In order to make the technical solutions in the present specification better understood by those skilled in the art, the technical solutions in the embodiments of the present specification will be clearly and completely described below with reference to the drawings in the embodiments of the present specification, and it is obvious that the described embodiments are only some embodiments of the present application, but not all embodiments.

Any embodiment or design described herein as "illustrative," "such as" or "for example" is not necessarily to be construed as preferred or advantageous over other embodiments or designs. Rather, the use of words such as "illustratively," "such as" or "for example," etc., is intended to present related concepts in a concrete fashion. In addition, unless otherwise indicated, the term "plurality" means two or more. For example, a plurality of systems means two or more systems, and a plurality of screen terminals means two or more screen terminals. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating an indicated technical feature. Thus, a feature defining "a first" or "a second" may explicitly or implicitly include one or more such feature. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless expressly specified otherwise.
The present application is described in further detail below with reference to the accompanying drawings.
As shown in fig. 1, fig. 1 is a schematic view of a scenario in which an embodiment of the present application is implemented. The system comprises a live broadcast terminal, a server and a plurality of user terminal areas. The whole scheme can be understood as that any anchor can live through live broadcast software or live broadcast through live broadcast software is carried out by some authorities, and then the live broadcast is transmitted to the user side after being transferred through the server, and in order to avoid the situation that the user side is blocked when watching live broadcast or live broadcast, the general live broadcast software can be cached, and the blocking situation is reduced. For a user side watching live broadcast, excessive cache can cause that the currently watched content and the content being live broadcast by the live broadcast side are not synchronous, so that interaction between the user side and the live broadcast side is influenced, resources of terminal equipment are occupied, and finally the terminal equipment is blocked; if the buffer memory is too small, any network jitter during live broadcast watching can bring the situation of blocking. Therefore, proper buffer memory amount needs to be selected, so that normal operation of the terminal equipment can be ensured, and the blocking condition when live broadcasting is watched can be reduced. The method combines the live broadcast terminal, the server and the user terminal to adjust the cache quantity of the user terminal, and further solves the problem.
Because of the abundance and diversity of live content, for example, live news-like live broadcast, entertainment-like live broadcast, PK-like live broadcast, etc. Because each live broadcast has specificity, the problem of blocking at the user end is considered when the live broadcast is aimed at some specificity, and the characteristics of each live broadcast are combined for analysis. For example, taking PK live broadcasting as an example, a live broadcasting terminal needs to interact with a user terminal, at this time, if a buffer schedule with an excessive buffer size is formulated to avoid the user terminal from being blocked, the live broadcasting terminal and the user terminal are not synchronous, which affects the interaction between the live broadcasting terminal and the user terminal, so that the experience of the user terminal is poor, the buffer size needs to be further limited, and the user terminal can be prevented from being blocked as much as possible while the interaction is ensured. Therefore, when different live broadcast contents are targeted, different buffer adjustment plans need to be formulated according to different live broadcast characteristics, and the following embodiments are referred to for specific embodiments.
The following description of the embodiments of the present application will be made clearly and completely with reference to the accompanying drawings of the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, not all embodiments.
Fig. 2 is a flow chart of a method for adjusting a live cache amount in one embodiment. It should be understood that, although the steps in the flowchart of fig. 2 are shown in sequence as indicated by the arrows, the steps are not necessarily performed in sequence as indicated by the arrows; the steps are not strictly limited to the order of execution unless explicitly recited herein, and the steps may be executed in other orders; and at least some of the steps in fig. 2 may include multiple sub-steps or stages that are not necessarily performed at the same time, but may be performed at different times, nor do the order in which the sub-steps or stages are performed necessarily performed in sequence, but may be performed alternately or alternately with at least a portion of the other steps or sub-steps of other steps.
As shown in fig. 2, fig. 2 is a flowchart of a method for adjusting a live cache amount according to an embodiment of the present application, where the method includes S101-S105.
Step S101, a first connection state with a live broadcast end is obtained, and a first cache amount range of a server is determined according to the first connection state.
In one example, in the live broadcast process, live broadcast data is first cached in a server and then transmitted to a user side by the server. The method can reduce the blocking and delay in network transmission and improve the smoothness and stability of live broadcasting. Meanwhile, the server cache can also realize functions of live broadcast distribution, transcoding, storage and the like, and provides more perfect support for live broadcast.
In the application, the live broadcast end may have a network problem or other problems, so that live broadcast data cannot be timely sent to the server, and live broadcast data cached by the server are limited, so that when the live broadcast end fails to timely upload the live broadcast data due to special reasons, the user end is blocked; if the cache quantity of the server is too large, the video of the live broadcast end and the video of the user end are not synchronous, so that the user experience is affected, the server processes live broadcast data of a plurality of live broadcast ends, the task quantity is large, the cache can excessively occupy the memory and the storage space of the server, and if the cache of the server is not fully utilized, the resource is wasted. Therefore, it is necessary to determine the relationship between the live end and the server, i.e. the first connection state, which can be understood as: the server acquires main influencing factors of the live broadcast terminal, wherein the main influencing factors are factors influencing that the live broadcast terminal fails to upload live broadcast data in time, and the main influencing factors can be network states; the server can formulate a buffer capacity range for the processing task amount, the memory and the like of the current server according to the main influencing factors and the self factors, wherein the buffer capacity range is the first buffer capacity range.
Acquiring a first connection state with the live broadcast end, and determining a first cache amount range of the server according to the first connection state, wherein the method further comprises the following steps: acquiring historical live broadcast data of a live broadcast terminal and change information of the number of currently connected user terminals of a server; combining historical live broadcast data and quantity change information of a live broadcast terminal and the quantity of the current connected user terminals of the server; predicting the quantity change trend of the server connected with the user terminal within a preset time length to obtain a prediction result; and adjusting the first cache amount range according to the prediction result.
In one example, since the user watching live broadcast is changing in real time, the first buffer volume plan can meet all situations, and the present solution further optimizes after the first buffer volume plan is proposed. The change of the number of live persons in any live broadcasting room can be obtained by predicting the number of live persons, the average number of watching persons in the live broadcasting terminal can be calculated by acquiring the historical live data of the live broadcasting terminal, and then the prediction is carried out by acquiring the change information of the number of live persons; of course, the server needs to process live broadcast data of a plurality of live broadcast ends, so when the first buffer quantity is adjusted, the server needs to combine the historical live broadcast data of the live broadcast ends, quantity change information and the quantity of the current connected user ends of the server to predict, then a prediction result is obtained, and the range of the first buffer quantity is adjusted according to the prediction result.
Step S102, a second connection state with each user terminal is obtained, each user terminal is divided into a plurality of user terminal areas according to the second connection state, the user terminal areas comprise at least one user terminal, and the user terminals in the same user terminal area are connected to the same server line.
In one example, the server obtains a second connection state with each user end, where the second connection state can be understood as: the server obtains the network state of each user side. The method comprises the steps that the areas where all the user terminals are located are different, the network states and the network signals are also different, the server obtains the network states of all the user terminals, all the user terminals are divided into a plurality of areas according to the network states of all the user terminals, and the user terminals with the same network states are divided into the same area. The user terminals in the same area are connected with the same server circuit. The server line can be understood as: the user side watches live broadcast through the server circuit, the server circuits in different areas are different, and the setting of different server circuits is convenient for reducing the blocking or delay when the user side watches live broadcast.
It should be noted that the second connection state includes, but is not limited to, the server obtaining the network state of each user end, and may also be other factors, for example, a terminal model of each user end, where the terminal may be a mobile phone or a computer; the terminal types of the user terminals are different, and the user terminals are set differently when watching live broadcast, for example, the current image quality of watching live broadcast is set to be high definition or standard definition or blue light. Can be set according to the actual situation. If the number of live persons watching the live persons currently is small, the area division can be performed by combining the terminal model and the network state of the user terminal, and in other cases, please refer to the above-mentioned embodiment, and redundant description is omitted here.
Acquiring a second connection state with each user terminal, dividing each user terminal into a plurality of user terminal areas according to the second connection state, and comprising: acquiring a second connection state with each user terminal; scoring each user terminal according to the second connection state to obtain the state score of each user terminal; and dividing the user terminals with the state scores in the same preset interval into the same user terminal area according to the state scores to obtain at least one user terminal area.
In one example, the user terminals are scored according to the second connection state, each connection state corresponds to a score, the lowest score is 0, the highest score is 100, and the number of the user terminal areas can be set according to the number of the user terminals. For convenience of description, two user end regions are set, screening is performed according to network signals of the user end, the signal score is not lower than 50 and is divided into an optimal region, the signal score is lower than 50 and is divided into a differential region, and the optimal region and the low region are preset regions. And acquiring the network state of the user terminal, and automatically scoring according to the network state of the user terminal, wherein the score is 0-100. It should be noted that, a network status score exists throughout each ue, and the network status score changes in real time, but the ue does not automatically adjust the ue area according to the change of the network status score, and the server needs to send an instruction to adjust.
Acquiring a second connection state with each user terminal, dividing each user terminal into a plurality of user terminal areas according to the second connection state, and further comprising: acquiring the number of the current user terminals; if the number of the current user terminals exceeds the first preset number, the user terminals in the user terminal areas are redistributed according to the number of the user terminals in the current user terminal areas; and if the number of the current user terminals is lower than the second preset number, the user terminal areas are divided again according to the number of the user terminals of each current user terminal area.
In one example, since the number of clients changes in real time, in order to reduce the occurrence of a stuck condition, the client area needs to be re-divided, and clients in the same client area are connected to the same server line, and when the areas are divided, the line needs to be re-planned. When the number of the user terminals exceeds the first preset number, the first preset number and the second preset number can be set according to the server and the server lines set by the server, the server lines are required to be combined, and the number of the users supported by each server line is limited due to limited service lines, so that when the number of the users exceeds a certain amount, the adjustment is required, and because the setting areas are carried out according to the network state before, the number of the users in different areas is different, when the number of the users is too large, the adjustment is required, so that the overload or lack of the number of the users in each area can not occur, and the stability of watching live broadcast by each user terminal is ensured to the greatest extent. Similarly, when the number of people is too small, the user terminal area can be reduced, the load of the server is reduced, resources are saved, the stability of watching live broadcast by the user is ensured, and the user experience is improved.
Step S103, according to the second connection state and the first buffer volume range of each user end area, determining the second buffer volume range of each user end area.
In one example, according to the second connection state, each ue is divided into areas, and the ues in the same area have at least one common point, where the common point may be a network state. After the area division is performed, a buffer volume range can be set in different areas according to different network states, the buffer volume ranges of the areas are different, and then the buffer volume ranges of the areas and the buffer volume ranges of the server are combined to determine the final buffer volume range of the areas, wherein the final buffer volume range is the second buffer volume range. When the second buffer volume range is formulated, not only the buffer volume of the server but also the buffer volume of each user end area are considered, so that the buffer volume of the server can be ensured to reduce the blocking of the user end in each area when watching live broadcast on the premise of not excessively occupying the memory and the storage space of the server.
Determining a second buffer capacity range of each user end area according to the second connection state and the first buffer capacity range of each user end area, including: determining a third cache amount range of each user end area according to the second connection state of each user end area; and combining the first buffer memory amount range and the third buffer memory amount range to determine a second buffer memory amount range of each user end area.
In one example, when the user end regions are divided, the user ends may be divided according to the network states of the user ends, and the user ends with similar network states may be divided into the same region. The buffer capacity range is set for each area, the buffer capacity of the user end area with good network state can be relatively less, and the buffer capacity of the user end area with poor network state can be relatively more. The buffer capacity is a third buffer capacity range, and when the buffer capacity range of each area is obtained, the final buffer capacity range of each user end area is determined by combining the first buffer capacity range of the server, and the final buffer capacity range is a second buffer capacity range.
Step S104, responding to the buffer adjustment instruction, and determining the buffer adjustment amount of the target user terminal according to the equipment information of the target user terminal corresponding to the adjustment instruction, the number of the current connected user terminals of the server and the second buffer amount range corresponding to the target user terminal.
In one example, responding to a cache amount adjustment instruction may be understood as: when the server detects that the number of times of blocking at the user side exceeds the preset number of times, the preset number of times can be set for the server or can be set for the user by himself; or when the server receives the buffer adjusting instruction sent by the user terminal, adjusting the buffer amount of the corresponding user terminal. The adjustment mode is to acquire equipment information corresponding to the target end user, wherein the equipment information is related information of terminal equipment used by the target end user when watching live broadcast and related settings performed when watching live broadcast, and the terminal equipment can be a mobile phone, a computer, a tablet and the like; the number of the servers currently connected with the user terminals, namely the number of people currently watching live broadcast; and determining the buffer adjustment quantity of the target user terminal by combining the three aspects in the second buffer quantity range corresponding to the target user terminal. There are various ways of adjusting, including but not limited to the above, and more dimensions may be combined to formulate the adjustment.
For example: when the server receives an adjusting instruction sent by the a user side of the A area, the a user side is adjusted, and the cache amount range of the A area is 5-10 seconds and is adjusted based on the adjusting instruction. Firstly, acquiring a self-set cache amount range of a user, wherein various conditions exist, the cache amount range set by the user is 5-8 seconds, and the cache amount range is within the cache amount range of the area A; or the buffer capacity range set by the user is 8-10 seconds, and part of the buffer capacity range is within the buffer capacity range of the area A; or the buffer capacity range set by the user is 2-4 seconds and is not in the buffer capacity range of the area A; the server performs different settings according to different situations, and the server is illustrated in the cache amount range of the area a, and other situations refer to the situations and are not described in detail. If the buffer capacity set by the user is 5-8 seconds, and the current number of live persons watching (the current working state of the server can be understood) and the network state of the user are combined, if the network state of the current user side is good and the number of live persons watching is less, the buffer capacity adjustment amount can be determined to be 5S after the multidimensional factors are combined. In specific practical application, the method can be set according to different conditions, and the buffer capacity of the end user is obtained through multi-dimensional combination.
In another example, the buffer adjustment amount of the target user terminal may also be adjusted according to some secondary factors. For example, when the buffer adjustment amount of any one target user terminal is obtained, optimization is continued, such as obtaining equipment information of the live broadcast terminal, hardware configuration of the live broadcast terminal, and the like; hardware configuration of the server, the number of other live broadcast and the number of audience watching live broadcast online, and the like; equipment problems of the user side, etc.; the above problem is added as an uncertainty to the amount of end user buffering. Taking the live broadcast end as an example, the equipment hardware configuration of the obtained live broadcast end is low, and although the situation that the live broadcast end does not upload live broadcast data in time does not occur, the hidden danger that the live broadcast data is not uploaded in time exists, and when the final buffer adjustment amount is prepared, the situation can be avoided, and the live broadcast data can be buffered for a period of time. Of course, the above problems can be considered in combination according to the actual situation, and the increase or decrease of the buffer amount is considered; it should be noted that, the live broadcast terminal, the server and the plurality of user terminals all have a plurality of problems, and specifically, the live broadcast terminal, the server and the plurality of user terminals can be independently formulated according to different user terminals, and no one-to-one example is needed here, and specific reference is made to the above embodiments.
The device information includes device custom information and device network information, and determining a buffer adjustment amount of the target user terminal according to the device information of the target user terminal corresponding to the adjustment instruction, the number of the current connected user terminals of the server and the second buffer amount range corresponding to the target user terminal, including: determining a preliminary cache amount range of a target user terminal according to the equipment self-defining information and the equipment network information; and determining the final buffer capacity of the target user terminal according to the initial buffer capacity range, the number of the current connected user terminals of the server and the second buffer capacity range corresponding to the target user terminal, wherein the final buffer capacity of the target user terminal is the buffer regulating capacity of the target user terminal.
In one example, the device information includes device custom information and device network information, where the device custom information may be an initial buffer amount set by the user side, i.e. a main influencing factor; the device network information is some secondary influencing factors or uncertain factors, for example, whether the basic information of the terminal device and the network have fluctuation or possible fluctuation, and the like, and the secondary factors and the uncertain factors have a plurality of secondary factors and can be specifically set according to actual conditions and different users, and the users can also select the secondary factors and the uncertain factors by themselves, so that excessive details are not needed. Determining a primary buffer volume range of the target user terminal according to the device custom information and the device network information, and then determining a final buffer volume of the target user terminal by combining the primary buffer volume range, the number of the current connected user terminals of the server and the second buffer volume range corresponding to the target user terminal, wherein the determination method is described in the above embodiment, and specifically please refer to the above embodiment, and the final buffer volume is the buffer adjustment volume of the target user terminal.
The device network information comprises network information, terminal information and setting information, and the determining the preliminary buffer memory range of the target user terminal according to the device custom information and the device network information comprises the following steps: determining an initial cache amount range according to the self-defining information of the equipment; according to the equipment network information, distributing the network information as a first weight; distributing terminal information as a second weight; distributing the setting information as a third weight; combining the first weight, the second weight and the third weight to determine an adjusting range; and determining the initial buffer capacity range of the target user terminal by combining the initial buffer capacity range and the adjustment range.
In one example, the device network information includes network information, terminal information, and setting information, and it should be noted that the device network information includes, but is not limited to, the above three types of information, which are exemplified here. Network information and network condition information of a target user terminal; the terminal information is the terminal equipment of the target user end, such as the running memory quantity of the terminal equipment; the setting information is a requirement set by the user side when watching live broadcast through live broadcast software, and if the image quality is high definition. And then the three aspects are distributed with weights, and the purpose of distributing the weights by a user according to actual conditions or distributing the weights by a server and batching the weights is to optimize the initial buffer memory amount range on the basis of the initial buffer memory amount range after determining the initial buffer memory amount range, wherein the initial buffer memory amount range is the buffer memory amount range self-defined by the user.
For example, the allocation network information is 3 second buffer, the terminal information is 2 second buffer, and the setting information is 1 second buffer, and the time allocation can be set by itself, and then the total weight of the network information, the terminal information, and the setting information is 1. For example, when there is an unstable network quality at the user end, the weight ratio of the network information may be set to 80%, and the buffering time of the network information is then
Second, wherein the second is; the remaining terminal information and the setting information are sequentially distributed for the remaining 20%, if the terminal equipment is good, namely the terminal information has no influence, the terminal information can be selected to be removed, namely the terminal information accounts for 0%; the set information is 20% in proportion, and the buffer time of the set information is +.>
Second, wherein the second is; the final conditioning time is 0.2+2.4=2.6 seconds; at this time, if the initial buffering capacity is 5-10 seconds, the final buffering capacity is 5-12.6 seconds, and the final buffering capacity is the initial buffering capacity range of the target user terminal.
Step S105, the buffer adjustment amount is sent to the target user end, so that the target user end adjusts the buffer amount according to the buffer adjustment amount.
In one example, when the buffer adjustment amount is obtained, the buffer adjustment amount is sent to the target ue, so that the target ue adjusts the buffer amount according to the buffer adjustment amount. Of course, the present application only sends the adjustment scheme, and does not directly change the buffer capacity of the user, whether to select to change and how much to change depend on the individual user, and the user adjusts according to the actual situation when receiving the buffer capacity sent by the server.
In another example, when the server pushes a buffer adjustment scheme to the client, it needs to consider whether there are special cases, where the special cases may cause the client to get stuck. Therefore, comprehensive consideration is needed to reduce the situation that the user end is blocked as much as possible. In general, special situations exist in the live broadcast end, the server and the user end, for example, for the live broadcast end, the hardware equipment performance is poor, the network equipment is problematic, the live broadcast end has power failure, and the like, which may cause the user end to be blocked; special conditions exist for the server side, such as power failure and poor performance of hardware equipment of the server side may cause the client side to be blocked; the same problem also exists for the user side. The above problems are that the user end is blocked due to some external factors or uncertain factors, so that the buffer amount pushed to the user can be adjusted according to the requirement when the buffer plan is formulated. For example, the server has determined that the cache adjustment plan pushed to a client is 5S, and in consideration of special cases, the adjustment can be performed again based on the cache adjustment plan. It should be noted that, the specific factors of the live broadcast terminal, the server and the user terminal may be considered, or any one or more terminals may be considered, and may be selected according to the actual situation, for convenience of description, here, an example is taken, where it is detected that the live broadcast terminal currently being watched by the user terminal has multiple power failures or other specific situations in a week, and the caching plan may be adjusted again for such situations, for example, may be adjusted to 7S. Thus, the experience of the user side can be better improved.
