Description
Technical field
The present invention relates to communication technical field, particularly to a kind of method for synchronizing time.The present invention also relates to one
Client.
Background technology
Net cast refers to utilize the Internet and stream media technology to carry out live, and video is because having merged image, word, sound
Etc. abundant element, excellent both in sound and shape, excellent, it is increasingly becoming the main flow expression way of the Internet.Video is by true, lively
Propagate, build strong presence, attract eyeball, reach with deep impression, remember lasting communication effect.Video live broadcast service
Developing on the basis of VOD service, similar with VOD service, in video live broadcast service, all of program is all
To store in the server with the form of files in stream media, server after receiving the live request coming from client,
Files in stream media is sent to client by network, so that client resolves and to user's exhibition at the files in stream media that will receive
Show.
In order to improve Consumer's Experience, for the client of video live broadcast service while showing live video to user also
Can configure and show EPG (Electronic Program Guide, electronic program list) information.EPG Main Function is client
User's programme information is informed in end display, (such as program schedule, the programm name etc. being currently played), in the process,
Client is based on what EPG information was carried out showing by self time (system time or the APP in order to net cast).Citing
For, if there being two programs of A and B in the EPG information of server end, and according to the layout of program, program A ties at 1:00:00
Bundle, program B starts at 1:00:00, then client is by when the system time of self arrives 1:00:00, by server now
The files in stream media of the program B sent is play to user, displays to the user that currently playing program is B according to EPG information simultaneously.
According to above procedure it can be seen that time synchronized between client with server consistent be very important, if
Time synchronized between client and server there occurs deviation, it will user live brings bad experience, the most directly
The impact program that to be the program watched of user show with EPG in current time, have deviation.Illustrate with previous example,
If faster than the time of video data server 1 minute of the time of client, according to EPG information, at client time 1:00:01
Should show that the program being currently played is B during the second, and actually at this moment video data server is given to the video of client
Data are still program A.Thus produce error message, thus bring bad experience to the use of user.
In order to ensure time synchronized in prior art, following two mode is usually taken client is entered with video server
Row time synchronized, both modes can solve time synchronization problem, but inventor sends out during realizing the present invention
Existing, all there is respective shortcoming in aforesaid way:
(1) NTP (Network Time Protocol, NTP) synchronizes
NTP is used to a kind of agreement making synchronize each computer time in network, and it can make client regard it
Frequently server or clock source carry out time synchronized, and under which, client needs to obtain temporal information by ntp server, and then
Realization synchronizes, so that the time of the seen video frequency program of user and the time consistency of server.
Owing to which needs client to obtain temporal information to third-party server, and client is servicing from NTP
The interval that device obtains temporal information is the longest, thus causes the time error of client and video data server through longer
Time interval after constantly become big, have influence on the viewing experience of user.
(2) access interface synchronizes
In this scenario, technical staff needs the prior software to video data server and hardware to carry out configuration change
More so that the video server after configuration change provides an access being exclusively used in the acquisition video server time to connect to client
Mouthful, client obtains, by this interface of timer access, the time that video server is current, thus realizes the real-time synchronization of time.Should
Mode is in addition to needs are separately provided the access interface confession client acquisition time on video server, and video server
Need the time needing simultaneously to respond each client during providing video data stream to client in subsequent process
Obtain request transmission time information, bring extra access pressure and potential safety hazard to video server.
As can be seen here, how to make server interact under premise without extra and client, current offer is being provided and regards
Frequently the time error between client and the video server of live broadcast service, improves the degree of accuracy showing the time in client, from
And provide the user more preferable experience, become the technical problem that those skilled in the art are urgently to be resolved hurrily.
Summary of the invention

Detailed description of the invention
As stated in the Background Art, prior art needs between client and video server in video living transmission system
Time error controls in a less scope as far as possible, brings obvious shadow the most just will not to the net cast process of user
Ring, thus improve good experience to user.But, same before and after being currently based on the time synchronizing method of ntp server
Step time interval is long, it is impossible to is controlled the time error scope between client and video server, causes user to exist
During using video live broadcast service by client, the EPG information of the showed user of client is broadcast with client
The video code flow put there may be inconsistent situation, thus experience to the net cast of user and bring obvious bad experience.
And if timing acquisition of information flow process is set between client and video server, except technical staff need right
Existing screen data server carries out beyond configuration change, and the performance of concurrent video data server also will undertake and come from
The extra access burden of client.
As it is shown in figure 1, carry out HLS (HTTP Live for prior art is carried the client of Android system
