These means are realized by a program except for the condition information storage unit 55 and the memory table 56.

  The detecting means 51 detects whether the communication function unit 1 is in a use state related to a voice call or a mail function. The detecting unit 51 detects using the output of the open / close detection unit 24, and detects the power supply unit / capacity detection unit 25. Detection is performed using the output, the presence / absence of key operation in the key operation unit 22 is detected, and the use state of the LCD 18 as the display unit based on the program being executed is displayed in the received information display received from the first broadcast. It is to detect whether or not it is used. The switching unit 52 performs broadcast switching in the digital broadcast receiving unit based on the detection result of the detecting unit 51 when the digital broadcast receiving unit is receiving 3 segment broadcast or 1 segment broadcast. The display control unit 53 displays a switching permission message on the LCD 18 constituting the display unit before the switching unit 52 performs switching. The switching control unit 54 controls switching by the switching unit 52 based on a response input to the switching permission message.

  The condition information storage unit 55 stores broadcast switching condition information by the switching means 52. For example, as shown in FIG. 4, in the folded state of the housing, the condition information storage unit 55 receives a one-segment broadcast without a switching permission message. The condition information indicating the transition to is stored. In addition, when the switching permission message is displayed and permission is given, the display unit shifts to reception from one-segment broadcasting. When the remaining battery level falls below a predetermined level, or when there is no key operation for a predetermined time, the display unit Condition information indicating a case where a certain LCD is not used for digital terrestrial broadcasting (for example, when the entire LCD is used for mail transmission / reception or Internet site viewing) is stored. For these reverse movements (for example, when the battery is charged and the remaining battery level falls below a predetermined level, or when the entire LCD is used for sending / receiving emails or viewing Internet sites) The return condition information for returning the broadcast to the three-segment broadcast is set. In addition to this, when recording or downloading from the three-segment broadcast, it is set not to shift to reception from the one-segment broadcast (switching prohibition condition information).

  The memory table 56 stores in advance information indicating which of the three-segment broadcast and the one-segment broadcast is received in association with the genre of the reserved program by EPG. FIG. 5 shows the contents of the information stored in the memory table 56. In this example, news and sports are set to be received from one-segment broadcasting.

  The main control unit 20 of the mobile phone having the above-described configuration executes programs corresponding to the flowcharts shown in FIGS. 6, 7, and 8, with respect to reception from the three-segment broadcasting and the one-segment broadcasting. Since the means is realized, the operation will be described based on this flowchart. FIG. 6 shows an operation corresponding to the folded state of the housing. Initially, in the case of receiving digital radio broadcasts of three-segment broadcasting (ST11), the closed state (folded state) of the casing is detected based on the output of the open / close detection unit 24 (S21). When it is detected, control information is sent to the OFDM demodulator 31 and the controller 44 of the backend unit 40 to selectively switch to digital radio broadcast reception of one segment broadcast (S22). As a result, the process shifts to a state in which a one-segment broadcast digital radio broadcast is being received (ST12).

  In a state of receiving a one-segment broadcast digital radio broadcast (ST12), the case is detected based on the output of the open / close detection unit 24 (S23). When it is detected, control information is sent to the OFDM demodulator 31 and the controller 44 of the backend unit 40 to switch to digital radio broadcast reception of three-segment broadcast (S24), and broadcast selection is restored. Thereby, it again shifts to the state (ST11) in which the digital radio broadcast of the 3 segment broadcast is being received. In states ST11 and ST12, it is detected that terrestrial digital radio broadcast reception has been turned off, and the processing corresponding to this flowchart is terminated upon receipt of an off operation. The process corresponding to the flowchart shown in FIG. 6 is performed separately from the process based on the output of the open / close detection unit 24, but is also performed in the process corresponding to the flowchart shown in FIG. You may do it.

  As shown in FIG. 7, the main control unit 20 starts receiving digital radio broadcasts, and in the state of receiving digital radio broadcasts of three-segment broadcasts (ST11), whether there has been a change in the usage state related to the communication function unit 1 It is detected (S31). That is, it is detected based on the output of the power supply unit / capacity detection unit 25 whether the remaining battery level has fallen below a predetermined level, whether there is no key operation for a predetermined time is detected based on an interrupt from the key operation unit 22, and the display unit It is detected whether the use state of the LCD 18 is not for terrestrial digital broadcasting based on a program being executed such as a mail transmission / reception mode or a web browser being activated.

  In step S31, when it is detected that there is a change in the usage state related to the communication function unit 1, the condition information storage unit 55 is searched to detect switching condition information corresponding to the change (S32), and then to the one-segment broadcast. It is detected whether it corresponds to the switching prohibition condition information (S33), and it corresponds to the switching prohibition condition information at the time of recording or downloading for the three segment broadcast, and the state ST11 is continued. On the other hand, if it branches to NO without corresponding to the switching prohibition condition information in step S33, it is detected whether the switching condition information is to display a switching permission message (S34).

  When branching to YES in step S34, for example, a switching permission message such as “Do you want to receive 1 segment? Yes / No” is displayed on the LCD 18 (S35) and whether the input is “Yes” or “No”. It detects (S36). If it is detected in this step S36 that “NO” has been input (operated), the state ST11 is continued. On the other hand, if it is detected in step S36 that “Yes” has been input, control information is sent to the OFDM demodulator 31 and the controller 44 of the back end unit 40 to switch to digital radio broadcast reception of one segment broadcast (S37). ). As a result, the process proceeds to a state (ST12) in which a one-segment broadcast digital radio broadcast is being received.

  In the state of receiving the digital radio broadcast of one segment broadcast (ST12), the establishment of the return condition for changing the received broadcast to the three segment broadcast is monitored based on the return condition information stored in the condition information storage unit 55. (S38) When, for example, Internet site viewing ends and this return condition is satisfied, control information is sent to the OFDM demodulator 31 and the controller 44 of the backend unit 40 to switch to reception of digital radio broadcast of 3 segments broadcast ( S39). Thereby, it again shifts to the state (ST11) in which the digital radio broadcast of the 3 segment broadcast is being received.

  In the process corresponding to the flowchart shown in FIG. 7, when the process based on the output of the open / close detection unit 24 is performed, the process proceeds from step S31 to step S34 by detecting the closed state, and in this step S34, the process branches to NO. In step S37, switching to digital radio broadcast reception of 1 segment broadcast is performed. As described above, the present embodiment includes the condition information storage unit 55 in which the condition information for switching the broadcast is stored. When the broadcast is switched based on the information in the condition information storage unit 55, the condition information storage unit 55 includes By storing information related to folding status, remaining battery power, no key operation for a predetermined time, usage status of the display, recording or downloading, transition to non-segment broadcasting reception in each case It is convenient because it can be controlled.

  Further, the main control unit 20 of the cellular phone performs selection control of whether the received broadcast is a three-segment broadcast or a one-segment broadcast at the start of receiving a reserved program by EPG according to the flowchart shown in FIG. That is, when the reception program is started and the reception of the reserved program by the EPG is detected by the activated program (S41), and the start is by a manual operation that is not a reserved program, the received broadcast is shown as a three-segment broadcast in the flowchart shown in FIG. The process proceeds to the corresponding process (S42).

  On the other hand, if “YES” in the step S41, the memory table 56 is referred to and it is detected whether the program is set to be received from the one-segment broadcasting (S43, S44). If it is detected in step S44 that the program is set to be received from the one-segment broadcast, the program is switched to the one-segment broadcast digital radio broadcast reception (S45). As a result, the state shifts to a state in which the digital radio broadcast is being received from the one-segment broadcast (ST12), and this state S12 is continued until a program end or reception end operation. On the other hand, if branching to NO in step S44, the received broadcast is changed to a three-segment broadcast and the process proceeds to a process corresponding to the flowchart shown in FIG. 7 (S42).

  Thus, in the mobile phone according to the present embodiment, the broadcast is changed so as to be received from the one-segment broadcast according to the use state related to the communication function unit 1 including opening / closing of the housing, etc. It is possible to suppress power consumption as much as possible. In the above example, when the housing is closed, the one-segment broadcast is received without outputting the switching permission message. However, the switching permission message is sent to the sub-LCDs of the two LCDs. You may make it display, and you may comprise so that a warning sound may be emitted and it may switch to reception of 1 segment broadcast.

  Furthermore, the present invention can be applied not only to digital broadcasts related to 1-segment broadcast reception and 3-segment broadcast reception, but also to other digital broadcasts that can receive only sound and selectively receive sound and data. Further, the switching operation is not limited to the contents described in the present embodiment, and various inventions can be formed by appropriately combining a plurality of constituent elements disclosed in the respective embodiments. it can. For example, some components may be deleted from all the components shown in the embodiment. Furthermore, constituent elements over different embodiments may be appropriately combined. In the above embodiment, the one-segment broadcast to be switched is a partial reception of three-segment broadcast (reception of only audio) and the program is the same, but it may or may not be the same at the same time. The first broadcast and the second broadcast may be configured as separate broadcasts.
