Description

  The present invention relates to a technology of an apparatus for receiving terrestrial digital broadcast or terrestrial analog broadcast.

  In order to select a channel that the user wants to see in the video receiving apparatus, the frequency band of each receivable broadcast wave must be associated with an identifier included in the video receiving apparatus. . The operation in which the user selects a channel is nothing but the operation in which the user selects one identifier and receives a broadcast wave in the frequency band associated with the identifier. In addition, since the frequency band of receivable broadcast waves is different in each region, when a video reception device is first installed, the association between the receivable frequency band and the identifier provided by the video reception device, that is, channel setting Is required.

  Currently, there are terrestrial analog signals, terrestrial digital signals, BS digital signals, CS digital signals and the like as receivable broadcast waves. For the BS digital signal and the CS digital signal, channel information is included in the signal itself, so channel setting is not necessary, but channel setting is necessary for the terrestrial analog signal and the terrestrial digital signal. However, the channel setting method is complicated and difficult to understand for the current multi-channel. Furthermore, channel setting is usually left to the user. For this reason, it is a problem how to make it possible for a user to set a channel with a small amount of work, which is easy for the user to understand.

Therefore, in Patent Document 1, in order to associate a channel being received with an identifier included in the video reception device, the button pressing time of an input device such as a remote controller is set to a predetermined second or more in a state where the identifier for setting the channel is selected. A method of changing the channel by pressing the button is disclosed. In Patent Document 1, a confirmation screen is displayed when changing the channel setting so that the user does not change the channel setting due to an erroneous key operation. FIG. 13 shows an example of the processing flow of the channel setting method in the prior art. In the prior art, a setting menu is displayed (S1301), and a search is performed by selecting a frequency band search start button from the displayed setting menu (S1302). When the search is completed (S1303), the search result is displayed as a predetermined result. The identifier is assigned (S1304). At this time, before storing the assignment result in the nonvolatile memory or the like (S1306), a screen “Do you want to register?” As shown in FIG. 14 is displayed (S1305).

  Embodiment 1 (Concept of Embodiment 1) FIG. 1 is a diagram for explaining an example of a video receiving apparatus of the present embodiment. Hereinafter, specific processing for setting a frequency band will be described while describing the configuration of the video reception device of the present embodiment.

  (Configuration of Embodiment 1) FIG. 1 is a diagram showing an example of a functional block diagram of a video receiving apparatus of this embodiment. As shown in FIG. 1, the video receiver (0100) of this embodiment includes a “setting menu display unit” (0101), a “frequency band search unit” (0102), and a “receivable frequency band allocation unit”. (0103) and “storage unit” (0104).

  (Description of Configuration of Embodiment 1) “Setting menu display unit” (0101) displays a setting menu. The setting menu display unit may be anything that can display the setting menu, such as a cathode ray tube display, a liquid crystal display, or a plasma display. “Setting menu” includes items prepared for frequency band search, etc., and the user selects these items displayed on the setting menu display section to search for frequency bands and images. Various settings of the receiving device can be made. When performing a frequency band search, if the video receiving apparatus can receive a plurality of broadcast waves, the broadcast wave frequency band search to be performed is selected from the items. As types of broadcast waves, for example, a terrestrial analog signal, a terrestrial digital signal, a BS digital signal, a CS digital signal, and the like can be considered. When there are a plurality of frequency band search methods for one broadcast wave, the frequency band search method to be used for selection is selected. The frequency band search method includes, for example, a method of automatically and sequentially searching for frequency bands that can be received by the video receiving device, and a method of specifying a region by a region number and searching for a frequency band corresponding to the region. Another possible method is to search the frequency band individually by manually checking the frequency of the frequency band to be received. In the setting menu display unit, in order to perform various settings for frequency band search by combining a plurality of items, it is necessary to display a setting menu combining a plurality of items.

  The “frequency band search unit” (0102) searches for a receivable frequency band in accordance with a predetermined search rule in accordance with the selection of the setting menu on the setting menu display unit. “According to the selection of the setting menu” means that a search is performed according to the type of receivable broadcast wave and the frequency band search method. The “predetermined search rule” is a rule for searching for a frequency band determined according to the selection of the setting menu on the menu display unit. For example, in the selection of the setting menu, when a broadcast wave for searching for a frequency band is selected as a terrestrial analog signal, and a search method for automatically searching for a frequency band that can be received by the video receiving device is selected, video reception is performed. The device sequentially and automatically searches for a frequency band in which terrestrial analog signals can be received. “Searching for a receivable frequency band” refers to measuring the frequency intensity of a broadcast wave received from a specific frequency band and detecting a frequency band having a frequency intensity equal to or higher than a certain value as a receivable frequency band. .

  “Receivable frequency band allocating unit” (0103) is a function of allocating a frequency band searched for as receivable by the frequency band searching unit to a predetermined identifier used for a user to select a channel. Have The “identifier” is provided in the video reception device, and the frequency band assigned to the identifier is selected by selecting the identifier. The identifier can be selected by the user using the remote control of the video reception device. For example, the identifier is represented by an identifier number from 1 to 12, and the user selects an identifier number by selecting one of the buttons from 1 to 12 provided on the remote controller or the like. The assigned frequency band is selected. “Assign to a predetermined identifier” means that the frequency band searched as receivable by the frequency band search unit as shown in FIG. 16 is associated with the identifier using a table or the like, and is volatile Temporary storage in a memory or the like. As an allocation method, for example, as described above, when the video reception device has an identifier number of 1 to 12, as shown in FIG. As shown in FIG. 16 (b), when the channel number of the frequency band matches the identifier number, the frequency band is preferentially allocated to the identifier, and the identifier that has not been allocated is still allocated. A method of allocating in order from the lowest frequency band among the frequency bands not performed is considered.

  The “storage unit” (0104) is a deterministic assignment result without performing a display for confirming whether or not the assignment result is definitely stored in response to the completion of the search based on the search rule. It has a function to memorize. “Completion of search” refers to a case where the search is completed normally. That is, if the search is terminated halfway, the search is not completed. The case where the search is normally completed means a state after the frequency band search unit searches all the receivable frequency bands and before storing the allocation result in the storage unit. “Determining the allocation result deterministically” means that the identifier and the frequency band allocation result temporarily stored in the volatile memory or the like by the receivable frequency band allocating unit are turned off when the power of the nonvolatile memory or the like is turned off. Is also stored in a storage area that is not erased. After the assignment result is definitely stored, when the user selects a channel, for example, the frequency band is selected by selecting an identifier using the table of FIG. 16A stored in the nonvolatile memory. Will be able to do. “Display for confirming whether assignment result is memorized deterministically” is displayed after a search is completed in the frequency band search part, and a warning screen such as “Do you want to register?” Say. In the prior art, processing is performed according to the flowchart shown in FIG. 13, and as shown in FIG. 14, after completion of the search, a screen such as “Do you want to register?” Is displayed and the assignment result is definitely stored. The final decision on whether or not to do so was made by the user. However, the storage unit of the video receiving apparatus according to the present embodiment stores the assignment result definitely without displaying this “Do you want to register?”.

  (Processing diagram common to all embodiments) FIG. 15 shows a specific processing diagram of the video receiving apparatus of the first embodiment. In the video receiving apparatus in FIG. 15, the user selects a setting menu displayed on the OSD (On Screen Display) processing unit (1502) by a key operation from the key input unit (1501), and performs an operation to perform a frequency band search. The instruction is accepted, and the accepted operation instruction is passed to the control unit (1503). In response to the received operation instruction, the control unit causes the receiving unit (1504) to receive a broadcast wave to search for a frequency band. The receiving unit measures the frequency intensity of the received broadcast wave, and transmits a frequency band having a frequency intensity equal to or higher than a certain level to the control unit. The control unit determines that a frequency band having a frequency intensity equal to or higher than a certain level is a receivable frequency band, and assigns the frequency band to a predetermined identifier. The storage unit (1508) stores the identifier and the assigned frequency band in association with each other. Thereafter, the user can receive a broadcast wave in the frequency band associated with the identifier by inputting a predetermined identifier at the key input unit. The received broadcast wave is converted into a video signal or an audio signal by the signal processing unit (1505), the converted video signal is monitored by the image monitor unit (1506), and the audio signal is monitored by the audio monitor unit (1507). Output from the display or speakers. The control unit controls these processing units in an integrated manner. In the correspondence between the functional block diagram shown in FIG. 1 and the processing diagram shown in FIG. 15, the setting menu display unit (0101) corresponds to the OSD processing unit (1502), and the frequency band search unit (0102) corresponds to the receiving unit (1504). The receivable frequency band allocating unit (0103) corresponds to the control unit (1502), and the storage unit (0104) corresponds to the storage unit (1508). The video receiving apparatus according to the present embodiment is realized by being executed in each of these processing units. The video receiving apparatuses according to the following second to fourth embodiments are also represented by the same processing diagram.

  (Processing Flow of Embodiment 1) FIG. 2 is a flowchart showing an example of the processing flow of this embodiment. In the video receiver according to the present embodiment, first, a setting menu is displayed (S0201, setting menu display step). Next, in accordance with the selection of the setting menu displayed in the setting menu display step, a receivable frequency band is searched according to a predetermined search rule (S0202, frequency band searching step). When the search is completed (S0203), the frequency band searched as receivable in the frequency band search step is assigned to a predetermined identifier used by the user to select a channel (S0204, reception). Possible frequency band allocation step). Next, in response to the completion of the search based on the search rule, the assignment result is definitely stored without performing a display for confirming whether or not the assignment result is definitely stored (S0205, Memory step).

  (Simple description of the effect of Embodiment 1) As described above, the video receiver of this embodiment and the frequency band setting method of the video receiver reduce the operation performed by the user, and the frequency band by a simple operation method. Can be set. Further, it is possible to eliminate the occurrence of a situation where the key operation on the confirmation screen is wrong and the channel setting must be performed again from the beginning.

  << Embodiment 2 >> (Concept of Embodiment 2) The video receiving apparatus of the present embodiment is based on the video receiving apparatus of Embodiment 1, and the setting menu display section manages the setting menu hierarchically, and the frequency band. A higher-level setting menu is displayed after the search is completed.

  (Configuration of Embodiment 2) FIG. 3 is a diagram showing an example of functional blocks of the video receiving apparatus of this embodiment. As shown in this figure, the video receiving apparatus (0300) of the present embodiment is based on the first embodiment, and includes a “setting menu display unit” (0301), a “frequency band search unit” (0302), and “reception”.

As feature points, the “setting menu display section” (0301) further includes “menu hierarchy management means” (0305) and “upper hierarchy menu display means” (0306).

  (Description of Configuration of Embodiment 2) “Menu hierarchy management means” (0305) is a function of the setting menu display unit, and has a function of hierarchically managing display of setting menus. “Hierarchical management” means that each setting menu is divided into categories and managed by setting a hierarchy for each category. A setting menu of a certain hierarchy is arranged under a setting menu of an upper hierarchy having a similar common concept. Therefore, the relationship between the upper level setting menu and the setting menu arranged under the upper level setting menu has a one-to-one or one-to-many relationship. For example, in order to perform a frequency band search in the frequency band search unit, a menu for selecting which broadcast wave frequency band is to be searched and a menu for selecting which frequency band search method is to be used for the search Can be managed in a hierarchy. If there is more than one frequency band search method for one broadcast wave frequency band, the menu for selecting which broadcast wave frequency band search is to be used is which frequency band search method. This is a higher hierarchy than the menu for selecting whether to perform a search. FIG. 7 shows an example of a hierarchy menu managed by a plurality of hierarchies.

  The “upper layer menu display means” (0306) has a function of displaying a setting menu in the upper layer of the setting menu layer displayed for selecting this search upon completion of the search based on the search rule. When the frequency band search for one broadcast wave is completed, the user is expected to perform a frequency band search for a different broadcast wave rather than performing a frequency band search for the same broadcast wave again. Therefore, when the frequency band search for one broadcast wave is completed, the setting menu of the upper layer having a common upper concept is displayed to select which broadcast wave is to be searched next. By doing so, it is possible to increase the efficiency of the user's setting work. The upper layer menu displayed by the upper layer menu display means is not limited to the menu for selecting broadcast waves as described above. For example, when channel settings for all broadcast waves are completed, a higher-order menu than the menu for selecting broadcast waves may be displayed.

  (Processing Flow of Embodiment 2) FIG. 4 is a flowchart showing an example of the processing flow of this embodiment. As shown in FIG. 4, the setting menu display step (S0401) and the frequency band search step (S0402) are processed as in the case of the first embodiment. When the search is completed in the frequency band search step (S0403), a receivable frequency band allocation step (S0404) and a storage step (S0405) are processed according to the completion of the search. Then, on the setting menu display screen in the present embodiment, in response to the completion of the search based on the search rule, a setting menu in the upper hierarchy of the setting menu hierarchy displayed for selecting this search is displayed (S0406, S0406). Higher level menu display step). As shown in FIG. 4, the higher-level setting menu display step may be processed after storing the allocation result by the storage unit, or may be processed in parallel with other processing after the frequency band search is completed. .

  (Simple explanation of the effect of the second embodiment) As described above, the video receiving device of the present embodiment uses the menu display by predicting the operations that can be performed by the user after the frequency band search is completed. It is possible to reduce the burden on the person who sets the frequency band.

  << Embodiment 3 >> (Concept of Embodiment 3) The video receiving apparatus of the present embodiment is based on the video receiving apparatus of Embodiment 1 or 2, and is displayed to select this search when the frequency band search is interrupted. The displayed setting menu is displayed again.

  (Configuration of Embodiment 3) FIG. 5 is a diagram showing an example of functional blocks of the video receiving apparatus of this embodiment. As shown in FIG. 5, the video receiving apparatus (0500) of the present embodiment is based on the first embodiment, and includes a “setting menu display section” (0501), a “frequency band search section” (0502), and “reception”. In the case where the function of the second embodiment is added to the setting menu display unit, the “menu hierarchy management unit” and “possible frequency band allocation unit” (0503) and “storage unit” (0504) are provided. “Upper layer menu display means”. However, since the functional blocks have been described in the first embodiment, the description thereof is omitted. As a feature point, the “setting menu display section” (0501) further includes “same menu redisplay means” (0505).

  (Description of Configuration of Embodiment 3) “Same Menu Redisplay Unit” (0505) is a function of the setting menu display unit, and selects this search in response to a search interruption based on the search rule. The setting menu displayed for the purpose is displayed again. The “interruption of search” corresponds to a case where, during a frequency band search, a button for canceling the frequency band search is pressed by the user, and the search ends in the middle. The case where the user cancels the frequency band search is considered when the frequency band search is expected to take a long time and the user interrupts the frequency band search and views the video by external input. It is done. In this case, it is considered that the frequency band search is performed in order to set the channel of the broadcast wave again after the video viewing by the external input is completed. Further, it is considered that the frequency band search is performed again when a button for canceling the frequency band search is accidentally pressed. In these cases, the setting menu display unit displays again the setting menu displayed for selecting this search. The “setting menu displayed to select this search” is a menu finally selected to start the frequency band search. For example, when the setting menu is divided into hierarchies as in the second embodiment, when the search is interrupted, the frequency band search method that is the finally selected menu is selected. Display the menu. In this way, when the frequency band search is interrupted, the user is expected to perform the frequency band search again, so the same setting menu as the setting menu displayed for selecting the search is displayed. .

  (Processing Flow of Embodiment 3) FIG. 6 is a flowchart showing an example of the processing flow of this embodiment. As shown in FIG. 6, the setting menu display step (S0601) and the frequency band search step (S0602) are processed as in the case of the first embodiment. When the search is completed in the frequency band search step (S0603), the receivable frequency band allocation step (S0604) and the storage step (S0605) are processed according to the completion of the search. On the other hand, when the search is interrupted in the frequency search step, the setting menu displayed for selecting the search is displayed again according to the interrupt of the search (same menu redisplay step, S0606). When an item for frequency band search is selected from the menu displayed again, the frequency band search is performed again.

  (Simple explanation of effect of Embodiment 3) As described above, in the video receiving apparatus of this embodiment, when the frequency band search is interrupted, an operation that can be performed by the user is predicted and the menu is displayed. Thus, it is possible to reduce the burden of the user's frequency band setting work.

  << Embodiment 4 >> (Concept of Embodiment 4) The video receiving apparatus of the present embodiment is based on the video receiving apparatus described in Embodiment 2 or 3, and the menu hierarchy management means is changed from the first hierarchy to the fourth hierarchy. It is characterized by managing a divided menu hierarchy.

  (Configuration of Embodiment 4) FIG. 7 is a diagram showing an example of a setting menu hierarchy of the video receiving apparatus of this embodiment. The video reception device according to the present embodiment is based on the video reception device described in the second or third embodiment, and includes a “setting menu display unit”, a “frequency band search unit”, a “receivable frequency band allocation unit”, , “The storage unit”, and “the menu hierarchy management unit” and “the upper layer menu display unit” in the setting menu display unit. However, since the functional blocks have been described in the first or second embodiment, the description thereof is omitted. The menu hierarchy management means of this embodiment manages a “setting menu hierarchy” (0700) in which setting menus are hierarchically categorized. The setting menu hierarchy includes “first hierarchy” (0701), “second hierarchy” (0702), “third hierarchy” (0703), and “fourth hierarchy” (0704). The selection of the setting menu for executing the search by the frequency band search unit is performed by selecting the “automatic setting button” (0705) or “terrestrial digital setting menu” of the fourth hierarchy under the “terrestrial analog setting menu” of the third hierarchy. It is the “automatic setting button” (0709) of the fourth hierarchy under it.

  (Description of Configuration of Embodiment 4) The “setting menu hierarchy” (0700) is managed by the menu hierarchy management means. The setting menu hierarchy is obtained by classifying setting menus into categories. The deeper the hierarchy, the more specific the setting menu will be selected. In addition, the user can grasp what setting is currently performed by knowing in which hierarchy the user is selecting the setting menu.

  The “first hierarchy” (0701) is a hierarchy positioned at the top of the setting menu hierarchy, and includes a “video adjustment menu”, “audio adjustment menu”, “energy saving setting menu”, and “main body setting menu”. is there. In the “video adjustment menu”, the brightness, color density, hue, image quality, and the like of the video displayed on the video receiver can be adjusted by adjusting the display settings. In the “audio adjustment menu”, by adjusting the setting of the audio signal output to the speakers, it is possible to adjust the high / low sounds, adjust the balance of the speakers provided on the left and right of the video reception device, and the like. In the “energy saving setting menu”, the energy saving setting can be performed by setting “no signal off”, “no operation off”, and the like. “No signal off” is a setting such that the power is turned off after about 15 minutes when a no-signal state such as the end of a broadcast signal. “Non-operation off” is a setting that automatically turns off the power of the video receiving apparatus when no operation is performed for three hours or more. In the “main body setting menu”, a region setting menu, a channel setting menu, an antenna setting menu, and a speaker setting menu can be selected. The setting menu of the second layer under the main unit setting menu will be described below.

  The “second layer” (0702) is a layer located under the main unit setting menu, and includes a “region setting menu”, “channel setting menu”, “antenna setting menu”, and “speaker setting menu”. In the “Region Setting Menu”, it is possible to register a region where the video receiving device is used in order to receive the terrestrial digital broadcast channel. By registering a region, the frequency band of terrestrial digital broadcasts received in that region can be efficiently searched. In the “antenna setting menu”, the antenna level can be set to the maximum by adjusting the direction of the BS digital antenna and the CS digital antenna. When the antenna setting menu is selected, the antenna level corresponding to the direction of the antenna is displayed on the setting menu display section, and the antenna level can be adjusted to the maximum while checking the displayed antenna level. In the “speaker setting menu”, when an external speaker is connected in addition to the speaker provided in the video receiving device, it is possible to set to which speaker the audio output destination is switched and output. In the “channel setting menu”, reception settings for terrestrial analog broadcast signals, terrestrial digital broadcast signals, BS digital broadcast signals, and CS digital broadcast signals can be made. The setting menu of the third hierarchy under the channel setting menu will be described below.

  The “third layer” (0703) is a layer located under the channel setting menu, and includes a terrestrial analog setting menu, a terrestrial digital setting menu, a BS digital setting menu, and a CS digital setting menu. When each setting menu is selected and a setting button located in the fourth hierarchy is selected, it is possible to search for the frequency band of each broadcast wave, assign the frequency band to the identifier, and store the assignment result to the storage unit.

  The “fourth hierarchy” (0704) is a hierarchy located under the terrestrial analog setting menu, the terrestrial digital setting menu, the BS digital setting menu, and the CS digital setting menu. The terrestrial analog setting menu has automatic setting buttons, additional setting buttons, area number setting buttons, and individual setting buttons, and the terrestrial digital setting menu has automatic setting buttons, additional setting buttons, and individual setting buttons. The BS digital setting menu has an individual setting button, and the CS digital setting menu has an individual setting button.

  When the “Automatic setting button” (0705) in the “Terrestrial analog setting menu” is selected, the frequency band search unit automatically searches the VHF and UHF frequency bands that can be received in the current radio wave condition of the place where the video receiver is used Then, it is assigned to a predetermined identifier by the receivable frequency band assigning unit, and this assignment result is definitely stored in the storage unit. When assigning a frequency band to an identifier for the first time, or when erasing a previously stored frequency band and reassigning a new frequency band, settings are made with the “automatic setting button”. When “additional setting button” (0706) in the “terrestrial analog setting menu” is selected, the assignment is made without erasing the result of assignment of the frequency band assigned to the identifier stored in the storage unit by the automatic setting button or the like. It is possible to assign a frequency band to an identifier that is not. When the “Region number setting button” (0707) in the “Terrestrial analog setting menu” is selected, the identifier is preset for each region without performing a frequency band search by the region number preset in the region setting menu. The frequency band that is expected to be received can be allocated. The region number is set using, for example, a region number list shown in FIG. For example, when the area where the video reception apparatus is used is “Sapporo”, the frequency band of the reception channel number 1 is assigned to the identifier 1 by setting the area number “001”. When “Individual setting button” (0708) of “Terrestrial analog setting menu” is selected, the frequency band search is individually performed in an area not applicable to the area number list, or assigned to an identifier stored in the storage unit. When deleting a frequency band, it is possible to review allocation of frequency bands for each identifier.

  When “Automatic setting button” (0709) in the “terrestrial digital setting menu” is selected, the frequency band of terrestrial digital broadcasting that can be received in the area where the video receiver is used is automatically searched, and the receivable frequency band is assigned to the identifier. The allocation result can be stored in the storage unit. Note that terrestrial digital broadcasting can be received by a UHF compatible antenna. When the “additional setting button” (0710) of the “terrestrial digital setting menu” is selected, the frequency band of the newly started broadcast channel is additionally registered after the frequency band is set by the automatic setting button of the terrestrial digital setting menu. Can do. In this case, the frequency band assignment result already stored in the storage unit remains stored. When the “individual setting button” (0711) of the “terrestrial digital setting menu” is selected, the assignment result of the identifier and the frequency band stored in the storage unit is individually deleted, or the frequency band assigned to the identifier is not changed. However, it is possible to individually set the frequency band so that it cannot be selected.

  When an “individual setting button” (0712) in the “BS digital setting menu” or an “individual setting button” (0713) in the “CS digital setting menu” is selected, the channel for each channel of BS digital broadcasting or CS digital broadcasting is displayed. It can be set so that cannot be selected. In BS digital broadcasting or CS digital broadcasting, it is not necessary to perform a frequency band search, but it is necessary to adjust the direction of the antenna in order to maximize the antenna level in the antenna setting menu.

  (Processing flow of Embodiment 4)

  A method for selecting each layer when the frequency band setting of the terrestrial analog signal is automatically performed in the video receiving apparatus of this embodiment will be described below with reference to FIGS.

  In the video receiving apparatus of the present embodiment, first, the main body setting menu is selected from the setting menu of the first hierarchy displayed as shown in FIG. When the main menu is selected, as shown in FIG. 9, a setting menu for the second layer under the main menu is displayed. Next, the channel setting menu is selected from the setting menu of the second hierarchy. When the channel setting menu is selected, as shown in FIG. 10, a setting menu in the third hierarchy under the channel setting menu is displayed. Next, the ground analog setting menu is selected from the setting menu of the third hierarchy. When the terrestrial analog setting menu is selected, as shown in FIG. 11, a fourth level setting menu is displayed. Select the automatic setting button from the setting menu of the fourth layer. Then, the frequency band search unit searches for a receivable frequency band according to a predetermined search rule. If a screen as shown in FIG. 12 is displayed during the search, the user can easily understand that the frequency band is being searched. When the search for the receivable frequency band is completed, the receivable frequency band assigning unit assigns the receivable frequency band to a predetermined identifier, and the assignment result is displayed in the storage unit without displaying the confirmation screen illustrated in FIG. Stored deterministically.

  When the search is completed, the setting menu display unit can display the setting menu of the third hierarchy shown in FIG. 10 and perform a frequency band search in different broadcast waves. That is, even if the user does not perform the operation of returning to the previous screen, it is possible to perform a frequency band search for a terrestrial digital signal or the like from the terrestrial digital setting menu, following the frequency band search for a terrestrial analog signal. If the search is interrupted in the middle, the user needs to perform a frequency band search again in order to complete the setting, so the setting menu for the fourth layer shown in FIG. 11 is displayed again.

  (Simple explanation of the effect of the fourth embodiment) As described above, in the video receiving apparatus of the present embodiment, the setting menu is managed hierarchically, and it is intuitively what the user is trying to set. In addition to being easy to understand, it is possible to reduce the burden of user frequency band setting work by predicting operations that can be performed by the user in response to completion or interruption of the search and displaying a hierarchically managed menu display. it can.
