Illustrated in the following, implementing information popularization method provided in an embodiment of the present invention with reference to Fig. 3-1 pairs of transfer backstages.
Referring to an optional flow diagram of the information popularization method shown in Fig. 5, comprise the following steps：
Step 201, transfer backstage receives the mark for the media information that user side request plays and user side request plays
Promotion message mark.
As shown in figure 3-1, the player that operation plays online Media information in user side equipment (can also be to support media
The clients such as the browser that information plays), user selectes in the media information list for broadcasting that player is presented to be needed
The media information of broadcasting, it is possible to understand that ground, media information can be video format or audio format, such as choose that needs are watched one
Collect TV play, or the song for choosing needs to listen to.
After user chooses the media information such as video (TV programme) that needs play or audio (Online Music), play
It is directed toward with the data of acquisition request respective media information, address the address that device sends the media information that request plays to transfer backstage
The media letter being stored in media backstage or other databases (for example, being exclusively used in the content distributing network of media information)
Breath；Can alternatively, player can be asked to the mark of the other forms for the media information that the transmission request of transfer backstage plays
The data for obtaining respective media information are sought, are such as used for the sequence number of unique mark media information.
User side equipment has also run advertisement SDK, and player calls advertisement SDK in the process of running, and advertisement SDK is according to certainly
Whether the processing logical decision of body plays advertisement (such as bumper advertisements) when media information plays, as judged to need to play advertisement,
Then to advertisement background request advertisement, especially, if advertisement SKD has obtained the relevant information of advertisement (such as advertisement in advance
Address or sequence number), then the mark of the form such as address that can be based on advertisement or sequence number is to transfer background request advertisement.
For example, advertisement SDK carries out following decision-making：Whether first choice, detection user step in the client for playing media information
Record, if be not logged in, judgement needs to play advertisement；As user is in login status, then detects user and whether buy and uses
Exempt to play the service of advertisement, as user has bought the service, then judge that advertisement need not be played, otherwise, it is determined that needing to play
Advertisement.
Advertisement SDK can be obtained from advertisement backstage in advance when called to be needed (such as to meet in the advertisement that user side plays
Orient the advertisement of fixed condition) address or the form such as sequence number mark, and according to advertisement user side actual exposure feelings
The advertisement that condition decision requests play.
For example, according to the priority orders of advertisement, and in the exposed advertisement of user side, to transfer background request not
The advertisement of the limit priority of exposure.
Step 202, transfer backstage obtains the media information that needs to be encoded and described according to acquired mark
Promotion message.
Continue aforementioned exemplary, the address for the media information that transfer backstage is sent based on player or sequence number, Ke Yi
The media information that the database of media backstage or other forms (such as content distributing network) positioning user side request plays.
Certainly, it should be pointed out that transfer backstage is suitable for the live scene and program request scene of media information.For example, such as
It is preceding described, supporting the application of media information (such as recording TV program, film) that user chooses making to finish by player
In scene, media information can be the data on media backstage or other database purchases, such as in storage database in advance
The TV play having had been taken data, transfer backstage by user side return respective media information data realize media
The program request of information.
Or media information can be by being connected and obtaining real-time with media information collecting device (such as camera)
(such as concert scene) video data of collection site, when user side request plays the live media information, transfer backstage
The video data at scene can be equally returned to user side.
Step 203, transfer backstage encodes media information and promotion message respectively.
The data volume of digitized media information such as voice data and video data is very big, and larger data volume is net
The sensible factor of network transmission, therefore, it is necessary to carry out necessary compression to media information before network transmission is carried out to user side
Coding, reduces the pressure of network transmission, is corresponded to according to the data format of media information and is compressed coding.
In one embodiment, coding is compressed to the media information of video format using video compression algorithm, used
Audio compression algorithm is compressed coding to the media information of audio format；Similarly, using video compression algorithm to video lattice
The promotion message of formula is compressed coding, and coding is compressed to the promotion message of audio format using audio compression algorithm.
For example, combined using the compression algorithm of H.264 video compression algorithm+AAC audio compression algorithms.With using H.264
Exemplified by video compression algorithm is compressed coding to video data, pass through video coding layer (VCL, the Video of coding H.264
Coding Layer) and network abstract layer (NAL, Network Abstraction Layer) realize, video coding layer to regarding
Frequency is according to being encoded, including the content such as estimation, entropy coding, and the data volume after coding is able to reduce so as to adapt to network
Transmission.
Step 204, transfer backstage is corresponding encapsulates obtained coded data formation media information stream file and promotion message
Stream file.
, will be to media information in the video coding layer of coding H.264 still exemplified by using H.264 video compression algorithm
The data i.e. coded data obtained after coding are packaged to form media information stream file；Obtained after being encoded to promotion message
Data i.e. coded data be packaged to form promotion message stream file.By encapsulating obtained H.264 compressed encoding lattice
The stream file of formula has network adaptability, can easily be transmitted on the heterogeneous networks between user side and transfer platform.
In one embodiment, the encapsulation for coded data is adopted in such a way, in the track of the first format container
The coded data for filling the media information obtains the media information stream file, described in the track filling in the second format container
The coded data of promotion message obtains the promotion message stream file.Wherein, the first format container and the second format container can be with
For identical format container, such as MP4 format containers；It is of course also possible to be the container of different-format, such as the first format container
For MP4 format containers, the second format container is MKV format containers, or is FLV format containers.
Container Format is corresponding with stream file, such as MP4 forms.For a kind of format container, a variety of different rails can be included
Road, each track can be used for storing the information such as video data, voice data or text after compressed encoding.To include at the same time
Exemplified by the media information of media data and voice data, the effect of container is the video data and voice data after compressed encoding
It is placed on the different tracks of same stream file, addition information is convenient to be played back at the same time, and by coded data arrangement as compact as possible.
Usually, Container Format includes following three parts：
Header：The base attribute information such as tab file type, audio-video code stream.
Index：The information such as concordance list, video frame corresponding offset, size and timestamp.
Stream：Audio and video uncorrected data.
A typical structure schematic diagram of MP4 Container Formats is given in Fig. 6-1, is mainly made of box (box), MP4
Format container is a kind of container of nesting step by step.MP4 Container Formats are made of several box, and each box has type and length,
Different information or data can be filled.Box can be understood as data object block, other box can be included in some box,
This box is known as combining (contained) box.Four bytes (32) of the box beginnings of standard are box sizes (size), bag
Include box heads (header) and box bodies (body).Size followed by 32 be box types (type), be usually four words
Symbol, such as " ftyp ", " moov ", each box have the information that fixed form and needs are filled.Wherein ftyp box have and only
There is one, it is impossible to included by other box.The box should be placed in most starting for file, indicate the correlation of MP4 files application
Information.Moov box equally only one, under normal circumstances, " moov " can follow " ftyp " appearance closely, under normal circumstances, in moov
1 mvhd and several trak can be included.Wherein mvhd is header box, is occurred generally as first sub- box of moov
(for other container box, header box, which should be used as first sub- box, to be occurred), trak must include one
Tkhd and mdiz, in addition with many optional box.
In all box, filling information and data are relatively more and important box is stbl box (sample
Table box), which contains sample institute's having times and the information of position, and coding information of sample etc., is MP4
Most complicated box in format container, can contain the next stage box such as stsd, stts and stsz.
Stsb contains data type information and the information of coding, such as：The coding mode of audio and video, the width of video and
The high, sound channel of audio.
Stts stores the duration information of sample (sample), describes the mapping relations of sample sequential, and crossing it can be with
Find the sample. of any time
Stsz contains the size information of sample.
Above box belongs to the index matrix section of container, and in MP4 format containers, video, the data of audio are in mdat
Stored in box.
H.264 the video flowing (file) encoded is made of a series of NAL unit, and one-frame video data is encapsulated in one
A or multiple NAL units.
One optional schematic diagram of the form for the stream file that H.264 use as shown in Fig. 6-2 encodes, including SPPS and
SEI Supplemental Enhancement Informations (SEI, Supplemental Enhancement Inforamtion) are decoded for video；Wherein,
SPPS points are sequence parameter set (SPS, Sequence Parameter Set) and picture parameter set (PPS, Picture
Parameter Set), including the essential information such as video height, width；Further include image sets namely continuous image (GOP,
Group Of Picture), each GOP includes refresh frame (IDIR, Instantaneous Decoding Refresh) immediately
With non_IDR frames, non_IDR frames refer to the non-every IDR frame for being included in P frames etc..
Step 205, transfer backstage carries out piecemeal processing to the media information stream file and promotion message stream file, is formed
Support independent decoded blocked file.
In one embodiment, transfer backstage uses the time of length-specific as piecemeal length, to media information current text
Part and promotion message stream file carry out piecemeal processing and form blocked file, in order to realize that each blocked file is transferred to user side energy
The purpose being enough decoded independently, in each blocked file can also encapsulate description information for indicate how to blocked file into
Row decoding, certainly, since description information can be multiplexed for each blocked file of same stream file, description
Information can also be encapsulated only in first blocked file that piecemeal is handled.
For example, carry out piecemeal processing for stream file (media information stream file as the aforementioned, or promotion message file)
An optional processing schematic diagram as shown in Fig. 6-3, media information stream file is carried out with specific piecemeal length (1 minute)
Piecemeal, in each blocked file, except the stream file piecemeal including media information stream file, further includes for the stream file
Piecemeal carries out independent decoded description information.
Wherein, when stream file is that the coded data compressed based on H.246 algorithm coding is packaged to obtain, piecemeal
Description information in file is SSPS information；For another example when stream file is the coded number that is compressed based on H.264 algorithm coding
During according to being packaged to obtain, the description information in blocked file is transport stream format information (ADTS, Audio Data
Transport Stream) information.
For another example carried out for stream file (media information stream file as the aforementioned, or promotion message file) at piecemeal
Shown in the optional processing schematic diagram Fig. 6-4 of one of reason, media information stream file is carried out with specific piecemeal length (1 minute)
Piecemeal, in first obtained blocked file, except the stream file piecemeal including media information stream file, further include for pair
The stream file piecemeal carries out independent decoded description information, since the description information in first blocked file can be for user side
Player other blocked files in same stream file are decoded, therefore, in other blocked files can only include stream
File block, to reduce the complexity of piecemeal processing.
To carry out piecemeal processing to stream file as piecemeal length using the length-specific time in previous embodiment, in
Turn for platform, here, piecemeal length used in progress piecemeal processing can be changeless, use unified piecemeal to grow
Degree carries out piecemeal to all media information stream files and promotion message stream file, so that when user side asks media information,
Ensure the data continuity of media information returned to user side.
In another embodiment, ability to play requirement of the piecemeal length difference then to user side player also differs,
Piecemeal length can be otherwise varied according to the ability to play with different user side, transfer broadcasting of the backstage based on the user side
Ability determines the piecemeal length being adapted.
For example, the quantized value based on user side player (client) ability, including the video resolution of support, decoding energy
The quantized value of power, the Container Format supported etc., the quantized value of resource (workable caching) situation of client, calculates to user
The length (point fast length) of the blocked file of side transmission, usually, ability to play and the piecemeal length of user side are positive correlation (examples
Such as, linear positive correlation) relation, the ability to play of user side is more strong, and the piecemeal length supported is also bigger.
It is bigger to the piecemeal length of user side transmission when the ability to play of user side is stronger, save network transmission time
Number, reduces because being spaced larger since network transmission bandwidth limits between blocked file, causes the decoding of blocked file to broadcast
Discontinuous problem is put, ensures the result of broadcast in user side smoothness.
Step 206, address structure playlist of the transfer backstage based on the blocked file.
Step 207, transfer backstage returns to the playlist to the user side.
Step 208, the lateral transfer backstage of user sends the request of data of the address based on the blocked file.
In one embodiment, in step 206, transfer is from the background according to the promotion message relative to the media information
Playing sequence, the address of the corresponding piecemeal for arranging the media information stream file and point of the promotion message stream file
The address of block, the playlist is formed based on the address arranged.
For example, it is assumed that after carry out piecemeal for media information stream file, video blocked file 1 and video piecemeal are formed
File 2, after carrying out piecemeal for promotion message stream file, forms advertisement blocked file 1 and advertisement blocked file 2.
So, when needing to play bumper advertisements before user watches video, M3U8 is formed based on blocked file address
One example of playlist is as follows：
#EXTM3U
1 address of advertisement blocked file+advertisement blocked file 1.ts
2 addresses of advertisement blocked file+advertisement blocked file 2.ts
Video blocked file 1+ video blocked files 1.ts
Video blocked file 2+ video blocked files 2.ts
#EXT-X-ENDLIST
It is not shown in above-mentioned M3U8 playlists and the other details in addition to blocked file puts in order, this area skill
Art personnel putting in order based on above-mentioned blocked file can implement complete M3U8 playback volumes listing file easily.
As can be seen that each blocked file in M3U8 playlists provides the full detail of positioning blocked file：Point
The storage address of block file and blocked file title.After user side is getting above-mentioned playlist, it can be played according to M3U8
Each blocked file putting in order to corresponding Address requests blocked file and being decoded in user side and plays in list, so as to fulfill
The advertisement blocked file 1 and advertisement blocked file 2 of bumper advertisements are played first, then play 1 He of video blocked file of video
The effect of video blocked file 2.
It is to be appreciated that other the opposite playing sequences for the video and bumper advertisements watched are needed for user, as long as
The arranged opposite order of corresponding sub-block file is adjusted in M3U8 playlists, for example, when needs are in the playing process of video
During middle broadcasting bumper advertisements, an optional example of corresponding M3U8 playlists is：
#EXTM3U
1 address of advertisement blocked file+advertisement blocked file 1.ts
2 addresses of advertisement blocked file+advertisement blocked file 2.ts
Video blocked file 1+ video blocked files 1.ts
Video blocked file 2+ video blocked files 2.ts
#EXT-X-ENDLIST
In another embodiment, in order to avoid user side content filtering function based on the file name in playlist
The situation that promotion message is filtered is carried out to advertisement, such as content filtering function can be based on the sensitive word in playlist
" advertisement " and block the communication process that user side obtains the corresponding blocked file of advertisement.For this problem, in the played column
Be in table the media information stream file piecemeal and the promotion message piecemeal distribution same names prefix, and with
Numbering is the piecemeal of the media information stream file and the piecemeal distribution name of the promotion message to the playing sequence accordingly
Claim suffix.
For example, for the foregoing M3U8 playlists that bumper advertisements are played before video is played, can be changed to：
#EXTM3U
FileSequence1 addresses+fileSequence1.ts
FileSequence2 addresses+fileSequence2.ts
FileSequence3 addresses+fileSequence3.ts
FileSequence4 addresses+fileSequence4.ts
#EXT-X-ENDLIST
As can be seen that since the piecemeal of media information stream file and the piecemeal of the promotion message distribute same names
Prefix " fileSequence ", for the content filtering function of user side, the title for being based purely on blocked file can not area
Divide video and bumper advertisements, so as to easily pass around the detection of content filtering services, make the blocked file of bumper advertisements suitable
The player that profit is transferred to user side plays out.
In another embodiment, in order to avoid user side content filtering function based on the file in playlist not
Situation about being filtered with storage address to promotion message, is identified with the source of the blocked file of video information not for example, working as
(source address of video can pass through collecting to existing video database during the blocked file of the same promotion message
To), i.e., the communication that bumper advertisements are obtained to user side shields.For this problem, transfer backstage can be in same position
The piecemeal of the media information stream file and the piecemeal of the promotion message stream file are stored (for example, local on transfer backstage
Storage, alternatively, being stored in same content distributing network), it is thus possible to be the media information current text in the playlist
The piecemeal of part, in the playlist be the piecemeal of the media information stream file and the promotion message stream file
Piecemeal distributes identical address prefix, and described address prefix is directed toward the position of storage corresponding sub-block.
For example, the foregoing M3U8 playlists that bumper advertisements are played before video is played, can be changed to：
#EXTM3U
http://fileSequence+fileSequence1.ts
http://fileSequence+fileSequence2.ts
http://fileSequence+fileSequence3.ts
http://fileSequence+fileSequence4.ts
#EXT-X-ENDLIST
As can be seen that due to the piecemeal of the media information stream file and the piecemeal of the promotion message stream file
Identical source address is " http://fileSequence ", this has just prevented the content filtering services shielding user of user side
Side obtains the situation of the blocked file of bumper advertisements.
Step 209, blocked file is transmitted in transfer backstage to the user side.
Step 210, user side player decoding plays blocked file.
In one embodiment, in order to realize in the case of the network transmission bandwidth stabilization of transfer background user side, in
Turn the single cbr (constant bit rate) that backstage can determine to be adapted based on network transmission bandwidth and the positive correlation of code check, for example,
The more big then code check of network transmission bandwidth is higher, so that the credit rating of coded data is higher, based on single cbr (constant bit rate) to matchmaker
Body information and promotion message are compressed coding, and the media information stream file and promotion message stream file obtained to coding divides
Block, therefore, the code check of the formed blocked file of piecemeal processing is also single cbr (constant bit rate).
Fluctuation inevitably occurs for the network transmission bandwidth of transfer backstage and user side, it is necessary to realize that such technology is imitated
Fruit：Network transmission bandwidth higher transmission high quality rank blocked file to be lifted at the result of broadcast of user side, and in net
The blocked file with respect to low quality level is transmitted in the case that network transmission bandwidth is relatively low to ensure that the smooth broadcasting of user side is imitated
Fruit.
Correspondingly, in another embodiment, transfer backstage can be based on the corresponding code check of at least two quality scales, point
It is other that the media information and the promotion message are carried out to encode the coded data for forming phase code rate, obtained corresponding to encapsulation
Coded data forms the media information stream file of phase code rate and the promotion message stream file, and to promotion message stream text
Part and media information stream file carry out piecemeal processing, form the blocked file of different quality rank.
The quality scale that transfer backstage determines to match based on the network transmission bandwidth between the user side, judges institute
State quality scale whether with piecemeal processing used in transport stream quality scale it is inconsistent when, switching use the matched matter
The other transport stream of magnitude carries out piecemeal processing and forms the independent decoded blocked file of support.
One example is as shown in Fig. 6-5 to Fig. 6-7, referring first to Fig. 6-5, in hypertext transfer protocol (HTTP, Hyper
Text Transfer Protocol) layer, transfer backstage establishes the session for being used for transmission blocked file, and session with user side
Control (such as session timeout handle), the adaptive of the quality scale of the blocked file transmitted to user side is also realized on transfer backstage
It should control.
Referring to Fig. 6-6, blocked file is transmitted in transfer backstage with user side using the direction of HTTP request-http response, with
Exemplified by blocked file 1 in user side request playlist, the lateral transfer background request of user is (here, suppose that in playlist
The storage address of blocked file is directed toward transfer backstage) with acquisition request blocked file 1, transfer backstage in a manner of http response to
User side returns to the data of blocked file 1, and since blocked file 1 carries description information, user side is receiving piecemeal text
I.e. decodable code plays after part 1.
In transfer background transfer blocked file, can be determined according to the network transmission bandwidth situation of user side in user side
Ask whether to switch during next blocked file the quality scale of blocked file, referring to Fig. 6-7, transfer backstage passes through three aspects
Information：The resource situation of current network, the situation and media of the client of active user side are from the background for the media of adaptation
Information, judge transmission piecemeal quality scale whether with current bandwidth Optimum Matching, and combine client ability (support
Video resolution, decoding capability, the Container Format etc. supported) and resource (workable caching) situation and transfer from the background for
The media information of adaptation determines whether need quality of handoff rank during the next stream file piecemeal of transmission/reception.Wherein, using current
The time of the media file piecemeal of transmission/reception calculates current network bandwidth.
The functional structure that device is promoted to aforementioned information illustrates, referring to one of the information popularization device 20 shown in Fig. 7
A optional illustrative view of functional configuration, including：Encapsulation unit 21, blocking unit 22, list cell 23 and transmission unit 24, below
Each unit is illustrated.
Encapsulation unit 21, for being encoded respectively to media information and promotion message, the coding obtained corresponding to encapsulation
Data form media information stream file and promotion message stream file.
In one embodiment, the encapsulation unit 21, is additionally operable to the number according to the media information, the promotion message
Corresponded to according to form and be compressed coding, wherein the data format includes at least one video format and audio format.
For example, being compressed coding to the media information of video format using video compression algorithm, calculated using audio compression
Method is compressed coding to the media information of audio format；Similarly, believed using popularization of the video compression algorithm to video format
Breath is compressed coding, and coding is compressed to the promotion message of audio format using audio compression algorithm.
In one embodiment, the encapsulation unit 21, is additionally operable to fill the media in the track of the first format container
The coded data of information obtains the media information stream file, and, believe in described promote of track filling of the second format container
The coded data of breath obtains the promotion message stream file.
For example, the encapsulation for coded data is adopted in such a way, the matchmaker is filled in the track of the first format container
The coded data of body information obtains the media information stream file, and the promotion message is filled in the track of the second format container
Coded data obtains the promotion message stream file.Wherein, the first format container can be identical lattice with the second format container
Formula container, such as MP4 format containers；It is of course also possible to be the container of different-format, such as the first format container is MP4 forms
Container, the second format container are MKV format containers, or are FLV format containers.
Blocking unit 22, branch is formed for carrying out piecemeal processing to the media information stream file and promotion message stream file
Hold independent decoded blocked file.
For another example carried out for stream file (media information stream file as the aforementioned, or promotion message file) at piecemeal
Shown in the optional processing schematic diagram Fig. 6-4 of one of reason, media information stream file is carried out with specific piecemeal length (1 minute)
Piecemeal, in first obtained blocked file, except the stream file piecemeal including media information stream file, further include for pair
The stream file piecemeal carries out independent decoded description information, since the description information in first blocked file can be for user side
Player other blocked files in same stream file are decoded, therefore, in other blocked files can only include stream
File block, to reduce the complexity of piecemeal processing.
It is foregoing that piecemeal processing is carried out to stream file using the use length-specific time as piecemeal length, come for transfer platform
Say, here, piecemeal length used in progress piecemeal processing can be changeless, using unified piecemeal length to all
Media information stream file and promotion message stream file carry out piecemeal so that when user side asks media information, ensure to
The data continuity for the media information that family side returns.
In one embodiment, the blocking unit 22, is additionally operable to the ability to play based on the user side and determines mutually to fit
The piecemeal length matched somebody with somebody, the media information stream file and promotion message stream file are carried out at piecemeal with identified piecemeal length
Reason forms blocked file, at least one blocked file encapsulation decoded information.
Piecemeal length difference then also differs the requirement of the ability to play of user side player, piecemeal length can according to
The ability to play of different user side and it is otherwise varied, ability to play of the blocking unit 22 based on the user side determines what is be adapted
Piecemeal length.
For example, the quantized value based on user side player (client) ability, including the video resolution of support, decoding energy
The quantized value of power, the Container Format supported etc., the quantized value of resource (workable caching) situation of client, calculates to user
The length (point fast length) of the blocked file of side transmission, usually, ability to play and the piecemeal length of user side are positive correlation (examples
Such as, linear positive correlation) relation, the ability to play of user side is more strong, and the piecemeal length supported is also bigger.
It is bigger to the piecemeal length of user side transmission when the ability to play of user side is stronger, save network transmission time
Number, reduces because being spaced larger since network transmission bandwidth limits between blocked file, causes the decoding of blocked file to broadcast
Discontinuous problem is put, ensures the result of broadcast in user side smoothness.
List cell 23, playlist is built for the address based on the blocked file, and institute is returned to the user side
State playlist.
In one embodiment, the list cell 23, is additionally operable to relative to the media be believed according to the promotion message
The playing sequence of breath, the address of the corresponding piecemeal for arranging the media information stream file and the promotion message stream file
The address of piecemeal, the playlist is formed based on the address arranged.
For example, it is assumed that after carry out piecemeal for media information stream file, video blocked file 1 and video piecemeal are formed
File 2, after carrying out piecemeal for promotion message stream file, forms advertisement blocked file 1 and advertisement blocked file 2.
So, when needing to play bumper advertisements before user watches video, M3U8 is formed based on blocked file address
One example of playlist is as follows：
#EXTM3U
1 address of advertisement blocked file+advertisement blocked file 1.ts
2 addresses of advertisement blocked file+advertisement blocked file 2.ts
Video blocked file 1+ video blocked files 1.ts
Video blocked file 2+ video blocked files 2.ts
#EXT-X-ENDLIST
It is not shown in above-mentioned M3U8 playlists and the other details in addition to blocked file puts in order, this area skill
Art personnel putting in order based on above-mentioned blocked file can implement complete M3U8 playback volumes listing file easily.
As can be seen that each blocked file in M3U8 playlists provides the full detail of positioning blocked file：Point
The storage address of block file and blocked file title.After user side is getting above-mentioned playlist, it can be played according to M3U8
Each blocked file putting in order to corresponding Address requests blocked file and being decoded in user side and plays in list, so as to fulfill
The advertisement blocked file 1 and advertisement blocked file 2 of bumper advertisements are played first, then play 1 He of video blocked file of video
The effect of video blocked file 2.
It is to be appreciated that other the opposite playing sequences for the video and bumper advertisements watched are needed for user, as long as
The arranged opposite order of corresponding sub-block file is adjusted in M3U8 playlists,
In one embodiment, the list cell 23, is additionally operable in the playlist be the media information current
The piecemeal of the piecemeal of file and the promotion message stream file distributes same names prefix, and is according to the playing sequence
The piecemeal distributes corresponding sequence number as title suffix.
In another embodiment, in order to avoid user side content filtering function based on the file name in playlist
The situation that promotion message is filtered is carried out to advertisement, such as content filtering function can be based on the sensitive word in playlist
" advertisement " and block the communication process that user side obtains the corresponding blocked file of advertisement.For this problem, the list cell
23, it is additionally operable in the playlist be the piecemeal of the media information stream file and the promotion message stream file
Piecemeal distributes identical address prefix, and described address prefix is directed toward the position of storage corresponding sub-block.As can be seen that due to media information
The piecemeal of the piecemeal of stream file and the promotion message distributes same names, for the content filtering function of user side,
The title for being based purely on blocked file cannot be distinguished by video and bumper advertisements, so as to easily pass around content filtering services
Detection, makes the blocked file of bumper advertisements smoothly be transferred to the player of user side and plays out.
In one embodiment, the list cell 23, is additionally operable to obtain the mark for the media information that user side request plays
The mark for the promotion message that knowledge and user side request play, according to encoding acquired mark acquisition needs
Media information and the promotion message.
In one embodiment, in order to realize in the case of the network transmission bandwidth stabilization of transfer background user side, institute
The single cbr (constant bit rate) that encapsulation unit 21 can determine to be adapted based on network transmission bandwidth and the positive correlation of code check is stated,
For example, the more big then code check of network transmission bandwidth is higher, so that the credit rating of coded data is higher, based on single cbr (constant bit rate)
Coding is compressed to media information and promotion message, to the obtained media information stream file of coding and promotion message stream file into
Row piecemeal, therefore, the code check of the formed blocked file of piecemeal processing is also single cbr (constant bit rate).
