Carrying out the synchronous process of TV guide also can be: when the station synchronization Single-Server changes in self-contained up-to-date TV guide, MMU parts in the media center server send up-to-date TV guide on one's own initiative, after the up-to-date TV guide that the station synchronization Single-Server sends here is received at the stream medium data center, upgrade the TV guide of current preservation with up-to-date TV guide.In addition, the station synchronization Single-Server periodically with the media center server in the MMU parts keep heartbeat message.This heartbeat message is used to guarantee that the MMU parts can know that communicating by letter between MMU parts itself and the station synchronization Single-Server is normal.
In step 42, the user can adopt following three kinds of modes to send TV programme customization request to the stream medium data center: customize, customize by the STB customization with by short message by Portal.Below above three kinds of methods are described respectively.
1, customize by Portal: this kind mode mainly is the customization page that is provided by visit Portal parts, select the required TV programme clauses and subclauses of user to customize, therefore, use the prerequisite of this kind method for customizing to be: the user needs the terminal that can surf the Net, this terminal can be ordinary individual's computer (PC) terminal that is linked among the Internet, also can be the portable terminal that inserts CDMA-1X or GPRS network.The detailed process that customizes by common PC terminal may further comprise the steps as shown in Figure 6:
Step 61: user's TV programme customized web page that the user is provided by the Portal parts the browser access media center server on the PC terminal, such as:
http://portal.cctv.com.cn/pc/customization.jsp。
Here, the user to import the action of http://portal.cctv.com.cn/pc/customization.jsp be that the user asks.
Step 62: after the Portal parts in the media center server receive that the user asks, read background data base, after the taking-up information datas such as TV guide content and arrangement wherein, be sent on user's the PC terminal.
Step 63: the user browses up-to-date TV guide content by this user's TV programme customized web page, chooses the TV programme clauses and subclauses of oneself wishing customization by the click mode and generates the customization request, and be submitted to the media center server.
Step 64: after the Portal parts in the media center server are received user's customization request, it is joined in the task processing queue of MMU parts, wait for the processing of MMU parts.Here, suppose that above-mentioned Client-initiated customization request is legal.
Step 65: the Portal parts in the media center server receive customization processing of request result to user's retrieval system, with notice customization success or not, for example, can return to the user: " eight steps of day dragon " that you customized enter into force, and please watch when the time comes.
The user is basic identical by process and said process that the portable terminal of supporting the WAP online customizes, its difference only is: the former is to use PC terminal etc. to be connected through the internet to the Portal webpage, the latter is to use portable terminal by supporting the mobile network of mobile terminal WAP business of networking, is connected to the Portal webpage such as mobile dream network (Monternet).From customized web page demonstration, customization process and background process process, the two is similarly, even can be identical.Therefore, the process that customizes by mobile phone is at this repeated description no longer.
2, customize by STB:
Basic procedure by STB customization may further comprise the steps as shown in Figure 7:
Step 71: the television set and the STB of user side are powered up, and the browser of STB sends the request of reading TV guide information by the Portal parts of network in the media center server.
Wherein, after television set and STB power up, the STB EPG framework of at first can packing into, the EPG framework is the page that EPG provides, be similar to the WEB page that WEB SERVER provides, but do not comprise the content in the page, after the EPG of browser in the Portal parts of STB initiated to read the programme request, just the electronic program list information that EPG is provided was presented in the EPG framework.
Step 72: the Portal parts in the media center server read TV guide information from background data base, return to the browser of STB by network, are shown to the user by the user side television set.
Step 73: the remote controller of user by STB need to select the TV programme of customization from TV guide information, confirms also to submit to the TV programme of own customization, generates to customize and asks to send to the media center server.
Step 74: after the Portal parts in the media center server are received the customization request, that the customization request is medium pending as the task processing queue that customized task joins the MMU parts.Here, suppose that above-mentioned customization request is legal.
Step 75: the Portal parts in the media center server receive the request result of customization demand with system, are notified to the user, for example, can return to the user: " eight steps of day dragon " that you customized enter into force, and please watch when the time comes.
3, customize by short message: the mode by the short message customization generally is applicable to the customization of occasional nature.Adopt a precondition of this kind customization mode to be: the user is known to be needed the television program transmission time of customization and broadcasts channel.For example, if the time period of CCTV1 20:30～22:10 in evening is broadcasted TV series " conquering ", the user just can send the short message of following content so: " 2004122820302210 CCTV1 " is 8888 to specific Short Message Service number such as the Short Message Service number.The implication of this short message is: customize and divided the programme content that broadcasts at CCTV1 on December 28th, 2004 from 20:30 to 22:10.Perhaps, the user also can send the short message of following content: 200,412,282,030 100 CCTV1, the implication of this short message is: customize programme content in 100 minutes that began from 20:30 on December 28th, 2004, that broadcast at CCTV1.
The following describes the detailed process of short message customization flow process, as shown in Figure 8, suppose that program customizing Short Message Service number is 8888, and the utilization merchant of system of the present invention applied to become VASP, specifically may further comprise the steps:
Step 81: user's format editing short message according to the rules sends to Short Message Service number 8888.
Step 82: the purpose side that Short Message Service Center identifies the short message of issuing Short Message Service number 8888 is behind the Portal parts in the media center server, by the SMPP agreement this short message is gone to Portal parts in the media center server.
Step 83: after the Portal parts in the media center server were received user's short message customization request, it is medium pending that the task processing queue is asked and joined in the analysis customization.Here, suppose that above-mentioned customization request is legal.
Step 84: the Portal parts in the media center server send the successful short message of customization by the SMPP agreement to the user.
The TV programme that above-mentioned customization mode is customized can customize according to content of TV program, also can customize according to the TV program time section.Wherein, customize to be meant with the content to be the customization that index key carries out, be also referred to as the clauses and subclauses customization according to content of TV program.Customize to be meant with the time period to be the customization that index key carries out according to the TV program time section.Particularly, customized web page is by being similar to the mode of TV newspaper TV guide, showing in the TV guide to the user to comprise information such as channel, programme content and broadcast time, is that CCTV1, TV programme are that lucky 52, reproduction time is 20:00～21:00 such as channel.If the user is carrying out TV programme when customization, indicate the programme content that will customize CCTV1: lucky 52, then this mode customizes according to content of TV program exactly.Relative, if the user indicates the time period 20:00～21:00 that will customize CCTV1 when carrying out the TV programme customization, then this mode is for to customize according to the TV program time section, though the result of latter's customization also is lucky 52.
Above in the described scheme, after the Portal parts in the media center server receive the program customizing request message, to the concrete operations of customization request as shown in Figure 9, mainly may further comprise the steps:
Step 91: the Portal parts in the media center server are submitted to the program customizing request message of receiving the MMU parts as customized task and handle.
Wherein, judge whether legal condition comprises customized task: judge to send whether the customization requesting users is the registered user, whether the form of customization request is correct, require the TV programme of customization whether in programme, to exist in the customization request, whether customization request is the same request that same user sends, and whether the television program transmission time that requires customization in the customization request mistake, when satisfying above-mentioned condition, then customized task is legal, otherwise customized task is illegal.
Step 94～95: the MMU parts in the media center server join legal customized task in the task processing queue, activate customized task at special time, promptly the MMU parts send record command to encoder and record specific TV programme to notify encoder to encode.For example, if customization the program of 20:00, so, this customized task will be activated at 20:00.Wherein, the task processing queue is used for preserving the customized task that can record.
Step 96: after encoder was received the record command of the MMU parts transmission in the media center server, the TV programme that requirement is recorded to customized task was encoded and is recorded, and after customized task was finished, encoder sent Mission Accomplishment Report to the MMU parts.
Step 97: after the MMU parts in the media center server are received Mission Accomplishment Report, the task performance is written in the background data base of Portal parts, such as institute's customizing programming corresponding file title, path etc., system is the URL in each customization task generation MyPortal page separately, and upgrades this user's individual character door (MyPortal).
In the said process, the situation that different user need be recorded identical TV programme may occur,, prevent to repeat to record, the invention provides preferable processing mode in order to save memory space.Be elaborated below.
Because customization mode provided by the invention comprises mode that customizes according to content of TV program and the mode that customizes according to the TV program time section, the situation that following two kinds of repetitions therefore, will occur: a kind of is the repetition of the customization request content of initiating according to content of TV program; Another kind is the repetition according to the customization request content of time period initiation.These two kinds of customized tasks that may occur repeat can handle in the following manner respectively:
When customization request during for the customization request initiated according to content of TV program, the stream medium data center judges whether this customized task content is identical with the current customized task content that is in the task processing queue, if it is identical, then this customized task is not joined in the task processing queue, if inequality, then this customized task is joined in the task processing queue.
When customization request during for the customization request initiated according to the time period, the stream medium data center judges whether this customized task time period and the current customized task time period that is in the task processing queue have repetition, if do not repeat, then this customized task is joined in the task processing queue, if repetition is arranged, then judge whether to repeating fully, if repeat fully, then this customized task is not joined in the task processing queue, if not repeating fully, then merge, produce the customized task that comprises each time period set sum, join in the task processing queue with this customized task with the incomplete customized task that repeats of its free section.
For example, for first kind of situation: suppose that two user A and user B carry out the TV programme customization, suppose that user A initiates the request of customized content contentl earlier, this moment, whether system was legal according to process analysis user request shown in Figure 9, suppose that this request is legal, whether then the MMU parts are searched background data base has content1 to repeat, and supposes not repeat, it is pending then this customized task to be put into the task processing queue, and returns the information of " successfully subscribing to " to the user by the Portal parts.
After this, user B has also initiated the request of customized content content1, similarly, user's request that system docking is received is analyzed, and it is legal to judge whether, suppose that judged result is legal, then begin to search background data base, find wherein to comprise content1, so customized content repeats, system was not put into this customized task in the task processing queue and handled this moment, but still returned the information of " successfully subscribing to " to the user by the Portal parts.
For second kind of situation, suppose that user A at first subscribes to the content of T1～T2 time period, and system admits the customization request and returns success subscription information according to above-mentioned handling process; User B initiates to subscribe to the content of T3～T4 time period subsequently, if it is legal to ask, then system can return to the user and subscribe to successful message, but system need further judge whether this task is put in the task processing queue, need handle according to the situation that the time end repeats, this moment, system handles was as follows:
Repeat situation owing to consider the time period, therefore do not consider T4 smaller or equal to T1, perhaps T3 is more than or equal to the situation of T2.If T1≤T3 and T2 〉=T4, this task is not put into the task processing queue so, and only being increases the project that user B subscribes in background data base; If less than T4, user B tasks requested is not put into the task processing queue to T1 so greater than T3 or T2, but will revise the task of the user A customization in the task processing queue, T1 is revised as Max{T1 with the time started, T3}; Concluding time T2 is revised as Max{T2, T4}.Like this, encoder just begins recording time section: Max{T1 after receiving record command, and T3} is to the content of TV program between Max{T2, the T4}.Wherein, Max is for getting maximum operation.
Though these two customization request contents are merged,, the raw requests data that the user sends can not lost by system, still can be according to user's raw requests data record user customized information.That is to say that system still can indicate customization task time started and the concluding time separately respectively in database.For example, the time period of user A still is T1～T2; The time period of user B still is T3～T4.
After this, if being arranged again, third party C request records the content of T5～T6, the handling process of system is with top identical: still need to revise zero-time and concluding time in the top task processing queue, time started is revised as: Max{Max{T1, T3}, T5}, the concluding time is revised as: Max{Max{T2, T4}, T6}.Subsequent user is arranged later on again, and handling process is with top identical.
Because the overlapping different user customization request of free section will cause the merging or the modification of customized task, therefore, will preserve a content of TV program file corresponding to this customized task execution result.As described previously, because system can write down each user's initial sum dwell time respectively, so system will read the beginning and ending time separately, and it joined among the URL being each customization task when generating URL in separately the MyPortal page from database.Like this, the user is when clicking the TV programme that oneself customizes by remote control equipment, and parameter is exactly different in the playing request message that different users sends.
For example: user A and user B have customized the content of TV program of CCTV1, but the beginning and ending time section of customization is respectively T1～T2 and T3～T4, supposes T1＜T3＜T2＜T4, suppose that customized task after this merging records the result and save as filel.wmv.
When carrying out the TV programme broadcast, the playing request that the set-top box of user A is uploaded can be:
rtsp://media/path/play?user=A&channel=cctv1&start=T1&end=T2
The playing request that the set-top box of user B is uploaded can be:
rtsp://media/path/play?user=B&channel=cctv1&start=T3&end=T4
The file that is read from the HMS parts, that two set-top box read all is same file f ilel.wmv, when but the HMS parts are play to user A, be that 0 time offset from file f ilel.wmv begins to read, and the HMS parts are when user B plays, and then { side-play amount of T3-T1} begins to read and play to user B's from file f ilel.wmv.
In addition, if the user need cancel the TV programme customization request that oneself has sent, also can send and customize request mode, but order wherein is the request of cancellation customized task by above-mentioned three kinds.After the Portal parts will receive that the request of cancellation customized task is transmitted to the MMU parts, the MMU parts were wanted the record in the analytical database, judge the district in two kinds of situation:
A kind of situation is that the customized task that system has admitted is unique user task of this user, after this moment, the MMU parts were received the request of cancellation customized task, judge whether the customized task that will cancel in the request of cancellation customized task belongs to the customized task in the task processing queue, if, then this customized task is deleted, and returned customized task to the user and cancel successfully; If not, then the MMU parts compare current completed customized task in the customized task that will cancel in the customized task request and the Portal parts background data base, judge whether the customized task that will cancel in the customized task request is completed customized task, if, then return customized task and finish, can't cancel to the user; Otherwise return to the user and need not to cancel operation.
Another situation is that the customized task that system has admitted is not unique user task of this user, and this moment, the MMU parts needed Query Database, if this customized task is finished, then returned to user task and finished, and can't cancel; Otherwise, the associated custom task in the change task processing queue.The processing logic of customized task was similar when the logic of change associated custom task and the free section of multi-user noted earlier were overlapping, no longer repeated at this.Similarly, recognize after task in the processing queue finishes, return to the user and cancel success in change.
Except cancelling the customized task that has sent, the user can also inquire about oneself ordered content of TV program.When customizing the inquiry of TV programme task, the order that the user sends is the current customized task of inquiry, after the MMU parts are received querying command, need arrive in still untreated task processing queue and the completed customized task database and inquire about, then Query Result is returned to the user.If inquire about the current TV programme of recording of having finished, then only need in completed customized task database, to inquire about, then Query Result is returned to the user and get final product.The user can also can inquire about by sending SMS message by PC terminal and mobile terminal Internet access inquiry.Detailed process is similar with sending the customization request mode, and difference only is the operational order difference that sends.
In the step 43 of Fig. 4, the detailed process of the programme content that customer consumption customized may further comprise the steps as shown in figure 10:
Step 101: after the television set of user side and STB power up, STB reads by network that user in the Portal parts background data base in the media center server is used to carry out the TV programme customization and the data at the information interaction interface of playing, and information such as electronic program list are presented on the television set.
Step 102: the user selects the MyPortal option in the information interaction interface, after choosing the MyPortal option, after Portal parts in the media center server are received request, checking user profile, if user profile is proved to be successful, the TV programme items for information that then reads this customization in the background data base is presented in the MyPortal interface of television set, if any TV programme of this user's un-customized, then displaying contents is empty; If the user profile checking is unsuccessful, then show the disabled user.
Step 103: the programme content of selection and submission oneself customization in the TV programme items for information that has customized that the user lists from the MyPortal interface, for example choose " Discovery) ", generate playing request, send to the media center server.
Step 104: after the Portal parts in the media center server are received user's playing request, verify user profile once more, after the user profile checking is passed through, the Portal parts send redirect message to user's set-top box, comprise the agreement of visit HMS parts, IP address, content of TV program information and the user authentication information encryption string etc. of HMS parts in the redirect message, wherein, the agreement of visit HMS parts generally is the RTSP agreement.
Step 105: after user's STB receives above-mentioned redirect message,, initiate to comprise the playing request that is redirected of content of TV program information to the HMS parts such as the RTSP agreement automatically by corresponding access protocal.
After the playing request after step 106:HMS parts are received and are redirected, STB by RTSP agreement and user side carry out the RTSP protocol information mutual after, beginning sends the content of TV program data flow to user's STB, promptly play the content of TV program of being recorded to the user, and begin to charge by the mode of stream.Wherein, whether be optionally, can carry out according to operator's rule if chargeing and how to charge.The RTSP protocol information is meant that alternately the internal information of RTSP protocol specification regulation is mutual, comprises the mutual of a lot of complexity, does not repeat them here.
Consider that the user repeatedly plays the situation of same TV programme, after the TV programme broadcast end that once request is play, the broadcasting time of setting in the time of need be according to customization is operated, revise the customized information of this user in database, by a broadcasting time that successively decreases consumer premise, judge whether current broadcasting time is zero, if be zero, then the HMS parts will notify the MMU parts to delete this content of TV program; Otherwise preserve the result that successively decreases.Such as, if the user has selected N broadcast when customization, the HMS parts are revised as N-1 with the record in the database from N after once finishing playing so; When N-1=0, the HMS parts will notify the MMU parts to delete this content of TV program.
Perhaps, need also can determine whether this content of TV program of deletion in the following way: the current broadcasting time of the accumulative total TV programme of playing, judge that whether the broadcasting time accumulated result is identical with the broadcasting time of consumer premise, if identical, then deletes this content of TV program; If inequality, then preserve the broadcasting time that current accumulative total obtains, as the accumulative total radix of playing next time after finishing.
More than revising broadcasting time to determine whether to delete the process of the content of TV program of being play, is only to be that a TV programme that the user was customized is a prerequisite with a certain content of TV program.Customize the situation of a content of TV program simultaneously for a plurality of users, whether delete this content of TV program and need then to analyze whether all users had watched this content of TV program, if all users that customize this content of TV program had watched this content of TV program in the system database, be that the current broadcasting time at all booking readers of this content of TV program all is 0 in the subscription database, the HMS parts will notify the MMU parts to delete this content of TV program corresponding file so; Otherwise reservation this document had been watched this content of TV program all up to all users.
Above-mentioned playing process is finished by audio ﹠ video equipments such as set-top box and television sets, certainly, also can play by personal computer terminal.If following mobile network's transmission rate reaches requirement, can certainly adopt portable terminal to realize the broadcast of personalized television program.
By such scheme as can be seen, customizing content of TV program system and method provided by the invention can be when the user can't watch the situation of TV and no worker monitor, and the television program record of individual preference is got off, and realizes carrying out television program record whenever and wherever possible.And system and method provided by the invention not only can shift to an earlier date pre-recording, can also record simultaneously the TV programme of a plurality of television channels.In addition, because the storage mode that the present invention program provides can be realized sharing of resource, and the subordinate that can realize centralization, therefore, the user can consider the restriction of memory space, thereby realizes mass memory.
And, in the early stage of development of customizing content of TV program business provided by the invention, can only adopt single stream medium data Centroid to satisfy business demand, but growth along with traffic carrying capacity, service node can not only be confined to the stream medium data center, also the HMS parts at stream medium data center can be carried out distributed deployment to realize the support to high traffic.
In a word, the above only is preferred embodiment of the present invention, and is in order to restriction the present invention, within the spirit and principles in the present invention not all, any modification of being done, is equal to replacement, improvement etc., all should be included within protection scope of the present invention.
