Abstract

The present invention provides a method for automatically managing and organizing database of logical channel numbers (LCNs) related to radio-television services, a radio-television apparatus, a remote control device, and a system. The method of the present invention allows a plurality of radio-television services to be hierarchically classified in at least two levels, wherein a first level identifies a broadcaster, and a second level identifies a radio-television service including the selected broadcaster.

Description

TECHNICAL FIELD [0001] The present invention relates to an improved method for automatically managing and organizing a database of LCN (LOGICAL CHANNEL NUMBERS) associated with radio-television, and associated radio-television devices, remote control devices, and systems. LOGICAL CHANNEL NUMBERS RELATED TO RADIO-TELEVISION SERVICES, AND ASSOCIATED RADIO-TELEVISION APPARATUS, REMOTE CONTROL DEVICE AND SYSTEM}

The present invention relates to methods, devices and systems for navigating through radio-television services, in particular radio-television services provided via digital terrestrial broadcasting.

In order to make it easier for users to search for preferred radio-television channels, since most of the radio-television signal receivers have been tuned to receive radio-television programs automatically and stored thereafter There is always a system for; This system is not classified according to the channel frequency during the receiver configuration stage, but for example, 1 for RAI 1, 2 for RAI 2, 3 for RAI 3, and 3 for RETE 4 4 ", " CANALE 5 ", " 5 ", and the like, by associating the name and number of the program broadcaster. Additionally, it was almost always possible for the user to manually re-organize the automatically generated channel list according to his or her own individual criteria.

In digital radio-television signal receivers, the preferred television channel is retrieved by using a number based system referred to as an LCN ("Logic Channel Number") (e.g., LCN = 1 corresponds to "RAI 1" LCN = 2 corresponds to "RAI 2 ").

It is important to specify that the term "channel" should not be used in a digital television to indicate that it should be referred to more as "radio-television service" or more generally "service ". In fact, a channel is a band portion assigned to a service in an analog television, while such a band portion in a digital television includes one or more radio-television services included in a radio-television multiplex, also referred to as a MUX .

The LCN is not intended to identify channels (despite their names), but rather to identify the radio-broadcast channels transmitted by various broadcasters of digital terrestrial television, since they want to use precise terminology, unlike the terms currently in use among the public. Which is a numeric code identifying television services, which, during the configuration stage, is used by most radio stations to automatically assign predefined positions within the classified sequence of radio-television services that the receiver can tune to each of the received services - Used by television receivers should be mentioned. This position is independent of the frequency of the multiplex and broadcast sources to which the service is assigned. For example, "RAI 1" is a radio-television service of a broadcaster or service provider RAI, to which LCN 1 is assigned. To mention just a few, the most important radio-television service providers in Italy are RAI, Mediaset and Telecom Italia Media; In Germany they are ARD, ZDF and RTL; In the US they are ABC, NBC, FOX, FX, "The CW" and PBS.

Also, for clarity, the term "program" refers to single television content (e.g., news) rather than a service (e.g., "RAI 1"). However, the word "program" is also used in place of "service" as a slang word (such as the word "channel"). Some programs, such as news, are made up of just one event, but there are many programs that can be defined as "constainers " and that contain different events (e.g., programs called" Domenica in " . Thus, the broadcaster provides a plurality of radio-television services, and the radio-television service includes a plurality of programs, which in turn include one or more events.

It is also appropriate to recall the definition of a radio-television "bouquet ". This is a set of all radio-television services provided by one broadcaster. In the following description, the terms "bouquet" and "broadcaster" will be used as synonyms.

In a radio-television multiplex, different tables are currently being transmitted, including information about radio frequency (RF) channels, services contained therein, and events of each service. The base tables are defined by an MPEG ("video expert group") organization referred to as PSI ("Program Service Information"), while DVB ("Digital Video Broadcasting" Adds additional tables with tables and event lists. The set of MPEG and DVB tables is referred to as SI ("service information"). For example, a list of radio-television services included in a radio-television multiplex is included in an MPEG table named NIT ("Network Information Table"). However, since the list only includes the code assigned to each service, rather than the full name of each service, the DVB contains the full name of the various services and the radio-television device is able to display the service list And adds the necessary SDT ("Service Descriptor Table").

SI standards are included in the ETSI-EN-300468 document, but the standard application guidelines are included in the ETSI-ETR-101211 document.

Both MPEG and DVB do not implement LCN numbering, which is transmitted in the NIT table by using the so-called "user-defined" descriptor. Such descriptors are specified by the EACEM ("European Association of Consumer Electronics Manufacturers").

Thus, the organization of the SI / PSI tables appears to be somewhat complicated and certainly not properly optimized; Clearly, this is due to the fact that such tables were not conceived as a set by a single standardization body.

With respect to operations for configuring a radio-television device, the latter typically generates a service list categorized according to LCN numbers and presents such list to the users on the screen, It will be free to accept or change.

Once configured, once the user repeatedly presses the next program key "P +" or the previous program key "P-" on the remote control, the device sequentially I will tune to the previous program. For example, in Italy, if the key "P +" is pressed repeatedly, starting from the service with LCN = 1, the device will transmit services "RAI 1 "," RAI 2 ", "RAI 3 "," "Canale 5", "Italia 1", "La 7", "MTV" and so on.

Nevertheless, the user may want to sequentially display all the services provided by the same broadcaster, e.g. RAI. In Italy, however, such services are located in four different radio-television multiplexes, and services other than the three major services "RAI 1", "RAI 2" and "RAI 3" are numerically contiguous 0.0 > LCN < / RTI >

Referring to Figure 1, a first table is shown showing both the RF channels to which the various radio-television multiplexes are transmitted and the respective LCN numbers for the service provider RAI in Italy.

That is, taking the case of Italy as an example, broadcasters, including Mediaset and Telecom Italia Media, in addition to the most important broadcasters, RAIs, can be classified into a service list classified according to LCN numbering in a non- Broadcasts a group of radio-television services stored in the radio-television device. Thus, it is difficult and time consuming for a user to search for radio-television services provided by a particular broadcaster.

To meet this requirement, the DVB organization has identified a table named BAT ("bouquet association table"). However, at least in Italy, the BAT table is not currently transmitted by any broadcaster. As a result, the manufacturers of radio-television receivers are able to "bouquet" across available services in addition to or as a replacement for (based on possibly corrected by the user) Based "navigation. ≪ / RTI >

To facilitate searching for services belonging to its bouquet, the RAI uses an MHP ("Multimedia Home Platform") application, referred to as "Telecomando RAI", which allows all radio-television services To let the user know which program is currently being broadcast, and what to follow.

This application also allows the user to easily tune to all RAI services, even services with an LCN number (e.g., "RAI news 24" with current LCN = 48) .

Unfortunately, the MHP standard is actually only used in Italy, and not all radio-television devices support it. Therefore, users who own a television set that does not support the MHP standard will not be able to use these applications.

In fact, an MHP application named "Telecomando RAI "

- the user has a television set or set-top box with an MHP platform;

- Requires the broadcaster to send a specific MHP application.

In addition, other Italian broadcasters who also have a bouquet of their own services do not use applications similar to those provided by RAI.

Another problem posed by general LCN management is that there may be a plurality of stations with the same LCN, as follows: In such a case, the receiver will tell the user which station he wants the user to store in the location corresponding to that LCN, and whether to move the other stations to the bottom of the list.

This is the case for users receiving television signals from different regions. For example, the local program "RAI 3" can be received near local boundaries as both "RAI 3 " Piedmont and" RAI 3 " Lombardi, all assigned the same LCN = Thus, if the receiver scans the RF band during the initial setup process (or updates the program list), the receiver will find a conflict in the positions assigned to the table of radio-television services, At the bottom of the list, where it is assigned a new LCN by the receiver itself, thereby making it difficult for the user to search for one of the two services.

It is an object of the present invention to provide a method, a radio-television apparatus, a remote control device and a system for automatically managing and organizing a database of LCNs associated with radio-television services, which is an alternative to the conventional ones, And solves the above-mentioned problems of the prior art.

In particular, the present invention automatically provides a database of LCNs associated with radio-television services that allows a user to easily select and view a list of services that belong to the same broadcaster or even belong to the same radio-television multiplex A radio-television apparatus, a remote control device, and a system for managing and organizing a radio-controlled television.

In summary, the following will describe a method, a radio-television device, a remote control device and a system for automatically managing and organizing a database of LCNs associated with radio-television services, wherein a gradual selection by the remote control device In addition to information about the sequence as to which radio-television services should be classified in the list, it is envisaged to transmit an LCN format that also includes information about the broadcaster. This latter information allows the user to browse sequentially the radio-television services belonging to one particular broadcaster or bouquet, even if the associated BAT table has not been transmitted.

Additional features of the invention are set forth in the appended claims, which are intended to be an integral part of this description.

The above objects are achieved by a method for automatically managing and organizing a database of LCNs associated with radio-television services according to the present invention, a detailed description of a radio-television device, a remote control device and a system, It will become clearer when considering.

- Figure 2 shows a system according to the invention.
Figure 3 shows a schematic representation of the remote control device and the radio-television device of Figure 2;
- Figure 4 shows an embodiment of an actuation means of a remote control device according to the invention.
Figure 5 shows a block diagram of the steps of the method according to the invention.

The following describes and exemplifies several preferred embodiments of the present invention with reference to the drawings. Described herein is an embodiment of the present invention that can be used with other features of the present invention without departing from the scope of protection of the present invention as described in the appended claims (e.g., in parts having shapes, dimensions, arrangements, It will be readily apparent that numerous modifications and variations may be applied.

2, there is shown a schematic diagram of a system 1 according to the invention, which system comprises at least one radio-television device 9 (here shown as a television set but, of course, a set- , A video recorder, a decoder, etc.) (which may be any other device suitable for this purpose).

3, a general block diagram of the main components of the system 1 of FIG. 2 according to the present invention is shown. Firstly it comprises a remote control device 2 and the remote control device comprises at least one first central processing unit (CPU) 3 operatively connected to the actuating means 5 and to the transmitting means 7 And the transmitting means may be arranged to transmit control signals, which are activated by the operating means 5 and processed and prepared by the central processing unit 3 for transmission, to the at least one radio-television apparatus 9 Is adapted. The central processing unit 3 is also connected to at least one first memory 11 containing data necessary for normal operation of the remote control device 2. [

It should be noted that the actuating means 5 consists of one or more keys or other switching elements (wheel or mouse) of the remote control device 2 hereby allowing the user to select the radio- .

The lower part of Figure 3 shows the components of the radio-television device 9 used by the invention, namely (a) receiving means 16 adapted to receive control signals transmitted by the remote control device 2 At least one second central processing unit (CPU) 14 operatively connected to the first central processing unit (CPU) 14; (b) a second central processing unit 14, operatively connected to the second central processing unit 14, that includes data necessary to implement the method of the present invention (e.g., LCN database 20, A general block diagram of the memory 18 is illustrated.

In the following description of a preferred but non-limiting embodiment of the present invention, reference to system 1 comprising remote control 2 operatively connected to television set 9, as shown in Figure 3, Anything derived from such a description will be made without any restrictions.

As described above, the information about the LCN corresponding to each service of the multiplex is transmitted by using a descriptor not specified by any of the user-defined descriptors, MPEG or DVB. This descriptor resides in the NIT ("network information table") as a "loop ", where all LCNs of the services included in the multiplex are listed. These descriptors are included in the configuration of all recent radio-television devices, and devices use descriptors to classify services after scanning the entire television band, and the descriptor is a backward word with existing television sets backward compatibility to ensure compatibility.

According to the present invention, the second user-defined descriptor is preferably transmitted in an NIT table, and the NIT table includes another loop with a new type of LCN. This provides an LCN system with two or more levels, where the first level identifies the broadcaster, the second level identifies the radio-television service belonging to the broadcaster, and the third The level identifies the location or location where the service is to be sent.

It is possible to create an LCN database 20 (to be stored in the receiver 9) having two or more levels, access various levels through the control signal transmitted specifically for that purpose, 9), and finally, the steps of selecting the preferred channel for final viewing are present in the system 1 (receiver 9 or remote control 2) according to the present invention Which may be easily managed through appropriate software, which may be generated without difficulty by one of ordinary skill in the art, and will not be further described herein.

In the case of two-level LCNs, two solutions are possible as long as the second level is concerned.

- Radio-television services are numbered in ascending order (for example, "RAI 1") by using a numbering which always starts with a first initial numeric value, e.g. 1, for each broadcaster and has no discontinuity, RAI2 "= 2," RAI3 "= 3," RAI4 "= 4," RAI5 "= 5 and also" Rete4 "= 1," Canale5 "= 2," Italia1 "= 3 Etc.);

- RAI 1 = 1, RAI 2 = 2, RAI 3 = 3, RAI 4 = 21, and RAI 5 = keep the numbering currently in effect (e.g., 23, and also "Rete4" = 4, "Canale5" = 5, "Italia1" = 6, etc.).

The first solution is desirable because users are unlikely to remember LCNs associated with secondary services (e.g., "RAI 4" and "RAI 5"), It is advantageous for those users who do not want to destroy the numbering.

According to a first solution, the new LCN comprises at least two numbers, where the first number identifies the broadcaster, the second number identifies the service, and the services to be transmitted by the broadcaster designated by the first number Is transmitted in a new loop, which is preferably input to the NIT table. The third number will constitute a third level indicating the geographical area.

When the second solution is adopted, the second level of the new LCN will match the conventional LCN already entered in the NIT table via known user-defined descriptors. Thus, the new user-defined descriptor may also include a first-level indication, i. E. Broadcaster only, and possibly a third-level indication (geographical area). Of course, nothing will prevent repeating the second level (service identification) in the new loop, and new television receivers in the new service access mode will have the advantage that they will only have to read the new LCN that will contain all the information And there is no need to read the old LCN representing the second level in the new service access mode. In any case, old television receivers will continue to use the old LCN and ignore the new descriptors.

Referring to Fig. 4, a preferred example of the operating means 5 of the remote control device 2 according to the invention is shown. In this case, the actuating means 5 comprise four keys arranged in a crossing pattern, two of which (B + and B-keys in Figure 4) have access to the first level of LCN numbering, And the other two (S + and S- keys in FIG. 4) allow access to the second level, i. E., Selection of radio-television services from those belonging to the selected broadcaster. If the user repeatedly presses the B + or B- key, the radio-television device 9 will each time tune to a first service (service with the lowest second-level LCN) belonging to the selected broadcaster. If the user repeatedly presses S + and S-, the radio-television device 9 will tune cyclically to the radio-television services belonging to the selected broadcaster.

Thus, the method according to the invention expects that the selection of the desired radio-television service will occur via four keys arranged in a cross pattern, where the first two keys (B +, B-) select the broadcaster Level LCN for selecting a desired radio-television service belonging to the selected broadcaster, and the second two keys (S +, S-) are associated with a second-level LCN for selecting a desired radio-television service belonging to the selected broadcaster.

It is clear that many of the configurations and variations relating to the selection of the keys for selection of the desired radio-television service and their operation in accordance with the present invention may be conceived and obtained. As described above, the method according to the present invention expects the addition of a third level LCN numbering to take into account the cases of radio-television services diversified by local or geographical area. According to what has been mentioned so far, in order to tune to the "RAI 3" Piedmont, the user selects the first level 1 of RAI, then selects the second level 3 of "RAI 3 & "You will have to choose the third level 1 of Piedmont. All of these steps can be performed by means of the remote control device 2 according to the invention. In particular, the choice of broadcaster and service may be done by four keys arranged in a cross pattern, but the choice of locally diversified services, i.e. local services, is particularly important for the next program "PROG +" and / Can be done by using the third two keys which are those associated with the program "PROG- ".

Up to now, it has been assumed that the remote control device 2 is a conventional remote control. However, in general, the remote control device 2 may be a smart phone, a tablet, a remote controller with an alphanumeric keyboard, and the like. In these cases, a modification of the present invention allows the adoption of multi-level LCN numbering with alphanumeric fields. For example, at the first level, the broadcaster RAI may be defined by the letter R or by the full name RAI, and the Mediaset may be defined by the letter M or by the full name Mediaset. Similarly, at the third level, the service "RAI 3 Piedmont" may be indicated by its full name or by the abbreviated name "RAI 3 P " or" RAI 3 Pie ".

This variant provides the advantage of facilitating assimilation by users of LCN numbering according to the invention, from the viewpoint of mnemonic. Such a modification may be employed if the remote control device 2 is a smart phone or tablet, or a remote control with an alphanumeric keyboard or other device capable of providing an alphanumeric keyboard (as virtual via a physical or secondary screen).

In another variant, a menu dedicated to the selection of the desired radio-television service is displayed on the screen associated with the radio-television device 9. [ In this variant, the radio-television device 9 generates and allows the visualization of one or more tables with a list of available radio-television services, which are then transmitted to the remote control device 2 Screen pointer, which is managed and controlled by the user. In this variant, preferably, the radio-television device 9 generates and allows on-screen visualization of a first table with a broadcaster list (the first level of the LCN database 20 according to the invention); Once the broadcaster has been selected (via the remote control device 2), possibly, the radio-television device 9 selects the services belonging to the broadcaster (the second level of the LCN database 20) Screen visualization of the second table for the first table for the first level, and finally, if there is a third level, the radio-television device 9 is locally diversified, i. E. 3 Create and allow on-screen visualization of the table. Such a modification may also function properly in the presence of alphanumeric fields within the LCN numbering according to the present invention.

5, an improved method for automatically managing and organizing the database 20 of LCNs associated with selectable radio-television services for viewing by a user,

- providing (S1) the LCN database 20 consisting of at least two levels of LCN records, i.e., first level LCN records and second level LCN records, Grouped into groups belonging to each one of the first-level LCN records;

- allocating (S2) a first numeric identification type to each radio-television service as a first-level LCN stored in said database (20);

- possibly assigning a second numeric identification type to the radio-television service as a second-level LCN linked to an already assigned first-level LCN,

Selecting (S4) each radio-television service for viewing, starting from its own first-level LCN; And

- if the first-level LCN is the same for more than one service, provide the user with the possibility to select (S5) the desired service for viewing by using the associated second-level LCN, The LCN records identify the broadcaster and the second level LCN records identify the radio-television service belonging to the broadcaster.

Thus, in the case of two-level LCNs, a typical radio-television service is univocally identified by a pair of first-level and second-level LCN record fields; For example, the service "RAI 5" may have an LCN according to the present invention which is the same as "1.5"

Additionally, the method according to the present invention may be arranged such that the radio-television service is expected to be assigned a third numeric identifier type as a third-level LCN linked to a second-

Selecting (S4) each radio-television service for viewing, starting from its own first-level LCN; And

If the first-level LCN is the same for more than one service, selecting a desired service for viewing by using the associated second-level LCN (S5);

If the second-level LCN is the same for more than one service, the user is provided with the possibility to select (S6) the desired service for viewing by using the associated third-level LCN.

As already noted, the third-level LCN identifies locally diversified services, i.e., local radio-television services.

Thus, in the case of three-level LCNs, a typical radio-television service includes three LCN record fields: a first-level LCN record field, a second-level LCN record field, For example, the service "RAI3 TGR Lombardy" may be identified as "1.3.2" or "R" if the RAI3 TGR Piemonte is assigned the same LCN as "1.3.1" or "R.3.1" ≪ / RTI > 3.2 ".

The method also expects that one or more LCN record levels employ LCN numbering with alphanumeric fields.

Thus, the system 1 described above is adapted to implement a method for automatically managing and organizing the following LCN database 20:

- the second memory (18) comprises an LCN database (20) having at least two record levels;

- each service is assigned a first number identification type as a first-level LCN stored in the database (20);

- each service is assigned a second numeric identification type as a second-level LCN linked to an already assigned first-level LCN;

- if the number of levels is greater than 2, each service is assigned a third numeric identification type as a third-level LCN linked to a previously assigned second-level LCN;

- a second central processing unit (14), which, upon input from the actuation means (5), starts each of its services for viewing, starting from its own first-level LCN as entered via the actuation means Adapted to select;

If the first-level LCN is the same for more than one service, the second central processing unit 14, upon input from the actuating means 5, Adapted to select a desired service for viewing by using a level LCN;

If the number of LCN levels is greater than 2 and the second-level LCN is equal for more than one service, the second central processing unit 14, upon input from the actuating means 5, Adapted to select the desired service for viewing by using the associated third-level LCN as entered via < RTI ID = 0.0 >

Also, the values of the first-level and second-level LCNs may be transmitted to the radio-television device 9 by the broadcaster. The same applies to the third-level LCN. Particularly preferably, the broadcaster information on the first LCN level, the information on the second LCN level, and the information on the third LCN level are stored in a user-defined Lt; / RTI >

The method according to the present invention may be implemented by a computer program product that may be loaded into the memory 18 of the device 9, which includes portions of software code adapted to implement the method.

The advantages of the present invention as well as the features of the present invention will be apparent from the above description.

The first advantage of the method, the radio-television device, the remote control device and the system according to the invention is that the user first selects the preferred television broadcaster (e.g. RAI, Mediaset, LA7) It is possible to select a desired radio-television service from those available from that broadcaster. A second advantage of the method, the radio-television device, the remote control device and the system according to the present invention is that collisions between LCNs (services with the same LCN) are avoided and that services need to be retrieved at the bottom of the list And can be readily selected by their unique LCN without having to do so.

The associated radio-television apparatus, remote control device and system as well as a method for automatically managing and organizing a database of LCNs related to radio-television services are capable of many possible changes without departing from the novel idea of the invention It is also apparent that in the practicable implementations of the present invention, the illustrated details may have different shapes or may be replaced by other elements that are technically equivalent.

Accordingly, the present invention is not limited to the associated radio-television device, remote control device and system, as well as to a method for automatically managing and organizing a database of LCNs related to radio-television services, It will be readily appreciated that many modifications, enhancements, or equivalents may be resorted to without departing from the spirit of the invention as set forth in the following claims.
