Description

  The present invention relates to a digital broadcast receiver, and more particularly to a digital broadcast receiver for selecting a formation CH to be presented when a physical CH configured to have a plurality of formation channels (hereinafter also simply referred to as CH) is selected. About.

  In recent years, digital broadcasting has been performed. As digital broadcasting, for example, terrestrial digital broadcasting as well as BS digital broadcasting has been started. In digital broadcasting, one broadcasting station can simultaneously perform a plurality of broadcastings, and a physical CH corresponding to one broadcasting station is configured to have a plurality of organization CHs. FIG. 9 is a diagram schematically showing the configuration of the physical CH. In FIG. 9, U13, U14, and U15 are CH numbers of physical CHs. In addition, 011, 012 and the like indicated by three-digit numbers are CH numbers of the organization CH. A full segment is configured to have three layers of three organization CHs, and here, one of the three layers is shown. One seg is configured to have one hierarchy including three organization CHs, and here, one organization CH is shown among the three organization CHs. Of the formation CHs belonging to a certain physical CH, the formation CH having the smallest CH number is referred to as a primary service.

  In digital broadcasting, one broadcasting station can perform broadcasting using a plurality of organized channels as described above. For this reason, for example, when the baseball game broadcasted by the primary service is prolonged, the primary service can broadcast the program as scheduled, and can continue the baseball broadcast using another organization CH. In addition, for example, the primary service can broadcast a program for the whole country, and other program channels can also broadcast a program for the local.

  By the way, when a user selects a physical CH, it is necessary to select and present one of the formation CHs among the formation CHs belonging to the selected physical CH. On the other hand, in Patent Document 1, when an up / down key for sequentially selecting broadcast stations is operated, only one specific channel among a plurality of channels in each broadcast station is sequentially switched. Digital broadcast receivers have been proposed. In addition, since a broadcasting station generally performs broadcasting using a primary service as a main channel in the formation CH, it can be said that there is a low possibility that broadcasting is suspended in the primary service. For this reason, in the digital broadcast receiver proposed in Patent Document 1, it is proposed that the specific one channel is the smallest channel among the channels in each broadcast station.

JP 2001-008117 A

  According to the technique proposed by Patent Document 1, when a physical CH is selected, only a specific channel belonging to the selected physical CH (particularly, a primary service that is unlikely to be suspended) is displayed. Therefore, it is considered reasonable for convenience. However, the plurality of organization CHs belonging to the physical CH have different characteristics depending on the organization CH and each layer. For this reason, depending on the user, there is usually a case where it is desired to use a set-up CH other than the primary service, and a case where it is desired to use a set-up CH having a different characteristic for each physical CH is also conceivable. However, in the technique proposed in Patent Document 1, since a specific channel such as a primary service is first displayed, the user must further perform an operation for selecting a desired organization CH after that. There was a risk of inconvenience.

  Therefore, the present invention has been made in view of the above problems, and a digital broadcast receiver capable of appropriately selecting a formation CH to be presented when a physical CH is selected and improving convenience for a user. The purpose is to provide.

In order to solve the above-described problems, the present invention provides a function for selecting a physical channel based on an operation of an up / down operation means for sequentially selecting a physical channel having a plurality of organized channels, and a physical channel. And a function of presetting a composition channel corresponding to the physical channel, and a composition to be presented when a physical channel selected based on the operation of the up / down operation means is preset As the channel, there is provided a specific knitting channel selection means for selecting a preset knitting channel corresponding to the physical channel selected based on the operation of the up / down operation means, and the channel is selected based on the operation of the up / down operation means. If the physical channel is not preset, the specific organization channel Channel selection means, a programmed channel presenting, among programmed channel belonging to a physical channel that is based on and tuned to the operation of the up-down operation means, and selects the primary service.

  According to the present invention, when a physical CH is selected, a preset organization CH corresponding to the selected physical CH is selected, so that the user can quickly use a desired organization CH. As a result, the user does not have to perform an operation for further selecting the formation CH, and according to the present invention, the convenience for the user can be improved. It should be noted that the present invention is configured so that the user can quickly use a desired organization CH when a physical CH is selected, and the technical idea is different from the technology proposed in Patent Document 1. . Further, in relation to the configuration as described above, the present invention is not limited to the fact that the organization CH to be selected in the present invention is always selected when the physical CH is selected as shown below. It is considered that the configuration is different from the technique proposed in Patent Document 1 configured to sequentially switch only one channel.

Also, when the physical CH that tuning is not preset, for example, if, as generally use frequency selects a primary service, which is considered high as in the present invention, it is reasonable as convenience.

  The present invention also provides that when the physical channel selected based on the operation of the up / down operation means is not preset, the specific composition channel selection means selects the composition channel to be presented based on the operation of the up / down operation means. Of the organized channels belonging to the stationed physical channel, the organized channel with the smallest channel number may be selected in the same hierarchy as that selected before the channel selection. Further, when the selected physical CH is not preset, for example, according to the present invention, it is possible to continuously present the organization CH of the same hierarchy to the user, and thereby, the organization CH of the same color as the desired organization CH The convenience can be improved in that it can be presented to the user.

  In the present invention, when a plurality of physical channels selected based on the operation of the up / down operation means are preset, the specific composition channel selection means is based on the operation of the up / down operation means as the composition channel to be presented. Of the selected plurality of preset physical channels, a preset organization channel may be selected corresponding to the physical channel with the smallest preset number. When a plurality of physical CHs are preset, for example, as in the present invention, if the organization channel preset corresponding to the physical CH with the smallest preset number is selected, the user can respond accordingly. By performing the presetting in advance, the desired knitting CH can be used quickly. As a result, the user does not have to further perform an operation for selecting the composition CH, and according to the present invention, the convenience for the user can be improved.

  In the present invention, when the physical channel selected based on the operation of the up / down operation means is preset and the organization channel is not preset corresponding to the selected physical channel, the specific organization channel selection is performed. The means may select a primary service among the organized channels belonging to the physical channel selected based on the operation of the up / down operation means as the organized channel to be presented. Further, when the organization CH is not preset corresponding to the selected physical CH, it is reasonable as a convenience to select the primary service as in the present invention, for example.

  In the present invention, when the physical channel selected based on the operation of the up / down operation means is preset and the organization channel is not preset corresponding to the selected physical channel, the specific organization channel selection is performed. As the organization channel to be presented, the organization channel having the smallest channel number in the same hierarchy as the hierarchy selected before the channel selection among the organization channels belonging to the physical channel selected based on the operation of the up / down operation means. A channel may be selected. Further, when the organization CH is not preset corresponding to the selected physical CH, for example, according to the present invention, the organization CH having the same characteristic as the desired organization CH can be presented to the user. Convenience can be improved.

  In the present invention, when the physical channel selected based on the operation of the up / down operation means is preset, and the organization channel preset corresponding to the selected physical channel is inappropriate, The specific organization channel selection means may select a primary service from among the organization channels belonging to the physical channel selected based on the operation of the up / down operation means as the organization channel to be presented. Also, if the preset organization CH corresponding to the selected physical CH is inappropriate (if it is not the organization CH belonging to the selected physical CH, or if the preset organization CH is not broadcast) For example, if the primary service is selected as in the present invention, it is reasonable for convenience.

You may select the organization channel with a small channel number. In addition, if the preset organization CH corresponding to the selected physical CH is inappropriate, for example, according to the present invention, the same special feature organization CH can be presented to the user as the desired organization CH. In this respect, convenience can be improved.

  Further, in the present invention, when the broadcasting is stopped on the organization channel having the smallest channel number in the same layer as the layer selected before the channel selection, the specific organization channel selection means as the organization channel to present, The primary service may be selected from the organized channels belonging to the physical channel selected based on the operation of the up / down operation means. Furthermore, when the broadcast is stopped on the organization channel with the smallest channel number in the same layer as that selected before channel selection, it is convenient if the primary service is selected as in the present invention. As reasonable as possible.

  Note that the layer selected before channel selection can be stored as information, and the physical channel is selected when a layer different from the layer to which the primary service belongs is selected. As a result, the primary service selects In addition, when the hierarchy is switched to a different hierarchy, the information of the hierarchy selected before channel selection need not be updated to the hierarchy to which the primary service belongs. As a result, when a physical channel is selected after the primary service has been selected, the same composition CH as before the primary service is selected can be presented to the user as the desired composition CH. .

  According to the present invention, it is possible to provide a digital broadcast receiver capable of suitably selecting a formation CH to be presented when a physical CH is selected and improving convenience for the user.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings.

  FIG. 1 is a diagram schematically showing the configuration of a digital broadcast receiver 100A. The antenna 1 is configured to receive a digital broadcast wave, and the digital broadcast wave received by the antenna 1 is input to the demodulation unit 3 through the tuner unit 2. The demodulator 3 has a configuration for demodulating the modulated signal. The decoding unit 4 is configured to decode the demodulated signal into content data such as digital audio and digital video. The control unit 5 is configured to perform channel selection control, program information management, and preset information management and control, and is realized by a CPU (Central Processing Unit). The memory 6 is a memory for the control unit 5 and is configured to hold various information related to control of the control unit 5 such as preset information. The information processing unit 7 is configured to perform user interface control and screen display control, and is realized by a CPU. The memory 8 is a memory for the information processing unit 7 and has a configuration for holding setting information, screen display information, and the like.

  The input unit 9 is an input interface composed of a touch panel 20, a remote controller 30, and the like. The video composition unit 10 is configured to synthesize broadcast content video and on-screen display by the information processing unit 7. The D / A unit 11 has a configuration for converting digital audio into analog audio, and the D / A unit 12 has a configuration for converting digital video into analog video. The audio output unit 13 includes an amplifier, a speaker, and the like, and outputs audio. The video output unit 14 is composed of a video output device such as a monitor, and outputs video.

  Next, the channel selection function and preset function provided in the digital broadcast receiver 100A will be described in detail. FIG. 2 is a diagram schematically illustrating an example of the touch panel 20 constituting the input unit 9. FIG. 3 is a diagram schematically showing an example of the remote controller 30 constituting the input unit 9. Both the touch panel 20 and the remote controller 30 are configured to have a preset channel selection key, a physical CH up / down key as a physical CH up / down operation means, a service switching key, and a mode switching key.

  The preset channel selection key is a key for performing an operation for directly performing a preset call to a preset physical CH. The physical CH up / down key is a key for performing an operation of sequentially selecting physical CHs. The service switching key is a key for performing an operation of switching the organization CH belonging to the selected physical CH. The mode switching key is a key for switching the layer to be received, and is mainly used for switching between the partial reception layer and the other layers. The control unit 5 performs control for selecting a physical channel based on the operation of the preset channel selection key and the operation of the physical channel up / down key.

  FIG. 4 is a diagram schematically illustrating an example of preset information. In the preset information, a physical CH is preset corresponding to a preset No (preset channel selection key No), and an organization CH is preset corresponding to the preset physical CH. In addition, full seg and one seg knitting CH are preset as the knitting CH. For example, when preset No. 1 is called by operating the preset channel selection key, 042 ch is presented to the user when viewing the full segment, and 641 ch is presented to the user when viewing the one segment. In the preset information, the user can arbitrarily preset the organization CH, and the physical CH to which the organization CH registered at this time can be preset at the same time. Accordingly, by operating the preset channel selection key, the user can directly and quickly call the desired organization CH.

  Returning to FIG. 1, when the physical CH selected based on the operation of the physical CH up / down key is preset, the memory 6 selects the physical CH selected based on the operation of the physical CH up / down key as the organization CH to be presented. A program for selecting a specific knitting CH for selecting a knitting CH preset for each of the above is stored. In the present embodiment, the specific knitting channel selection means is realized by the control unit 5 performing processing based on the specific knitting CH selection program. The specific organization CH selection program and preset information may be stored in, for example, the memory 8. At this time, the information processing unit 7 performs the processing based on the specific organization CH selection program stored in the memory 8 to specify the program. A knitting channel selection means may be realized.

  Further, the specific organization CH selection program is further created as shown below. The program for selecting a specific organization CH selects the physical channel selected based on the operation of the physical CH up / down key as the organization CH to be presented when the physical channel selected based on the operation of the physical CH up / down key is not preset. It is created so as to select the primary service among the organization CHs belonging to CH. In addition, when a plurality of physical CHs selected based on the operation of the physical CH up / down key are preset, the specific organization CH selection program selects a channel based on the operation of the physical CH up / down key as the organization CH to be presented. Of the plurality of preset physical CHs, the preset organization CH is selected so as to correspond to the physical CH with the smallest preset number.

  In addition, the program for selecting a specific organization CH is preset when a physical CH that is selected based on the operation of the physical CH up / down key is preset, and the organization CH is not preset corresponding to the selected physical CH. As the organization CH to be presented, the primary service is selected from the organization CHs belonging to the physical CH selected based on the operation of the physical CH up / down key. Furthermore, in the program for selecting a specific organization CH, the physical CH selected based on the operation of the physical CH up / down key is preset, and the organization CH preset corresponding to the selected physical CH is inappropriate. In this case, the composition service to be presented is created so as to select the primary service among the composition CHs belonging to the physical CH selected based on the operation of the physical CH up / down key.

  FIG. 5 is a diagram schematically showing a specific example of the operation when the physical CH up / down key is operated during full segment viewing. When the physical CH up / down key is operated to raise the physical CH a plurality of times while the current physical CH is U13ch, it is assumed that U18ch is selected as a result of sequential channel selection. The U18ch selected at this time is preset in the preset information. For this reason, as the organization CH to be presented, 042ch preset corresponding to the selected U18ch is selected. Subsequently, when the physical CH is increased once, U19ch is selected. The U19ch selected at this time is not preset in the preset information. For this reason, as the organization CH to be presented, the primary service is selected from the organization CHs belonging to the selected U19ch.

  Subsequently, when the physical CH is increased once, U20ch is selected. A plurality of U20ch channels selected at this time are preset in preset information. For this reason, as the organization CH to be presented, 063ch preset corresponding to the U20ch having the smallest preset number (here, U20ch preset to preset No. 5) is selected from a plurality of preset U20ch. Subsequently, when the physical CH is increased once, U21ch is selected. The U21ch selected at this time is preset in the preset information, but the organization CH is not preset corresponding to this U21ch. For this reason, as the organization CH to be presented, the primary service is selected from the organization CHs belonging to the selected U21ch.

  Subsequently, when the physical CH is raised a plurality of times, it is assumed that U62ch is selected as a result of sequential channel selection. The selected U62ch is preset in the preset information, but the 081ch preset corresponding to this U62ch is not an organization CH belonging to the U62ch but an inappropriate organization CH. For this reason, as the organization CH to be presented, the primary service is selected from the organization CHs belonging to the selected U62ch. In this way, the user can select a desired knitting CH not only when the preset channel selection key is operated, but also when the physical channel up / down key is operated. It can be used quickly.

  Next, the operation of the digital broadcast receiver 100A will be described in detail using the flowchart shown in FIG. When the user performs a channel selection operation using the physical CH up / down key (step S11), the digital broadcast receiver 100A receives the selected physical CH (step S12). Subsequently, the digital broadcast receiver 100A determines whether or not the selected physical CH is preset (step S13). If a plurality of selected physical CHs are preset, it is determined that a plurality of preset channels are preset in this step. If the determination is negative, the digital broadcast receiver 100A selects the primary service as the organization CH to be displayed (step S20). On the other hand, if an affirmative determination is made in step S13, it is further determined whether the preset broadcast station and the received broadcast station are the same (step S14). That is, in this step, it is determined whether or not the preset organization CH belongs to the received physical CH, and whether or not the organization CH is preset in association with the selected physical CH. If a negative determination is made, the process proceeds to step S20.

  On the other hand, if an affirmative determination is made in step S14, the information on the preset CH that is preset in association with the selected physical CH is acquired (step S15). When a plurality of selected physical CHs are preset, information on the organization CH preset for the physical CH having the smallest preset No is acquired in this step. Subsequently, in the digital broadcast receiver 100A, it is determined whether or not the organization CH from which the information has been acquired can be selected (step S16). That is, in this step, it is determined whether or not broadcasting is being performed on the organization CH from which information is acquired. If a negative determination is made, the process proceeds to step S20.

  On the other hand, if an affirmative determination is made in step S16, a preset organization CH corresponding to the selected physical CH is selected as the organization CH to be presented and presented to the user (step S17). When a plurality of selected physical CHs are preset, the organization CH preset for the physical CH having the smallest preset No is selected and presented in this step. As described above, it is possible to realize the digital broadcast receiver 100A that can appropriately select the organization CH to be presented when the physical CH is selected and improve the convenience for the user.

  In the digital broadcast receiver 100B according to the present embodiment, the memory 6 stores a specific organization CH selection program created as shown below instead of the specific organization CH selection program described in the first embodiment. Except for this point, it is the same as the digital broadcast receiver 100A. In the present embodiment, a specific organization channel selection means is realized by the control unit 5 performing a process based on a specific organization CH selection program created as described below. Next, before describing the specific organization CH selection program according to the present embodiment in detail, the configuration of the physical CH will be described in detail with reference to FIG.

  As shown in FIG. 7, the physical CH is configured with a plurality of organized CHs, and the physical CH is configured with a full segment and a one segment. Further, in FIG. 7, it is shown that broadcasting is being performed on the organization CH in which the CH number is displayed. Full Seg has three layers (TV service, data service 1 and data service 2) consisting of three organization CHs, and One Seg has one layer (data service) consisting of three organization CHs. Configured. That is, the organization CH has different characteristics such as TV service and data service 1 for each layer. It should be noted that among the formation CHs belonging to a certain physical CH as indicated by the arrows in the figure, the formation CH with the smallest CH number is the primary service.

  Next, the specific organization CH selection program according to the present embodiment will be described in detail. Similarly to the specific organization CH selection program described in the first embodiment, the specific organization CH selection program according to the present embodiment is preset when the physical CH selected based on the operation of the physical CH up / down key is preset. As the organization CH to be presented, the organization CH that is preset in correspondence with the physical CH selected based on the operation of the physical CH up / down key is selected. In addition, in the program for selecting a specific organization CH according to the present embodiment, when a plurality of physical CHs selected based on the operation of the physical CH up / down key are preset, the physical CH up / down key is displayed as the organization CH to be presented. Of the plurality of preset physical CHs selected on the basis of the operation, it is created so as to select the preset organization CH corresponding to the physical CH with the smallest preset number.

  On the other hand, the program for selecting a specific organization CH according to the present embodiment uses the physical CH up / down key as the organization CH to be presented when the physical CH selected based on the operation of the physical CH up / down key is not preset. Of the organization CHs belonging to the physical CH selected based on the operation, the organization CH is created so as to select the organization CH having the smallest CH number in the same layer as the layer selected before channel selection. In addition, in the specific organization CH selection program according to the present embodiment, the physical CH selected based on the operation of the physical CH up / down key is preset, and the organization CH is preset corresponding to the selected physical CH. If not, among the formation CHs belonging to the physical CH selected based on the operation of the physical CH up / down key as the formation CH to be presented, the highest CH number in the same layer as the layer selected before the channel selection Is created so as to select an organization CH having a small size.

  Further, in the specific organization CH selection program according to the present embodiment, the physical channel selected based on the operation of the physical CH up / down key is preset, and the organization is preset corresponding to the selected physical CH. The same hierarchy as the hierarchy selected before channel selection, among the organization CHs belonging to the physical CH selected based on the operation of the physical CH up / down key, as the organization CH to be presented when the CH is inappropriate And the organization CH having the smallest CH number is selected. In addition, the program for selecting a specific organization CH according to the present embodiment further presents the organization to be presented when the broadcast is stopped on the organization CH having the smallest CH number in the same layer as the layer selected before channel selection. As the CH, it is created so as to select the primary service among the organization CHs belonging to the physical CH selected based on the operation of the physical CH up / down key.

  In addition, the hierarchy selected before channel selection is held in the memory 6 as information, and this information is updated every time the hierarchy is switched to a different hierarchy. However, when a layer (for example, data service 1) different from the layer to which the primary service belongs (here, the TV service) is selected, the physical channel is selected, and as a result, the primary service is selected and the layer is different at the same time. When switching to a hierarchy (ie, TV service), in this embodiment, information on the hierarchy (ie, data service 1) selected before channel selection is not updated to the hierarchy (ie, TV service) to which the primary service belongs. It has become. As a result, when a physical channel is selected after the primary service has been selected, the same composition CH as before the primary service is selected can be presented to the user as the desired composition CH. .

  Next, the operation of the digital broadcast receiver 100B will be described in detail using the flowchart shown in FIG. This flowchart is the same as the flowchart shown in FIG. 6 except that steps S18 and S19 are added. Therefore, in this embodiment, steps S18 and S19 will be described in detail. If the determination in step S13, S14, or S16 is negative, the digital broadcast receiver 100B determines whether or not the channel with the smallest CH number in the same hierarchy can be selected (step S18). That is, it is determined whether or not broadcasting is performed on the organization CH having the smallest CH number in the same layer as that selected before channel selection in this step. If a negative determination is made, the process proceeds to step S20.

  On the other hand, if the determination in step S18 is affirmative, the digital broadcast receiver 100B selects the organization CH having the smallest CH number in the same hierarchy as that selected before channel selection, and prompts the user. Presented. Thus, convenience can be improved in that the same special color composition CH can be presented to the user as the desired composition CH. As described above, it is possible to realize the digital broadcast receiver 100B that can suitably select the organization CH to be presented when the physical CH is selected and improve the convenience for the user.

  The embodiment described above is a preferred embodiment of the present invention. However, the present invention is not limited to this, and various modifications can be made without departing from the scope of the present invention. For example, the preset information is preferably in a state in which a physical CH and composition CH arbitrarily preset by the user are already preset, but the physical CH and composition on which receivable broadcast is performed as a previous stage. The state may be a state in which the physical CH and organization CH that have been sought as CH are preset, or a state in which the user partially presets the physical CH and organization CH.
