  As described above, in the second embodiment, when an incoming call is received during recording, the call is started after the recording frame rate is reduced by half from 24 f / s to 12 f / s in response to a long press operation of the off-hook switch, and the on-hook operation is started. When the call is finished by the operation, the recording frame rate is returned from 12 f / s to 24 f / s. As a result, during the call period, the recording quality of the recording / playback unit 24 is reduced by halving the frame rate and the processing load on the control unit 12 is reduced. As a result, recording can be performed while maintaining the call quality. In the present embodiment, only the frame rate is changed. However, instead of this, the image size may be changed in accordance with the change of the frame rate.

D. Third Embodiment Next, an operation of incoming call detection processing according to the third embodiment will be described with reference to FIGS. 8 and 12. As in the first embodiment, when there is an incoming call during the execution of the main routine, the control unit 12 interrupts this process and proceeds to step SC1 shown in FIG. 8, where the TV receiver 20 is on or the recording / playback unit 24 It is determined whether the playback state is in any state. If it is in any state, the determination result is “YES”, and the process proceeds to the next step SC2, and in order to prioritize the incoming call of the mobile phone 1, the output of the broadcast received sound or the reproduced sound is stopped, and the process proceeds to step SC3. move on. On the other hand, if it is not in any state, the determination result in step SC1 is “NO”, and the process proceeds to step SC3. In step SC3, the incoming screen is superimposed on the display unit 18. Next, in step SC4, an incoming call notification for emitting a ringtone from the speaker 16 is performed. In subsequent step SC5, incoming call processing is executed depending on whether recording is in progress. Hereinafter, the operation will be described separately for a case where recording is not performed and a case where recording is being performed.

(A) When not recorded In this case, the determination result at step SC5 is “YES”, and the process proceeds to step SC6 to determine whether or not an off-hook operation is performed. If the off-hook operation is not performed, the determination result is “NO”, and the process returns to step SC4. Thereby, the incoming call notification is continued until the off-hook operation is performed. When an off-hook operation is performed, the determination result in step SC6 is “YES”, and the flow proceeds to step SC7. In steps SC7 to SC8, the call process is continued until an on-hook operation is performed. When the on-hook operation is performed, the determination result in step SC8 is “NO”, and the flow proceeds to step SC9 to execute the end call process.

  When the call termination process is completed, the control unit 12 advances the process to step SC10, and erases the incoming call screen displayed as a superimpose when the incoming call is detected. Subsequently, in step SC11, it is determined whether the TV receiver 20 is on or the recording / playback unit 24 is in a playback state. In any state, the determination result is “YES”, and the process proceeds to step SC12. After the audio output is resumed, the process proceeds to step SC47 shown in FIG. On the other hand, if it is not in any state, the determination result in step SC11 is “NO”, and the process proceeds to step SC47 in FIG. In step SC47, it is determined whether or not the recording is in progress. In this case, since the recording is not performed, the determination result is “NO”, and this processing is completed.

(B) During Recording When an incoming call is detected during recording, the determination result at step SC5 (see FIG. 8) is “NO”, and the process proceeds to step SC40 shown in FIG. In steps SC40 to SC43, the timer count is started in response to the on-operation (pressing operation) of the off-hook switch, the time for which the off-hook switch is kept pressed is counted, and the counted timer value (the time for which the press is kept pressed) It is determined whether or not a predetermined value representing is reached. That is, it is determined whether or not the off-hook switch has been operated for a long time. If the off-hook switch is not pressed for a long time, the determination result in step SC43 is “NO”, the process returns to step SC4 shown in FIG. 8, and the incoming call notification is continued until the off-hook switch is pressed for a long time.

When the off-hook switch is operated for a long time, the determination result in step SC43 shown in FIG. 12 is “YES”, the process proceeds to step SC44, and the recording / playback unit 24 is instructed to stop recording. Next, in step SC45, the network recorder is instructed to start recording so that the stopped program is recorded instead.
Note that the network recorder here refers to a video server connected from the network of the mobile phone 1 via the Internet, for example. The video server has a function of recording and reproducing a broadcast program distributed over a network or a program broadcast on the ground, for example, and is configured to record a designated program in accordance with an instruction from the mobile phone 1.

  Next, in step SC46, a confirmation sound notification is given to inform the user that a recording instruction has been given to the network recorder, and then the process returns to step SC4 shown in FIG. Thereafter, when the long-press operation of the off-hook switch is finished and the off-hook switch is released, the determination result in step SC42 shown in FIG. 11 is “YES”, and the process proceeds to step SC7 shown in FIG. Thereafter, steps SC7 to SC12 described above are executed. Then, the process proceeds to step SC47 in FIG. 12 to determine whether or not recording is in progress. In this case, since the recording is in progress, the determination result is “YES” and the process proceeds to step SC48. In step SC48, the recording / playback unit 24 is instructed to resume recording, and in the subsequent step SC49, the network recorder is instructed to stop recording to complete this processing.

  As described above, in the third embodiment, when an incoming call is received during recording, the recording / playback unit 24 is instructed to stop recording in response to a long press operation of the off-hook switch, and instead, the network recorder is configured to record the program. When the call is started after the start of recording is instructed and the call is terminated by an on-hook operation, the recording / playback unit 24 is instructed to resume recording, and the network recorder is instructed to stop recording. It is possible to do.

E. Fourth Embodiment Next, an operation of incoming call detection processing according to a fourth embodiment will be described with reference to FIGS. 10 to 11 and FIGS. 13 to 14. As in the first embodiment described above, if there is an incoming call during the execution of the main routine, the control unit 12 interrupts this process and proceeds to step SC50 shown in FIG. 13, where the TV receiver 20 is in the on state or the recording / playback unit. It is determined whether 24 is in one of the playback states. Then, in any state, the determination result is “YES”, and the process proceeds to the next step SC51 to stop the output of the broadcast reception voice or the reproduction voice in order to prioritize the incoming call of the mobile phone 1, and to step SC52. move on. On the other hand, if it is not in any state, the determination result in step SC50 is “NO”, and the flow proceeds to step SC52. In step SC52, the incoming screen is superimposed on the display unit 18. Next, in step SC53, an incoming call notification is issued for emitting a ringtone from the speaker 16, and in subsequent step SC54, incoming call processing is executed depending on whether recording is in progress. Hereinafter, the operation will be described separately for a case where recording is not performed and a case where recording is being performed.

(A) When not recorded In this case, the determination result at step SC54 is “YES”, and the process proceeds to step SC55 to determine the presence or absence of an off-hook operation. If the off-hook operation is not performed, the determination result is “NO”, and the process returns to step SC53 described above. Thus, the incoming call notification is continued until the off-hook operation is performed. When an off-hook operation is performed, the determination result in step SC55 is “YES”, and the flow advances to step SC56 to execute call processing. Next, in step SC57, it is determined whether or not the recording is in progress. In this case, since the recording is not performed, the determination result is “YES”, and the process proceeds to step SC58 to determine the presence or absence of the on-hook operation. Then, the call process is continued until the on-hook operation is performed. When the on-hook operation is performed, the determination result in step SC58 becomes “YES”, and the process proceeds to step SC59 to execute the call end process.

  When the call termination process is completed, the control unit 12 advances the process to step SC60, and erases the incoming call screen that is superimposed at the time of incoming call detection. Subsequently, in step SC61, it is determined whether the TV receiver 20 is on or the recording / playback unit 24 is in a playback state. In any state, the determination result is “YES”, the process proceeds to step SC62, and after the audio output is resumed, the process proceeds to step SC36 shown in FIG. 11 as in the second embodiment. On the other hand, if it is not in any state, the determination result in step SC61 is “NO”, and the flow proceeds to step SC36 in FIG. In step SC36 shown in FIG. 11, it is determined whether or not the recording is in progress. In this case, since the recording is not performed, the determination result is “NO”, and this processing is completed.

(B) During recording When an incoming call is detected during recording, the determination result in step SC54 (see FIG. 13) is “NO”, and as in the second embodiment described above, FIG. Proceed to step SC30. In steps SC30 to SC33, the timer count is started in response to the on-operation (pressing operation) of the off-hook switch, the time for which the off-hook switch is continuously pressed is counted, and the counted timer value (the time for which the press is kept pressed) It is determined whether or not a predetermined value representing is reached. That is, it is determined whether or not the off-hook switch has been operated for a long time. Here, if the off-hook switch is not pressed for a long time, the determination result in step SC33 is “NO”, the process returns to step SC53 shown in FIG. 13, and the incoming call notification is continued until the off-hook switch is pressed for a long time.

  When the off-hook switch is pressed for a long time, the determination result in step SC33 shown in FIG. 10 is “YES”, the process proceeds to step SC34, and the frame rate for the AV decoder 23 is changed from 24 f / s to 12 f / s. Instruct. Next, in step SC35, a confirmation sound notification for notifying the user of the frame rate change is performed, and then the process returns to step SC53 shown in FIG. Thereafter, when the long-pressing operation of the off-hook switch is finished and the off-hook switch is released, the determination result in step SC32 shown in FIG. 10 is “YES”, and the process proceeds to step SC56 shown in FIG.

  As a result, the call processing is performed in step SC56 in a state where the recording with the frame rate changed from 24 f / s to 12 f / s is continued. In step SC57, it is determined whether or not recording is in progress. In this case, since the recording is in progress, the determination result is “NO”, and the process proceeds to step SC65 shown in FIG. In steps SC65 to SC68, the frame rate is changed to any one of “24f / s”, “12f / s”, and “6f / s” in accordance with the ON operation of the UP / DOWN cursor switch. That is, when priority is given to call quality, the DOWN cursor switch is turned on to lower the frame rate, and when priority is given to recording quality, the UP cursor switch is turned on to increase the frame rate. When the frame rate up / down setting is changed, the process proceeds to step SC58 in FIG. 13 to determine whether or not an on-hook operation is performed.

  Steps SC56 to SC58 are repeated until the on-hook operation is repeated, and the call processing is continued. When the on-hook operation is performed, the determination result in step SC58 becomes “YES”, and the flow proceeds to step SC59. Thereafter, after executing the above-described steps SC59 to SC62, the process proceeds to step SC36 shown in FIG. 11 in the same manner as in the second embodiment described above to determine whether or not recording is in progress. The determination result is “YES”, and the flow proceeds to step SC37. In step SC37, the AV decoder 23 is instructed to return the frame rate from 12 f / s to 24 f / s, and this process is completed.

  As described above, in the fourth embodiment, when an incoming call is received during recording, the call is started after the frame rate for recording is reduced by half from 24 f / s to 12 f / s in response to a long press operation of the off-hook switch. If you want to prioritize the call quality during a call, lower the frame rate. If you want to prioritize the recording quality, set the frame rate to higher. When the call ends by on-hook operation, the recording frame rate is set to 12 f / s. Therefore, it is possible to record while maintaining the call quality or to make a call while maintaining the recording quality. In the present embodiment, only the frame rate is changed. However, instead of this, the image size may be changed in accordance with the change of the frame rate.
