It is how to carry out business to broadcast parameter and adjust automatically that method embodiment 2 of the present invention is presented in the DVB system headend equipment by a more specific example, and idiographic flow can describe by accompanying drawing 3

201, in the process of DVB system operation, the terminal equipment of headend equipment in system sends the request of the business information state that obtains each terminal equipment;

Implementing in 201, the mode that headend equipment can send solicited message sends the request of the business information state that obtains each terminal equipment to terminal equipment, the status indicator of respective field that also can be by the control messages that in the process of issuing service information, sends, for example: for a control information, the definition highest order is the request mark position that obtains the business information state of each terminal equipment, when this bit is 1, the expression headend equipment need obtain the business state information of this terminal equipment, when this bit was 0, the expression headend equipment did not need to obtain the business state information of described terminal equipment; Can also adopt the mode of agreement to realize, be specifically as follows: headend equipment and each terminal equipment agreement, by the transmission request of headend equipment timing or not timing, in the described timed sending request, the described time interval can be 5 seconds, 10 seconds.

202, terminal equipment gets access to after the request of the business information state that obtains this terminal equipment that headend equipment sends, and starts the detection to self relevant business information;

Implementing 202 o'clock, the business information that terminal equipment is relevant comprises: the professional operating position information of terminal, the business datum of terminal are broadcast the current state information of situation information and terminal equipment.Wherein, the professional operating position information of terminal comprises: terminal equipment obtains the handover information of user to channel by the mode of statistics, which programme information watch duration information and user to some programs watch (for example: evening 19:00-19:30 in section sometime, the user watches the Chinese Central Television's the 1st channel, still watches the 10th channel); The business datum of terminal is broadcast situation information and comprised: the business of different programs is play code check etc.; The current state information of terminal equipment comprises: the operating position of the CPU of terminal equipment and when playing current business, the operating position of internal memory.

Be appreciated that terminal equipment can also detect following information except the business information relevant with terminal of above-mentioned introduction:

(1) user's use habit information, be the user generally be when watch TV programme, user's the switching on and shutting down time, user's the classification information of watching program (for example: current political news, sports cast, TV play or the like), these information can obtain according at ordinary times operating position statistics by terminal equipment;

(2) configuration information of user's terminal equipment, i.e. the configuration of subscriber terminal equipment comprises its every functional parameter, for example: the maximum receiving velocity of this terminal, the resolution of image and other relevant informations.

Be appreciated that, also can not adopt this headend equipment to upload and self the mode of business information by terminal equipment to the request of issuing of each terminal equipment, but by each terminal equipment regularly (for example: can set 5 seconds) forward end equipment mode of uploading the business information relevant with self realize the business information that terminal equipment forward end equipment is uploaded and self is correlated with.

203, terminal equipment is uploaded to headend equipment with the described detected business information relevant with self by feedback channel;

Implementing in 203, the described detected business information relevant with self is uploaded to headend equipment by feedback channel, and feedback channel wherein comprises a kind of of following situation: with network-feedback channel after the identical channel of broadcasting, the bidirectional rebuilding and the Internet by network interface.

(1) adopts the channel identical: promptly for broadcast system, generally be unilateral network, in existing broadcast channel, tell a part of bandwidth and be used for transmitting this business information relevant with terminal equipment with broadcasting;

(2) network-feedback channel after the bidirectional rebuilding: promptly existing one-way broadcast systems is carried out the transformation of duplex channel, make it to increase up (promptly from the terminal equipment to the headend equipment) feedback path, by this business information relevant of this up feedback path transmission that increases with terminal equipment;

(3) Internet by network interface: for terminal equipment with Ethernet interface, can adopt by network interface login Internet and finish the headend equipment of this business information relevant with terminal equipment being passed to local side, concrete implementation can be passed through the E1 circuit, or the IP circuit transmits.

204, headend equipment obtains the business information relevant with terminal that terminal equipment is uploaded by feedback channel, and the business information relevant with terminal described that upload in the current DVB system carried out statistical analysis;

Implementing in 204, described in the step of front is a terminal equipment forward end equipment feedback business information relevant with terminal, in fact, in the DVB system, moving hundreds and thousands of terminal equipments, headend equipment obtains the business information relevant with terminal equipment of these terminal equipments by feedback path, it is added up, wherein, the information of concrete statistics comprises: it is professional that the DVBDVB system comprises how many how many terminals and headend equipment terminal equipments in the DVB system issues, specifically be which business, and the broadcast weights that adopt for different business.

If professional broadcasting system need broadcast n kind business information, the speed of broadcasting of its expectation is S=(S ₁, S ₂..., S _n), the quantity of the terminal equipment that current network is being moved is m.Then the detection by terminal equipment feeds back to the feedback information of the headend equipment of local side and is:

$F(S,\mathrm{TERMINAL})=\left\{\begin{array}{cccc}{F}_{11}& F_{12}& \·\·\·& F_{1n}\\ F_{21}& F_{22}& \·\·\·& F_{2n}\\ \·\·\·& \·\·\·& \·\·\·& \·\·\·\\ F_{m1}& F_{m2}& \·\·\·& F_{\mathrm{mn}}\end{array}\right\}$

Wherein, F _IjThe transmission rate of the business that expression terminal equipment i reduces at the j item business need front end equipment of broadcasting, and in whole matrix, each row represent professional transmission rate of the requirement minimizing of a business that terminal equipment customized.

205, headend equipment is after carrying out statistical analysis to the business information relevant with terminal described that upload in the current DVB system, according to the current adjustment strategy of having formulated, current business play adjust.

Implementing in 205, after the business information relevant with terminal equipment described that upload in the current system carried out statistical analysis, according to the current adjustment strategy of having formulated, adjusting the weights of the broadcast of each business information at different terminal equipments, specifically is the professional priority of playing at the weights of the broadcast of each business information.

If working as the quantity of terminal equipment is m, the weight matrix of business was when number of services was n:

W＝{W ₁，W ₂，...W _m}

W wherein _iExpression is satisfied constraints for the weighting function of i item service traffics demand in whole system of the terminal equipment in the DVB system $\underset{i=1}{\overset{i=m}{\mathrm{\Σ}}}{W}_i=1.$

When broadcast is adjusted to current business, specifically can adopt following strategy to adjust:

(1) according to the important level of the business of setting current business is broadcast parameter adjustment

For example: suppose that in the DVB system think identically for the important level of all business of all users, like this according to such strategy, its weight matrix W is:

$\stackrel{\‾}{W}={\left\{\begin{array}{cccc}\frac{1}{m}& \frac{1}{m}& \·\·\·& \frac{1}{m}\end{array}\right\}}_{1\×m}$

Wherein, the quantity number of services of terminal equipment is m.

Being appreciated that above-mentioned example is a kind of simple processing mode, thinking that promptly all business of all users all have identical priority, still, in fact is not like this.The headend equipment of local side can count, in the different periods, the user of zones of different meets normal distribution to the selection of business, number promptly good for some sights, that be subjected to the program of user's welcome has accumulated a large amount of users, and for some professional strong excessively or programs that appreciative value is relatively poor, it is less that the user accepts this professional number.

Therefore, headend equipment is after the business information relevant with terminal equipment that each terminal equipment in the DVB system is uploaded by feedback path carried out statistical analysis, the audience ratings that just can determine which program is than higher, which is lower, and, also can know degree popular with users by these data for the program of some classifications.For example: for 20:00-22:00 at night, the audience ratings of TV play channel is higher, if it is that u is capable that each user's of this TV play channel correspondence weights are adjusted matrix at weights, like this can be by adjusting in the matrix at weights, higher weights are set, preferentially guarantee the transmission rate and the quality of the business of this channel.

Again for example: operator can the business service that provide to the user be provided different grades, select more service for the user, and higher service fee has been paid in service for this reason, like this, for such user, can preferentially guarantee the service quality of every business of this type of user, show that weights adjust in the matrix, higher to the ratio that every weights that should the user all are provided with.

(2) according to the Minimum requirements that satisfies the terminal equipment in the current DVB system current business is broadcast parameter adjustment

Promptly when determining broadcast strategy, need sometimes to guarantee that a certain class program need satisfy the Minimum requirements of terminal equipment, for example: for some public welfare and business information that have warning, the broadcast purpose of this business information is exactly to guarantee that all users can both normally receive this program, therefore, corresponding weights are adjusted in the matrix and should be heightened at the weights of this business, and then guarantee that all terminal equipments can play normally.

For example: establish m=3, n=3 comprise 3 terminal equipments in the promptly current DVB system, and this DVB system establishes for terminal equipment provides 3 business service

$F=\left\{\begin{array}{ccc}3\mathrm{kbps}& 0& 0\\ 1\mathrm{kbps}& 1\mathrm{kbps}& 0\\ 1\mathrm{kbps}& 5\mathrm{kbps}& 5\mathrm{kbps}\end{array}\right\}$

Wherein, each row is represented each professional data traffic volume of a corresponding terminal equipment, and from this top matrix, we can find, for three business, directly the row of representing each business are added up, and obtains maximum value, like this $F\′=\left\{\begin{array}{c}3\\ 5\\ 5\end{array}\right\},$ Corresponding weight matrix $W=\frac{{F\′}^T}{13}=\left\{\begin{array}{ccc}\frac{3}{13}& \frac{5}{13}& \frac{5}{13}\end{array}\right\},$ Noticing that each element carries out normalization divided by 13 in the calculation process, is in order to satisfy the constraints of W matrix.

(3) according to the customer complaint ratio of setting, current business is broadcast parameter adjustment

For operator, because resource is limited, and the user is ever-increasing, sometimes can not satisfy proprietary all demands, so just should meet consumers' demand and reduce on user's the complaint and compromise, by according to a certain proportion of customer complaint, adjust weights and adjust matrix.For example: a certain program, the internal memory that takies is higher and code check is bigger, suitable terminal equipment configuration is preferably under the situation, like this, the business information relevant that gets access to from feedback channel by headend equipment with each terminal equipment, obtain the configuration information of terminal equipment in this system, and then after described business is carried out the analysis of resource occupation, obtain weights and adjust matrix.

For example:

$W_{\mathrm{sat}}=\left\{\begin{array}{c}\mathrm{Sat}(F_{i1},p_1\%)\\ \mathrm{Sat}(F_{i2},p_2\%)\\ \·\·\·\\ \mathrm{Sat}(F_{\mathrm{in}},p_n\%)\end{array}\right\},$ Sat (F _In, p _n%) for satisfying p among all users _nThe needed weight of % traffic demand, pairing is that operator is at the professional patient maximum customer complaint ratio of n kind.For example, when $F=\left\{\begin{array}{ccc}3\mathrm{kbps}& 0& 0\\ 1\mathrm{kbps}& 1\mathrm{kbps}& 0\\ 1\mathrm{kbps}& 5\mathrm{kbps}& 5\mathrm{kbps}\end{array}\right\}$ The time, operator increases along with complaining number of users to increase each professional degree of concern, this moment, total complaint amount was 6, wherein, complaint amount to first business is 3, complaint amount to second business is 2, be 1 to the complaint amount of the 3rd business, so each business proportionally is assigned as by degree of concern $F\′=\left\{\begin{array}{c}\frac{3}{6}\\ \frac{2}{6}\\ \frac{1}{6}\end{array}\right\},$ Corresponding weight matrix $W={F\′}^T=\left\{\begin{array}{ccc}\frac{3}{6}& \frac{2}{6}& \frac{1}{6}\end{array}\right\}.$

Actual weight matrix can be adjusted according to the importance of business again, can improve its weight for important business, can reduce weight for secondary service, can use flexibly in actual operation process to obtain a suitable result.

Obtain can to obtain the code check matrix of each business need minimizing after weight matrix and the statistics, more than routine data:

$\mathrm{WF}=\left\{\begin{array}{ccc}\frac{3}{6}& \frac{2}{6}& \frac{1}{6}\end{array}\right\}\left\{\begin{array}{ccc}3\mathrm{kbps}& 0& 0\\ 1\mathrm{kbps}& 1\mathrm{kbps}& 0\\ 1\mathrm{kbps}& 5\mathrm{kbps}& 5\mathrm{kbps}\end{array}\right\}=\left\{\begin{array}{ccc}\frac{12}{6}\mathrm{kbps}& \frac{7}{6}\mathrm{kbps}& \frac{5}{6}\mathrm{kbps}\end{array}\right\}$

Having introduced three kinds above adjusts strategy and adjusts the adjustment that strategy carries out according to three kinds; be appreciated that; be combined into the technical scheme that a kind of combined strategy can be finished the embodiment of the invention equally mutually by adjusting strategy in the embodiment of the invention with three kinds; and can not enumerate all among the embodiment and adjust tactful situation, those skilled in the art adjusts strategies by other that read that embodiments of the invention can also expect and also should think and be included within protection scope of the present invention.

Introduce headend equipment below and how to carry out the adjustment of broadcast strategy according to top adjustment strategy:

After weights on obtain are adjusted matrix, combine the parameter information S of current all broadcast business datum by front end system, after weight matrix W and the feedback information matrix F, every kind of professional actual play code check S ' just can obtain according to following formula:

S′＝S-WF( $\underset{i=1}{\overset{n}{\mathrm{\&Sigma;}}}{S}_i^{\&prime;}<T_{\max },$ T wherein _MaxMaximum stream flow for the radio network permission)

For example: if according to the employing of front according to the customer complaint ratio of setting, when current business was broadcast parameter and adjusted strategy, current headend equipment to the data matrix S of each sending down service was:

S=[587], after having obtained the sending down service speed that needs to adjust, that is:

$\mathrm{WF}=\left\{\begin{array}{ccc}\frac{12}{6}\mathrm{kbps}& \frac{7}{6}\mathrm{kbps}& \frac{5}{6}\mathrm{kbps}\end{array}\right\}$

Each service rate that issues after the adjustment that like this, finally obtains is:

$S\&prime;=S-\mathrm{WF}=\left[\begin{array}{ccc}5& 8& 7\end{array}\right]-\left[\begin{array}{ccc}\frac{12}{6}& \frac{7}{6}& \frac{5}{6}\end{array}\right]=\left[\begin{array}{ccc}3& \frac{41}{6}& \frac{37}{6}\end{array}\right]$

So the speed that issues to each business that finally obtains is: $3\mathrm{kbps},\frac{41}{6}\mathrm{kbps},\frac{37}{6}\mathrm{kbps}.$

Adopt above the professional speed of broadcasting in the DVB system is adjusted into example, be appreciated that, can also be by service related information to each terminal equipment in the current DVB system, select whether to throw in a certain business, for example: according to the explanation of front, each terminal equipment forward end equipment in the DVB system upload terminal equipment CPU operating position and when playing current business, the operating position of internal memory, by these information, headend equipment can obtain for a certain professional based on the mode of statistics, whether the terminal equipment of common configuration level can receive this program, broadcast strategy adjustment for business that can be above the clearer explanation is exemplified below:

Test by headend equipment, play a certain class HDTV (High-Definition Television) program, at least need the internal memory of terminal equipment to reach 1G, each terminal equipment by the DVB system is added up by the service related information that feedback path is uploaded to headend equipment, the terminal equipment that obtains current 60% user all can not reach this configuration level, like this, headend equipment is handled service source information accordingly with regard to needs consideration employing, reduce the code check of encoding and decoding, reduce the use of business, satisfy the broadcast condition of each terminal equipment the internal memory of terminal equipment.

Again for example: terminal equipment can also be adjusted the broadcast of the business of headend equipment by the use habit that detects the user, for example: detect temporal information and the programme information that the user watches the business that headend equipment issues by each terminal equipment, and then statistics obtains the user's of DVB system use habit, and then, regulate the broadcast moment of different programs according to above-mentioned statistics.For example: at 20:00-22:00, the information of uploading by the terminal equipment of DVB system, statistics obtain 60% user this section period more watch the TV play channel, like this, the broadcast that playback level by improving the TV play channel or priority are adjusted program.

Be appreciated that; add up the business information of each terminal equipment and then adjust professional broadcast; the relevant amount to be adjusted of business that also may comprise other; present embodiment mainly adopts adjusts professional playback rate; professional playback level etc. illustrate the realization of the embodiment of the invention for example; other are relevant passes through statistics to the service related information of the terminal equipment of DVB system; and then the technical scheme that the business of adjusting headend equipment is play also is to be included in the protection range of the embodiment of the invention; as space is limited, embodiments of the invention repeat no more other similar scheme.
