Title: Receiver and method for controlling receiver

Description:
FIELD OF THE INVENTION  
       [0001] The present invention relates to a television set, a set-top box, and other receiving devices. Especially, the invention relates to a receiving device that has two or more receivers with different functions.  
       BACKGROUND OF THE INVENTION  
       [0002] Conventionally, a receiving device such as a television set or a set-top box had only one receiver. Among VTRs (video tape recorders), there were some that had two receivers or tuners. And, while users view and listen to a program, such VTRs had a function allowing the recording of a program on a different channel. However, the purpose of the two receivers or tuners was to select either one of program signals from the frequencies that were transmitted. Such receivers or tuners had basically the same functions.  
       SUMMARY OF THE INVENTION  
       [0003] In a conventional television set, video tape deck, set-top box, etc., despite the existence of two receivers or tuners, all of the receivers or tuners were controlled only through the receiving device. This is to say, it was possible to control whether receiving would be performed by the receiving device or not, and in case that receiving was to be performed, which channel should be selected, etc., only through the receiving device. Therefore, it was impossible to control the receivers from a broadcasting station, etc. as a transmitting party. So, even though the receiving device was equipped with a data storage part, no data could be freely stored by a transmitting party. Also, a transmitting party of a program could not select the programs that were shown on a display or the programs stored in a storing device.  
       [0004] In order to resolve this problem, in the present invention, the receiving device has been equipped with more than two receivers. Users can freely change the channel of one of the receivers, and cannot change a channel of another receivers, in principle. Yet, a party transmitting data, such as a program, can control it. Also, data received from another receiver can be automatically stored, where the data to control each function of receiving device itself and advertisements for companies can be stored and utilized from time to time.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
     [0018]FIG. 3 is a schematic of the system, including the receiving device  300  of the present invention. The data for a program, etc. is received by the receiving device  300  of the present invention, the data received is partially stored or transmitted to the receiving data-processing device  301 , and processed into a signal for presentation on a display, or processed into a voice signal. And the data is transmitted to the display unit  302 , etc., where it can be displayed to be viewed and listened to by users. The present invention relates to the receiving device  300  in the receiving system  303 . More specifically, the present invention relates to a receiving device shown in the functional block of FIG. 1.  
     [0019] As shown in FIG. 1, the receiving device  100  of the present invention includes a first receiver or tuner  101 , a second receiver  102 , a command recipient element  105 , a change control element  103 , a storage control element  104 , and a data storage  106 . The first receiver  101  receives a primary data, and the second receiver  102  receives a secondary data. The primary data could be, for instance, a movie, and the secondary data could be, for example, an advertisement for an automobile owned by a leading character appearing in the movie. The data storage  106  stores the data. A hard disk, RAM, cache memory, ROM, DVD, or FDD will do for the data storage  106 . The command recipient element  105  receives a command to change a channel, which the first receiver  101  receives. The storage control element  104  stores the data received by the second receiver  102  in the data storage  106 . Such functions operate as shown in FIG. 2.  
     [0020] As shown in FIG. 2, hypothetically, the first receiver  101  receives a program on the channel  1 . When users desire to change to the channel  2  on the television  202 , the command to change the channel is given to the command recipient element  105  by a remote control unit, etc. The command recipient element  105  is a part to receive a signal of the remote control  201 , etc., and in case that the remote control  201  is an infrared remote control, the command recipient part is an infrared light-receiving part and a signal-processing means incidental thereon, etc. When the command recipient element  105  receives a command to change a channel to the channel  2 , the command to change is passed over to the change control part, and control to change the channel at the first receiving part is performed. As a result, a program of the channel  2  is also displayed on the display unit. In such case, the data received by the second receiver  102  is stored in the data storage  203 .  
     [0021] A situation where a channel at the first receiver  107  is changed by the change control element is shown in FIG. 4. For example, when the first receiver  400  is able to receive the data of the channels  1  to  3 , the channel received by the receiving device can only be one of them. Therefore, the first receiver  400  must select one from among them. For this selection, the first receiver  400  has the means to acquire a command to control change  401 , and the means to change a channel  402 . The means to acquire a command to control change  401  acquires a command to change from the change control part, and the means to change a channel  402  changes a channel in accordance with such command to change.  
     [0022] Changing a channel here means tuning into the carrier wave carrying an analog terrestrial signal, which is utilized for conventionally existing television broadcasting as shown in FIG. 5. For instance, this means that tuning into the same frequency is changed from f1 Hertz to f2 Hertz. In addition, this also includes changing the URL of a broadcasting station in the case of the internet broadcasting, for example, from ‘http://www.abc.co.jp’ to ‘http://www.efg.co.jp.’ And in case that multiple channels are multiplexed and transmitted in the TDMA method by using packet communication or ATM communication, it involves selecting the packet or cell based on the management information added to the header, etc. For example, a specific type of packet or cell is selected by an identifier, which is included in the header, etc.  
     [0023] On the other hand, the second receiver receives the secondary data, which is stored in the data storage part by the storage control part. As shown in FIG. 6, the data received by the second receiver includes a control signal so as to control the functions for the receiving device, the receiving data-processing device, display unit, and the devices attached to this system, for example, a control signal so as to compress and save the storage medium data. And it includes advertisement information so as to have the users view and listen thereto by showing such information on the display unit as well as a program, for example, an advertisement for an automobile manufactured by T company. It further includes a program so as to cause the receiving device, the receiving data-processing device, the display unit, etc., to execute specific processes, for example, a program to perform the word processor function. And it includes the item which constitutes a part of a program, such as dynamic link library and the like. It further includes a signal in order to transmit urgent information such as that regarding earthquake or disaster, for instance, information about evacuation areas at the time of a disaster.  
     [0024] Such data is commonly transmitted from a transmitting station to the entire receiving system under the control thereof by broadcasting. Additionally, the data received at the second receiver may be an individual signal such as a telephone signals or electronic mail exchanged among the receiving systems. The signal received at the second receiver is stored in the storage, which makes it available to access and use any time thereafter. Additionally it creates an effect that makes it possible to use such signal as many times as possible, not only once, as long as it is stored.  
     [0025] For instance, once an urgent signal is stored, such as one regarding earthquakes or disasters, even if a broadcasting function such as a broadcasting station is suspended, it is possible to access such signal, and it is convenient for information that is necessary to confirm several times, such as guidance to evacuation areas, or information about the range of the disaster. Additionally, advertisement information for a company will not be changed every time it is shown on the display, and once it is stored, it is possible to access it from the storage device any time thereafter, and show it on the display conveniently.  
     [0026] Causing this type of information to be included and transmitted in the data received by the first receiver, it may be possible to believe that the information is received at one receiving device, is signal-processed internally, and is processed. However, a program, etc. is organized at a broadcasting station once and a reconfigured signal is transmitted, in order to pass the management signal, advertisement, or urgent information to the broadcasting station, and make a reconfiguration thereof. This is inconvenient in that it takes a large amount of time and effort.  
     [0027] Furthermore, control of the first receiver is basically entrusted to users. Therefore, in order to cause anyone to view and listen to content which must be to viewed and listened to, such as urgent information, it would be more convenient to separate the receiving device into more than two elements, and control them separately from the device receiving the data, such as general programs. It is convenient to use a configuration such that users cannot exercise a control such as changing the channel of the second receiver, etc., for example.  
     [0028]FIG. 7 shows a case where the data received by the second receiver  702  is an advertisement for a company. The data 1 ( 706 ) received by the first receiver  701  is shown as a program on a large part of the display, for instance, in an area comprising 70-90% thereof, via the receiving data-processing element  704  and the display  705 , and users view and listen thereto. At the same time, the data 2 ( 707 ) received by the second receiver  702  is stored in the data storage  703 , is transmitted to the receiving data-processing element  704 , and is shown on the remaining part of the area not occupied by the data 1 ( 706 ), via the display  705 .  
     [0029] Because such data is an advertisement, it is shown on the display to the extent that it does not disturb the viewing and listening to a program by users. Regarding this advertisement for a company, the data is received by the second receiver  702 , and may be displayed simultaneously therewith. Alternatively, after the data is stored in the data storage  703  once, the data may be displayed. Therefore, even when the second receiver  702  does not receive the advertisement, the data can be viewed on the display by extracting the data from the data storage  703 .  
     [0030] Next, the data reception by the secondary data receiving part and a command to change a channel is explained. As shown in FIG. 8, the receiving device includes a first receiver  801 , a second receiver  802 , a change control element  803 , a storage control  804 , a command recipient element  805 , a data storage  806 , and a second change control  807 . The second receiver  802  receives data and a command to change a channel. A command to change a channel relates to the second receiver  802 . The basic functions of the first receiver  801 , the change control element  803 , the command recipient element  805 , the storage control  804 , and the data storage  806  are the same as the functions of the receiving device, which has been explained hereinabove.  
     [0031] The second receiver  802  receives data and a command to change a channel, and the second change control element  807  controls the changing of a channel of the second receiver  802  based on the command to change a channel received at the second receiver  802 . The second receiver  802  receives a signal from the second change control element  807 , and performs the changing of a channel by configuration shown in FIG. 9. As shown in FIG. 9, the second receiver  900  is composed of the second means to acquire a command to control change  901  from the second change control part and a means to change a channel  902  based on a command to change from the second means to acquire a command to control change  901 . In case that channel  1  is selected by the means to change a channel  902 , the data of channel  1  is stored in the data storage part  903 . When a channel is changed, data concerning the channel which has been changed is stored in the data storage part  903 .  
     [0032] This situation is shown in FIG. 10. In case that the receiving system including the receiving device is a television set, the second receiver of the receiving device for the television set  1001  initially receives the data of the advertisement for the T company, and stores the data at the data storage  1003 . However, receiving a command to change a channel at the second receiver of the receiving device for the television  1002 , a channel will be changed to the channel of the advertisement for the N company, such data will be received, and be stored in the data storage  1004 . In the meantime, a program not related to the advertisement may be displayed on the television set. Alternatively, while the advertisement for the T company is initially displayed, and with a command to change a channel, a process for the advertisement of the N company to be displayed may be made. In addition, the form of the implementation of this invention indicated above shows an example of this invention, and is not given with the purpose of restricting the scope of rights for this invention. The scope of rights for this invention is not limited by such examples, and includes all forms of implementation that are applicable.  
     [0033] Next, the control method for the receiving device is explained. As shown in FIG. 11, firstly, an input for receiving is waited for (Step S 1101 ), and after the input is made, it is determined whether a command to change a channel is made or not (Step S 1102 ). After the command to change a channel is made, a channel of the first receiver is changed (Step S 1103 ). Secondly, it is determined whether there is reception of the data by the second receiver (Step S  1104 ), and in case that there is reception of the data, such data is received (Step S  1105 ), and the processing is completed.  
     [0034] Also, as shown in FIG. 12, the data received by the second receiver may always be stored in the data storage. The process indicated in FIG. 12 shows that an input for receiving is waited for (Step S  1201 ), and after the input is made, it is determined whether a command to change a channel is made or not (Step S 1202 ). After the command to change a channel is made, a channel of the first receiver is changed (Step S 1203 ). Secondly, it is determined whether data of the second receiving part is received (Step S  1204 ). In case that there is reception of the data, such data is received (Step S  1205 ), and the received data is stored at the data storage (Step S  1206 ), and the processing is completed.  
     [0035]FIG. 13 explains a case where a signal to change a channel is received by the second receiver is received at the second receiver. An input for receiving is waited for (Step S  1301 ), and after the input is made, it is determined whether a command to change a channel is made or not (Step S 1302 ). After the command to change a channel is made, a channel of the first receiver is changed (Step S 1303 ). Secondly, it is determined whether there is reception of the data of the second receiver (Step S  1304 ), and in case that there is reception of the data, such data is received (Step S  1305 ) and the received data is stored at the data storage (Step S  1306 ). Furthermore, it is determined whether there is reception of a command to change a channel at the second receiver (Step S  1307 ), and in case that there is reception, a channel of the second receiver is changed (Step S  1308 ), and the processing is completed.  
     [0036] Such processes are not necessarily performed at the receiving device or receiving system, and may be performed at peripheral equipment incidental thereon. In addition, it would be convenient to allow the program to execute the processes shown in FIG. 11 through FIG. 13 to be the recording medium, which is recorded to be readable by computer. The definition of being readable by computer includes being readable by the receiving system or the receiving device.  
     [0037] The present invention can receive a signal to control the receiving device itself or an advertisement for a company, in addition to programs for viewing and listening to. Therefore, it is possible for a transmitting party of the program to control the receiving device and the receiving system itself. For instance, despite the presence of a program that is viewed and listened to, it is possible to show the advertisement for a company on the display.
