FIG. 1 is a schematic configuration of a television receiver 100 to which an embodiment is applied. The television receiver 100 includes a terrestrial digital tuner 101 for receiving a terrestrial digital television broadcast, a BS tuner 102 for receiving a BS digital broadcast or an advanced BS digital broadcast, a broadband CS digital broadcast or an advanced broadband CS digital broadcast. When the terrestrial digital television broadcast is received, the terrestrial digital tuner 101 receives a terrestrial digital television broadcast, and the stream of a channel selected from the received broadcast signals is a 2K decoder 121. Entered in.

  When BS digital broadcasting is received, the broadcast signal is received by the BS tuner 102, and the stream of the channel selected from the received broadcast signals is input to the 2K decoder 131, 4K decoder 132, or 8K decoder 133. To be done. Regarding the 8K decoder 133, there may be a television receiver in which this is not installed.

  When a broadband CS digital broadcast is received, the broadcast signal is received by the CS tuner 103, and the stream of the channel selected from the received signals is input to the 2K decoder 141 or 4K decoder 142.

  The selector 150 displays the video or audio decoded output of any of the 2K decoder 121, 2K decoder 131, 4K decoder 132, 8K decoder 133, 2K decoder 141, or 4K decoder 142 on the display 172a or 172b or the speaker 174. Switch the path to output from. The decoded output selected by the selector 150 is input to the content processing unit (including the video/audio/caption data processing unit) 160.

  When processing content such as video signals, audio signals, and subtitle data, the content processing unit 160 performs color adjustment, brightness adjustment, volume adjustment, subtitle display on/off control, and the like.

  The video signal output from the content processing unit 160 is subjected to gamma correction suitable for the function and size of the display 172a having, for example, 8K display capability in the display signal output unit 171, and is output to the display 172a. The audio signal output from the content processing unit 160 is converted into an audio channel according to the audio system in the audio signal output unit 173 and output to the speaker 174.

  Depending on the receiving device (for example, a device that does not include the 8K decoder 133), there is a case where the display device 172b has the ability to display up to 4K pixels and is equipped with the ability adapted to this ability.

  The integrated control unit 180 includes a network interface 181, a mobile terminal cooperation interface 182, a remote controller interface 183, and the like. In the figure, the interface is shown as I/F.

  The network interface 181 is used, for example, when receiving network service information, a network distribution moving image, etc. via the Internet. The mobile terminal cooperation interface 182 is used when communicating with a mobile terminal. The remote controller interface 183 is used to receive various commands from the remote controller 200.

  In response to the operation of the remote controller 200, the integrated control unit 180 controls the tuners, the decoders, the selector 150, and the like described above, and executes the channel selection determination of the channel to be viewed.

  As shown in FIG. 2B, the broadcasting station multiplexes application control information/service data/control data in addition to contents such as a video stream, an audio stream, and a data broadcasting stream via a broadcast wave transmission path 400. Will be transmitted.

  FIG. 2A schematically shows the main configuration of the broadcasting station 300. The broadcasting station 300 generates attached data for generating control data and service data such as a video encoder 301, an audio encoder 302, a caption encoder 303, other transmission control information, and application control information for controlling the application 215 operating on the receiver side. The unit 304 is provided. Further, the broadcasting station 300 cooperates with the broadcasting station server 311, the first security function 312, and the transmitting/receiving unit 313.

  The transmission control signal generated by the attached data generation unit 304 includes various information and programs called program specific information (PSI: Program Specific Information) and program arrangement information (SI: Service Information) that are defined for program selection. It contains various information specified for the convenience of selection.

  The outputs of the video encoder 301, the audio encoder 302, the subtitle encoder 303, and the attached data generation unit 304 are streamed, and these streams are multiplexed by the multiplexing unit 305. The multiplexed stream (video stream, audio stream, data broadcast stream, application control information/service data/control data, etc.) is sent to the transmitter 306 as a transport stream, and is transmitted from the antenna by broadcast waves.

  The codec type of the video encoder 301 is MPEG-2, H.264. H.264 (AVC: Advance Video Coding), H.264. Any of H.265 (HEVC: High Efficiency Video Coding) may be used.

  FIG. 2B shows a broadcast wave transmission path 400 broadcast from the broadcasting station 300. As shown in FIG. 2B, in the broadcast wave transmission line 400, application control information/service data/control data are multiplexed in addition to contents such as a video stream, an audio stream, and a data broadcast stream.

  FIG. 2C is a diagram showing a configuration example in the integrated control unit 180 of the receiving device.

  The various control units are not limited to the classification shown in the figure, and various control units can be added or removed depending on the installed application. The illustrated example will be described. The control unit 180a functions as, for example, a processing capacity information unit of the television receiver. The control unit 180a holds processing capability information of a tuner and a decoder mounted on the television receiver. The control unit 180a also holds display capability information of the connected display devices 172a and/or 172b. The display capability information of the display device includes, for example, information including at least the number of pixels 2 which can be displayed by the display device, but may be other setting information. The display capability information of the display devices 172a and/or 172b may be collected when mutual authentication communication is performed when these display devices are connected to the television receiver.

  As described in Non-Patent Document 4 and Non-Patent Document 5, the television receiver 100 searches all receivable channels (services) at the receiving point as an initial setting, and services based on the service identification (service_id). It is necessary to create a list (receivable frequency list).

  The control unit 180b functions as a service identification/service format type determination unit. The control unit 180b scans broadcast waves in a receivable range at the time of initial setting, for example, and extracts a service identification and a service type type (service_type) that are included in an NIT (Network Information Table) as transmission control information and are transmitted. However, it has a function of storing the value of the service identification and the value of the service type classification, and can also store the determination result of the receivable service identification. Further, the control unit 180b extracts the organization channel name and the business operator name arranged in the service descriptor (Service descriptor) included in the SDT (Service Description Table) and transmitted as the transmission control information, and the organization channel name. It also has the function of saving the name of the business operator.

  Here, the service is an organization channel, which is defined in Non-Patent Document 1 as "a series of programs that can be broadcast by a broadcaster as part of a schedule". The service is defined at the stage where the service identification arranged in the service list descriptor in NIT (Network Information Table) which is one of the transmission control information is described.

  The service identification is an ID that is uniquely assigned to each channel in each broadcast wave type.

  The control unit 180c has a function as a service list creation unit. The control unit 180c can create and hold a service list based on the service identification and the service format type determined by the control unit 180b. The control unit 180c can also add the organization channel name and the business operator name arranged in the service descriptor to the service list.

  The control unit 180d functions as a remote controller input determination unit that determines an operation input given from the remote controller 200. The operation input from the remote controller 200 includes power on/off input, broadcast wave type selection input, channel selection input (12 position key input, up/down channel selection key input), image quality adjustment input, volume adjustment input, etc. There is. The control unit 180d outputs a command to the operation target location according to the operation input. When detecting the broadcast type selection input, the control unit 180d controls the tuner control unit 180s, the decoder control unit 180t, the content processing control unit 180u, each output control unit 180v, and the like. In addition to the remote controller 200, the device for giving an operation input may be a portable terminal or an operation button provided in the housing of the receiving device.

  The control unit 180e functions as a service list selection unit. The control unit 180e can operate in cooperation with the control unit 180c, the control unit 180d, and the like. For example, when the broadcast type selection input is detected, the channel corresponding to the detected broadcast type is set as the used channel from the plurality of service lists of the control unit 180c. When the channel selection (service selection) input is detected, the information (channel selection data) of the channel corresponding to the selected channel (service) is output from the service list to perform tuner control.

  Further, the integrated control unit 180 further includes a service data analysis unit 180w that receives and analyzes service data, control data, and the like different from the video/audio content.

  Further explanation will be given. The tuner control unit 180s operates for tuner selection and switching, and channel selection and switching. The decoder control unit 180t operates to select and switch various decoders. The content processing control unit 180u controls the operation mode of the content processing unit 160 (color adjustment, brightness adjustment, volume adjustment, subtitle display on/off control, etc.). Each output control unit 180v selects the output form of the audio signal (stereo output, monaural output, 5-channel output, etc.) and the output form of the video signal (8K, 4K, frame frequency, etc.). Therefore, each output control unit 180v uses the type information of the audio system ((stereo, monaural, the number of channels, etc.), the display capability information of the connected display ((the information of the number of pixels such as 8K, 4K, and the adaptive frame frequency Information).

  FIG. 3A shows the overall structure of the service list descriptor described in Non-Patent Document 1. A service identification (service_id) 301 and a service type (service_type) 302 are arranged in this service list descriptor. The service identification identifies a so-called channel, and the service type represents a service format type (broadcast type) to which the channel belongs. By monitoring this service list descriptor, it is possible to determine which channel of what broadcast type is currently being received.

  FIG. 3B shows the bit assignment of the service format type arranged in the service list descriptor.

  Here, the digital TV service of service type type=0x01 is a service (channel) whose main purpose is to watch a video stream, and a channel watched by a general user corresponds to this service.

FIG. 4 shows the overall structure of the service descriptor described in Non-Patent Document 1. The N character char shown at 401 in the figure represents the business name. Also, the N character char indicated by 402 in the figure represents the service name (channel name). In FIG. 5, the service list created by the conventional television receiver A by the above-mentioned process is It is an example of the display content when displaying on the display 172a or the display 172b.

  FIG. 6 is an example of a processing flow when the conventional television receiver A creates a service list (receivable frequency list) based on service identification.

  Note that the description of the processing flow in FIG. 6 will be made assuming that the broadcast wave type is BS digital, but the same processing flow is used for other examples of existing broadcast wave types in broadcasting using satellites, such as broadband CS digital. Become. Further, the conventional television receiver A in the explanation of the processing flow in FIG. 6 can receive the broadcast wave types of terrestrial digital television, BS digital, and wideband CS digital. Further, it is assumed that the conventional television receiver A can only recognize the bit assignment of the service identifier shown in FIG. 3B. The television receiver A sequentially creates a service list for all broadcast wave types that can be received.

  When the television receiver A starts the channel search process (service list creation process) (S600), the set frequency is set to the lower limit of the prescribed frequency group (S601). The television receiver A detects NIT (Network Information Table) at the set frequency (S602).

  When the television receiver A recognizes the NIT at the set frequency (Yes in S602), the television receiver A extracts the service list descriptor from the NIT (S603). The television receiver A extracts the service identification from the extracted service descriptor (S604), and further extracts the service format type (S605).

  The television receiver A extracts the service format type (S605), and determines the value (S606).

  As a result of the determination, when the value of the service format type is “digital TV service=0x01” (S606 Yes), the television receiver A adds the service identification extracted in S605 to the service list (S607). The television receiver A confirms whether the set frequency has reached the upper limit of the specified frequency group (S608).

  When it is determined that the upper limit has not been reached (No in S608), the television receiver A updates the frequency set in the tuner (S609). After that, the television receiver A repeats the processing from S602 to S609 until the frequency set in the tuner reaches the upper limit of the specified frequency group.

  As a result of the determination, when it is determined that the upper limit is reached (S608 Yes), the channel search processing (service list creation processing) is ended (S610).

  In the process of repeating the processing of S603 to S609, the service identification extracted in S605 is added to the channel list (S607).

  Further, the television receiver A extracts the SDT (Service Description Table) from the broadcast waves sent for each service (channel) recognized by creating the service list, and the service descriptor included in the SDT (Service Description Table). This information can be added to the service list by extracting the organization channel name and the business operator name placed in the (Service descriptor) (see Fig. 4).

  FIG. 7 is an example of information stored in the service list created by the processing shown in FIG. 6 by the television receiver A. FIG. 7 is a service list created by the television receiver A for BS digital broadcasting.

  As mentioned earlier, when new broadcast wave types (advanced BS digital, advanced broadband CS digital) are added in the future, the ability of the receiver to receive the broadcast wave and the ability of the display to display the received broadcast wave There may be various combinations of.

  The combination of the reception capability of the broadcast wave type of the receiver and the display capability of the display is, for example, a combination in which the receiver has the ability to receive 8K image quality broadcast and the display has the ability to display up to 4K image quality broadcast Can be considered. Further, for example, a combination in which the receiver has the ability to receive advanced BS digital broadcasting and advanced broadband CS digital broadcasting and the display has the ability to display up to 2K image quality broadcasting is also conceivable. It is also conceivable that a plurality of display devices having different display capabilities are connected to one receiver.

  FIG. 8 shows an example of a combination of the types of broadcast waves receivable by the receiver and the display capability (number of pixels) of the display.

  As described above, in various combinations of the receivable broadcast wave type and the display capability of the display, it is desirable that the service (channel) can be selected and displayed according to the display capability of the display.

  Therefore, as one embodiment, the television receiver 100 can select a service (channel) according to the display capability of the display 172 based on the service list created for the receivable broadcast wave types. In order to do so, the service format type shown in FIG. 3B is expanded and used.

  FIG. 9 shows an example extended to the bit assignment of the service format type shown in FIG. 3B.

  Reference numeral 902 indicates an extended bit assignment 0xAE and an ultra high definition 4KTV service which is the meaning of the value. The ultra-high-definition 4KTV service means a service type in which the broadcast wave type is advanced BS digital or advanced broadband CS digital, and the number of pixels is 4K image quality. The 4K dedicated service may use the bit assignment 0xAD.

  Similarly, reference numeral 903 indicates an extended bit assignment 0xAF and its meaning, an ultra high definition 8KTV service. The ultra high definition 8KTV service means a service type in which the broadcast wave type is advanced BS digital or advanced broadband CS digital, and the number of pixels is 8K image quality.

  With the addition of 902 and 903, the conventional bit assignment 0x01 of 901 is changed to the service type in the case of the broadcast wave type of terrestrial digital television, BS digital, and wideband CS digital.

  FIG. 10A illustrates a service list based on the service identification by the television receiver 100 according to an embodiment when the NIT in which the service list descriptor having the extended service format type illustrated in FIG. 9 is arranged is sent. It is a figure showing an example of a processing flow which creates a (receivable frequency list). It should be noted that the television receiver 100 in the description of the processing flow in FIG. 10A can receive all broadcast wave types of terrestrial digital television, BS digital, broadband CS digital, advanced BS digital, and advanced broadband CS digital. In the processing flow of FIG. 10A, the broadcast wave type is described as advanced BS digital, but the same processing flow is used for other broadcast wave types such as advanced broadband CS digital.

  When the service identification/service format type determination unit 180b starts the channel search process (S1000), the circular polarization setting of the BS digital tuner is set to right-hand circular polarization (S1001), and the frequency to be set is the specified frequency. The lower limit of the group is set (S1002). The service identification/service format type determination unit 180b detects an NIT (Network Information Table) at the set frequency (S1003).

  When the service identification/service format type determination unit 180b recognizes the NIT in the set frequency (S1003 Yes), the service list descriptor is extracted from the NIT (S1004). The service identification/service format type determination unit 180b extracts the service identification from the extracted service descriptor (S1005), and further extracts the service format type (S1006).

  The service identification/service format type determination unit 180b extracts the service format type (S1006) and then determines the value (S1007).

  As a result of the determination, when the value of the service format type is “digital TV service=0x01” (S1007 Yes), the service identification/service format type determination unit 180b adds the service identification extracted in S1005 to the service list. By instructing the list creation unit 180c, the service list creation unit 180c adds the service identification extracted in S1005 to the service list (S1008). The service identification/service format type determination unit 180b confirms whether the set frequency has reached the upper limit of the specified frequency group (S1009).

  If it is determined that the upper limit has not been reached (No in S1009), the service identification/service format type determination unit 180b updates the frequency set in the tuner (S1012). Thereafter, the service identification/service format type determination unit 180b repeats the processing of S1003 to S1009 until the frequency set in the tuner reaches the upper limit of the specified frequency group.

  When it is determined that the upper limit is reached (Yes in S1009), the service identification/service format type determination unit 180b sets the circular polarization setting of the tuner to the left-hand circular polarization (S1013) and sets it to the tuner. The processes of S1003 to S1009 are repeated until the frequency reaches the upper limit of the specified frequency group.

  In the process of repeating the processing of S1003 to S1009, the service identification/service format type determination unit 180b instructs the service list creation unit 180c to add the service identification extracted in S1005 to the service list creation unit 180c. 180c adds the extracted service identification to the channel list (S1008).

  Furthermore, the service identification/service format type determination unit 180b extracts an SDT (Service Description Table) from the broadcast waves transmitted for each service (channel) recognized by creating the service list, and includes it in the extracted SDT. It is possible to add these pieces of information to the service list by extracting the organization channel name and the business operator name arranged in the service descriptor (see FIG. 4) that is stored. FIG. 11A is an example of a service list when the television receiver 100 creates a service list for the broadcast wave types BS digital and advanced BS digital by the processing shown in FIG. 10A. FIG. 11A(A) is a service list created by the television receiver 100 for BS digital broadcasting. 11A(B) is a service list created by the television receiver 100 for advanced BS digital broadcasting. The service list includes service identification, service type classification, organization channel name, and business name. Here, the content of the service format type includes content according to the extension of the bit assignment of the service format type shown in FIG. In the example of FIG. 11A(B), when the service identification is 824, 826, and 827, the service type classification is the ultra-high definition 4KTV service, and when the service type is 25, the service type classification is the ultra-high definition 8KTV service. ..

  FIG. 10B illustrates a service list based on the service identification by the television receiver 100 according to an embodiment when the NIT in which the service list descriptor having the extended service format type illustrated in FIG. 9 is arranged is sent. It is a figure which shows the other example of the processing flow which produces|generates (list of receivable frequencies). However, the television receiver 100 in the description of the processing flow of FIG. 10B is terrestrial digital television, BS digital, wideband CS digital, advanced BS digital (however, 4K image quality broadcasting only) Receivable. In the processing flow of FIG. 10B, the broadcast wave type is described as advanced BS digital, but the same processing flow is used for other broadcast wave types, for example, advanced broadband CS digital.

  The process flow of FIG. 10B is the same as the process flow of FIG. 10A except for S1027 which is a process corresponding to S1007 in the process flow of FIG. 10A. The television receiver 100 extracts the service format type (S1026), and determines the value (S1027).

  If the result of determination is that the value of the service format type is "digital TV service (0x01)" or "ultra high definition 4KTV service (0xAE)" (S1027 Yes), the television receiver 100 identifies the service identified in S1025. Is added to the service list (S1028).

  FIG. 11B is an example of a service list when the television receiver 100 creates a service list for the broadcast wave types BS digital and advanced BS digital by the processing shown in FIG. 10B. FIG. 11B(A) is a service list created by the television receiver 100 for BS digital broadcasting. Further, FIG. 11B(B) is a service list created by the television receiver 100 for advanced BS digital broadcasting. The service list includes service identification, service format type, organization channel name, and business name.

  Unlike the service list shown in FIG. 11A, the service list shown in FIG. 11B(B) does not include the service whose service format type is the ultra high definition 8KTV service. That is, the television receiver 100, which has created the service list by the processing shown in FIGS. 10A and 10B, selects one of the services (channels) broadcast in advanced BS digital according to its reception capability from FIG. As shown in B) and FIG. 11B(B), it is possible to create a service list by distinguishing between the service (channel) of 4K image quality broadcasting and the service (channel) of 8K image quality broadcasting.

  FIG. 12A shows a recorder 1201 according to an embodiment capable of receiving all terrestrial digital television, BS digital, broadband CS digital, advanced BS digital, and advanced broadband CS digital as broadcast wave types, and a display device. It is the figure which showed the form of connection with the display device from which the number of pixels differs. To this recorder 1201, it is possible to arbitrarily connect a display device 1202 having a display pixel number of 8K, a display device 1203 having a display pixel number of 4K, and a display device 1204 having a display pixel number of 2K. Further, the recorder 1201 has a service list-01 created for terrestrial digital television broadcasting shown in FIG. 12B(A), a service list-02 created for BS digital broadcasting shown in FIG. 12B(B), and FIG. 12B( It is assumed that the service list -03 is prepared for the advanced BS digital broadcasting shown in C). The service list-01, the service list-02, and the service list-03 are collectively referred to as a service list 0.

  When a plurality of display devices having different display capacities are connected to one recorder in this way, the processing capacity information unit 180a of the recorder 1201 indicates that the connected 8K display devices 1202, 4K display devices 1203, 2K are connected. From the created service list-01, service list-02, and service list-03 so that the display capability of the display device 1204 can be identified and the service (channel) can be output to each display device, the 8K display device 1202 is displayed. In order to display a video signal on the screen, a service list-11 to a service list-11 is created for terrestrial digital television broadcasting, and a service list-12 to a service list-12 is created for BS digital broadcasting. For advanced BS digital broadcasting, the service list creation unit 180c may be instructed to create the service list 13 from the service list-03. Here, the service list-11, the service list-12, and the service list-13 are collectively referred to as a service list 1.

  Similarly, the processing capacity information unit 180a of the recorder 1201 uses the created service list-01, service list-02, and service list-03 to display a video signal on the 4K display unit 1203, and then performs terrestrial digital television broadcasting. For the BS digital broadcasting, the service list-21 is created from the service list-01, the service list-22 is created from the service list-02, and the advanced BS digital broadcasting is served from the service list-03. The service list creation unit 180c may be instructed to create the list 23. Here, the service list-21, the service list-22, and the service list-23 are collectively referred to as a service list 2.

  Similarly, the processing capability information unit 180a of the recorder 1201 uses the created service list-01, service list-02, and service list-03 to display terrestrial digital television broadcasting in order to display a video signal on the 2K display 1204. For the BS digital broadcasting, the service list 31 is created from the service list-01, the service list-02 is created from the service list-02, and the advanced BS digital broadcasting is served from the service list-03. The service list creation unit 180c may be instructed to create the list 33. Here, the service list-31, the service list-32, and the service list-33 are collectively referred to as a service list 3.

  In the memory 1210 of FIG. 12A, an area 1210-1 for storing the contents of the service list-1 displayed for 8K correspondence, an area 1210-2 for storing the contents of the service list-2 displayed for 4K correspondence, 2K correspondence There is an area 1210-3 for storing the contents of the service list-3 displayed for the user. The recorder 1201 displays the service list-1 created from the service list-0 for 8K compatibility in the area 1210-1 and the service list-2 displayed for 4K compatibility in the area 1210-2 for 2K compatibility. The service list-3 to be executed is saved in the area 1210-3.

  12C to 12E show examples of service lists created by the television receiver 100 for the display device 1202, the display device 1203, and the display device 1204. 12C shows an example of service list-1 displayed for the display device 1202, FIG. 12D shows an example of service list-2 displayed for the display device 1203, and FIG. 12E shows an example of service list-3 displayed for the display device 1204. Is. The service list of the terrestrial digital television broadcast and the service list of the BS digital broadcast whose broadcast wave types are common to all of the displays 1202 to 1204, but the service list of the advanced BS digital broadcast has its contents depending on the display capability of the display. Indicate that they are different.

  As described above, the television receiver 100 can also provide the service list according to the display capability of the display device by using the extended service format type as shown in FIG.

  The example of the recorder 1201 described above creates a service list for each display device based on the service list created for the receivable broadcast wave type, in accordance with the display capabilities of a plurality of connected display devices. However, instead of creating a service list for the receivable broadcast wave types, the recorder 1201 creates a service list for the receivable broadcast wave types based on the display capability of the connected display unit. You may.

  For example, it is assumed that the recorder 1201 shown in FIG. 12A is connected only to the 4K compatible display 1203 and the 2K compatible display 1204. The recorder 1201 can receive all broadcast wave types such as terrestrial digital television, BS digital, wideband CS digital, advanced BS digital, and advanced wideband CS digital, but of the connected display device included in the control unit a. Using the display capability and the received service format type, only the service list displayed for the 4K compatible display 1203 and the service list displayed for the 2K compatible display 1204 may be created. In this case, the service list created for the 4K compatible display device 1203 has the content shown in FIG. 12D, and the service list created for the 2K compatible display device 1204 has the content shown in FIG. 12E.

  In addition, the recorder 1201 matches the display capability of the connected display device (if it says down conversion? Is it a display capability instead of "regardless of display capability"? In addition, all broadcast wave types will be down-converted and displayed), and it may have a control function that allows down conversion so that receivable broadcast wave type programs can be displayed on the display. The extension example for the bit assignment of the service format type shown in FIG. 3B is not limited to the example of FIG.

  13A and 13B show another example of extension to the bit assignment of the service format type shown in FIG. 3B.

  Reference numeral 1302 in FIG. 13A indicates a bit-assignment 0xAD and an ultra-high-definition 4K dedicated TV service, which means the value thereof. However, unlike the ultra-high definition 4K dedicated TV service of FIG. 3B, the ultra-high-definition 4K dedicated TV service of FIG. 13A means a service type that includes advanced BS digital and advanced broadband CS digital. If you are.

  FIG. 13B is an example in which the service (channel) of 8K image quality broadcasting in which the broadcast wave type is advanced BS digital is assigned as the bit assignment 0xAF of 1305 with respect to the case of FIG. 13A. The ultra-high-definition 4K dedicated TV service of FIG. 13B means a service type in which only 4K image quality broadcasting is performed among advanced BS digital and advanced broadband CS digital, and the ultra-high-definition 8KTV service is broadcast wave type. The type means the service type of advanced BS digital (8K image quality broadcasting service (channel)).

  The buttons appearing in the table are a button 202 labeled as terrestrial, a button 203 labeled as BS, a button 204 labeled as CS, and a button 205 labeled as altitude. However, the button 231 is usually capped and may not be visible. The button 231 is used, for example, for a so-called 8K television device capable of receiving 8KBS, and can be used when the 8K television device is newly purchased.

  FIG. 21 shows a simplified basic operation example of the television receiver 100 operated by the remote controller 200 described above. The integrated control unit 180 manages the program that realizes this operation.

  When a command is received from the remote controller (SA1), it is determined whether the command is a program (channel) selection command (SA2). When this command is present, it is determined whether or not there is a program corresponding to this command (SA3). This judgment is made by checking the EPG or other service information.

  As a result of this check, if the program does not exist (reception channel is not set) or is in the dormant state, a message is displayed indicating that the receive channel is not set or is in the dormant state, and the process ends. (SA4, SA13).

  As a result of the check (SA3), if the program exists, the program (channel) is switched (SA5), and the process ends (SA13).

  When it is determined in the previous step SA2 that the received command is not the channel selection command, it is determined whether or not it is a command for selecting the broadcast wave type (2 KBS, 2 KBS, 4 KBS, 8 KBS, 4 KBS, etc.) ( SA6). If the command is a broadcast wave type selection command, it is determined whether the service is being performed (SA7).

  Here, as a result of this check, if the broadcast wave type does not exist or is in the dormant state, a message indicating that the broadcast wave type is dormant is displayed and the process ends (SA8, SA13). As a result of the check (SA7), if the broadcast wave type is present, switching to receive the broadcast wave type is performed (SA9), and the process ends (SA13).

  When it is determined in the command determination in step SA6 that the command is not the broadcast wave type selection command, another command is determined (SA11), a process based on the determined command is performed (SA12), and the process is terminated (SA13).

  Although various embodiments of the method and means for selecting a broadcast wave type and the method and means for channel selection described above have been described, each of these embodiments is not independent and is implemented by combining a plurality of embodiments. Of course, it may be done.

  There are many types of broadcast wave types as described above. However, not all of these broadcast wave types are constantly broadcast. In many channels, there are cases where transmission is executed (time zone) and cases where transmission is not executed (time zone).

  In order to compensate for the operation of the above-described receiving device, the broadcasting station transmits service information indicating whether or not the broadcast wave type is currently suspended. Also, the selected channel is transmitting service information indicating whether or not the channel is currently idle.

  As the receiving device, a means for referring to service type information in response to a reception command for instructing reception of an advanced broadcast wave type (advanced BS and/or advanced CS, 8 KBS, etc.), and as a result of the reference, the selection When the instructed advanced broadcasting wave type is in a broadcasting suspension, an output means for outputting a message that the broadcasting is in suspension is provided. The message also includes the case where the broadcast time has ended.

  The receiving device further includes means for referencing channel information of advanced broadcast wave type in response to a channel selection command input during reception of advanced broadcast wave type (advanced BS and/or advanced CS, 8 KBS, etc.). As a result of the reference, when the channel instructed to be selected does not exist, an output means for outputting a message that the channel does not exist is provided. Further, depending on the radio wave condition, the channel instructed to select may not be received at a sufficient level. In this case, a message indicating that the channel cannot be received can be output.

  The broadcasting station needs to transmit information on advanced broadcast wave types (advanced BS and/or advanced CS, 8 KBS) and information on channels of advanced broadcast wave types. However, with respect to the broadcasting station, not all broadcasting stations need to transmit such information, and one of the broadcasting stations may representatively transmit as comprehensive service information. In this case, each receiving device should receive the comprehensive service information periodically or when the reception of the broadcast wave type is switched to the reception of another broadcast wave type on a regular basis.
