Description

  The present invention relates to televisions, set-top boxes, and other receiving devices, and more particularly to a receiving device having two or more receiving units having different functions.

Conventionally, receiving devices such as televisions and set-top boxes have only one receiving unit. Some VTRs have a function of recording a back program while watching two programs with two receiving units. However, the two receiving units are for selecting and extracting one of the program signals from the transmitted radio waves, and basically have the same function.
Gazette

  In conventional televisions, videos, set-top boxes, etc., even if there are two receiving units, both receiving units are controlled only from the receiving device. That is, it is possible to control only from the receiving device whether the receiving device receives, does not receive, or which channel is selected when receiving. Therefore, the receiving unit cannot be controlled from a broadcasting station on the transmission side. Therefore, even if a data storage unit or the like is provided in the receiving apparatus, data cannot be stored freely from the transmission side. Further, the program sending side cannot select a program displayed on the display or a program stored in the storage device.

  In order to solve this problem, in the present invention, two or more receiving units are provided in a receiving device, and switching of the channel of one receiving device is left to the viewer freely, and the channel of the other receiving device is in principle the channel of the other receiving device. Viewers cannot switch, and control is possible on the side that transmits data such as programs. In addition, the data received by the other receiving unit can be automatically stored, and data for various controls of the receiving device itself, company advertisements, etc. can be stored and used appropriately.

  In the present invention, in addition to the program for viewing, it is possible to receive a signal for controlling the receiving device itself and advertising information of a company. Therefore, the receiving apparatus and the receiving system itself can be controlled from the program sending side. For example, it is possible to display on a display regardless of a program in which a corporate advertisement is viewed.

  FIG. 3 shows an overview of a system including the receiving apparatus 300 of the present invention. Data such as a program is received by the receiving apparatus 300 of the present invention, and a part of the received data is accumulated, sent to the received data processing apparatus 301 to be processed into a signal for display on a display, or audio Or processed into a signal. Then, it is sent to the display device 302 or the like and displayed so that the viewer can view it. The present invention relates to the receiving apparatus 300 portion in the receiving system 303, and more specifically has the functional blocks shown in FIG.

  As shown in FIG. 1, the receiving device 100 of the present invention includes a first receiving unit 101, a second receiving unit 102, a command receiving unit 105, a switching control unit 103, a storage control unit 104, and a data storage unit. 106. The first receiving unit 101 receives the first data, and the second receiving unit 102 receives the second data. The first data is, for example, a movie, and the second data is, for example, an advertisement for a car owned by a hero appearing in the movie. The data storage unit 106 stores data. The data storage unit 106 may be a hard disk, RAM, cache memory, ROM, DVD, FDD, or the like. The command receiving unit 105 receives a command for switching the channel received by the first receiving unit 101. The accumulation control unit 104 accumulates the data received by the second receiving unit 102 in the data accumulation unit 106. These functions function as shown in FIG.

  As shown in FIG. 2, it is assumed that the channel 1 program is received by the first receiving unit. If the viewer wants to change to a channel 2 program on the television 202, the command receiving unit is given a command to switch channels using a remote control device or the like. The command receiving unit is, for example, a part that receives a signal from the remote controller 201. When the remote controller 201 is an infrared remote controller, the command receiving unit is an infrared light receiving unit and a signal processing unit associated therewith. When a command to switch to channel 2 is received by the command receiving unit, the switching command is passed to the switching control unit, and control for switching the channel of the first receiving unit is performed. As a result, the channel 2 program is also displayed on the display device. At this time, the data received by the second receiving unit is stored in the data storage unit 203.

  FIG. 4 shows how the channel of the first receiving unit is switched by the switching control unit. For example, if the first receiving unit 400 can receive data of channels 1 to 3, the receiving device receives only one of the channels. You must select a channel. For this selection, the first receiving unit 400 includes a switching control command acquisition unit 401 and a channel switching unit 402. The switching control command acquisition unit 401 acquires a switching command from the switching control unit, and this switching command Accordingly, the channel switching means 402 switches the channel.

  As used herein, channel switching refers to tuning of a carrier wave that carries an analog terrestrial signal that has been used in conventional television broadcasts, as shown in FIG. For example, it means changing the tuning wave number from f1 hertz to f2 hertz. In addition, switching the URL of a broadcasting station in the case of Internet broadcasting, for example, changing “http://www.abc.co.jp” to “http://www.efg.co.jp” When a plurality of channels are multiplexed and transmitted by TDMA or the like using packet communication or ATM communication, etc., this includes selecting a packet or cell based on management information attached to its header. . For example, when a specific type of packet or cell is selected by an identifier included in the header.

  On the other hand, the second receiving unit receives the second data, and this data is stored in the data storage unit by the storage control unit. For example, as shown in FIG. 6, the data received by the second receiver is a control signal for controlling functions of a receiving device, a received data processing device, a display device, and other devices attached to the system, For example, a control signal for compressing and storing storage medium data, and advertising information for displaying on a display device together with a program and allowing a viewer to view it, for example, an advertising advertisement for a company T car, a receiving device, a received data processing device, A program for causing a display device or the like to execute a specific procedure, for example, a program for executing a word processor function, or a part of the program, such as a dynamic link library, an emergency such as an earthquake or disaster This is a signal for transmitting information that requires information, such as evacuation site information at the time of a disaster.

  These are of the nature of being transmitted in common from the transmitting station to the entire receiving system under the transmitting station by broadcasting. The data received by the second receiving unit may be individual signals such as telephone calls and e-mails performed between the receiving systems. The signal received by the second receiving unit is accumulated in the accumulating unit, so that it can be taken out and used anytime thereafter, and can be used any number of times as long as it is accumulated, not just once.

  For example, urgent signals such as earthquakes and disasters can be stored once and stored even if broadcasting functions such as broadcasting stations are stopped. Also useful for information that needs to be confirmed. Further, since the advertisement information of the company does not change every time it is displayed on the display, it is convenient that once it is stored, it can be taken out from the storage device and displayed on the display at any time thereafter.

  This type of information can be transmitted by including it in the data received by the first receiving unit, received by a single receiving device, and managed by signal processing internally. Therefore, it is inconvenient that it takes time and labor to reconstruct the management signal, advertisement, emergency information, etc. once delivered to the broadcasting station.

  Furthermore, since the control of the first receiving unit is basically left to the viewer, in order to view the content that anyone wants to view such as emergency information, the receiving device is divided into two or more general programs. It is more convenient to control the data separately from the data received. For example, it is convenient that the viewer cannot perform control such as channel switching of the second receiving unit.

  FIG. 7 shows a case where the data received by the second receiving unit 702 is corporate advertisement information. Data 1 (706), which is data received by the first receiving unit 701, is transmitted through the received data processing unit 704 and the display device 705 in the majority of the screen on the display, for example, in an area of about 70 to 90%. The viewer views this. On the other hand, the data 2 (707) received by the second receiving unit 702 is accumulated in the data accumulating unit 703, transferred to the received data processing unit 704, and occupied by the data 1 (706) via the display device 705. Is projected on the rest of the area.

  Since this is advertising information, it is displayed on the display to the extent that it does not interfere with the viewer's viewing of the program. The corporate advertisement information may be displayed on the display at the same time as the data is received by the second receiving unit 702, or may be displayed later after the data is once stored in the data storage unit 703. . Therefore, even when the second receiving unit 702 has not received the advertisement, it can be displayed on the display by extracting the data from the data storage unit 703.

Next, an invention in which the second data receiving unit receives data and a channel switching command will be described. As shown in FIG. 8, the receiving apparatus of the present invention includes a first receiving unit 801, a second receiving unit 802, a switching control unit 803, an accumulation control unit 804, a command receiving unit 805, a data accumulation unit 806, and a second switching control. Part 807. Then, the second receiving unit 802 receives data and a channel switching command. The channel switching command is a command for switching the channel of the second receiving unit 802. The basic functions of the first receiving unit 801, the switching control unit 803, the command receiving unit 805, the accumulation control unit 804, and the data accumulation unit 806 are the same as the functions of the receiving apparatus described first. As described above, the feature of the present invention resides in the second receiving unit 802 and the second switching control unit 807.

The second receiving unit 802 receives data and a channel switching command, and the second switching control unit 807 switches the channel of the second receiving unit 802 based on the channel switching command received by the second receiving unit 802. Take control. The second receiving unit 802 receives a signal from the second switching control unit 807 and performs channel switching by the configuration shown in FIG. As shown in FIG. 9, the second reception unit 900 includes a second switching control command acquisition unit 901 that acquires a switching control command from the second switching control unit, and a switching command from the second switching control command acquisition unit 901. Channel switching means 902 for switching channels based on the above. When channel 1 is selected by the channel switching means 902, the data of channel 1 is stored in the data storage unit 903. When the channel is switched, the data of the switched channel is stored in the data storage unit 903.

This is shown in FIG. When the receiving system including the receiving device is a television, the second receiving unit of the receiving device of the television 1001 originally received the advertisement data of company T and stored it in the data storage unit 1003. When the switching command is received by the second receiving unit of the receiving device of the television 1002, the data is switched to the advertisement channel of N company and the data is received and stored in the data storage unit 1004. During this time, the TV program may be displayed with a program unrelated to the advertisement, or the advertisement advertisement of company T is initially displayed, and the advertisement advertisement of company N is displayed together with the channel switching command. It is good also as processing. The embodiment of the present invention described above shows an example of the present invention and is not intended to limit the scope of rights of the present invention. The scope of rights of the present invention is not limited to these examples, and includes all applicable embodiments.

  Next, the control method for the receiving apparatus of the present invention will be described. As shown in FIG. 11, the present invention first waits until there is an input for reception (step S1101). If there is an input, it is determined whether there is a channel switching command (step S1102). If there is, the channel of the first receiving unit is switched (step S1103), and then it is determined whether data is received by the second receiving unit (step S1104). Step S1105), the process is terminated.

  Further, as shown in FIG. 12, the data received by the second receiving unit may be necessarily stored in the data storage unit. The process shown in FIG. 12 waits until there is an input for reception (step S1201). If there is an input, it is determined whether there is a channel switching command (step S1202). The channel of the receiving unit is switched (step S1203), and then it is determined whether data is received by the second receiving unit (step S1204). If data is received, this is received (step S1205). The received data is stored in the data storage unit (step S1206), and the process is terminated.

  What is shown in FIG. 13 is an explanation when the second receiving unit receives a signal for switching the channel received by the second receiving unit. Wait until there is an input for reception (step S1301). If there is an input, determine whether there is a channel switching command (step S1302). If there is a channel switching command, switch the channel of the first receiving unit. (Step S1303) Next, it is determined whether data is received by the second receiving unit (Step S1304). If data is received, it is received (Step S1305), and the received data is stored in the data storage unit. (Step S1306), and the second receiving unit determines whether or not a channel switching command is received (step S1307). If there is a reception, the channel of the second receiving unit is switched (step S1308). The process is terminated.

  These processes are not necessarily performed in the receiving apparatus and the receiving system, but may be performed in an attached peripheral device or the like. It is convenient to use a recording medium in which a program for performing the processing shown in FIGS. 11 to 13 is recorded so as to be readable by a computer.
