Next, referring to fig. 5, fig. 5 is a step of operating the display device when the display device provided in the embodiment of the present application is synchronized with the second display device, specifically as follows:

step S501, determining a first time consumption with the second display device, the first time consumption being used to characterize a time required for communication between the display device and the second display device;

wherein the second display device is a further display device capable of communicating with the display device, and "second" is to distinguish from the display device, the components (display and controller) of the second display device being another component than the display and controller of the display device. The second display device may include a plurality of second display devices, and the method for synchronizing the plurality of second display devices with the display device is the same, which is not described in detail herein, but only an example of any one of the second display devices is described.

The first time consuming refers to a communication time consuming between the display device and the second display device. When the display device needs to synchronously play the same target video with the second display device, firstly, information interaction is performed with the second display device, so that the playing progress of the display device and the playing progress of the second display device are determined, and when the display device and the second display device can synchronously play the target video in combination with other data, the playing progress of the target video (hereinafter referred to as a first target playing progress) is determined. Because the display equipment and the second display equipment have communication time consumption in the process of information interaction, when the display equipment determines the first target playing progress, the communication time consumption between the display equipment and the second display equipment needs to be considered, so that the display equipment can be assisted to determine the more accurate first target playing progress, the aim of synchronously playing target videos by a plurality of display equipment is fulfilled, and the watching experience of a user is improved.

In one embodiment, as shown in fig. 6, fig. 6 is an alternative method embodiment of how a display device provided in the embodiment of the present application determines a first time consumption, where the method embodiment includes the following steps:

step S601, sending second information carrying the first playing progress to a second display device, and recording a first moment of sending the second information;

the first playing progress may be a time period (herein referred to as a first playing time period) that the display device has played the target video when it is required to determine a first time consumption (i.e., a first target time) with the second display device. After the display device obtains the first playing progress of the current playing target video, the first playing progress may be encapsulated in second information, and then the second information is sent to the second display device through the network. The display device needs to record the time at which the second information is transmitted to the second display device (hereinafter referred to as the first time) in order to obtain the first time. It should be noted that, the first target time and the first time are determined according to the time displayed on the progress bar of the target video when the display device plays the target video, and because each display device starts playing the target video at the same time, determining the time consumption according to the playing time of the target video can avoid inaccurate time consumption due to the difference of the device clocks of each display device. Further provide preconditions for determining a more accurate first target playing progress.

It should be noted here that the display device is in a state of continuously playing the target video before determining the first time consuming with the second display device. And the display device may play the target video at a preset play speed.

For example, the display device obtains the current played target video for 1 minute, then generates second information, sends the second information to the second display device, and records that the first time is 00:11.

Step S602, receiving third information sent by the second display device based on the second information, and recording a second moment of receiving the third information, wherein the third information characterizes the second information received by the second display device;

after the display device sends the second information to the second display device, the second display device needs to feed back to the display device aiming at the second information sent by the display device, which is equivalent to informing the display device that the second information is received. Therefore, the second display device generates the third information and transmits the third information to the display device. The display device needs to record the moment when the third information is received (hereinafter referred to as the second moment) to determine the first time consumption in combination with the first moment. It should be noted that, the second time is determined according to the time displayed on the progress bar when the target video is played, for the reasons described above, which are not described herein.

The display device receives the third information sent by the second display device, and the distance from the moment when the third information is received is 00:13.

In step S603, a first time consumption is determined according to the difference and the ratio of the difference to the first constant, where the difference is the difference between the second time and the first time.

Wherein the display device obtains the time of sending and receiving information based on one information interaction with the second display device, and the first constant is 2 because the interaction between the display device and the second display device is a process of going back and forth. The display device may be configured to first make a difference between the second time and the first time and then divide the difference by 2 to obtain the first time consumption.

Illustratively, the first time is 00:11 and the second time is 00:13, then the first time is 00:02 +.2=00:01. I.e. 1 second.

Step S502, determining a second time consumption of the second display device, wherein the second time consumption is used for representing time required by the second display device to search and play the target video to a first playing progress, and the first playing progress is a first playing duration of the display device for playing the target video at a first target moment;

the second time consuming is the time required by the second display device to search the video frame corresponding to the first playing progress of the target video indicated by the display device according to the third information sent by the display device and play the video frame. It should be noted that, the second display device may also play the target video simultaneously with the display device, and the second display device is also in the process of continuously playing the target video at this time. The first playing progress is a time period (referred to herein as a first playing time period) that the display device needs to determine a first time consumption (i.e., at a first target time) with the second display device. The first target time is determined according to the time displayed by a progress bar on a target interface of the target video played by the display device.

In one embodiment, as shown in fig. 7, fig. 7 is an alternative method embodiment of determining a second time consumption by the display device according to an exemplary embodiment of the present application, where the method embodiment includes the following steps:

step S701, after receiving the third information, receiving fourth information sent by the second display device, and recording a third time when the fourth information is received, where the fourth information is used to instruct the second display device to search and play the target video to the first playing progress;

after receiving the second information sent by the display device, the second display device searches video frames corresponding to the first playing progress according to the first playing progress indicated in the second information, and plays the video frames after searching the video frames corresponding to the first playing progress. And the second display equipment generates fourth information after searching and playing the video frames corresponding to the first playing progress, and sends the fourth information to the display equipment. That is, the second display device informs the display device itself that the target video has been played to the video frame corresponding to the first playing progress through the fourth information.

In order to facilitate the subsequent calculation of the second time consumption, the display device needs to record the third time when the fourth information is received after receiving the fourth information sent by the second display device. For example, the third time is, for example, 00:14, where it should be noted that the third time is also determined according to the time of displaying the playing progress bar on the target video playing interface when the fourth information is received during the process of playing the target video by the display device.

In step S702, the second time consumption is determined according to the difference between the first time consumption, the second time and the third time.

The progress of simultaneous playing with the display device can be accurately determined for the subsequent display device. The display device may calculate a difference between the third time and the second time when the first time, the second time, and the third time are obtained, and then make the difference with the first time to obtain the second time.

For example, the first time is 1 millisecond, the second time is 12:02, and the third time is 12:04. Second time=12:04-12:02-00:01=00:01, also 1 millisecond.

Step S503, determining a first target playing progress according to a second playing progress, a first time consumption and a second time consumption, wherein the second playing progress is a second playing duration of the target video played by the display device at a second target time, and the first target time is earlier or later than the second target time;

in the process of determining the first time consuming, the second time consuming and the interaction with the second display device, the target video is always in a playing state on the display device, so as to determine a more accurate first target playing progress. The display device may determine, according to the display device, a second playing duration (i.e., a second playing progress) of the target video that has been played after the first time consuming and the second time consuming, and determine, in combination with the first time consuming and the second time consuming, a progress of the target video that can be played by the display device in synchronization with the second display device. Here, the second target time is the time when the display devices determined according to the second playing progress, the first time consumption and the second time consumption need to synchronously play the display on the target video progress bar. If the target video is played in positive sequence, the first target time is earlier than the second target time; if the target video is played in reverse order, the first target time is later than the second target time.

In one embodiment, the display device may determine the first target playback progress based on a sum of the second playback progress, the first time consuming, and the third time consuming.

For example, if the second playing progress is 2 minutes, the first time is 1 millisecond, and the second time is 1 millisecond, then the first target playing progress is 2+0.1+0.1=2.2 minutes.

Step S504, the first information carrying the first target playing progress is sent to the second display device, so that the display device and the second display device play the target video to the first target playing progress at the same time.

After the display device determines that the first target playing progress is obtained according to the method, the first target playing progress may be packaged into the first information and sent to the second display device. After receiving the first information, the second display device can search the video frame corresponding to the first target playing progress and play the video frame, and because the communication time consumption between the first and second display devices and the time consumption of the second display device for searching the video frame are considered when the display device determines the first target playing progress, the purpose that the second display device plays the target video to the first target playing progress just when the display device plays the target video to the first target playing progress can be achieved, and therefore the purpose that a plurality of display devices synchronously play the target video is achieved. And the experience of the user when watching the target video through a plurality of display devices is improved.

In another embodiment, as shown in fig. 8, fig. 8 is an alternative method embodiment of performing a synchronization operation again after performing synchronization once between a display device and a second display device according to the embodiment of the present application, where the method embodiment includes the following steps:

step S801, after a preset time period for transmitting first information carrying a first target playing progress to a second display device, determining a third time consumption with the second display device, where the third time consumption is used to characterize a time required for communication between the first display device and the second display device at a preset first time;

firstly, it should be noted that in the process of playing the target video, the display device and the second display device may perform synchronization only once, may perform synchronization multiple times, or may perform synchronization from time to time, which is not limited in this application.

Then, the display device may perform the synchronization operation with the second display device again by the above method after the first information is transmitted to the second display device for a preset period of time after the completion of the synchronization once. The preset time period may be determined according to information of performance of the display device, performance of the second display device, history synchronization parameters, and the like. The preset time period is, for example, 2 minutes, 3 minutes, 10 minutes, etc., which is not limited in this application.

In the same manner as the above synchronization, the display device may determine the time required for communication with the second display device at the preset first time (i.e., the third time), and the third time may be the same time as the first time or may be a different time. The third time-consuming determining method is the same as the first time-consuming determining method, and is not described herein. It should be noted that, the preset time period and the preset first time are both determined according to the time when the display device displays the target video on the progress bar on the display interface.

Step S802, determining a fourth time consumption of the second display device, wherein the fourth time consumption is used for representing time required by the second display device to search and play the target video to a third playing progress, and the third playing progress is a third playing duration of the display device for playing the target video at a preset first time;

the fourth time consumption has the same meaning as the second time consumption, and is used for determining the time required by the second display device to search and play the target video to the play progress designated by the display device. The fourth time consumption may be the same as the second time consumption or may be different from the second time consumption. The fourth time consuming determining method is the same as the second time consuming determining method, which is not limited in this application.

Step S803, determining a second target playing progress according to a fourth playing progress, a third consuming time and a fourth consuming time, wherein the fourth playing progress is a fourth playing duration of the target video played by the display device at a preset second moment, and the preset first moment is earlier or later than the preset second moment;

after determining the third time consumption and the fourth time consumption, the display device may determine the second target playing progress according to the sum of the progress of playing the target video (i.e., the fourth playing progress) and the third time consumption and the fourth time consumption when determining the third time consumption and the fourth time consumption. The method for determining the second target playing progress is the same as the method for determining the first target playing progress, and will not be described in detail herein.

Step S804, the fifth information carrying the second target playing progress is sent to the second display device, so that the display device and the second display device play the target video to the second target playing progress at the same time.

The display device may encapsulate the second target playing progress to the fifth information after determining the second target playing progress, and send the second target playing progress to the second display device through the network, so that when the display device plays the target video to the second target playing progress, the second display device plays the target video to the second target playing progress just too. The display device and the second display device are operated synchronously again.
