a second video stream according to at least one input first video stream;
in this step, the second video stream formed by the mirror image splicing node is a mirror image combined video stream of the first video stream, and each path of second video stream at least includes video data of the corresponding first video stream and a display position of the first video stream. The display position of the first video stream refers to a position where the first video stream is displayed in the main splice wall, and also a position of a display device that displays the first video stream.
The mirror image splicing nodes are arranged in the main splicing wall, after at least one path of first video stream is received, a second video stream is formed according to the received video stream data, the second video stream is a mirror image combined video stream of the first video stream, and each path of second video stream comprises the video data of the corresponding first video stream and the display position.
As shown in fig. 2, the number of mirror image splicing nodes is t, the maximum value of the number t of mirror image splicing nodes is the number m of main output nodes, when t is less than m, part or all of the mirror image splicing nodes receive at least two paths of first video streams (each mirror image splicing node is only exemplarily shown in fig. 2 to receive one path of second video stream), and the received first video streams are spliced to form one path of second video stream, at this time, the formed path of second video stream contains video data of the spliced first video stream and display positions thereof. When t=m, one path of first video stream input by each input node can be correspondingly output to one mirror image splicing node, and each mirror image splicing node forms one path of second video stream from the one path of first video stream, so that the first video stream is not required to be reduced or amplified, and the display is 1:1, and is an optimal display scheme.
S140, respectively outputting a plurality of paths of second video streams to a plurality of slave output nodes of the slave splicing wall;
as shown in fig. 2, when the master splice wall and the slave splice wall are in the same lan, the same data exchange device may be shared for data exchange, and thus, the second video stream may be transmitted to the slave output node of the slave splice wall through the data exchange device.
When the master splice wall and the slave splice wall are in different local area networks, the same data exchange equipment cannot be shared for data exchange, so as shown in fig. 3, the second video stream needs to be transmitted to the slave output node of the slave splice wall through the cloud service equipment. In a specific embodiment, the cloud service device includes a media gateway and a cloud platform, the second video stream is output to the media gateway, and the media gateway is used for providing authority management of the cloud platform on the second video stream, forwarding audio and video streaming media, mapping and converting IP of an internal network and an external network, and the media gateway can be controlled by a built-in client or be configured in a plurality of media gateways according to requirements. The media gateway transmits the received second video streams to the cloud platform, and a cloud server can be deployed at the cloud end by using the existing cloud platform network and used for forwarding control management, authority management, storage management, flow monitoring and the like of the video streams. And the cloud platform transmits the received second video stream to data exchange equipment in the same local area network as the slave splicing wall through a cloud platform network, and the second video stream is transmitted to the slave output node through the data exchange equipment.
In this step, each slave output node outputs the second video stream to the display device of the slave splice wall after receiving the second video stream. As shown in fig. 2, the number s of the slave output nodes is the same as the number of the display devices of the slave splice walls, and the master output nodes B1 to Bs respectively correspond to the display devices B1 to Bs of the master splice walls. If only one slave output node exists, namely only a single display device exists in the slave spliced wall, the display content of the slave spliced wall is consistent with the display content of the master spliced wall, and the sharing display of the master spliced wall and the slave spliced wall is realized.
In a specific embodiment, the number s of the secondary output nodes is not limited, and the maximum value s of the secondary output nodes may be the same as the number m of the primary output nodes, and when s < t, at least two paths of second video streams are received from the secondary output nodes (in fig. 2, each path of second video stream received from the secondary output nodes is only schematically drawn), and the position information of the received second video streams is displayed after being spliced. When s=t, each secondary video stream is received from the output node, and the secondary video stream 1:1 is displayed on the corresponding display device, so that the video data does not need to be enlarged or reduced, and therefore, the optimal display scheme is achieved.
In a specific implementation manner, in the method provided by the embodiment, time synchronization frames are embedded in the second video streams obtained after splicing, the spliced second video streams are mirror image combined videos of the first video streams, so that in order to coordinate mirror image combined video display steps, synchronization of pictures of the output second video streams is ensured, and finally, content displayed in each display device of the spliced wall is synchronized without tearing sense, and screen display of the spliced wall has integrity. Under the scene with higher requirement on time synchronization, the second video stream and other video streams can be displayed and synchronized by software and hardware in double guarantee by using coaxial cable serial connection through an external hard synchronization interface.
According to the method for displaying the screen sharing cloud platform, the mirror image splicing node arranged in the main splicing wall is utilized to process the first video stream input by the input node into the video data containing the corresponding first video stream and the second video stream at the display position, the video data and the second video stream are output to the slave output node, after at least one path of second video stream is received by the slave output node, the display can be directly carried out according to the content of the second video stream, even if the first video stream input by the input node is replaced, the display content of the slave splicing wall can be synchronously replaced by directly changing the content of the second video stream by means of the second video stream formed by the mirror image splicing node, the display can be directly carried out after the changed second video stream is received by the slave output node, and the picture real-time synchronization of the master-slave splicing wall is realized without manual picture replacement.
