The segmented mode of a length of 10 minutes, 20 minutes and 30 minutes split after video segment.When above-mentioned server receives end
After first load request at end, server can search the video segment that segmentation duration is not less than 15 minutes, after finding, clothes
It is engaged in that device can be split the segmented mode according to a length of 20 minutes or 30 minutes during segmentation and corresponds to video to be loaded
The target video fragment of fragment feeds back to terminal.
In order to clear, video is split as the process of the video segment of different length by server in advance, will be with clothes
Business device angle describes to describe in detail again during the program.
S105, the network address of the target video fragment of the reception server feedback, and then the target video fragment is entered
Row loading and broadcasting.
Specifically, after the network address of video segment to be loaded is fed back to terminal by server in S104, this area skill
Art personnel are it is understood that the correspondingly received network address of terminal, and then from the network address by video segment to be loaded
Download, so as to be played out to it.
In actual applications, user disposably be able to not may be just accurately positioned at required video, at this moment may be
In one specific period, a series of frequent operations are often carried out, in order to further improve the speed of video loading, this hair
The method of bright embodiment can also comprise the following steps：
Obtain operation of the user in the first special time period to the video；
The actual frequent operation angle value of user is determined, wherein, the frequent operation angle value is that user is special described first
The number of operations fixed time in section；
By the actual frequent operation angle value compared with default frequent operation angle value；
When the actual frequent operation angle value is not less than the default frequent operation angle value, set for current video
Add less than the target resolution of the true resolution of the current video, and to second of server transmission comprising target resolution
Request is carried, to cause server after second load request is received, there will be the target resolution and be treated with described
The network address of the corresponding target video fragment of the content of the video segment of loading feeds back to the terminal.
So, the network address of the target video fragment of terminal can the reception server feedback, and then to the target
Video segment is loaded and played.
Specifically, video just commenced play out or playing process in, user may to video carry out it is a series of frequently behaviour
Make, now terminal accordingly obtain user in the first special time period to a series of frequent operations of video after, system can be passed through
The number of this sequence of operations is counted to determine the actual frequent operation angle value of user, wherein, the frequent operation angle value can profit
Represented with number of operations of the user in the first special time period.Then by the actual frequent operation angle value and default behaviour
Make frequent angle value to be compared, when the frequent operation angle value of reality is not less than the default frequent operation angle value, illustrate user
Number of operations already exceed limitation, certain obstruction may be caused to the loading of video, at this moment terminal is automatically to work as forward sight
Frequency is set lower than the target resolution of the true resolution of the current video, and then sends the second load request to server,
Second load request is with carrying the network of oriented to be loaded video segment of the server request feedback with target resolution
The facility information of the solicited message of location and the terminal, such as：Device number, MAC (physics) address etc..Then so that server connects
, will be with the target resolution and corresponding with the content of the video segment to be loaded after receiving second load request
The network address of target video fragment feed back to the terminal, terminal is carried out using the network address to the target video fragment
Loading, and then target video fragment is played out.After a period of time, detect that the number of operations of user is less than certain threshold value
When, the operation of user will not load to video to be impacted, and at this moment can be that current video sets the reality for being higher than the current video
The target resolution of border resolution ratio, so that user is capable of the clear video of viewing of smoothness.
For example, the first special time period is arranged to 10 seconds, default frequent operation angle value is 3 times, and user is 30
Second in actual frequent operation angle value be 4 times, each F.F. video segment length be respectively 5 minutes, 6 minutes, 7 minutes and
8 minutes, according to the method for the embodiment of the present invention, it is assumed that terminal to server sends the first load request, and server is to terminal
The network address of transmission objectives video segment, and terminal is loaded according to network address, current video resolution ratio is
1080P, after user clicks on the 4th forwarding operation, it is clear that actual frequent operation angle value is more than default frequent operation degree
Value, terminal reduce resolution requirement, it is assumed that are 720P, the second load request is sent to server so that server response should
Second load request, it is to be understood that server needs the time to terminal transmission target video fragment data amount, typically
For, the time required to above-mentioned first special time period can be far smaller than the transmission of target video fragment data amount, therefore in server
After responding second load request, the target video fragment do not transmitted yet that resolution ratio is 720P can be transmitted, so passed
Defeated video segment data amount is reduced, and saves bandwidth so that loading velocity increase, user experience more preferably.
As known from the above, it can make the loading of video to be loaded more quick by way of adjusting resolution ratio, use
Family obtains an experience well between video readability and video fluency, when user's operation is excessively frequent, suitably
Video readability is sacrificed to make video smooth playing,, can under the premise of the smooth viewing of video is ensured when user's operation is less
With the high-resolution clear video pictures of use of selectivity, user's impression is improved.
Ideally, if network condition is preferable, no matter user carries out operation how often, video in special time
Loading is played all without being affected, but in practice, network condition does not often reach this perfect condition, therefore often
Need network bandwidth situation current under detection, then it is described when the actual frequent operation angle value is not less than the default behaviour
When making frequent angle value, the target resolution of the true resolution of the current video is set lower than for current video, including：
When the actual frequent operation angle value is not less than the default frequent operation angle value, current network band is detected
It is wide；
When the current network bandwidth is not more than default bandwidth value, the current video is set lower than for current video
True resolution target resolution.
Specifically, when above-mentioned actual frequent operation angle value is not less than default frequent operation angle value, can be first
Network bandwidth situation under the lower current state of detection, when network bandwidth is more than default bandwidth value, video smooth can enter
Row loading, terminal need not carry out unnecessary operation, but can be current video when network bandwidth is not more than default bandwidth value
It is set lower than the target resolution of the true resolution of the current video.
As known from the above, when network bandwidth is out of condition, i.e. when current network bandwidth is not more than default bandwidth value, be
Current video is set lower than the target resolution of the true resolution of the current video, because low resolution is than high-resolution pair
The data volume for the video answered is small, and the network bandwidth of occupancy is small, so in the case that network bandwidth is out of condition, reducing resolution ratio can
To reduce the probability of video cardton, user experiences more preferably.
In the embodiment of the present invention, terminal receives user and the forwarding operation of video is instructed；Referred to according to the forwarding operation of user
Order, determines video segment to be loaded, wherein, the video segment to be loaded is part or all of interior in the video
Hold；Build the first load request of the video segment to be loaded；First load request is sent to server, to cause
