4 to 10 are flowcharts for explaining the operation of the present embodiment. Hereinafter, with reference to FIG. 1 to FIG. 10, the operation of the present embodiment when the configuration examples are the above-described configuration examples A, C, and B will be sequentially described.
1) In the case of configuration example A,
In this configuration example, the master unit (20), which is a television receiver, includes one terrestrial digital full-segment tuner, and the remote control device (10) includes one one-segment tuner. . Further, it is assumed that 10 terrestrial digital broadcasts can be received in the corresponding area.

  The remote control operator is watching a large TV (parent machine (20)) with his / her family in the living room and intends to change to another channel because the current program is boring.

  First, the operator picks up the remote control device (10) and starts the remote control operation. This is recognized by the operation start recognition means (180). Appropriate means can be adopted as a specific configuration of the recognition means. For example, it can be realized by a method of attaching an acceleration sensor to the remote control device (10) and recognizing the start of operation by an impact at the start of the operation, a method of recognizing when a button for recognizing the start of operation is pressed, or the like.

  When the start of remote control operation is recognized by the operation start recognition means (180), the remote control operation shown in FIG. 4 is entered. First, the current channel acquisition process received by the broadcast receiving means (140) is entered (4-20). At this time, if the parent device (20) side and the remote control device (10) side are provided with channel notification means by mutual communication, the current channel acquisition processing of FIG. 5 is entered. In the current channel acquisition process of FIG. 5, an inquiry is made to the master unit (20) (5-20). In response to this, on the base unit (20) side, the base unit (20) side channel acquisition inquiry process of FIG. 8 operates.

  In the channel acquisition inquiry process on the master unit (20) side in FIG. 8, after receiving the current channel acquisition query from the remote control device (10-20), the channel currently received by the master unit (20) is acquired. (8-30) and responds (8-40) to the remote control device (10) with the content, and the processing on the base unit (20) side ends (8-50). The remote control device (10) receives the response from the master unit (20) (5-30), and ends the current channel acquisition process (5-40).

  When the channel notification by mutual communication is not supported, the current channel is determined locally on the remote control device (10) side. For example, the channel information designated by the corresponding remote controller (10) is stored as a specific channel, and when the start of the remote control operation is recognized, the stored channel information is read and acquired as the current channel ( 4-20).

  When the current channel is acquired in step (4-20) in this way, the channel change means (130) switches the reception channel of the broadcast receiving means (140) to the acquired current channel, and broadcast reception is performed. The means (140) receives the current channel (4-30), and the display means (160) displays the received broadcast content of the current channel (4-40).

  When the received broadcast content of the current channel is displayed (4-40), the remote control device (10) shifts to an event waiting state (4-50). In the event, the channel change means (130) changes the channel (4-60), the channel decision means (170) determines the channel (4-70), the operation end recognition means (190) ends the remote control operation (4-80) There is.

  In the channel change (4-60), the channel change process of FIG. 6 is executed. In the case of the configuration example A, since the number of receiving devices on the remote control device (10) side is 1, step (6-20) becomes No, and the channel received by the broadcast receiving means (140) is changed (6- 30). In the case of the configuration example A, step (6-50) and step (6-60) are not performed, and control is returned to step (4-60) immediately after step (6-70). Return to 30).

  In the event of channel determination (4-70), control is transferred to the channel determination process of FIG. The channel determination is performed when the operator wants to display the same program as the channel currently displayed on the display means (160) of the remote control device (10) on the master unit (20). When the channel determination key button provided on the surface of the remote control device (10) is operated, the reception channel information displayed on the display means (160) of the remote control device (10) in step (7-20) Is notified to the parent device (20) as channel switching information.

  In the master unit (20) that has received the channel switching information from the remote control device (10), the master unit side channel determination process of FIG. 10 is executed. In the case of the configuration example A, since the number of receiving devices on the base unit (20) side is 1, step (10-20) becomes No, and the base unit (20) side receives the broadcast of the designated channel. Start with (240) (10-30). With the extension, the master unit (20) outputs the broadcast contents of the corresponding channel to the display means (260).

If the remote control operation ends (4-80), the process ends. As a remote control operation end processing operation, for example, to the master unit (20), to notify the processing stop, or to perform processing such as receiving broadcast on the remote control device (10) side, canceling the display, etc. It can be realized by an appropriate processing operation, and is not particularly defined.
2) In the case of the configuration example C,
In this configuration example, the master unit (20), which is a television receiver, includes one terrestrial digital full-segment tuner, and the remote control device (10) includes three one-segment tuners. . Further, it is assumed that 10 terrestrial digital broadcasts can be received in the corresponding area.

  The remote control operator is watching a large TV (parent machine (20)) with his / her family in the living room and intends to change to another channel because the current program is boring. First, the operator picks up the remote control device (10) and starts the remote control operation (4-10). This is recognized by the operation start recognition means (180). The recognition means can be realized by the same means as the means described in the configuration example A.

  When the start of remote control operation is recognized by the operation start recognition means (180), the remote control operation shown in FIG. 4 is entered. First, the current channel acquisition process received by the broadcast receiving means (140) is entered (4-20). At this time, if the parent device (20) side and the remote control device (10) side are provided with channel notification means by mutual communication, the current channel acquisition processing of FIG. 5 is entered. In the current channel acquisition process of FIG. 5, an inquiry is made to the master unit (20) (5-20). In response to this, on the base unit (20) side, the base unit (20) side channel acquisition inquiry process of FIG. 8 operates.

  In the channel acquisition inquiry process on the master unit (20) side in FIG. 8, after receiving the current channel acquisition query from the remote control device (10-20), the channel currently received by the master unit (20) is acquired. (8-30) and responds (8-40) to the remote control device (10) with the content, and the processing on the base unit (20) side ends (8-50). The remote control device (10) receives the response from the master unit (20) (5-30), and ends the current channel acquisition process (5-40).

  When the channel notification by mutual communication is not supported, the current channel is determined locally on the remote control device (10) side. For example, the channel information designated by the corresponding remote controller (10) is stored as a specific channel, and when the start of the remote control operation is recognized, the stored channel information is read and acquired as the current channel ( 4-20).

  When the current channel is acquired in step (4-20) in this way, the channel change means (130) switches the reception channel of the broadcast receiving means (140) to the acquired current channel, and broadcast reception is performed. The current channel is received (4-30) by means (140). The received broadcast content of the current channel is displayed on the display means (160) (4-40).

  At this time, the other two of the receiving devices other than the one currently used for channel reception are positioned as spare receiving devices. If this spare receiving apparatus is in a non-reception state, “upper channel” and “lower channel” are selected from the current channel, and the corresponding channel is received in advance by the pre-receiving means (160).

  When the broadcast content of the current channel received by the broadcast receiving means (140) is displayed (4-40), the remote control device (10) shifts to an event waiting state (4-50). In the event, the channel change means (130) changes the channel (4-60), the channel decision means (170) determines the channel (4-70), the operation end recognition means (190) ends the remote control operation (4-80) There is.

  In the channel change (4-60), the channel change process of FIG. 6 is executed. In the case of the configuration example C, since the number of receiving devices on the remote control device (10) side is 3, it is determined whether or not the broadcast of the channel to be changed is being received by the standby receiving device (6-20). If step (6-20) is No, the channel received by the broadcast receiving means (140) is directly changed (6-30).

  If the step (6-20) is Yes, the spare receiving device already received is positioned as the current broadcast receiving means (140) (6-40) and is received by this spare receiving device. The broadcast content of the corresponding channel is displayed on the display means (160). In the case of configuration example C, step (6-50) is not performed.

  In step (6-60), the receiver other than the receiver that receives the broadcast corresponding to the current channel is positioned as a standby receiver (pre-reception means). In these two receivers, the channel above the current channel is Select “lower channel” and change to pre-receive these channels. In step (6-70), control is returned to immediately after step (4-60), and the process returns to step (4-30).

  In the event of channel determination (4-70), control is transferred to the channel determination process of FIG. The channel determination is performed when the operator wants to display the same program as the channel currently displayed on the display means (160) of the remote control device (10) on the master unit (20). When the channel determination key button provided on the surface of the remote control device (10) is operated, the reception channel information displayed on the display means (160) of the remote control device (10) in step (7-20) Is notified to the base unit (20).

  In the master unit (20) that has received the reception channel information from the remote control device (10), the master unit side channel determination process of FIG. 10 is executed. Also in the configuration example C, since the number of receiving devices on the base unit (20) side is 1, step (10-20) is No, and on the base unit (20) side, the reception of the designated channel is broadcasted. Start with means (240) (10-30). With the extension, the master unit (20) outputs the broadcast contents of the corresponding channel to the display means (260).

  If the remote control operation ends (4-80), the process ends. The remote control operation end processing operation is the same as in the configuration example A described above.

In the case of the configuration example C, a plurality of one-seg receiving means are provided on the remote control device (10) side, but the processing amount in the one-seg receiving means and the cost for the tuner are mounted on the base unit (20) side with a plurality of full-segments Can be realized smaller.
3) In the case of the configuration example B,
In this configuration example, the master unit (20), which is a television receiver, includes two terrestrial digital full-segment tuners, and the remote control device (10) includes one one-segment tuner. . Further, it is assumed that 10 terrestrial digital broadcasts can be received in the corresponding area.

  The remote control operator is watching a large TV (parent machine (20)) with his / her family in the living room and intends to change to another channel because the current program is boring. First, the operator picks up the remote control device (10) and starts the remote control operation (4-10). This is recognized by the operation start recognition means (180). The recognition means can be realized by the means described in the configuration example A.

  When the start of remote control operation is recognized by the operation start recognition means (180), the remote control operation shown in FIG. 4 is entered. First, the current channel acquisition process received by the broadcast receiving means (140) is entered (4-20). At this time, if the parent device (20) side and the remote control device (10) side are provided with channel notification means by mutual communication, the current channel acquisition processing of FIG. 5 is entered. In the current channel acquisition process of FIG. 5, an inquiry is made to the master unit (20) (5-20). In response to this, on the base unit (20) side, the base unit (20) side channel acquisition inquiry process of FIG. 8 operates.

  In the channel acquisition inquiry process on the master unit (20) side in FIG. 8, after receiving the current channel acquisition query from the remote control device (10-20), the channel currently received by the master unit (20) is acquired. (8-30) and responds (8-40) to the remote control device (10) with the content, and the processing on the base unit (20) side ends (8-50). The remote control device (10) receives the response from the master unit (20) (5-30), and ends the current channel acquisition process (5-40).

  When the channel notification by mutual communication is not supported, the current channel is determined locally on the remote control device (10) side. For example, the channel information designated by the corresponding remote controller (10) is stored as a specific channel, and when the start of the remote control operation is recognized, the stored channel information is read and acquired as the current channel ( 4-20).

  When the current channel is acquired in step (4-20) in this way, the channel change means (130) switches the reception channel of the broadcast receiving means (140) to the acquired current channel, and broadcast reception is performed. The means (140) receives the current channel (4-30), and the display means (160) displays the received broadcast content of the current channel (4-40).

  When the received broadcast content of the current channel is displayed (4-40), the remote control device (10) shifts to an event waiting state (4-50). In the event, the channel change means (130) changes the channel (4-60), the channel decision means (170) determines the channel (4-70), the operation end recognition means (190) ends the remote control operation (4-80) There is.

  In the channel change (4-60), the channel change process of FIG. 6 is executed. In the case of the configuration example B, since the number of receiving devices on the remote control device (10) side is 1, step (6-20) becomes No, and the channel received by the receiving device of the broadcast receiving means (140) is changed (6 -30). Next, the master unit (20) is notified that the temporary channel change has been performed (6-50).

  Upon receiving the notification of step (6-50), the base unit (20) performs the base unit side temporary channel change processing of FIG. First, a temporary channel change notification is received (9-10), and it is checked whether one of the two receiving devices of the broadcast receiving means (240) and the prior receiving means (240) is receiving the corresponding channel (9- 20). In the case of Yes, there is no particular processing. In the case of No, reception of the designated channel is started (9-30) in the preliminary receiving device (the side that is not the receiving device currently receiving the channel) of the prior receiving means (240), and the parent The process on the machine side is temporarily terminated (9-40).

  In the case of the configuration example B, step (6-60) is not performed, control is returned immediately after step (4-60) in step (6-70), and the process returns to step (4-30).

  In the event of channel determination (4-70), control is transferred to the channel determination process of FIG. The channel determination is performed when the operator wants to display the same program as the channel currently displayed on the display means (160) of the remote control device (10) on the master unit (20). When the channel determination key button provided on the surface of the remote control device (10) is operated, the reception channel information displayed on the display means (160) of the remote control device (10) in step (7-20) Is notified to the parent device (20) as channel switching information.

  In the master unit (20) that has received this channel switching information from the remote control device (10), the master unit side channel determination process of FIG. 10 is executed. First, it is checked whether the receiving device currently receiving the channel or the spare receiving device is receiving the channel determined by the remote control device (10-20).

  If the determined channel is received by either the receiving device that is currently receiving the channel or the backup receiving device (10-20, Yes), the receiving that is receiving this determined channel The apparatus is positioned as a broadcast receiving means (240) that is currently receiving a channel (10-40). If neither the receiving device receiving the current channel nor the standby receiving device has received the determined channel (10-20, No), the broadcast receiving means (240), that is, the current channel The channel is changed so as to receive the channel determined by the receiving device (10-30).

  By extension of step (10-40) or step (10-30), base unit (20) outputs the broadcast content of the corresponding channel to display means (260).

  If the remote control operation ends (4-80), the process ends. The remote control operation end processing operation is the same as in the configuration example A described above.

  In the case of this configuration example B, the remote control device (10) notifies the parent device (20) in advance of the channel to be changed in advance, and the spare receiver of the parent device (20) broadcasts the channel. Therefore, when the current channel of the base unit is changed, it can be realized by switching to a spare receiving device, and the delay time after changing the channel can be reduced.

  The operation in the configuration examples A, B, and C has been described above, but basically the same processing is performed in the configuration examples D, E, and F.

  However, in the case of the configuration examples E and F, the remote control device (10) is configured to include 10 one-segment tuners, and therefore, when 10 terrestrial digital broadcasts can be received in the corresponding area. The remote control device (10) is mounted so as to receive all broadcast stations in the corresponding area in advance.

  Therefore, when the channel change processing operation of FIG. 6 is executed using the configuration example E or the configuration example F, since the broadcast of the channel to be changed is received by any of the ten receiving devices, the step (6-20) ) And step (6-30) can be omitted, and the channel change processing time can be further shortened.

  In the above embodiment, the remote control device (10) has been described as a single remote control device attached to a television receiver or HDD recorder. However, the remote control device (10) is not necessarily an option for the TV or HDD recorder, and is a TV broadcast. It can also be realized as a configuration in which the remote control function of the present invention is incorporated in a mobile communication terminal such as a mobile phone having a reception function.

  In the above embodiment, it is assumed that the remote control side reception means is for one seg and the master side reception means is a digital full segment, but it is also possible to use analog reception means as simulcast on the remote control side. . In this case, however, it is necessary to provide a means for the remote controller to know information indicating which analog channel corresponds to which digital channel.

  When analog broadcast receiving means is used as receiving means on the remote control device side, there is almost no delay until imaging, so that zapping time by the remote control device can be shortened, and the number of tuners on the remote control side is minimized (for example, 1 ).

  In addition, in a system such as CATV where terrestrial data cannot be received by the remote control, another system such as a set top box outputs information for pre-selection by the remote control and receives it by the remote control. There can also be an implementation.
