That is, when there is a recording instruction from the CPU 100, the recording / reproducing unit 111 compresses and encodes the reception signal output from the television broadcast / radio broadcast receiving unit 104 and records it in the recording data storage unit 102 a of the RAM 102. On the other hand, when there is a reproduction instruction from the CPU 100, the reproduction data instructed to be reproduced is read from the recording data storage unit 102 a of the RAM 102, and reproduction data obtained by decompression decoding is output to the CPU 100. The recording / playback unit 111 also has a function of time-shift playback (chase playback) that performs playback while recording.

B. Action
Next, the operation of the mobile phone 10 having the above configuration will be described. In the following, after describing the operation of the “main routine” executed by the CPU 100 of the mobile phone 10, “output processing”, “earphone operable processing”, “earphone inoperable processing”, “monitor” called from this main routine Each operation of the “operation possible process”, “monitor operation impossible process”, and “timeout process” will be described sequentially.

(1) Operation of Main Routine FIGS. 3 to 4 are flowcharts showing the operation of the main routine executed by the CPU 100. FIG. When the mobile phone 10 is powered on by the user's power-on operation, the CPU 100 executes the main routine shown in FIG. 3 and advances the process to step SA1. In step SA1, a position registration control sequence is executed to perform position registration on the network side, and then a standby process for entering a standby state is executed.

  Subsequently, in steps SA2 to SA5 shown in FIG. 3 and steps SA6 to SA10 shown in FIG. 8, “television / radio output operation”, “earphone inoperability → operation possible detection”, “earphone operation inability → inoperability detection”, Determines whether there are events of “monitoring inoperable → operable detection”, “monitoring operational → inoperable detection”, “delay timer predetermined time elapsed”, “incoming call detection”, “power off operation”, and “other operation” events . If these events do not occur, the determination results in steps SA2 to SA10 are all “NO”, and the apparatus stands by in a standby state. On the other hand, when any of the above events occurs in the standby state, processing corresponding to the generated event is executed. Hereinafter, the operation for each event will be described.

a. When a TV / Radio Output Operation is Performed When an operation event of a TV / radio output switch (not shown) provided in the operation unit 107 is detected, the determination result in step SA2 is “YES”, and the process proceeds to step SA11 for output. Execute the process. In the output process, as described later, based on connection state data and wearing state data generated by the earphone connecting unit 109, it is determined whether the earphone is connected / not connected and whether the user is wearing / not wearing the earphone, and being connected to the earphone connecting unit 109. When the earphone 20 is removed from the user and is not worn, the external output of the audio data being listened to is stopped by broadcasting and output from the main body (audio signal processing unit 105), and the audio data being listened to is The recording / reproducing unit 111 automatically enters the automatic recording state.

Further, in the output process, the monitor connection / non-connection and the monitor power-on / non-power-on are determined based on the connection state data and the power state data generated by the monitor connection unit 110, and the external monitor connected to the monitor connection unit 110 is determined. If the power is not turned on and the power is not turned on, the external output of the video data being viewed is stopped by receiving the broadcast, and is displayed and output on the main body (display unit 106), and the video data / The automatic recording state in which the recording / playback unit 111 automatically records the television audio data is set. When such output processing is completed, the CPU 100 returns the processing to step SA2 and returns to the standby state.

b. Earphone inoperability → When operation is detected
When the earphone connecting unit 109 generates connection state data indicating that the earphone is connected to the earphone 20 and wearing state data indicating that the user is wearing the earphone, the CPU 100 detects an earphone inoperable → operation possible event. Then, the determination result in step SA3 is “YES”, and the process proceeds to step SA12 to execute the earphone operable process.

In the earphone operation enabling process, as will be described later, when the earphone operation is enabled, the audio data is transmitted only to the earphone 20 side and the external monitor 30 is in an operation state if the earphone operation is enabled and the broadcast is being received. Then, the video data is output only to the external monitor 30 side. If the external monitor 30 is in a non-operating state, the external output of the video data is stopped and displayed on the main body (display unit 106).

On the other hand, if it is in the automatic recording state when the earphone operation becomes possible, the broadcast content that has been automatically recorded when the earphone is not attached is chased and reproduced, and the reproduced audio data is only transmitted to the earphone 20 side. Video data to be transmitted and reproduced is output only to the external monitor 30 when the external monitor 30 is in an operating state, and is displayed on the main body (display unit 106) when the external monitor 30 is in an inactive state. When the earphone operable process is completed, the CPU 100 returns the process to step SA2 and returns to the standby state.

c. Earphone operation possible → When inoperability is detected
When the earphone connection unit 109 generates connection state data indicating that the earphone 20 is not connected, or when wearing state data indicating that the user is not wearing the earphone while the earphone is connected, the CPU 100 can operate the earphone. Detect events. Then, the determination result in step SA4 is “YES”, and the process proceeds to step SA13 to execute the earphone operation disabled process.

In the earphone inoperability processing, as will be described later, if the earphone operation is disabled and the broadcast is being received, and the earphone connection period has reached a predetermined time, the broadcast content being received is recorded / reproduced by the recording / reproducing unit 111. At the same time as the automatic recording state to be automatically recorded, the TV audio data (or radio audio data) output from the TV broadcast / radio broadcast receiving unit 104 is output to the main body (output from the audio signal processing unit 105) and video For data, both external output (monitor connection unit 110) and main unit output (display unit 106) are stopped. When the earphone inoperability process is completed, the CPU 100 returns the process to step SA2 and returns to the standby state.

d. When monitor operation is disabled → operation is detected
When the monitor connection unit 110 generates connection state data indicating that the external monitor 30 is connected and power state data indicating that the connected external monitor 30 is powered on, the CPU 100 cannot perform the monitor operation. → Detect an operable detection event. Then, the determination result in step SA5 is “YES”, and the process proceeds to step SA14 to execute the monitor operation enabling process.

In the monitor operation enabling process, as will be described later, when the monitor operation is enabled, if it is not in the automatic recording state and the broadcast is being received, the video data is output only to the external monitor 30 side and the earphone 20 is connected. If it is in the middle, the audio data is transmitted only to the earphone 20 side. On the other hand, if the earphone 20 is not connected, it is output from the main body (audio signal processing unit 105).

  On the other hand, if the automatic recording state is enabled when the monitor operation is enabled, the broadcast content that has started automatic recording when the monitor is inactive is chased and reproduced, and the reproduced video data is transferred to the external monitor 30 side. If the earphone 20 is operable, the audio data to be reproduced is output only to the earphone 20 side. If the earphone 20 is inoperable, the audio data is output from the main body (audio signal processing unit 105). When such a monitor operable process is completed, the CPU 100 returns the process to step SA2 and returns to the standby state.

e. Monitor operation possible → When operation is detected
When the monitor connection unit 110 generates connection state data indicating that the external monitor 30 is not connected, or when power supply state data indicating non-power-on is generated while the external monitor is connected, the CPU 100 cannot perform the monitor operation. → Detect an operable detection event. Then, the determination result in step SA6 shown in FIG. 4 is “YES”, the process proceeds to step SA15, and the monitor operation disable process is executed.

As will be described later, in the monitor operation disabling process, when the monitor operation is disabled, the broadcast is being received, and if the monitor operation period length has reached a predetermined time, the broadcast content being received is recorded and reproduced. 111 is set to an automatic recording state for automatic recording in 111, the external output and the main body output of the TV audio data (or radio audio data) output from the TV broadcast / radio broadcast receiving unit 104 are stopped, and the video data is The display is output from the main body (display unit 106). When such a monitor operation disabling process is completed, the CPU 100 returns the process to step SA2 shown in FIG. 3 to return to the standby state.

f. When a predetermined time has elapsed
When either the earphone inoperable period timed by the earphone out timer (described later) or the monitor inoperable period timed by the monitor out timer (described later) passes a predetermined time, the CPU 100 detects a time-out event. Then, the determination result in step SA7 shown in FIG. 4 is “YES”, the process proceeds to step SA16, and the time-out process is executed.

In the time-out process, as described later, when the time-out by the earphone out-of-timer (or the time-out by the out-of-monitor timer) occurs, the recording / playback unit 111 stops the recording of the automatically recorded broadcast content when it is in the automatic recording state. After the deletion, the earphone recording flag (or monitor recording flag) is reset to zero to cancel the automatic recording state, and the earphone removal timer (or monitor removal timer) is ended. When the timeout process is completed, the CPU 100 returns the process to step SA2 shown in FIG. 3 to return to the standby state.

g. When an incoming call is detected
When an incoming call is detected, the determination result in step SA8 is “YES”, and the process advances to step SA17 to execute incoming call processing. In the incoming call processing, an incoming call notification is performed, and when an off-hook operation is performed during the incoming call notification, a call is started by connecting the line to the calling side, and a call process for disconnecting the line is executed in response to the on-hook operation. When the incoming call process is completed, the CPU 100 returns the process to step SA2 shown in FIG. 3 to return to the standby state.

h. When the power is turned off
When the power-off operation is performed, the determination result in step SA9 is “YES”, the process proceeds to step SA18, and after executing the power-off process, this process is completed.

i. When other operations are performed
When other operations other than those described above are performed, the determination result of step SA10 is “YES”, and the process proceeds to step SA19 to execute other processes. Other processing refers to processing such as mail creation and mail transmission. Then, after the other processes are executed, the process returns to step SA2 to return to the standby state.

(2) Operation of output processing
Next, the operation of the output process will be described with reference to FIGS. 5 to 6 are flowcharts showing the operation of the output process. FIGS. 7 to 10 are an earphone output control A process, an earphone output control B process, a monitor output control A process, and a monitor output control B called from the output process. It is a flowchart which shows each operation | movement of a process.

When this process is executed through step SA11 (see FIG. 3) of the main routine described above, the CPU 100 advances the process to step SB1 shown in FIG. In step SB1, in response to the operation of the television / radio output switch, the television broadcast / radio broadcast receiving unit 104 is instructed to start the television broadcast reception (or radio broadcast reception).

Subsequently, in steps SB2 to SB10, processing corresponding to the earphone connection / non-connection and the user's earphone attachment / non-attachment is executed. In steps SB11 to SB19, the monitor connection / non-connection and the monitor power-on / non-power-on are performed. The process according to is executed. In the following, description of the operation will be divided into “in the case of earphone connection”, “in the case of no earphone connection”, “in the case of monitor connection”, and “in the case of no monitor connection”.

<For earphone connection>
In step SB2, it is determined based on the connection state data generated by the earphone connecting unit 109 whether or not the earphone is being connected. If the earphone is connected, the determination result in step SB2 is “YES”, and the process proceeds to step SB3. In step SB3, whether or not the user wears the earphone is determined based on the wearing state data generated by the earphone connecting unit 109. Hereinafter, the operation will be described separately for the case of wearing the earphone and the case of not wearing the earphone.

a. When wearing earphones
If the user wears the earphone 20, the determination result in step SB3 is “YES”, and the earphone output control A process is executed via step SB4. When the earphone output control A process is executed, the CPU 100 advances the process to step SC1 shown in FIG. 7 and outputs audio data to the outside. That is, when receiving a television broadcast, the television sound data received and output by the television broadcast / radio broadcast receiving unit 104 is supplied to the earphone connecting unit 109. When receiving a radio broadcast, the radio sound data received and output by the television broadcast / radio broadcast receiving unit 104 is supplied to the earphone connecting unit 109. As a result, the earphone connection unit 109 wirelessly transmits the TV sound data (or radio sound data) supplied from the CPU 100 to the earphone 20. Next, in step SC2, the TV audio / radio broadcast receiving unit 104 receives and outputs the TV audio data (or radio audio data) is not output to the audio signal processing unit 105, but the main output of the audio data is stopped and this process is performed. Finish.

  Thus, when the earphone output control A process for transmitting the TV sound data (or radio sound data) only to the earphone 20 side is completed, the CPU 100 proceeds to the process at step SB5 shown in FIG. 5 and starts the earphone connection timer. The process proceeds to step SB11 (see FIG. 6) described later. When the earphone connection timer is activated, the CPU 100 starts to measure the earphone connection period (period in which the earphone connection state continues) in an interrupt process (not shown) executed at predetermined intervals.

b. When not wearing earphones
If the user does not wear the earphone 20, the determination result in step SB3 is “NO”, and the earphone output control B process is executed via step SB6. When the earphone output control B process is executed, the CPU 100 proceeds to step SD1 shown in FIG. 8, and the TV sound data (or radio sound data) received and output by the TV broadcast / radio broadcast receiver 104 is connected to the earphone connector. The external output of audio data is stopped without being supplied to 109.

Next, in step SD2, television audio data (or radio audio data) received and output by the television broadcast / radio broadcast receiving unit 104 is supplied to the audio signal processing unit 105 and output from the main body. Thus, the audio signal processing unit 105 performs D / A conversion on the TV audio data (or radio audio data) supplied from the CPU 100, and then amplifies and emits the sound from the speaker SP.

  When the earphone output control B process is completed, the CPU 100 advances the process to step SB7 shown in FIG. In step SB7, the recording / playback unit 111 is instructed to record a reception signal (video data / television audio data when receiving television, radio audio data when receiving radio) output from the television / radio broadcast receiving unit 104.

Next, in step SB8, the received signal compressed and encoded by the recording / reproducing unit 111 in accordance with the recording instruction in step SB7 is recorded in the recording data storage unit 102a of the RAM 102. In step SB9, after setting the earphone recording flag to “1”, the process proceeds to step SB11 shown in FIG. Note that setting “1” to the earphone recording flag indicates that the earphone is disconnected (the earphone is not attached) and the broadcast content being received is automatically recorded.

<Without earphone connection>
On the other hand, when the earphone is not connected, the determination result of step SB2 described above is “NO”, and the earphone output control B process shown in FIG. 8 is executed via step SB10. In the earphone output control B process, as described above, external output of audio data is stopped and output from the main body (audio signal processing unit 105). Thereafter, the process proceeds to step SB11 illustrated in FIG.

<For monitor connection>
In step SB11 shown in FIG. 6, it is determined whether or not the monitor is connected based on the connection state data generated by the monitor connection unit 110. If the monitor is connected, the determination result in step SB11 is “YES”, and the process proceeds to step SB12. In step SB12, based on the power state data generated by the monitor connection unit 110, it is determined whether or not the operation switch of the external monitor 30 is turned on, that is, whether the power of the external monitor 30 is on or not. Hereinafter, the operation will be described separately when the monitor is in operation and when the monitor is not in operation.

a. When the monitor power is on
If the monitor power is on, the determination result in step SB12 is “YES”, and the monitor output control A process is executed via step SB13. When the monitor output control A process is executed, the CPU 100 advances the process to step SE1 shown in FIG. 9, and outputs the video data to the outside. That is, when receiving a television broadcast, the video data received and output by the television broadcast / radio broadcast receiving unit 104 is supplied to the monitor connection unit 110. Thereby, the monitor connection unit 110 outputs the video data supplied from the CPU 100 to the external monitor 30. Next, in step SE2, the video data received and output by the television broadcast / radio broadcast receiving unit 104 is not supplied to the display unit 106, and the main output of the video data is stopped.

  When the monitor output control A process is completed, the CPU 100 proceeds to step SB14 shown in FIG. 6, starts the monitor connection timer, and ends the process. When the monitor connection timer is activated, the CPU 100 starts to measure the monitor connection period (the period during which the monitor connection state is continued) in an interrupt process (not shown) executed at predetermined intervals.

b. When the monitor is not powered
If the monitor is not powered on, the determination result at step SB12 is “NO”, and the monitor output control B process is executed via step SB15. When the monitor output control B process is executed, the CPU 100 advances the process to step SF1 shown in FIG. 10 and does not supply the video data output from the television broadcast / radio broadcast receiving unit 104 to the monitor connection unit 110. Stop external output of. Next, in step SF2, the video data output from the television broadcast / radio broadcast receiving unit 104 is supplied to the display unit 106 and output from the main body. Thereby, the display unit 106 displays the video data supplied from the CPU 100 on the screen.

  When such monitor output control B processing is completed, the CPU 100 proceeds to step SB16 shown in FIG. In step SB16, the recording / reproducing unit 111 is instructed to record the video data / television audio data received and output by the television / radio broadcast receiving unit 104. Next, in step SB17, the video data / television audio data compression-encoded by the recording / reproducing unit 111 in accordance with the recording instruction in step SB16 is recorded in the recording data storage unit 102a of the RAM 102. In step SB18, the monitor recording flag is set to “1”, and the present process ends. Note that setting the monitor recording flag to “1” indicates that the broadcast content being received is automatically recorded when the monitor is not powered on.

  In the case where the automatic recording state is already in effect due to the earphone not being attached, the automatic recording process (the above-described steps SB16 to SB17) when the monitor is not turned on is invalid and is omitted.

<When the monitor is not connected>
On the other hand, if the monitor is not connected, the determination result in step SB11 is “NO”, and the monitor output control B process shown in FIG. 10 is executed via step SB19. In the monitor output control B process, as described above, the external output of the video data is stopped, the display is output from the main body (display unit 106), and the output process is finished.

  As described above, in the output processing, based on the connection state data and the wearing state data generated by the earphone connecting unit 109, it is determined whether the earphone is connected / not connected and whether the user is wearing / not wearing the earphone, and the earphone connecting unit 109 is currently connected. When the earphone 20 is detached from the user and is not attached, external output of audio data during broadcast reception is stopped and output from the main body (audio signal processing unit 105), and the audio data is automatically recorded.

Further, in the output process, the monitor connection / non-connection and the monitor power-on / non-power-on are determined based on the connection state data and the power state data generated by the monitor connection unit 110, and the external monitor connected to the monitor connection unit 110 is determined. If 30 is not powered on and is not powered on, the external output of video data during broadcast reception is stopped and displayed on the main body (display unit 106), and video data / TV audio data during broadcast reception is also displayed. Is automatically recorded.

(3) Operation of earphone operable processing
Next, the operation of the earphone operable process will be described with reference to FIGS. 11 is a flowchart showing the operation of the earphone operable process, and FIG. 12 is a flowchart showing the operation of the monitor output control C process called from the earphone operable process.

When the earphone operable process is executed via step SA12 (see FIG. 3) of the main routine described above, the CPU 100 advances the process to step SG1 shown in FIG. In step SG1, it is determined whether or not the earphone recording flag is “0”, that is, whether or not it is an automatic recording state in which the content of the broadcast being received is automatically recorded due to the occurrence of earphone disconnection (no earphone attachment). Hereinafter, the operation will be described separately for the case of not being in the automatic recording state (when the earphone recording flag is “0”) and the case of being in the automatic recording state (when the earphone recording flag is “1”).

a. When not in automatic recording state
When the earphone 20 is connected to the earphone connection unit 109 and is attached to the user and the earphone operation is enabled, if the automatic recording state is not established, the determination result in step SG1 is “YES” and the process proceeds to step SG2. . In step SG2, it is determined whether the television / radio broadcast receiving unit 104 is receiving a broadcast. If the broadcast is not being received, the determination result is “NO”, and this process is completed. If the broadcast is being received, the determination result in step SG2 is “YES”, and the above-described earphone is received via step SG3. Output control A processing (see FIG. 7) is executed, and audio data (television audio data or radio audio data) is sent only to the earphone 20 side.

  Next, in step SG4, monitor output control C processing is executed. When the monitor output control C process is executed, the CPU 100 advances the process to step SH1 shown in FIG. 12, and the external monitor 30 is operable based on the connection state data and the power state data generated by the monitor connection unit 110. Whether or not it is connected to the monitor connection unit 110 and whether or not the power is turned on is determined. If the external monitor 30 is in the operating state (connected to the monitor connection unit 110 and powered on), the determination result is “YES”, the process proceeds to step SH2, and the monitor output control A described above is performed. Processing (see FIG. 9) is executed, and video data is output only to the external monitor 30.

On the other hand, if the external monitor 30 is in a non-operating state (not connected to the monitor connection unit 110 or not powered on), the determination result in step SH1 is “NO”. Proceeding to SH3, the monitor output control B process (see FIG. 10) described above is executed, the external output of the video data is stopped, and the main body (display unit 106) displays it. Thereafter, the process proceeds to step SG5 shown in FIG. 11, the earphone connection timer is activated, and the earphone operable process is completed. It should be noted that the earphone connection period starts to be measured by the activation of the earphone connection timer.

As described above, when the earphone operation is enabled, if the recording is not in the automatic recording state and the broadcast is being received, the audio data is transmitted only to the earphone 20 side. When the external monitor 30 is in a non-operating state, the external output of the video data is stopped and displayed on the main body (display unit 106).

b. For automatic recording
When the earphone 20 is connected to the earphone connection unit 109 and is attached to the user and the earphone operation is enabled, the judgment result of the above step SG1 (see FIG. 11) is “NO” when it is in the automatic recording state. The process proceeds to step SG6. In step SG6, the recording / reproducing unit 111 is instructed to reproduce the recording data automatically recorded in the recording data storage unit 102a of the RAM 102.

  Next, in step SG7, the recording / reproducing unit 111 is instructed to perform high-speed reproduction (chase reproduction) of the broadcast content (recorded data) instructed to be reproduced in step SG6. Then, the earphone output control A process (see FIG. 7) described above is executed via step SG8, and the audio data (television audio data or radio audio data) that the recording / reproducing unit 111 reproduces at high speed (chase reproduction) is transmitted to the earphone 20 side. Only send to. As a result, the broadcast content that has started to be automatically recorded at the time when the earphone is not worn is chased and reproduced.

  Subsequently, in step SG9, if the external monitor 30 is in an operating state, video data that the recording / playback unit 111 performs high-speed playback (chasing playback) is output only to the external monitor 30, and if the external monitor 30 is in a non-operating state, video is output. The monitor output control C process (see FIG. 12) for stopping the external output of data and causing the main body (display unit 106) to output the display is executed.

Next, in step SG10, the earphone recording flag is reset to zero to cancel the automatic recording state. In step SG11, the earphone disconnect timer is terminated. After the high speed reproduction is completed, the process proceeds to step SG2. The earphone disconnect timer is a timer that is activated when the earphone operation is disabled, and measures the earphone inoperable period.

  As described above, when the earphone operation is enabled, if the automatic recording state is established, the broadcast content that has been automatically recorded at the time when the earphone is not operated is chased and reproduced. The video data to be transmitted only to the side is output only to the external monitor 30 if the external monitor 30 is in an operating state, and is displayed on the main body (display unit 106) if the external monitor 30 is not operating. It has become.

  In step SG4 and step SG9 described above, when the external monitor 30 is operating, the video data is output only to the external monitor 30, and when the external monitor 30 is not operating, the external output of the video data is stopped and the main body (display The monitor output control C process (see FIG. 12) for display output by the unit 106) is executed. However, the present invention is not limited to this, and step SG4 and step SG9 may be omitted and the video data output destination may not be changed. I do not care.

(4) Earphone inoperability processing operation
Next, the operation of the earphone inoperability process will be described with reference to FIG. FIG. 13 is a flowchart showing the operation of the earphone inoperability process. When the earphone disabling process is executed through step SA13 (see FIG. 3) of the main routine described above, the CPU 100 proceeds to step SJ1 shown in FIG. 13, and the television broadcast / radio broadcast receiving unit 104 receives the broadcast. Determine if it is in the middle. If the broadcast is not being received, the determination result is “NO”, the process proceeds to step SJ11, the earphone connection timer is terminated, and this process is terminated. Note that the earphone connection timer is completed by ending the earphone connection timer.

  On the other hand, if the broadcast is being received, the determination result in step SJ1 is “YES”, and the process proceeds to step SJ2. In step SJ2, it is determined whether or not the earphone connection period timed by the earphone connection timer has reached a predetermined time. If the earphone connection period has reached the predetermined time, the determination result is “YES”, the process proceeds to step SJ3, and the earphone disconnect timer is started. Subsequently, in step SJ4, the recording / reproducing unit 111 records the reception signal (video data / television audio data when receiving television, radio audio data when receiving radio) output from the television / radio broadcast receiving unit 104. Instruct.

In step SJ5, the received signal compressed and encoded by the recording / reproducing unit 111 in accordance with the recording instruction in step SJ4 is recorded in the recording data storage unit 102a of the RAM 102. Next, in step SJ6, the earphone recording flag is set to “1” to indicate that the automatic recording state is set.

  Thereafter, in steps SJ7 to SJ8, the external output of the audio data is stopped without supplying the TV audio data (or radio audio data) received and output from the TV broadcast / radio broadcast receiving unit 104 to the earphone connecting unit 109. Then, the TV sound data (or radio sound data) is supplied to the sound signal processing unit 105 and output from the main body. Subsequently, in steps SJ9 to SJ10, the video data received and output from the television broadcast / radio broadcast receiving unit 104 is not supplied to the monitor connecting unit 110 or the display unit 106. Stop output. Then, the process proceeds to step SJ11, the earphone connection timer is terminated, and the present process is terminated.

  On the other hand, if the earphone connection period does not reach the predetermined time, for example, when the earphone 20 and the earphone connection unit 109 are connected for a short time due to a user's erroneous operation, the determination result of step SJ2 described above is “NO”. Thus, the processes after step SJ7 are executed to stop the external output of the audio data to output the main body and to stop the external output / main body output of the video data. Thereafter, the earphone connection timer is terminated and the present process is terminated.

  As described above, in the earphone inoperability processing, when the earphone operation is disabled and the broadcast is being received and the earphone connection period has reached a predetermined time, the broadcast content being received is automatically recorded. TV audio data (or radio audio data) output from the TV broadcast / radio broadcast receiving unit 104 is supplied to the audio signal processing unit 105 and output to the main body, and video data is output. External output and main unit output are stopped.

In the above-described earphone disabling process, the audio data is supplied to the audio signal processing unit 105 and output to the main body in step SJ8. However, the present invention is not limited to this, and the process of step SJ8 is omitted. It does not matter even if the main body output is not performed.

Further, in steps SJ9 to SJ10, the external output / main body output of the video data is stopped. However, the present invention is not limited to this, and the processing of steps SJ9 to SJ10 may be omitted and the output destination of the video data may not be changed. .

(5) Operation of monitor enable processing
Next, the operation of the monitor operation enabling process will be described with reference to FIGS. FIG. 14 is a flowchart showing the operation of the monitor operable process, and FIG. 15 is a flowchart showing the operation of the earphone output control C process called from the monitor operable process.

When the monitor operation enabling process is executed through step SA14 (see FIG. 3) of the main routine described above, the CPU 100 advances the process to step SK1 shown in FIG. 14 and determines whether or not the monitor recording flag is “0”. That is, it is determined whether or not the monitor recording operation is in an automatic recording state in which the broadcast content being received is automatically recorded. Hereinafter, the operation will be described separately for the case of not being in the automatic recording state (when the monitor recording flag is “0”) and the case of being in the automatic recording state (when the monitor recording flag is “1”).

a. When not in automatic recording state
If the external monitor 30 connected to the monitor connection unit 110 is not in the automatic recording state when it is in the operating state, the determination result in step SK1 is “YES”, and the process proceeds to step SK2. In step SK2, it is determined whether the television broadcast / radio broadcast receiver 104 is receiving a broadcast. If the broadcast is not being received, the determination result is “NO”, and this processing is completed. If the broadcast is being received, the determination result in step SK2 is “YES”, and the above-described monitor is received via step SK3. Output control A processing (see FIG. 9) is executed, and video data is output only to the external monitor 30 side.

  Next, in step SK4, an earphone output control C process is executed. When the earphone output control C process is executed, the CPU 100 advances the process to step SL1 shown in FIG. 15, and whether the earphone 20 is operable based on the connection state data and the wearing state data generated by the earphone connection unit 109. Judge whether or not. If the earphone 20 is operable (connected to the earphone connection unit 109 and attached to the user), the determination result is “YES”, the process proceeds to step SL2, and the above-described earphone output control A process (see FIG. 7) is performed. The voice data is transmitted only to the earphone 20 side.

On the other hand, if the earphone 20 is inoperable (not connected to the earphone connector 109 or not attached to the user), the determination result in step SL1 is “NO”, the process proceeds to step SL3, and the above-described earphone output is performed. Control B processing (see FIG. 8) is executed, external output of audio data is stopped, and output from the main body (audio signal processing unit 105). Thereafter, the process proceeds to step SK5 shown in FIG. 14, and the monitor connection timer is started to finish the monitor operation enabling process. When the monitor connection timer is activated, the CPU 100 starts to measure the monitor operation period.

In this way, when the monitor operation is enabled, if it is not in the automatic recording state and the broadcast is being received, the video data is output only to the external monitor 30 side, and if the earphone 20 is connected, the earphone 20 side If the earphone 20 is not connected, the audio data is output from the main body (audio signal processing unit 105).

b. For automatic recording
If it is in the automatic recording state when the monitoring operation is enabled, the determination result in step SK1 (see FIG. 14) is “NO”, and the flow proceeds to step SK6. In step SK6, the recording / reproducing unit 111 is instructed to reproduce the recording data automatically recorded in the recording data storage unit 102a of the RAM 102.

Next, in step SK7, the recording / reproducing unit 111 is instructed to perform high-speed reproduction (chase reproduction) of the broadcast content (recorded data) instructed to be reproduced in step SK6. Then, the above-described monitor output control A process (see FIG. 9) is executed via step SK8, and the video data that the recording / reproducing unit 111 reproduces at high speed (follow-up reproduction) is output only to the external monitor 30 side. As a result, the follow-up playback of the broadcast content that has started to be automatically recorded at the time when the monitor is not operated is performed.

  Subsequently, in step SK9, if the earphone 20 is operable, the recording / playback unit 111 transmits the audio data to be reproduced at high speed only to the earphone 20 side, and if the earphone 20 is inoperable, the external output of the audio data is stopped. The earphone output control C process (see FIG. 15) to be output from the main body (audio signal processing unit 105) is executed. In step SK10, the monitor recording flag is reset to zero to cancel the automatic recording state. In step SK11, the non-monitoring timer is terminated. After the high speed reproduction is completed, the process proceeds to step SK2. Note that the time of the monitor inoperable period is completed by the end of the out-of-monitor timer.

  As described above, if the automatic recording state is enabled when the monitor operation is enabled, the broadcast content that has been automatically recorded when the monitor is inactive is chased and reproduced, and the reproduced video data is externally monitored. If the earphone 20 is operable, the sound data that is output only to the 30 side is output only to the earphone 20 side if the earphone 20 is operable, and is output from the main body (audio signal processing unit 105) if the earphone 20 is inoperable. .

In step SK4 and step SK9 described above, when the external monitor 30 is operating, the video data is output only to the external monitor 30, and when the external monitor 30 is not operating, the external output of the video data is stopped and the main body (display) is displayed. The monitor output control C process (see FIG. 12) for display output by the unit 106) is executed. However, the present invention is not limited to this, and step SG4 and step SG9 may be omitted and the video data output destination may not be changed. I do not care.

(6) Operation of monitor disabling process
Next, the operation of the monitor operation disabling process will be described with reference to FIG. FIG. 16 is a flowchart showing the operation of the monitor operation disabling process. When the monitor operation disable process is executed via step SA15 (see FIG. 4) of the main routine described above, the CPU 100 proceeds to step SM1 shown in FIG. 15, and the television / radio broadcast receiver 104 receives the broadcast. Determine if it is in the middle. If the broadcast is not being received, the determination result is “NO”, the process proceeds to step SM11, the monitor connection timer is terminated, and this process is terminated. Note that the monitoring operation period is completed when the monitor connection timer expires.

  On the other hand, if the broadcast is being received, the determination result in step SM1 is “YES”, and the process proceeds to step SM2. In step SM2, it is determined whether or not the monitor operation period timed by the monitor connection timer has reached a predetermined time. If the monitor operation period has reached the predetermined time, the determination result is “YES”, the process proceeds to step SM3, and the off-monitor timer is started. Subsequently, in step SM4, the recording / reproducing unit 111 records the reception signal (video data / television audio data when receiving television, radio audio data when receiving radio) output from the television / radio broadcast receiving unit 104. Instruct.

In step SM5, the reception signal compression-encoded by the recording / reproducing unit 111 in accordance with the recording instruction in step SM4 is recorded in the recording data storage unit 102a of the RAM 102. Next, in step SM6, the monitor recording flag is set to “1” to indicate that the automatic recording state has been entered.

  Thereafter, in steps SM7 to SM8, external output and main body output of television audio data (or radio audio data) received and output from the television broadcast / radio broadcast receiving unit 104 are stopped. Subsequently, in steps SM9 to SM10, the video data received and output from the television broadcast / radio broadcast receiving unit 104 is not output to the monitor connection unit 110, and the external output of the video data is stopped, while the video data is displayed on the display unit 106. To display on the main body. Then, the process proceeds to step SM11, where the monitor connection timer is terminated and the present process is terminated.

  On the other hand, for example, it is assumed that the external monitor 30 is powered on for a short period of time due to a user's erroneous operation and is in an operating state. In such a case, since the monitoring operation period does not reach the predetermined time, the determination result in step SM2 described above becomes “NO”, the processing after step SM7 is executed, and the external output of audio data and the main body output are stopped. At the same time, after the video data is displayed and output on the main body, the monitor connection timer is terminated and the present process is terminated.

  As described above, in the monitor operation disabling process, when the monitor operation is disabled and the broadcast is being received and the monitor operation period has reached a predetermined time, the broadcast content being received is automatically recorded. The external recording and the main body output of the TV audio data (or radio audio data) received and output from the TV broadcast / radio broadcast receiving unit 104 are stopped, and the main body (display unit 106) ) Display output.

In the above-described monitor inoperability process, the audio data is supplied to the audio signal processing unit 105 and output to the main body in step SM8. However, the present invention is not limited to this, and the process of step SM8 is omitted. It does not matter even if the main body output is not performed.

In steps SM9 to SM10, the external output / main body output of the video data is stopped. However, the present invention is not limited to this, and the processing of steps SM9 to SM10 may be omitted and the output destination of the video data may not be changed. .

(7) Operation of timeout processing
Next, the operation of the timeout process will be described with reference to FIG. FIG. 17 is a flowchart illustrating an operation of a timeout process executed by the CPU 100. When the time-out process is executed via step SA16 (see FIG. 4) of the main routine described above, the CPU 100 proceeds to step SN1 shown in FIG. 17 and determines whether or not the time-out is due to the earphone removal timer. . The operation will be described separately for the case of timeout due to the earphone loss timer and the case of timeout due to the monitor loss timer.

a. In the case of timeout due to the earphone disconnection timer If the earphone inoperability period timed by the earphone disconnection timer exceeds the predetermined time and times out, the determination result in step SN1 is “YES”, and the process proceeds to step SN2. In step SN2, it is determined whether or not the earphone recording flag is “1”, that is, the automatic recording state. If it is not the automatic recording state, the determination result is “NO”, the process proceeds to step SN8, the earphone removal timer is terminated, and the present process is terminated.

  On the other hand, if it is in the automatic recording state, the determination result in step SN2 is “YES”, and the process proceeds to step SN3. In steps SN3 to SN4, the recording / playback unit 111 is instructed to stop recording, and writing to the recording data storage unit 102a of the RAM 102 is prohibited to stop recording of broadcast contents. Next, in steps SN5 to SN6, the recording / playback unit 111 is instructed to delete the broadcast content automatically recorded, and the broadcast content to be deleted is deleted from the recording data storage unit 102a of the RAM 102.

As a result, the broadcast content automatically recorded during the earphone inoperable period is considered invalid due to a timeout and deleted. That is, the broadcast content automatically recorded when the user intentionally disconnects or does not wear the earphone is automatically deleted when the earphone disconnect timer times out. Thereafter, the process proceeds to step SN7, where the earphone recording flag is reset to zero to cancel the automatic recording state. Then, the process proceeds to step SN8, the timer count of the earphone removal timer is ended, and this process is finished.

b. In the case of time-out due to the out-of-monitor timer When the monitor inoperable period timed out by the out-of-monitor timer exceeds a predetermined time and time-out occurs, the determination result in step SN1 becomes “NO”, and the process proceeds to step SN9. In step SN9, it is determined whether or not the monitor recording flag is “1”, that is, whether or not the automatic recording state is set. If it is not under the automatic recording state, the determination result is “NO”, the process proceeds to step SN15, the monitor off timer is ended, and the present process is terminated.

  On the other hand, if it is in the automatic recording state, the determination result in step SN9 is “YES” and the process proceeds to step SN10. In steps SN10 to SN11, the recording / playback unit 111 is instructed to stop recording, and writing to the recording data storage unit 102a of the RAM 102 is prohibited to stop recording of broadcast contents. Next, in steps SN12 to SN13, the recording / playback unit 111 is instructed to delete the broadcast content automatically recorded, and the broadcast content to be deleted is deleted from the recording data storage unit 102a of the RAM 102.

As a result, the broadcast content automatically recorded during the monitor inoperable period is considered invalid due to a timeout and is deleted. That is, the broadcast content automatically recorded when the user intentionally disconnects the monitor or does not turn on the power is automatically deleted when a timeout occurs due to the monitor off timer. Thereafter, the process proceeds to step SN14, and the monitor recording flag is reset to zero to cancel the automatic recording state. And it progresses to step SN15, an earphone removal timer is complete | finished, and this process is complete | finished.

Thus, in the time-out process, when a time-out by the earphone out-of-timer (or time-out by the out-of-monitor timer) occurs, if the recording state is the automatic recording state, the recording / reproducing unit 111 stops recording and deletes the automatically recorded broadcast content. After that, the earphone recording flag (or monitor recording flag) is reset to zero to cancel the automatic recording state, and the earphone disconnection timer (or monitor disconnection timer) is ended.

  As described above, in the first embodiment, the earphone 20 is not connected during broadcast reception based on the connection / non-connection state of the earphone 20 and the user wearing / non-wearing state determined from the signal output from the earphone 20. When it is detected that the user is in a state of wearing or not wearing a user, an automatic recording state starts to automatically record the broadcast (audio data) being received, after which the earphone 20 is connected and returned to the user wearing state, Since broadcasts during automatic recording are time-shifted (chased playback), it is possible to prevent the broadcast contents being listened to from being missed.

  In the first embodiment, the external monitor 30 is connected during broadcast reception based on the connection / non-connection state of the external monitor 30 and the monitor power-on / non-power-on state determined from the signal output by the external monitor 30. When it is detected that it is in a non-connected state or a non-powered-on state, it enters an automatic recording state for recording the broadcast (video data / audio data) being received, and then the external monitor 30 is connected and turned on. Upon return, time-shifted playback (chase playback) of the automatically recorded broadcast (video data / audio data) is performed, so that it is possible to prevent the broadcast content being watched from being overlooked.

Furthermore, more specific effects obtained in the first embodiment described above are as described in the following items (a) to (i).
(A) For example, when the earphone 20 is connected to the mobile phone 10 due to an erroneous operation and the user notices and disconnects immediately thereafter, that is, when recording is considered unnecessary, recording is unnecessary. As a result, the burden of recording processing can be reduced, and the recording capacity can be saved.

[Second Embodiment]
A. Constitution
(1) System Configuration FIG. 18 is a system configuration diagram for explaining main functions of the portable radio 11 according to the second embodiment of the present invention. The portable radio 11 has a broadcast receiving function for receiving a radio broadcast wirelessly transmitted from the radio station 41 via the transmission base station TS. The portable radio 11 has an interface for wired connection with the earphone 20 and has a function of outputting the sound output of the radio broadcast received by the broadcast receiving function to the earphone 20. When the earphone 20 is disconnected during broadcast reception, the portable radio 11 automatically starts recording the broadcast content being received, stops recording when the earphone 20 is connected, and instructs the user to play back. It has a function of reproducing the recorded broadcast contents according to the operation.

(2) Configuration of Portable Radio 11 Next, the configuration of the portable radio 11 will be described with reference to FIG. In FIG. 19, the CPU 200 controls the operation of each part of the portable radio 11 according to an event generated by an operation unit 205 described later and state data (described later) generated by an earphone connection unit 206 described later. A characteristic processing operation of the CPU 200 according to the gist of the present invention will be described in detail later.

  The ROM 201 includes a program area and a data area. Various programs executed by the CPU 200 are stored in the program area of the ROM 201. The various programs mentioned here include a main routine, an output process, an earphone operable process, an earphone inoperable process, and a reproducing process, which will be described in detail later. In the data area of the ROM 201, for example, reception channel data for channel selection is stored.

  The RAM 202 includes a work area (not shown) for temporarily storing various register / flag data, and a recording data storage unit 202a. In the recording data storage unit 202a, the compression-coded recording data output from the recording / reproducing unit 207 described later is stored under the control of the CPU 200. Note that the recording data here refers to audio data output by the radio broadcast receiving unit 203.

The radio broadcast receiving unit 203 outputs sound data obtained by receiving and demodulating a radio broadcast signal via the antenna ANT1 in accordance with a channel selection instruction given from the CPU 200. The display unit 204 includes a color liquid crystal panel and a display driver, and displays, for example, the name of a broadcasting station being received and recorded broadcast contents on the screen under the control of the CPU 200. The operation unit 205 includes a power switch for turning on / off power, a playback switch for instructing playback of recorded broadcast contents, a channel selection button for designating a reception channel, and the like, and generating an event corresponding to the operation of these switches and buttons. And output to the CPU 200.

  The earphone connection unit 206 includes means for detecting whether or not the earphone 20 (see FIG. 18) is connected. When the earphone connection unit 206 is connected to the earphone 20, it generates connection state data indicating that it is connected to the CPU 200. On the other hand, if not connected, connection state data representing non-connection is generated and output to the CPU 200. If the earphone connection unit 206 is connected to the earphone 20, it outputs the audio data supplied from the CPU 200 to the earphone 20.

  The recording / reproducing unit 207 records or reproduces audio data output from the radio broadcast receiving unit 203 under the control of the CPU 200. That is, when there is a recording instruction from the CPU 200, the recording / reproducing unit 207 compresses and encodes the audio data output from the radio broadcast receiving unit 203 and records it in the recording data storage unit 102 a of the RAM 102. On the other hand, when there is a reproduction instruction from the CPU 200, the reproduction data instructed for reproduction is read from the recording data storage unit 102 a of the RAM 102, and the reproduction data obtained by decompression decoding is output to the CPU 200.

B. Action
Next, the operation of the portable radio 11 having the above configuration will be described with reference to FIGS. When the user turns on the portable radio 11 by turning on the power switch of the operation unit 205, the CPU 200 executes the main routine shown in FIG. 20, advances the process to step SP1, and executes the output process. When the output process is executed, the CPU 200 proceeds to step SQ1 shown in FIG. 21, and instructs the radio broadcast receiving unit 203 to receive the broadcast of the reception channel designated by the user's channel selection operation. As a result, the radio broadcast receiving unit 203 outputs the audio data (broadcast content) received through the designated channel.

  Subsequently, in step SQ2, whether or not the earphone 20 is connected to the earphone connection unit 206 is determined based on the connection state data generated by the earphone connection unit 206. If the earphone 20 is connected to the earphone connection unit 206, the determination result is “YES”, the process proceeds to step SQ 3, and the audio data output from the radio broadcast reception unit 203 is supplied to the earphone connection unit 206. As a result, the earphone connection unit 206 outputs the audio data to the earphone 20 to the outside.

  On the other hand, if the earphone 20 is not connected to the earphone connecting unit 206, the determination result in step SQ2 is “NO”, and the process proceeds to step SQ4. In step SQ4, the recording / reproducing unit 207 is instructed to record the audio data (broadcast contents) output from the radio broadcast receiving unit 203, and in the subsequent step SQ5, the audio that is compressed and encoded by the recording / reproducing unit 207 in accordance with the recording instruction. Data is recorded in the recording data storage unit 202 a of the RAM 202. Then, the process proceeds to step SQ6, the audio data output from the radio broadcast receiving unit 203 is not supplied to the earphone connecting unit 206, the external output of the audio data is stopped, and the process is finished.

  When such output processing is completed, the CPU 200 executes step SP2 and subsequent steps of the main routine shown in FIG. In steps SP2 to SP6, it is determined whether or not there are events of “earphone non-connection → connection detection”, “earphone connection → non-connection detection”, “playback operation”, “power-off operation”, and “other operation”. If these events do not occur, the determination results in steps SP2 to SP6 are all “NO”, and the process returns to step SP2. On the other hand, when any of the above events occurs, a process corresponding to the generated event is executed. Hereinafter, the operation for each event will be described.

a. When earphone is not connected → detected
When the earphone connection unit 206 generates connection state data indicating that it is connected to the earphone 20, the CPU 200 detects an earphone non-connection → connection detection event. Then, the determination result in step SP2 is “YES”, and the process proceeds to step SP7 to execute the earphone operable process.

When the earphone operable process is executed, the CPU 200 proceeds to step SR1 shown in FIG. 22, and instructs the recording / reproducing unit 207 to stop recording. In step SR2, writing to the recording data storage unit 202a of the RAM 202 is prohibited and recording of audio data (broadcast contents) is stopped. Thereafter, the process proceeds to step SR3, where the audio data output from the radio broadcast receiving unit 203 is supplied to the earphone connecting unit 206, and the audio data is externally output to the earphone 20 connected to the earphone connecting unit 206, thus ending this processing. . When the earphone operable process is completed, the CPU 200 returns the process to step SP2 (see FIG. 20) of the main routine.

b. When earphone is connected → disconnected
When the earphone connection unit 206 generates connection state data indicating non-connection with the earphone 20, the CPU 200 detects an earphone connection → non-connection detection event. Then, the determination result in step SP3 shown in FIG. 20 is “YES”, the process proceeds to step SP8, and the earphone operation disabled process is executed.

When the earphone inoperability process is executed, the CPU 200 proceeds to step SS1 shown in FIG. In step SS1, the recording / reproducing unit 207 is instructed to record the audio data output from the radio broadcast receiving unit 203. Next, in step SS 2, the audio data compression-encoded by the recording / playback unit 207 is recorded in the recording data storage unit 202 a of the RAM 202 in accordance with the recording instruction in step SS 1. Then, the process proceeds to step SS3, the audio data output from the radio broadcast receiving unit 203 is not supplied to the earphone connecting unit 206, the external output of the audio data is stopped, and the process is finished. When the earphone inoperability process is completed, the CPU 200 returns the process to step SP2 (see FIG. 20) of the main routine.

c. When a playback operation is performed
When a playback switch provided in the operation unit 205 is operated, the CPU 200 detects a playback switch event. Then, the determination result in step SP4 shown in FIG. 20 is “YES”, the process proceeds to step SP9, and the reproduction process is executed. When the reproduction process is executed, the CPU 200 proceeds to step ST1 shown in FIG. 24 and displays a list of broadcast content items recorded in the recording data storage unit 202a of the RAM 202 on the display unit 204. Note that the broadcast content item referred to here indicates recording header information including, for example, a recording start date and a reception channel.

Next, in step ST2, a broadcast content item to be played back is selected from the broadcast content items displayed in a list on the display unit 204 in accordance with a user operation. In step ST3, the recording / reproducing unit 207 is instructed to reproduce the broadcast content of the item selected in step ST2. As a result, the recording / reproducing unit 207 reads out the recorded data of the broadcast content instructed to be reproduced from the recorded data storage unit 202 a of the RAM 202 and outputs the reproduced data (audio data) obtained by decompression decoding to the CPU 100. In step ST4, reproduction data (audio data) output from the recording / reproduction unit 207 is supplied to the earphone connection unit 206, and the audio data is externally output to the earphone 20 connected to the earphone connection unit 206. Finish. When such reproduction processing is completed, the CPU 200 returns the processing to step SP2 (see FIG. 20) of the main routine.

d. When the power is turned off
When the power-off operation is performed, the determination result in step SP5 shown in FIG. 20 is “YES”, the process proceeds to step SP10, and after executing the power-off process, this process is completed.

e. When other operations are performed
When other operations other than those described above are performed, the determination result in step SP6 shown in FIG. 20 is “YES”, the process proceeds to step SP11, and other processes are executed. Other processing refers to processing such as volume level adjustment and reception channel switching. Then, after the other processes are executed, the process returns to step SP2.

  As described above, in the second embodiment, when the earphone 20 is disconnected from the earphone connection unit 206 during the broadcast reception and the earphone 20 is not connected, the broadcast content being received is automatically recorded and the earphone connection is started. When the earphone 20 is connected to the unit 206, the recording is stopped, and the recorded broadcast content is reproduced according to the reproduction instruction operation of the user. That is, since the broadcast content missed during listening can be confirmed later, it is possible to prevent the broadcast content from being missed.

  Furthermore, in the second embodiment, when the earphone 20 is disconnected and the earphone operation is disabled, the external output of the audio data is stopped. Therefore, it is possible to reduce the burden of transmission processing by not performing unnecessary transmission. . In addition, when the earphone 20 is connected after the earphone operation is disabled and the operation returns to the earphone operation enabled, recording started when the earphone operation is disabled is stopped. You can also
