Specifically, the embodiment of the present invention provides a video distribution method, which solves the problem in the prior art that distribution of ultra-high definition video services requires consumption of a large amount of bandwidth.
As shown in fig. 1, an embodiment of the present invention provides a video distribution method, which is applied to a mobile edge computing MEC node, and specifically includes the following steps:
optionally, the first video file is an ultra high definition video, a user sends a play request of the first video file to the MEC node through an operation on a terminal, the terminal is a device located near the MEC node, and the terminal may be a device having a play function of itself, such as a mobile phone and a television, or a device having a signal sending function and connected to the play device. And the terminal plays the video file after receiving the feedback of the MEC node by sending a playing request to the MEC node or plays the video file through a playing device connected with the MEC node.
further, step 12 may be implemented by, but is not limited to:
in a first mode, the playing request carries configuration information of a playing device, or when a terminal sends a playing request of a first video file to the MEC node, configuration information of the playing device is sent at the same time; taking the terminal as a mobile phone as an example, if a user intends to play a video file through the mobile phone, the playing request sent by the terminal to the MEC node should carry configuration information of the mobile phone; or, if the user intends to play the video file through the television connected with the mobile phone signal, the playing request sent by the terminal to the MEC node should carry the configuration information of the television. And after receiving the playing request, the MEC node analyzes the playing request to obtain the playing configuration information.
And in a second mode, the playing request carries an identification number (ID) of a playing device, an equipment list corresponding to the ID number is stored in the MEC node, and after receiving the playing request, the MEC node acquires configuration information of the playing device corresponding to the ID number from the equipment list.
The playing configuration information includes, but is not limited to, a screen size, a resolution, a memory size, an operating system, a format supporting encoding and decoding, and the like of the device.
the MEC node may set a codec, and after the play configuration information is determined, perform a coding/decoding operation on the first video file according to the content of the play configuration information to obtain a coded/decoded second video file. For example, if it is determined that the codec format supported by the playback device is an Audio Video coding Standard (AVS) according to the playback configuration information, the MEC node performs real-time codec of the AVS format on the first Video file, and obtains a second Video file that is the codec format supported by the playback device.
According to the embodiment, the playing configuration information is determined by using the obtained playing request, and the first video file is subjected to accurate encoding and decoding format matching according to the playing configuration information, so that the risk that the video content watched by the user is incompatible due to the single encoding and decoding format at the cloud end is avoided, and the video watching experience of the user is greatly improved.
And step 14, sending the second video file.
And the MEC node performs coding and decoding operations on the first video file to obtain a second video file, and then sends the second video file to a playing device for playing. In this embodiment, after the encoding and decoding operations on the first video file are completed, the second video file is directly sent to the playing device by the MEC node without being pushed by a Content Delivery Network (CDN) node in province and city, and a user applying for video playing plays at the client. According to the method, the coding and decoding operations of the first video file are integrated at the MEC node, so that the distribution delay of video content and the current situation that a CDN (content delivery network) needs to consume a large amount of bandwidth can be reduced.
It should be noted that, because the MEC node provides services required by telecommunication users nearby by using a wireless access network, the playing request of the first video file received by the MEC node should be sent to a user near the MEC node, and the MEC node sends the second video file after the codec operation to a playing device of the user near the MEC node for playing.
According to the embodiment of the invention, the coding and decoding technology of the video service is integrated at the MEC node, and a separate server is not required to be arranged for coding and decoding, so that broadband resources are saved, and meanwhile, the expenditure can be saved; the MEC node utilizes the playing configuration information to perform accurate coding and decoding format matching on the first video file, the risk that the video content watched by a user is incompatible due to the single coding and decoding format of the cloud is avoided, and the video watching experience of the user is greatly improved.
As shown in fig. 2, before the step 11, the method may further include:
and uploading the shot first video file to the MEC node through the base station by the user. Optionally, a first video file shot by a user is processed by an encoder and uploaded to a video live broadcast platform through a 5G base station and a core network, the video live broadcast platform transmits the first video file to the MEC node of the base station through a CDN node and the 5G core network, and the MEC node acquires the first video file.
Further, as shown in fig. 3, the step 22 may include:
further, the step of determining whether the first video file is a target video file according to the attribute information includes:
and when the size of the first video file is larger than a preset size, the coding and decoding field of the first video file is a preset code, and the length of the first video file is larger than a preset length, determining that the first video file is the target video file.
Taking the target video file as an ultra high definition video as an example, assuming that the size of the ultra high definition video is greater than 720P, the coding and decoding field of the ultra high definition video is h.264/h.265/AVS2, and the length of the ultra high definition video is greater than 30 seconds, the preset size is 720P, the preset code is h.264/h.265/AVS2, and the preset length is 30 seconds; as shown in fig. 4, first, the size information of the first video file is read, and it is determined whether the size of the first video file is larger than 720P, if not, exiting the process and entering a central media asset library, if the number is larger than 720P, continuing to read the coding and decoding field information of the first video file, judging whether the coding and decoding field is H.264/H.265/AVS2, if not, exiting the process and entering the central media asset library, if so, reading the length information of the first video file, judging whether the length is more than 30 seconds, if not more than 30 seconds, exiting the process and entering a central media asset library, if more than 30 seconds, and the first video file is considered as the ultra high definition video, namely the first video file is the target video file.
The purpose of judging whether the first video file generates the content UGC for the user is to determine whether the first video file is uploaded and cached, and whether the first video file is uploaded is determined after the first video file is determined to be the UGC, so that the whole scheme can effectively reduce frequent scheduling of stream pulling and stream pushing operations of the CDN node, effectively reduce the occupation rate of limited bandwidth resources, and improve the timeliness of opening the video content by the user.
Further, the step 223 may include:
2231, acquiring identification information of the first video file;
optionally, a video distribution management system is integrated on the MEC node, and after the MEC node acquires the first video file, the video distribution management system identifies identification information of the first video file. The identification information may be a string of characters consisting of a plurality of numbers, which identifies information of a user, an uploading device, and the like of the first video file.
2232, performing matching calculation on the first video file and a pre-stored application list according to the identification information;
the MEC node stores therein an application list corresponding to identification information of different video files, and as shown in fig. 5, the application list may include an identification information field, a user identification field, a device identification field, a storage level field, and a content category field. And judging whether the identification information is the UGC or not by performing matching calculation on the identification information of the first video file and the application list.
Taking the identification information of the first video file as 001 as an example, as can be seen from fig. 5, the content category corresponding to 001 is UGC, that is, the first video file is the UGC.
The embodiment needs to perform matching calculation on the first video file in the MEC node, and although the calculation amount is small, the calculation is performed by the application layer which sinks to the MEC node, so that a data base can be provided for subsequent operations such as encoding and decoding.
And step 23, storing the first video file when the first video file meets a preset condition.
And when the first video file is the target video file and the first video file is the UGC, if the first video file meets a preset condition, the first video file needs to be stored.
It should be noted that storing the first video file may be caching the first video file in the MEC node, or sending the first video file to a content production center for storage.
Further, the step 23 may include:
when the first video file meets a preset condition, judging whether the storage level of the first video file is greater than a preset storage level;
optionally, the storage level is determined according to the click rate of the first video file, that is, the higher the click rate of the first video file is, the higher the storage level is, that is, storage is preferentially performed. According to the embodiment, the click rate is used as the basis for determining the storage level of the video file, the limited computing capacity of the MEC node is not occupied, and a better scheduling mechanism is set for the limited storage resource.
If the storage level is larger than the preset storage level, caching the first video file, otherwise, sending the first video file to a content production center for storage.
The storage level of the first video file is determined according to the click rate of the first video file, the MEC node caches the video file larger than the preset storage level, and therefore when the MEC node obtains a playing request of the first video file, the video file subjected to encoding and decoding can be directly sent to playing equipment after encoding and decoding, timeliness of opening video content by a user is effectively improved, and user experience is improved.
If the storage level of the first video file is smaller than the preset storage level, it is indicated that the click rate of the first video file is low, the probability that a user requests playing is low, the MEC node does not cache the first video file, but sends the first video file to a content production center at the cloud end, the content production center can cache or store the first video file, further perform content adjustment on the first video file, such as adding a watermark, an advertisement and the like, after performing content adjustment on the first video file, the content production center sends the first video file to a CDN node through a central media asset, the CDN node performs video distribution, and the user plays video content through a playing device.
In this embodiment, the MEC node determines whether to upload the first video file after determining whether the content of the first video file is UGC, and determines the storage mode of the first video file according to the storage level of the first video file, so as to cache the video file with a high click rate, and enable a user to view the video content quickly and in time; the video content with low click rate is sent to the content production center for processing, so that frequent scheduling pull and push operations of the CDN node can be effectively reduced, and the occupation rate of limited bandwidth resources is effectively reduced.
Compared with the prior art that the video content shot by the user needs to be uploaded to the central media asset library firstly and then processed by using a specific coding and decoding server, the video content shot by the user can enter the MEC node, the embodiment has the advantages that the video content shot by the user directly enters the MEC node of the base station closest to the user for coding and decoding processing, the MEC node carries out downlink distribution on the processed video content, the processes of entering the central media asset library and the like can be utilized during leisure, the operation process is greatly reduced, the investment of an operator on a 5G network can be guaranteed to obtain the maximum profit, and the user can watch the video content timely and quickly.
