In the present specification, a data push method is provided, and the present specification relates to a secondary side, two primary sides, two data push systems, a computing device, and a computer-readable storage medium, which are described in detail in the following embodiments one by one.
Fig. 1 shows a flowchart of a first data pushing method provided in an embodiment of the present specification, which is applied to a secondary side, and as shown in fig. 1, the method specifically includes the following steps:
step 102: and responding to a data acquisition request sent by the master end to acquire the first direct broadcasting data.
Specifically, the main end is used for interacting with the auxiliary end and the live broadcast server, and in practical application, the main end can be a live broadcast client used by a main broadcast; the auxiliary end is used for providing live broadcast data for the main end according to the requirement of the main end, namely the auxiliary end can assist the main end to push the live broadcast data to the live broadcast server. In addition, the first live broadcast data is the live broadcast data acquired by the auxiliary terminal; the data acquisition request is a request for indicating the auxiliary terminal to start acquiring corresponding first direct broadcast data, the data acquisition request may carry a live broadcast data identifier, and the auxiliary terminal may acquire the corresponding first direct broadcast data according to the live broadcast data identifier carried in the data acquisition request when receiving the data acquisition request sent by the main terminal.
In an optional implementation manner of this embodiment, before the secondary side receives the data acquisition request sent by the primary side, the secondary side further needs to establish a connection with the primary side first, so before the secondary side acquires the live data in response to the data acquisition request sent by the primary side, the method further includes:
sending a connection information acquisition request to an intermediate node, wherein the connection information acquisition request carries a first identity mark;
receiving connection information returned by the intermediate node based on a second identity identifier and the first identity identifier, wherein the second identity identifier is an identity identifier carried in the connection information sent by the master terminal to the intermediate node;
and initiating a connection request according to a network address carried in the connection information, wherein the network address is an address carried in the connection information sent to the intermediate node by the master terminal.
Specifically, the intermediate node is used for storing connection information required by the connection between the main terminal and the auxiliary terminal; the first identity mark is the identity mark of the auxiliary end, and the second identity mark is the identity mark of the main end. It should be noted that, when the auxiliary terminal acquires the connection information from the intermediate node, the intermediate node may also verify the identity of the auxiliary terminal, so that the auxiliary terminal needs to carry the first identity of the auxiliary terminal when sending the connection information acquisition request, the intermediate node may verify the first identity of the auxiliary terminal based on the second identity of the main terminal, and only when the auxiliary terminal uses the same identity, the connection information of the main terminal may be acquired from the intermediate node, thereby ensuring the security of the main terminal.
During actual implementation, the intermediate node receives and stores the connection information sent by the main terminal, and acquires a second identity identifier in the connection information; the intermediate node receives a connection information acquisition request sent by the auxiliary terminal, wherein the connection information acquisition request carries a first identity; and the intermediate node returns the connection information to the auxiliary terminal under the condition that the first identity identification is the same as the second identity identification.
In practical application, the intermediate node can expose the domain name of the wide area network in advance, and after the auxiliary terminal obtains the domain name exposed by the intermediate node, the auxiliary terminal can establish connection with the intermediate node through an http protocol. And then, the auxiliary terminal can acquire the connection information of the main terminal from the intermediate node based on the first identity, and then send a connection request to a network address carried in the connection information.
In addition, if the auxiliary terminal acquires the connection information of the main terminal, a connection request can be sent to the main terminal according to the connection information, so that connection with the main terminal is attempted, if the connection is successful, subsequent data interaction can be carried out, if the connection is failed, the connection information can be acquired from the intermediate node again according to a fixed time interval, and connection is attempted with the main terminal according to the newly acquired connection information until the number of connection failures reaches a preset number.
In an optional implementation manner of this embodiment, after the connection between the secondary end and the primary end is successful, the secondary end may further send keep-alive information to the primary end to determine availability of the connection, that is, after the connection between the secondary end and the primary end is established, the method further includes:
sending first keep-alive information to the main end, and receiving second keep-alive information sent by the main end;
and under the condition that the second keep-alive information is not received in a second preset time length, disconnecting the main end.
Specifically, the keep-alive information is information for identifying an active state of the auxiliary terminal, the first keep-alive information is information sent by the auxiliary terminal to the main terminal to notify the main terminal of the active state, the second keep-alive information is information sent by the main terminal to the auxiliary terminal, and the auxiliary terminal can know the active state of the main terminal through the second keep-alive information. If the secondary terminal does not receive the keep-alive information sent by the main terminal within the second preset time length, the fact that the main terminal is abnormal or the connection with the main terminal is abnormal is indicated, so that the connection with the main terminal can be disconnected, the connection can be timely disconnected when a fault occurs, and resources are saved.
Step 104: and determining a first main terminal time corresponding to the first direct broadcasting data according to the first auxiliary terminal time of the first direct broadcasting data.
Specifically, on the basis of acquiring first broadcast data in response to a data acquisition request sent by a master, further, a first master time corresponding to the first broadcast data is determined according to a first auxiliary time for acquiring the first broadcast data.
In an optional implementation manner of this embodiment, since the primary end and the secondary end use respective local clocks that are not affected by adjustment of the system clock, that is, the primary end and the secondary end use respective local times (such as boot time), after the primary end and the secondary end successfully establish a connection, the secondary end needs to perform time synchronization before sending data to the primary end, so as to ensure accuracy of time and avoid inconsistency of data due to time confusion. During specific implementation, before determining the first main-end time corresponding to the first broadcast data according to the first auxiliary-end time for obtaining the first broadcast data, the method further includes:
sending a time synchronization packet to the main terminal every a first preset time length, wherein the time synchronization packet carries second auxiliary terminal time to be sent;
receiving a time synchronization response packet sent by the master end, and recording a third auxiliary end time for receiving the time synchronization response packet, wherein the time synchronization response packet carries the second auxiliary end time, the second master end time and a third master end time for sending the time synchronization response packet, and the second master end time is the time for receiving the time synchronization response packet by the master end;
and determining the time offset corresponding to the time-setting packet according to a first time difference between the second main end time and the second auxiliary end time and a second time difference between the third main end time and the third auxiliary end time.
Specifically, the first preset duration is a preset time interval for sending the time tick packet, that is, how long a time tick packet is sent. For example, the first predetermined period of time may be 1 minute, 5 minutes, 10 minutes, etc.
It should be noted that the auxiliary end sends a time-tick packet to the main end every other first preset time, and then determines the time offset corresponding to the time-tick packet according to the relevant time of the time-tick packet, that is, the time offset corresponding to the time-tick packet is obtained every time a time-tick packet is sent.
In specific implementation, for any one time-tick packet that is sent, the time offset corresponding to the time-tick packet is determined according to a first time difference between the second master time and the second slave time, and a second time difference between the third master time and the third slave time, which can be implemented by the following formula (1):
offset n ＝(time receive -time originate +time transmit -time response )/2 (1)；
wherein the offset n Indicating the time offset, time, corresponding to the nth tick packet receive Representing the second master time, time originate Representing the second secondary time, time transmit Representing the third master time, time response Indicating a third secondary terminal time.
For example, assuming that the first preset time duration is 5 minutes, after the connection between the primary end and the secondary end is established, the primary end immediately sends a first time synchronization packet to the secondary end, and calculates a corresponding time offset to be offset according to the time synchronization packet 1 =0.4 seconds; after 5 minutes, the master end sends a second time-tick packet to the slave end, and the corresponding time offset is obtained by calculation according to the time-tick packet and is offset 2 =0.2 seconds; and 5 minutes later, the master end sends a third time tick packet to the slave end, and the corresponding time offset is obtained by calculation according to the time tick packet 3 =0.3 seconds; and after another 5 minutes, the master end sends a fourth time-setting packet to the slave end, and the corresponding time offset is obtained by calculation according to the time-setting packet 4 =0.1 sec; and after another 5 minutes, the master end sends a fifth time-tick packet to the slave end, and the corresponding time offset is calculated and obtained according to the time-tick packet and is offset 5 =0.3 seconds.
In an optional implementation manner of this embodiment, after a period of time, time offsets corresponding to a plurality of time tick packets are obtained respectively, and then a current time tick offset between the primary end and the secondary end may be determined according to the time offsets corresponding to the plurality of time tick packets sent in the period of time, so after determining the time offsets corresponding to the time tick packets, the method further includes:
under the condition that time offset corresponding to n time-setting packets is determined, current time-setting offset between the main end and the auxiliary end is determined according to the time offset corresponding to the 1 st time-setting packet and the time offset corresponding to the m th time-setting packet, wherein n is greater than or equal to 1, m is smaller than or equal to n, and m and n are both natural numbers.
Specifically, m is a parameter preset in the system and represents the number of time offsets required for calculating the current time synchronization offset between the main terminal and the auxiliary terminal, and since m is less than or equal to n and is a parameter preset by the system, the current time synchronization offset between the main terminal and the auxiliary terminal can be calculated only after the time offsets corresponding to n time synchronization packets are obtained, and it is required to ensure that n is greater than or equal to m.
In an optional implementation manner of this embodiment, the current time synchronization offset between the primary end and the secondary end is determined according to the time offset corresponding to the 1 st time synchronization packet to the time offset corresponding to the m th time synchronization packet, and a specific implementation process may be:
and calculating a first average value of the time offset corresponding to the 1 st time tick packet to the time offset corresponding to the mth time tick packet, and determining the first average value as the current time tick offset between the main terminal and the auxiliary terminal.
In a specific implementation, the following formula (2) can be expressed:
offsetavg 1，m ＝offset 1 +offset 2 +...+offset m (2)；
wherein, offsetavg 1，m Indicating the time offset corresponding to the 1 st time pair packet to the first mean, offset, of the time offset corresponding to the m-th time pair packet 1 Indicating the time offset, corresponding to the first time-pair packet 2 Indicating the time offset, corresponding to the second pair of time packets m Indicating the time offset corresponding to the mth time pair packet.
Along with the above example, assuming that m is 3 and n is 5, that is, data of 3 time offsets are needed to calculate the current time offset between the primary and secondary terminals, the current calculation obtains 5 time offsets, which are respectively offset 1 =0.4 sec, offset 2 =0.2 seconds, offset 3 Offset of =0.3 seconds 4 =0.1 sec and offset 5 =0.3 sec, calculated at this time
Figure BDA0002964134530000091
That is, the current time setting offset is calculated to be 0.3 seconds.
In this specification, the time offset corresponding to the 1 st time-tick packet to the time offset corresponding to the m-th time-tick packet may be integrated by calculating an average value, so as to obtain the current time-tick offset between the main terminal and the auxiliary terminal. Of course, in practical application, the time offset corresponding to the 1 st time tick packet to the time offset corresponding to the m th time tick packet may also be synthesized through other manners, such as calculating a weighted average, calculating an average of a difference between a maximum time offset and a minimum time offset, and the like, which is not limited in this specification.
In an optional implementation manner of this embodiment, after the current time synchronization offset between the primary end and the secondary end is obtained through calculation, the secondary end may continue to send the time synchronization packet to the primary end, continue to perform time synchronization, and determine whether the current time synchronization offset between the primary end and the secondary end needs to be updated according to a time offset corresponding to a time synchronization packet that is sent subsequently, that is, after the current time synchronization offset between the primary end and the secondary end is determined according to a time offset corresponding to a 1 st time synchronization packet to a time offset corresponding to an m th time synchronization packet, the method further includes:
under the condition that the time offset corresponding to the kth time tick packet is determined, whether the current time tick offset between the main end and the auxiliary end is updated or not is determined according to the time offset corresponding to the jth time tick packet to the time offset corresponding to the kth time tick packet, wherein j is equal to k-m +1, k is larger than n, and j and k are both natural numbers.
Specifically, the kth time tick packet is the time tick packet after the nth time tick packet, the consistency of the time tick packet data after the nth time tick packet can be determined according to the time shift corresponding to the jth time tick packet to the time shift corresponding to the kth time tick packet, and whether to update the current time tick shift between the main terminal and the auxiliary terminal is determined according to the data consistency.
In an optional implementation manner of this embodiment, whether to update the current time synchronization offset between the primary end and the secondary end is determined according to the time offset corresponding to the j-th time synchronization packet to the time offset corresponding to the k-th time synchronization packet, and a specific implementation process may be as follows:
calculating the deviation value of the time deviation corresponding to the jth time-setting packet to the time deviation corresponding to the kth time-setting packet;
determining not to update the current time synchronization offset between the main terminal and the auxiliary terminal under the condition that the deviation value is greater than or equal to a preset threshold value;
and under the condition that the deviation value is smaller than a preset threshold value, updating the current time synchronization deviation between the main end and the auxiliary end according to the time deviation corresponding to the jth time synchronization packet to the time deviation corresponding to the kth time synchronization packet.
Specifically, the preset threshold is a parameter preset in the system, and is configured to determine whether a time offset corresponding to the time tick packet determined after the nth time tick packet is too large, that is, whether the consistency of the data of the time tick packet after the nth time tick packet is poor, determine not to update the current time tick offset between the primary end and the secondary end in the case of poor data consistency, and use the new data to recalculate the current time tick offset in the case of good data consistency, even if the time tick offset calculated by using the old data is continuously used as the current time tick offset (that is, the first mean value is continuously determined as the current time tick offset between the primary end and the secondary end).
It should be noted that the offset value is used to indicate whether the time offset corresponding to the jth time tick packet to the kth time tick packet is too large, that is, the consistency of the data of the jth time tick packet to the kth time tick packet is high or low. In specific implementation, the variance of the time offset corresponding to the jth time-tick packet to the time offset corresponding to the kth time-tick packet may be calculated, and whether to update the current time-tick offset between the primary end and the secondary end is determined according to the relationship between the variance and a preset threshold. Certainly, in practical application, the calculation may also be performed in other manners, for example, a standard deviation of a time offset corresponding to a j-th time tick to a time offset corresponding to a k-th time tick may be calculated, and whether to update the current time tick between the primary end and the secondary end is determined according to a relationship between the standard deviation and a preset threshold, which is not limited in this specification.
The current time synchronization offset between the main terminal and the auxiliary terminal is updated according to the time offset corresponding to the jth time synchronization packet to the time offset corresponding to the kth time synchronization packet, and the specific implementation process may be as follows:
and calculating a second average value of the time offset corresponding to the jth time pair packet to the time offset corresponding to the kth time pair packet, and updating the second average value to be the current time pair offset between the primary end and the secondary end.
For example, assuming that n is 10 and m is 6, the current time pair offset offsetavg is calculated from the time offset corresponding to the 1 st time pair packet to the time offset corresponding to the 6 th time pair packet 1，6 (ii) a Thereafter, the offset is obtained for the 11 th calculation 11 Determine offsetvar 11-6+1，11 I.e. offset var 6，11 Whether or not it is greater than a preset threshold (where offsetvar) 6，11 The variance indicating the time offset from the 6 th packet to the 11 th packet) is greater than the variance, which indicates that the consistency of the time offset from the 6 th packet to the 11 th packet is poor and the offset is still set 1，6 As the current time setting offset, otherwise, the current time setting offset is updated to offsetavg 6，11 (i.e., the time offset corresponding to the 6 th packet pair is the average of the time offsets corresponding to the 11 th packet pair).
In this specification, after the current time synchronization offset between the main terminal and the auxiliary terminal is obtained through calculation, time synchronization can be continuously performed, the current time synchronization offset between the main terminal and the auxiliary terminal is updated in real time, and accurate time synchronization of the main terminal and the auxiliary terminal is ensured, so that consistency of data between the main terminal and the auxiliary terminal is ensured.
It should be noted that, after receiving the data acquisition request sent by the main end, the auxiliary end needs to acquire corresponding live broadcast data, and the auxiliary end may directly acquire and generate the live broadcast data through a camera device carried by the auxiliary end, or may acquire corresponding data with the aid of other push devices and then process the data to obtain the live broadcast data. Certainly, in practical application, the auxiliary terminal may also be a device in other forms, and the live data that needs to be sent is obtained in other forms, which is not limited in this specification.
In an optional implementation manner of this embodiment, the determining, according to the first secondary end time of the obtained first broadcast data, a first primary end time corresponding to the first broadcast data may be implemented as follows:
and determining the sum of the first auxiliary terminal time and the current time setting offset as a first main terminal time corresponding to the first broadcast data.
In actual implementation, determining the sum of the first secondary time and the current time tick as the first primary time corresponding to the live broadcast data may be represented by the following formula (3):
time main ＝time assist +offset system (3)；
wherein, time main Representing the first master time, time assist A first secondary time, offset, representing the generation of first direct broadcast data system Indicating the current time tick offset.
It should be noted that, when calculating the time offset corresponding to the time tick packet, the time tick time is subtracted from the time tick of the master end, so that the current time tick offset between the master end and the slave end obtained by subsequent calculation is the time that the slave end is later than the master end, and the current time offset can be added subsequently on the basis of the time tick of the slave end, so as to obtain the corresponding time tick of the master end. In practical application, of course, when calculating the offset time corresponding to the time tick packet, the time tick time may also be obtained by subtracting the time tick of the main end from the time tick of the auxiliary end, so that the current time tick offset between the main end and the auxiliary end obtained by subsequent calculation is the time tick that is earlier than the time tick of the main end by the auxiliary end, and the current time tick offset may be subsequently subtracted on the basis of the time tick of the auxiliary end, so as to obtain the corresponding time tick of the main end, which is not limited in this specification.
Step 106: and carrying the first main terminal time in the first direct broadcasting data and sending the first direct broadcasting data to the main terminal.
Specifically, on the basis of determining a first main terminal time corresponding to the first direct broadcast data according to a first auxiliary terminal time for acquiring the first direct broadcast data, the first main terminal time is further carried in the first direct broadcast data and sent to the main terminal.
It should be noted that, when the auxiliary end acquires the first live broadcast data, the local time (i.e., the first auxiliary end time) for acquiring the first live broadcast data is recorded, and the local time (the first auxiliary end time) of the auxiliary end is converted into the local time (the first main end time) of the main end according to the current time synchronization offset between the main end and the auxiliary end, and then is sent to the main end, so that the main end time is carried in the live broadcast data received by the main end.
In the data push method provided by this specification, the auxiliary terminal may obtain the first broadcast data, determine corresponding first main terminal time according to the auxiliary terminal time and the main terminal time synchronization of the auxiliary terminal and the main terminal, and carry the first main terminal time in the obtained first broadcast data, so that the subsequent main terminal may receive the first broadcast data sent by at least two auxiliary terminals, and push the first broadcast data to the live broadcast server after performing time alignment on the first broadcast data according to the first main terminal time carried in the first broadcast data. Therefore, the time of the main end is carried in the first live broadcast data received by the main end, the main end and the auxiliary ends accurately time-synchronize, the consistency of the data between the main end and the auxiliary ends is ensured, the calculation and the processing of the live broadcast data are dispersed to be executed by the auxiliary ends, the calculation pressure of the main end is reduced, the energy consumption of the main end is reduced, and the performance requirement of the main end is correspondingly reduced; and secondly, the main end can be simultaneously connected with a plurality of auxiliary ends, so that the method has good scale expandability and can fully utilize the network bandwidth.
Fig. 2 shows a flowchart of a second data pushing method provided according to an embodiment of the present specification, which is applied to a master, and as shown in fig. 2, the method specifically includes the following steps:
step 202: and sending data acquisition requests to at least two auxiliary terminals.
It should be noted that the main end may acquire different live broadcast data from the at least two auxiliary ends, so that when the main end sends a data acquisition request to the auxiliary ends, the main end may carry an identifier of the required live broadcast data in the data acquisition request, so that after a subsequent auxiliary end receives the data acquisition request, the subsequent auxiliary end may collect corresponding live broadcast data according to the identifier of the required live broadcast data of the main end, that is, the identifiers of the required live broadcast data carried in the data acquisition requests sent by the main end to the different auxiliary ends may be different.
For example, the primary end sends a data acquisition request 1 to the secondary end a, where the data acquisition request 1 carries a time identifier t1, and the secondary end a can acquire live data before the time t1 when receiving the data acquisition request 1; the main terminal sends a data acquisition request 2 to the auxiliary terminal B, the data acquisition request 2 carries time marks t1 and t2, and the auxiliary terminal B acquires live broadcast data between the time t1 and the time t2 when receiving the data acquisition request 2.
In an optional implementation manner of this embodiment, when the data push system includes a plurality of auxiliary terminals, the main terminal needs to determine to which auxiliary terminals to send the data acquisition request, that is, the main terminal needs to select a part or all of the auxiliary terminals that execute the data generation task from the plurality of auxiliary terminals included in the data push system, so before the main terminal sends the data acquisition request to at least two auxiliary terminals, the method further includes:
and determining the auxiliary end for receiving the data acquisition request according to the load of each of the at least two auxiliary ends.
It should be noted that the primary end may determine, according to the load of the secondary end, that is, a live data generation task that has not been executed, which secondary ends execute a new live data generation task, that is, may determine, through load balancing, a secondary end that receives the data acquisition request (that is, a secondary end that executes a live data generation task).
For example, the data push system includes 5 auxiliary terminals, and if the main terminal has 5 requirements for generating live broadcast data, the main terminal sends data acquisition requests to the 5 auxiliary terminals respectively. Then, assuming that the master has 3 requirements for generating live data, at this time, since only one task for generating live data is being executed by each of the 5 slave terminals, that is, the loads are the same, at this time, 3 slave terminals (slave terminal 1, slave terminal 2, and slave terminal 3) may be randomly selected from the 5 slave terminals, and the data acquisition request is sent to the selected 3 slave terminals again. Later, assuming that the master peer has 2 demands for generating live broadcast data, at this time, according to the load, the data acquisition request is sent again to the slave peers (slave peer 4 and slave peer 4) other than the 3 slave peers among the 5 slave peers.
In an optional implementation manner of this embodiment, before the main end sends the data obtaining request to the at least two auxiliary ends, the main end further needs to establish a connection with the at least two auxiliary ends first, and thus before sending the data obtaining request to the at least two auxiliary ends, the method further includes:
sending connection information to an intermediate node, wherein the connection information comprises a network address and a second identity;
monitoring a connection request at the network address;
and responding to the monitored connection request to establish connection with the auxiliary terminal, wherein the connection request is initiated by the auxiliary terminal based on the network address acquired by the intermediate node based on the first identity.
Specifically, the intermediate node is used for storing connection information required by the connection between the main terminal and the auxiliary terminal, the intermediate node can expose a domain name of the wide area network of the intermediate node in advance, and the main terminal and the auxiliary terminal can establish connection with the intermediate node through an http protocol after acquiring the domain name exposed by the intermediate node. Then, the master may send connection information carrying a network Address to the intermediate node, and start monitoring on the network Address, where the network Address may be an available IP Address (Internet Protocol Address) of the master, that is, an available port. After the connection between the auxiliary terminal and the intermediate node is established, the connection information of the main terminal can be acquired from the intermediate node, and then the connection request is sent to the network address carried in the connection information.
It should be noted that the connection information sent by the master to the intermediate node carries the second identity identifier of the master, and the connection information of the master can be acquired from the intermediate node only by using the same identity identifier by the slave, thereby ensuring the security of the master.
In addition, if the main terminal and the auxiliary terminal are in the local area network, the connection information sent by the main terminal to the intermediate node is the local area network information, and if the main terminal and the auxiliary terminal are in the wide area network, the connection information sent by the main terminal to the intermediate node is the wide area network information. In addition, the intermediate node is typically in a wide area network with the primary and secondary sides, i.e., the intermediate node is typically accessed through a wide area network domain name.
In an optional implementation manner of this embodiment, after the main end and the auxiliary end are successfully connected, the main end may further send keep-alive information to the auxiliary end to determine availability of the connection, that is, after the main end and the auxiliary end establish the connection, the method further includes:
sending second keep-alive information to the auxiliary terminal, and receiving first keep-alive information sent by the auxiliary terminal;
and under the condition that the first keep-alive information is not received in a second preset time length, disconnecting the auxiliary terminal.
It should be noted that the primary end may send second keep-alive information to the secondary end to notify the active state of the secondary end itself, and the first keep-alive information is information sent by the secondary end to the primary end, and through the first keep-alive information, the primary end may learn the active state of the secondary end. If the main terminal does not receive the keep-alive information sent by the auxiliary terminal within the second preset time length, the fact that the auxiliary terminal is abnormal possibly or the connection with the auxiliary terminal is abnormal is indicated, so that the connection with the auxiliary terminal can be disconnected, the connection can be timely disconnected when a fault occurs, and resources are saved.
Step 204: and receiving first direct-broadcasting data sent by the at least two auxiliary terminals in response to the data acquisition request, wherein the first direct-broadcasting data carries first main terminal time determined by the auxiliary terminals according to the first auxiliary terminal time for acquiring the first direct-broadcasting data.

Step 206: and according to the first main terminal time carried in the first live data, carrying out time alignment on the received first live data, and pushing the time-aligned first live data to a live broadcast server.
Specifically, on the basis of receiving first live broadcast data sent by the at least two auxiliary terminals in response to the data acquisition request, further, according to the first main terminal time carried in the first live broadcast data, time alignment is performed on the received first live broadcast data, and the first live broadcast data after time alignment is pushed to a live broadcast server.
It should be noted that the local time (i.e., the time of the first main terminal) of the main terminal is carried in the first broadcast data sent by each auxiliary terminal to the main terminal, and after the main terminal receives the first broadcast data, the main terminal does not need to convert the time in the first broadcast data, but can directly sequence the first broadcast data according to the time carried in the first broadcast data (i.e., time alignment), thereby avoiding time confusion and data errors, and ensuring the consistency of data between the main terminal and each auxiliary terminal. And time synchronization between the main end and the auxiliary ends is carried out at each auxiliary end in a scattered manner, the main end only needs to receive the first direct broadcasting data and sequence according to the time carried in the first direct broadcasting data, excessive processing operation is not needed, the calculation pressure of the main end is reduced, the energy consumption of the main end is reduced, and therefore the performance requirement on the main end is reduced.
For example, the time of the first auxiliary end, which generates the live data 1, of the auxiliary end a is 1 minute 25 seconds, and the current time synchronization offset between the auxiliary end a and the main end is 10 seconds, so that the corresponding time of the first main end is 1 minute 35 seconds; the first auxiliary end time of the auxiliary end B for generating the live data 2 is 1 minute 28 seconds, the current time setting offset between the auxiliary end B and the main end is 5 seconds, and then the corresponding first main end time is 1 minute 33 seconds; the first auxiliary terminal time of the auxiliary terminal C for generating the live data 3 is 1 minute 30 seconds, and the current time synchronization offset between the auxiliary terminal C and the main terminal is 1 second, so that the corresponding first main terminal time is 1 minute 31 seconds. After receiving the live data 1, the live data 2 and the live data 3, the main terminal performs time alignment (i.e., sequencing) on the live data 1, the live data 2 and the live data 3 according to the time of the first main terminal carried by the main terminal, i.e., 1 minute 35 seconds, 1 minute 33 seconds and 1 minute 31 seconds, so as to obtain the live data 3, the live data 2 and the live data 1.
Furthermore, after the main terminal time aligns the first live data according to the main terminal time carried in the first live data, the main terminal can push the time-aligned first live data to the live broadcast server, and the live broadcast server pushes the first live data to each watching client terminal requesting to watch live broadcast, so that a user can watch live broadcast.

Therefore, the time of the main end is carried in the first live broadcast data received by the main end, the main end and the auxiliary ends accurately time-synchronize, the consistency of the data between the main end and the auxiliary ends is guaranteed, the calculation and the processing of the live broadcast data are dispersed to be executed by the auxiliary ends, the calculation pressure of the main end is reduced, the energy consumption of the main end is reduced, and the performance requirement of the main end is correspondingly reduced; and secondly, the main end can be simultaneously connected with a plurality of auxiliary ends, so that the method has good scale expandability and can fully utilize the network bandwidth.

step 302: and acquiring second live broadcast data, and sending a data acquisition request to at least one auxiliary terminal.
Specifically, the second live broadcast data is live broadcast data acquired or collected by the host. It should be noted that, besides the secondary side is used to obtain the live data, the primary side itself can also obtain the corresponding live data. In addition, the data acquisition request sent by the main terminal to the auxiliary terminal can carry a live data identifier to indicate the auxiliary terminal to acquire corresponding first live data.
For example, the main terminal sends a data acquisition request 1 to the auxiliary terminal a, where the data acquisition request 1 carries a time identifier t1, and the auxiliary terminal a can acquire first direct-broadcast data before the time t1 when receiving the data acquisition request 1; the main terminal sends a data acquisition request 2 to the auxiliary terminal B, the data acquisition request 2 carries time marks t1 and t2, the auxiliary terminal B acquires first live broadcast data between the time t1 and the time t2 when receiving the data acquisition request 2, and at the moment, the main terminal can acquire second live broadcast data after the time t 2.
