As shown in fig. 1, a flow chart of a processing method of audio and video data according to an aspect of the present application is provided, and the method is applied to a content distribution network, and the method includes steps S11, S12 and S13, and specifically includes the following steps:
step S11, receiving a target audio/video acquisition request initiated by a user; here, the acquiring request may be initiated by the user in response to an acquiring operation of the target audio and video, where the acquiring operation of the target audio and video may include, but is not limited to, a triggering operation of the target audio and video, and a voice operation, where the triggering operation includes, but is not limited to, an operation of touching, a gesture, a fingerprint, and the like, and the voice operation includes, but is not limited to, an operation of performing voice acquisition by a user voice control or by a third party voice control, and the like.
Step S12, determining the target audio/video file corresponding to the acquisition request and/or the heat information of at least two target audio/video slicing files in the target audio/video file. The content distribution network can acquire and count the number of url requests initiated by a user aiming at a target audio and video file or the number of url requests initiated by the same target audio and video file and split into different fragment files to determine the heat information of the requests.
Step S13, a call interface is provided for a CDN service provider or an audio/video content provider or a third party, so that the CDN service provider or the audio/video content provider or the third party can obtain the heat information, and process a target audio/video file and/or at least two target audio/video fragment files in the target audio/video file based on the heat information. The processing may be utilized by the CDN service provider or the audio/video content provider or a third party based on the acquired heat information, and processed in a specific application scenario to improve user experience or improve commercial value, so as to provide more possibilities for service expansion of each party, for example, the CDN service provider may perform pre-caching processing or preferential response processing based on the acquired heat information, the audio/video service provider may perform highlight production processing, thermodynamic diagram drawing processing, advertisement inserting processing based on the acquired heat information, or the third party may put in commercial advertisement processing.
Herein, the third party includes, but is not limited to, a partner or a federation of content delivery network CDN customers, etc., such as an advertisement dispenser, an industry analysis agency, etc.
Through the steps S13 to S13, a call interface is provided for a CDN service provider or an audio/video content provider or a third party through a content delivery network, so that the CDN service provider or the audio/video content provider or the third party can obtain the heat information, and pre-cache, preferentially respond, highlight gathering, thermodynamic diagram drawing, advertisement inserting and the like are performed on a target audio/video file and/or at least two target audio/video fragment files in the target audio/video file based on the obtained heat information, so that the audio/video content provider can timely know the cold and hot conditions of the target audio/video file and the target audio/video fragment files therein, and caching efficiency, video watching experience, advertisement exposure and the like of a user can also be improved.
For example, when the user wants to know the hot condition of the target audio/video or what piece of information is the hot audio/video, the user can perform an acquisition operation on the target audio/video, so that the user initiates an acquisition request to the content distribution network in response to the acquisition operation on the target audio/video; after receiving an acquisition request of a user for a target audio/video, the content distribution network determines the heat information of the target audio/video file corresponding to the acquisition request and/or at least two target audio/video fragment files in the target audio/video file so as to ensure that the determined heat information of the target audio/video file not only can reflect the overall heat but also can reflect the heat information of the target audio/video fragment files of each fragment in the target audio/video file, thereby realizing the heat condition of the target audio/video from two aspects of overall and fragment; and finally, a call interface can be provided for a CDN service provider or an audio/video content provider or a third party, so that the CDN service provider or the audio/video content provider or the third party can conveniently acquire the heat information, and the target audio/video file and/or at least two target audio/video fragment files in the target audio/video file are matched with pre-caching, preferential response, highlight gathering, thermodynamic diagram drawing, advertisement inserting and other actual application scenes for processing the audio/video data based on the heat information, so that the audio/video content provider can timely know the cold and hot conditions of the target audio/video file and the target audio/video fragment files in the target audio/video file, and the caching efficiency, the watching experience of a user, advertisement exposure and the like can be further improved.
Following the above embodiment of the present application, the calling interface in step S13 includes, but is not limited to, any form of an application programming interface, a report, and a front end interface. For example, in step S13, the content delivery network may feed the target audio/video file and/or the heat information of at least two target audio/video slicing files in the target audio/video file back to the client of the content delivery network CDN, that is, the audio/video website or the audio/video content provider such as the application, or feed the information back to the CDN service provider, or feed the information back to a third party, etc., through an API mode, a report, a front-end interface, etc., so as to implement different calling forms of the heat information of the target audio/video file and/or at least two target audio/video slicing files in the target audio/video file, thereby meeting different calling requirements.
Next, in the above embodiment of the present application, the step S12 of determining the heat information of the target audio/video file corresponding to the acquisition request and/or at least two target audio/video clips in the target audio/video file specifically includes:
counting the historical acquisition request number of the target audio and video file according to the acquisition request, and determining the heat value of the target audio and video file;
And/or determining a heat value and parameter information corresponding to each target audio/video slicing file in the target audio/video according to the historical request number of the target audio/video file and the historical request number of each target audio/video slicing file in the target audio/video file.
Here, the heat value includes, but is not limited to, a request frequency reflecting the target audio/video, etc.; the parameter information includes, but is not limited to, one or more of a time of the target audio/video clip file in the target audio/video file, a person related to the target audio/video clip file, a bullet screen of comments made by a user on the target audio/video clip file, and an object related to the target audio/video clip file, so as to reflect parameter information of each target audio/video clip file in the target audio/video file. For example, when a viewer watches a video through a client, a request is sent to a CDN edge cloud platform, the platform counts the number of requests of different URLs and the number of requests of different fragments of the same URL, and obtains a real-time hotness list of the different URLs, a hot spot schedule corresponding to different fragments under the same URL and the like, so as to determine the target audio/video file and the hotness information of each target audio/video fragment file in the target audio/video file.
In an actual application scenario, when a user needs to know that the overall trending situation of a target audio/video can be reflected, statistics needs to be performed on the historical acquisition request number of the target audio/video file corresponding to the acquisition request according to the acquisition request, so that the trending situation of the URL carrying the target audio/video file can be reflected integrally, such as request frequency and the like, by accurately calculating the trending value of the target audio/video file. When a user needs to know the hot condition of each segmented audio/video in the target audio/video, the historical request number of the whole target audio/video files and the historical request number of each target audio/video segmented file in the target audio/video files are combined, the corresponding hot value and parameter information of each target audio/video segmented file are comprehensively calculated and determined, for example, the request frequency of each segmented target audio/video segmented file and the like can be reflected locally under the request frequency of the whole target audio/video, the segmented hot degree of the URL of each target audio/video file can be reflected, and therefore the hot degree of each target audio/video segmented file can be determined from the local angle, and meanwhile, the time of each target audio/video segmented file in the target audio/video file, the characters related to the target audio/video segmented file, the comments and the like performed by the user on the target audio/video segmented file, the related objects and the like can be determined, so that the parameter information of each target audio/video segmented file in the target audio/video file can be reflected more comprehensively.
Next, in the above embodiment of the present application, the step S12 of determining the heat information of at least two target audio/video clips in the target audio/video files corresponding to the obtaining request specifically includes:
receiving a corresponding first heat value set for each target audio/video slicing file in the target audio/video files respectively;
determining a heat value and parameter information corresponding to each target audio/video slicing file in the target audio/video slicing files based on a first heat value of each target audio/video slicing file and an original second heat value of each target audio/video slicing file; here, the parameter information includes, but is not limited to, one or more of a time of the target audio/video clip file in the target audio/video file, a character related to the target audio/video clip file, a comment and an insight made by a user on the target audio/video clip file, and an article related to the target audio/video clip file, so as to reflect parameter information of each target audio/video clip file in the target audio/video file.
Here, the first popularity value of each target audio/video slicing file in the target audio/video files is set according to the user requirement or the content distribution network user definition, for example, the popularity of the beginning stage in a novel can be improved, or more users are required to be attracted at the final ending of the television play to improve the play quantity of the television play, and the popularity of the ending of the television play can be set higher to meet the requirement of the popularity of different audio/video slicing; the original second popularity value of the target audio-video slicing file is used for indicating that when the actual request number of a user in an actual application scene is not acquired in an audio-video content provider of the target audio-video file such as an audio-video website or an application, the popularity of the target audio-video slicing file relative to the target audio-video file, for example, the popularity of a television play, for example, a novel or a climax in a story, and the popularity of the target audio-video slicing file relative to the beginning, development and ending of a novel or the story, for example, the popularity of the novel or the climax in a story, and the like, when the user request is acquired, the original second popularity value of the target audio-video file is set, so that the final popularity value and parameter information of the target audio-video file are determined based on the first popularity value and the original second popularity value, and are transmitted to the content distribution network for consumption.
For example, when calculating and determining to obtain the heat information of at least two target audio/video slicing files in the target audio/video files corresponding to the request, the method can firstly receive a first heat value hot1 which is customized for each target audio/video slicing file in the target audio/video files according to the user requirement or the content distribution network, then combine the second heat value hot2 which is obtained from a provider (such as an audio/video website or an application) providing the audio/video content of the target audio/video files and is original for each target audio/video slicing file in the target audio/video files, and calculate and determine the first heat value hot1 which is set for each target audio/video slicing file in the target audio/video files, so that the accuracy of the calculation of the heat value of each target audio/video slicing file is improved by combining the set first heat value and the original second heat value, the method can more fully meet the requirement of a user in practical application, and more comprehensively reflect the accuracy of the target audio/video slicing files in the target audio/video files, and the related information of the target audio/video files in the target audio/video files is more comprehensively reflected, and the related to the target audio/video files in the target audio/video files is improved.
Next to the above-mentioned embodiment of the present application, a processing method of audio/video data according to an embodiment of an aspect of the present application further includes:
when a call interface is provided for the CDN service provider to retrieve the hotness information,
and determining one or more hot audio/video or hot audio/video fragments from the target audio/video file or at least two target audio/video fragment files in the target audio/video file based on the heat information corresponding to the target audio/video file or at least two target audio/video fragment files in the target audio/video file, and pre-caching the hot audio/video or the hot audio/video fragments.
In an actual application scenario, in order to meet the acquisition efficiency of users on audio/video files or audio/video files with different popularity levels in the target audio/video files, when a call interface is provided for a CDN service provider to acquire the popularity information, one or more hot audio/video files or one or more hot audio/video fragments can be screened out from the target audio/video files or at least two target audio/video fragment files in the target audio/video files, according to the popularity information corresponding to at least two target audio/video fragment files in the target audio/video files, for example, the popularity information of URLs of the target audio/video files or the popularity information of target audio/video fragments corresponding to different fragments in URLs of the target audio/video files is received by an edge device of a content distribution network provided by the CDN service provider, so that the popularity information of the target audio/video files or the target audio/video fragments is not required to be cached by the user, and the audio/video fragments are not required to be cached, and the audio/or the audio/video fragments are not required to be cached.
Next to the above-mentioned embodiment of the present application, a processing method of audio/video data according to an embodiment of an aspect of the present application further includes:
when a call interface is provided for the CDN service provider to retrieve the hotness information,
and determining one or more hot audio/video or hot audio/video fragments from the target audio/video file or at least two target audio/video fragment files in the target audio/video file based on the heat information corresponding to the target audio/video file or at least two target audio/video fragment files in the target audio/video file, and responding preferentially to the hot audio/video or the hot audio/video fragments.
In an actual application scenario, in order to further improve the response speed of a user to an audio/video file or an audio/video file with different popularity of a target audio/video file, when a call interface is provided for a CDN service provider to obtain the popularity information, one or more hot audio/video files or hot audio/video fragments can be screened out, and a pre-response is performed on the hot audio/video file or the hot audio/video fragments, so that an edge server of a content network provided by the CDN service provider can respond to the hot audio/video file or the hot audio/video file with high priority when receiving the hot audio/video request or the hot audio/video request of the user, or the hot audio/video fragments corresponding to different fragments in the URL of the target audio/video file, and the hot audio/video file or the hot audio/video fragment request of the target audio/video file can be preferentially responded to the hot audio/video file, thereby improving the audio/video request of the hot audio/video request, and the hot audio/video request can be preferentially responded to the hot audio/video file, and the hot audio/video can be preferentially screened out.
In the embodiment of the application, the screened hot audio/video or the hot audio/video fragments are pre-cached or preferentially responded, so that the targeted and directional optimization treatment (such as preferential response, multi-region pre-caching, and the like) on the hot fragments is realized by combining the hot information of the target audio/video file and the hot information of the target audio/video fragment files of different fragments in the target audio/video file, the viewing experience of the hot fragments of the audience of the video website can be greatly improved, the response speed and the distribution efficiency of the hot fragments are optimized, the overall cache consumption of the cold fragments is reduced, and finally the competitiveness in CDN products and service industry is improved.
