Specific embodiment
The present invention is described in detail combined with specific embodiments below.Following embodiment will be helpful to the technology of this field
Personnel further understand the present invention, but the invention is not limited in any way.It should be pointed out that the ordinary skill of this field
For personnel, without departing from the inventive concept of the premise, various modifications and improvements can be made.These belong to the present invention
Protection scope.
Server provides the user with relevance by the way that the mapping table of media content and media description is transferred to user
The option of media content.User can request the different editions of identical content, or a certain media money of request according to their own needs
A variety of appearance forms such as the association content in source.In order to save storage resource, differentiation transmission is realized, same set of media resource is not
With including shared data cell in version.But existing system can not carry out the presentation time to the content of different editions
Control, may cause media play and the segment of vacancy occurs, influence user experience.Each data are provided using existing system
The Duration Information of unit, it is contemplated that the characteristic of different transmission networks, for example, VoD (Video on Demand) be according to
Family selection section object time determines the initial presentation time of media resource, and broadcasting with real-time live broadcast is then in the defined time
It is synchronous in each equipment to present, but there is still a need for the real-times considered the problems of in random access and real-time live broadcast.Therefore, this hair
Different personalized presentation timeline controlling mechanisms is introduced in bright by taking the transmission network in the case of three kinds as an example.
Using one: VoD
VoD service in, after user has selected some multimedia content, server responds the demand, according to
The version of family selection reads the duration of corresponding media data units, generates corresponding guidance and message file and signaling is presented
Information.
By taking the classification of identical content is presented as an example, to Mr. Yu's movie program, it is assumed that it is asset1.First version video
For scaled-down version film clips, duration 5 minutes, the inside only included the excellent picture in film；Second version video is shearing version, duration
30 minutes, the inside only included the important scene of photoplay plot；Third version video is full version, duration 120 minutes, inner
Face includes complete plot；4th version is extended edition, and duration 150 minutes, the inside included removing complete plot
Except expansion content, such as behind-the-scene footage, as shown in Figure 1.
Using two: broadcast program
In broadcast service, server transmits media data flow according to scheduled the rendition list.In view of user connects at random
Enter problem, relevant information carousel will be presented in server needs.User can be in access according to the current presentation received
Timeline starts to watch media content.Meanwhile switching viewing in real time according to indexs such as the state such as charge levels of viewing equipment
Mode, provide more preferably user experience in the case where adapting to equipment state.
By taking the ball match program by broadcast transmission as an example, when user watches ball match on the mobile apparatus, equipment need to be considered
Remaining capacity.When generating media data units, classified according to the importance of media data units, such as splendid moment and
Goal etc. camera lens is the different association contents of the program, assigns different marks respectively, as shown in Figure 2.The electricity of user
Situation is roughly divided into Full Charge Capacity, the grade of medium electricity and low battery.
When the remaining capacity of equipment reaches corresponding grade, then sending request accordingly, to server, server is cut automatically
Change hair video media content and complete audio content, and the synchronization of the time line traffic control media content according to transmission.?
In the case where translator unit video media content, the temporal information inside video data unit can not be parsed.Therefore, pass through parsing
The relevant signaling of timeline obtains temporal information accordingly, realizes that the program for adapting to status of equipment is presented.
Using three: real-time live broadcast
In the service of real-time live broadcast, media data is conveyed directly to client after recording processing, therefore to real-time
Requirement it is very high.In order to guarantee that the individual demand of the user in real-time live broadcast is also able to achieve, the association for media resource
Content, which requires to quickly generate independent timeline, to be controlled.
For example, most of user also wishes to watch programme content (such as by the service of multi-angle of view when watching real-time live broadcast
Shown in Fig. 3).Stablize real-time multi-angle of view service to save network bandwidth and provide, the content for servicing offer passes through broadcast
Net is transferred to user, the simultaneous transmission media resource relevant content presentation timeline information.Due to each association content
Total duration and comprising media data units the presentation time it is different, carried out so needing to generate the different timeline of more sets
Control is presented.
Media resource is divided into the independent media units that can be solved by the present invention, using the incidence relation of media units, according to use
The different video versions of family selection automatically generate corresponding presentation timeline.Therefore, presentation mechanism of the invention and existing skill
Art is compared to more flexible.
Some embodiments of the invention are described in detail below.
User when watching media content, tend not to it is all interested in whole section of programme content, may only in program
Some personage or some scene are interested.Smart media Transmission system can carry out the classification of different angle to media content, that is, beat
Upper different label provides possibility for the individual demand of user.When personalization is presented, the association content packet of different editions
Containing shared media data units, but presentation time of these data cells in each version is different, and therefore, it is necessary to be directed to
Each version generates different presentation timelines to control and play.
In the above example, the MPU in each version (media processing units) media data units
It is as shown in Figure 4 that the time is presented.Wherein, duri indicates the duration of i-th of MPU.As shown, in a media resource,
The presentation time of identical MPU is different.Therefore, independent timeline is required to refer to the different associated versions of same media resource
Lead presentation.
In order to guarantee the user experience in personalized service, to the difference of different media resource or same media resource
The content of version provides corresponding presentation timeline, enables media content according in timeline one by one presentation user's selection
Hold.The present invention is come by increasing new descriptor or increasing the signaling informations such as other tutorial messages such as message, table newly
It realizes the transmission that timeline is presented, and is introduced by taking following three kinds of schemes as an example.
Scheme one:
Using MPU timestamp descriptor defined in MMT.MPU is marked in the descriptor at one
The time is absolutely presented in corresponding label mpu_sequence_number and corresponding UTC in media resource；The descriptor's
Syntactic structure is as shown in the table.
Descriptor_tag-defines the label of the descriptor type.
Descriptor_length-defines the length of the descriptor.
Mpu_sequence_number-lists the label for all MPU for including in corresponding media resource, N in order
Indicate the number of MPU.
Mpu_presentation_time-lists all MPU that the corresponding media resource of the descriptor includes
The time is absolutely presented in UTC.
During transmission media content, according to the media content that user selects, its corresponding media data list is selected
First MPU parses its Duration Information duration.It is each to be associated with contents version institute if selecting the association content of media resource
The MPU that includes has repetition, i.e., same MPU may have the different absolute presentation time in different association contents versions, then take
Business device obtains the Duration Information of corresponding MPU according to the version that user selects.The media play time selected in conjunction with user
Or media play time as defined in system is calculated each by the duration of all MPU before cumulative specified MPU
Time, the mpu_presentation_time in as descriptor is absolutely presented in the corresponding UTC of MPU.
Some descriptive descriptor are defined in the signaling message of existing MMT protocol definition, such as
Therefore dependency descriptor and MPU_timestamp_descriptor can define an offer media content
With the corresponding descriptor that relevant temporal information is presented.There is asset_descriptors field in MP table, it can be with
Correlation descriptor is added in asset_descriptors as needed.It, can should when using multimedia service
Descriptor, which is added in asset_descriptors, realizes presentation.
But order program service is user-driven, needs to consider operation of the user in watching process, such as pause and fast
Into etc..It in this case, can not be correctly if the time is absolutely presented in the UTC that server only provides corresponding each MPU
Continue to play, needs server to regenerate and timeline information is presented is transmitted again, cause biggish computation burden and superfluous
Surplus also will cause certain delay and influence user experience.Time, that is, mpu_ is absolutely presented using UTC in broadcast service
Presentation_time is a kind of convenient and fast mode, because play time of the selected media content in direct broadcast service is
Fixed.User receives a certain media resource and selects its association service, while receiving corresponding MPU_timestamp_
Descriptor, the temporal information that the media data units foundation of the content of each associated section describes in son are at a fixed time
It is existing.
Scheme two:
Define MPU timestamp descriptor.According to the association content of same media resource and its corresponding MPU
Set define edit list, assign independent edit id to the association content of each version.It is described in descriptor
The mpu_sequence_number for all MPU for including in each edit list and corresponding presentation temporal information；It should
The syntactic structure of descriptor is as shown in the table.
Descriptor_tag-defines the label of the descriptor type.
Descriptor_length-defines the length of the descriptor.
Edit_list_number-defines the association content of media resource, and N1 indicates its number.
Edit_id-defines the label of each version of the association content of media resource.
Mpu_sequence_number-lists the label for all MPU for including in corresponding media resource, N in order
Indicate the number of MPU.
Mpu_presentation_time-lists all MPU that the corresponding media resource of the descriptor includes
The time is absolutely presented in UTC.
During transmission media content, according to the media content that user selects, the institute of the media resource selected
The UTC of relevant content is absolutely presented time mpu_presentation_time and writes in the descriptor (time acquisition
Mode is referring to scheme one).During consuming media content, server sends above-mentioned descriptor to visitor with signaling information
Family end.User selects the association content of a certain version, parses media data units therein according to its corresponding edit_id
MPU and corresponding absolute presentation time mpu_presentation_time, the timeline for generating corresponding version are presented to control.
The presentation time of the media content of each associated version, and personalized user can be more conveniently obtained by such method
Demand instructs to present by identical descriptor information, is more convenient for controlling.
Scheme three:
Described in the signaling, and by CI (Composition the duration of each MPU in some media resource
Information at the beginning of learning the media resource in), the time is absolutely presented in the UTC that each MPU can be calculated.
Descriptor_tag-defines the label of the descriptor type.
Descriptor_length-defines the length of the descriptor.
Mpu_sequence_number-lists the label for all MPU for including in corresponding media resource, N in order
Indicate the number of MPU.
The UTC that mpu_duration-lists all MPU that the corresponding media resource of the descriptor includes is absolute
The time is presented.
During transmission media content, according to the media content that user selects, its corresponding media data list is selected
First MPU parses its Duration Information duration, while generating guidance and information, i.e. the label mpu_ of MPU is presented
Sequence_number and corresponding duration information.
In view of a variety of different transmission network situations, such scheme can generate and packaged media data cell it is same
When, its corresponding duration duration information is obtained, therefore real-time demand can be better meet, can met in real time
The application demand of live streaming.Replaced by transmission duration information and the time is absolutely presented, enabled a client to more flexiblely
Self-organizing media content.Meanwhile in the business of broadband program request, user can also be supported to carry out input operation at any time, meet user
Individual demand.
Three of the above scheme can cover including multiple multi-media transmission systems such as broadband networks and radio network even heterogeneous network,
We can also be by being presented policy paper CI or the other positions of transmission signaling information are added and corresponding the time are presented
Personalized presentation service equally may be implemented in line.
During controlling presentation, since broadcast and real-time live broadcast service are since user's current turn-on time
It plays.In order to save the storage resource of bandwidth resources and client and calculate consumption, only write in above-mentioned descriptor
These two types of temporal informations (are referred to as correlation below by the presentation temporal information or duration information for entering the MPU not consumed also
Temporal information), without the correlation time of the corresponding all MPU of transmission media resource.In this manner, although increasing generation
The complexity of signaling information, but transmission network bandwidth and the limited computing capability of client is greatly saved.Further, since program request
Service be not present random access problems, therefore user start service when can transmit accordingly finite number MPU phase
Temporal information is closed, and transmits the correlation time information of subsequent MPU in time according to the viewing progress of user.For the stream for guaranteeing viewing
Smooth property, when needing to timely respond to the operation of user in viewing, the correlation time information of transmission updates and timeline is presented.
It is raw below as the description method of above scheme three more clearly to describe implementation proposed by the present invention
At MPU_presentation_descriptor, the personalized presentation TimeLine Mechanism in VoD service, citing description are constructed
One concrete implementation process:
As shown in figure 5, be introduced by taking above-mentioned scheme three as an example, provide that a kind of multimedia content personalization is presented when
Between line control method, this method process specifically:
When receiving end request VoD service, transmitting terminal will send signaling information, and receiving end passes through the PI_ judged in MPI table
Content_type_length_byte field receives MUR, CI and html file, while will be updated and generate local maintenance
MPU storing data library MySQL；When user requests scaled-down version video, receiving end is associated with the edit_ of media content by inquiry
List signaling information obtains the mark edit_id=00 of edit_list corresponding with scaled-down version video, media wherein included
The mpu_seq_number of unit is 1,9, the media content of the edit_id=00 of receiving end request at this time.Transmitting terminal analysis request
It obtains corresponding mpu_seq_number and parses media data units MPU and obtain its corresponding duration duration letter
Breath generates MPU_presentation_descriptor signaling.Receiving end receives corresponding signaling, according to MPU_
The absolute presentation time of each MPU is generated at the beginning of in presentation_descriptor and CI, the time is presented in maintenance
Line.Receiving media data, which is stored in, simultaneously locally plays to user, and updates local data base.When user then requests to shear
When version video, the edit_id=00U01 of version video is sheared.By the edit_list signaling and the local that check association media content
MPU existing for database, to the media resource of transmitting terminal request edit_id=01.Receiving end receive signaling and media data it
It parses afterwards and obtains the media data units mpu_seq_number in resource, and according to MPU_presentation_
Duration information in descriptor signaling recalculates the presentation time for the MPU that shearing version video is included, and update is in
Existing timeline.The MPU that mpu_seq_number is 4,6 is received simultaneously is stored into local.
It is heretofore described by taking MMT as an example, illustrate proposed solution, but these schemes equally can be used for
Other Document encapsulations, in Transmission system and agreement.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited to above-mentioned
Particular implementation, those skilled in the art can make various deformations or amendments within the scope of the claims, this not shadow
Ring substantive content of the invention.
