In being embodied as, transcoding cluster may include multiple transcoding modules, by multiple transcoding modules to needing transcoding to encapsulate
Program request material carry out transcoding encapsulation, it is ensured that transcoding encapsulation be efficiently rapidly completed.And the TS fragments of generation are stored in
In data buffer storage, the TS fragments reusable of the production reviews broadcasting in user or user plays again.
In enforcement, transcoding cluster carries out transcoding encapsulation generation TS fragments, the TS to program request material to set duration interval
Timestamp is carried in fragment, the timestamp is to identify the setting duration interval adopted when the program request material transcoding is encapsulated
And relative position.
For example, one section when a length of 8 points of program request materials of 56 seconds, user is carried out after program request by client, with progress during 8s
The encapsulation of row transcoding generates a TS fragment, needs transcoding to encapsulate 67 TS fragments, and when normal play was to 40 seconds, user carries out redirecting behaviour
Make, jumping to 4 points of video carries out program request in 0 second, now determine the corresponding TS fragments that are not stored with data buffer storage, trigger transcoding
Cluster starts transcoding module carries out fast transcoding encapsulation generation TS fragments, and the TS fragments that transcoding encapsulation is generated carry timestamp, should
8 seconds durations of the TS fragments correspondence program request material relative position for identifying the generation are included in timestamp, for example, video is jumped to
The timestamp of TS fragments that generates of 4 point of 0 correspondence in identify the generation TS fragments correspondence program request material 4 points 0 second to 4 point 8
8 seconds durations, certainly, jump in the range of 4 points 0 second to 4 point 8 of video, such as user jumps to 4 points 2 seconds, institute's transcoding encapsulation
The TS fragments of generation correspond to 4 points of positions of 0 second to 4 point 8 of program request material.Each is generated by the encapsulation of transcoding cluster transcoding
TS fragments all carry timestamp, and are stored in data buffer storage, it is determined that the corresponding TS of jump location that is stored with data buffer storage
During fragment, it is sent to subscription client and plays out.When user carries out reviewing operation, 4 points of video are carried out again for 0 second
The last operation of program request, it may be determined that the TS fragments of correspondence position have been stored in data buffer storage, i.e. user is by the 4 of program request material
The position of point 0 second to 4 point 8 carries out transcoding and is packaged into TS fragments, and is stored in data buffer storage, you can directly send out the TS fragments
Give subscription client to play out.
And when user carry out program request again or review to 4 points operate before within 0 second when, progress during due to employing setting
Row transcoding is encapsulated, and now only needs to carry out the video material of 4 points of non-transcoding encapsulation before in 0 second transcoding encapsulation generation TS fragments,
For the TS fragments reusable of 4 points of transcoding encapsulation afterwards in 0 second is in this operation program request, therefore, provide in the embodiment of the present invention

Generation m3u (8) file in file is filled into according to m3u (8) rule, and the file for generating m3u (8) is returned to into client.
Client is received after m3u (8) file, continues to ask the TS fragments inside m3u (8) file, receives TS fragments
After request, determine and whether have in data buffer storage corresponding TS fragments, when it is determined that be stored with data buffer storage TS fragments when, by TS fragments
It is sent to client；When it is determined that be not stored with data buffer storage the TS fragments when, send transcoding request to transcoding cluster.
Transcoding cluster is received after transcoding request, and one or more transcoding modules are started while entering according to program request material duration
Row transcoding is encapsulated, and each transcoding module carries out transcoding encapsulation generation TS clip files, transcoding to video material to set duration interval
TS clip files after encapsulation carry timestamp, and store in data buffer storage.
In addition, if when user carries out Seek operations, asking the TS fragments specified inside m3u (8) file, finger is received
After determining TS fragment requests, determine and whether have in data buffer storage corresponding specified TS fragments, when it is determined that the finger that is stored with data buffer storage
When determining TS fragments, the TS fragments are sent to into client；When it is determined that be not stored with data buffer storage the specified TS fragments when, send out
Transcoding request is sent to transcoding cluster.
Transcoding cluster is received after transcoding request, and one or more transcoding modules are started while entering according to program request material duration

Assume that a length of 100 minutes during program request material, subscription client has been received by m3u (8) file, continue to ask m3u (8)
TS fragments inside file, now, determining when be not stored with data buffer storage TS fragments, send transcoding request to transcoding cluster,
Transcoding cluster is received after transcoding request, and start multiple transcoding modules according to program request material duration carries out transcoding encapsulation simultaneously, respectively
Transcoding module is spaced 8 seconds with setting duration, from 0 second, transcoding encapsulation in 0 second of program request material to 8 seconds is generated into a TS fragment,
Transcoding encapsulation in 8 seconds to 16 seconds generates a TS fragment, and by that analogy, each transcoding module is spaced to program request material with setting duration
Relative position carry out transcoding encapsulation and generate correspondence TS fragments, and be stored in data buffer storage.Due to transcoding cluster enable it is many
Individual transcoding module carries out transcoding encapsulation simultaneously, improves the formation efficiency of TS fragments, greatly shortens the stand-by period of user.
Assume now, user watch to program request material 5 points 21 seconds, and actual transcoding encapsulate completed the 0 of program request material
By 40 minutes, user carried out skip operation, and jump to video 56 points are watched for 12 seconds, it is determined that not storing in data buffer storage
There are TS fragments that program request material 56 point specifies for 12 seconds (56 point 8 of TS fragments correspondence program request material of the generation to be identified in timestamp
TS fragment of the second to 56 points of 8 seconds durations of 16 seconds) when, transcoding request is sent to transcoding cluster.
Transcoding cluster is received after transcoding request, and start multiple transcoding modules according to program request material duration carries out transcoding simultaneously
Encapsulation, each transcoding module is spaced 8 seconds with setting duration, from 56 points of the specified corresponding video material of TS fragments 8 seconds, by point
56 points of 8 seconds to the 56 points 16 seconds transcodings encapsulation for broadcasting material generates a TS fragment, 56 points of 16 seconds to 56 points 24 seconds transcodings encapsulation lifes
Into a TS fragment, by that analogy, each transcoding module carries out transcoding to set duration interval to the relative position of program request material
Encapsulation generates correspondence TS fragments, and is stored in data buffer storage.Also due to transcoding cluster enables multiple transcoding modules simultaneously
Transcoding encapsulation is carried out, the formation efficiency of TS fragments is improved, the stand-by period of user is greatly shortened.
Assume now, user watch to program request material 61 points 33 seconds, and actual transcoding encapsulate completed the 0 of program request material
To 40 minutes and 56 points 8 seconds to 48 seconds 90 minutes, user carries out reviewing operation again, reviews to 48 points of video and is seen for 6 seconds
See, it is determined that the TS fragments that the program request material 48 point that is not stored with data buffer storage is specified for 6 seconds (identify the TS of the generation in timestamp
The TS fragments of 48 points of 8 seconds durations of 0 second to 48 points and 8 seconds of fragment correspondence program request material) when, transcoding request is sent to transcoding cluster.
Transcoding cluster is received after transcoding request, and start multiple transcoding modules according to program request material duration carries out transcoding simultaneously
