Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0023] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in an order other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0024] Optionally, as an optional implementation, as Figure 1 As shown, the method for distributing media resources includes the following specific steps:

[0025] S102, determining a target transmission speed of the initial media resource to be distributed according to the communication bandwidth information of the playback end;

[0026] S104, determining a target transmission period of the initial media resource according to the target transmission speed and the historical transmission speed of the historical media resource;

[0027] S106, determining a slice size of a single media resource based on a target transmission speed and a target transmission period;

[0028] S108, dividing the initial media resource into a plurality of target media resources according to the fragment size, wherein the fragment size of each target media resource is the fragment size;

[0029] S110, creating index information for multiple target media resources, and distributing the index information and the multiple target media resources to an edge server, wherein the edge server is used to respond to a media resource acquisition request from a playback terminal.

[0030] Optionally, in this embodiment, the method for distributing media resources can be applied to, but not limited to, a media file transmission scenario based on HLS (HTTP Live Streaming, HLS for short) fragmentation. In this scenario, the media file is divided into a series of small fragments (chunks), each of which usually lasts for a few seconds. These fragments can be dynamically loaded and played to adapt to different network conditions and devices.

[0031] It should be noted that in the related art, the size of media resource shards is mostly preset or random. For edge nodes with small bandwidth or high network fluctuation frequency, if the shard size is large, packet loss will easily occur, thereby affecting the use effect and resulting in poor distribution of media resources.

[0032] In response to the above problem, this embodiment determines the target transmission speed of the initial media resource based on the communication bandwidth information of the playback end, and then determines the target transmission period of the initial media resource based on the target transmission speed of the initial media resource and the historical transmission speed of the historical media resource. In this way, the fragment size of a single media resource is determined based on the product of the target transmission speed and the target transmission period, and the initial media resource is divided based on the fragment size to obtain multiple target media resources, which are distributed to the edge server after establishing index information, thereby ensuring network stability during media resource distribution and preventing edge nodes with small bandwidth or high network fluctuation frequency from packet loss if the fragment size is large, thereby achieving the technical effect of improving the distribution effect of media resources and solving the problem of poor distribution effect of the above-mentioned media resources.

[0033] Optionally, in this embodiment, the target transmission speed of the initial media resource to be distributed is determined based on the communication bandwidth information of the playback end, which may include but is not limited to determining the first playback end with the smallest communication bandwidth from all playback ends; and determining the target transmission speed based on the communication bandwidth of the first playback end.

[0034] Optionally, in this embodiment, the target transmission speed of the initial media resource to be distributed is determined based on the communication bandwidth information of the playback end, and it may also include but is not limited to determining a second playback end whose communication bandwidth meets the expected bandwidth condition from all playback ends; and determining the target transmission speed based on the average communication bandwidth of the second playback end.

[0035] It can be understood that the second playback end can be but is not limited to multiple playback ends that meet the expected bandwidth conditions, wherein the expected bandwidth conditions can be but are not limited to the communication bandwidth being greater than the first preset threshold, can also be but are not limited to the communication bandwidth being less than the second preset threshold, can also be but are not limited to being greater than the first preset threshold and less than the third preset threshold.

[0036] It should be noted that the transmission speed can be determined based on the communication bandwidth of the playback end, and can be calculated by, but not limited to, the following formula:

[0037] Transmission speed = communication bandwidth / 8

[0038] The unit of communication bandwidth is usually bits per second (bps), and the unit of transmission speed is usually bytes per second (Bps). Therefore, when calculating the transmission speed, the unit of communication bandwidth is converted to bytes per second. The specific conversion method is to divide the communication bandwidth by 8 to get the corresponding transmission speed.

[0039] Optionally, in this embodiment, the historical transmission speed of the historical media resource may be, but is not limited to, an average value of N transmission speeds corresponding to N previous media resource distributions occurring within a historical time period.

[0040] Optionally, in this embodiment, the target transmission period of the initial media resource is determined based on the target transmission speed and the historical transmission speed of the historical media resources, which may include, but is not limited to, determining the minimum time difference when the transmission speed is less than the target transmission speed for each media resource distribution process in the above-mentioned N media resource distributions in turn; and performing weighted summation of the minimum time differences for the N media resource distributions based on the weight coefficient and the minimum time difference corresponding to each media resource distribution process to obtain the target transmission period.

[0041] Optionally, in this embodiment, based on the weight coefficient and minimum time difference corresponding to each media resource distribution process, a weighted summation of the minimum time differences is performed on N media resource distributions to obtain a target transmission period, which may include but is not limited to: obtaining the i-th weight coefficient and the i-th minimum time difference corresponding to the i-th media resource distribution process, wherein the i-th weight coefficient is the accumulation of i+1 weight values, the m-th weight value among the i weight values ​​is the m-1th power of a preset parameter, i is a positive integer less than or equal to N, and m is a natural number less than i; determining the product of the i-th weight coefficient and the i-th minimum time difference as the weighted product result corresponding to the i-th media resource distribution process; adding the weighted product results corresponding to each media resource distribution process in the N media resource distributions, and dividing by N to obtain the target transmission period.

[0042] Optionally, in this embodiment, determining the slice size of a single media resource based on the target transmission speed and the target transmission period may include, but is not limited to: determining the slice size of a single media resource based on the product of the target transmission speed and the target transmission period.

[0043] Optionally, in this embodiment, the fragment size of a single media resource is determined based on the product of the target transmission speed and the target transmission period, which may include but is not limited to: using 1 minus the value of the redundancy coefficient, multiplying it by the product of the target transmission speed and the target transmission period to obtain the fragment size of the single media resource.

[0044] It should be noted that the initial media resource is divided into a plurality of target media resources according to the fragment size, wherein the segment size of each target media resource is the fragment size.

[0045] Optionally, in this embodiment, index information is created for multiple target media resources, which may be, but is not limited to, used to instruct generation of m3u8 index files for the multiple target media resources.

[0046] It can be understood that the index information and multiple target media resources are distributed to the edge server, wherein the edge server is used to respond to the media resource acquisition request of the playback end.

[0047] Through the embodiments provided by the present application, the target transmission speed of the initial media resource is determined according to the communication bandwidth information of the playback end, and then the target transmission period of the initial media resource is determined according to the target transmission speed of the initial media resource and the historical transmission speed of the historical media resource. In this way, the fragment size of a single media resource is determined based on the product of the target transmission speed and the target transmission period, and the initial media resource is divided based on the fragment size to obtain multiple target media resources, which are distributed to the edge server after the index information is established, thereby ensuring the network stability during the distribution of media resources and preventing the edge nodes with small bandwidth or high network fluctuation frequency from packet loss if the fragment size is large, thereby improving the distribution effect of media resources.

[0048] As an optional solution, according to the target transmission speed and the historical transmission speed of the historical media resources, the target transmission period of the initial media resources is determined, including:

[0049] Obtain N transmission speeds corresponding to N media resource distributions occurring in a historical time period, and determine an average value of the N transmission speeds as a historical transmission speed, where N is a positive integer;

[0050] For each media resource distribution process in the N media resource distributions, determine the minimum time difference at which the transmission speed is less than the target transmission speed;

[0051] Based on the weight coefficient and the minimum time difference corresponding to each media resource distribution process, the minimum time difference of N media resource distributions is weightedly summed to obtain the target transmission period.

[0052] Optionally, in this embodiment, according to the transmission speed of the previous N media resource distribution processes, two transmission time nodes whose transmission speed is less than the target transmission speed are determined, and the time interval Δt between adjacent time nodes is calculated, and then the minimum value is taken to obtain Δt imin , represents the minimum time difference between two adjacent transmission speeds that are less than the target transmission speed in the current transmission speed.

[0053] Optionally, in this embodiment, according to The target transmission period t is calculated, where n is the number of media resource distributions that occurred in the historical time period, and k is the number of media resource distributions that occurred in the historical time period. i is the weight coefficient, which satisfies k i =a i-m +a i-m-1 +……+a i -1 , where a is a constant greater than 1, and m is a natural number less than i.

[0054] Through the embodiments provided by the present application, the fragment size is determined based on the target transmission speed and the target transmission period, thereby ensuring network stability during the transmission of media resources and preventing packet loss. The calculation of the target transmission period adopts the control method of the time node in combination with the weight, and the weight can be determined based on the fluctuation of the adjacent time, so that the result is more accurate.

[0055] As an optional solution, based on the weight coefficient and the minimum time difference corresponding to each media resource distribution process, the minimum time difference of N media resource distributions is weighted and summed to obtain the target transmission period, including:

[0056] Obtain the i-th weight coefficient and the i-th minimum time difference corresponding to the i-th media resource distribution process, wherein the i-th weight coefficient is the accumulation of i+1 weight values, the m-th weight value among the i+1 weight values ​​is the m-1th power of a preset parameter, i is a positive integer less than or equal to N, and m is a natural number less than i;

[0057] Determine the product of the i-th weight coefficient and the i-th minimum time difference as the weighted product result corresponding to the i-th media resource distribution process;

[0058] The weighted product results corresponding to each media resource distribution process in the N media resource distributions are added together and divided by N to obtain the target transmission period.

[0059] Optionally, in this embodiment, the i-th weight coefficient corresponding to the i-th media resource distribution process is the accumulation of i+1 weight values, and the m-th weight value among the i weight values ​​is the m-1th power of a preset parameter, where i is a positive integer less than or equal to N, and m is a natural number less than i.

[0060] Optionally, in this embodiment, the product of the i-th weight coefficient and the i-th minimum time difference is determined as the weighted product result corresponding to the i-th media resource distribution process; the weighted product results corresponding to each media resource distribution process in N media resource distributions are added and divided by N to obtain the target transmission period.

[0061] Through the embodiments provided in the present application, the target transmission period is calculated by using a time node control method in combination with weights, and the weights can be determined based on fluctuations in the adjacent time periods, thereby making the results more accurate.

[0062] As an optional solution, the target transmission speed of the initial media resource to be distributed is determined according to the communication bandwidth information of the playback end, including:

[0063] Determine a first playback terminal with the smallest communication bandwidth from all playback terminals;

[0064] Determine the target transmission speed according to the communication bandwidth of the first playback end; or,

[0065] Determine a second playback terminal whose communication bandwidth meets the expected bandwidth condition from all playback terminals;

[0066] The target transmission speed is determined according to the average communication bandwidth of the second playback end.

[0067] Optionally, in this embodiment, the second playback end may be, but is not limited to, multiple playback ends that meet the expected bandwidth condition, wherein the expected bandwidth condition may be, but is not limited to, the communication bandwidth being greater than a first preset threshold, may be, but is not limited to, the communication bandwidth being less than a second preset threshold, may be, but is not limited to, being greater than the first preset threshold and less than a third preset threshold.

[0068] It should be noted that the transmission speed can be determined based on the communication bandwidth of the playback end, and can be calculated by, but not limited to, the following formula:

[0069] Transmission speed = communication bandwidth / 8

[0070] The unit of communication bandwidth is usually bits per second (bps), and the unit of transmission speed is usually bytes per second (Bps). Therefore, when calculating the transmission speed, the unit of communication bandwidth is converted to bytes per second. The specific conversion method is to divide the communication bandwidth by 8 to get the corresponding transmission speed.

[0071] Optionally, as an optional implementation, as Figure 2 As shown, the method for storing media resources includes the following specific steps:

[0072] Receiving multiple target media resources and multiple index information corresponding to the multiple target media resources;

[0073] storing the plurality of target media resources and the plurality of index information in a first cache area;

[0074] Determine, from the plurality of target media resources and the plurality of index information, a popular target media resource that meets the expected media resource condition and popular index information corresponding to the popular target media resource, wherein the expected media resource condition is used to indicate that the frequency at which the target media resource is requested by the playback terminal within a preset time period is greater than a preset frequency threshold;

[0075] After a preset time period, the popular target media resources and popular index information are stored in the second cache area, and other target media resources and other index information except the popular target media resources and popular index information among the multiple target media resources and multiple index information are deleted from the first cache area.

[0076] Optionally, in this embodiment, the storage method of media resources can be applied to, but not limited to, a media file transmission scenario based on HLS (HTTP Live Streaming, HLS for short) fragmentation. In this scenario, the media file is divided into a series of small fragments (chunks), each of which usually lasts for a few seconds. These fragments can be dynamically loaded and played to adapt to different network conditions and devices.

[0077] Optionally, in this embodiment, multiple target media resources and multiple index information corresponding to the multiple target media resources can be, but are not limited to, obtained by dividing the initial media resources to be distributed by the central (control) server according to the fragment size of a single media resource, the fragment size of each target media resource is the above-mentioned fragment size, and each target media resource corresponds to one index information.

[0078] Optionally, in this embodiment, the central (control) server divides the initial media resources to be distributed according to the fragment size of a single media resource to obtain multiple target media resources and multiple index information, which can be achieved but is not limited to the above-mentioned media resource distribution method, which will not be repeated here.

[0079] Optionally, in this embodiment, the edge server may, but is not limited to, include a first cache area and a second cache area, wherein the first cache area is used for short-term caching (caching objects for at most a first time period), and the second cache area is used for long-term caching (caching objects for at most a second time period, the second time period being longer than the first time period).

[0080] Optionally, in this embodiment, the edge server initially caches the received multiple target media resources and multiple index information in a first cache area. Within a preset time period, if the frequency of being requested by the playback end is greater than a preset frequency threshold, the target media resource is determined to be a popular media resource, and the popular media resource and its corresponding popular index information are cached in a second cache area to reduce subsequent repeated requests and transmission delays.

[0081] Optionally, in this embodiment, other target media resources and other index information except popular target media resources and popular index information among the multiple target media resources and multiple index information are deleted from the first cache area to reduce storage pressure on the edge server.

[0082] The embodiment provided in the present application is improved, and target media resources whose frequency of being requested by the playback end is greater than a preset frequency threshold within a preset time period are cached in a second cache area for a long time, and other target media resources are deleted after the preset time period, which not only reduces subsequent repeated requests and transmission delays, but also reduces storage pressure.

[0083] As an optional solution, after playing the target media resource, the method further includes:

[0084] In response to a first media resource acquisition request requested by the first playback end, acquiring a first target media resource corresponding to the first index information from a cache area, wherein the first media resource acquisition request is used to request to acquire the first target media resource, and the cache area includes a first cache area and a second cache area;

[0085] If the first index information does not exist in the cache area, forward the first media resource acquisition request to other edge servers;

[0086] Obtain the first target media resource from other edge servers.

[0087] Optionally, in this embodiment, in response to the first media resource acquisition request requested by the first playback end, the first target media resource corresponding to the first index information is acquired from the cache area.

[0088] It should be noted that, when the first index information does not exist in the cache area, the first media resource acquisition request is forwarded to other edge servers, and the other edge servers respond to the request and acquire the first target media resource.

[0089] It is understandable that, for the playback end, after receiving the m3u8 index file, it first attempts to obtain media resources from the nearest edge server. If the edge server does not have the required media resources, or cannot respond in time due to network congestion and other reasons, the playback end will initiate a request to other edge servers (such as adjacent or nearest edge servers).

[0090] Through the embodiments provided by the present application, when the required media resources do not exist on the current edge server, the request is forwarded, thereby improving the efficiency and flexibility of the transmission of media resources.

[0091] As an optional solution, the above media resource distribution method is applied to a video transmission system based on HLS segmentation, such as Figure 3 As shown, the video transmission system includes a video source server 302, a central control server 304, an edge node 306, and a playback terminal 308. The video source server 302 is responsible for collecting and encoding the original video data and transmitting it to the central control server 304. The central control server 304 is responsible for the distribution of video streams, node management, data synchronization, and network status monitoring. The edge node 306, a node located at the edge of the network, has a large bandwidth and storage capacity, is responsible for caching and forwarding video data, and reduces the burden of the central control server. The playback terminal 308 is used to receive and play video data.

[0092] Optionally, in Figure 3 In the video transmission system shown, the central control server 304 adopts a data transmission mechanism based on the HLS protocol to divide the video stream into multiple TS file segments, and generates an m3u8 index file, which is distributed to the edge node 306. The playback end 308 downloads the file segments from the edge node 306 in sequence according to the m3u8 index file for playback.

[0093] Optionally, the video segmentation and indexing process performed by the central control server 304 is as follows: Figure 4 As shown, the specific steps include:

[0094] S402, after establishing the communication connection, obtaining the communication bandwidth of each playback end, and calculating the corresponding transmission speed V according to the communication bandwidth of each playback end;

[0095] S404, obtaining an adaptive stable transmission period t according to the previous transmission speed;

[0096] S406, setting a redundancy coefficient Δ, and then calculating the size of a single TS file segment according to the formula P=(1-Δ)Vt;

[0097] S408, dividing the file into a plurality of file segments of P size.

[0098] Optionally, in the above step S404, the process of determining the stable transmission period t includes the following specific steps: Figure 5 As shown, including:

[0099] S502, obtaining the transmission speeds of the previous n times by monitoring the previous transmission speeds;

[0100] S504: Determine two transmission time nodes whose transmission speed is less than V according to the transmission speeds of the previous n times, calculate the time interval Δt between adjacent time nodes, and then take the minimum value to obtain Δt imin , which represents the minimum time difference between two adjacent transmission speeds less than V in the previous i-th transmission speed;

[0101] S506, according to Calculate the adaptive stable transmission period t,k i is the weight coefficient, which satisfies k i =a i-m +a i-m-1 +……+a i-1 , where a is a constant greater than 1, and m is a natural number less than i.

[0102] Optionally, in Figure 3 In the video transmission system shown, for the player 308, after receiving the m3u8 index file, first try to obtain the TS file segment from the nearest edge node. If the edge node does not have the required TS file segment, or cannot respond in time due to network congestion and other reasons, the player will initiate a request to other players.

[0103] Optionally, the playback terminal 308 has a built-in verification unit. The working logic of the verification unit includes: according to the m3u8 index file, the index identifier of the multiple files connected is confirmed; the index identifier of the current playback segment is obtained, and the local cache is checked to see if there is an index identifier of the next playback segment; if not, the file segment with the corresponding index identifier is obtained from other edge nodes.

[0104] Through the embodiments provided by the present application, the shard size can be determined based on the node bandwidth and the frequency of past network fluctuations, thereby ensuring the stability of the network during transmission and preventing packet loss. In addition, the calculation of the fluctuation frequency adopts the control method of the time node in combination with the weight, and the weight can be determined based on the fluctuation of the adjacent time, so that the result is more accurate.

Secondly, those skilled in the art should also be aware that the embodiments described in the specification are all preferred embodiments, and the actions and modules involved are not necessarily required by the present application.

[0107] Optionally, as an optional implementation, as Figure 6 As shown, the media resource distribution device includes:

[0108] A first determining unit 602 is used to determine a target transmission speed of an initial media resource to be distributed according to the communication bandwidth information of the playback end;
