Based on the above control system for media display, the embodiment of the present application provides a control method for media display. Referring to fig. 3, fig. 3 is a signaling diagram of a control method for media display according to an embodiment of the present disclosure. The method is applied to a control system of a media display, as shown in FIG. 2, and comprises the following steps.
Step 31, the client acquires a first media code stream in a first coding format from the image acquisition device.
When the media code stream collected by the image collecting equipment needs to be displayed, the client side obtains a first media code stream in a first coding format from the image collecting equipment. In the embodiment of the application, the client and the image acquisition device can adopt a standard protocol to transmit media code streams, and the media code streams comprise video code streams and/or audio code streams. The first encoding format is an encoding format under a standard protocol. The standard Protocol may include, but is not limited to, RTMP (Real Time Messaging Protocol), RTSP (Real Time Streaming Protocol), and the like.
In one example, the image capture device may send the media codestream to the client in real-time. This can improve the efficiency of the client to obtain the media stream.
In another example, a user may input a code stream acquisition instruction for an image acquisition device to a client. And after receiving the code stream acquisition instruction, the client sends the stream acquisition instruction to the media acquisition equipment. And the image acquisition equipment sends a first media code stream in a first coding format to the client according to the stream fetching instruction.
Step 32, the client adjusts the first media code stream into a second media code stream with a second coding format, wherein the second coding format is a coding format of the media code stream negotiated by the client and the control device in advance.
In the embodiment of the application, the client and the control device negotiate in advance for a second encoding format of the media code stream. The client adjusts the first media code stream into a second media code stream in a second coding format, specifically, the first media code stream is decoded according to the first coding format to obtain media data, and then the media data is encoded according to the second coding format to obtain the second media code stream.
The second encoding format can be set according to the actual requirement of the user. The second encoding format may include, but is not limited to, an AVI (Audio Video Interleaved) format and an RMVB (real media Variable bit rate) format, an MPEG (Moving Pictures Experts Group) -2 format, a VC-1 format, an h.264 format, and the like.
And step 33, the client sends the second media code stream to the control equipment.
And the client transmits the second media code stream to the control equipment after acquiring the second media code stream.
And step 34, the control device receives the second media code stream, and decodes the second media code stream according to the second coding format to obtain media data.
If the media code stream includes a video code stream and an audio code stream, the media data includes video data and audio data.
And the control equipment receives the second media code stream, and decodes the second media code stream according to a second coding format negotiated with the client in advance to obtain media data.
Step 35, the control device sends the media data to the display wall.
In an alternative embodiment, the display wall includes a plurality of display areas, one display area corresponding to one LCD or LED display unit. At this time, the control device includes a plurality of media outlets, which correspond to the display areas one to one.
Before receiving the second media code stream, the control device receives a configuration instruction which is issued by the client and aims at the image acquisition device, wherein the configuration instruction comprises the size of an image display window of the media code stream acquired by the image acquisition device and a media output port required for transmitting the media code stream acquired by the image acquisition device.
After the control device obtains the second media code stream, the control device segments the second media code stream according to the configuration instruction including the size of the image display window and the media output port to obtain a plurality of sub-media code streams, and determines the media output port corresponding to each sub-media code stream. And the control equipment caches each sub-media code stream to the corresponding cache region, reads the sub-media code stream from the cache region, and transmits the sub-media code stream to the display wall through the corresponding media output port.
Step 36, the display wall displays the media data.
In an alternative embodiment, the display wall includes a plurality of display areas, one display area corresponding to one LCD or LED display unit. At this time, the control device includes a plurality of media outlets, which correspond to the display areas one to one. And the display wall receives the sub-media code stream sent by the control equipment through a media output port and displays the sub-media code stream through the corresponding display area.
In the technical scheme provided by the embodiment of the application, the client acquires the media code stream from the image acquisition device and pushes the code stream to the control device, that is, the client pushes the media code stream to the control device in an active stream pushing mode. The media display control can be realized only by the interaction between the client and the image acquisition equipment, and the interaction between the image acquisition equipment on the monitoring site and the remote control equipment is not needed. The client is installed on the computer, the computer can easily realize division of multiple network domains, and the image acquisition equipment working in each network segment is compatible, so that by adopting the technical scheme provided by the embodiment of the application, the limitation on the network topology of the monitoring site is reduced, and the deployment of the network topology of the monitoring site is more flexible.
In addition, in the technical scheme provided by the embodiment of the application, the client and the control device negotiate in advance about the coding format of the media code stream, and the client can self-determine the protocol for transmitting the media code stream, control the display of media, improve the flexibility of media code stream transmission, and facilitate the management and maintenance of users. In the embodiment of the application, the coding format of the media code stream processed by the control equipment is not limited, the use scene of the control equipment is expanded, and the competitiveness of the product is improved.
Thirdly, in the technical scheme provided by the embodiment of the application, the client processes the media code stream collected by the image collection device first, and sends the processed code stream to the control device. The client is installed on the computer, and the encoding formats of the media code streams which can be processed by the client are more than those of the control equipment, which means that the control equipment can process more media code streams with the encoding formats, so that the compatibility of the control equipment to the image acquisition equipment is improved, and the application scene of the control equipment is expanded.
Based on the embodiment of the control method for media display shown in fig. 3, the embodiment of the present application further provides a control method for media display. Referring to fig. 4, fig. 4 is a signaling diagram of a control method for media display according to an embodiment of the present disclosure. The method is applied to a control system of a media display, and as shown in fig. 2, the method can comprise the following steps.
And step 41, the client sends an active plug flow instruction to the control equipment.
In the embodiment of the application, the active stream pushing instruction is used for indicating the client to send the media code stream to the control device. Before the client acquires the media code stream from the image acquisition equipment, an active stream pushing instruction is generated and sent to the control equipment.
In an alternative embodiment, the client has a display screen that includes an image display window and a list of image capture devices, as shown in fig. 5. The client can also be used for receiving dragging operation aiming at the identification of the image acquisition equipment in the image acquisition equipment list; and when the identifier of the image acquisition equipment is dragged to the image display window, generating an active plug flow instruction.
For example, as shown in fig. 5, the image capturing device list includes an identifier a of the image capturing device and an identifier b of the image capturing device. When a user drags the identifier a of the image acquisition equipment or the identifier b of the image acquisition equipment to the image display window, an active stream pushing instruction is generated and sent to the control equipment.
In the embodiment of the present application, the active stream pushing instruction may not include encoding information that instructs the client to transmit the media stream in the second encoding format. That is, the client and the control device negotiate the encoding format of the media code stream in advance, such as the second encoding format, and generate a decoding function module corresponding to the client, where the decoding function module is a function module for decoding the media code stream in the second encoding format; and then, the client sends an active stream pushing instruction to the control equipment.
The active stream push instruction may include encoding information instructing the client to transmit the media stream in the second encoding format. That is, the client may negotiate with the control device about a second encoding format for transmitting the media code stream while instructing the client to send the media code stream to the control device based on the active stream pushing instruction, and generate the decoding function module corresponding to the client.

Before the client acquires the media code stream from the image acquisition equipment, the default coding format is used as a second coding format, and then an active stream pushing instruction is generated, wherein the active stream pushing instruction carries coding information for instructing the client to transmit the media code stream in the second coding format.
In another example, before the client acquires the media code stream from the image acquisition device, the client outputs a prompt window to prompt the user to input the encoding format of the media code stream transmitted between the client and the control device. The client takes the coding format input by the user as a second coding format, and further generates an active stream pushing instruction, wherein the active stream pushing instruction carries coding information indicating that the client transmits the media code stream in the second coding format.
In yet another example, a default encoding format is preset in the client. Before the client acquires the media code stream from the image acquisition equipment, the client outputs a prompt window to prompt a user to input a coding format of the media code stream transmitted between the client and the control equipment. And if the coding format input by the user is not received after a period of time, the client uses the default coding format as a second coding format to further generate an active stream pushing instruction, and the active stream pushing instruction carries coding information indicating that the client transmits the media code stream in the second coding format. If the coding format input by the user is received within a period of time, the client uses the coding format input by the user as a second coding format, and further generates an active stream pushing instruction, wherein the active stream pushing instruction carries coding information indicating that the client transmits the media code stream in the second coding format.
In the embodiment of the present application, the manner of generating the active plug flow instruction is not limited.
And 42, the control device receives the active stream pushing instruction, and starts a decoding function module corresponding to the client according to the active stream pushing instruction, wherein the decoding function module is a function module for decoding the media code stream in the second coding format.
And the control equipment receives the active stream pushing instruction, determines a decoding functional module corresponding to the client according to the active stream pushing instruction, and starts the decoding functional module. Subsequently, after the control device receives the media code stream sent by the client, the control device decodes the media code stream in the second coding format by using the decoding function module to obtain the media data.
In the embodiment of the application, the user can transmit the media data by using the self-defined protocol or streaming media without concerning too many operation flows and details of the control equipment, and the method is friendly to the secondary development of the third-party client.
And 43, after the control device starts the decoding function module, feeding back a first success response instruction aiming at the active stream pushing instruction to the client.
In the embodiment of the application, after the decoding function module is started, the control device feeds back a first successful response instruction for the active stream pushing instruction to the client. The phenomena of loss, fast forward, unsmooth and blockage of pictures displayed on a display wall caused by the fact that the control equipment receives media data sent by the client under the condition that the decoding function module is not started are avoided.
And step 44, the client acquires the first media code stream in the first coding format from the image acquisition equipment.
And step 45, the client adjusts the first media code stream into a second media code stream with a second coding format, wherein the second coding format is a coding format of the media code stream negotiated by the client and the control equipment in advance.
And step 46, the client sends the second media code stream to the control equipment.
