Detailed Description
Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Currently, OTT TV mainly HAS two implementations of HPD and HAS, and conventional OTT TV generally adopts HPD technology. The HPD-based client only needs to wait a short period of time for downloading and buffering the forefront part of the data of the media file before starting playing, and then can play while downloading. However, HPD technology has a number of limitations, including: the method is not suitable for transmitting live programs with high real-time requirements; the waiting time delay of the initial play is generally longer; when the network bandwidth is unstable, the screen blocking phenomenon is easy to occur; since the client can continue to download video files, when the user gives up watching a program halfway, it can result in wastage of downloaded files (consuming bandwidth).
To overcome the limitations of HPD technology, HAS-based OTT TV technology is increasingly being widely adopted and popularized by the industry. The HAS technique adopts video slicing and adaptive code rate techniques. In the HAS system, a media stream splitter splits the video stream output by an encoder into a series of consecutive small fragmented files of equal length and stores them in a Web content distribution server. The HAS client device may automatically request a fragmented file of appropriate video quality (i.e., different resolution and code rate) from the Web server based on available bandwidth, thereby giving the user the best visual experience.
However, the series of continuous, equally-sized small fragmented files, i.e., video slice data, can only serve HAS client devices, but cannot serve HPD client devices. If the HPD client device is to be serviced, the video content must be stored again in HPD format as HPD content. Storing the same video content twice can occupy network resources while wasting storage space of the Web content distribution server. In addition, the traditional HPD content is stored as a complete large file, the whole file needs to be downloaded again under the condition of fragment loss, and the storage of the HPD large file cannot well utilize the advantages of cloud storage and is stored in different storage systems in a distributed mode. Therefore, the embodiment of the invention provides a video playing method, so that video slice data can also provide services for HPD client equipment.
Embodiments of the present invention will be described below with reference to the accompanying drawings.
Referring to fig. 1, fig. 1 shows a flowchart of a video playing method according to an embodiment of the present invention, where the method includes the following steps:
step S110: and receiving a video playing request sent by a user.
In this step, the video play request contains a key information content ID and a user ID. As shown in fig. 2, after receiving a video playing request sent by a user, i.e., a client, the CDN user server determines whether the request is an HPD video playing request or a streaming media (HAS) playing request according to a key information content ID in the video playing request.
Step S120: and when the video playing request is to play the HPD video, acquiring an index file according to the playing request.
With continued reference to fig. 2, when the CDN user server determines that the video play request is to play the HPD video, the CDN user server may continue to send the video play request to the content module. After receiving the video playing request, the content module downloads an index file corresponding to the video content from the cloud storage space according to the information of the video content to be played by the user in the video playing request, returns the corresponding index file to the CDN user server, and stores the index file in the CDN user server.
Step S130: and acquiring video slice data according to the index file.
With continued reference to fig. 2, after receiving the corresponding index file, the cdn user server sends a request for acquiring video slice data to the content module according to the download address in the index file and the order of the index file. And then, the content module sequentially downloads video slice data from the cloud storage space according to the sequence of the index file, namely the time sequence of video content playing, and returns the video slice data to the CDN user server. Wherein the video slice data is a series of continuous, equally-sized small slice files of size typically around 10 seconds, divided by the complete video content.
Specifically, the manner in which the content module downloads video slice data from the cloud storage space according to the index file may be: acquiring code rate information of a playing video according to the index file; and acquiring video slice data of the corresponding code rate according to the code rate information.
The index files comprise a primary index file and a secondary index file. The primary index file stores code rate information of the played video and a download address of a video file (secondary index file) corresponding to each code rate. The secondary index file stores the download address of the video slice data with the same code rate. The content module selects a secondary index file corresponding to the code rate from the primary index file according to a preset default code rate, and downloads corresponding video slice data from the cloud storage space through a download address in the secondary index file.
Step S140: and splicing the video slices into HPD video in real time.
Step S150: and sending the HPD video to the user.
With continued reference to fig. 2, when the CDN user server receives the video slice data, the CDN user server splices the video slice data according to the downloading order and splices the video slice data into an HPD video, because the video slice data cannot directly provide services for the HPD client device. And then returning the HPD video to the client for the user to watch the video. While the user watches the video, the CDN user server can continuously splice the video slice data downloaded subsequently, so that the effect of real-time splicing is achieved.
According to the embodiment of the invention, the type of the played video is judged and the index file is acquired through the video playing request sent by the user. When the type of the play video is HPD video, video slice data are acquired according to the index file, and are spliced into HPD video, and the HPD video is returned to the client. Through the mode, the embodiment of the invention realizes the content of the same video slice data, and can be simultaneously applicable to two service scenes of HAS and HPD. Therefore, the server only needs to store one content, so that node resources are saved, and the storage space of the server is occupied less.
Referring to fig. 3, fig. 3 is a flowchart illustrating a video playing method according to another embodiment of the present invention, and the difference between the present embodiment and the above embodiment is that, after step S110, the method further includes:
step S210: and when the video playing request is a streaming media playing request, acquiring an index file according to the playing request.
Step S220: and acquiring video slice data according to the index file.
Step S230: and sending the video slice data to the user.
As shown in fig. 4, when the CDN user server determines that the video play request is a streaming media play request, the CDN user server also continues to send the video play request to the content module as in the above embodiment. The content module also downloads the index file from the cloud storage space and returns the index file to the CDN user server. However, after receiving the index file, the CDN user server returns the index file to the client, where the client selects video slice data of a suitable quality (i.e., different resolutions and code rates) according to the current network situation. The client can select a proper code rate according to the content of the primary index file in the index files, and determine the secondary index file corresponding to the code rate. The client may then send a video slice data acquisition request to the CDN user server based on the secondary index file. The CDN user server forwards the request to the content module, and the content module downloads corresponding video slice data from the cloud storage space according to the download address in the secondary index file determined by the client and returns the video slice data to the CDN user server.
In addition, contrary to the above embodiments, the CDN user server returns the video slicing data to the client immediately after receiving the video slicing data, so that the user can directly watch the video slicing data. While watching, the client side also always sends a video playing request so as to ensure that the client side can continuously receive video slice data.
Referring to fig. 5, fig. 5 shows a flowchart of a video playing method according to another embodiment of the present invention, and the difference between the present embodiment and the above embodiment is that the method further includes:
step S310: and receiving a code rate replacement request sent by a user.
As shown in fig. 6, the user selects a new code rate according to the current network condition to obtain a proper video quality, and sends a code rate replacement request to the CDN user server through the client.
Step S320: and acquiring video slice data of the corresponding code rate according to the code rate replacement request.
After receiving the code rate replacement request, the CDN user server selects a secondary index file corresponding to the new code rate from index files stored in the CDN user server according to the new code rate in the code rate replacement request, and then sends a new code rate video slice data acquisition request to the content module according to the secondary index file. And after receiving the request, the content module downloads the corresponding video slice data from the cloud storage space according to the download address in the secondary index file and returns the video slice data to the CDN user server.
Step S330: and splicing the video slice data into HPD video in real time.
Step S340: and sending the HPD video to the user.
As in step S140 and step S150, the CDN user server will splice the video slice data into an HPD video before sending the HPD video to the client for viewing by the user.
Because the HPD technology has no code rate self-adaption function, the embodiment of the invention replaces the original video slice data with the code rate video slice data required by the user through the code rate replacement request initiated by the user, and splices the video slice data into the HPD video so as to provide service for the HPD client device and promote the user experience of the HPD client device.
Referring to fig. 7, fig. 7 is a flowchart illustrating a video playing method according to still another embodiment of the present invention, where the method further includes:
step S410: and determining a new video code rate according to the packet loss rate of the current network.
Step S420: and acquiring video slice data of the corresponding code rate according to the new video code rate.
Step S430: and splicing the video slice data into HPD video in real time.
Step S440: and sending the HPD video to the user.
With continued reference to fig. 6, the cdn user server may also determine a new video code rate according to a packet loss rate of the current network, i.e., the current network quality. As in the above embodiment, after the CDN user server determines the new video code rate, a secondary index file corresponding to the new code rate is also selected from the index files stored in the CDN user server, and then a new code rate video slice data acquisition request is sent to the content module according to the secondary index file. And after receiving the request, the content module downloads the corresponding video slice data from the cloud storage space according to the download address in the secondary index file and returns the video slice data to the CDN user server. Similarly, as in step S140 and step S150, the CDN user server will splice the video slice data into HPD video before sending the HPD video to the client for viewing by the user.
According to the embodiment of the invention, the code rate is automatically adjusted through the CDN user server, the original video slice data is replaced by the video slice data with the code rate suitable for the current network condition, and the video slice data is spliced into the HPD video, so that service is provided for the HPD client device, and the user of the HPD client device and the user of the HAS client device have the same experience.
Referring to fig. 8, an embodiment of the present invention further provides a video storage method, as shown in fig. 8, including:
step S510: and acquiring a video file.
As shown in fig. 9, the client sends a video cache request to the content module through the CDN management platform, and the content module downloads a video file from the source station after receiving the request, and determines whether the video file is an HPD video file or a HAS video file. The source station is a server of a video website accessed by the client, and stores all video files contained in the video website.
Step S520: when the video file is an HPD video file, performing video slicing processing on the HPD video file according to preset video slicing time.
With continued reference to fig. 9, after the content module determines that the video file is an HPD video file, the video file is divided into a series of video clips with the same duration according to the preset transcoding code rate of the video clip duration, and the video clips are stored with different code rates, and are converted into each preset transcoding code rate and respectively stored in the cloud storage space. For example, the pre-set transcoding rates are a, b, and c, and the series of video slices are stored as a1-an, b1-bn, and c1-cn, respectively.
Step S530: and generating an index file according to the video fragments.
The content module generates a video fragment and generates a corresponding index file according to the video fragment. The index file comprises the playing code rate information of the corresponding video clips. The content module generates a plurality of secondary index files according to the code rate of each video fragment, wherein each secondary index file comprises the download addresses of all video fragments on the cloud storage space under a code rate. The download addresses of the secondary index files and the corresponding code rates form a primary index file. For example, the video slices generated in the above steps have video slices a1-an with a code rate a, video slices b1-bn with a code rate b, and video slices c1-cn with a code rate c. The download addresses of the video clips a1-an are stored in the secondary index file A, the download addresses of the video clips B1-bn are stored in the secondary index file B, and the download addresses of the video clips C1-cn are stored in the secondary index file C. The download address of the secondary index file A on the cloud storage space and the code rate a corresponding to the download address, the download address of the secondary index file B on the cloud storage space and the download address of the secondary index file B and the download address of the secondary index file C on the cloud storage space and the code rate C corresponding to the download address are stored in the primary index file. The primary index file and the secondary index file together form the index file.
Step S540: and storing the HPD video file as a video fragment and a corresponding index file.
In the step, the content module firstly stores the HPD video file in the cloud storage space; generating a secondary index file according to the download address of the HPD video file in the cloud storage space, and storing the secondary index file in the cloud storage space; and finally, generating a primary index file according to the download address of the secondary index file in the cloud storage space, and storing the primary index file in the cloud storage space.
Then, when the HPD user needs to watch the video file, the HPD user can splice the video fragments into HPD video. When the HAS user needs to watch the video file, the content module does not need to download the new video file again, but can directly use the video clip.
In some embodiments, the content module may send various status information (including successful storage of the video file or successful storage of the index file) to the CDN management platform, and then the content module is sent to the client by the CDN management platform, so that the user can understand the storage progress, and user experience is improved.
The embodiment of the invention divides the HPD video file into video fragments, so that the video file can be simultaneously suitable for HPD users and HAS users. Therefore, only the divided HPD video files need to be stored in the cloud storage space, so that the storage space is greatly saved, and network resources for downloading the video files are also saved.
