Abstract
A method, a television broadcasting unit, a remote control device and a system for automatically managing and organizing the database of the LCN (Logical Channel Number) in the context of television broadcasting services are described; the method allows to obtain a hierarchical classification on at least two levels of several television broadcasting services, a first level the broadcaster and a second level identifies the television broadcasting service, which is part of the selected broadcaster.
Description
Technical field
The present invention relates to the methods, devices and systems navigating through radio and television services, particularly relate to the methods, devices and systems that the radio and television services provided via DTB Digital Terrestrial Broadcasting are provided.
Background technology
Known, in order to make the broadcast TV channel of user's searching preferences easier, since the epoch of simulated television, most of broadcast television signal receiver is always equipped for automatically tuning to receivable broadcast TV program and storing the system of these broadcast TV programs; During receiver configuration phase, this system produces the list of receivable channel, this list is sorted by the name of numeral and program broadcaster being associated, such as 1 for " RAI1 ", 2 for " RAI2 ", and 3 for " RAI3 ", and 4 for " RETE4 ", 5 for " CANALE5 " etc., contrasts with sorting according to channel frequency.In addition, user manually to reorganize according to the individual standard of his/her the channel list automatically produced almost always possible.
In digital broadcasting-television signal receiver, the television channel by using the system based on the numeral being called LCN (" logical channel numbers ") to carry out searching preferences: such as, LCN=1 corresponds to " RAI1 ", and LCN=2 corresponds to " RAI2 " etc.
Importantly, prescribed term " channel " is not taken in Digital Television the thing being used to refer to and should being more suitable for being called " radio and television services " or being more generally called " service ".In fact, channel is the band part being assigned to service in simulated television, and in Digital Television, this band part comprises the one or more radio and television services be included in radio and television multiplexed (also referred to as MUX).
Want to use correct term, contrast with the term of use current in the common people, what must say is, LCN is nonrecognition channel (to the greatest extent let it be name) but identifies the digital code of the radio and television services transmitted by the various broadcasters of digital terrestrial television, this digital code is used automatically to be assigned to each service by most of broadcast television receiver during configuration phase, these service receiver can be tuned to radio and television services collating sequence in receive predefined position.This position is independent of serving the multiplexed frequency that has been assigned to and independent of broadcast source.Such as, " RAI1 " is the radio and television services of broadcaster or ISP RAI, and LCN1 is assigned to it.Only mention, in Italy, most important radio and television services supplier is RAI, Mediaset and TelecomItaliaMedia; In Germany, they are ARD, ZDF and RTL; In the U.S., they are ABC, NBC, FOX, FX, " TheCW " and PBS.
And for clarity sake, term " program " refers to single television content (such as news), instead of refer to serve (such as " RAI1 ").But in popular language, word " program " (just as word " channel ") is also used for replacing " service ".Some programs (such as news) comprise an only event; But exist and can be defined as " container " and the many programs comprising different event, such as, be called the program of " Domenicain ".Therefore, broadcaster provides multiple radio and television services, and radio and television services comprise multiple program, and program comprises again one or more event.
The definition reminding radio and television " collection (bouquet) " is also suitable.This is the set of all radio and television services provided by a broadcaster.In the following description, term " collection " and " broadcaster " will as synonyms.
Different forms is current in the multiplexed middle transmission of radio and television, and it comprises about RF (broadcasting frequency) channel, the information being included in the event of service in RF channel and each service.Basic form is defined by MPEG (" Motion Picture Experts Group ") tissue, be called PSI (" Program Service Information "), simultaneously DVB (" digital video broadcasting ") tissue add comprise about the more details of serving other forms and there is the further form of list of thing.The set of MPEG and DVB form is called SI (" information on services ").Such as, be included in radio and television multiplexed in the list of radio and television services be included in the mpeg table lattice being called NIT (" network information table ").But, because this list only comprises the code being assigned to each service, and does not have its full name, DVB adds SDT (" service descriptor table "), it states the full name of various service, and this is required for the broadcast television apparatus that can show service list.
SI specification is included in ETSI-EN-300468 document, and Regular application guide is included in ETSI-ETR-101211 document.
MPEG and DVB does not realize LCN numbering: it is transmitted by so-called " user-defined " descriptor of use in NIT form.This descriptor is specified by EACEM (" European consumer electronics makers association ").
Therefore, the organize results of SI/PSI form is quite complicated and does not certainly suitably optimize: this is obviously because this form is not also contemplated that the fact gathered by single standardization body.
About the operation of configuration broadcast television equipment, broadcast television apparatus typically produces the service list according to LCN numeric sorting, and this list is presented on to user on screen, and user then will freely or accept it or desirably change it.
Once configuration terminates, if user repeatedly presses next program key " P+ " or previous program key " P-" in remote control, device by according to the order that defined by LCN, sequentially respectively be tuned to next or previous program.In Italy, such as, if repeatedly pressing key " P+ " from the service of LCN=1, device will sequentially be tuned to service " RAI1 ", " RAI2 ", " RAI3 ", " Rete4 ", " Canale5 ", " Italia1 ", " La7 ", " MTV " etc.
But user may want sequentially to show all services provided by same broadcaster (such as RAI).But, in Italy, this service be placed in four different radio and television multiplexed in, and except main three services " RAI1 ", " RAI2 " and " RAI3 ", other serve with numerically and discontinuous LCN value be associated.
With reference to figure 1, show first form transmitting the multiplexed RF channel of various radio and television and corresponding LCN numeral wherein of the gondola ISP RAI of instruction.
In other words, with gondola situation as an example, most important broadcaster is (namely except RAI, also comprise Mediaset and TelecomItaliaMedia) broadcast one group of radio and television services, these radio and television services are stored in broadcast television apparatus according to numbering according to the LCN of discontinuous mode the service list stored.Therefore, the radio and television services that user search is provided by specific broadcaster be difficulty and consuming time.
In order to meet this demand, DVB organization prescribed is called the form of BAT (" collection contingency table ").But at least in Italy, BAT form is current not to be transmitted by any broadcaster.Result, the manufacturer of broadcast television receiver does not also realize any measure, what allow " based on collection " navigates through obtainable service, as adding or substituting the navigation based on the service list sorted according to LCN logic (may be corrected by user).
The service of the collection of RAI is belonged to for the ease of search, RAI uses MHP (" multimedia home platform ") application---is called " TelecomandoRAI ", it is for all radio and television services belonging to supplier RAI, allow user know current broadcasting which program and subsequent which will be.
This application also allow user easily be tuned to all RAI service, even have the LCN numeral that user typically do not remember those (such as " RAI news 24 ", current there is LCN=48).
Unfortunately, MHP standard is only in the actual use of Italy, and not every broadcast television apparatus all supports it.Therefore, have and do not support that the user of the television set of MHP standard can not use this application.
In fact, the MHP application being called " TelecomandoRAI " requires:
-user has the television set or Set Top Box with MHP platform;
-broadcaster sends specific MHP and applies.
And other Italian broadcasters equally with they self services set do not use the similar application provided with RAI.
Another problem proposed is managed as follows: there are multiple with identical LCN may occur by normal LCN; In this case, by inquiry user, which platform he/her wants be stored in the position corresponding with this LCN to receiver, and other is moved to bottom list.
This is the situation that user receives the TV signal from zones of different." RAI3 " (being such as regional program) (such as between Piedmont and Lombardy) near zone boundary can not only be received as " RAI3 " Piemonte but also as " RAI3 " Lombardia, and they have been designated identical LCN=3.Therefore, when receiver scans RF wave band during initial setup process (or when upgrading the rendition list), it will find the conflict of the position of specifying in radio and television services form, and by the two, any one is placed on bottom list, specify new LCN by receiver self to it, thus make user be difficult to search two service described one.
Summary of the invention
An object of the present invention is a kind of method by providing automatic management and the database of the tissue LCN relevant to radio and television services, broadcast television apparatus, remote control equipment and system (alternative as to traditional those), solving the problems referred to above of prior art.
Particularly, the method of the database of the LCN that the object of the invention is to provide a kind of automatic management relevant to radio and television services with tissue, broadcast television apparatus, remote control equipment and system, they make user easily select in order and watch the list belonging to same broadcaster or even belong to the multiplexed service of same radio and television.
In brief, below by the method for the database of LCN relevant to radio and television services with tissue for a kind of automatic management of description, broadcast television apparatus, remote control equipment and system, wherein imagination transmission LCN form, except the information of the order progressively selected except sorting in lists according to it about radio and television services so that by remote control equipment, also comprise the information about broadcaster.This latter information allows user sequentially to browse to belong to the radio and television services of a specific broadcaster or collection, even without the BAT form that transmission is relevant.

Embodiment
With reference to accompanying drawing, will describe below and example preferred embodiments more of the present invention.By becoming distinct be immediately; as described hereinly may experience numerous modifications and amendment (such as; shape, size, arrange and there is identical functions parts in), and do not deviate from the protection scope of the present invention stated in claims.
With reference to figure 2, show the schematic diagram according to system 1 of the present invention, it comprises and operation is connected at least one broadcast television apparatus 9 (is shown as television set here, but certainly can be any other equipment being suitable for this object, such as Set Top Box, video tape recorder, decoder etc.) remote control equipment 2 (being shown as common remote control here).
With reference to figure 3, show the general frame of the primary clustering of the system 1 according to Fig. 2 of the present invention.First, it comprises remote control equipment 2, it can advantageously comprise: at least one first CPU (CPU) 3, its operation is connected to actuated components 5 and transmission part 7, and transmission part 7 is suitable for be driven by actuated components 5 and is processed by CPU 3 and the control signal preparing to be used for transmitting is transferred to this at least one broadcast television apparatus 9.CPU 3 is also connected at least one first memory 11, and it comprises the necessary data of normal running of remote control equipment 2.
It should be noted that actuated components 5 is made up of one or more key of remote control equipment 2 or another kind of switching device (wheel or mouse) here, user can select radio and television services to watch by them.
The bottom of Fig. 3 illustrates the general frame of the assembly of the broadcast television apparatus 9 used by the present invention, namely: (a) at least one second CPU (CPU) 14, operation is connected to receiving-member 16, receiving-member 16 is suitable for receiving the control signal transmitted by remote control equipment 2; B () at least one second memory 18, operation is connected to the second CPU 14 and comprises and realize the necessary data of method of the present invention (such as LCN database 20, it will describe subsequently).
To in the following describes of preferred but nonrestrictive embodiment of the present invention, with reference to the system 1 be made up of the remote control 2 that operation is connected to television set 9, as shown in Figure 3, but in any case from these describe, do not derive any restriction.
As previously described, about the information of the LCN answered with multiplexed each service relative by using user-defined descriptor---the descriptor namely not yet specified by MPEG or DVB transmits.This descriptor is present in NIT (" network information table ") as " ring (loop) ", wherein list be included in multiplexed in all LCN of service.This descriptor is included in all broadcast television apparatus of structure in the recent period, and broadcast television apparatus utilizes its sequence service after the whole TV wave band of scanning, and it needs not make an amendment ground transmission continuously, to ensure the back compatible with existing television set.
According to the present invention, user-defined second descriptor is transmitted, and preferably in NIT form, it comprises another ring with newtype LCN.This provides the LCN system with two or more ranks, wherein first level identification broadcaster, and second level identification belongs to the radio and television services of described broadcaster, and possible third level identification service transmission from region or place.
Establishment has the LCN database 20 (by being stored in receiver 9) of two or more ranks and the control signal sent especially by the object for accessing various rank visits various rank, and on the screen of receiver 9, show the channel list of expectation, and the last step selecting the channel of preference finally to watch is the step that the suitable software (in receiver 9 or in remote control 2) by existing in system 1 according to the present invention can easily manage, it can not here further describe, because it can be created like a dream by those skilled in the art.
When two-stage LCN, consider second level, two kinds of solutions are possible:
-by using a kind of numbering, radio and television services are numbered with ascending order, and this kind of numbering always starts with the first initial value such as 1 for each broadcaster, and does not interrupt (such as, " RAI1 "=1, " RAI2 "=2, " RAI3 "=3, " RAI4 "=4, " RAI5 "=5, and same " Rete4 "=1, " Canale5 "=2, " Italia1 "=3 etc.);
-radio and television services keep current effective numbering (such as, " RAI1 "=1, " RAI2 "=2, " RAI3 "=3, " RAI4 "=21, " RAI5 "=23, " Rete4 "=4, " Canale5 "=5, " Italia1 "=6 etc.).
First solution is preferred, because user will remember that (LCN that such as " RAI4 " is relevant with " RAI5 " is unlikely, and the second solution is familiar with for having become current LCN numbering and does not want that those users abandoning it are favourable to secondary service.
According to the first solution, (wherein first digit identification broadcaster and second digit identification are served for the new LCN that is made up of at least two numerals, serve from specified by first digit broadcaster transmission those select) transmit in new ring, it preferably inputs in NIT form.Third digit will form third level, instruction geographic area.
If adopt the second solution, the second level of new LCN is by overlapping with the traditional LC N inputted in NIT form by known user-defined descriptor.Therefore, new user-defined descriptor only may comprise first level instruction (namely broadcaster), and also may comprise third level instruction (geographic area).Certainly, do not have anything to stop in new ring, repeat second level (service identifies), its advantage is that the new television receiver under new service access pattern only will must read new LCN (it will comprise all information), and not needing the same old LCN that reads, old LCN represents second level in new service access pattern.In either case, old television receiver will still use old LCN, ignores new descriptor.
With reference to figure 4, show the preferred embodiment of the actuated components 5 according to remote control equipment 2 of the present invention.In this case, actuated components 5 comprises four keys arranged with cross figure, wherein two allow the first level of access LCN numbering, namely broadcaster selects (B+ and the B-key in Fig. 4), and two other (S+ and S-key in Fig. 4) allows access second level, is namely subordinated in the radio and television services of selected broadcaster and selects radio and television services.If user repeatedly presses B+ or B-key, so broadcast television apparatus 9 by each be tuned to belong to first service (there is of minimum second level LCN) of selected broadcaster.If user repeatedly presses S+ and S-key, so broadcast television apparatus 9 by cyclically be tuned to belong to the radio and television services of selected broadcaster.
Therefore, the selection of the radio and television services that method imagination according to the present invention is expected is occurred by four keys arranged with cross figure, wherein one or two key (B+, B-) with for selecting the first level LCN of broadcaster to be associated, the second two keys (S+, S-) are associated with the second level LCN of the radio and television services for selecting the expectation of described selected broadcaster.
Obviously, can conceiving and obtain many configurations and modification, is all the selection about key and operation thereof, to select the radio and television services expected according to the present invention.
As previously described, increase the LCN numbering of third level according to method according to the present invention imagination, so as to consider radio and television services because of region or geographic area diversified situation.According to up to the present described, in order to be tuned to " RAI3 " Peimonte, user must select the RAI of first level 1, then select " RAI3 " of second level 3, finally select " RAI3 " Piemonte of third level 1.All these steps can perform by remote control equipment 2 according to the present invention.Especially, the selection of broadcaster and service can be undertaken by four keys arranged with cross figure, and the selection of the diversified service in region (namely regional service) can pass through use the 3 two key---be associated with next program " PROG+ " and/or previous program " PROG-" specifically those---carries out.
Up to the present, supposed that remote control equipment 2 is conventional remote controls.But usually, remote control equipment 2 can be smart mobile phone, flat board, have the remote control etc. of alphanumeric keyboard.In these cases, a kind of variant of the present invention allows to adopt the multi-level LCN numbering with alphanumeric field.Such as, in first level, broadcaster RAI can define by letter r or by full name RAI, and Mediaset can define by alphabetical M or by full name Mediaset.Similarly, in third level, service " RAI3Piemonte " can indicate by its full name or by abbreviated name " RAI3P " or " RAI3Pie ", etc.
From the viewpoint of memory, this variant provides is convenient to the advantage of user to the absorption that LCN according to the present invention numbers.Maybe can provide another equipment of alphanumeric keyboard (physics or virtual alphanumeric keyboard in secondary screen) if remote control equipment 2 is smart mobile phone or remote control that is dull and stereotyped or that have an alphanumeric keyboard, this variant can be adopted.
In another variant, be exclusively used on the screen selecting the menu of radio and television services expected to be presented to be associated with broadcast television apparatus 9.In this variation, broadcast television apparatus 9 produces and to allow one or more forms with obtainable radio and television services list visual, and these forms then can be selected by the pointer (managed by remote control equipment 2 and control) on screen by user.In this variation, broadcast television apparatus 9 preferably produces and allows the onscreen visualization to first form with broadcaster's list (first level according to LCN database 20 of the present invention); Once have selected broadcaster's (by remote control equipment 2), broadcast television apparatus 9 may can produce and allow the onscreen visualization to the second form, to select the service (second level of LCN database 20) belonging to described broadcaster, and it is last, if third level exists, broadcast television apparatus 9 produces and allows the onscreen visualization to the 3rd form with the list that region variation (namely regional) is served.This variant suitably works when even can there is alphanumeric field in LCN numbering according to the present invention.
Generally speaking, with reference to figure 5, comprise step for the improving one's methods of database 20 automatically managed with organize to the LCN that the radio and television services watched can be selected relevant by user:
-provide (S1) to record by the LCN of at least two ranks the LCN database 20 formed, the LCN record of the LCN record of described at least two ranks and the LCN record of first level and second level, second level LCN record is grouped in the group of the corresponding LCN record belonging to first level LCN record;
-specify (S2) first digital identification types to each radio and television services, as the first level LCN be stored in described database 20;
-possibly, specify the second digital identification types to described radio and television services, as the second level LCN being linked to the first level LCN specified;
To be supplied to the following possibility of user:
-by the first level LCN from radio and television services self, select (S4) each radio and television services to watch; And
If-first level LCN is identical for more than one service, then the service by using relevant second level LCN to select (S5) to expect is watched;
Wherein the LCN record of first level identifies broadcaster, and the LCN of second level records the radio and television services identifying and belong to described broadcaster.
Therefore, when two rank LCN, general radio and television services by first level and second level LCN record field to identifying clearly; Such as, serve " RAI5 " and the LCN equaling " 1.5 " or " R.5 " can be had according to the present invention.
In addition, method according to the present invention imagines described radio and television services appointment has the 3rd digital identification types, as the third level LCN being linked to the second level LCN specified;
To be supplied to the following possibility of user:
-by the first level LCN from radio and television services self, select (S4) each radio and television services to watch; And
If-first level LCN is identical for more than one service, then the service by using relevant second level LCN to select (S5) to expect is watched;
If-second level LCN is identical for more than one service, then the service by using relevant third level LCN to select (S6) to expect is watched.
Specify, third level LCN identifies the diversified service in region, namely regional broadcast TV service.
Therefore, when three rank LCN, general radio and television services are identified clearly by three LCN record fields (namely first level, second level and third level); Such as, service " RAI3TGRLombardia " can have the LCN equaling " 1.3.2 " or " R.3.2 " according to the present invention, if RAI3TGRPiemonte specifies the LCN equaling " 1.3.1 " or " R.3.1 ".
And the present invention imagines one or more LCN and records the LCN numbering that rank employing has alphanumeric field.
Therefore said system 1 is suitable for the method realized as follows for automatically managing and organize LCN database 20:
-second memory 18 comprises the LCN database 20 with at least two record ranks;
