Abstract
The invention discloses a live broadcast time shift method which is applied to a live broadcast network including a client and a server. The live broadcast time shift of a user on the client is divided into pause and play. The client acquires the time label of a first index file currently parsed by the client according to pause, and acquires the played time of a video clip corresponding to the first index file. The client determines the timestamp of pause in a live broadcast video according to the time label and the played time. When the client receives play, a live broadcast time shift request is sent to the server according to the time shift time and timestamp of play. The live broadcast video in the live broadcast network is parsed and played according to a second index file returned by the server. After a user who watches live broadcast carries out live broadcast time shift, discontinuous screen caused by play screen hysteresis and play delay is reduced, and the user experience is improved. The invention further discloses the client.
Description
Technical field
The present invention relates to net cast technical field, more particularly to a kind of direct broadcast time-shift method and client.
Background technology
It is live increasingly to be favored by people with the continuous development of the Internet.As realize it is live institute it is essential
Technology, HLS (HTTP Live Streaming, HTML (Hypertext Markup Language) dynamic code rate self adaptation) is used for PC and mobile terminal
Audio frequency and video service.
HTTP Live Streaming (HLS) is the Streaming Media based on HTTP that Apple (Apple Inc.) realizes
Host-host protocol, is capable of achieving the live and program request of Streaming Media, is mainly used in iOS system, is iOS device (such as iPhone, iPad)
There is provided that audio frequency and video are live and demand scheme.HLS program requests, are basically common segmentation HTTP program requests, and difference is, it point
Duan Feichang is little.
Relative to common live streaming media agreement, such as RTMP agreements, RTSP agreements, MMS etc., HLS is live most
Big difference is that what live client got, be not a complete data flow.HLS protocol will be straight in server end
Multicast data stream is stored as media file (MPEG-TS forms) continuously, very long in short-term, and client is then constantly downloaded and broadcast
These small documents are put, always because newest live data can be generated new small documents by server end, as long as such client
The file got from server is ceaselessly played in order, is achieved that live.As can be seen here, substantially it is believed that HLS
Be realized with the technical approach of program request it is live.Because data are transmitted by http protocol, so completely dispensing with consideration fire wall
Or the problem of agency, and the duration of segmental file is very short, selection and switching code rate that client can be quickly, to adapt to not
With the broadcasting under bandwidth condition.The but this technical characterstic of HLS, the delay for determining it can be higher than typically always common stream
Medium living broadcast agreement.
Due to the regulation of HLS protocol, the index text of the M3u (8) for needing to delete old in real time during data stream transmitting
Part, if client is when deleted M3u (8) index file is asked during data stream transmitting, server then cannot be carried out
Audio/video pushing.And as described above, data can be higher than always that common Streaming Media is straight by the delay that http protocol is transmitted
Agreement is broadcast, so the current of direct broadcast time-shift is also unable to reach zero-lag or the delay of very little.Therefore, when user is in live process
It is middle realize suspend and backward the function of redirect broadcasting when, only client by transformation support request special time function with
And service end is inadequate by the file index function that transformation is supported to preserve play history.This is because using FTP client FTP
Current time System current Time Millis realize that live time-out is played and time-shifting function is by client
Player provides timing time, but due to client operating system with server sync when might have error, add broadcasting
Device is prepared broadcasting and also can consume the regular hour when downloading, and in the case where network condition is general, can exist very big
Time delay.
As can be seen here, the entrained corresponding reality of timestamp when to server request live video of client how is guaranteed
Border playing progress rate time actual play progress corresponding with the timestamp of the live video that server is handed down to client is coincide, from
And reduce in the playing process for recovering live video, discontinuously feel to the picture that user brings, become those skilled in the art
The technical problem urgently to be resolved hurrily in the Consumer's Experience during raising is live.
The content of the invention
The invention provides a kind of direct broadcast time-shift method and client, service during the time shift operation when occurring live with being eliminated

Specific embodiment
As stated in the Background Art, in prior art when the function of live pause is processed, record is the local of client
Time, when then proceeding to play, record time-out elapsed time is poor, and request server carries out re-issuing new m3u8 indexes text
Part, the method does not consider server to the time delay of client, so as to precision does not reach requirement, Consumer's Experience compared with
Difference.When another kind of method is moved in process direct broadcast time-shift progress bar, using the local zone time of client as benchmark,
To carry out issuing m3u8 index files, the delay between server and client is not accounted for yet, can there is higher delay yet,
Affect the experience of user.
In view of problem above of the prior art, the present invention proposes a kind of direct broadcast time-shift method, is applied to include clothes
In the Living Network of business device and client.For ease of carrying out rationally clearly illustrating to the technical scheme of the application, in description originally
Before the technical scheme of invention, first the principle of net cast is illustrated：
When carrying out live for one section of video, first the video is divided into according to prefixed time interval in server end
Multiple video slicings, an index file is generated according to default video length, and generally the index file is m3u8 files, should
The summary and information of multiple video slicings are contained in index file, client can be according to this after the index file is received
Carrying out the download of corresponding video slicing and be played accordingly, the technical scheme of the application is then for information in index file
It is the delay proposition for producing during the operation of user's generation time-out or time shift during net cast.
Below in conjunction with the accompanying drawing in the application, the technical scheme in the application is clearly and completely described, is shown
So, described embodiment is only a part of embodiment of the application, rather than the embodiment of whole.Based in the application
Embodiment, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, all
Belong to the scope of the application protection.
As shown in figure 1, a kind of schematic flow sheet of the direct broadcast time-shift method proposed for the embodiment of the present invention, the method application
In the Living Network including server and client side, it should be noted that the server in the Living Network possesses in itself regarding
Frequency store function, can be divided into multiple video slicings to needing to carry out live live video to cut into slices by live video, press
An index file is generated according to the video length for pre-setting, an index file corresponds to multiple video slicings, each index
File has the time tag of itself, and the generally time tag is first in the corresponding multiple video slicings of the index file
The start time point of video slicing, usual direct broadcast server is a Cloud Server, naturally it is also possible to be PC ends as server
Through forwarded, and can also be able to be a PC for a mobile terminal for client, the technical side of the application
Case is operated mainly for the direct broadcast time-shift in the playing process for being entered performing network living broadcast video based on HLS protocol.The method is concrete
Step is as follows：
Step 101, client obtains the time tag of the first index file that client is currently parsed according to pausing operation,
And the playing duration of video slicing corresponding with the first index file.
In actual application scenarios, when direct broadcast time-shift operation is carried out in user's viewing live video, the time shift operation one
As to suspend, (in actual application scenarios, user can be suspended or rollback, when seeing both of these case unification as live
Operation is moved, wherein, user carries out carrying out the situation of continued broadcasting after pausing operation, and the situation regards during direct broadcast time-shift a length of 0 one kind as
Situation), two kinds of situations of rollback, and direct broadcast time-shift operation typically has time shift duration and the timing node of the operation occurs, when
Move the timing node of duration record of lead when can add by the length of progress bar to obtain, and for timing node, lead to
The normal simply timing node local for client of record, when direct broadcast time-shift operation is to suspend as a example by illustrate, suspending
After proceed live video play when, record suspend elapsed time it is poor, request server re-issues new index file,
Can there is the time delay of client when so re-starting broadcasting.
For above-mentioned situation, in the application preferred embodiment, the direct broadcast time-shift division of operations of user is grasped to suspend
(pausing operation herein is considered as the straight of user to work with a kind of broadcast state that play operation is client, here with play operation
It is two steps to broadcast time shift operation, and first step carries out halted state for client, and second step is entered into for client
Broadcast state, here for convenience of explanation, is divided into pausing operation and play operation, should be noted straight with aforesaid user
The pausing operation for broadcasting one of the type of time shift operation makes a distinction.), wherein, dragged when user customer carries out progress bar
Cheng Zhong, first clicks on the progress bar chosen in client, or when being operated using keyboard or the input of manual palpation lamp, client
End carries out first halted state, and the client such as (i.e. time shift duration select after) is corresponding after user carries out progress bar movable length
After operation, client enters broadcast state, it is believed that user carries out completing play operation, equally in the technical scheme of the application
In, in the direct broadcast time-shift operation of user, time when user's generation direct broadcast time-shift is operated is obtained according to the pausing operation of user
Stamp, according to the play operation of user the time shift duration of user live broadcast time shift operation is obtained.
Based on the above, each index file in server has the time tag of itself, in order that get
The timing node of time-out is synchronous with the holding of the time of server side, so need to be defined according to the time tag of index file, root
The time out stamp synchronous with server side is determined according to the time migration of the video slicing played.When user is in straight
Broadcast the live client of state carry out direct broadcast time-shift operate when, active client player enters halted state, client records
The time tag of the first index file of current parsing, and calculate the video slicing played in current first index file
The duration value of number and each video slicing, according to the quantity and duration of playing video slicing the first index file pair is determined
The playing duration of the video slicing answered.
Step 102, client determines pausing operation in the live of Living Network according to time tag and playing duration
Timestamp in video.
As described in step 101, calculate current live time shift operation relative to the time tag of the first index file when
Between change, that is, current hang operate relative to server side timing node time migration, it is true according to the time migration
Making direct broadcast time-shift operates the correct time relative to server side to stab, it is to avoid using client local zone time as timestamp
The delay of generation.
The playing duration of the time tag of the first index file video slicing corresponding with the first index file is added,
Can be obtained by the timestamp of pausing operation.
Step 103, when client receives play operation, time shift duration and time of the client according to play operation
Stab to server and send direct broadcast time-shift request, and the second index file returned according to server parses and plays live video.
And work as user and complete after play operation, determining the time shift duration of user live broadcast time shift operation, time shift duration is then visitor
Family end is converted into time value according to the progress bar length of currently playing video, then can obtain direct broadcast time-shift operation when
Move duration.
According to above-mentioned timestamp and the determination method of time shift duration, timestamp is added with time shift duration, can be obtained
The time shift moment of live operation, client determines the time shift moment of live operation according to specific user live broadcast time shift operation, should
The absolute time synchronous with server side after time shift moment time shift operation, sends out when the direct broadcast time-shift for carrying the time shift moment is asked
Deliver to server.
In specific application scenarios, after server is received asks from the direct broadcast time-shift that client sends, typically
The time shifting request is all the URL request with timing node, and server obtains the time shift moment of the live operation for wherein carrying, obtains
The time shift moment corresponding video slicing of body storage is taken from, the second index file is generated according to corresponding video, by the second institute
Index file is sent to client.
In a preferred embodiment, when user is carried out continuously direct broadcast time-shift to be operated, for example, carry out within the extremely short time
Twice during direct broadcast time-shift, now server have received the request of direct broadcast time-shift twice of client transmission, and two ropes are generated respectively
Quotation part, in order to be ensured of the corresponding index file of accurate time shift operation result, client need to the index file when
Between label carry out matching confirmation, the solution of file is indexed if time tag is consistent with the time shift moment that direct broadcast time-shift is operated
Analysis, and carry out the download broadcasting of video slicing.
In the preferred embodiment of the application, client according to the second index file for receiving, to second index file
Parsed, the label in the second index file is judged is consistent with the time shift moment in current live time shift operation, then download
Corresponding video slicing is directly played out, when in the label in judging the second index file with current live time shift operation when
The shifting moment is inconsistent, does not carry out corresponding video slicing download, waits next index file to be received.
In specific application scenarios, as described in step 101, the direct broadcast time-shift operation of user during net cast
It is divided into rollback, suspends two kinds, and during for suspending, a length of 0 during time shift, if being directly downloaded as rollback corresponding
Video slicing is played out, wherein the video slicing downloaded before carrying out is abandoned, causes re-downloading for client, sacrificial
Domestic animal fractional bandwidth simultaneously causes the regular hour to postpone and certain memory space reads and postpones, and have impact on Consumer's Experience,
In the preferred embodiment of the application, user live broadcast time shift operation is made a distinction in server end, carried out to one in client
In the downloading process of the corresponding video slicing of index file, what is stored in memorizer is video slicing, and each video slicing has
The serial number of itself, is arranged in order sequentially in time, and the serial number of video slicing is cached in client-cache device,
The direct broadcast time-shift of server receive user is asked, and the operation that the time shift moment in direct broadcast time-shift request judges user and carries out is
Suspend or rollback, and generate flag bit, be filled with the index file for generating, if specially user carries out direct broadcast time-shift
A length of 0 during time shift in operation, to suspend, then the flag bit is 0 for instant direct broadcast time-shift operation, if time shift duration is not 0, i.e., directly
Operation is broadcast for rollback, then the flag bit is 1.
Below according to the difference of the type of direct broadcast time-shift operation, specifically there are following two situations：
Situation one, client is received after the second index file, and the second index file is parsed, if flag bit is 0,
It is pausing operation then to identify the direct broadcast time-shift operation, is continued to video point according to the serial number of the video slicing stored in buffer
Piece is downloaded, and keeps the seriality of video slicing in client.
Situation two, after client receives the second index file, if flag bit is 1, identify direct broadcast time-shift operation
For rollback operation, the serial number of the video slicing in the video slicing and buffer stored in memorizer is emptied, to the second rope
Quotation part is parsed, and directly carries out the download and broadcasting of brand-new video slicing.
As can be seen here, 0 delay in live pause operation is realized in the preferred embodiment of the application.
In specific application scenarios, the fluctuation or network failure due to real network can produce the interruption of Living Network,
In existing technology application, network recovery can directly carry out the broadcasting of current time, but can cause middle one section of video
Interrupt, produce video and jump the phenomenon broadcast, the experience of user can be affected, thus, in the preferred embodiment of the application, when live net
Network occur in have no progeny again reply after, and the Living Network break period be less than preset time threshold when, server is to client
Broken string configured information is sent, is embodied in, client is between the two adjacent video burst URL request sent to server
Time interval more than default very first time threshold value and less than the second time threshold when, it is straight that server judges to be connected with client
Broadcast network and there occurs that network interrupts, then server sends broken string configured information to client, includes in the broken string configured information
The suspension time of client and the time is reconnected, suspension time is the time that client stops foradownloaded video burst, when reconnecting
Between restart foradownloaded video burst for client time.
According to technical thought same as described above, the user end to server reconnected after suspension is asked into asking for video slicing
Ask and regard a direct broadcast time-shift request as, the time shift moment therein is the suspension moment of client, in order to eliminate client with service
The time delay at device end, using the time difference between suspension time and the time of reconnecting, the time difference is considered as time shift duration, when
Between skew for the buffered corresponding file video slicing of the first index before user's suspension quantity and each video slicing
Duration, then the suspension moment is the time difference between suspension time and the time of reconnecting plus the video slicing duration downloaded
Time migration, client generates direct broadcast time-shift request, the wherein request after the suspension configured information for receiving server transmission
In carry the suspension moment, suspension moment of the server in the direct broadcast time-shift request for receiving generates the 3rd index file,
Client is downloaded corresponding video slicing and is played out according to the 3rd index file for receiving, and in the process, needs
It is 0 that bright is flag bit.
It is pausing operation and broadcast by the direct broadcast time-shift division of operations of user customer by the technical scheme of application invention
Put operation, client obtains the time tag of current the first index file of parsing of client according to pausing operation, and with the
The playing duration of the corresponding video slicing of one index file, client determines according to time tag and playing duration to be suspended
Timestamp of the operation in live video, when client receives play operation, according to the time shift duration of direct broadcast time-shift operation with
And timestamp sends direct broadcast time-shift request to server, and the second index file returned according to server is parsed and plays live
Live video in network.Reducing when user watches live carries out the lagging feeling of broadcasting pictures and broadcasting after direct broadcast time-shift operation
The picture that delay is caused is discontinuous, improves Consumer's Experience.
In order to the technological thought of the present invention is expanded on further, in conjunction with specific application scenarios, the technical side to the present invention
Case is illustrated,
Based on HLS protocol it is live in, client plays direct broadcast band using uniform resource position mark URL, obtain
Playlist m3u8 files, general user can carry out two kinds of operations, time shift or time-out, below first to when user is to current live
When carrying out pausing operation, a kind of schematic flow sheet of live pause method of the application specific embodiment proposition is illustrated in figure 2,
Comprise the following steps that：
S201, when user occurs pausing operation, current player enters halted state；
S202, player records current time out stamp, and the value of the play sequence number of current cache；
S203, when user carries out continuation play operation, player enters as entered during broadcast state from halted state, player
The time out of record is issued server；
S204, server remakes m3u8 files according to the time out stamp for receiving, and the temporal information of the m3u8 is
Time out, by the m3u8 files client is handed down to；
S205, the timestamp of m3u8 files that client parsing is received, and according to the value of the serial number of caching continuing
Download, play out.
S206, if player status were introduced into always halted state, player then keeps playing newest video point
Piece.
Wherein, the method for the timestamp that client is obtained is as follows when calculating live pause：
1, the label #EXT-X-PROGRAM-DATE-TIME values in client parsing m3u8 files, and when being converted to unix
Between stab；
2, client calculates the video slicing number N played in current m3u8 files, and the duration of each burst
Value；
3, calculate the timestamp of the video pictures that active client is being played using formula.
As shown in Figure 2 a, it is the status display schematic diagram of broadcasting video slicing in player, is said based on the figure
Burst number N=3 that is bright, wherein having played in the current m3u8 files of client, the duration #EXTINF of wherein burst are respectively 5
Second, 6 seconds, 7 seconds, b=(5+6+7=18) seconds, the timestamp of time-out was a=2016-07-04T13:40:19Z, the time of time-out
Stamp result of calculation is c=a+b=13:40:19Z+18 second=13:40:37Z.
By taking Fig. 2 b as an example, time out A=#EXT-X-PROGRAM-DATE-TIME, the burst B=10 seconds, burst number N=
7, time out stamp=A+7*B.
Processing method when to be more than user carry out pausing operation when watching live, with go down when user carry out F.F. or
The processing method during time shift operations such as rollback is illustrated, as shown in figure 3, for the application specific embodiment propose it is a kind of live
The schematic flow sheet of time-shifting method, the method is specifically included：
S301, when user carries out progress bar to move, player enters halted state by broadcast state；
S302, player records current time out stamp, and the value of the play sequence number of current cache；
Specifically, when user is when the operation of progress bar time shift is made during live, client is literary according to current m3u8
The time shift quantity of time tag and chip in part is calculating correct time point, and player stops downloading new point
Piece, and the buffered slicing sequence number in current buffer the insides is recorded, now flag bit istimeshift=true, objective
Absolute time after the timestamp of lead record is to obtain time shift when family end adds according to the length of progress bar.
S303, when user enters broadcast state from halted state, by the time out stamp sending value server of record；
Specifically, the timestamp is beamed back the new m3u8 files of server request by client again after timestamp is obtained
Play out.
S304, server remakes m3u8 files according to the timestamp sent from client for receiving, and issues
To client；
Specifically, server, according to the time point, re-issues new m3u8 after the URL request for receiving the timestamp
File is to client.
In this step, server is needed to return the m3u8 files of a timestamp with unix, for example, a URL is such as
Under：
“http://hls.test.live/Channel (name=ch0097, startTime=
14646889450000000, i stimeshift=false)/index.m3u8 "
Wherein, player needs the state of field istimeshift in the m3u8 file names of detection parsing, Ran Hougen
Decide whether that player will be played out from first burst again according to this state.
S305, client parses the timestamp, and is entered carrying out the download of m3u8 according to the value of the serial number of caching
Row distribution is played.
S306, if flag bit istimeshift=false, directly plays newest burst.
Additionally, in the specific embodiment of the application, be also directed to it is live during suspension reconnect there is provided solution,
After suspension, when reconnect, a playlist can be re-issued, be exemplified below：As shown in figure 4, being the application
The playlist proposed in specific embodiment, includes a new tag label in the list：EXT-X-DISCONTINUITY, comes
