Abstract
The invention discloses a method for sending dunning information of a digital television, comprising the steps that: while user defaulting data is broadcast and sent in an object carousel mode, a dunning notification message is sent in a mode of instantaneous screen display/television short message, the user is reminded at each frequency point of a set top box in a mode of rolling letters or mails, and the user switches to a corresponding frequency point at any time to browse defaulting data. The technical scheme can reduce the sending amount of dunning information of the digital television and improve the hit rate and validity of reaching of the dunning information.
Description
Technical field
The present invention relates to the digital television techniques field, relate in particular to the method that a kind of dunning information of digital television sends.
Background technology
Along with China numerous cable network operator successively enters after the Digital Television turn over period, the connotation and extension of Digital Television is also among continuous development.On the one hand a large amount of networked users remain the one-way digital television user, and the assets of cable network operator maximum are exactly frequency spectrum and bandwidth on the other hand.How to improve the utilance of cable network resource under the unilateral network prerequisite, improve operation, service level and quality, making the interests maximization is the problem that each operator generally faces.
Existing data broadcasting in the one-way digital television system, EMS and instant screen show/and television short message means such as (Camail/OSD) press for payment of the user that role can not be ignored aspect the expense, but there are defective and deficiency simultaneously separately again, single kind means all can't reach gratifying effect at aspects such as bandwidth, speed, hit rate, validity comprehensively, become the bottleneck place of promoting the use of, both made the user on probation, it is not high to accept degree of recognition yet.So-called herein " hit rate " is meant the user in limited available machine time every day, and message is guaranteed the probability sent to.Send to simultaneously and might not be noted, " validity " is meant that then message is sent to the back and paid close attention to and know by the user.
Usually press for payment of charge system and the digital television business OSS communicates by interface.And write down, be maintained in the network users information material is the indispensable inherent requirement of OSS, also be that OSS is good at part the most, thus for to specific user's impression information and service content, carry out customer information and excavate the feasibility infrastructural support is provided.
The mode of traditional issuing message has following several in the Digital Television: Camail/OSD, EMS, data broadcasting etc. are several.Wherein the Camail/OSD mode can be stored in the set-top box end, at any one frequency as seen, EMS can display by screens on the channel of appointment, and data broadcasting (substantially all tends to adopt object carousel (Object Carousel at present, OC) protocol mode) need equally to receive on the frequency of appointment, both can't be preserved the back at the set-top box end at present.Because the transmission of Camail/OSD need be passed through condition receiving system (CA), increased processing expenditure greatly, and every information has length restriction, can not surpass 256 bytes such as every message-length, cause transmission speed slow, usually and be not suitable for that Large Volume Data is point-to-point broadcasts, the prerequisite that effectively be utilized is to carry out data compression.Both shortcomings of back also clearly, the set-top box end is not preserved, if the user starts shooting broadcasting at that time, does not then expiredly wait.But the assignable bandwidth of data broadcasting can be very wide, is used for data broadcasting such as one or several frequency of specific assigned.The OC protocol mode is supported to send data with the file packing manner.The characteristics of these several modes are to such as table 1 (representative value):
Table 1
Is example with certain operator to the charge system of pressing for payment of of five kinds of running costs such as user's water, electricity, gas, wired license fee, broadband access fee, presses for payment of by digital television system.This provincial operation system leading subscriber number reaches 3,000,000, but with districts and cities for pressing for payment of management subject unit of operation, each districts and cities carries out differentiated control as the branch center, districts and cities' maximum can be managed 50 general-purpose families.Therefore can set up the independent charge system of pressing for payment of in each districts and cities branch center, to adapt to the different demand of each districts and cities, the processing pressure of while center of dispersal.
User's request: in the short as far as possible time, send information as much as possible, and guarantee to send to rate and validity.
Available resources: headend equipment and frequency resources such as characteristic informations such as user property, Camail/OSD, EMS, OC data broadcasting, CA, each model set-top box that the user has allotted or bought.
Amount of information: if send the expense of pressing for payment of for each user, the information of each CU certain-length byte (out of Memory field can expand press for payment of type), message frame content such as table 2:
Table 2
| Frame head | IC-card number | The charge type sign | The amount of money (unit: divide) | Out of Memory | Verification (standby) |
| ??2 | ??16 | ??1 | ??10 | ??50 | ??2 |
Handle as not adding compression, then the byte number of the required transmission of each user: the 4+16+11*5+50=125 byte.
The about 60M of 50 general-purpose family total amount of data.Send by different modes, required time is respectively:
OC: about 2 seconds
EMS: about 1.8 hours
Camail/OSD: about 18 hours
Suppose that the user started shooting 1 hour every day, then OC/DC mode hit rate reaches 100%, EMS be hit rate less than 60%, the Camail/OSD mode is minimum, most users almost do not receive in the available machine time.
Therefore for the back both, as improving hit rate, perhaps increase headend equipment quantity such as CA, increase concurrency, but the cost too expensive; Perhaps can the compressed message frame, reduce amount of user information, but under the prior art condition, only to reach the text data compression ratio of tens times even hundreds of times by universal compressed algorithm, also there is technical difficulty.
Though OC mode hit rate is high, but hit rate and be not equal to efficient because the OC mode is specifying frequency to send, if untimely this frequency that switches to of user still can't in time be known this message.Simultaneously a lot of turn over time old type tube set-top box early also can't be supported the real-time processing of a big file of 30M.
Summary of the invention
The objective of the invention is to propose the method that a kind of dunning information of digital television sends, can reduce the traffic volume of dunning information of digital television, improve hit rate and validity that dunning information is sent to.
For reaching this purpose, the present invention by the following technical solutions:

Embodiment
Further specify technical scheme of the present invention below in conjunction with accompanying drawing and by embodiment.
The main thought of technical solution of the present invention is based in the digital television system, it is slow that addressing system sends information rate, but validity height, non-addressing system sends the information rate height, but validity may be very low, therefore takes in OC mode broadcast transmission subscriber arrearage data, sends in the CaMail/OSD mode and press for payment of the expense notification message, each frequency in set-top box is reminded the user with roll letter or lettergram mode, and the user switches to frequency points corresponding at any time and carries out browsing of arrearage data.
Fig. 1 is the flow chart that dunning information of digital television sends in the specific embodiment of the invention.As shown in Figure 1, this dunning information transmission flow may further comprise the steps:
Receive to handle the expense of the pressing for payment of notification message that sends in the CaMail/OSD mode and during for making set-top box with the subscriber arrearage data of OC mode broadcast transmission, can judge in advance according to the user characteristics sign indicating number, reduce and search for match time, need carry out the preparation work that user characteristics is encoded and issued the user characteristics sign indicating number in advance, the user characteristics sign indicating number is forever preserved in set-top box, when buying band card set-top box, preset to user dispensing or user, when changing set-top box card or change user profile, replacement user characteristics sign indicating number.
The effect of user characteristics sign indicating number is can be whereby to specific user's pushed information and service, can play simultaneously and reduce set-top box end search time, reduces set-top box processes pressure.
The user characteristics sign indicating number can be the user property that user area sign indicating number, subscriber segmentation type coding, VIP type codes, town and country identity code, type of credential coding, local office number or mobile phone section etc. have write down in OSS, can carry out Combination Design as required.According to existing CA interface specification, the user characteristics sign indicating number is divided into 4 parts, and the longest 3 bit digital of every part are formed.Number as separator, first can represent the zone with "-", and second portion is represented user type, and third part is represented the VIP sign, and the 4th part is represented local office number or number section, and length is distributed 2-2-2-3 respectively, totally 9 bytes.As the user characteristics representation that is numbered 1-2-3-133 to regional code be 1, user type is encoded to 2, VIP is numbered 3, the phone number section is that 133 specific user sends.Each several part definition and coding rule table can be customized according to above-mentioned rule voluntarily by the user.Complete 0 as condition code, expression is regardless of user characteristics and all sends.
Therefore because for most users, expenses such as water, electricity and gas, license fee are daily indispensable, and each user can have such expense in every month basically, and according to general knowledge, what do not have expense only accounts for minimum part.Therefore when the expense notification message is pressed for payment of in transmission, do not send the user profile of arrearage bill, and only send the user profile of no expense, if not having expense user proportion is 5%, the data compression rate of then pressing for payment of the expense notification message can reach 20 times.
Under the actual conditions, the few on the contrary phenomenon of the number of users of arrearage expense (when paying pre-payment in year, have only arrearage is just arranged when user's amount is finished using) might be arranged also, then can send at the user that the arrearage bill is arranged and press for payment of the expense notification message this moment.
Based on above-mentioned condition, press for payment of expense notification message total amount of data in the further compression of mode that transmitting terminal can be taked to send part subscriber arrearage information flexibly as required, under the worst case, also can reduce the data volume (promptly only needing to send 25 general-purpose family information wherein in the 50 general-purpose families) of half.When all networked users owe charge information, need not to send one by one card number, the arrival notice symbol of pressing for payment of that only needs to send special definition gets final product.Therefore, can be implemented in fully and will press for payment of the expense announcement information in 1 hour and send and to finish.
Fig. 2 is a structure chart of pressing for payment of the expense notification message in the specific embodiment of the invention.As shown in Figure 2, press for payment of and comprise frame type, user characteristics sign indicating number, identifier, arrearage sign, set-top box card number and check code in the expense notification message frame, wherein identifier is used to represent to be the expense of the pressing for payment of notification message that the defaulting subscriber is arranged, and does not still have expense user's the expense of pressing for payment of notification message.
Press for payment of the expense notification message for every and be no more than 256 bytes, each user's amount of information 16 bytes (being card number length), remove frame head (comprising frame type, condition code, identifier and arrearage sign) and the shared length of check field, length available is the 256-1-9-1-1-2=242 byte, and it is about 30 that the card number quantity that can comprise through every the message in 50% compression back rounds the back.Worst condition is 4/second as the OSD/CaMail transmission rate down, and then required time is 250000/30/4, less than 40 minutes, is 3/second as transmission rate, then needs about 46 minutes approximately.
Add user characteristics sign indicating number and arrearage message flag symbol or do not have expense message flag symbol according to defaulting subscriber's ratio before sending.Raw information was according to the processing of sorting of card number affiliated area, card number before compression was handled.Pressing for payment of start frame of the first frame increase of expense notification message, in the end a frame increases end frame (distinguishing start frame, end frame and other content frame with flag of frame), judges whether display reminding information immediately in view of the above in order to set-top box when the no expense user of transmission presses for payment of the expense notification message.This is just can send one time within a period of time because press for payment of the expense notification message, if do not have this start frame and end frame, as the not arrearage of this set-top box users, because the relation of time difference, not preceding several pressing for payment of in the expense notification message, set-top box can't judge whether the announcement information of explicit user arrearage immediately as card number.
Content by pressing for payment of expense notification message frame in every frame, has a large amount of redundant informations as can be known, and different frame has information redundancy equally, adopts data compression algorithm to significantly reduce to need the data volume that sends.General lossless compression algorithm commonly used has huffman coding and LZW compression method.
Press for payment of expense notification message frame as can be known by analysis, because user's card number has certain continuity, after descending or ascending sort, the announcement information redundancy of being made up of continuous card number information will increase substantially, and compression ratio also can improve thus.
Huffman coding is based on the information theory entropy theory, to the coded representation with minimum length of the character of probability of occurrence maximum, reaches the purpose of Information Compression.
The string list compression method has been adopted in the LZW compression, and each string that occurs for the first time is placed in the string list (dictionary), and dictionary can restore during decompress(ion).
As the card difference that is numbered 63070003615A14F6 and is numbered 63070003615B14F6 has only a character, by statistics all card numbers through the repetition rate of adjacent two card numbers in ordering back greater than 75%.For the very high text of this type of repetition rate, compression effectiveness is better.
Press for payment of 16 card numbers that only need in the expense notification message frame to send fixed length and carry out addressing for set-top box, so according to the CaMail/OSD transmission rate, do not add the compression per second and can send about 50 users, the time that 50 general-purpose families need to send altogether is 10000 seconds (3 hours).Before message sends card number is sorted, compress the back packing and send, because the continuity of card number, the compression ratio that reaches more than 50% is guaranteed.
In addition, for mating fast at the set-top box end, the user characteristics sign indicating number does not compress.
Fig. 3 is a subscriber arrearage file content schematic diagram in the specific embodiment of the invention.As shown in Figure 3, the subscriber arrearage file has comprised multiple information such as address name or user's card number, charge type, Fee Amount, and the set-top box end mates by card number, and the resolution file content is obtained corresponding dunning information.
Simultaneously, must there be user area information in the perfect OSS,, can comes the named file name, perhaps point out whether contain the subscriber arrearage data in this document with the card naming method by zone number for reducing the processing expenditure of set-top box end.The former is applicable to the occasion (can in advance area information be write set-top box) of the area information that prestored in set-top box; The latter can be earlier resolves in this document whether contain subscriber arrearage information by filename, as otherwise this set-top box this document is not further understood.Therefore, at transmitting terminal, can press for payment of total amount of data according to channel width, set-top box buffer memory capacity, disposal ability and user cuts apart, subscriber arrearage data branch is installed to a plurality of files the inside to be sent, according to the method for zone-card number mixing named file name, reach and improve the purpose that transmission and receiving efficiency, reduction set-top box end are handled bottleneck to the full extent.
Compression ratio according to 50%, the 60M data compression is 30M, each arrearage file is limited in (generally existing set-top box internal memory is enough to provide required buffer memory capacity, as the set top box upgrading difficulty, can alleviate processing pressure by the method that further reduces single arrearage file size) within the 2M.Be divided into 15 zones as this area, then be divided into 15 arrearage files and take turns and broadcast.Filename mixes name with zone and card number start-stop numbering, and the start-stop zone of zone number can be identical.As:
63070003615A14F6_630700036F6F14F6@1_2_3_4.txt
Being the start-stop card number before @ number, is the user characteristics sign indicating number after number, and it is that the user that 1_2_3_4 and card number drop in 63070003615A14F6 to the 630700036F6F14F6 scope sends information such as arrearage data that this document name is represented to the user characteristics sign indicating number.
So another benefit of name is can carry out orientation according to conditions such as particular user types, regions easily to press for payment of, and has increased the flexibility of pressing for payment of charge system.
For pressing for payment of the expense notification message, mate according to the user characteristics sign indicating number earlier,, continues the machine owner identification next step (not processing) if conforming to otherwise abandon this frame.Set-top box parses the flag of frame symbol then, if the defaulting subscriber presses for payment of the expense notification message, then follow-up card number data are decompressed earlier, again the message behind the decompress(ion) is carried out the step-searching coupling of fixed length formula (card number is fixed as 16), as overlapping with this machine card number, promptly eject information, notify the user to switch to the exclusive data broadcasting channel and browse the arrearage data, the subsequent notification messages frame is abandoned no longer and is handled; If there is not defaulting subscriber's notice, receive that then first is provided with the opening flag position when pressing for payment of expense notification message frame, resolve one by one, if this machine of matching card number, then be provided with and finish flag bit, subsequent frame is abandoned no longer and is handled, if former frame does not match this machine card number, then continue to receive subsequent frame, up to notified end frame.As do not match card number during this period always, then receive Pop-up message information after the end frame, notify the user to switch to the exclusive data broadcasting channel equally and browse the arrearage data.
If the card number of step 112 set-top box in arrearage file filename in the set-top box card number start-stop value scope, then with oneself card number and the arrearage file in the card number of arrearage data mate, if coupling then reads the arrearage data, and show the arrearage data.
Also promptly, after set-top box is received the arrearage file, mate by filename earlier,, then abandon this document, continue to handle next file as inconsistent with machine master user characteristics sign indicating number; If user characteristics sign indicating number coupling, and during this machine card number drops between the filename location, then file being decompressed is mated content and this machine card number wherein,, continue next file of processing otherwise abandon if match then take out and show relevant information.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with the people of this technology in the disclosed technical scope of the present invention; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection range of claim.
