Description

  The present invention relates to a portable terminal device and a program in which an external output device that outputs video can be connected to a device main body.

Conventionally, as a mobile phone device with a digital TV broadcast receiving tuner, for example, while watching a TV broadcast, a recording operation for recording the broadcast content currently being watched is started when a call is received, and the recording is continued at the end of the call. On the other hand, a technique is known in which recorded contents are sequentially reproduced and output (chased reproduction) from the beginning (see Patent Document 1).
Japanese Patent Laid-Open No. 2002-247490

 However, in the technique of Patent Document 1 described above, when the call time (interruption period) is long, the current reception content is quite easy if the playback speed during chasing playback (time shift playback) is about 1.2 times faster. As a result, after the incoming call, everything is viewed as a chasing playback. For example, although it is a live sports program, even a decisive moment scene (for example, a goal scene) can only be viewed as a chasing playback. There wasn't.

Thus, conventionally, it is difficult to view a television program currently being broadcast in real time during time-shift playback.
By the way, when watching TV with multiple people, for example, when a person who has left the place temporarily returns, he wants time-shift playback from the interrupted point, but other people can watch real-time watching as it is. I hope. In addition, even when watching TV alone, as a way to enjoy it, there may be a case where real-time viewing is desired simultaneously with time-shift playback.

 This is not limited to parallel display of time-shifted playback video and real-time video, and even when video content is read out and played back from external media, for example, a person who has left the spot temporarily When it comes back, it wants to reproduce from the interrupted point, but other people want the reproduction as it is, and the same problem as described above occurs.

  An object of the present invention is to enable simultaneous output of a first video and a second video by a display unit on the device main body side and an external output device connected to the device main body.

The invention according to claim 1 (first invention) is a portable terminal device having a reception output function for receiving and outputting a television broadcast, and a recording / reproducing function for sequentially recording the broadcast contents and reproducing the recorded contents. When it is determined that the external output device that outputs the video is connected to the apparatus main body and the external output device is connected by the determination means when receiving the television broadcast. In addition to sequentially outputting the video obtained by one of the reception output function and the recording / playback function from the external output device as the first video, the video obtained by the other function is output by the first function. Output control means for sequentially outputting from the display unit on the apparatus main body side as a second video different from the video.
Furthermore, a program for realizing the main functions shown in the invention described in claim 1 is provided to the computer (the invention described in claim 9).

The invention described in claim 1 described above may be as follows.
The output control means sequentially outputs broadcast reception contents obtained by the reception output function from the external output device if an external output device is connected, and if the external output device is not connected, the apparatus main body side Are sequentially output from the display section (the invention according to claim 2).

 The recording / playback function starts a recording operation for sequentially recording subsequent video in response to the interruption instruction during video output from the external output device, and then records the recorded content in response to the interruption return instruction. In response to the start of the reproduction operation in a state where the reproduction operation for sequentially reproducing is started, and the output control unit sequentially outputs the video obtained by the reception output function as the first video from the external output device. The playback contents are sequentially output from the external output device or the display unit on the apparatus main body.

 The recording / reproducing function starts a reproducing operation of sequentially reproducing the recorded contents in response to a review instruction in a state where the video output from the external output device is sequentially recorded, and the output control means In a state in which the video obtained by the reception output function is sequentially output from the external output device as the first video, the output control means sends the playback content to the external output device or the output according to the start of the playback operation. The information is sequentially output from the display unit on the apparatus main body side.

  When the video obtained by the reception output function is sequentially output as a real-time video from an external output device, the recording is performed when time-shift playback is instructed to retroactively play back the recorded content in which the real-time video is recorded. The time-shifted video obtained by the reproduction function is sequentially output from the display unit on the apparatus main body side (the invention according to claim 5).

  The recording / playback function sequentially overwrites and records the broadcast content for the capacity in a recording memory for receiving and temporarily recording the current broadcast content, and in the state where the recorded content is time-shifted playback, When it is detected that the playback position has caught up with the recording position by comparing the playback position with the playback position, the playback operation is terminated (the invention according to claim 6).

  The output control means switches the output destination of the first and second images between the external output device and the display unit on the apparatus main body in response to an output switching instruction (the invention according to claim 8).

The invention according to claim 7 (second invention) is a portable terminal device having a playback function of reading and sequentially playing back video content recorded on an external recording medium that can be detachably attached to the device body. A determination means for determining whether an external output device for outputting video is connected to the apparatus main body during reproduction of the video content; and when the determination means determines that the external output device is connected, The video sequentially read from the first reproduction start position is sequentially output from the external output device as the first video, and the second video different from the first video is sequentially read from the second reproduction start position. And an output control means for sequentially outputting from the display unit on the apparatus main body side.
Further, a program for realizing the main functions shown in the above-described invention according to claim 7 is provided to the computer (the invention according to claim 10).

According to the second aspect of the present invention, when an external output device is connected to the apparatus main body, it is possible to simultaneously output videos from different playback start positions depending on the display on the apparatus main body side and the external output device.

(Example 1)
Hereinafter, a first embodiment of the present invention will be described with reference to FIGS.
This embodiment exemplifies a case where the present invention is applied to a mobile phone device as a mobile terminal device. FIG. 1 shows that a mobile phone device 1 with a digital TV broadcast receiving function is placed (connected) on a cradle (charging base) 2. It is the figure which showed the state which carried out.
This mobile phone device 1 is a foldable one having two housings that can be opened and closed. In addition to a telephone function (call function), a mail function, an Internet connection function (Web access function), a TV broadcast receiving function, TV broadcast recording and playback functions are provided.

  In the state where the mobile phone device 1 is placed (connected) on the cradle 2, the PC (personal computer) with the TV broadcast receiving function receives the TV broadcast signal received by the TV broadcast receiving function via the cradle 2. Alternatively, external output is performed by transmitting to an external output device 3 such as a fixed television apparatus by infrared communication. In this case, not only the external output of the television broadcast but also, for example, movie content supplied externally from a recording medium or downloaded and received from the Internet can be transmitted to the external output device 3 via the cradle 2 and viewed. .

  The cradle 2 has a charging function for supplying a charging current to a secondary battery (not shown) of the mobile phone device 1 when the mobile phone device 1 is placed while being connected to an AC power source. An intelligent cradle having a video transfer function for transferring a video signal to the external output device 3 by relaying the video signal from the mobile phone device 1 to the external output device 3 via infrared communication. is there. The external output device 3 receives and outputs a TV video signal and a TV audio signal transmitted from the mobile phone device 1 via the cradle 2. At this time, the portable output size transmitted from the cradle 2 by infrared communication is used. When this video signal is received, the video signal is changed to its current screen size and displayed and output.

FIG. 2 is a block diagram showing basic components of the cellular phone device 1 with a digital television broadcast receiving function.
The CPU 11 is a central central processing unit that controls the overall operation of the mobile phone device according to various programs in the storage unit 12. The storage unit 12 is an internal memory, and has a program area and a data area. In this program area, a program for realizing the present embodiment in accordance with an operation procedure shown in FIGS. Stored. The external recording medium 13 is a removable portable memory that supplies various data programs externally. For example, the external recording medium 13 is composed of smart media, an IC card, and the like, and supplies contents such as videos and music to the outside. Even in this case, the external recording medium 13 is used. The memory 14 is an internal memory having a work area, and various data in the memory 14 is saved in the storage unit 12 as necessary.

  The telephone communication unit 15 takes in a signal from the reception side of a transmission / reception unit (baseband unit) connected to an antenna that constitutes a radio unit, demodulates it into a reception baseband signal, and then receives a reception speaker via the acoustic control unit 16. The sound is output from 17. Further, the telephone communication unit 15 takes in the voice data input from the transmission microphone 18 from the acoustic control unit 16, encodes it into a transmission baseband signal, and then gives it to the transmission side of the transmission / reception unit to output from the antenna. . On the other hand, the video content received and acquired through the telephone communication unit 15 by the Internet connection function or the like is given to the main display unit 20 such as an LCD (Liquid Crystal Display) via the display control unit 19 and is displayed and output. The sub display unit 21 displays the current date and time, a simple message, an icon, and the like.

  The TV broadcast receiving unit 22 receives terrestrial digital TV broadcasts for mobile receivers such as mobile phones, and can receive electronic program guides (EPG) in addition to TV video and audio information. The TV broadcast receiving unit 22 is connected to the TV antenna and receives a broadcast unit (analog circuit unit) that extracts a broadcast signal. The received broadcast signal is demodulated by OFDM (orthogonal frequency division multiplexing) or multiplexed. It has a digital circuit section that separates video, audio, and data (character data) from a signal, decodes them, and decompresses compressed data. Here, the CPU 11 causes TV video data and character data to be displayed and output from the main display unit 20, and causes TV sound data to be output from the sound speaker 23.

  The key operation unit 24 performs dial input, character input, command input, and the like, and the CPU 11 executes processing according to a key input signal from the key operation unit 24. The cradle connection unit 25 charges a secondary battery (not shown) with a charging current from the cradle 2 when connected to the cradle 2, and the CPU 11 detects a connection detection signal output from the cradle connection unit 25. Based on the above, it is detected whether the apparatus main body is connected to the cradle 2 or not.

  In this case, the CPU 11 determines whether or not the external output device 3 is connected based on whether or not it is connected to the cradle 2 during the operation of the television broadcast receiver 22, and is not connected to the cradle 2. When the external output device 3 is not connected, the broadcast reception contents are sequentially output from the main display unit (portable screen) 20, but when it is connected to the cradle 2 (the external output device 3 is connected). The broadcast reception content is transmitted to the external output device 3 via the cradle 2 to be externally output.

  When the incoming call is detected during the reception and output of the television broadcast, the CPU 11 starts the recording operation of the television broadcast and then continues the recording operation until the end of the call is detected. In this case, the CPU 11 generates a recording file and records and saves it in the storage unit 12 or the recording medium 13. Then, when the reproduction of the recording file is instructed by the user operation during the reception of the television broadcast, the CPU 11 executes the reproduction operation. Whether the recording file is read and the video is reproduced and output from the main display unit 20. Then, it is determined whether to reproduce and output from the external output device 3.

Next, the operation concept of the mobile phone device in the first embodiment will be described with reference to the flowcharts shown in FIGS. Here, each function described in these flowcharts is stored in the form of a readable program code, and operations according to the program code are sequentially executed. In addition, the operation according to the above-described program code transmitted via the transmission medium can be sequentially executed. This is the same in other embodiments described later. In addition to the recording medium, the program / data supplied from the outside via the transmission medium can be used to execute operations specific to this embodiment.
3 and 4 are flowcharts showing an outline of the operation of the characteristic part of the present embodiment in the overall operation of the mobile phone device. When the flow of FIG. 3 and FIG. Returning to the operation flow (not shown).

3 and 4 are flowcharts showing TV application processing that is started in response to an instruction operation for starting a TV.
First, the CPU 11 activates the television broadcast receiving unit 22 in response to an instruction operation for starting the television and starts reception of the television broadcast (step A1), and then accesses the cradle connection unit 25 so that the apparatus main body enters the cradle 2. It is checked whether or not it is connected to the external output device 3 via the cradle 2 based on whether or not it is placed (connected) (step A2). As a result, if it is not connected to the external output device 3 (NO in Step A2), the broadcast reception content (real-time video) from the television broadcast receiving unit 22 is output from the main display unit (portable screen) 20 (Step A6). ).

 On the other hand, if the external output device 3 is connected via the cradle 2 (YES in step A2), YES / NO whether the broadcast reception content (real-time video) is transmitted to the external output device 3 for external output. A confirmation message for inquiring in a form is displayed as a guide (step A3). When an affirmative response “Yes” is received from the user who has confirmed this guidance display, external output of the real-time video is started by transmitting the broadcast reception content to the external output device 3 (step A4), but a negative response “No” is received. Is received, the process proceeds to step A6 described above, and a real-time video is output from the main display unit 20.

 In this state where the real-time video is being output from the main display unit 20 or the external output device 3, the CPU 11 checks whether there is any operation (step A7), or checks whether there is an incoming call (step A8). Furthermore, a change in the connection state of the external output device 3 is checked according to whether or not the cradle 2 is connected (step A9). Now, when an incoming call is detected (YES in step A8), the incoming call is notified. At that time, if the line connection is established by an off-hook operation (YES in step A10), the external output device 3 is connected. (YES in step A11), whether broadcast reception contents are being output externally, that is, the output destination of the real-time video is not the external output device 3 (main display unit 20) (NO in step A12) ), The real-time video is transmitted to the external output device 3, and the external output is started (step A13).

  Then, after starting the recording operation for sequentially recording the broadcast reception contents (step A14), the CPU 11 performs a call process (step A15) until the line is disconnected by an on-hook operation or the like (step A16). However, when the line is interrupted (YES in step A16), the recording operation is terminated in response thereto (step A17). As a result, the current recording file recorded in the storage unit 12 or the recording medium 13 has the broadcast content in which the television viewing is interrupted by the current call.

  Then, after selecting the recorded file as a reproduction target (step A18), the CPU 11 proceeds to the flow of FIG. 4 and starts a reproduction operation of the recorded file (recorded content) (step A22). In this way, after starting the recording operation of sequentially recording the subsequent video when receiving a telephone call (at the time of interruption instruction) while watching TV, the CPU 11 sequentially reproduces the recorded contents at the end of the call (at the time of interruption return instruction). Start playback operation. In this case, time-shift playback is started in which the content of the recorded file is played back to the beginning position. The time shift reproduction is performed, for example, at 1.2 times speed.

 Then, the CPU 11 checks whether or not the external output device 3 is connected based on whether or not the cradle 2 is connected (step A23). If the external output device 3 is not connected, the reproduction content (time shift) is displayed on the main display unit 20. Video) is output (step A26). As a result, the video displayed on the main display unit 20 is switched from the real-time video to the time-shifted video. If the external output device 3 is connected (YES in step A23), it is determined whether a real-time video is being output from the external output device 3 (step A24). Is output from the main display unit 20 (step A26), but if the real-time video is not output externally (NO in step A24), the time-shifted video is transmitted to the external output device 3 for external output (step A25). ). Thereafter, returning to the flow of FIG. 3, the presence / absence of an operation (step A7), the presence / absence of an incoming call (step A8), and the presence / absence of a change in external connection are checked (step A9).

 Here, when the connection state of the external output device 3 changes, that is, when the external output device 3 is connected or when the connection state of the external output device 3 is released (YES in step A9), Returning to step A2, real-time video is output from the external output device 3 or the main display unit 20 (steps A2 to A6). That is, when the apparatus main body is removed from the cradle 2 and the connection of the external output device 3 is released in a state where the real-time video is displayed and output on the external output device 3, the real-time video is transmitted from the external output device 3 to the main display unit. 20 is switched and displayed. On the contrary, when the external output device 3 is connected in a state where the real-time video is displayed and output on the main display unit 20, the real-time video is received from the main display unit 20 after receiving confirmation from the user. 3 is displayed.

 If any operation is performed (YES in step A7), the flow proceeds to the flow of FIG. 7 to determine whether the operation is a reproduction instruction operation for instructing reproduction of recorded content (step A19), or switching of the video output destination is instructed. Whether it is a switching operation to be performed (step A27) or an ending operation for instructing the end of reproduction (step A29). Now, when a reproduction end instruction operation is performed (YES in step A29), the reproduction operation is ended (step A30), and then the process returns to step A7 in FIG.

 When a video output destination switching instruction operation is performed (YES in step A27), the display content is switched between the main display unit 20 and the external output device 3 (step A28). For example, when a real-time video is displayed on the external output device 3 and playback content (time-shifted video) is displayed on the main display unit 20, when switching of the video output destination is instructed, the main display unit 20 is displayed. A real-time video is displayed, and a time-shifted video is displayed on the external output device 3.

 When the recorded content playback instruction operation is performed (YES in step A19), the recorded content menu is displayed and output (step A20). This menu screen is a list of file names that are read out from various recorded contents that have been stored due to recording reservations, etc. When any recorded content is selected and designated for playback from this list of file names (Step A21) After starting the reproduction operation of the selected content (Step A22), the CPU 11 proceeds to the same processing as described above (Steps A23 to A26). If a TV viewing end instruction operation is performed (YES in step A31), the process exits from this flow, but if any other operation is performed (NO in step A31), this operation corresponds to this operation. As processing, for example, volume adjustment processing, luminance adjustment processing, and the like are performed (step A32).

 As described above, in the first embodiment, the CPU 11 determines whether or not the external output device 3 is connected to the apparatus main body when receiving the television broadcast. If the external output device 3 is connected, the television reception is performed. In addition to sequentially displaying the video obtained by one of the output function and the recording / playback function from the external output device 3, the video obtained by the other function is sequentially displayed from the main display unit 20 on the apparatus body side. By displaying, it is possible to simultaneously display and output the real-time video currently being broadcast and the time-shifted video. Therefore, for example, when a real-time video is externally output from the external output device 3, when a person who has temporarily left the place returns, when playback from that interrupted location is desired, the time Shift video can be output from the main display unit 20.

 In this case, the CPU 11 sequentially displays real-time video from the external output device 3 if the external output device 3 is connected, and sequentially displays it from the main display unit 20 if the external output device 3 is not connected. Thus, the real-time video can be externally displayed from the external output device 3 simply by placing (connecting) the apparatus main body to the cradle 2. In addition, in response to the output switching instruction, the output destination of the real-time video and the time-shifted video can be easily switched between the external output device 3 and the main display unit 20.

 If the mobile screen is divided into two parts and displayed in parallel in order to simultaneously display the time-shifted playback video and the real-time video on the main display unit 20, each video becomes extremely small, making it difficult to see and powerful. In addition, it is difficult for a plurality of people to simultaneously watch TV on the main display unit 20, but simultaneously using the external output device 3 and the main display unit 20 as in the first embodiment. If displayed, these problems will not occur.

In addition, the CPU 11 starts a video recording operation for sequentially recording subsequent TV images in response to an off-hook operation at the time of incoming call during reception of a TV broadcast, and then starts time-shifted playback in response to the on-hook operation. Then, by causing the external output device 3 or the main display unit 20 to perform display output, even if the television viewing is interrupted by a call, the suspended broadcast content can be viewed at the end of the call. In this case, simultaneous display of the real-time video currently being broadcast and the time-shifted video is possible.
(Example 2)

A second embodiment of the present invention will be described below with reference to FIGS.
In the first embodiment described above, broadcast reception contents are sequentially recorded. However, in this second embodiment, a link buffer having a recording capacity for a predetermined time (for example, one minute) is provided. Broadcast reception contents are sequentially overwritten and recorded in the link buffer.
Here, the same or the same names in both embodiments are denoted by the same reference numerals, the description thereof will be omitted, and the following description will focus on the features of the second embodiment. .

FIG. 5 is a diagram for explaining the link buffer 30.
The link buffer 30 is a buffer having a recording capacity for one minute, and the CPU 11 sequentially overwrites and records the broadcast contents corresponding to the capacity, and at the same time plays back the recorded contents in a time-shifted manner. By comparing the position P1 and the reproduction position P2, it is detected whether the reproduction position P2 has caught up with the recording position P1, and when the reproduction position P2 has caught up, the reproduction operation is automatically terminated.

 Here, (A) shows a case where time-shifted playback is instructed before one minute has elapsed since the start of recording, and (B) shows that the recording position P1 is sequentially updated in accordance with the recording operation. (C) is a diagram showing a case where the recording position P1 is overwritten after the recording position P1 is returned from the end position of the link buffer 30 to the start position. As in the first embodiment described above, the time shift reproduction is performed at, for example, 1.2 times speed.

FIG. 6 is a flowchart showing TV application processing that is started in response to an instruction operation for starting the TV in the second embodiment.
First, the CPU 11 activates the television broadcast receiving unit 22 in response to an instruction operation for starting the television to start reception of the television broadcast (step B1), and starts a recording operation for recording the received content in the link buffer 30. (Step B2). In this case, after clearing the contents of the link buffer 30 and aligning the recording position P1 with the head position, the recording operation for recording the broadcast reception contents is started.

 In this state, it is checked whether it is connected to the external output device 3 via the cradle 2 (step B3). If it is not connected to the external output device 3, broadcast reception content (real-time video) from the TV broadcast receiving unit 22 is checked. Is output from the main display unit 20 (step B4), but if the external output device 3 is connected (YES in step B3), the real-time video is transmitted to the external output device 3 for external output (step B5). .

 In a state where the real-time video is output from the main display unit 20 or the external output device 3 in this way, the CPU 11 checks whether or not there is any operation (step B6), or depending on whether the cradle 2 is connected or not. A change in the connection state is checked (step B7). Now, when the connection state of the external output device 3 changes, that is, when the external output device 3 is connected or when the connection of the external output device 3 is released (YES in Step B), the above-described Step B3 Then, the broadcast reception content (real-time video) is output from the external output device 3 or the main display unit 20 (steps B3 to B5).

 If any operation has been performed (YES in step B6), it is checked whether an instruction operation for instructing the review of the previous broadcast content has been performed (step B8). As the corresponding processing, for example, volume adjustment processing, luminance adjustment processing, and the like are performed (step B9). If the operation is a review instruction operation (YES in step B8), the playback operation is performed with the top position of the link buffer 30 as the playback position P2. Is started (step B10). Then, it is checked whether it is connected to the external output device 3 (step B11). If it is not connected to the external output device 3, the recorded contents of the link buffer 30 (instead of the real-time video displayed on the main display unit 20) (Time-shift video) is output (step B12).

 If the external output device 3 is connected (YES in step B11), the output of the time shift video is started instead of the real time video displayed on the external output device 3 (step B13), and the main display unit The real-time video output is started from 20 (step B14). Then, it is checked whether or not a reproduction end instruction operation has been performed (step B15). When an end instruction is received, the reproduction operation is terminated at that point (step B18), and the process proceeds to step B6 described above. If the end instruction operation is not performed (NO in step B15), the current recording position P1 is compared with the reproduction position P2 (step B16), and it is determined whether the reproduction position P2 has caught up with the recording position P1 (step B16). B17) When catching up, the reproduction operation is automatically terminated (step B18).

As described above, in the second embodiment, in the state where the external output device 3 is watching the television broadcast while the CPU 11 is sequentially overwriting and recording the broadcast content for the capacity in the link buffer 30, the previous broadcast content is stored. When the review is instructed, the recorded content of the link buffer 30 is reproduced and displayed on the main display unit 20 while continuing the recording operation to the link buffer 30, so that the immediately preceding video is displayed on the mobile screen while watching the television broadcast. It can be easily confirmed.
In this case, when time-shifted reproduction is performed together with the recording operation, when the reproduction position P2 catches up with the recording position P1 by comparing the current recording position P1 and the reproduction position P2, the reproduction operation is automatically ended. be able to.
(Example 3)

In the third embodiment, the movie supplied from the outside is shown. When content or the like is reproduced and output, the reproduction video from the first reproduction position and the reproduction video from the second reproduction position that are arbitrarily designated can be output from the external output device 3 and the main display unit 20. . That is, the same content is reproduced with a time difference from the first and second reproduction positions.
Here, in the first and third embodiments, the same or the same names in the first embodiment are denoted by the same reference numerals, the description thereof will be omitted, and the following description will be focused on the characteristic portions of the third embodiment. It shall be.

FIG. 7 is a flowchart showing a playback process started in response to a content playback instruction operation in the third embodiment.
First, the CPU 11 accesses the external recording medium 13 and displays and outputs a content menu for guiding a list of contents recorded on the external recording medium 13 (step C1). Here, when an arbitrary content is selected as a reproduction target from the menu screen (step C2) and the arbitrary position is designated by the user as the first reproduction position (step C3), the CPU 11 The reproduction operation is started from this first reproduction position (step C4).

 Then, it is checked whether it is connected to the external output device 3 via the cradle 2 (step C5). If it is connected to the external output device 3, the process proceeds to step C11 described later, but is connected to the external output device 3. If not (NO in step C5), the reproduced video is output from the main display unit 20 (step C6). Here, it is checked whether any operation has been performed (step C7), or a change in the connection state of the external output device 3 is checked (step C10). If an end operation for instructing the end of playback is performed (YES in step C8), the playback process ends at this point (step C9), but if the connection state of the external output device 3 changes, That is, when connected to the external output device 3 (YES in step C10), the playback video is switched from the main display unit 20 to the external output device 3 (step C11).

 In this state, the presence / absence of operation is checked (step C12), and the presence / absence of connection change of the external output device 3 is checked (step C13). Here, when a terminal reproduction instruction operation for instructing to display the reproduction content on the mobile screen is performed (YES in step C14), a confirmation message for inquiring whether to perform time difference reproduction is displayed as a guide (step C15). . Here, when the time difference reproduction is designated by the user and an arbitrary position is designated by the user as the second reproduction position (step C16), the CPU 11 performs the reproduction operation from the first reproduction position described above in parallel. The playback operation from the second playback position is started, and the playback video from the second playback position is output from the main display unit 20 (step C17).

FIG. 8 is a diagram for explaining two reproduction positions arbitrarily designated for the content file 31 selected as a reproduction target.
When the content playback is started in the state where the first playback position AP and the second playback position BP are arbitrarily designated in the content file, the playback operation from the first playback position AP is started and The reproduced video is output to the external output device 3. When the terminal playback is instructed and the second playback position BP is designated, the playback operation from the second playback position BP is started and the playback video is output from the main display unit 20. As a result, the reproduction operation from the first reproduction position AP and the reproduction operation from the second reproduction position BP are executed in parallel. Note that the content externally supplied from the external recording medium 13 may be downloaded and received via the Internet and stored in the external recording medium 13.

 In this state, when an instruction operation for switching the output destination of the reproduced video is performed (YES in step C18), the display contents are displayed between the main display unit 20 and the external output device 3 as in the first embodiment described above. Are switched (step C19). For example, in the state where the playback video from the first playback position AP is displayed on the external output device 3 and the playback video from the second playback position BP is displayed on the main display unit 20, the video output destination is switched. When instructed, the main display unit 20 displays the playback video from the first playback position AP, and the external output device 3 displays the playback video from the second playback position BP. When a reproduction end instruction operation is performed (YES in step C20), the process proceeds to step C9 described above to end the reproduction operation.

 As described above, in the third embodiment, when the content externally supplied from the external recording medium 13 is reproduced and output, the reproduced video from the arbitrarily designated first reproduction position AP and the second reproduction position are displayed. By simultaneously outputting the playback video from the BP from the external output device 3 and the main display unit 20, it is possible to view different contents (contents having a time difference) at the same time even for the same contents. In this case, when the playback operation from the first playback position AP and the playback operation from the second playback position BP are performed in parallel, if a fast forward operation or a fast reverse operation is performed, both of them are performed. Fast forward and fast reverse may be performed simultaneously.

 In each of the above-described embodiments, whether or not the apparatus main body is placed (connected) on the cradle 2 is checked to determine whether or not it is connected to the external output device 3 via the cradle 2. The cradle 2 may be provided with a connector portion, and whether or not the external output device 3 is connected may be determined based on whether or not the external output device 3 is connected to the connector portion. Further, the external output device 3 may be directly connected to the apparatus main body by a cable or a connector. Further, in each of the above-described embodiments, the case where infrared communication is performed as the communication unit between the cradle 2 and the external output device has been illustrated, but for example, short-range wireless communication may be used.

In each of the above-described embodiments, a PC or a fixed television device is exemplified as the external output device, but a projection screen or the like may be used. Further, the television broadcast receiving unit 22 may be one equipped with a double tuner.
In each of the above-described embodiments, the audio output is not particularly mentioned. However, when the video is simultaneously output from the external output device and the mobile phone device, the audio is individually output. In this case, a sound output from the earphone may be a condition on the mobile phone device side.
In addition, the present invention is not limited to a mobile phone device with a TV broadcast reception function, and can be applied to a mobile terminal device such as a PDA, an electronic camera, an electronic watch, and a music player with a TV broadcast reception function.
