Definitions

• the present invention relates to a digital television and / or audio reception device and a mobile processing unit.
• STBs set top boxes
• digital broadcast systems are capable of transmitting data with a high bandwidth from a broadcast station of a provider to a multitude of receivers, i.e. STBs, using for example a satellite link, a cable network or a terrestrial digital broadcast.
• the high bandwidth allows to include additional data in the stream of television and / or radio signals, for example additional information about an ongoing televi- sion show or electronic program guide information.
• the additional data is then forwarded from the STB to a mobile processing unit using for example an electromagnetic short range transmission standard such as BLUETOOTH .
• Such systems are for example known from the WO 2004/088983 A, the WO 2003/088027 A and the WO 03/088655 A.
• the control of the presentation of the additional data by the mobile processing unit is difficult for the user of the described systems.
• a mobile processing unit is typically not used for managing large amounts of structured data.
• the screen of a television system is regarded from a certain distance and does often not provide a sufficient resolution for the presentation of greater amounts of textual information or other complex media contents. This is one of the reasons, why the described systems are until now restricted to the presentation of a limited amount of content to a user of the mobile data processing unit.
• a digital television and / or audio reception device comprising a receiving unit adapted to receive a digital television and / or audio signal, the signal including an additional data stream for content to be presented by a mobile processing unit, in particular a mobile phone, an output unit for a first display means, in particular a television set, connected to or integrated with the digital television and / or audio reception device, the output unit adapted to output a signal for the display of a first plurality of selectable items on the first display means, and a transceiver unit adapted to send electromagnetic signals to the mobile processing unit, the electromagnetic signals causing a second display means of the mobile processing unit to display a second plurality of selectable items, wherein the second plurality of selectable items depend on a selected one of the first plurality of selectable items displayed by the first display means.
• the transceiver unit is further adapted to receive a request from the mobile processing unit for the content in response to the selection of one of the second plurality of items displayed by the second display means of the mobile processing.
• the transceiver unit is further adapted to send the content to be presented by the mobile processing unit in response to the selection of one of the second plurality of items displayed by the second display means of the mobile processing unit.
• the digital television and / or audio reception device therefore splits the navigation of the content between the first display means, for example the screen of a standard television set, and the second display means of the mobile processing unit.
• the electromagnetic signals exchanged between the digital reception device and the mobile processing unit provide a seamless link of the information presented on the two display means.
• a user trying to navigate through complex additional data content of a digital broadcast system is intuitively guided from the initial navigation steps on the first screen to one or more further navigation steps using the mobile processing unit.
• the transceiver unit of the digital television and / or audio reception device is further adapted to receive control signals from the mobile processing unit for the selection of one of the first plurality of selectable items displayed by the first display means.
• the digital television and / or audio reception device may even be essentially fully remote controlled by the mobile processing unit.
• the mobile processing unit effectively replaces the standard remote control of the digital reception device (and possibly also of the attached or integrated television set) so that a user does not have to changeover between different input means for the navigation of the additional data.
• the set up of the communication between the mobile data processing unit and the digital reception device can be significantly facilitated, if the transceiver unit is adapted to transmit control software to the mobile processing unit enabling the mobile processing unit to operate as mentioned above.
• the receiving unit of the digital reception device is capable to receive the control software in the additional data stream included in the digital television and / or audio signal.
• the control software might for example be included every few min- utes in the data carousel of the digital broadcast system so that it is almost immediately available for download from the digital reception device to the mobile data processing unit.
• the control software can also be downloaded via a communication network based, for example, on the GSM or UMTS standards, etc. to which the mobile data processing unit is connected, for example in response to an initializing SMS message to a provider.
• the transition of a user from the first display means connected to the output of the digital reception device to the second display means of the mobile processing unit is particularly easy, if the output unit is further adapted to output a signal for the display of a message on the first display means drawing the attention of a user to the second display of the mobile processing unit after one of the first plurality of selectable items has been selected.
• the transceiver unit When a user wants to obtain different content to be presented by his mobile data processing unit he may change the selected one of the first plurality of selectable items. This causes preferably the transceiver unit to send electromagnetic signals to the mobile processing unit, which in turn cause the second display means of the mobile processing unit to display a different second plurality of selectable items.
• the selections available on the second display means are prefera- bly like a submenu dependent on the selection of the user in the main menu, i.e. among the first plurality of selectable items.
• the present invention relates to a mobile processing unit, in particular a mobile phone, comprising a first transceiver unit for commu- nicating with a digital television and / or audio reception device as described above and a second display means to display a second plurality of selectable items, wherein the second plurality of selectable items depend on a selected one of a first plurality of selectable items displayed by a first display means connect to or integrated with the digital television and / or audio reception device; and wherein the first transceiver unit is adapted to receive content from the digital television and / or audio reception device in response to selecting one of the second plurality of items.
• the mobile data processing unit is the counterpart of the digital reception device of the present invention.
• the first plurality of selectable items are displayed by a first display means such as a television set
• the second plurality of selectable items is displayed (and one of the items may finally be selected) under the control of the mobile processing unit.
• the split of the navigation between the first display means and the second display means of the mobile data processing unit avoids a large number of menu layers to navigate with the mobile processing unit. Therefore, a user may obtain the desired content from the digital reception device, for example a news article, on the second display of his mobile processing unit after pressing only a few buttons.
• the first transceiver unit is further adapted to transmit a signal to the digital television and / or audio reception device causing a selection of one of the first plurality of selectable items displayed in the first display means.
• this option allows essentially to replace the standard remote control of the digital reception device and an attached or integrated television set.

• a return channel is provided, using preferably a mobile communications network 300 to which the mobile phone is attached, hi the illustrated example, SMS messages are used as a return channel, which are received by an SMS service provider 310 and forwarded to the content provider 10 to create a closed feedback loop.
• the broadcast signals may for example be only audio signals of a digital radio broadcast.
• a cable network or a digital terrestrial broadcasting system may be used to transport the convoluted signal from the broadcaster to the STB 100 instead of or in addition to the satellite link 30.
• the specific convolutional technique used to combine the TV and / radio signals with the additional data may also vary but is preferably in agreement with the relevant standards (DVB, DAB, DVB-T, etc.).
• the transmission between the STB 100 and the mobile phone 200 uses preferably a BLUETOOTH ® based communication 150. However, other transmission techniques using for example infrared light or a WLAN are also conceivable.
• the return channel is only optional and can be realized in a number of different ways using instead of SMS messages a data channel of the mobile communications network, the technical details of which depend on the respective network standard (GSM, GPRS, UMTS etc.). Since the person skilled in the art is aware of the wide variety of possible hardware implementations possible for the transceiver units of the STB 100 and the mobile phone 200, these units are not described in further detail and not specifically shown in the figures.
• the STB 100 may be a standard STB, separate from the television system 102 or be integrated with this device. Apart from the specific functionality described below, the STB 100 operates for processing the received TV signals in a manner, which is well known in the art. Further, the STB 100 filters out the additional data to be transmitted to the mobile phone 200 using standard techniques, as they are for example described in the prior art documents mentioned in the introductory part or in the above mentioned EP 1 650 971 Al of applicant.
• the mobile phone 200 is only one example of a large variety of mobile processing units, which can be used in the context of the present invention.

• the user tunes the STB 100 preferably in a first step to a dedicated channel using for example its remote control (not shown).
• the dedicated channel may for example be accessible as "channel 0" on the remote control.
• the user can select among a plurality of different categories of additional data, concerning in the pre- sented exemplary embodiment entertainment, news, shopping and TV-channels.
• the embodiment of Fig. 1 uses a frame cursor 111 to highlight selected items, there are other options for an optical indication, which are know to the person skilled in the art.
• Selecting one category in the menu 110 of Fig. 2 leads to the presentation of a submenu 120, as exemplary shown in Fig. 3.
• a submenu 120 is displayed with a plurality of lotteries, which can be selected for watching the latest draw or related lottery information. Again, a frame cursor 111 is shown, which allows to select one of the pluralities of lotteries.
• the standard remote control of the STB 100 and / or the television set can be used to navigate the menus 110, 120 shown in Figs. 2 and 3.
• the mobile phone 200 can be used for the navigation through the menus 110, 120 presented on the screen 102 of the television set. To this end, the mobile phone 200 sends corresponding commands via the BLUTOOTH ® link to the STB 100, which are received and processed, wherein the results of the commands, however, are still presented on the screen 102 (for example moving the frame cur- sor 111 up or down).
• This mode of operation may be more convenient, since the user will have to use the mobile phone 200 anyway for the further navigation steps described below.
• the last line 115 in the display 102 shown in Figs. 2 and 3 will be different and preferably inform the user which keys of his phone 200 are adapted to control the operation of the STB 100.
• the mobile phone 200 not only controls the STB 100 with respect to the navigation of the menus 110, 120 shown in Figs. 2 and 3 but fully replaces the standard remote control.
• the concept to control an STB and / or a television set via a mobile phone is fully independent from the split navigation of additional content and may be also realized for controlling the operation of any ordinary STB and / or television or radio set.
• the described example comprises only two navigation layers on the screen 102 of the televisions set (the menus 110 and 120), there may be less or more of such layers.
• the selection of the item "LOTTO.de” in the menu 120 leads to the navigation of the information being handed over to the mobile phone 200.
• the screen 102 presents preferably a message 130, which directs the user to his mobile phone 200, as exemplary shown in Fig. 6.
• the message 130 is only optional and there may be other ways of drawing the attention of the user to his mobile phone 200, for ex- ample an audio signal emitted by the phone 200 and / or a visual indication such as a blinking light or the like on the phone 200.
• the message 130 may be present on the screen 102 as long as the mobile phone 200 navigates the further menus as described below. Alternatively, the message 130 may only remain on the screen 102 until the user has started to actually use his phone 200 for the further navigation steps, which is reported by sending a corresponding report signal back to the STB 100 after the first keystroke on the phone 200. hi this alternative, the screen 102 may be used for other purposes, while the information concerning the selected item of the menu 120 is further navigated on the phone 200.
• the STB 100 may for example switch back to the last selected TV channel. Alternatively, the STB 100 may go back to present the initial screen of Fig. 2 and allow another user of a further mobile phone (not shown), which also communicates with the STB 100, to start the same navigation steps described above. Since BLUETOOTH ® is generally able to handle a plural- ity of devices communicating with each other, more than one mobile phone 200 can be linked to the STB 100 in the described manner for navigating complex information in order to obtain desired content.
• Fig. 4 presents an embodiment of an initial display of a screen 202 of the mobile phone 200.
• a part of the screen 202 presents an introductory message
• the message 210 facilitates the transition in the user navigation from the screen 102 of the television set to the screen 202 of the mobile phone 200.
• Another part of the screen 202 presents a further plurality of selectable items.
• this further plurality is shown as the menu 230. Selecting one item 231 of this menu 230 provides the desired content 250, which is in the example illustrated in Fig. 5 the numbers and quotes of the lottery draw of February 15, 2006. Other examples may comprise also nontextual information such as images, audio files or even video clips to be presented on the screen 202.
• the data of the content 250 is preferably sent from the STB 100 to the mobile phone 200 only in response to the above described final selection step.
• the STB 100 starts to transmit data already, when a certain submenu is presented to a user.
• the STB 100 may already start to transmit lottery data corresponding to all four items of the menu 230, when the menu 230 is presented to a user.
• An optimized approach for the decision when to transfer which data from the STB takes a number of parameters into account, such as the memory size of the mobile phone, which is available for the browser, the bandwidth of the BLUETOOTH ® link between the STB 110 and the phone 200, how often the data are updated from the content provider 10 etc..
• the STB 100 will store as little data in the phone 200 as possible.
• the details of navigating one or more menus 230 on the screen 202 of the phone will depend on the browser running on the mobile phone 200, which in turn depends on the hardware of the phone and possibly on an operating system, which provides an intermediate layer between the application software of the browser and the hardware of the mobile phone 200.
• the user wants to subsequently select a different content, he can move back in the menu structure presented on the screen 202 of the phone.
• the screen shown in Fig. 5 presents an option 260 "Back", which will bring the mobile phone 250 back to the menu 230 shown in Fig. 4.
• Moving further up, for example to a different category, can be achieved by directly navigating on the screen 102 shown in Fig. 6.
• a further menu 180 comprising among others the item "To portal”. Selecting this option (using the remote control of the STB or the mobile phone as discussed above) brings the user directly back to the initial screen of Fig. 2.
• the user can directly jump back to the general level and therefore easily and quickly reach new content to be presented on his phone 200.
• the screen 102 no longer shows the display of Fig. 6, for example, if the STB switched (automatically) back to a TV channel, there might be a command provided in the browser, which brings the screen 102 immediately back, either into the state of Fig. 6 or directly back to the state of Fig. 2.
• the screen 202 of the mobile phone 200 can either freeze the presented content or continue to present the content 250 until the navigation is handed back to the mobile phone 200, as described above with respect to Figs. 4 and 5. Again, this is a strategic decision, which depends, among others, on the memory size of the mobile phone 200 and the bandwidth of the BLUETOOTH ® link between the STB 110 and the phone 200.
