Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in further detail below.
Example one
Referring to fig. 1, a flowchart of steps of a playing method according to a first embodiment of the present invention is shown, where the method is applied to a playing system, where the playing system includes a server, a first terminal and at least one second terminal, and the first terminal and the second terminal are in the same local area network, and the method includes the following steps:
step 101: and the first terminal receives the playing content and the playing control information sent by the server.
Referring to fig. 2, a schematic diagram of a playing system according to a first embodiment of the present invention is shown, where the playing system may include a server 10, a first terminal 20, and at least one second terminal 30, it is to be understood that the number of the second terminals 30 is not particularly limited in the embodiment of the present invention, and fig. 2 only exemplarily shows 4 second terminals 30. The first terminal 20 and the second terminal 30 are in the same local area network W, and in practical applications, the server 10 and the first terminal 20 and the second terminal 30 may be in one local area network or not, which is not specifically limited in this embodiment of the present invention.
If the server 10 is in a local area network with the first terminal 20 and the second terminal 30, the server 10 may communicate with the first terminal 20 and the second terminal 30 through the local area network. If the server 10 and the first and second terminals 20 and 30 are not in a local area network, the server 10 may communicate with the first and second terminals 20 and 30 in the local area network through a network, such as a wireless network.
In a local area network, a plurality of terminals needing synchronous playing can be called a playing terminal group. Of course, a plurality of sets of terminals may be included in a local area network. The first terminal is a main control playing terminal in a playing terminal group, and each second terminal in the same group with the first terminal can realize synchronous playing with the first terminal together according to the command of the first terminal.
When a user needs to realize synchronous playing of a playing terminal group, the user can issue a playing command through a server on the server, and the server can send playing contents and playing control information to each terminal in the playing terminal group, so that the first terminal and each second terminal can receive the playing contents and the playing control information sent by the server. The playing content may include at least one video, image, and the like to be played. The playing control information, i.e. the playing plan for the playing content, may include a playing time length, a starting node and/or an ending node (e.g. a starting/ending time point or a starting/ending frame position of the video) of the playing content, a cycle number of the playing content, and the like.
Step 102: and the second terminal receives the playing content and the playing control information sent by the server.
In the embodiment of the present invention, the server may send the playing content and the playing control information to both the first terminal and the second terminal, and accordingly, the second terminal may receive the playing content and the playing control information sent by the server.
Step 103: the first terminal generates a first synchronization command, and the first synchronization command comprises first target frame information in the playing content.
In the embodiment of the present invention, after receiving the playing content and the playing control information, the first terminal may generate the first synchronization command, where the first synchronization command may include first target frame information in the playing content, and the first target frame information is a synchronization node of the playing content. The first terminal and the second terminal can realize the playing synchronization only by starting the playing from the same node for playing the content synchronously, and the node is also the synchronous node for playing the content. In practical applications, the synchronization node may be a certain frame position of the playing content or a certain time point of the playing content, which is not specifically limited in this embodiment of the present invention.
The first synchronization command may further comprise an identification of the synchronization command and a priority of the sender of the synchronization command, i.e. the priority of the first terminal.
Step 104: the first terminal sends the first synchronization command to each second terminal, so that the second terminals start to play the pre-received playing content according to the pre-received playing control information from the first target frame information when receiving the first synchronization command.
In this embodiment of the present invention, after the first terminal generates the first synchronization command, the first synchronization command may be sent to each second terminal in the same group of playing terminals, so that when the second terminal receives the first synchronization command, the second terminal starts to play the pre-received playing content according to the pre-received playing control information from the first target frame information.
Step 105: the second terminal receives the first synchronization command sent by the first terminal.
In the embodiment of the present invention, each second terminal belonging to the same group of the playing terminals as the first terminal may receive the first synchronization command sent by the first terminal.
Step 106: and the second terminal plays the playing content from the first target frame information according to the playing control information.
In this embodiment of the present invention, the second terminal may read the first target frame information from the first synchronization command, and may then play the playing content according to the playing control information, starting from the first target frame information.
In the embodiment of the present invention, a first terminal in a local area network may receive a play content and play control information sent by a server, and then generate a first synchronization command, where the first synchronization command includes first target frame information in the play content. Then, the first terminal may send the first synchronization command to each second terminal in the local area network, and the second terminal may play the pre-received play content according to the pre-received play control information, starting from the first target frame information, when receiving the first synchronization command. In the embodiment of the present invention, the first synchronization command for implementing synchronous playing may be sent by the first terminal to each second terminal in the same lan, and then both the first terminal and the second terminal may start playing the content from the first target frame information in the first synchronization command, thereby implementing synchronous playing. Because the synchronous operation is finished by the first terminal and the second terminal in the same local area network without being executed by a server, the synchronous operation in the local area network does not depend on the network condition between the server and the terminals, thereby improving the accuracy of the synchronous playing of a plurality of terminals.
Example two
Referring to fig. 3, a flowchart illustrating steps of another playing method according to a first embodiment of the present invention is shown, where the method includes the following steps:
step 201: the server sends the first playing configuration information to the first terminal and sends each second playing configuration information to the corresponding second terminal.
In the embodiment of the present invention, in a local area network, a plurality of terminals that need to play synchronously may be referred to as a group of playing terminals. The terminals in each of the groups of the terminals in the lan can be registered in the server. After the terminal completes the registration in the server, the server may obtain a Media Access Control (MAC) address of each terminal. The user can group the terminals registered in the server through the server, that is, the terminals registered in the server are divided into at least one play terminal group.
After grouping is completed, the server may transmit the play configuration information to each terminal in the group of the play terminals. In a specific implementation manner, the playing configuration information may include a playing configuration identifier, a priority of the terminal as a playing main control terminal, MAC addresses of other terminals in the playing terminal group, and a unit time T of waiting for a synchronization command of the main control terminal when executing a playing task. The time for waiting for the synchronization command of the main control terminal when one terminal executes the play task can be positive integer times of T. Alternatively, T may be greater than or equal to 50 milliseconds and less than or equal to 100 milliseconds.
If there are n terminals, the first terminal is the master play control terminal with the highest priority, which may be marked as P0, all the second terminals have priorities lower than that of the first terminal, the n-1 second terminals have priorities of P1, P2, … … and Pn-1, respectively, and the lowest priority may be marked as Pn-1.
Step 202: the server sends the playing content and the playing control information to the first terminal and the second terminal.
In the embodiment of the present invention, a user may send a play content and a play command to a play terminal group through a server, where the play command may include a play command identifier of the server, play control information, a start time point and a stop time point of play.
Step 203: and the first terminal receives the playing content and the playing control information sent by the server.
Step 204: and the second terminal receives the playing content and the playing control information sent by the server.
Step 205: the first terminal generates a first synchronization command, and the first synchronization command comprises first target frame information in the playing content.
In the embodiment of the present invention, the step may be specifically implemented by the following method, including: the first terminal inquires the first priority of the first terminal from the first playing configuration information received in advance; and when the first priority is the preset maximum priority, the first terminal generates a first synchronization command.
After each terminal in the playing terminal group receives the playing command of the server, the playing configuration information of the terminal can be inquired to judge whether the terminal is the first terminal which plays the main control terminal or the second terminal which needs to wait for the synchronous command. If the terminal inquires that the priority of the terminal is the preset maximum priority P0, which indicates that the terminal is the first terminal, the terminal may generate a first synchronization command for implementing the synchronization operation. If the terminal inquires that the priority of the terminal is not the preset maximum priority P0, it indicates that the terminal is the second terminal, and the terminal needs to wait for the first synchronization command sent by the first terminal.
Step 206: the first terminal sends a first synchronization command to each of the second terminals.
In the embodiment of the present invention, after the first terminal generates the first synchronization command, the first synchronization command may be sent to each second terminal in the same slot according to the MAC addresses of other terminals in the slot group in the first play configuration information.
Optionally, in practical applications, the first synchronization command may be sent periodically to ensure that the second terminal can receive the first synchronization command, which is not specifically limited in this embodiment of the present invention.
In addition, the first terminal may start playing the playing content at the same time or after transmitting the first synchronization command.
Step 207: and the second terminal receives the first synchronization command sent by the first terminal before the countdown is finished.
In this embodiment of the present invention, before receiving the first synchronization command sent by the first terminal, the second terminal may further perform the following steps, including: inquiring the second priority of the player from the second playing configuration information received in advance; when the second priority is not the preset maximum priority, starting to count down to wait for the first synchronous command.
After each terminal in the playing terminal group receives the playing command of the server, the playing configuration information of the terminal can be inquired to judge whether the terminal is the first terminal which plays the main control terminal or the second terminal which needs to wait for the synchronous command. If the terminal inquires that the priority of the terminal is not the preset maximum priority P0, it indicates that the terminal is the second terminal, and the terminal needs to start counting down to wait for the first synchronization command sent by the first terminal.
Correspondingly, the step may specifically include: and the second terminal receives the first synchronization command sent by the first terminal before the countdown is finished. That is, the first synchronization command received by the second terminal before the countdown is finished is considered as an effective synchronization command, because the first synchronization command is received after a long delay time, the play of different terminals cannot be synchronized accurately.
Step 208: and the second terminal plays the playing content according to the playing control information from the first target frame information.
In this embodiment of the present invention, if the second terminal receives the first synchronization command sent by the first terminal before the countdown is finished, the second terminal may read the first target frame information from the first synchronization command, and then may start playing the playing content according to the playing control information from the first target frame information.
Step 209: and the second terminal generates a second synchronous command under the condition that the second terminal does not receive the first synchronous command before the countdown corresponding to the second terminal is finished, wherein the second synchronous command comprises second target frame information in the playing content.
Optionally, in a specific implementation, different second terminals may have different priorities, and the countdown duration of the second terminal may be inversely related to the priority. That is, different second terminals may have different countdown durations, and the higher the priority, the shorter the countdown duration, the lower the priority, the longer the countdown duration.
In an implementation manner, the countdown duration of the second terminal may be (Pm-Px) × T, where Pm is the priority of the second terminal, Px is the priority of the sender of the synchronization command, and T is a unit time for waiting for the synchronization command of the main control terminal when the second terminal executes the play task. If the sender of the synchronous command is the first terminal, Px is P0, and P0 is 0.
It should be noted that, if the priority is represented by 0, 1, 2, 3 … …, the formula for calculating the countdown duration may be (Pm-Px) × T, and if the priority is represented by 0, 2, 4, 6, 8 … …, the formula for calculating the countdown duration may be (Pm-Px) × T/2, that is, it may be considered that the unit time for waiting for the synchronization command of the main control terminal when the play task is executed is T/2, and the same applies. The embodiment of the present invention does not specifically limit the calculation manner of the countdown duration of the second terminal.
Specifically, the second terminal with priority P1(P1 ═ 1) has a corresponding countdown duration T, the second terminal with priority P2(P2 ═ 2) has a corresponding countdown duration 2T, the second terminal with priority P3(P3 ═ 3) has a corresponding countdown duration 3T, and so on.
When the second terminal with the priority P1 does not receive the first synchronization command before the corresponding countdown T ends, it indicates that the first terminal with the highest priority has a fault, and the fault may cause the first synchronization command to be unable to be sent or unable to be received by the second terminal, at this time, the second terminal with the priority P1 ends the countdown first, so that the second terminal with the priority P1 may become the main control terminal for playing, that is, replace the role of the original first terminal, and serve as the sender of the new synchronization command, thereby generating the second synchronization command. In a specific application, the second target frame information may be the same as or different from the first target frame information, and this is not specifically limited in this embodiment of the present invention.
Step 210: and the second terminal sends the second synchronous command to each remaining second terminal in the playing system so that each remaining second terminal starts playing the playing content from the second target frame information according to the playing control information.
In the embodiment of the present invention, the second terminal that does not receive the first synchronization command before the corresponding countdown is finished can serve as a new main control terminal to send the second synchronization command to each of the remaining second terminals in the same group of the playing terminals. If each of the remaining second terminals receives the second synchronization command before the corresponding countdown is finished, each of the remaining second terminals may start playing the playing content from the second target frame information according to the playing control information.
The countdown duration of the second terminal with the priority level P2 is 2T among the remaining second terminals, and the second terminal with the priority level P2 is the second terminal with the shortest countdown duration among the remaining second terminals, so that, if the second terminal with the priority level P1 fails to receive the second synchronization command, the second terminal with the priority level P2 will end the countdown first, so that the second terminal with the priority level P2 can become the main control terminal for playing, that is, replace the role of the original first terminal, and serve as the sender of the new synchronization command, and further generate the third synchronization command including the third target frame information, and send the third synchronization command to the remaining second terminals with the priority level lower than P2, so that the remaining second terminals with the priority level lower than P2 start playing the content from the third target frame information according to the playing control information.
In the embodiment of the invention, under the condition that the first terminal has a fault, the second terminal which finishes counting down firstly can replace the first terminal to become a main control terminal for playing and send the synchronous command to other second terminals, so that each second terminal can still realize synchronous playing, and the problem that the playing cannot be synchronous due to the fault of the first terminal can be avoided. In a similar way, when a terminal with a high priority fails, the terminal with the next priority can become a main control terminal for playing and send a synchronous command to the remaining terminals, so that other terminals can still realize synchronous playing except the failed terminal.
Taking the countdown interval T of each second terminal as an example, if the current main control terminal has no fault, each remaining second terminal may receive the synchronization command of the main control terminal before the end of the remaining shortest countdown, because if the current main control terminal has the remaining shortest countdown, the remaining second terminal will become a new main control terminal by itself without receiving the synchronization command of the main control terminal before the end of the countdown and resend the new synchronization command, therefore, under the condition that the current main control terminal has no fault, the time for each remaining second terminal to start playing and the time for the main control terminal to start playing do not exceed the countdown interval T, that is, the synchronous playing does not exceed the time difference of millisecond level, and the accuracy of the playing synchronization is high.
In addition, the user can also issue a play stop command to the first terminal and the second terminal through the server, and the play stop command can be used for stopping the countdown of the second terminal and stopping the playing of the playing content by the first terminal and the second terminal. And if the second terminal receives the playing stop command and the playing process is not finished, directly finishing playing. If the second terminal receives the playing stop command and the playing process is finished, the playing end state is maintained.
In the embodiment of the present invention, the server may send the playing content and the playing control information to the first terminal and the second terminal in the local area network, and the first terminal may generate the first synchronization command after receiving the first synchronization command, where the first synchronization command includes the first target frame information in the playing content. Then, the first terminal may send the first synchronization command to each second terminal in the local area network, and when the second terminal receives the first synchronization command before the countdown is finished, the second terminal may start playing the playing content from the first target frame information according to the playing control information. In the embodiment of the present invention, the first synchronization command for implementing synchronous playing may be sent by the first terminal to each second terminal in the same lan, and then both the first terminal and the second terminal may start playing the content from the first target frame information in the first synchronization command, thereby implementing synchronous playing. Because the synchronous operation is finished by the first terminal and the second terminal in the same local area network without being executed by a server, the synchronous operation in the local area network does not depend on the network condition between the server and the terminals, thereby improving the accuracy of the synchronous playing of a plurality of terminals. In addition, under the condition that the second terminal does not receive the first synchronization command before the countdown corresponding to the second terminal is finished, the second synchronization command can be generated and sent to each of the rest second terminals in the playing system, and the rest second terminals can play the playing content according to the playing control information from the second target frame information in the second synchronization command.
