Abstract

The embodiment of the application discloses a video playing method and related equipment, which can reduce the starting time delay of a video under the condition of playing the video with a watermark. After receiving a first request sent by a client through CDN edge node equipment, a CDN source station server generates a broadcast start index file in real time, wherein the broadcast start index file comprises a download address corresponding to a broadcast start playing sequence, and the broadcast start playing sequence is a sequence corresponding to a segment of video segment at the beginning of a video or a segment of video segment after a video skips over a segment head; and then, the CDN source station server sends the broadcast index file to the client through CDN edge node equipment. Because the data volume contained in the start-up playing index file is less, the time occupied by generation and transmission is less, the client can acquire the start-up playing index file in a shorter time, and then download the video content according to the download address corresponding to the start-up playing sequence for start-up playing, thereby achieving the purpose of reducing the video start-up playing time delay.

Description

A kind of video broadcasting method and relevant device

Technical field

This application involves field of computer technology more particularly to a kind of video broadcasting methods and relevant device.

Background technique

Video content provider is illegally revealed in order to avoid video, it will usually add watermark in video (watermarking).The watermark added in video is generally implicit watermark, and implicit watermark is digital signal for identification, no It will affect the visual quality of viewing video.If video is illegally revealed, can by the watermark information in the video that leaks out, Tracing back to is which user leaks out this video, to protect the legitimate rights and interests of video content provider.

The method of cloud side addition watermark is the method for currently used addition watermark.The principle of this method is: passing through first One video code conversion is A stream, B two video mediums of stream by transcoding platform, includes multiple in A stream and the video medium of B stream Video slicing.Wherein, the video content of the video slicing of same slice position in multiple video slicings that A stream and B stream include Identical (for example, the fragment 1 of A stream is identical as the video content of fragment 1 that B flows), but added in the video slicing of A stream and B stream Watermark is different.For different users, different video slicings can be chosen in A stream and B stream and form play sequence.Example Such as, the play sequence for the video that user 1 gets may be A stream fragment 1, fragment 3, fragment 4, fragment 6 ... and B stream point Piece 2, fragment 5, fragment 7 ...；The play sequence for the same video that user 2 gets may be the fragment 2 of A stream, fragment 3, fragment 4, fragment 7 ... and B stream fragment 1, fragment 5, fragment 6 ....Since A flows the watermark added in the video slicing flowed with B mutually not It is identical, it, can be with by the watermark sequence in detection video then the play sequence of different user corresponds to different watermark sequences The video of retrospect leakage is which user gets.

At this stage, during program request has the video file of watermark, the client of user will pass through content delivery network Network (content delivery network, CDN) edge node devices obtain from CDN source station server and play index file (for example, playing index file can be MPD file or M3U8 file).This index file is CDN source station server according to use What user's unique identification (unique ID) of family playing request generated in real time, which includes the entire play sequence pair of video The download address (for example, uniform resource locator (uniform resource locator, URL)) answered.This index file After generation, CDN source station server will send the index file to CDN edge node devices, and CDN edge node devices are again by the rope Quotation part is sent to the client of user；Later, the client of user will download view according to the download address in the index file Frequency division piece carries out video playing.

In above process, being likely to result in biggish sowing time prolongs, so that user waits video to act the time broadcast It is too long, user experience is seriously affected, causes user to play abandonment rate excessively high.The main reason for having caused sowing time to prolong has been broadcasting rope The generation time of quotation part and delivery time are longer.The video of a length of 2 hours when for example, for one, if 5s mono- Fragment, a video generate 7 kinds of code rate media and 1 tunnel audio；Then the index file shares 2*3600/5*8=11520 (item) The information of fragment, the time that burst information amount causes greatly very much CDN source station server to generate index file are longer.In addition, video point Broadcast MPD (the media presentation description) index file generally used using Dash agreement, Dash agreement The broadcasting URL of the video slicing of all resolution ratio/code rates is put in an index file.Index file is larger, will be so that CDN Edge node devices are obtained from the client that CDN source station server obtains index file and user from CDN edge node devices Index file can all generate biggish time delay.When how to solve to play the video for having watermark, a sowing time, which prolongs larger problem, is Those skilled in the art's urgent problem to be solved.

The some concepts being related in the embodiment of the present application will further be introduced below.

The index file (or referred to as media description file) of video, for recording under the video slicing for forming the video Set address (for example, uniform resource locator).Index file is made of data file, it is the sequential file of tape index.Index File is made of concordance list and master file two parts, and concordance list is corresponding relationship between instruction logic record and a physical record Table.Each in concordance list is referred to as index entry, and index entry is arranged according to the sequence of key (or logic record number).If index text Part itself be also according to keywords sequence arrange, then referred to as index sequential file.Otherwise, referred to as indexed non-sequential file.Citing and Speech, in the embodiment of the present application, the index file of the video can be the file of UTF-8 coded format, for example, the index file It can be MPD file or M3U8 file.Client can be downloaded according to the download address of the video slicing recorded in index file Video slicing carries out video playing.

Video slicing, the segment of a length of 2 seconds~10 seconds sizes when being in a video.One video is regarded by one or more Frequency division piece composition.Fragmentation, available different fragment result are carried out using different sliced fashions to the same video. For the same video, there are A to flow for the video, B flows two video mediums (passing through transcoding platform processes in advance), A stream It include multiple video slicings in the video medium flowed with B.Wherein, identical point in multiple video slicings that A stream and B stream include The video content of the video slicing of piece position is identical (for example, the fragment 1 of A stream is identical as the video content of fragment 1 that B flows), but A The watermark added in the video slicing of stream and B stream is different.

The sequence of video slicing, that is, the sequence of the video slicing of the A stream and B stream chosen.For example, what user 1 got The play sequence of video may be A stream fragment 1, fragment 3, fragment 4, fragment 6 ... and B stream fragment 2, fragment 5, fragment 7,…；The play sequence for the same video that user 2 gets may be the fragment 2 of A stream, fragment 3, fragment 4, fragment 7 ... and B The fragment 1 of stream, fragment 5, fragment 6 ....It is same since the watermark added in the video slicing of A stream and B stream is different The watermark sequence for including in the sequence of the different video fragment of a video is different.

It referring to fig. 2, is that the embodiment of the present application provides a kind of flow chart of video broadcasting method, this method can be based on Figure 1A Shown in framework realize that first server described below can be the CDN source station service in system architecture shown in figure 1A Device.It should be noted that in system architecture shown in Figure 1B~Fig. 1 D this method can also be applied, it is only necessary to adjust equipment room Communication process (can refer to above-mentioned example).This method includes but is not limited to following steps.

S201, client send the first request to CDN edge node devices.

Wherein, this first requests index file for requesting video.Optionally, in the embodiment of the present application, this first The corresponding video of request is not the locally stored video of the client, and the video is the video with watermark.In visitor Before family end sends the first request to CDN edge node devices, the program request for video that client can receive user's input is asked It asks.If first video is not the locally stored video of the client, and the video is the video with watermark, client Broadcasting authentication request will be sent to authentication server is played, which is used to indicate the broadcasting authentication server to this Client accesses the judgement of permission.If the broadcasting authentication server determines that the client has the visit to content distributing network Ask permission, then the broadcasting authentication server is by the authentication is passed as a result, later, client can be to content point to client feedback The CDN controlling equipment of hairnet network sends scheduling request.In response to the scheduling request, CDN controlling equipment will be to client feedback point The information for the CDN edge node devices matched.Then, the client can be sent to the CDN edge node devices of the distribution this One request.

S202, after the CDN edge node devices have received the first request from the client, CDN edge node devices The first request of the client is sent to first server.

Optionally, in response to first request, whether CDN edge node devices determine the corresponding video of first request It is the CDN edge node devices in locally stored video.If the video is the video with watermark, then, different clients End will be corresponding with different index files, and CDN edge node devices determine the index file of itself not stored video, the CDN Edge node devices will request the index file of the video to CDN source station server (first server).Therefore, the edge CDN Node device sends the first request of the client to first server, correspondingly, the first server is set from CDN fringe node Standby the first request for receiving client.

S203, the first server from CDN edge node devices receive client first request after, this first clothes Business device sends third request to second server.

Wherein, third request further includes that this broadcasts play sequence in third request for having requested to broadcast play sequence Setting parameter (for example, acting the maximum value for broadcasting the play time of play sequence, or rise and broadcast the fragment position of play sequence most Big value).It in one possible implementation, further include the play time or the view of the video title in third request The fragment position of frequency head.

S204, second server from first server receive the third request after, which, which has generated, broadcasts Play sequence.

Wherein, this broadcasts the sequence for the partial video fragment that play sequence is the video.Optionally, this broadcasts play sequence There may be two kinds of possible situations.The first situation, this broadcast play sequence be the video the first preset play time it The sequence of preceding video slicing, or the sequence for the video slicing before the first default fragment position of the video.Second Situation, after this broadcasts the play time for the head that play sequence is the video, and before the second preset play time After the sequence of video slicing, or fragment position for the head of the video, and before the second default fragment position The sequence of video slicing.That is, the maximum value that this broadcasts the play time of play sequence may be first preset play time, It may be second preset play time；The maximum value for acting the fragment position for broadcasting play sequence may be the first default fragment position It sets, it is also possible to be the second default fragment position.It should be noted that if user is provided with " skipping head " in the client, This, which rises, broadcasts the second situation that play sequence should be above-mentioned, if user does not carry out the setting of " skipping head ", this broadcasting sequence Column should be the first above-mentioned situation.As can be seen that this, which rises, broadcasts one section of video clip or view that play sequence starts for video Chatter crosses the sequence for the video slicing for including in one section of video clip after head.

Optionally, first preset play time, the first default fragment position, the second preset play time or second are pre- If fragment position, these, which rise, broadcasts the setting parameter of play sequence and can be configured according to demand.For example, this first default is broadcast Putting the time can be the 1st minute, the 2nd minute, etc.；The second default fragment position can be the 12nd fragment, the 13rd fragment, etc. Deng.Second preset play time can be the 4th minute, the 5th minute etc.；The second default fragment position can be the 48th point Piece, the 50th fragment etc..It is the more provided by the embodiments of the present application setting parameter for broadcasting play sequence referring to Fig. 3 A~Fig. 3 D Schematic diagram.It should be noted that the dark lattice illustrated in Fig. 3 B and Fig. 3 D have represented the video point broadcast and include in play sequence Piece, blank cell represent this and act the video slicing broadcast and do not included in play sequence.In addition, between the adjacent video slicing illustrated in figure It is not represent between adjacent video slicing in playing process that there are gaps to distinguish different video slicings there are gap.

Optionally, second preset play time can also by the head time of video plus preset time interval come It determines, which can be determined by the fragment position of the head of video plus preset fragmentation interval. By to the first preset play time, the first default fragment position, the second preset play time or the second default fragment position Adjustment, adjustable is broadcast the length of play sequence, it can Indirect method, which rises, broadcasts the size of index file.

S205, the second server send rising for the video to the first server and broadcast play sequence.

S206, after the first server broadcasts play sequence from obtaining the video in the second server, this This of one server generation broadcasts play sequence corresponding and broadcasts index file, and it has included broadcasting play sequence in index file that this, which broadcasts, Corresponding download address.

In first server, A stream, the B that the video has been stored in advance flow two video mediums (in advance by transcoding platform Processing) in each video slicing download address (for example, URL).The first server can rise according to this and broadcast play sequence, And A stream, the B of the video flow the download address of each video slicing in two video mediums, have generated and have broadcast index file.It should Rise broadcast in index file including the video rise broadcast the corresponding download address of play sequence.Play sequence is broadcast since this rises as the view The sequence of the partial video fragment of frequency, then it is smaller that rising of generating broadcasts the data volume that index file includes, so that generating and passing It is less that this defeated broadcasts the index file occupied time.

It is as follows one and acts the example for broadcasting index file (listing resolution ratio/code rate index file information):
