DESCRIPTION
Receiver.
The present invention relates to receptors such as multi-carrier receptors and cellular receptors.
Cellular receivers in the form of portable radiotelephones are well known, and their design and operation are well understood. Such portable radiotelephones can be used to make and receive phone calls, send and receive messages, and even browse computer networks, such as the Internet. There are multiple standards for portable radiotelephones, including so-called "global mobile communications system" (GSM) or "general packet radio service" (GPRS).
Receivers capable of receiving digital television signals are also well known, such as signals broadcast in accordance with the “Digital Video Terrestrial Broadcasting” (DVB-T) standard.
The use and operation of user decoders (STB) to receive digital video broadcasts (DVB-T) are also well known. Such set-top boxes are capable of receiving a large number of digital television channels, data, and other interactive services.
Patent US 605145 describes a system by which a TV set can be controlled via a wireless network.
The invention, defined in claims 1, 6, 10 and 14 will now be described, by way of example, with reference to the accompanying diagrams, in which:
Figure 1 is a block diagram of a typical receiver / transmitter arrangement intended for consumer use; Y
Figure 2 is a block diagram of a first embodiment according to the present invention.
Figure 1 represents a block diagram of a typical receiver / transmitter arrangement intended for consumer use, in which a digital terrestrial video (DVB-T) transmitter 150 outputs a DVB-T signal to a DVB-decoder receiver. T 106.
At transmitter 150, a series of television channels 154 and 156 are multiplexed along with various data channels 158 and 160 by multiplexer 152. In addition, service information (SI) 162 is also sent, containing details of each of the other multiplexed channels, to the multiplexer 152, said information being provided by an SI generator 164. The multiplexer generates a single multiplexed signal 166 containing all independent channels 154, 156, 158 and 160, together with SI 162. Information can be found in the DVB-T specification (EN 300 468), incorporated into this document by reference. additional on multiplexing and SI. The multiplexed signal 166 is transmitted by an antenna 164, through a transmission channel, to an antenna 102 corresponding to a decoder receiver 106. In the case of DVB-T, the transmission channel is a terrestrial transmission channel. However, the transmission channel could alternatively be a satellite, microwave, cable or optical channel.
The signals received by the antenna 102 are sent to a DVB-T receiver 100 that allows the user to select the desired channel. The received data can also be stored in a memory 104.
When the decoder 16 is connected, the DVB-T receiver 100 is also connected and receiving DVB-T signals. The DVB-T receiver is constantly decoding SI information, which provides details about the content and placement of each of the channels within the multiplexed signal received. The SI information also contains details about the programming of each of the multiplexed channels. Programming information allows the user to watch or record a specific program of interest. For example, if the set-top box 106 is connected to a personal computer (not shown) it will be possible to receive the data transmitted through the DVB-T network for use with the personal computer. In this way, the transmission of large data files can be broadcast to a wider audience using the high data transfer rates provided by DVB-T transmission. If a data file is to be transmitted at a specified time on a specific channel, the information WILL contain this information, which can be used by the personal computer to ensure that the receiver receives the necessary data.
The SI information can be changed frequently, so that it reflects not only the changes introduced in the programming, but also the reassignment of frequencies and channels, etc. by the broadcaster. For example, a channel may broadcast on a different frequency than originally programmed. Given that the SI includes details about frequencies (or frequency changes), a receiver should always be able to receive the desired channel and / or program. Some decoders store SI information in memory, thus allowing users to navigate through a program or schedule guide. However, due to the nature of SI information, it is frequently updated to ensure that there are no discrepancies between the SI stored in the decoder and the SI transmitted by the broadcaster.
Figure 2 shows a block diagram of a first embodiment according to the present invention. A mobile terminal 200 receives DVB-T transmissions from a DVB-T transmitter 272. The transmitted DVB-T signal is a multiplexed signal generated by a multiplexer 250. The multiplexer 250 accepts as inputs various channels 252, 254, 256 and 258 to generate the multiplexed signal. The channels can be television, audio or data channels. The Service Information (SI) data, which contains information about the multiplexed channels, is also sent to the multiplexer 250. The SI data is generated by an SI generator 260, which may be a database that includes information about programming and location details for each of the channels.
The DVB-T signals are received through an antenna 210 of the mobile terminal 200 and are received and decoded by a DVB-T receiver 202.
Furthermore, and advantageously, the mobile terminal also receives an interactive channel from a cellular network or other type of transmission network 274 in a cellular transmitter / receiver 206. The cellular transmitter / receiver 206 allows both the reception and the transmission of the signals between mobile terminal 200 and cellular network 274. The cellular network may be
ES 2 227 254 T3 a GSM network, a general packet radio service (GPRS) network, a third generation (3G) network or other suitable network.
The SI data generated by the SI generator 260 is also supplied to a profiler 262 of the cellular network 274. The profiler contains a database with information about each of the subscribers to the cellular network 274. The Profiler can also contain information such as demographics, income levels, sports or leisure hobbies, etc.
The operation of a first embodiment of the present invention will now be described by way of example.
According to the prior art, if a user wishes to receive a “video clip (video sequence)” every time his favorite football team scores a goal during a football match, it will be necessary for the DVB-T 100 receiver of the DVB decoder -T 106 is constantly on and is constantly receiving SI data. This is because the exact moment when a goal will be scored is not known in advance. For this reason, the SI will not contain the programming of this type of event among its data. Consequently, the DVB-T receiver will have to wait for the SI data to indicate when the video clip is to be broadcast. If the user is interested only in receiving video clips of the football match, this method is especially ineffective in terms of electricity consumption, especially in the case of mobile terminals, since the DVB-T receiver is waiting, consuming electricity, to emit a specific video clip.
According to a first embodiment of the present invention, as shown by way of example in Figure 2, the subscriber communicates to the profiler 262 of the cellular network 274 that he is interested in receiving video clips. The DVB-T receiver 202 of the mobile terminal 200 can then be switched off. When a goal is scored, and a video clip is available for broadcast, the station must program the video clip to include it in the existing DVB-T multiplex signal. This may lead to the reprogramming of existing programs, and consequently, the updating of the SI data. Once a video clip broadcast schedule has been established, cellular network 274 will send a service announcement to cellular sender / receiver 206. The service announcement is received by sender / receiver 206 and processed by controller 204. The controller communicates to the DVB-T receiver 202 when the video clip is to be broadcast, as well as other relevant associated data, such as channel location, encoding parameters, etc. The DVB-T 202 receiver can be connected and configured in time to receive and decode the video clip. The video clip can also be stored in a memory 208. Once the desired video clip, or any other data, has been received, the DVB-T receiver 202 can be switched off again.
The service announcement may take the form of SI data, or alternatively, it may take the form of a short message (SMS) containing the time and location information required by the DVB-T receiver. Alternative forms of service announcement can be used, both in relation to the data to be sent and the protocol used to send it.
In this way, the DVB-T receiver 202 can be turned off when not needed for actual data reception. This can lead to significant savings in energy consumption, compared to the system used by the prior art.
The profiler can also control whether the requested information is transmitted to a user via DVB-T or cellular network. For example, if a million people have requested to see a video clip with the goals of a certain football match, it would be better to transmit the video clip through the DVB-T network. For such a large number of users, the DVB-T network provides a very affordable means of delivery. The alternative would be to individually send the video clip through the cellular network, which, with so many users, could adversely affect the operation of the cellular network.
If the number of users requesting to view a specific video clip is much smaller, it might be cheaper to send it individually over the cellular network. The exact thresholds will vary depending on the price structure of the DVB-T and cellular networks, as well as the number of users requesting a specific item and the volume of data to be sent.
Cellular transmitter / receiver 206 can also be used to return an acknowledgment to cellular network 274, indicating whether the video clip has been received correctly. This function can be used for billing purposes, as well as to request that the video clip be resent, in case it was not received due to poor signal strength, etc. The video clip can also be forwarded again in this case via the DVB-T network or the cellular network, depending on demand and profitability.
A further advantage of the present invention is that if the schedule announcements are sent over the cellular network, it will be possible to remove some or all of the SI data from the DVB-T network. Taking into account that normally the SI data usually occupies up to 3Mbits<sup>-1</sup>, this redundant bandwidth could be used to supply additional data or video channels.
In another embodiment of the present invention, a profiler may be included in the mobile terminal 200, in addition to the profiler 262 of the cellular network 274. A profiler located in the mobile terminal may be used if the communications network used for the interactive channel supports data transmission, as in the case of a GPRS network or any other packet network. The profiler can be configured according to user preferences, and will only accept service announcements that match user preferences.
Those skilled in the art will realize that although the present invention has been described above with reference to DVB-T transmissions, the invention is not limited thereto. The same techniques could be applied to DVB (satellite) reception and transmission or to any other similar or equivalent standards. Similarly, references to cellular networks and cellular transmission techniques could be replaced by another suitable type of communication network.
It is clear from the foregoing that the present invention is not limited to the provision of television content. In fact, as noted above, digital video broadcasts can
ES 2 227 254 T3 provide data services or other types of interactive services.
For example, the present invention can be used by remote banking and other customer-oriented services to improve the transmission of data, including Internet pages, to their subscribers. For example, a remote banking service could carry out its broadcasts using information pages broadcast on the network that contain high-quality graphics, standard texts, and so on. Each page could then be personalized using personal data transmitted through an interactive channel provided by a second network, such as GSM, GPRS or another network of a future generation. For example, a generic “balance” containing the bank's logo, background images, etc. could be transmitted to all users. The personal balance data transmitted through the interactive channel could then be combined with the transmitted "balance" to present the user with their own personal balance.
