Description
Technical field
The present invention relates to one kind in internet (Internet) VOD system Novel multimedia tissue, storage and transmission
Method, more specifically, being related to a kind of scalable tissue of the flexible and efficient multimedia based on user's program request, storage and transmission side
Method.
Background technology
With the fast development of multimedia technology, there is explosive surge in multimedia content in internet, especially high
Extensively and profoundly, multimedia service highlights further to the pressure that network bandwidth is brought for clarity, high-resolution video business.Simultaneously
The difference of user personalized interest and the time variation of Network status, the feature of gathering is presented in multimedia service of today, more
The trend of fragmentation is presented in media content.Existing multi-media protocol only focuses on the complete of in network transmission process data mostly
Whole property and safety ensure the quality of multimedia service by ensureing the quality (QoS) of network, however whole to multimedia content
It closes and but seldom considers, the subjective satisfaction of user is also contemplated for very few.
Some current multi-media protocols are substantially the transmission and presentation that data are described and controlled by signaling information, still
It is not involved with multimedia content tissue rank, and does not account for Content Organizing and storage, the matching of transmission and entire more matchmakers
System is united data-optimized.Although caused by this way as a result, multimedia making side has made the unified complete programs of content,
By post-production such as editings, former program is divided into different editions by program emission side and provider, between each version all
Independently of each other, become an individual media content.Surface seems to enrich programme content in this way, actually destroys entire
The ecological environment of media system generates a large amount of duplicate data.These data have not only broken up the natural association system of media content,
It is unfavorable for the management of media content, increases carrying cost, causes resource and greatly waste, and content is identical in logic
Data cell needs repeatedly to repeat to transmit in a network, greatly reduces the efficiency of data transmission.Meanwhile in different editions program
Holding being individually present for redundancy makes originally abundant media resource become too fat to move mixed and disorderly, increases the difficulty of digital media content supervision
Therefore the media content of degree, many pirate infringements also more easily enters Digital Media market, cause program provider and consumption
The damage of person's interests.
On the other hand, media resource is rich in the burden for also increasing customer consumption Digital Media to a certain degree, uses
It family must selection of more energy for media consumption.Traditional method is that content supplier provides abundant media program such as
Various types of movie resources, but these programs are typically all full version, user generally can only program request certain full releases
Media program is consumed.Under such circumstances, it is needed to multiple sections if user thinks the program that selection viewing is liked oneself
Mesh carries out preview, and based on the inefficiency of mechanism data buffering, need user to wait for for a long time, user experience is very poor
Cake.
Better method is that former program is only logically divided into different editions by program emission side and provider, due to
The extensive use of media content fragmentation unit, former program are still physically the natural entirety of unification.It is taken in media content
The full release of storage media is only needed on business device, while corresponding signaling file being provided and is described corresponding to different media versions
Data cell.User is according to the media data of oneself demand program request related versions in this way, and server is according to media in signaling information
The mapping of version and data cell only transmits corresponding data to user.For example, user merely desires to preview some film once, he only needs
The link of program request preview versions, the cinematic data unit that server only transmits Preview Release is wanted to decode and present, user to client
The buffering of entire movie contents is withouted waiting for, better user experience can be obtained.Its difficulty is：System is difficult to know not
With the correspondence of media units between version, and lack relevant signaling mechanism guidance；Each media may have multiple
How version different in size distinguishes and manage to these versions, be also a problem to be solved.

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 domain.
Nowadays, video content amount is presented explosive growth, people's governable time also increasingly fragmentation.When user connects
When contacting a series of new videos, no longer it is often that its complete content is watched in direct program request, and is desirable to preview first these videos,
Then liked according to user itself and discretionary time determined which video is selected to watch at that time, if viewing all regards
Frequency content.
For this problem, can effective solution by the following method, improve user experience.Content supplier regards in making
Complete video content is uniformly completed when frequency, while using the importance and correlation degree of labeling method foundation content to therein
Segment is classified, so as to generate the video of different editions.Certainly, it should provide and be classified relevant version at presentation interface
This information, to facilitate user to carry out content selection consumption.When user watches, selective preview can be carried out according to these versions
And broadcasting, rather than the random selection of blindness.
By taking video content as an example, content production quotient only needs to be performed the programme content of complete set, then publisher can
Video is divided into multiple versions by the version management of content classification, it is supplied to media service provider.First version regards
Frequently it is Preview Release, duration 5 minutes, content only includes the excellent picture in video；Second version video is editing version, duration 30
Minute, content only includes the storyline and important scenes of video；Third version video is full version, and duration 120 minutes is interior
Appearance includes the complete story plot of video；4th version is strengthening version, and duration 150 minutes, the inside includes removing complete story
Expansion content, such as behind-the-scene footage except plot etc..
Below by taking MPEG-DASH (Dynamic Adaptive Streaming over HTTP) standard as an example, in introduction
Hold the version management mechanism of classification.Certainly, this mechanism is not limited to DASH standards, can also be applied to other standards and scheme.
DASH full name are the dynamic self-adapting stream based on HTTP, are formulated by international standard group MPEG, can by media by http protocol,
Content distribution is carried out in a manner of adaptive, gradual, download or stream, is supported under heterogeneous networks situation, a variety of different performances
Terminal on adaptive media consumption.DASH has a variety of stripping strategies on Content Organizing, and has corresponding signaling text
Part indicates its fragment details, it is contemplated that versatility is described respectively below as both of which.
Pattern 1:
It generates and the relevant differentiation MPD file of version
, can be according to four versions in above-mentioned video frequency program when generating DASH segment, generation and content classification
Corresponding MPD (Media Presentation Description) file.It is simple clear to describe, only write out in MPD
This description situations of segment list, other are as similar such as segment template situation processing modes.
According to the corresponding segment lists of four versions in above-mentioned video frequency program, as shown in Figure 1, generating these
When segment, the MPD file of four matching content versions is automatically generated.Wherein MPD elements increase@scaleID attributes, the category
Property define this MPD file description content classification rank, it is as shown in the table that content classification version corresponds to table.In addition
Segment lists in Representation elements in SegmentList daughter elements are no longer simple whole fragment lists,
And correspond to the specific fragment list of MPD scaleID.
| Version | Preview Release | Editing version | Full version | Strengthening version |
| scaleID | 0 | 1 | 2 | 3 |
As shown in Fig. 2, entirely the frame diagram and the original frames of DASH of classification mechanism are almost the same, in media preparation stage matchmaker
The generting machanism of body fragment (segment) remains unchanged, and is generated corresponding to 4 MPD files of different classification versions.
DASH clients, user is according to the video contents of the requirement request different editions of oneself, it is only necessary to the relevant MPD of server transport
File asks corresponding media slicing content to server again after client parsing.
For example, when user selects playblast version movie program, server sends the MPD texts that MPD@scaleID are 0
Part, the fragment after client parsing in request Representation elements listed by SegmentList daughter elements, i.e.,
channel1init.mp4、channel11.m4s、channel14.m4s、channel17.m4s、channel19.m4s.This
MPD document examples are as follows (newly plus parameter to be sascleID can have different new opplications)：
Pattern 2：
Original DASH mechanism is followed, a MPD file is only generated, wherein being added in Representation elements each
The@scaleID attributes of fragment
When generating DASH segment, can be distinguished according to four kinds of content classification versions, the instruction of differentiation is same
It is presented in the MPD tables of Shi Shengcheng.It is simple clear to describe, this description situations of segment list in MPD have only been write out, other
As segment template situation processing modes are similar.
According to the corresponding segment lists of four versions in above-mentioned video frequency program, as shown in Figure 1, generating these
When segment, each segment in the SegmentList daughter elements of the Representation elements of MPD file is carried
For@scaleID attributes, the attribute labeling using this segment minimum version rank.Content classification version corresponds to table and mould
Formula 1 is consistent.Such as segment：The@scaleID of channel13.m4s are 2, then this segment is only asked in user
It can just be consumed by server transport and client when full version video.
As shown in figure 3, entirely the system framework figure of classification mechanism and the original frames of DASH are almost the same, prepare rank in media
The generting machanism of section media slicing (segment) remains unchanged, while being also only generated there are one corresponding MPD file, but
The segment descriptions of MPD file increase@scaleID attributes, i.e. the version management label of content classification.In DASH clients,
User is according to the video content of the requirement request different editions of oneself, the unified MPD file of server transport, client parsing
According to the network state of oneself, equipment performance and the version of request situation after MPD, corresponding media point are asked to server
Piece content.
For example, when user selects to play full version movie program, server sends unified MPD file, client solution
@scaleID attribute values after analysis in request Representation elements listed by SegmentList daughter elements are less than or equal to
2 media slicing, i.e. channel1init.mp4, channel11.m4s, channel12.m4s, channel13.m4s,
channel14.m4s、channel15.m4s、channel16.m4s、channel17.m4s、channel18.m4s、
Channel19.m4s, channel110.m4s, server send these fragment contents, are decoded by client and be presented to the user.
This MPD document examples is as follows：
The present invention is a kind of flexible and efficient scalable tissue in internetworking point broadcast system, storage and the method for transmission,
To increase the media content flexible organization mechanism that existing multi-media protocol lacks, solves the transmission of existing multimedia system
The problem of efficiency is low, storage resource wastes, poor user experience.
Specific embodiments of the present invention are described above.It is to be appreciated that the invention is not limited in 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 the substantive content of the present invention.
