DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The present invention will be explained in terms of exemplary embodiment described in detail with reference to the accompanying drawings, which are given only by way of illustration and thus are not limitative of the present invention.
Fig. 1 is a map illustrating a broadcasting system in accordance with a preferred embodiment of the present invention applied to satellite broadcasting. A broadcasting system includes a broadcasting service provider domain, a subscriber domain and a mobile communication network 30. The broadcasting service provider domain comprises a broadcasting service provider 10, a broadcasting station 12, and a satellite 14. The subscriber domain comprises a broadcasting receiving device 20 including a mobile communication unit 22. The mobile communication network 30 comprises a mobile communication service provider (not shown), a mobile switching center MSC, home location resister HLR 32 and a base station.
The broadcasting service provider 10 transforms broadcasting programs which will be provided to subscribers into broadcasting signals, and delivers the signals to the satellite 14 via the broadcasting station (42). The subscriber receiving device 20 receives the broadcasting signals via the satellite 14 (42). When it has data to transmit to the broadcasting service provider 10, the subscriber receiving device 20 generates return data and transmits the return data into the mobile communication network 30 via the mobile communication unit 22. The mobile communication network 30 may be connected to the broadcasting service provider 10 wirelessly such as general mobile communication terminals. However, it is desirable to be connected to the provider 10 via a separate communication network such as optical transmission cable in order to receive return data transmitted from a plurality of broadcasting receiving devices 20, heighten security and receive additional information form the mobile communication service provider (46).
The return data from the broadcasting receiving device is not necessarily routed to the broadcasting service provider 10. If necessary, the return data may be routed to a program provider PP (not shown). For example, when a program provider offers home shopping service, return data is routed to the program provider via the wireless communication network 30. Fig. 2 is a block diagram illustrating a broadcasting receiving device 10 in accordance with a preferred embodiment of the present invention. Like a conventional device, a broadcasting receiving device 10 comprises a receiving unit 110, a control unit 120, an I/O interface unit 130, a memory unit 150, an output unit 132 and an input unit 134, and further comprises a mobile communication unit 160 for being connected to a return network.
Broadcasting data provided by the broadcasting service provider 10 is modulated into broadcasting signals via the broadcasting device 12 and transmitted into the receiving unit 110 of the broadcasting receiving device 10. Like a conventional receiving unit, the receiving unit 110 restores the received broadcasting signals into data having streaming form via down-converting, demodulation, error- correcting and decoding. The streaming data is suitable to administer in the control unit. The operation of receiving unit 110 is not explained because it can be embodied using the conventional art. Output data among broadcasting data is extracted in the control unit 120, and return information data is stored in the memory unit 150. In the I/O interface unit 130, the output data is modulated into output signals suitable to administer in the output unit 132, and the output unit 132 outputs the output signals to subscribers (in case of video data, via screen; in case of audio data via speaker). Here, subscribers can input user operation via the input unit 134 such as control panel, keyboard, pointing device or remote controller. The user operation inputted via the input unit 134 is 1) to generate input signals for controlling broadcasting receiving device 10 such as channel selection, and 2) to prepare selections of subscribers (e.g. orders of home shopping products, votes of particular subjects) into return data when broadcasting data supports an interactive function.
The input of subscribers is transformed into input signals such as electric signals via the input unit 134. The input signals are modulated into input data via the I/O interface unit 130 and transmitted into the control unit 120. The control unit 120 generates return data using input data by input of subscribers and return information data stored in the memory unit 150 in case of response to interactive function. More desirably, when it includes brief information, return data may be modulated into data having short message service SMS format such as CDMA and GSM. The SMS format data is defined in mobile communication protocol supported by the mobile communication unit 160. In order to identify from which broadcasting receiving device 20 return data is, return data may include one number selected from the group of a phone number given to the mobile communication unit 160, a MAC address given to the broadcasting receiving device, an identifying number given to subscribers or the combination thereof, as an identifier.
Return data is modulated into mobile communication signals suitable to the mobile communication network via the mobile communication unit 160, and provided. As described above, return data is routed to the broadcasting service provider 10 or the program provider according to return information included in return information data. The mobile communication unit 160 has a structure identical or similar to modem for mobile communication.
More desirably, the mobile communication unit 160 transmits and receives email data via the mobile communication network 30. In other words, the mobile communication unit 160 transmits the email inputted via the input unit 134 into the mobile communication network 30, receives the email via the mobile communication 30, and then outputs the email via the output unit 132 into subscribers.
Fig. 3 is a block diagram illustrating an I/O interface unit 130 and a remote controller 134 adding a phoning function in accordance with a preferred embodiment of the present invention. The broadcasting receiving device 20 comprising the mobile communication unit 160 may comprise a remote controller 134 adding a phoning function to offer subscribers phone service using mobile communication network via the mobile communication unit 160. The remote controller 134 comprises an IR transmitting unit 180, a local area wireless communication I/O 182, an input unit 186, a speaker 184 and a microphone 183. The I/O interface unit 130 comprises an IR receiving unit 172 and a local area wireless communication I/O 174.
The input unit 186 having various button keys serves as operation of subscriber receiving device 20 by subscribers or preparation of input data which becomes the base of return data. The IR transmitting unit 180 of the remote controller 134 and the IR receiving unit 172 of the I/O interface unit 130 are used to relay user input via the input unit 186 into the control unit.
The microphone 183 and the speaker 184 are used for phone calls of subscribers. The local area wireless communication I/O 174 and 182 are used to transmit and receive sound data between the remote controller 134 and the subscriber receiving device 20 when the subscriber is on telephone. This local area wireless communication may use one of various systems such as Blue Tooth, IrDA, Wireless LAN. The local area wireless communication should also ensure data transfer rate which can support sound communication and data transmission within feasible distance of remote controllers. Here, signals of the input unit 186 may be transmitted into I/O interface units using local area wireless communication I/O. In this case, the IR receiving unit 172 and the IR transmitting unit 180 may be omitted.
More desirably, the broadcasting service provider 10 includes return phone numbers related to broadcasting programs in return information data of broadcasting data, and transmits the numbers to subscribers. The remote controller 134 enables the mobile communication unit 160 to phone using the return phone numbers by subscriber input simpler than direct input of the return phone numbers. For example, when a home shopping program introduces a product requiring explanation on technical details, the broadcasting service provider 10 includes a return phone number of a person in charge of the explanation in broadcasting data in advance, and transmits the number to each broadcasting receiving device 20. The broadcasting receiving device 20 stores the return phone number in the memory unit 150. The subscriber requiring detail explanation of products pushes a predetermined key (telephone connection key) of the remote controller one time. The mobile communication unit 160 then phones with the return phone stored in the memory unit 150. Finally, the subscriber is phone-connected to the person in charge of explanation. The memory unit 150 of the subscriber receiving device 20 automatically memorizes return phone numbers included in each broadcasting data. As a result, subscribers can be phone- connected to people in charge conveniently by pushing one time a predetermined key without memorizing or inputting whole return phone numbers of each program. The control unit 120 further comprises a self-trouble detecting means 124 for detecting troubles. When the self-trouble detecting means 124 detects a trouble, the control unit 120 generates return data including particulars about the trouble and transmits the data into the mobile communication network 30 via the mobile communication unit 160. More desirably, if the self-trouble detecting means 124 transmits the particulars of troubles via the mobile communication network 30 into the broadcasting service provider 10, the broadcasting service provider 10 takes the necessary steps according to particulars of a trouble. As a result, it is not necessary that a subscriber in person then registers the trouble into the broadcasting service provider 10 or explains of particulars of the trouble, who do not know about the broadcasting receiving device.
A mobile communication service provider grasps the condition of broadcasting receiving device 20 on operation, and provides the grasped information for the broadcasting service provider 10. Like general mobile communication terminals, the mobile communication unit 160 periodically transmits access probe signals into the mobile communication network base station 30. The access probe signals registers its current location to home location resister HLR 32 of mobile switching center MSC. When the mobile communication unit 160 operates by interlocking to a power source of the broadcasting receiving device 20, the broadcasting receiving device 20 including the mobile communication unit 160 of which the access probe signals is received by the mobile communication network base station 30 may take the power source for ON condition. As a result, the broadcasting service provider 10 can administer subscribers effectively by receiving the information from the mobile communication service provider.
The mobile communication service provider grasps location information of broadcasting receiving device 20 on operation, and offers the location information to broadcasting service provider 20. The broadcasting service provider 20 may offer selectively broadcasting information corresponding with the location information to relevant broadcasting receiving devices 20, respectively. In other words, the broadcasting service provider 10 provides intelligent broadcasting services related to location for the broadcasting receiving device 20 because the location information of each broadcasting receiving device 20 is on real-time or periodically offered to the provider 10 from HLR 32 of mobile communication network 30. The intelligent broadcasting services include navigation, regional information for mobile broadcasting receiving device 20, and other itemized information such as weather, advertising necessary for each area. Fig. 4 is a flow chart illustrating a method of providing broadcasting service in accordance with a preferred embodiment of the present invention. The method of providing broadcasting service has three steps. The first step is when broadcasting data is an interactive demand signal, the second step when broadcasting data is a subscriber administering signal, and the third step when broadcasting data is subscriber output data.
The method of providing broadcasting service passes through the first step of receiving broadcasting data for the broadcasting receiving device 20 (S20). The signals may be transmitted via aerial waves such as general TV broadcasting, satellite broadcasting or cable network. The method passes through the second step of performing the process of managing interactive demand signals when broadcasting data is an interactive demand signal (S30). The interactive demand signal is to identify interactive broadcasting for replying input of users among broadcasting contents or to enable input of users. For example, in home shopping programs, the interactive demand signal replies orders into return data via the broadcasting receiving device 20. The signal also includes data for votes, polls, interactive movies and games requiring selection of subscribers.
The method passes through the third step of performing the process of managing subscriber administering signals when as a decision result of the second step (S30) broadcasting data is not an interactive demand signal but a subscriber administering signal (S40). The subscriber administering signal is to grasp the operation condition of broadcasting receiving device 20 irregardless of broadcasting programs which subscribers currently watch. This signal is to demand that the broadcasting receiving device 20 itself generates return data and replies the data without waiting for input of subscribers unlike interactive demand signals.
The method passes through the fourth step of outputting broadcasting data into subscribers when as a decision result of the third step (S40) broadcasting data is not a subscriber administering signal (S70). The signal as general broadcasting signal is transmitted in the same way when the conventional broadcasting receiving device 20 receives broadcasting signals. In other words, the image signals are transmitted into subscribers via screen of broadcasting receiving device 20, and the sound signal via speaker thereof.
However, the above-described process of managing interactive signals comprises the fifth step of waiting for subscriber input (S35), the sixth step of generating return data including subscriber input (S60) and the seventh step of transmitting the return data via mobile communication network (S60). As described above, in input unit 134, user operation is inputted. Return data is generated in control unit 120. The return data is transmitted in mobile communication unit 160.
When interactive demand signals include data for home shopping service, subscriber input of the fifth step S35 is input for selection of purchase products, and return data of the sixth and seventh steps S50 and S60 include information on the subscriber input and purchased products. When interactive demand signals include data for votes, polls, interactive movies and games, subscriber input of the fifth step S35 is input for selection of subscribers, and return data of the sixth and seventh steps include information on the subscriber input and purchased products.
Similarly, the process of managing subscriber administering signals comprises the eighth step of generating return data including information required by subscriber administering signals (S50), the ninth step of transmitting return data via mobile communication network (S60). When the subscriber administering signal requires information on channels that subscribers currently watch or watched for a predetermined period, return data of the eighth and ninth steps S50 and S60 may include information on channels that subscribers currently watch or watched for a predetermined period.
Desirably, the broadcasting receiving device 20 further comprises a phoning function. An interactive demand signal is a return phone demand signal. When the signal includes information on return phone numbers, subscriber input of the fifth step S35 is to phone with a return phone number using a simpler way than the way to directly input the return phone number. Return data of the seventh step may be data requiring phone connection to the return phone number via the mobile communication network. The relevant operation is omitted because it is previously explained in Fig. 3.
More desirably, the broadcasting receiving device 20 further comprises the self-trouble detecting means 124. In one step of the first through eighth steps S20-S60, when the self-trouble detecting means 124 detects a trouble, the method may further comprises the tenth step of preparing return data including information on particulars about the trouble, and the eleventh step of transmitting the return data into mobile communication network. As discussed earlier, broadcasting receiving device, digital broadcasting network and method of providing broadcasting service can ensure mobility and have remarkable effect to transmit a small amount of burst return data on real-time at a low cost, due to return network as mobile communication network. Because separate physical connection is not required, the device can be simply installed and mounted on vehicles and ships. According to a preferred embodiment of the present invention, the broadcasting receiving device further comprises a remote controller adding a phoning function, and a broadcasting system. In the broadcasting receiving device, the broadcasting data includes a return phone number related to broadcasting programs outputted to subscribers. The subscribers can phone via mobile communication network using the return phone number by simpler input than direct input of return phone number.
According to another preferred embodiment of the present invention, the broadcasting receiving device further comprises a self-trouble detecting means which can notify a broadcasting service provider of troubles via wireless communication network. As a result, subscribers need not check troubles and directly notify broadcasting service providers of the troubles. On the contrary, the device automatically notifies the providers of the troubles, thereby reducing waste of effort such as trouble notices. According to still another preferred embodiment of the present invention, broadcasting service providers can increase convenience of subscriber administration by receiving ON/OFF conditions of subscriber receivers and location information from mobile communication service providers, and offer intelligent broadcasting services to subscribers. According to still another preferred embodiment of the present invention, the broadcasting receiving device can grasp the condition of broadcasting programs that subscribers currently watch or watched for a predetermined period using return network via subscriber administering signals. As a result, broadcasting service providers can conveniently make an audience rating survey without performing any separate phone questionnaire or comprising any separate device for audience rating grasp.
While the invention is susceptible to various modifications and alternative forms, specific embodiments have been shown by way of example in the drawings and described in detail herein. However, it should be understood that the invention is not limited to the particular forms disclosed.
