[0043] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0044] As a bridge between media sources and media demanders, gateways play an increasingly important role in media playback, such as live streaming. They enable the new generation of multicast technology to carry a large number of Internet live broadcasts, providing the software and hardware foundation for the rapid development of the Internet live streaming industry.

[0045] The core goals of acquiring multicast live media information are low latency, low bandwidth consumption, low computing power consumption, low packet loss, and low multicast multiplexing rate. However, for existing methods for local scheduling of multicast live media information acquisition, these goals are mutually exclusive. For example, to achieve low latency, the gateway deployment location needs to be close to the user. In this scenario, the gateway's bandwidth consumption, computing power consumption, packet loss, and multicast multiplexing rate will all increase. Therefore, existing local scheduling methods are unable to provide a scheduling method that achieves all of these goals for existing multicast services. Based on this, the embodiments of the present application provide a method for acquiring media information to improve the above-mentioned technical problems.

[0046] The media information acquisition method provided in the embodiment of the present application can be applied to situations involving how to execute media information acquisition in any field. The method can be executed by a scheduling server. For example, the media information acquisition method provided in the embodiment of the present application can be applied in the application environment shown in Figure 1. Among them, the media demand end 101 communicates with the scheduling server 102 through the communication network 104. The data storage system 103 can store data that the scheduling server 102 needs to process. The data storage system 103 can be integrated on the scheduling server 102, or it can be placed on the cloud or other network servers. Specifically, in the case of a media information playback request from the media demand end, the scheduling server 102 responds to the media information playback request from the user end, obtains the gateway pool of the media source corresponding to the media information to be played, selects the target gateway from the gateway pool based on the total usage rate of the gateway pool, and then feeds back the gateway information of the target gateway to the media demand end; wherein, the gateway information is used for the media demand end to locate the target gateway so as to obtain the media information to be played through the target gateway. Furthermore, the scheduling server 102 may interact with the media demand end 101 to feed back the result of executing the media information acquisition task to the media demand end 101 , which is then displayed to relevant personnel by the media demand end 101 .

[0047] The media demand side 101 may include, but is not limited to, various personal computers, laptops, smartphones, tablets, IoT devices, and portable wearable devices. IoT devices may include smart speakers, smart TVs, smart air conditioners, and smart car devices. Portable wearable devices may include smart watches, smart bracelets, and head-mounted devices. The scheduling server 102 may be implemented as a standalone server or a server cluster consisting of multiple servers.

[0048] In one embodiment, FIG2 is a flow chart of a method for obtaining media information according to an embodiment of the present application, and is described by taking the method applied to the scheduling server in FIG1 as an example. The method includes the following steps:

[0049] S201 , in response to a media play request sent by a media demand end, obtaining a gateway pool of a media source corresponding to media information to be played.

[0050] In one embodiment, a media demander can be a user terminal that needs to obtain media information from a media source, such as a mobile phone, computer, or tablet computer. The present invention does not limit the type of user terminal. A media source can be a device that generates media information, such as an audio player or video player. The present invention also does not limit the type of device. Optionally, each media source corresponds to a gateway pool, which contains one or more gateways.

[0051] Furthermore, the media information play request may be a request input by a user through a media demand side for executing a media information acquisition task. The media information to be played may be information carried in the media information play request and required to be acquired by the media demand side from a media source.

[0052] In one embodiment, when a media information playback request is received from a media demand end and a media information playback task in the media information playback request needs to be executed, a gateway pool of a corresponding media source is selected according to the media information to be played carried in the media information playback request.

[0053] It should be noted that the media in the embodiments of the present application can be live broadcast, video, news, etc. In the case of live broadcast, the media demand end is the live broadcast demand end, the corresponding media source is the live broadcast source, the media information playback request is the live broadcast information playback request, and the media information to be played is the live broadcast information to be played.

[0054] S202: Select a target gateway from the gateway pool according to the total usage of the gateway pool.

[0055] In one embodiment, the total utilization rate may be the ratio of the number of used gateways in the gateway pool to the total number of gateways in the gateway pool; in one embodiment, the total utilization rate changes dynamically over time. The target gateway may be the optimal gateway dynamically selected from the gateway pool of the media source.

[0056] Furthermore, since the target gateway is dynamically selected from the gateway pool as the total utilization rate changes, it is necessary to select the optimal gateway as the target gateway based on the dynamic changes in the total utilization rate to ensure the optimization of the target gateway. In one embodiment, when the total utilization rate of the gateway pool is less than or equal to a first threshold, the gateway in the gateway pool closest to the media demand end is selected as the target gateway; when the total utilization rate is greater than the first threshold and the total utilization rate is less than a second threshold, the target gateway is selected from the gateway pool based on the indicator value of each gateway in the gateway pool under the communication indicator; wherein the second threshold is greater than the first threshold.

[0057] For example, the first and second thresholds are preset to be 25% and 50% respectively. When the total utilization rate of the gateway pool is less than or equal to 25%, the distance between each gateway in the gateway pool and the media demand end is determined, and the gateway in the gateway pool with the smallest distance to the media demand end is selected as the target gateway. When the total utilization rate of the gateway pool is greater than 25% and less than 50%, it is necessary to combine the comprehensive index values ​​of each gateway in the gateway pool under various communication indicators and select the gateway with the best comprehensive index value from the gateway pool as the target gateway.

[0058] Furthermore, when the total usage rate of the gateway pool is greater than 50%, the target gateway selection is not performed, and the media information acquisition method is restarted.

[0059] S203: Feedback the gateway information of the target gateway to the media demand side.

[0060] The gateway information may be identification information of the gateway, which is used to accurately locate the gateway. In the embodiment of the present application, the gateway information is used by the media demand end to locate the target gateway, so as to obtain the media information to be played through the target gateway.

[0061] Specifically, after determining the target gateway, the gateway information of the target gateway is sent to the media demand end, and the media demand end locates the target gateway according to the gateway information, and obtains the to-be-played media information of the media source through the target gateway for playback.

[0062] In the above-mentioned media information acquisition method, by responding to a media information playback request sent by a media demand side, a gateway pool of the media source corresponding to the media information to be played is obtained, and a target gateway is selected from the gateway pool based on the total usage rate of the gateway pool. Then, the gateway information of the target gateway is fed back to the media demand side, so that the media demand side can locate the target gateway and obtain the media information to be played through the target gateway. In the media information acquisition method of the present application, the target gateway is dynamically selected from the gateway pool based on the changing indicator of the total usage rate of the gateway pool, which can always schedule the playback of media to the optimal gateway, thereby always providing users with a high-level playback experience.

[0063] Based on the above embodiment, the steps of selecting a target gateway from the gateway pool are decomposed and refined through Figure 3. In one embodiment, as shown in Figure 3, the following implementation process is included:

[0064] S301 , performing weighted calculation on the indicator value of each gateway in the gateway pool under the communication indicator according to the weight of the communication indicator, to obtain the weighted value of each gateway in the gateway pool.

[0065] In one embodiment, when the medium is live broadcast, the communication indicator in the embodiment of the present application includes at least one of latency, bandwidth consumption, computing power consumption, packet loss, and multicast multiplexing rate. The communication indicator in the embodiment of the present application can also be other indicators, such as bit rate, time division multiplexing rate, code division multiplexing rate, etc. The embodiment of the present application does not limit the type of communication indicator.

[0066] Furthermore, the latency represents the average response time of each media demand end to the media information when the gateway obtains the media information for each media demand end. Packet loss represents the average packet loss rate of each media demand end when the gateway obtains the media information for the media demand end, such as UDP (User Datagram Protocol) packet loss. Bandwidth consumption represents the bandwidth consumed by the media source, including southbound bandwidth (i.e., total unicast stream bandwidth) and northbound bandwidth (i.e., multicast stream bandwidth); due to the different locations of gateway deployment, the closer to the media demand end, the smaller its bandwidth consumption; in order to reduce the computational complexity of bandwidth consumption, gateways are divided into three categories: backbone core gateways, metropolitan area aggregation gateways, and edge gateways; when calculating bandwidth consumption, it is necessary to multiply the actual bandwidth consumption by coefficients of 1, 0.6, and 0.4, respectively, to obtain the bandwidth consumption of the three types of gateways. Computing power consumption represents the computing power consumed by the media source. To simplify the computing power model, this application only calculates the computing power consumption of the CPU (Central Processing Unit). The multicast multiplexing rate represents the inverse of the number of media demand ends that obtain the same media information on the gateway.

[0067] Specifically, for each gateway in the gateway pool, the gateway's weight for each communication indicator and the indicator value of each communication indicator are weighted and summed to obtain the gateway's weighted value. This process is repeated to obtain the weighted value of each gateway in the gateway pool. For example, if a gateway includes three communication indicators, and the weights of the three communication indicators are 20%, 30%, and 50%, respectively, and the indicator values ​​of the three communication indicators are 1, 2, and 3, respectively, then the gateway's weighted value is 20% * 1 + 30% * 2 + 50% * 3 = 2.3.

[0068] S302: The gateway corresponding to the minimum weighted value in the gateway pool is used as the target gateway.

[0069] Specifically, after obtaining the weighted values ​​of the gateways in the gateway pool, the weighted values ​​of the gateways in the gateway pool are sorted, and then the gateway corresponding to the minimum weighted value is used as the target gateway.

[0070] It can be understood that this embodiment provides a method for determining the target gateway by solving the weighted values ​​of each gateway in the gateway pool and using the gateway corresponding to the minimum weighted value as the target gateway, thereby laying the foundation for the subsequent process of obtaining media information.

[0071] Based on the above embodiment, the steps of building a gateway pool are decomposed and refined through Figure 4. In one embodiment, as shown in Figure 4, the following implementation process is included:

[0072] S401: Select a backup gateway set from multiple optional gateways.

[0073] In one embodiment, because the coverage of the gateways included in the optional gateways may or may not cover the media source, in order to ensure that the coverage of the determined gateway covers the media source, it is necessary to select a gateway from the multiple optional gateways. Specifically, a first gateway covering the media source and a second gateway other than the first gateway are selected from the multiple optional gateways; a second preset number of third gateways are selected from the second gateways with the first gateway as the center; and the set of the first and third gateways is used as a backup gateway set. For example, two first gateways covering the media source are selected from the multiple optional gateways: first gateway 1 and first gateway 2; a second preset number of third gateways are selected from the second gateways other than the first gateway, each of which is centered on first gateway 1 and first gateway 2 and has a radius of a preset length; and the set of the first and third gateways is used as a backup gateway set. In one embodiment, the second preset number is a multiple of the number of first gateways.

[0074] It should be noted that the coverage of the selected third gateway also needs to cover the media source.

[0075] S402 : Select a first preset number of gateways from the backup gateway set according to the indicator value of each gateway in the backup gateway set under the communication indicator to build a gateway pool.

[0076] Specifically, after obtaining the backup gateway set, a first preset number of gateways are selected from the backup gateway set in combination with the Pareto optimal solution algorithm and QoS (Quality of Service) requirements to construct a gateway pool. The expressions of the Pareto optimal solution algorithm and QoS requirements are shown in the following equations (1) and (2), respectively: min F(X) = [f1(X), f2(X), f3(X), f4(X), f5(X)]; (1) f i (X) <= QoS i (X),i=1,2,3,4,5; (2) X={x1,x2,……,x n}; X∈Ω

[0077] Among them, f i (X) represents the indicator value of the gateway under the i-th communication indicator; the value of i ranges from 1 to 5, corresponding to latency, bandwidth consumption, computing power consumption, packet loss, and multicast multiplexing rate, respectively; X represents a set of Pareto optimal gateways that meet QoS requirements, x1, x2, ..., x n is an element in the Pareto optimal gateway set, representing any optimal gateway; Ω represents multiple optional gateways.

[0078] It should be noted that the gateway pool of the media source can be updated as needed. For example, when a gateway pool update event is detected, the constructed gateway pool is updated. The detection of a gateway pool update event can be the detection of high usage thresholds and low usage thresholds, gateway failure, low-quality alarms, etc. For example, when the high and low usage thresholds are detected, the total usage of the gateways in the constructed gateway pool is detected at preset time intervals. If the total usage of the gateways in the gateway pool is higher than the high usage threshold, the gateway pool is expanded and updated; if the total usage of the gateways in the gateway pool is lower than the low usage threshold, the gateway pool is reduced and updated.

[0079] It can be understood that this embodiment provides a possible way to build a gateway pool based on the Pareto optimal solution algorithm and QoS requirements, provides conditions for selecting a target gateway from the gateway pool, and lays the foundation for the subsequent process of obtaining media information.

[0080] In one embodiment, FIG5 shows a flow chart of a method for obtaining media information in another embodiment. In conjunction with FIG5 , each stage specifically includes the following implementation process:

[0081] S501, the live broadcast source sends a live broadcast notification to the scheduling server.

[0082] S502: The scheduling server builds a gateway pool for the live broadcast source.

[0083] S503, the live broadcast demand end sends a live broadcast information playback request to the scheduling server.

[0084] In one embodiment, the scheduling server obtains the gateway pool of the live broadcast source according to the live broadcast information carried in the live broadcast information playback request.

[0085] S504: The scheduling server determines a scheduling method according to a relationship between the total usage rate of the gateway pool and the first threshold, and selects a target gateway from the gateway pool using the scheduling method.

[0086] In one embodiment, when the total usage rate of the gateway pool is less than a first threshold, a proximity scheduling method is selected to select a target gateway from the gateway pool; when the total usage rate of the gateway pool is greater than the first threshold, a multi-target scheduling method is selected to select a target gateway from the gateway pool.

[0087] S505: The scheduling server feeds back the gateway information of the target gateway to the media demand side.

[0088] In one embodiment, the gateway information is used by the media demand side to locate the target gateway, so as to obtain the to-be-played media information through the target gateway.

[0089] S506: The media demand end obtains the to-be-played media information from the target gateway based on the gateway information and plays the media.

[0090] The specific process of the above S501-S506 can be found in the description of the above method embodiment. The implementation principles and technical effects are similar and will not be repeated here.

[0091] In one embodiment, FIG6 shows a structural block diagram of a scheduling server in one embodiment. As shown in FIG6 , the scheduling server includes a playback scheduling server 601 and a dynamic gateway scheduling server 602 .

[0092] In one embodiment, it is executed by the dynamic gateway scheduling server 602.

[0093] Furthermore, the playback scheduling server 601 and the dynamic gateway scheduling server 602 are interconnected via interfaces 1 and 2. A media demander sends a media playback request to the playback scheduling server 601, which forwards it to the dynamic gateway scheduling server 602. The dynamic gateway scheduling server 602 retrieves the gateway pool of the media source corresponding to the media information to be played, selects a target gateway from the gateway pool based on the total usage rate of the gateway pool, and sends the gateway information of the target gateway to the playback scheduling server 601. The playback scheduling server 601 then sends the gateway information to the media demander. The media demander can then retrieve the media information to be played based on the gateway information.

[0094] It should be understood that, although the various steps in the flowcharts involved in the various embodiments described above are displayed in sequence according to the instructions of the arrows, these steps are not necessarily executed in sequence in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and these steps can be executed in other orders. Moreover, at least a portion of the steps in the flowcharts involved in the various embodiments described above can include multiple steps or multiple stages, and these steps or stages are not necessarily executed and completed at the same time, but can be executed at different times, and the execution order of these steps or stages is not necessarily to be carried out in sequence, but can be executed in turn or alternately with other steps or at least a portion of steps or stages in other steps.

The solution provided by this device is similar to the solution described in the aforementioned method. Therefore, the specific limitations of one or more embodiments of the media information acquisition device provided below can be found in the aforementioned limitations of the media information acquisition method and will not be further elaborated here.
