Detailed Description
The following description with reference to the accompanying drawings is provided to assist in a comprehensive understanding of the embodiments of the disclosure as defined by the claims and their equivalents. Various specific details are included to aid understanding, but these are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. In addition, descriptions of well-known functions and constructions are omitted for clarity and conciseness.
Currently, existing video resources are all stored in a content delivery network CDN server, and when a user wants to browse/watch a video, a user device needs to connect to the CDN server through the internet, as shown in fig. 1, which may cause network congestion and reduce a response speed for user access. In addition, if multiple users watch the same video at the same time in the same base station, network resources need to be reused, which also causes network congestion and resource waste. In addition, when a video application of the electronic device is started, the video application requires DNS resolution and internet connection, which results in a slow loading speed of a preview image of a video.
In view of the above and other problems, the present disclosure provides a MEC-based video playback control technique and a video playback technique, as shown in fig. 2. Fig. 2 illustrates an MEC-based video playback structure according to an exemplary embodiment of the present disclosure. In fig. 2, the video resources are deployed in the MEC server, and a plurality of user devices may share the video in the MEC server. The MEC server 600 may be configured/deployed to share the same video resource by multiple electronic devices, which may avoid duplicate production and wasted storage space. The user equipment can directly obtain the video from the MEC server without connecting to the CDN server through the Internet, thereby completing the fast switching and playing of the video. The MEC-based video playback control method and the video playback method will be described in detail below with reference to fig. 3 to 5.
Fig. 3 is a flowchart illustrating a video play control method for an MEC server according to an exemplary embodiment of the present disclosure. The video playback control method may be executed by the MEC server, or may be executed as a part of the MEC server.
Referring to fig. 3, at least a portion of each video in a content delivery network CDN server is downloaded and stored in advance by a MEC server at step S301. The MEC server may intercept and download the beginning piece of each of the entire videos included in the CDN server from the CDN server in advance and then store the beginning piece of each video in the memory of the MEC server. For example, the MEC server may intercept a video clip of the first five minutes of each video from the CDN server and then store the intercepted video clip of each video.
Furthermore, the MEC server may make at least a portion of each video intercepted in the form of a variable resolution video stream, enabling faster loading of the electronic device when obtaining the video from the MEC server. For example, the beginning segment of each intercepted video can be made into a video stream of DASH, HLS, etc. according to the protocols of DASH, HLS, etc. However, the above examples are merely exemplary, and the present disclosure is not limited thereto.
According to an embodiment of the present disclosure, the MEC server may download and store the complete video data of the current hotspot video in addition to downloading and storing the beginning segment of each video in the CDN server. In consideration of the huge access amount of the hotspot videos, the complete video data of the hotspot videos can be downloaded in advance, and network congestion caused by the fact that a large number of users access the CDN server independently is avoided. And considering that the hot videos are time-efficient, the MEC server may update the hot videos periodically.
Further, the MEC server may also generate preview images/thumbnails for the respective videos from at least a portion (such as the beginning clip) of each video stored. When a user starts a video application of the electronic equipment, the MEC server can quickly provide a video preview image required by the video application to the video application, so that the white screen condition is avoided. For example, the MEC server may provide a minimum resolution preview image to the video application.
In step S302, a video play request for acquiring a video is received from an electronic device. The video play request may include, but is not limited to, a video ID. When a user starts a video application of the electronic device, the video application may connect to the MEC server. Here, the video application may be connected with the MEC server via a wired network or a wireless network. When a user selects a certain video in a video application, the MEC server may receive a video play request for acquiring the video.
In step S303, in response to the video play request, the MEC server may provide at least a portion of the video corresponding to the video play request to the electronic device. Upon receiving the video play request, the MEC server may search for and determine whether the video is stored in the MEC server based on, for example, the video ID. When the video is present in the MEC server, the MEC server may provide at least a portion of the video (such as a beginning segment of the video) to the video application. The electronic device may load at least a portion of the video from the MEC server such that the user may view at least a portion of the requested video.
When the video does not exist in the MEC server, the MEC server may download and store at least a portion of the video from the CDN server to provide the at least a portion of the video to the electronic device. For example, the MEC server may automatically download and cache the beginning segment of the requested video from the CDN server.
When providing a corresponding video to an electronic device, the MEC server may determine whether to provide complete video data of the video to the electronic device according to a length of time that a user of the electronic device viewed the video. For example, when the user watches a corresponding video for more than half the duration of the beginning segment of the video stored in the MEC server, the MEC server may continue to provide the electronic device with the full video data of the video. However, the above examples are only exemplary, and different predetermined time periods may be set according to user requirements.
According to an embodiment of the present disclosure, in a case where complete video data of a hot video is deployed in an MEC server in advance, the MEC server may determine in which manner to continue to provide the rest of video data of the video to an electronic device according to whether a currently viewed video belongs to the hot video. Specifically, in response to the video belonging to the hotspot video, the MEC server may provide the full video data of the video directly to the electronic device. In response to the video not belonging to the hotspot video, the MEC server may redirect to a CDN server to obtain complete video data for the video.
Upon redirection to the CDN server to obtain the complete video, the MEC server may download and store the remaining video portions of the corresponding video from the CDN server, and then the electronic device obtains the remaining video portions of the video from the MEC server.
Optionally, when the electronic device is redirected to the CDN server to obtain the complete video, the MEC server may redirect the electronic device to the CDN server, so that the electronic device obtains complete video data of the corresponding video from the CDN server.
When the electronic device is redirected to the CDN server to obtain the complete video, the MEC server may determine, according to the number of users currently watching the corresponding video, what manner to use to enable the electronic device to obtain the complete video data of the video.
As an example, based on the number of users playing the corresponding video exceeding a predetermined threshold, the MEC server may download and store the complete video of the video from the CDN server, and then the electronic device may continue to retrieve the remaining video portion of the video from the MEC server. Based on that the number of users playing the corresponding video does not exceed the predetermined threshold, the MEC server may redirect the electronic device to the CDN server, so that the electronic device obtains a complete video of the video from the CDN server. Here, the predetermined threshold may be set according to a server configuration or the like.
Alternatively, the manner in which the electronic device is caused to acquire the complete video data of the video may be determined according to the access amount of the MEC server.
When a plurality of users watch the same video at the same time on the same MEC server, the MEC server can be connected with the CDN server to download the video and store the video to the MEC server, so that each user device does not need to download data from the CDN server independently, the broadband is saved, and the video playing is smoother.
According to the embodiment of the disclosure, the video resource of the MEC server can be shared by a plurality of user equipment. When a plurality of users watch the same video at the same time, the MEC server can download and provide the video to the user equipment from the CDN server, and the user equipment directly downloads the related video from the MEC server without redirecting to the CDN server, so that the time delay is reduced, and the network resources are saved. In addition, since the video resource of the MEC server can be shared by a plurality of user equipments, the waste of the manufacturing cost and the storage space can be avoided.
Fig. 4 is a flowchart illustrating a video playing method for an electronic device according to an exemplary embodiment of the present disclosure. The video playing method can be executed by the electronic equipment. The electronic device of the present disclosure may be any electronic device having a video playback function.
In accordance with embodiments of the present disclosure, an electronic device may include, for example, but not limited to, a portable communication device (e.g., a smartphone), a computer device, a portable multimedia device, a wearable device, and the like. However, the electronic device is not limited to those mobile terminals described above.
Referring to fig. 4, when a user selects a certain video among video applications of an electronic device, the video application may transmit a video play request for acquiring the video to a mobile edge computing MEC server at step S401. The video play request may include, but is not limited to, an ID of the corresponding video.
In addition, when the user starts the video application of the electronic device, the video application is connected with the MEC server, and a pre-generated video preview image can be acquired from the MEC server so as to be used for browsing and selecting the video content which the user wants to watch. When loading the preview image, the video application may automatically select the minimum resolution source to load the preview image. The pre-generated preview image is directly loaded from the MEC server through the video application, so that the occupation of internet network resources is avoided, and the loading speed is increased.
In step S402, in response to the video play request, the video application may obtain at least a portion of the requested video from the MEC server. When the user watches the current video for a time period exceeding a predetermined time period, the video application may continue to acquire/download the remaining video data of the current video from the MEC server.
In addition, under the condition that the MEC server connected with the electronic device downloads and stores the complete video of the hot videos in advance, if the currently watched video is the hot video, the MEC server has complete video resources, and at this time, the video application of the electronic device does not need to be connected with the CDN server, but continues to acquire/download the rest of video data of the current video from the MEC server. If the current video is a non-hotspot video, after the video application finishes downloading the video segments stored on the MEC server, the MEC server downloads the rest segments of the corresponding video from the CDN server, and then the video application continues to be downloaded from the MEC server. Optionally, if the previous video is a non-hotspot video, after the video application finishes downloading the video segment stored on the MEC server, the video application may redirect to the CDN server to continue downloading the remaining segments of the corresponding video.
When a user browses each video in the video application or the user quickly switches different videos, the video application can directly download the stored video segments from the MEC server, and the video application does not need to be connected to the CDN server, so that the connection/switching and downloading speed is improved, and the waste of network resources is reduced.
Fig. 5 is a schematic flowchart illustrating a video playing method according to an exemplary embodiment of the present disclosure.
Referring to fig. 5, in step S501, the MEC server may download and store the beginning segment of each video in the CDN server and the complete video data of the hotspot video in advance from the CDN server.
In addition, the MEC server may also periodically update the hotspot video. Optionally, the MEC server may also periodically download/update the beginning segment of the new video, so that more video resources are included in the MEC server.
In step S502, a video application of the electronic device is started. The video application may include various types of video applications.
In step S503, the video application of the electronic device may wirelessly connect with the MEC server, and the video application may acquire preview images/thumbnails of all videos required for the video application from the MEC server.
The MEC server intercepts and downloads the beginning segments of all videos from the CDN server in advance, and thus, a corresponding preview image can be generated based on the beginning segment of each video in advance. When a user starts a video application, the video application can directly acquire preview images of all videos required by the video application from the MEC server to realize rapid loading of the preview images of the videos, so that the situation that long waiting time is needed for displaying the preview images when the preview images of all the videos in the video application are loaded simultaneously is avoided. In particular, when a user rapidly turns pages in a video application, a corresponding preview image is loaded from the MEC server through the video application, and white screen can be avoided.
In step S504, when the user selects a video desired to be viewed through the video application of the electronic device, the video application transmits a video play request for acquiring the corresponding video to the MEC server. The video play request may include, but is not limited to, an ID of the corresponding video.
In step S505, in response to the video play request, the MEC server provides the beginning segment of the requested video. In the present disclosure, in order to meet the requirement of a user in fast browsing a video, the MEC server may provide the beginning segment of the video in the form of a variable resolution video stream when a video application downloads a video segment, so as to complete fast playing and switching of the video.
In addition, when the video requested by the user does not exist in the MEC server, the MEC server may download the beginning segment of the corresponding video from the CDN server according to the video ID in the video play request and store the beginning segment in the memory of the MEC server for the video application to load the segment of the video from the MEC server.
At step S506, the MEC server determines whether the user watches the corresponding video for more than a predetermined time, and if it is determined that the user watches the corresponding video for more than the predetermined time, proceeds to step S507, otherwise the MEC server may receive a new video playing request for acquiring another video, at which time the MEC server continues to send the beginning segment of the new video to the video application for the user to browse the other video.
In step S507, the MEC server determines whether the video currently watched by the user is a hot video, and when the currently watched video is the hot video, in step S508, the MEC server provides the video application with the complete video data of the video for the user to continue watching.
When the currently viewed video is not a hotspot video, since the MEC does not store the complete video data of the non-hotspot video, the MEC server may perform a redirection operation so that the video application acquires the complete video data of the video.
When performing the redirection operation, the MEC server may perform different operations according to the number of users viewing the current video.
In step S509, the MEC server may determine whether the number of users currently viewing the video exceeds a predetermined number, and proceed to step S510 when the number of users viewing the same video exceeds the predetermined number, otherwise proceed to step S511.
In step S510, based on the number of users playing the current video exceeding the predetermined threshold, the MEC server downloads and stores the complete video of the video from the CDN server, and then may continue to provide the video application with the complete video data of the video, i.e., the video application may continue to obtain the remaining video data of the video from the MEC server.
In step S511, based on that the number of users does not exceed the predetermined threshold, the MEC server redirects the electronic device to the CDN server, so that the video application of the electronic device obtains complete video data of the video from the CDN server.
Fig. 6 is a schematic diagram illustrating an MEC server according to an exemplary embodiment of the present disclosure. Referring to fig. 6, the MEC server 600 may include a memory 601, a transceiver 602, and at least one processor 603. Each component/unit in the MEC server 600 may be implemented by one or more components/units, and the name of the corresponding component/unit may vary according to the type of the component/unit. In various embodiments, some components/units in the MEC server 600 may be omitted, or additional components/units may also be included. Furthermore, components/units according to various embodiments of the present disclosure may be combined to form a single entity, and thus, functions of the respective components/units may be equivalently performed before being combined.
The MEC server 600 may be configured/deployed to share the same video resource by multiple electronic devices, which may avoid duplicate production and wasted storage space.
The processor 603 may pre-download at least a portion of each video in the CDN server and store at least a portion of each video in the memory 601. For example, the processor 603 may intercept the beginning segment of a long video (e.g., the first 5 minute video segment of the video), and then make the intercepted video segment into a variable resolution video stream (such as DASH, HLS, etc.) for placement in the memory 601. By making the video segments into a variable resolution video stream, the loading speed is made faster.
Further, the processor 603 may also generate a preview image/thumbnail of each video from the truncated beginning segment of each video. When a user launches a video application of the electronic device, the video application may connect with the MEC server 600, and the MEC server 600 provides preview images of all videos covered by the video application to the video application in response to the video application being launched. Therefore, when the user starts the video application, the video application can quickly load the preview image without occupying internet network resources, and the loading speed is improved.
When a user starts a video application of the electronic device, the video application is connected with the MEC server, and the processor 603 may receive a video play request for acquiring a video from the electronic device via the transceiver 602.
In response to the video playback request, the processor 603 may provide at least a portion of the requested video to a video application of the electronic device via the transceiver 602. When the requested video is not present in memory 601, the processor 603 may download and store at least a portion of the video from the CDN server.
The processor 603 may provide the video application with a full video of the current video based on the length of time the user viewed the current video. As an example, when a user watches a current video for more than half the duration of the beginning segment of the video stored in the MEC server, the processor 603 may redirect to the CDN server to obtain the remaining video data of the video. Since the processor 603 has enough time to buffer data during the pre-browsing playback, the startup playback speed and smoothness can be improved, and network congestion can be reduced.
In the case where the MEC server stores a complete video of the hot video, the processor 603 may determine in which manner to continue to provide the remaining video data of the video to the electronic device according to whether the currently viewed video is the hot video. In particular, in response to the video belonging to a hotspot video, the processor 603 may provide the full video data of the video directly to the electronic device. In response to the video not belonging to the hotspot video, the processor 603 may redirect to a CDN server to obtain complete video data for the video.
In the redirection, the processor 603 may download and store the remaining video segments of the corresponding video from the CND and then provide to the video application. Optionally, the processor 603 may redirect the video application to the CDN server such that the video application buffers the remaining video segments of the respective video from the CDN server. Alternatively, the processor 603 may determine, according to the number of users currently watching the corresponding video, in which manner the electronic device obtains the complete video data of the video. For example, based on the number of users playing the current video exceeding a predetermined threshold, the processor 603 may download and store the complete video of the video from the CDN server and then provide to the video application. Based on the number of users not exceeding the predetermined threshold, the processor 603 may redirect the video application to the CDN server such that the video application obtains a complete video of the video from the CDN server.
Fig. 7 is a schematic diagram illustrating an electronic device according to an exemplary embodiment of the present disclosure. Referring to fig. 7, an electronic device 700 may include a transceiver 701, at least one processor 702, and a display 703. Each component/unit in the electronic device 700 may be implemented by one or more components/units, and the name of the corresponding component/unit may vary according to the type of the component/unit. In various embodiments, some components/units in electronic device 700 may be omitted, or additional components/units may also be included. Furthermore, components/units according to various embodiments of the present disclosure may be combined to form a single entity, and thus, functions of the respective components/units may be equivalently performed before being combined.
When a user selects a certain video in a video application of the electronic device, the processor 702 may send a video play request for acquiring the video to the MEC server through the transceiver 701 via the video application. The video play request may include, but is not limited to, an ID of the corresponding video.
Further, when the user starts a video application of the electronic device, the processor 702 is connected with the MEC server, and the video application may acquire a pre-generated video preview image from the MEC server for the user to browse and select desired video content through the display 703. The pre-generated preview image is directly loaded from the MEC server through the video application, so that the occupation of internet network resources is avoided, and the loading speed is increased.
The processor 702 may obtain at least a portion of the requested video from the MEC server via the transceiver 701. The processor 702 may obtain video from the MEC server in the form of a variable resolution video stream to increase loading speed.
When the user watches the current video for more than a predetermined time period, the processor 702 may continue to acquire/download the remaining video data of the current video from the MEC server.
In addition, under the condition that the MEC server connected to the electronic device downloads and stores the complete video of the hot video in advance, if the currently viewed video is the hot video, and the MEC server has complete video resources, the processor 702 does not need to be connected to the CDN server again, but continues to acquire/download the remaining video data of the current video from the MEC server. If the current video is a non-hotspot video, after the processor 702 may download the video segments stored on the MEC server, the processor 702 continues to download from the MEC server after the MEC server downloads the remaining segments of the corresponding video from the CDN server. Alternatively, if the previous video is a non-hotspot video, the processor 702 may redirect to the CDN server to continue downloading the remaining segments of the corresponding video after downloading the video segment stored on the MEC server.
When a user browses each video in the video application or the user quickly switches different videos, the video application can directly download the stored video segments from the MEC server, and the processor 702 does not need to be connected to the CDN server, so that the connection/switching and downloading speed is improved, and the waste of network resources is reduced.
