Description

Technical Field

[0001] The present invention relates to the field of distributed display and control technology, and in particular to a method, device, equipment and storage medium for determining a data transmission type. Background Art

[0002] The network distributed splicing processing system belongs to the third generation of image splicing system, which connects image acquisition, image transmission and image display through a digital network. The network is used as a large-screen signal transmission carrier. The structure allows the input and output nodes to be geographically dispersed, which has great flexibility and scalability. The system has functions such as multi-point sharing of image signals, network image access / output, and mobile terminal preview control. Each screen in the large screen of the network distributed splicing processing system is connected to a distributed output node. When the signal of the input node needs to be displayed in full screen on the large screen, the input node needs to send the signal to each output node. The encoded signal is not actually the same size for each frame, and the sending rate is actually uneven in a short time. For example, H264 and H265 are particularly large in I frames, while other frames are relatively small. If there are many small screens that make up the large screen, that is, there are many output nodes, in this case of one-to-many input and output, when sending I frames, the instantaneous rate is very large, which may exceed the switch load and cause packet loss.

[0003] Most distributed display and control systems use unicast or multicast when transmitting video streams. The advantage of unicast is that when the display and control system software is used to control the large screen window opening operation, the large screen responds quickly and the video comes out quickly. However, if the large screen uses more splicing screens, the distributed output nodes are 1:1 with the splicing screens, that is, there are many distributed output nodes. When displaying the distributed input node signal, the distributed input node must send each frame of data to each distributed output node separately. This causes a large network bandwidth, which puts a lot of pressure on the network of the entire system. When running for a long time, it is easy to lose packets and video freezes. When using multicast, the input node and the output node are added to the same group. The input node video stream only needs to send data to the group, and the output node receives data through the group. This greatly reduces the network burden, but multicast has a specific feature, that is, it takes a certain amount of time from joining to receiving data. Therefore, when using the display and control software for window opening operations, the large screen will respond slowly, the video will come out later, and the overall experience is not good. Summary of the invention

[0004] The present invention provides a method, device, equipment and storage medium for determining data transmission type, so as to solve the problems of easy packet loss and video freeze when using unicast to transmit data and large bandwidth and poor experience when using multicast to transmit data.

[0036] Embodiment 1

[0037] Figure 1 is a flowchart of a data transmission type determination method provided according to Embodiment 1 of the present invention. This embodiment is applicable to the situation of data transmission type determination. This method is applied to an output node. This method can be executed by a data transmission type determination device, and the data transmission type determination device can be implemented in the form of hardware and / or software. The data transmission type determination device can be integrated in any electronic device providing the data transmission type determination function. As Figure 1 shown, the method includes:

[0038] S101. Receive a window opening instruction.

[0039] Among them, the window opening instruction carries the identification information of the input node.

[0040] In this embodiment, the data transmission type determination method is mainly used in a distributed display control system.

[0041] It should be noted that the distributed display and control system includes at least one output node, at least one input node, a high-performance switch supporting multicast, and a computer installed with distributed broadcast control software.

[0042] Among them, the input node, the distributed output node, and the computer installed with distributed broadcast control software are all connected to the high-performance switch supporting multicast through network cables.

[0043] Among them, the distributed broadcast control software controls the entire distributed display and control system, including video display on the large screen, sound playback, and electrical switch control of the entire environment. The distributed broadcast control software performs window opening operations (the window opening operation is to project the video signal of the input node onto the large screen for display), and issues window opening instructions to the output node.

[0044] Among them, the high-performance switch supporting multicast must support multicast and can be configured. Only in this way can this data transmission type determination method take effect.

[0045] Among them, the input node is connected to the video output signal device through an HDMI (High Definition Multimedia Interface) or DVI (Digital Visual Interface) video cable. The video output signal devices include computers, conference hosts, and NVRs (Network Video Recorders), etc. The video signals output by these devices are collected and encoded through the video cable. The output node is connected to the video display device through an HDMI or DVI video cable, which means that each output node is connected to a small screen in the large screen. After receiving the window opening instruction, it decodes the video data and cuts and stretches the corresponding image on the corresponding screen for display according to the instruction, so as to stitch together a complete image. The video display device generally refers to an LCD (Liquid Crystal Display) or an LED (Light Emitting Diode).

[0046] Among them, the data transmission between the input node and the output node uses the UDP (User Datagram Protocol) protocol.

[0047] It should be noted that in the distributed display and control system, instructions and data are both transmitted through the network. Therefore, the input node, the output node, and the computer where the distributed broadcast control software is located all need to be connected to the switch in the same network.

[0048] Exemplarily, the identification information of the input node may be the IP address of the input node.

[0049] During the actual operation process, the distributed broadcast control software uses the configured project file to obtain the input node, output node, and the splicing situation of the large screen, etc. When implementing the window opening action of displaying the video encoded by the input node on the large screen, the window opening instruction will be sent to the output node corresponding to the large screen.

[0050] Specifically, the output node receives the window opening instruction, where the window opening instruction carries the identification information of the input node, the display position of the window, and display parameters, etc.

[0051] S102. Send a request stream instruction to the input node according to the identification information of the input node.

[0052] In this embodiment, the request stream instruction may be an instruction sent by the output node to the input node for requesting the input node to send data.

[0053] Specifically, after the output node receives the window opening instruction sent by the distributed broadcast control software, it sends a request stream instruction to the input node.

[0054] S103. Obtain the current sending duration corresponding to the request stream instruction.

[0055] It should be noted that the current sending duration may be the duration between the moment when the output node sends the request stream instruction to the input node and the current moment.

[0056] Specifically, the current sending duration corresponding to the output node sending the request stream instruction to the input node is detected in real time.

[0057] S104. Determine the data transmission type according to the current sending duration and the preset unicast sending duration.

[0058] Among them, the preset unicast sending duration may be pre-set by the user, and it is the duration for the input node to send data to the output node through the unicast transmission data transmission method. The specific duration value of the preset unicast sending duration is not limited in this embodiment. Preferably, the preset unicast sending duration may be the duration when the output node joins the multicast group formed by the input node. Exemplarily, the preset unicast sending duration may be several seconds for example.

[0059] In this embodiment, the data transmission type may be divided into unicast type and multicast type.

[0060] Specifically, the current sending duration and the preset unicast sending duration are compared in real time, and the data transmission type is determined according to the comparison result of the current sending duration and the preset unicast sending duration.

[0061] The technical solution of the embodiment of the present invention receives a window opening instruction, where the window opening instruction carries the identification information of the input node, sends a request stream instruction to the input node according to the identification information of the input node, obtains the current sending duration corresponding to the request stream instruction, and determines the data transmission type according to the current sending duration and the preset unicast sending duration, solving the problems of easy packet loss and video freezing when using unicast to transmit data and large bandwidth and poor experience when using multicast to transmit data, achieving the beneficial effects of enabling the large screen to respond quickly, generate images quickly, improving the user experience, and at the same time reducing the network bandwidth and making data transmission more stable.

[0062] Optionally, sending a request stream instruction to the input node according to the identification information of the input node includes:

[0063] Determining the port information of the input node according to the identification information of the input node.

[0064] Among them, the port information of the input node may be the attribute information of the port unicast-bound by the input node, and the attribute information may be, for example, port address information.

[0065] Specifically, when the input node starts, it unicasts and binds to a specified port, and the output node can determine the port information of the input node according to the identification information of the input node carried in the window opening instruction.

[0066] Sending a request stream instruction to the input node according to the port information of the input node.

[0067] Specifically, when the distributed control software implements window opening, it publishes the window opening instruction to the output node, and after receiving the window opening instruction, the output node sends a request stream instruction to the port unicast-bound by the input node.

[0068] Optionally, the request stream instruction carries the port information of the output node.

[0069] In the actual operation process, the output node binds a port for receiving instructions and a port for receiving data when it starts. Among them, the port information of the output node may be the attribute information of the port used by the output node to receive data, and the attribute information may be, for example, port address information.

[0070] After receiving the window opening instruction, it further includes:

[0071] Sending the port information of the output node to the input node so that the input node generates a multicast address according to the port information of the output node and the identification information of the input node.

[0072] It should be noted that the multicast address may be the address of the multicast generated by the input node according to the port information of the output node and the identification information of the input node.

[0073] Specifically, after receiving the window opening instruction, the output node sends the port information of the output node to the input node, so that the input node generates a multicast address according to the port information of the output node and the identification information of the input node. The output node calculates a unique multicast address through a certain algorithm according to the identification information of the input node carried in the window opening instruction, and joins the multicast group.

[0074] Optionally, determine the data transmission type according to the current transmission duration and the preset unicast transmission duration, including:

[0075] If the current transmission duration is less than the preset unicast transmission duration, determine that the data transmission type is unicast type.

[0076] In this embodiment, the unicast type can be understood as that the input node directly sends the data to the output node according to the port information of the output node carried in the request flow instruction, and the output node directly receives the data sent by the input node.

[0077] Specifically, when the current transmission duration is less than the preset unicast transmission duration, determine that the data transmission type is unicast type, that is, the input node directly sends the data to the output node according to the port information of the output node carried in the request flow instruction, and the output node directly receives the data sent by the input node.

[0078] If the current transmission duration is greater than or equal to the preset unicast transmission duration, determine that the data transmission type is multicast type.

[0079] In this embodiment, the multicast type can be understood as that the input node sends the data to the multicast corresponding to the multicast address, and the output nodes in the multicast group receive the data from the multicast group.

[0080] Specifically, when the current transmission duration is greater than or equal to the preset unicast transmission duration, determine that the data transmission type is multicast type, that is, the input node sends the data to the multicast corresponding to the multicast address, and the output nodes in the multicast group receive the data from the multicast group.

[0081] In the actual operation process, when transmitting data in unicast type, multiple output nodes may receive the data, and the input node transmits the data to multiple output nodes respectively. When the data transmission type is changed to multicast type, the input node only needs to transmit the data to the multicast group.

[0082] Optionally, if the current transmission duration is greater than or equal to the preset unicast transmission duration, determine that the data transmission type is multicast type, including:

[0083] If the current transmission duration is greater than or equal to the preset unicast transmission duration, receive the data in the multicast group corresponding to the multicast address.

[0084] Among them, the multicast group can be a multicast group corresponding to a multicast address generated by the input node according to the port information of the output node and the identification information of the input node.

[0085] In this embodiment, the data can be video data.

[0086] Specifically, when the current transmission duration is greater than or equal to the preset unicast transmission duration, it is determined that the data transmission type is the multicast type, that is, the input node sends the data to the multicast in the corresponding multicast address, and the output nodes in the multicast group receive the data in the multicast group corresponding to the multicast address.

[0087] In the actual operation process, after receiving the video data, the output node will decode the video data, and perform operations such as cropping, stretching or shrinking on the decoded video image according to the windowing instructions issued by the distributed broadcast control software, and then display it.

[0088] The embodiment of the present invention proposes an optimized data network transmission method for distributed unicast and multicast mixing, which combines the advantages of unicast and multicast and solves the disadvantages of both at the same time. When performing windowing operations in the distributed display control system, the input node first sends data to the output node through the unicast type. The output node can immediately receive the data and decode and display it, responding to this operation extremely quickly. At the same time, both the input node and the output node join the same multicast group. After the current transmission duration is greater than or equal to the preset unicast transmission duration, the input node changes to send data to the multicast group. At this time, the input node and the output node have joined the multicast group for some time, and the output node can immediately receive the data, which can greatly reduce the entire network bandwidth, reduce the pressure on the switch, and at the same time reduce the risk of packet loss, making the transmission and display more stable. The technical solution of the embodiment of the present invention can solve the problems of easy packet loss and video stuttering when using unicast to transmit data, as well as large bandwidth and poor experience when using multicast to transmit data, achieving the beneficial effects of making the large screen respond quickly, showing pictures quickly, improving the user experience, and at the same time reducing the network bandwidth and making the data transmission more stable.

This embodiment is applicable to the situation of determining the data transmission type. This method is applied to the input node. This method can be executed by a data transmission type determination device. The data transmission type determination device can be implemented in the form of hardware and / or software, and the data transmission type determination device can be integrated in any electronic device providing the function of determining the data transmission type. As Figure 2 shown, the method includes:

[0091] S201. Receive the request stream instruction sent by the output node.

[0092] Specifically, the input node receives the request stream instruction sent by the output node through the port bound by unicast.

[0093] S202. Obtain the current transmission duration corresponding to the request stream instruction.

[0094] Specifically, detect in real time the current transmission duration corresponding to the request stream instruction sent by the output node to the input node.

[0095] S203. Determine the data transmission type according to the current transmission duration and the preset unicast transmission duration.

[0096] Specifically, compare the current transmission duration with the preset unicast transmission duration in real time, and determine the data transmission type according to the comparison result of the current transmission duration and the preset unicast transmission duration.

[0097] The technical solution of the embodiment of the present invention, by receiving the request stream instruction sent by the output node, obtaining the current transmission duration corresponding to the request stream instruction, and determining the data transmission type according to the current transmission duration and the preset unicast transmission duration, solves the problems of easy packet loss and video stuttering when using unicast to transmit data, and large bandwidth and poor experience when using multicast to transmit data, and achieves the beneficial effects of making the large screen respond quickly, the image output fast, improving the user experience, and at the same time reducing the network bandwidth and making the data transmission more stable.

[0098] Optionally, the request stream instruction carries the port information of the output node.

[0099] After receiving the request stream instruction sent by the output node, it further includes:

[0100] Generate a multicast address according to the port information of the output node and the identification information of the input node.

[0101] Specifically, after the input node receives the request stream instruction sent by the output node, it obtains the port information of the output node carried in the request stream instruction, and calculates a unique multicast address through a certain algorithm according to the port information of the output node and the identification information of the input node, and creates a multicast group corresponding to the multicast address. Among them, the identification information of the input node can be the IP address of the input node.

[0102] Optionally, determining the data transmission type according to the current transmission duration and the preset unicast transmission duration includes:

[0103] If the current transmission duration is less than the preset unicast transmission duration, it is determined that the data transmission type is unicast type.

[0104] Specifically, when the current transmission duration is less than the preset unicast transmission duration, the data transmission type is determined to be the unicast type, that is, the input node directly sends the data to the output node according to the port information of the output node carried in the request flow instruction, and the output node directly receives the data sent by the input node.

[0105] If the current transmission duration is greater than or equal to the preset unicast transmission duration, the data transmission type is determined to be the multicast type.

[0106] Specifically, when the current transmission duration is greater than or equal to the preset unicast transmission duration, the data transmission type is determined to be the multicast type, that is, the input node sends the data to the multicast group corresponding to the multicast address, and the output nodes in the multicast group receive the data from the multicast group.

[0107] In the actual operation process, when transmitting data in the unicast type, multiple output nodes may receive the data, and the input node transmits the data to multiple output nodes respectively. When the data transmission type is changed to the multicast type, the input node only needs to transmit the data to the multicast group.

[0108] Optionally, if the current transmission duration is greater than or equal to the preset unicast transmission duration, determining that the data transmission type is the multicast type includes:

[0109] If the current transmission duration is greater than or equal to the preset unicast transmission duration, send the data to the multicast group corresponding to the multicast address.

[0110] Specifically, when the current transmission duration is greater than or equal to the preset unicast transmission duration, the data transmission type is determined to be the multicast type, that is, the input node sends the data to the multicast group corresponding to the multicast address, and the output nodes in the multicast group receive the data in the multicast group corresponding to the multicast address.

[0111] An embodiment of the present invention proposes a method for optimizing data network transmission in a distributed unicast and multicast hybrid manner, which combines the advantages of unicast and multicast and simultaneously solves the disadvantages of both. When performing a windowing operation in a distributed display and control system, the input node first sends data to the output node through the unicast type. The output node can immediately receive the data and decode and display it, responding extremely quickly to this operation. At the same time, both the input node and the output node join the same multicast group. After the current transmission duration is greater than or equal to the preset unicast transmission duration, the input node changes to send data to the multicast group. At this time, both the input node and the output node have joined the multicast group for some time, and the output node can immediately receive the data, which can greatly reduce the entire network bandwidth, reduce the pressure on the switch, and at the same time reduce the risk of packet loss, making both transmission and display more stable. The technical solution of the embodiment of the present invention can solve the problems of easy packet loss and video freezing when using unicast to transmit data, and large bandwidth and poor experience when using multicast to transmit data, achieving the beneficial effects of making the large screen respond quickly, showing pictures quickly, improving the user experience, and at the same time reducing the network bandwidth and making data transmission more stable.
