The master display device parameter value may be set to 1, and the slave device parameter values may be set to 2, 3, 4, and the like, and the present invention is not limited thereto. It should be noted that, the parameters of the startup page of each display device are different, and in a spliced screen system, if the master device is already set, the rest display devices are slave devices, that is, only one master device exists.
In setting the master and slave device parameter values, the setting may be performed by installing an application program in the display devices, for example, installing a server application in one display device and installing client applications in the remaining display devices. The master display device parameter value and the slave display device parameter value are set by different applications, respectively.
And step S13, setting a master display device and a slave display device according to the master display device parameter value and the slave device parameter value.
In this embodiment, in the process of powering on the display device, when the display device having the parameter value of the main display device is detected, the display device is regarded as the main display device; when a display device having a slave display device parameter value is detected, the display device is regarded as a slave display device.
In an embodiment, before the step S10, the method further includes:
step A101, setting the same network address and port for a plurality of display devices so that the plurality of display devices are in the same broadcast communication network.
In order to realize communication among a plurality of display devices, the plurality of display devices are provided with the same network address and port number, so that the plurality of display devices join the same network, thereby realizing mutual communication among the plurality of display devices, and in the same network, the instruction sent by the display devices can also be received, thereby realizing synchronous playing of the display devices.
In an embodiment, after the step S10, the method further includes:
step A102, acquiring state information of the main display equipment, and detecting whether the main display equipment is abnormal or not according to the state information;
after the main display device is set, the main display device controls the auxiliary display device to play the video, so that the auxiliary display device cannot be used because the main display device fails, and the main display device is required to be subjected to abnormality detection.
The state information includes a network connection condition, a display condition, a connection condition with the slave device, and the like, wherein the network connection condition is whether connection and connection stability are performed with the local area network, the display condition is whether normal display is performed, and the connection condition with the slave device is whether connection and connection stability are performed with all the slave devices. The network connection condition of the main display equipment is that the main display equipment is connected with the local area network, the display condition is that the display is normal, the connection condition of the main display equipment and the auxiliary display equipment is that the main display equipment is connected with the local area network, and the working state of the main display equipment can be judged to be normal when the main display equipment is stable. Otherwise, the main display device is considered to be abnormal.
Step a103, if the master display device is abnormal, selecting a slave display device from the slave display devices as a master display device, and executing the steps: and acquiring the state information of the main display equipment, and detecting whether the main display equipment is abnormal or not according to the state information until the main display equipment is selected.
In the present embodiment, when the main display device is in an abnormal state, in order to avoid occurrence of a play failure, it is necessary to reselect the main display device. Specifically, one slave display device may be randomly selected from the slave display devices as the master display device. The selection may be performed according to the order of the slave display device parameter values, for example, the slave display device parameter values are sequentially 2, 3, and 4.
In addition, when the abnormality of the main display device is detected, the state information of the main display device can be acquired again by controlling the main display device to wait for a preset period of time, and whether the main display device is replaced or not is determined according to the state information.
Step S20, receiving a control command sent by a user terminal, and controlling the master display device to send a synchronous play command to the slave display device and the master display device according to the control command, so that the slave display device and the master display device synchronously respond to the synchronous play command.
In this embodiment, the user terminal is a remote control device connected to the display device, and may be a remote controller or a mobile phone. The control command sent by the remote control device can be accepted by the main display device, wherein the control command comprises a parameter command, a play start command, a play stop command, a pause command, a play exit command and the like. After the master display device receives the control command, a synchronous play command is sent to the slave display device and the master display device, so that the master display device and the slave display device synchronously respond to the control command.
Specifically, in an embodiment, the step of controlling the master display device in step S20 to send a synchronous play command to the slave display device according to the control command, so that the slave display device and the master display device synchronously respond to the synchronous play command includes:
and step A21, controlling the master display device to send synchronous play instructions to all the slave display devices and the master display device at a preset frequency in a preset time according to the control command, so that the slave display device and the master display device respectively execute the operation command, and positioning a play time point to the target time point.
In this embodiment, the synchronous play command is in JSON format, and includes an operation command and a target time point, where the operation command includes a play start operation, a play stop operation, a pause operation, a play exit operation, and the like corresponding to the control command, and the target time point is a time point of a video stream corresponding to the operation command, for example, the operation command is a play start operation, and the time point of the video stream corresponding to the play start operation is 1s, or 2s, and the like.
Referring to fig. 4, after the master display device receives a control command sent by the user terminal, the master display device may send a synchronous play command corresponding to the control command to all slave display devices according to the control command, and simultaneously send the synchronous play command to the master display device itself, so that the slave display device and the master display device synchronously respond to the synchronous play command, thereby achieving the effect of synchronous video play. Wherein, the preset time is preferably 5 seconds, and the preset frequency may be 1 time/second. Taking the control command as a play start command as an example, the process of the master display device and the slave display device responding to the synchronous play command is as follows: after receiving the control command, the master display device sends a play-starting operation to all the slave display devices and the master display device in the 1 st second, and after receiving the play-starting operation, the slave display device and the master display device position the current play time point of the video stream to a position of 1 second; and at the time of 2 seconds, sending a play-up operation to all the slave display devices and the master display device, and positioning the current play time point of the video stream to the position of 2 seconds after the slave display devices and the master display devices receive the play-up operation. And after the preset time reaches 5 seconds, the response of the synchronous playing instruction is not carried out. In the synchronization process, the situation of the picture synchronization card frame occurs, so that the synchronous playing is only needed within the preset time of receiving the control command, the viewing experience of the user can be improved, and the situation of continuous card frame in the subsequent playing process is prevented. Of course, the person skilled in the art may also choose different preset times and preset frequencies, for example 10 seconds, and 2 times/second, the invention is not limited herein.
In addition, synchronous playing of the master display device and the slave display device is performed in a mode of a target time point, synchronous playing can also be performed in a mode of a video frame, specifically, the synchronous playing instruction comprises an operation command and a target frame, and the master display device sends the target frame to all the slave display devices and the master display device so that the master display device and the slave display device can be directly positioned to the position of the target frame for playing, and synchronous playing of the master display device and the slave display device is achieved. In this embodiment, the synchronization process can be more accurate by the positioning manner of the video frame.
In an embodiment, after the step S20, the method further includes:
step A30, acquiring the playing time points of the master display device and the slave display device in real time, and judging whether the playing time points of the master display device are consistent with the playing time points of the slave display device or not;
step A30, if not, generating a synchronous playing instruction according to the playing time point of the main display device, and executing the steps: and controlling the master display device to send synchronous playing instructions to all the slave display devices and the master display device at preset frequency in preset time according to the control command.
In this embodiment, in order to prevent occurrence of a situation in which the play progress of the master display device and the slave display device are inconsistent during the video play process, it is therefore determined whether the videos are always kept in synchronization by monitoring the play time points of the master display device and the slave display device in real time. And under the condition that the videos are not synchronized, the slave display device and the master display device are synchronously played again according to the playing time point of the master display device. The video synchronization can be automatically corrected, and the synchronous playing effect is ensured.
