"Device, procedure and system to generate audiovisual events"

Technical sector of the invention

The invention relates to a device, method and system that allow generating additional audiovisual events related to a broadcast and offering additional services to users.

Background of the invention

It is known to broadcast broadcast signals to transmit television broadcasts that incorporate data referring to the type of broadcast, so that the receiving devices can show the user information regarding the broadcast broadcast. This information regarding the broadcast program includes the title of the program and even details of the program being broadcast and is defined in digital television broadcasting standards such as Digital Video Broadcasting-Service Information (DVB-SI). To add additional content to an audiovisual signal broadcast, communication standards are known, such as "Multimedia Home Platform" (MHP) that allows digital data to be incorporated into an broadcast so that it is interpreted by the receiving device as additional content to the television broadcast . However, said additional contents have to be added to the broadcasting signal emitted by the television stations together with the audiovisual signal to which only the operator of the television station has access. In addition, the additional contents may not be directly related to the programming that is broadcast, since these are continuously broadcast by the operator of the station.

A solution to add additional content that does not need to incorporate the data of the interactive applications to the signal of Broadcasting is described in the device and procedure of patent document US6240555, based on the modification of the electronic program guide service (EPG). The EPG service allows you to locate a broadcast based on a specific time interval and a specific channel. Patent document US6240555 suggests that said EPG be modified so that the broadcast highlighted in a specific time interval and channel, also includes information on whether said emission is related to additional contents. However, said device has the disadvantage that it requires that the EPG be periodically updated with information on the additional contents of the successive programs, the information on additional contents being lost if the EPG could not be updated and also not allowing the reuse of the EPG entries. . Another drawback is that if there was a sudden change in television programming and the EPG could not be updated in time, said device would not correctly display the information on additional content based on an EPG whose sequence of contents would not correspond to the broadcasting

Devices such as the one described in the US2003028884 patent are also known which allows the user to suggest the visualization of other programs available in the programming, such as those registered in the EPG, based on previously used search criteria, as well as based on information from the contents that the user has previously downloaded. Said procedure also has the disadvantage that if the list of programs available in the programming is not updated, the device may suggest the display of a program that, due to a sudden change in the television programming, is not broadcast.

It is therefore necessary a procedure that allows the incorporation of additional content that adds value to television broadcasts, without having to modify the signal emitted by the broadcasting station and that does not require periodic and constant updating of the devices decoders to adapt to the new programming. In addition, it is convenient that this procedure be robust in the face of sudden programming changes, being able to continue showing additional content even if a television broadcast does not correspond to the one that was previously programmed.

Explanation of the invention

The method according to the invention is one of those used to generate audiovisual events and which comprises the operations of receiving a signal, such as a broadcasting signal, which comprises at least one broadcast that includes a first audiovisual content and data associated with said content. audiovisual; tune in and extract from this broadcast the first audiovisual content and the data associated with it.

In essence, it is characterized in that it also includes the operations of comparing in real time and iteratively at least part of the associated data that is continuously extracted from the broadcast with predefined data stored in storage media; generate an output signal suitable to be transmitted to a first peripheral device comprising the first audiovisual content extracted that, if the result of the comparison meets pre-established requirements, is modified with the addition of a second audiovisual content; transmit the output signal to the first peripheral device to be shown.

In a variant of the invention, the associated data received in one iteration is stored temporarily to be compared with the associated data received in the next iteration, and if these are the same, do not perform the comparison.

In a variant of interest, it also includes the operations of receiving an acceptance order generated by a user through a second peripheral device in response to the sample of the second audiovisual content; obtain additional content, linked to the data associated with the first audiovisual content; and generate automatically an audiovisual event based on such additional content data.

According to another variant of the invention, the additional content data is obtained after the execution of a local application. In accordance with another feature of the invention, the obtaining of additional content data includes access to remote data sources through communication means.

According to another characteristic, the obtaining of additional content data is carried out by means of a point-to-point connection with a service provider.

In another variant of interest, it also includes the establishment of a two-way communication with a data server with additional content.

According to another embodiment of the invention, the predefined data stored in the storage media are remotely updateable.

In another variant of interest, the predefined data stored in the storage media comprises keywords related to the title of the audiovisual content and locators to obtain the additional contents.

According to another aspect of the invention, a device is disclosed for the implementation of the method also object of the invention comprising reception means for receiving a signal, such as a broadcasting signal; tuning and extraction means that allow to extract from said signal an emission with a first audiovisual content and some data associated with said audiovisual content; storage means with predefined data to obtain additional contents; processing means adapted to compare at least part of the data associated with the first audiovisual content extracted with the predefined data stored in the storage media and generate an output signal suitable for transmission to a peripheral device comprising the first audiovisual content extracted and, if the result of the comparison meets pre-established requirements, modified with the addition of a second audiovisual content.

According to another characteristic, the device also includes transducer means, adapted to receive an acceptance signal generated by a second peripheral device and that trigger the obtaining and presentation of additional contents, linked to the data associated with the first audiovisual content.

According to another feature of the invention, the device comprises bidirectional communication means for communicating with a service provider.

In another variant of interest, the media of the device is wireless.

In a variant, the means of communication of the device comprise a telephone modem.

Advantageously, the device therefore allows additional content to be incorporated into a television broadcast without these having to be incorporated into the broadcasting signal at source, or prior to its reception by the device. In accordance with another aspect of the invention, a system comprising at least one device according to the invention is also disclosed and also comprises a broadcasting station that emits at least one signal, such as a broadcasting signal, which incorporates a first content audiovisual and data associated with said audiovisual content; and a service provider to which the device connects.

In another variant of the system, it also comprises at least one additional content server connected to the service provider via a communication network, so that the service provider acts as a gateway between the device and the servers. Brief description of the drawings

Detailed description of the drawings

The following description refers to the drawings presented above, which allow a detailed appreciation of the operation of the present invention. As can be seen in FIG. 1, the device 1 has processing means 2, tuning means 3 and communication means 4. Said tuning means 3 and communication means 4 are formed by modules that They have two processors dedicated to execute the specific tasks for which they are intended. In order to obtain information exchange, these processors are connected to the processing means 2 by means of data buses 5 and control lines 6. Thus, the processing load is distributed among the different components of the device 1 and the processing means are allowed 2 can be dedicated exclusively to execute processes that offer added value to device 1.

The tuning means 3 allows to select in a known way from among the plurality of broadcasting signals 24 received by the receiving means 25 of the device 1, a signal corresponding, for example, to a television broadcast 11 (see Fig. 2) Naturally , in other variants of the invention, the television broadcast 11 can be received through other means known to the state of the art, such as coaxial cable or optical fiber, and television broadcasts of the multicast type are also contemplated, with a single sender and multiple receivers, or unicast, with a sender and a single receiver, such as on-demand television services.

From the selected television broadcast 11, the tuning means 3 are adapted to extract a first audiovisual content 7, which contains the image and sound of said broadcast, and the data associated 8 to said audiovisual content in DVB-SI format, which includes, among others, the title 9 of the audiovisual content, as can be seen in Fig. 2. This information is sent to the processing means 2 via the data bus 5 located between the tuning means 3 and the processing means 2. The communication means 4 comprise a telephone modem 4a which allows communication with a service provider 12, as will be explained later, enabling the device 1 communicate bidirectionally and access the information offered by said service provider 12. In turn, the service provider 12 can act as a gateway to interconnect the device 1 with other servers 13 acting from remote data sources 19, as will be described later.

As can be seen in Fig. 1, the device 1 also has storage means 14, which contain a database 15 with information regarding the first audiovisual contents 7 that have additional content 16 associated. The database 15, represented in Fig. 2, contains keywords 18a that serve to relate the title 9, which is obtained from part of the data associated 8 to the broadcast 11 that are received together with the first audiovisual content 7, with said additional contents 16. In the example of Fig. 2, said additional contents 16 are referenced by locators 18b contained in the database 15 and related to their corresponding keywords 18a. In this way, the database 15 includes predefined pairs of data 17 formed by keywords 18a and locators 18b that will be used to resolve whether a first audiovisual content 7 received has additional contents 16. Said locators 18b also designate the action that should be perform the processing means 2 to generate or obtain the additional contents 16. Fig. 2 shows an example of the content of the database 15 that contains predefined pairs of data 17 that relate keywords 18a to locators 18b. Said locators 18b can imply access to local or remote resources that allow the elaboration or interpretation of additional contents 16. These can be, for example, commands of local applications to be executed, memory addresses, tagging files of HTML or XML tags, interpreted or compiled language files or even information contained in storage media, such as CD or DVD tracks. In Fig. 2 a locator 18b is observed in the form of a URL indicating that the additional content 16 It is described in an HTML file that is located on the "prodi .tv" server. Obviously, if the URL describes the name of the server and not its IP address, it must be previously obtained through a DNS server that must be provided for this purpose in the service provider 12, in one of the accessible servers 13, as It is shown in Fig. 7, or even in the device 1 itself.

In the example of Fig. 2, it is obtained from the data associated with the broadcast 11, the title 9 of the first audiovisual content 7 that is being broadcast, "productol", and this is compared with the keywords 18a. In this case, a match would be found with the keyword "productol", with which the related locator 18b would be obtained, allowing access to the additional contents 16 associated with said locator 18b.

If the additional contents 16 have to be modified, if their corresponding locator 18b is a URL, then to update the additional contents 16 it will only be necessary to update the additional content 16 designated on the server 13 by the URL, without having to modify the affected locators 18b of the database 15, that is, without having to remotely access the device 1. However, if a locator 18b cannot be reused to drive to the new additional contents 16, the affected locators 18b of the database 15 that are part of the predefined data 17 stored in the storage media 14 must be updated. It is also possible to update the database 15 to incorporate new predefined data 17, adding new keywords 18a and their corresponding locators 18b, as well as eliminating those predefined data 17 that are no longer desired to be used.

Said update can be done remotely, the device 1 being able to access a remote server periodically by means of the communication means 4 to verify if there is an updated version of the predefined data 17 and, if it exists, to download said predefined data 17, updating, replacing or eliminating part or Ia all of the predefined data 17 of the database 15. Alternatively, an administrator from a remote device can force the update of the database 15 of one or a plurality of devices 1 by sending a previously predetermined update signal or even sending directly the predefined data 17 to said devices 1. The communications between the administrator and the devices 1 must be secure and the latter must be correctly identified in the devices 1 to avoid being supplanted by malicious users. Naturally, if the use of local resources, stored in storage media 14, is required, they must be equally updatable.

The database 15 has the advantage that although it is not updated, if a first audiovisual content 7 has previously been related to additional content 16, subsequent audiovisual contents whose data associated 8 to the broadcast 11 contain the same title 9 will also be related to the same additional contents 16, being in this case unnecessary to update the database 15, with the consequent saving of processing by avoiding having to update each and every one of the devices 1.

Additionally, even if an audiovisual content is received outside of the initially planned or predetermined programming, it will be unequivocally related to the additional contents 16 related to the first audiovisual content 7. Naturally, the storage means 14 of the device 1 also allow temporary storage, the remote data used to generate the additional content 16, allowing not having to re-download those remote data that have not changed and that have been previously downloaded. However, it will be necessary to ensure that these have not changed by generating future additional content 16.

The storage means 14 also serve to store the operating system of the device 1 and the libraries and applications that will be used by the processing means 2.

The operating system of device 1 is a specialized GNU / Linux optimized for embedded devices, although of course any other properly adapted operating system would be usable.

The applications that the operating system includes are similar to those that can be found in other GNU / Linux distributions, the only limitations for the execution of applications being the common ones in embedded devices, that is to say power of the main processor, available memory and peripherals.

As an example, the applications installed on device 1 are web browser, email application, instant messaging application, etc. Said applications can be accessed by second peripheral devices 20, as shown in Fig. 1 in which said second peripheral devices 20 is a remote control 20 'with dedicated buttons 20a, or by selection menus. It is also possible to directly access them transparently to the user if an application is related to a predetermined channel number, the user directly accessing the application by selecting said predetermined channel through the remote control 20 '. Furthermore, since the device 1 is advantageously provided with the communication means 4, applications that require network access can access it through said means. These can also be used to receive updates of the information contained in the storage means 14, such as updates of the operating system of the device 1 and updates of the predefined data pairs 17.

In this way, the creators of additional contents 16 have the option of depositing them in a remote server 13 and that is accessible by the device 1 through the service provider 12 and updating the database 15 of the device 1 so that it incorporates a pair of predefined data 17 whose keywords 18a are related to the title 9 of the first audiovisual content 7 of interest and whose locator 18b includes the URL of the additional contents 16 deposited on the server 13.

The processing means 2 allow to modify the first audiovisual content 7, allowing the user to be warned of the existence of additional contents 16 related to the first audiovisual content 7 tuned and that is being viewed through the television

10 '.

To verify that the first audiovisual content 7 has additional contents 16, the processing means 2 perform, iteratively, the procedure described in Fig. 3. In a first stage 101 the title 9 of the first audiovisual content 7 is obtained. it is received from the tuning means 3 from the data associated with the broadcast 11. In a second stage 102 it is checked if it has changed with respect to the previous title, obtained in the previous iteration, jumping to the next iteration in case these Be the same However, if these are different or there is no previous title as it is the first iteration, we proceed to the comparison stage 103, in which the title 9 is compared with the list of keywords 18a contained in the database 15 If the title 9 coincides with the keyword 18a of a pair of predefined data 17 of the database 15, it is assumed that there is a locator 18b related to the first audiovisual content 7 received. If a match is found, the result of the comparison stage 103 will be considered positive and, according to a variant of the invention, the activation 105 of a second audiovisual content 21, which can be for example an icon 21a of alert, to warn the user that the first audiovisual content 7 has additional content 16 associated, generating an output signal 23 which also includes the first audiovisual content 7 the second audiovisual content 21 in the form of alert 21a, so that can show on the first peripheral device 10, which in this case is a television 10 ', the image of Fig. 4. In other variants of the invention, the second audiovisual content 21 can also incorporate additional contents 16 such as that shown in Fig. 5, in which the second audiovisual content 21 is a frame 21 b with useful information for the user.

Although in the variants represented the second audiovisual content 21 is eminently visual and intended to be included together with the first audiovisual content 7 in the output signal 23 to be transmitted and displayed through a television 10 ', other second audiovisual contents 21 that allow to capture the user's attention would also be susceptible to being used, such as sound notices, light components or even local warnings in peripheral devices, such as vibrations.

If the comparison stage 103 had a negative result, deactivation 106 of the second audiovisual content 21 would be carried out, containing the output signal 23, therefore, only the first audiovisual content 7. This last case would occur when the Ia broadcasting of a first audiovisual content 7 with additional content 16 and the following audiovisual content no longer had associated additional content 16.

If the second audiovisual content 7 is incorporated into the first audiovisual content 7, the latter will be shown during a predetermined time or during the duration of the first audiovisual content 7, as preselected in the device 1. Between iterations of the procedure described in Ia Fig. 3, we proceed to a waiting stage 107, whose waiting time must be sufficient so that the processing means 2 is not overloaded with too many comparisons and a user tolerable delay is also preserved between showing a new first content audiovisual 7 and the second audiovisual content 21 is activated and deactivated if it presents additional content 16.

In another variant of the procedure described in Fig. 3, the stage of Wait 107 is controlled by interruptions, said stage being maintained until the arrival of an interruption generated by the arrival of a new audiovisual content 7.

Fig. 6 shows the procedure from the reception 104 of the acceptance signal 20c for access to the additional contents 16 by the user.

The user issues an acceptance signal 20c by means of a dedicated button 20a of the remote control 20 ', which emits an infrared acceptance signal 20c, picked up by the transducer means 20b and that transfers said signal to the processing means 2.

Consequently, the processing means 2 proceed to check 109 that the second audiovisual content 21 is activated, ignoring the acceptance signal 20c in case it is not activated, since in this case the first audiovisual content 7 would not have additional content 16, interpreting that the acceptance signal 20c has been an error on the part of the user and ignoring it. If the icon 21a is activated, and consequently the first audiovisual content 7 has additional content 16, previously checked in the comparison stage 103, the recovery stage 110 of the locators 18b is proceeded to access the additional content 16 To optimize the speed of recovery, it is desirable that during the previous stage of comparison 103 the locator 18b has already been recovered from the database 15 and stored in memory or that information is available for the rapid extraction of the locator 18b, as for example the relative index of the pair of predefined data 17 of the database where the locator 18b or a pointer to the locator 18b is located.

Usually, a single locator 18b will correspond due to a positive comparison result in the database 15, however more than one locator 18b can be assigned to the same title 9, although it should be taken into account that the additional contents 16 designated by the locators 18b will be simultaneously executed and displayed at user with the consequent depletion of resources of the device 1, so that developers and managers of additional content must bear in mind the burden that this will place on the processing means 2 and, therefore, limit the number of additional contents 16 that can be shown simultaneously so as not to affect the expected performance of device 1.

At the end of the recovery stage 110 of the locator 18b, the additional contents 16 must be accessed and generated from the action related to the type of locator 18b, that is, check if the locator designates a local action 111 and accordingly execute said local action or if the locator 18b specifies a remote action, access a remote resource 112 through the means of communication 4 in order to generate 113 the visual event 26 from said additional content data 16. Through the means of communication 4 a bidirectional connection is established, between the device 1 and the service provider 12, which can serve the data of the additional contents 16 or act as a gateway, connecting the device 1 with other servers 13 that can serve said additional contents 16, acting as remote data sources 19, and that are connected to the service provider via a communication network 22 IP, as per Internet example. Naturally, all interconnected servers can use known encapsulation and encryption techniques to achieve the right level of privacy and security. Consequently, the resulting network topology in the system is the one shown in Fig. 7, where a plurality of devices 1 that receive radio frequency signals 24 from emitting stations 27 are interconnected with each other through the service provider 12. This allows that the additional contents 16 can even be obtained from another device 1 or that they can use the exchange of information between devices 1 as part of the interactivity offered by the additional contents 16, as for example in applications of Instant messaging or file sharing.

With the information obtained, the device 1 organizes the presentation of the additional content 16, which may incorporate part or all of the first audiovisual content 7, as well as other supplementary audiovisual contents and generate the output signal 23 that is sent to the television 10 'to be displayed to the user

The visual event 26 generated from the additional content data 16. can incorporate interactive fields that the user can activate by means of second peripheral devices 20, such as the remote control 20 ', a keyboard or a mouse, the latter not shown.

Naturally, it is also possible to configure the device 1 so that the acceptance signal 20c of the user is not necessary to locate and display the visual event 26 generated from the additional content data 16. In this case, when the presence of an additional content 16 associated with a first audiovisual content 7 that is being broadcast, the presentation of the additional content will be automatically generated following the steps described above and the output signal 23 sent to the television 10 '. For this purpose, the device 1 has a configuration menu where the user can also configure the types of additional content 16 to which he wishes to subscribe and, therefore, be notified as soon as they are available.

Fig. 4 shows the output signal 23 generated by the device 1 comprising a second audiovisual content 21 in the form of an icon 21a when a first audiovisual content 7 is broadcast whose title 9 is "producer and the database 15 contains a pair of predefined data 17 whose keyword 18a is "productol".

Since the predefined data pair 17 has previously been registered with the keyword 18a "productol" associated with the locator 18b "http://prod1.tv/tv.html", together with the first audiovisual content 7 of the advertisement, a icon 21a to warn the user that he has additional content 16. Then, if the user, by means of the remote control 20 ', it sends the acceptance signal 20c to the device 1, the visual event 26 generated from the additional content data 16 designated by the locator 18b through the navigator is shown on the television screen 10' device web 1. That is, the content of the "tv.html" file of the network address "prodi .tv" obtained through the media 4 and through the service provider 12 is shown on the television 10 ' as shown in Fig. 8. By means of a second peripheral device 20 such as a remote control 20 ', it is possible to navigate, using for example the pointer 32 through the links 28, 29 that the web page presents, interacting if necessary with the different network elements 1, 12, 13 interconnected, sending and receiving information in the known way in the network applications. Naturally, other navigation means known in the state of the art, such as active areas that can be controlled by the remote control 20 ', can be used to navigate through links 28,29.

As can be seen in Fig. 8, the first audiovisual content 7 can continue to be shown on a portion of the television screen 10 '. To display only the first audiovisual content

7, that is to say the television program received through the radio frequency signal, the user sends, by means of the remote control 20 'a signal that is received by the transducer means 20b and transferred to the processing means 2, which close the applications that are being used to display additional content 16 and that are no longer necessary. In this case, only the first audiovisual content 7 is sent back to the television 10 ', which if it is related to additional content 16, will incorporate the second audiovisual content 21. In the manner described above, the locators 18b can lead to show additional content 16 exclusive to users of device 1, where you can enter promotions and participate in contests

Other additional contents 16 may even allow communication between users of devices 1 by establishing a message exchange server, as shown in Fig. 9, in which the additional contents are shown superimposed on the first audiovisual content 7 .

For this purpose, a locator 18b containing both

The local messaging application to be executed as the server 13 in which the messaging server is located. In this case, communication can be established by exchanging text messages between different users, so that text messages appear

30 sent by other users and a field 31 is available to enter the text message to be sent. Naturally, users can use identifiers 33, both in graphic form and by means of a user name, as is known in the state of the art.

Other variants of the additional contents 16 can show real-time statistics of sporting events, send breaking news, show detailed information or offers related to a particular advertised product.
