The charging method of the streaming media service that the embodiment of the invention provides is on the basis of adaptive stream media technology, to realize.The adaptive stream media technology comprises adaptive H ttp Streaming Media (AHS) technology.The basic thought of AHS technology is: at the media data code stream of server generation various code rate, for example corresponding m mass is designated as Q0, Q1, Q2 respectively ..., Qm-1; Every kind of code stream is cut into n fragment, respectively time corresponding length be T0, T1, T2 ..., Tn-1.Adaptive code stream is downloaded and can be realized through two kinds of patterns: server push and final drive, and wherein under the pattern of server push, server is the code stream that respective quality is selected at the terminal according to the characteristics and the network condition at terminal; Under the pattern of final drive, the terminal is according to the disposal ability of self and the code stream fragment of network condition selection download respective quality.This adaptive process is along with the time changes.Server can produce medium and present description (Media Presentation Description, MPD) file sends to the terminal, the information such as code check, Http address of each code stream fragment of indication in this document.Corresponding code stream selection and switching can be done according to this MPD file and network environment and terminal processes in the terminal.If this media content receives copyright protection, user side also need provide the user right data file when playing this media content so, and this user right data file is used at this media content of user side deciphering.Usually, the user right data file comprises following parameter: content key, term of validity time started, term of validity concluding time, watch authority (browse, download, forwarding etc.) etc.In embodiments of the present invention, can quality price rate information be joined above-mentioned medium appears in description MPD file or the user right data file.
Referring to Fig. 1, the charging method of the streaming media service that the embodiment of the invention provides comprises:
Step S101: the quality price rate of media data code stream of obtaining the different quality of same streaming medium content; The quality price rate of the code stream of each quality is to confirm with reference to the relation of the real price of this data Quality code stream and standard price, and said standard price is the real price of data code flow of an extra fine quality of streaming medium content;
Wherein, the quality price rate of the code stream of each quality equals the real price of this data Quality code stream and the ratio between the said standard price.
Step S102:, confirm to play the paying rate of this streaming medium content according to above-mentioned quality price rate according to the quality that in the playing stream media contents, is directed against the code stream fragment of being downloaded in each time slice;
Step S103:, obtain the actual cost of the above-mentioned streaming medium content of terminal plays according to paying rate that obtains among the step S102 and above-mentioned standard price.
Step S104:, the user is chargeed according to the actual cost that obtains among the step S103.
Above-mentioned steps S101 can be a message accounting to the executive agent among the step S104, and this message accounting can be arranged in each terminal, and this moment, this message accounting only was responsible for the Streaming Media billing function at its terminal, place; In addition, message accounting also can be arranged in the central control equipment, and the message accounting in the central control equipment is responsible for the streaming media service billing function at all terminals in the network range that this central control equipment administers.
This shows; Method provided by the invention is added up the actual cost of playing stream media content to the quality of the code stream fragment of being downloaded in each time slice in the playing stream media contents according to the terminal; This just makes final actual cost consider in watching process because the expense that the switching of code stream quality causes changes, makes that finally to obtain actual cost fairer and more reasonable.
Below specify concrete realization of the present invention with several concrete examples.
Embodiment one
In the present embodiment with the AHS Streaming Media, and the download of adaptive stream media data code flow to adopt the mode of final drive be that example describes, this method comprises the steps:
Step S201: server produces AHS stream medium data code stream, and the MPD file.The concrete realization of this step is existing about the description of AHS technology in the present 3GPP standard, only simple declaration here.
Suppose that server produces the media data code stream of m mass, m is the natural number more than or equal to 1, the quality of these code streams can be designated as respectively Q0, Q1, Q2 ..., Qm-1.Wherein, Q0＞Q1＞Q2＞...＞Qm-1.The media data code stream of every mass is divided into n fragment, and n is the natural number more than or equal to 1, and the time span of these fragments is respectively T0, T1, and T2 ..., Tn-1.The code flow structure that produces can be referring to Fig. 3.
The MPD file that produces can comprise the information such as quality, time span and address of media data code stream.In the MPD file as shown in Figure 4, the code stream of a certain quality of " Representation " expression, the corresponding quality of " Quality " expression code stream, the time span of " segmentLength " indication code flow section.In reality, the quality of data code flow can be weighed through the various parameters of code stream quality that can reflect, for example the code check of the sample rate of the resolution of every frame picture, code stream and code stream (PSNR) in the code stream.Need to prove, only launch to show the information of each fragment in the MPD file of m-1 code stream among Fig. 4, in fact in the MPD file, also have the information of each fragment of other code streams certainly.
Step S202: server defines the real price of stream medium data code stream of a certain extra fine quality of same streaming medium content, as standard price.In reality, can define the price of the media data code stream of first water in the media data code stream in the multiple different quality that same streaming medium content is generated, the price of the multi-medium data code stream of minimum quality in the middle of can certainly defining.
Step S203: server is based on the quality height of adaptive stream media data code flow; Media data code stream definition quality price rate to the different quality of same streaming medium content; This quality price rate has reflected the ratio between the standard price that defines among price and the step S202 of this data Quality code stream; And quality is high more, and this ratio is big more; Quality is low more, and this ratio is more little.
For example, be that the media data code stream of Q0 is a standard price if the price of the highest media data code stream of definition quality as standard price, has promptly defined quality, might as well be designated as C.The quality price rate of the media data of each quality will satisfy so:
1＝R
0＞＝R
1＞＝...＞＝R
m-1＞＝0
In reality, can set quality threshold Q
T1, just charge accordingly when being not less than this threshold value for the data code flow quality of only watching, for quality price rate following constraints is just arranged so:
R
i=0, if Qi＜Q
T1
Wherein i ∈ 0,1,2 ..., m-1}.
Certainly, also can set quality threshold Q
T2, adopt identical rate to calculate when being higher than this threshold value for the data code flow quality of watching, for quality price rate following constraints is just arranged so:
R
i=1, if Qi＞Q
T2
Wherein i ∈ 0,1,2 ..., m-1}
Step S204: server passes to the terminal with the quality price rate of above-mentioned definition, and in the present embodiment, server can join quality price rate in the MPD file of generation and send to the terminal.
Thus, server joins the new file that is generated in the MPD file with quality price rate and can be called the PMPD file.
Fig. 5 shows the content that adds the PMPD file that quality price rate forms on the basis of the MPD file in Fig. 4, wherein QualityPriceRate
iRepresent the quality price rate that i code stream is corresponding, i ∈ 0,1,2 ..., m-1}.
Need to prove that quality price rate is not limited only to above-mentioned mode through the PMPD file transfers; Can also be placed in the permissions data file of user terminal and be passed to the terminal, usually, the user right data file comprises following parameter: content key, term of validity time started, term of validity concluding time, watch authority (browse, download, forwarding etc.) etc.; Quality price rate also can be passed to the terminal separately with other mode.
Step S205: the information in the terminal parses PMPD file, the information such as quality, time span and address of the relevant code stream that obtains to have in the MPD file itself can also obtain to add the quality price rate information of wherein each code stream.
In reality, can resolve the numerical value of above-mentioned each parameter and parameter through parameter identification.
Certainly; If quality price rate information is not to join in the MPD file; The quality price rate information that obtains need be resolved through the file of Transfer Quality price rate in the terminal so; If quality price rate information passes to the terminal separately through other forms, the terminal only need be resolved this information of transmitting separately and can be obtained quality price rate information so.
Anyway, give the terminal as long as quality price rate does not join the MPD file transfers, what server sent to the terminal so is original MPD file, terminal parses also be this MPD file.
Step S206: the terminal is to the adaptively selected code stream of each time slice, and the process of this adaptive code stream comprises: the disposal ability of media data and current network condition (for example bandwidth) are confirmed the quality of the current code stream that should ask according to self.
Terminal self can obtain through the hardware setting information of reading terminals the disposal ability of media data; And current network condition can be obtained through reading network setup information.During the quality of the code stream that two factors are confirmed to ask on comprehensive, can with lower in two factors be the quality of the definite code stream that should ask of standard.
The quality of the current code stream of confirming that should ask should belong to the defined code stream quality of server; The code stream quality of for example carrying through PMPD file or alternative document; But in reality; Code stream quality in that the disposal ability of considering media data and current network bandwidth institute directly confirm often and between the predefined code stream quality of server can not be mated fully, so this just exists on earth the quality of which code stream in the PMPD file quality as the definite current code stream that should ask.In the present embodiment; Adopt method relatively to confirm; Particularly; The code stream quality of directly confirming when the disposal ability through considering media data and current network bandwidth institute is q, and then relatively seeking in the PMPD file in the m kind code stream quality near this q and that code stream quality of being not more than q is exactly the quality of the final definite current code stream that should ask.Parameter with the code stream quality comprises that code stream is an example; If disposal ability and current network bandwidth through media data are confirmed the medium code stream that the current maximal rate that can handle is B; Through the code check parameter in the quality that compares the numerous code streams in the PMPD file, the discovery quality is Q so
BThe code check of code stream be less than the maximum among the B, confirm that therefore the current quality of should asking is Q
BThe code stream fragment.
This shows, in embodiments of the present invention, the quality of the code stream that the terminal need be selected next to receive according to current actual conditions adaptively.Supposing to receive whole streaming medium content in final terminal, to accomplish the selection course of the code stream fragment that is experienced as shown in Figure 6, wherein S
I, jThe expression quality is Q
iJ+1 code stream fragment of code stream, the solid line that between the code stream of each quality, streaks is illustrated in the selection track of the selected code stream fragment of each time slice, the media data code stream that is finally finished receiving fully by the terminal is by S
0,0, S
0,1, S
1,2S
M-1, n-2, S
1, n-1N code stream fragment composition.
Step S207: the terminal can be downloaded content according to the address of this code stream fragment that parses in the PMPD file, and play the content of this fragment to after the adaptively selected code stream fragment of each time slice.
Certainly, if server is not to add quality price rate through the MPD file, then among the step S207, what resolved at the terminal is exactly the MPD original document.
Step S208: the paying rate p of this streaming medium content is added up according to the quality of selected code stream fragment in each time slice of playing at same streaming medium content in the terminal.
Can adopt the mode of three kinds of concrete statistics paying rates in the present embodiment, be respectively:
Mode 1: the media data code stream of statistics different code streams quality watch length, its detailed process is:
In terminal pins during to each time slice option code flow section; The quality of record code flow section place code stream and the time span of code stream fragment; At last the quality price rate of all code stream fragments of the selection in the streaming medium content playing process is carried out weighted sum according to the weight factor of this quality price rate, obtain paying rate p.When calculating weighted sum, the weight factor of each code stream fragment account for for the time span of this code stream fragment whole streaming medium content code stream total time length ratio.
For example, if T
iBe the time span of i+1 selecteed code stream fragment, wherein i ∈ 0,1,2 ..., n-1}.And the total time length of the code stream of whole streaming medium content is T=T
0+ T
1+ ...+T
N-1
The process that the paying rate is calculated in then above-mentioned weighted sum can be expressed as:
Wherein, R '
i∈ { R
0, R
1, R
2..., R
N-1It is the quality price rate of i+1 selecteed media code flow section place code stream.For example, if code stream fragment S
J, iSelected, then in the computing formula of above-mentioned weighted sum, R '
i=R
j
Mode 2: the switching frequency of the media code flow section of statistics different code streams quality, its detailed process is following:
At first; When the quality of two adjacent selected code stream fragments of time slice not simultaneously, judge that code stream takes place to be switched, for example in the code stream fragment selection course shown in Fig. 6; When selecting the 3rd time slice, because that the 2nd time slice selection is code stream fragment S
0,1, be code stream fragment S and next the 3rd time slice select
1,2The quality of the code stream at these two adjacent code stream fragment places is different, therefore code stream takes place switch.
Then, add up the number of times that whole streaming medium content is play the code stream switching that is taken place, be designated as L.
The number of times that the statistics code stream switches can have a variety of concrete implementations, for example can be between every adjacent two code stream fragments of choosing the switching mark position being set, and when code stream taking place switch, be 1 with the switching mark position of correspondence, otherwise be changed to 0.Calculate at last all flag bits with, just obtained the number of times that code stream switches.A register can certainly be set, initial zero setting, whenever taking place to add up 1 when code stream switches, after all code stream fragments of streaming medium content had been selected, the result in this register was exactly the number of times that code stream switches.
Calculate paying rate p then, the paying rate is that the actual number of times that the code stream switching does not take place accounts for the above-mentioned preset peaked ratio of code stream switching times in the code stream switching times maximum of presetting in the streaming medium content playing process.
Above-mentioned preset code stream switching times maximum equals at most the code stream switching times can take place in the streaming medium content playing process.
It still is example with Fig. 6; When the number of the code stream fragment of streaming medium content is n, be not difficult so at most to draw that the number of times that code stream switches can take place at most is n-1, promptly; The maximum of preset code stream switching times is n-1, and the then actual number of times that the code stream switching does not take place is n-1-L.Therefore calculating the paying rate can realize through following formula:
p＝(n-1-L)/(n-1)
Mode 3: add up the switching frequency of the media code flow section of different code check quality, consider the code stream quality gap of switching simultaneously, detailed process is following:
At first add up the number of times that whole streaming medium content is play the code stream switching that is taken place with reference to the implementation in the aforesaid way 2.
Calculate the distance B that each code stream switches simultaneously
k, k ∈ 0,1,2 ..., L-1}, 1≤D
k＜m.The distance that code stream switches can be defined as the absolute value of the difference between the quality sequence number of quality sequence number and back one code stream fragment of the last code stream fragment that code stream switching place takes place, and the quality sequence number of the code stream fragment here is to confirm according to the rank of quality in the quality of all code streams of same streaming medium content of this code stream fragment place code stream.The distance that actual code stream switches in the distance B k statistics playing stream media contents of switching according to each code stream with.
For example, if the code stream quality of last code stream fragment is Q
i, the code stream quality of back one code stream fragment is Q
j, the distance of then between these two code stream fragments, switching does | i-j|, wherein | | be the operation that takes absolute value.
Then calculate paying rate p, the paying rate be the switching code stream that can produce in the above-mentioned streaming medium content playing process distance and maximum subtract distance that actual code stream switches and gained difference and the above-mentioned switching code stream that can produce distance and peaked merchant.
The media data code stream that has m kind different quality when same streaming medium content; When each media data code stream is divided into n segment encode flow section; The switching code stream that can produce in then above-mentioned this streaming medium content of broadcast is apart from the peaked situation of sum; Code stream all takes place between adjacent exactly two time slices switch (promptly actual code stream switching times is n-1); And code stream switches all the time between the highest code stream of the minimum code stream of quality and quality and carries out (each switching distance is m-1 all), so the switching code stream that can produce just equals (n-1) (m-1) apart from the maximum of sum.
Particularly, paying rate p can calculate through following formula:
Or
Step S209: according to the paying rate p that obtains among the step S208 and the real price of media data code stream of the extra fine quality of this streaming medium content of definition before, promptly standard price C calculates the actual cost that the user watches streaming medium content.
For the mode of paying in the back, system can watch the back that finishes to deduct the actual cost that the user watches streaming medium content the user;
For the mode of pre-payment, system begins and can collect the charges earlier according to standard price, returns the overcharge and demand payment of the shortage according to actual cost afterwards.If for example system is according to the price definition standard price of the multi-medium data code stream of first water; What then the user paid when pre-payment will be the highest expense that possibly pay; And when the user watch finish after; The actual cost that system-computed goes out often is lower than this mark price, so system also can compensate the difference of the two to the user, returns.
Need to prove; Above-mentioned steps S208 and step S209 can be carried out by the terminal; Also can carry out by central control equipment; For example in home network, the central control equipment of this execution in step S208 and step S209 can be the family gateway equipment in the home network, control centre or STB, can realize statistics and charging to the viewing quality of a plurality of media terminations in the family through central control equipment like this.
In addition; Owing to be to adopt final drive in the foregoing description; Be the quality of coming option code flow section by the mode of final drive among the step S206, and in the embodiment that other substitutes, also can adopt the mode of server driven to come the quality of option code flow section; To be replaced by terminal when playing stream media content among the step S206 this moment; To each time slice, the quality that server is selected the code stream fragment of terminal downloads according to the disposal ability and the current network conditions at terminal, and indicating terminal is downloaded the code stream fragment of this quality.
The also corresponding message accounting that a kind of streaming media service is provided of the embodiment of the invention, as shown in Figure 7, this device comprises: quality price rate acquiring unit 701, paying rate statistic unit 702 and Charging Detail Record unit 703.
Wherein, Quality price rate acquiring unit 701 is used to obtain the quality price rate that server is set that the media data flow of different quality of same streaming medium content; The quality price rate of the code stream of each quality is to confirm with reference to the relation of the real price of this data Quality code stream and standard price, and said standard price is the real price of data code flow of an extra fine quality of said streaming medium content.
The quality price rate that the quality price rate of the code stream of above-mentioned each quality can equal this data Quality code stream equals the real price of this data Quality code stream and the ratio between the standard price.
The detailed process that quality price rate is set and the definition of standard price are identical with related content among the said method embodiment, repeat no more here,
