The master and slave display devices carry two interactive protocols, message queue telemetry transport (Message Queuing Telemetry Transport, MQTT) and user datagram protocol (User Datagram Protocol, UDP). The MQTT protocol is responsible for receiving and sending synchronous information, and the UDP protocol is responsible for broadcasting notification of the online and offline of the host. The master display device and the slave display device establish connection with an MQTT server (message queue telemetry transport protocol server) through an MQTT client module, subscribe to the same theme, and enable the master player and the slave player to establish association so as to prepare for receiving and transmitting subsequent synchronous information.
Fig. 8 is an application software architecture diagram. In some embodiments, as shown in fig. 8, the playing of the video file still uses the playing module of the system, and the playing control function is implemented through the basic playing control interface. Meanwhile, the application layer introduces two communication protocols of UDP and MQTT, is responsible for communication interaction among a plurality of terminals, and finally completes the synchronous playing function of the plurality of terminals. The method is not related to the change of the system layer player, and is realized only in the application layer, so that the scheme is application-level and has the advantages of light weight, good compatibility, easiness in maintenance and the like.
In some embodiments, as shown in FIG. 9, after a display device is set as a host, the host may initiate an MQTT server and subscribe after coming online. After subscribing, broadcasting the IP address of the anchor in the network through UDP broadcast messages, after receiving the on-line messages of the anchor, the anchor unsubscribes if other anchors are subscribed, and re-subscribes to the new on-line anchor, namely, the on-line anchor later kicks off the on-line anchor earlier, so that only one anchor in the network is maintained.
In some embodiments, as shown in fig. 10, a display device is configured to query the host in the network for information via UPD broadcast messages after the slave is on-line, the host receives the UDP broadcast query and feeds back, and the slave receives the feedback and subscribes to the MQTT.
In some embodiments, the steps of synchronously playing the master display device and the slave display device are as follows:
the main display device receives a control instruction of a playing film source input by a user operating the control device through a user interface.
For example, the user interface may receive a control instruction from a user to input a play source by pressing a directional key on the control device to select a play control and pressing a confirm key on the control device.
And responding to the control instruction of the playing film source, playing by the master display device, and pushing the playing message to the slave display device through the MQTT protocol.
After receiving the anchor play-starting message from the display equipment, playing the film source and sending a playing progress inquiry message to the master display equipment, wherein the playing progress inquiry message is used for inquiring the playing progress of the master display equipment, and the playing progress inquiry message also comprises the playing progress of the slave display equipment;
after receiving the playing progress of the slave display device, the master display device compares the difference value of the playing progress of the master display device and the playing progress of the slave display device, namely, calculates a first playing progress difference value according to the playing progress of the master display device and the playing progress of the slave display device;
if the absolute value of the first playing progress difference value is larger than the jump critical value, a first synchronous message is sent to the slave display equipment, and the first synchronous message comprises the playing progress of the master display equipment;
the slave display device jumps the playing progress of the slave display device to the playing progress of the master display device;
in some embodiments, the slave display device invokes seek to synchronize with the master display device.
If the first playing progress difference value is larger than 0 and is between the skip critical value and the pause critical value, the main display device pauses the first playing progress difference value and then continues playing; wherein the jump threshold is greater than the pause threshold.
In some embodiments, a first play progress difference value greater than 0 indicates that the master display device has a play progress greater than the slave display device. The main display device calls the pause interface, and continues playing after pausing the first playing progress difference time unit.
If the first playing progress difference value is smaller than 0 and the absolute value is between the skip critical value and the pause critical value, the main display device continues playing after pausing the first playing progress difference value, and the method can adjust the playing progress of the auxiliary display device by pausing later without any processing. Wherein, the first play progress difference value is smaller than 0, which indicates that the play progress of the master display device is slower than that of the slave display device.
If the absolute value of the first playing progress difference value is smaller than the jump critical value, no processing can be performed.
The absolute value of the first playing progress difference value is smaller than the pause critical value and does not affect the error area of the subjective experience synchronization effect, so that no processing is performed.
In some embodiments, the first play progress difference n1=master-slave, wherein master: representing the current playing progress of the main player, and obtaining unit milliseconds; slave: representing the current playing progress of the slave player in milliseconds; seek_value: a threshold value for executing seek operations in milliseconds; pause_value: the threshold for the pause operation is performed in milliseconds.
If Math.abs (N1) > seek_value, sending a first synchronization message to the slave display device, wherein the first synchronization message comprises the playing progress of the master display device; the slave display device jumps the playing progress of the slave display device to the playing progress of the master display device;
if N1 is more than 0 and the pause_value is less than or equal to N1 and less than or equal to seek_value, the main display device continues playing after pausing for N1 time units;
if N1 is less than 0 and pause_value is less than Math.abs (N1) < seek_value, no processing is performed;
if Math.abs (N1) < pause_value, no processing is done.
In some embodiments, it is possible to implement the step of playing the master display device and the slave display device synchronously, but invoking seek (jump interface) may still cause the master display device and the slave display device to have errors in playing progress, so the slave display device may send a playing progress query message to the master display device multiple times, so that the master display device repeatedly performs the step of performing the difference between the playing progress of the master display device and the playing progress of the slave display device, and causes the master display device to play synchronously with the slave display device. The number of times of the repeated execution may be set according to specific needs.
In some embodiments, the step of performing the difference between the playing progress of the master display device and the playing progress of the slave display devices is performed multiple times, so that the playing progress of the master display device is as small as possible or equal to the playing progress of all the slave display devices, and thus synchronous playing of all the display devices is achieved by adjusting the playing progress of the slave display devices. In this case, the step of synchronously playing the master display device and the slave display device further includes:
The master display device sends a second synchronous message to the slave display device through the MQTT protocol, wherein the second synchronous message comprises the playing progress of the master display device;
after the slave display device receives the playing progress of the master display device, comparing the difference value of the playing progress of the slave display device and the playing progress of the master display device, namely calculating a second playing progress difference value according to the playing progress of the slave display device and the playing progress of the master display device;
if the absolute value of the second playing progress difference value is larger than the jump critical value, jumping the playing progress of the slave display device to the playing progress of the master display device;
in some embodiments, the slave display device invokes seek to synchronize with the master display device.
If the second playing progress difference value is greater than 0 and is between the skip critical value and the pause critical value, the playing is continued after the second playing progress difference value is paused from the display device.
In some embodiments, a second play progress difference value greater than 0 indicates that the play progress of the slave display device is greater than the play progress of the master display device. And calling the pause from the display device, and stopping playing after the time unit of the difference value of the playing progress is paused.
If the absolute value of the second playing progress difference value is smaller than the pause critical value, no processing is carried out;
The absolute value of the second playing progress difference value is smaller than the pause critical value and does not affect the error area of the subjective experience synchronization effect, so that no processing is performed.
In some embodiments, the second play progress difference n2=slave-master, wherein master: representing the current playing progress of the main player, and obtaining unit milliseconds; slave: representing the current playing progress of the slave player in milliseconds; seek_value: a threshold value for executing seek operations in milliseconds; pause_value: the threshold for the pause operation is performed in milliseconds.
If Math.abs (N2) > seek_value, jumping the playing progress of the slave display device to the playing progress of the master display device;
if N2 is more than 0 and the pause_value is less than or equal to N2 and less than or equal to seek_value, continuing playing after pausing N2 time units from the display device;
if Math.abs (N2) < pause_value, no processing is done.
In some embodiments, it is possible to implement the master display device and the slave display device to play synchronously through the above steps, but it is still possible to call seek (jump interface) to cause an error between the play progress of the master display device and the slave display device, so the master display device may send the second synchronization message multiple times to cause the slave display device to repeatedly perform the step of the difference between the play progress of the master display device and the play progress of the slave display device, and to cause the master display device and the slave display device to play synchronously. The number of times of the repeated execution may be set according to specific needs.
The embodiment of the application realizes the customization of the synchronous interaction strategy and the optimization of reducing the synchronous play difference value, not only realizes progress catch-up by using the jump interface of the player, but also timely introduces a pause mechanism to make pause wait when meeting the conditions, thereby realizing synchronous play of a plurality of display devices in the same group and unifying pictures.

step S1101: responding to a control instruction of a playing film source, and playing by the main display equipment;
step S1102: the master display device pushes the play-up message to the slave display device;
step S1103: play from the display device;
step S1104: the slave display device sends a playing progress inquiry message to the master display device;
step S1105: calculating a first play progress difference value of the play progress of the master display device and the play progress of the slave display device;
if the absolute value of the first playing progress difference is greater than the jump threshold, step S1106 is executed.
