Description

  The present invention relates to a television receiver and a program having a function of receiving and outputting a television broadcast radio wave and a function of sequentially recording and reproducing and outputting the received broadcast content, and in particular, recording the received content while continuing to record it. The present invention relates to a television receiver and a program having a function of reproducing and outputting contents in parallel (chase reproduction function).

Conventionally, a television receiver that receives and outputs a television broadcast has a recording function for receiving and recording the television broadcast. When a telephone call is received while watching the television, the broadcast content is recorded. There is known a television receiver that has a function of sequentially reproducing and outputting recorded contents from the start position while continuing the recording operation after the call ends, that is, a so-called chasing playback function (see Patent Document 1).
JP 2002-247490 A

  By the way, this type of chasing playback function operates separately from the “reception output mode (normal mode)” for receiving and outputting the content of the program currently being broadcast or the “reproduction output mode” for reproducing and outputting the recorded content. In this “reproduction output mode”, chasing reproduction is performed. Here, when the playback position catches up with the recording position during chasing playback, since there is no recording content after that, it is common to automatically stop the playback operation at this point, If the recording is continued in a state where the reproduction is stopped, it is possible to continue the reproduction from the content recorded within the stop period.

However, even if the playback operation is temporarily stopped even for a short time, the television broadcast cannot be viewed continuously.
Therefore, if the viewer confirms the playback stop when the playback position catches up with the recording position during the chasing playback, and then performs an operation to switch from the “playback output mode” to the “reception output mode”, Thereafter, it becomes possible to view the contents of the program currently being broadcast in real time. However, in the case where continuous viewing without interruption is desired, it is necessary to perform a mode switching operation without putting a gap. In addition, performing the mode switching operation every time the playback position catches up with the recording position leaves attention to the broadcast contents even temporarily, which may hinder concentrated viewing.

  The problem of the present invention is that even when the playback position catches up with the recording position during the chasing playback, it is possible to smoothly shift from the chasing playback to the state of receiving and outputting the contents of the current broadcast without performing any special operation. Is to do so.

The invention according to claim 1 is a television receiver having a function of receiving and outputting a television broadcast radio wave and a function of sequentially recording and reproducing and outputting the received broadcast content, and sequentially outputs the received broadcast content. A first mode switching means for arbitrarily switching between the reception output mode and the reproduction output mode for reproducing the recorded content according to a user operation, and when the reproduction of the recorded content is instructed during the recording operation of the received broadcast content The chasing playback means for reproducing and outputting the recorded contents in parallel in the playback output mode while continuing the recording operation, and comparing the current recording position and the playback position during the playback operation by the chasing playback Discriminating means for discriminating whether or not the playback position has caught up with the recording position, and when the discriminating means discriminates that the playback position has caught up with the recording position, the playback output mode is determined. And a second mode switching means for switching to a state in which the current broadcast content is received and output by releasing the mode and returning to the reception output mode.
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 may be as follows.
When it is determined by the determination means that the current playback position has caught up with the recording position, message information for guiding the return to the reception output mode is output (the invention according to claim 2).

In response to an output interruption instruction in a state in which the received content is being sequentially output in the reception output mode, an operation for sequentially recording the received content thereafter is started, and then a response to the playback instruction of this recorded content is made. When the playback operation is started, the second mode switching means cancels the playback output mode and returns to the reception output mode when the current playback position catches up with the recording position. Described invention).
The output interruption instruction is not limited to an arbitrary instruction by a user operation. For example, in a mobile phone device, an output interruption may be automatically instructed when a call is received (the same applies hereinafter).

  In response to an output interruption instruction in a state in which the received content is being sequentially output in the reception output mode, an operation for sequentially recording the received content thereafter is started, and then a response to the playback instruction of this recorded content is made. When the reproduction operation is started, the first mode switching means cancels the reproduction output mode and returns to the reception output mode when a predetermined operation is performed (the invention according to claim 4). ).

  When the playback output mode is canceled and the reception output mode is restored during the chasing playback operation, the playback operation is stopped and the recording operation is ended at that time.

  In response to the output interruption interrupt instruction in the state where the reception contents are being output sequentially in the reception output mode, the operation of sequentially recording the subsequent reception contents is started, and then the interrupt release instruction is responded. When the guidance information prompting that the recorded content should be reproduced is output and a reproduction instruction is received accordingly, the reproduction is started from the head position of the recorded content (invention of claim 6).

Here, when the interrupt is canceled, guidance information indicating that the mode is returned to the reception output mode is output, and when a return instruction is received in response thereto, the first mode switching means switches to the reception output mode. You may make it return. (Invention of Claim 7).
In addition, after returning to the reception output mode, guidance information indicating that the broadcast content temporarily recorded during the interruption period is in an unviewed state is output, and in response thereto, a reproduction instruction for the temporary recording is output. The first mode switching means may be configured to reproduce and output the temporarily recorded content by switching to the reproduction output mode.

  According to the first aspect of the present invention, when the reproduction of the recorded content is instructed during the recording operation of the received broadcast content, the recorded content is concurrently processed in the reproduction output mode while continuing the recording operation. Starts chasing playback to output and compares the current recording position with the playback position during this chasing playback operation to determine whether the playback position has caught up with the recording position. Since the playback output mode is canceled and the current broadcast content is switched to the reception output mode by returning to the reception output mode, even if the playback position catches up with the recording position during chasing playback, a special It is possible to make a smooth (seamless) transition from chasing playback to receiving output during the current broadcast without any operation. Even switched in the reception output, it is possible to watch concentrating broadcast content to its end.

  According to the second aspect of the invention, in addition to the same effect as the first aspect of the invention described above, the message information for guiding the return to the reception output mode when the reproduction position catches up with the recording position is provided. Since the data is output, it is possible to return to the reception output mode after allowing the user to confirm the automatic switching of the mode. Note that message information may be displayed in a pop-up at one corner of the television screen (playback screen).

  According to the invention described in claim 3, in addition to having the same effect as that of the invention described in claim 1 described above, in response to an output interruption instruction in a state where reception contents are sequentially output in the reception output mode. After starting the operation to sequentially record the received content after that, when the playback operation is started in response to the playback instruction of this recording content, the playback is performed when the current playback position catches up with the recording position. Since the output mode is canceled and the reception output mode is restored, in chasing playback after output interruption, it is natural to return to the reception output mode when the playback position catches up with the current recording position. It becomes possible to cope with various movements.

  According to the invention described in claim 4, in addition to having the same effect as that of the invention described in claim 1 described above, in response to an output interruption instruction in a state where reception contents are sequentially output in the reception output mode. After starting the operation to sequentially record the received content after that, when the playback operation is started in response to the playback instruction of this recorded content, the playback output mode is set when a predetermined operation is performed. Since it is canceled and returned to the reception output mode, it is possible to return to the reception output mode as necessary before the playback position catches up with the recording position, and the convenience can be increased.

  According to the invention described in claim 5, in addition to having the same effect as that of the invention described in claim 1 described above, when canceling the playback output mode and returning to the reception output mode during the chasing playback operation, Since the playback operation is stopped and the recording operation is terminated at that time, meaningless recording can be prevented and wasteful power consumption can be suppressed.

  According to the invention described in claim 6, in addition to having the same effect as that of the invention described in claim 1 described above, in response to an interrupt instruction for interrupting output in a state in which received contents are sequentially output in the reception output mode. In response to this interrupt release instruction, guidance information prompting that the recorded contents should be played is output, and a playback instruction is received accordingly. In this case, since the playback is started from the head position of the recorded content, for example, while the received broadcast content is being watched, the output is interrupted in response to an incoming call by interruption and the recording is performed. When the interruption is canceled when the call ends, an inquiry is made as to whether or not the broadcast content recorded during the interruption period (interruption period) is to be played back, and the playback instruction from the user is confirmed. In terms of the, it is possible to play back the recorded content.

  In this case, when the interrupt is canceled, guidance information indicating that the mode is returned to the reception output mode is output, and when a return instruction is received in response thereto, the mode is returned to the reception output mode (claim 7). The present invention can immediately return to the state in which the current received content is output when the interrupt is released. In this case, the broadcast content recorded during the interruption period (interruption period) may be reproduced and output as necessary.

  Also, after returning to the reception output mode, guidance information indicating that the broadcast content temporarily recorded during the interruption period is in an unviewed state is output, and in response to this, a reproduction instruction for the temporary recording is output. When received, since the temporarily recorded content is reproduced and output by switching to the reproduction output mode (invention of claim 8), even when the current received content is immediately returned to the state when the interruption is canceled, It can be confirmed that there is an unviewed part, and the unviewed part can be reproduced as necessary.

Embodiments of the present invention will be described below 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, and FIG. 1 is a block diagram showing basic components of the mobile phone device.
This mobile phone device is a foldable one in which two cases (upper case and lower case) are attached so as to be openable and closable, and is driven by a secondary battery as a main power source. In addition to the connection function, a TV function that receives and outputs TV broadcast waves, a recording function that sequentially records TV broadcasts received by this TV function, and a playback function that plays back and outputs the content recorded by this recording function I have.

  The CPU 1 is a central processing unit that controls the overall operation of the mobile phone device according to various programs in the storage unit 2. The storage unit 2 is a non-volatile memory (internal memory), and is configured by, for example, a flash memory, and has a program area and a data area. In the program area, operations shown in FIGS. A program for realizing the present embodiment is stored according to the procedure. The recording medium 3 is a detachable portable memory that supplies photographed image data, various types of data, and programs to the outside. The recording medium 3 includes, for example, smart media and an IC card. The memory 4 is an internal memory having a work area, and is composed of, for example, a DRAM (Direct Random Access Memory), an SDRAM (Synchronous DRAM), or the like.

  The telephone communication unit 5 takes in a signal from the reception side of the transmission / reception duplexer connected to the antenna 6 and demodulates it into a reception baseband signal, and then outputs audio data from the audio speaker 7. In addition, the telephone communication unit 5 encodes the audio data input from the audio microphone 8 into a transmission baseband signal, and then provides the transmission baseband signal to the transmission side of the transmission / reception duplexer to transmit and output from the antenna 6. On the other hand, the display data received via the telephone communication unit 5 by the e-mail function or the Internet connection is given to the main display unit 9 such as an LCD (liquid crystal display) and displayed. The main display unit 9 displays character information, television images, various messages, and the like with high quality. FIG. 2 shows the television image displayed on the main display unit 9 in a state where the folding apparatus main body is opened. A display example of a television screen is shown. In addition to the main display unit 9, a sub display unit 10 is provided on the back of the apparatus main body, and displays the current date and time, simple messages, icons, and the like.

  The TV receiver 11 includes a TV antenna 12 and receives terrestrial digital TV broadcasts for mobile receivers such as mobile phones. In addition to TV video and audio information, an electronic program guide (EPG) is also included. It can be received. The television receiver 11 includes a dedicated CPU, a receiver connected to the TV antenna 12, an amplification / separation unit that separates and separates the received television broadcast into a video signal and an audio signal, a decoding unit that decompresses the compressed data, and the like. The TV video signal output from the TV receiver 11 is output from the main display unit 9, and the TV audio signal is output from the built-in speaker 13 or the earphone 14.

The key operation unit 15 is provided with various push button type keys for performing dial input, character input, command input, etc. In addition to the TV ON / OFF key and channel switching key for the TV function, the received broadcast contents Mode switching key for arbitrarily switching between “reception output mode (normal mode)” for sequentially outputting and “playback output mode” for reproducing recorded contents according to user operation, and instructing recording (including recording) of TV broadcasts It has a recording start key, a playback key for instructing playback of recorded content, a pause key (clear key) for instructing pause of playback, a fast-forward key for instructing fast-forward playback, an end key for instructing end of playback, etc. . Each key for the television function may be a touch key arranged on the screen of the main display unit 9. The CPU 1 executes processing according to a key input signal from the key operation unit 15. The notification unit 16 includes an LED (light emitting diode) and a vibration motor including the built-in speaker 13 described above. The notification unit 16 notifies the incoming call when a call / mail is received, and is also driven when a warning alarm is given.

FIG. 3 illustrates how the “reception output mode” for receiving and outputting broadcast contents and the “reproduction output mode” for reproducing recorded contents are automatically switched when the recorded contents are reproduced while recording the broadcast contents. It is a figure for doing.
When the television receiver 11 is in operation, the CPU 1 outputs the broadcast contents received in the “reception output mode” when the interruption of the output is instructed by an incoming call or the like (T1). In response to the interruption instruction, an operation of sequentially recording the received contents thereafter is started. After that, when an interrupt release (interrupt end) is instructed due to the end of the call (T2), a chasing playback operation that plays back and outputs the recorded contents in parallel in the “playback output mode” while continuing this recording operation is started. To do.

  This chasing playback is a separate operation between the “reception output mode” and the “playback output mode”, and the chasing playback is performed in this “playback output mode”. Chasing playback is started when is instructed. In addition, when performing chasing playback, the recording content is played back and output in parallel while continuing the recording operation. However, the recording operation and the playback operation are processed in a time-sharing manner by a single CPU. Alternatively, a recording CPU and a reproduction CPU may be provided, and the recording operation and the reproduction operation may be executed in parallel by these dedicated CPUs. Recording and playback during this chasing playback are performed on the recording memory 4A in the memory 4. That is, while updating the recording position indicating the current writing address, the program data currently being broadcast is recorded in the recording memory 4A with video data and audio data, and at the same time, the recording memory 4A is updated while updating the reproduction position indicating the current read address. The recorded content is read out and reproduced (video output, audio output).

  The CPU 1 compares the current recording position with the playback position to determine whether the playback position has caught up with the recording position. When the playback position has caught up with the recording position, the playback operation is faster than the recording operation. (T3) By canceling the “reproduction output mode” and returning to the “reception output mode”, the state is switched to a state in which the reception content currently being broadcast is output. In other words, when the playback position catches up with the recording position during chasing playback, recording is stopped at that point, and automatic switching from the operating state of chasing playback to the operating state of outputting the currently received broadcast content is performed. I am doing so. When recording a television broadcast, if a recording medium 3 such as a large-capacity semiconductor memory or a small hard disk is externally connected, the recording may be performed on the recording medium 3.

  Next, the operation concept of the mobile phone device in this 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. In other words, in addition to the recording medium, an operation peculiar to this embodiment can be executed by using a program / data supplied externally via a transmission medium.

4 to 6 are flowcharts showing a television process that is started to be executed when the television receiver 11 is activated.
First, when a desired channel is selected and designated by operating a channel selection key (step S1), the CPU 1 receives the contents of the broadcast program of the designated channel from the television receiver 11 (step S2) and has received it. A “reception output mode (normal mode)” for sequentially outputting broadcast contents is selected and switched to the mode (step S3). In this state, an output operation for sequentially outputting the received broadcast contents is started (step S4). In this case, the received video data is sequentially displayed on the main display unit 9, and the audio data is sequentially output from the built-in speaker 13 or the earphone 14.

  As described above, in the state where the television program is viewed under the “reception output mode”, the CPU 1 checks whether there is an interrupt instruction for temporarily interrupting the output of the currently received television broadcast program (step S5). . In other words, it is checked whether there is an interrupt instruction that temporarily interrupts the output of the TV broadcast when a telephone call is received, or whether there is an interrupt instruction that temporarily interrupts the output of the TV broadcast at an arbitrary timing by a user operation. . If there is no such incoming interrupt / arbitrary interrupt (NO in step S5), the presence / absence of other key operations is checked (step S6). Thereafter, the process waits until there is an interrupt instruction or key operation.

  Now, when it is detected in step S6 that the key operation is present, if the operation key is a mode switching key and is switched from "reception output mode" to "reproduction output mode" (YES in step S7). 5 and FIG. 6 to be described later. For example, when a key operation such as a recording start key, a volume adjustment operation, or a brightness adjustment operation is performed (in steps S7 and S8). NO), processing corresponding to this operation key (for example, recording start, volume adjustment, etc.) is executed (step S9), and then the process returns to step S5 described above. Note that, even after the recording of the television broadcast is started, the “reproduction output mode” process shown in FIGS. In this case, automatic playback (chase playback accompanying mode switching) is performed in which the recorded content is reproduced and output while continuing the recording operation.

  On the other hand, if the CPU 1 detects an incoming interrupt or an arbitrary interrupt that temporarily interrupts the output of the currently received television broadcast program (YES in step S5), it records the subsequent received contents in response to the interrupt detection. The recording operation sequentially written in the memory 4A is started (step S10), and the output of the received broadcast content is temporarily stopped, that is, the video display from the main display unit 9 and the audio output from the built-in speaker 13 or the earphone 14 are temporarily stopped. Stop (step S11). Then, as shown in FIG. 7A, the interrupt screen indicating that the output of the received content is in a paused state is displayed and output instead of the television screen (step S12), and then this output interruption is interrupted. It is in a standby state until is released (step S13). Here, when the CPU 1 detects the end of the call (line disconnection) or detects the end operation of the output interruption, that is, if the interruption of the output interruption is canceled (YES in step S13), the CPU 1 replaces the interrupt screen described above. The menu screen is displayed and output (step S14).

  Here, the interruption period (output interruption period) from when an interruption occurs until it is canceled is the period from when there is an incoming call while watching TV to when the call ends or from the interruption operation to This is a period until the release operation is performed, and the television broadcast recording operation is continued as it is even after this period has elapsed. The menu screen has menu items of “reproduction start” instructing the start of reproduction of the recorded content and “return to reception output” instructing the return to the original state of receiving and outputting the current broadcast content. When an arbitrary menu item is selected and designated from the inside (step S15), it is checked whether this selection item is “reproduction start” (step S16). Here, when “reproduction start” is selected (YES in step S16), an interruption reproduction flag is set (step S17) to indicate that the reproduction is associated with an incoming interruption / arbitrary interruption.

  Then, the process proceeds to the “reproduction output mode” process of FIGS. 5 and 6, and the recorded content is played back (chase playback accompanying interruption) while continuing the recording operation as it is. First, the CPU 1 checks whether or not the above-described interrupt playback flag is set, that is, whether it is chasing playback accompanying an interrupt (step S21 in FIG. 5). Now, since the interrupt playback flag is set, In step S22, the latest recorded file (immediately before), that is, the recorded file generated during the current interruption period (output interruption period) is designated as a reproduction target, and the start position ( The recorded content is read from the interrupt generation position) and the playback operation is started. Then, the display is switched from the interrupt screen to the playback screen (step S29). FIG. 7B shows a chasing playback screen, and an icon indicating that chasing playback is being performed is additionally displayed below the playback screen (in the set bar area).

  In this state, whether the fast-forward key for instructing fast-forward playback has been operated (step S35 in FIG. 6), whether the clear key for temporarily stopping the playback operation has been operated (step S36), or the playback key for starting the playback operation. It is checked whether an operation has been performed (step S37) or an end key for ending the reproduction operation has been operated (step S39). If the playback key is operated (YES in step S37), the playback operation at the normal speed (substantially the same speed as the recording speed) is started (step S52), and if the fast-forward key is operated (step S52). YES in S35), fast-forward playback at a predetermined speed (for example, normal speed × 1.3 times speed) is started (step S40).

  Here, during the fast-forward playback operation, the CPU 1 compares the current recording position with the playback position, and checks whether the playback position has caught up with the recording position (playback position = recording position) (step S41). If the reproduction position is less than the recording position, the process proceeds to step S42, where it is checked whether the reproduction position has reached the recording end position, that is, whether all the contents of the recording file have been reproduced. On condition that there is no key operation (step S43), the process returns to the above-described step S41 and continues to monitor the reproduction position. Here, when the reproduction position catches up with the current recording position by fast-forward reproduction and “reproduction position = recording position” is detected in step S41, the presence / absence of an interrupt reproduction flag is checked (step S45).

  Now, since it is a case where the chasing playback accompanying the interruption is executed, the process proceeds to step S47, and the recording operation and the playback operation are stopped. Then, in order to notify the return to the “reception output mode (normal mode)”, a “return” message is popped up (step S48). FIG. 7C shows a state in which a message indicating that the chasing reproduction returns to the normal broadcast output state is displayed in the reproduction screen. Then, the interrupt reproduction flag is reset (step S49), and after the “reproduction output mode” is canceled (step S50), the process returns to step S3 in FIG. 4 to return to the original “reception output mode”.

  If the clear key (pause key) is operated before the playback position catches up with the recording position during the chasing playback operation (step S36), the current playback position is stored and held as the stop position. (Step S51). Then, since the presence of the interrupt reproduction flag is detected in the next step S45, the reproduction operation is stopped by moving to the above-described step S47. However, in the case of a pause instruction by the clear key, only the reproduction is stopped and the recording is performed. The operation is continued as it is. Thereafter, as in the case described above, a “return” message is popped up (step S48), the interrupt reproduction flag is reset (step S49), the “reproduction output mode” is canceled (step S50), and the original Return to the “reception output mode” (step S3).

  When the chasing reproduction is paused in this way and then the restart is instructed, the mode switching key is operated. As a result, when the “reception output mode” is switched to the “reproduction output mode”, YES is determined in step S7 in FIG. 4 and the processing of the “reproduction output mode” starts. In this case, NO is determined in steps S21 and S23 in FIG. 5 and the process proceeds to step S24 to display a list of recording files that have been recorded and stored and managed in the memory 4 or the like up to the present time. In this case, a list of file names is displayed, and when a desired file is selected and designated from the list screen (step S25), whether or not the previous stop position is stored and held corresponding to this selected file, that is, Then, it is checked whether the reproduction operation is resumed after being paused (step S26). Now, it is restart after interruption, and since the previous stop position is associated with this interruption file, the reproduction operation is started (restarted) from this position (step S27). And after switching to a reproduction | regeneration screen, it moves to step S35 of FIG. 6, and the above-mentioned operation | movement is repeated hereafter.

  Here, when the CPU 1 finishes reproducing all the contents of the recording file by fast-forward reproduction and the reproduction position reaches the recording end position (YES in step S42 in FIG. 6), the reproduction operation is stopped at this point (step S44). . If the playback position reaches the recording end position by playback at normal speed (YES in step S38) or if the end key for instructing playback end is operated (YES in step S39), playback is performed at this time. The operation is stopped (step S53).

  Then, the process goes to step S23 in FIG. 5 to check whether or not the temporary recording flag is set. However, since the chasing playback accompanying the interruption is currently being performed, the process goes to step S24 to display a list of recorded files. In this case, in order to instruct playback of another recorded file following chasing playback accompanying interruption, a desired file may be selected as a new playback target from this list display, but the playback operation is terminated as it is. If the end key is operated to make it happen (YES in step S31), the “reproduction output mode” is canceled (step S32). Then, the process returns to step S3 in FIG. 4 to return to the “reception output mode”.

  On the other hand, when the mode switching key is operated to switch to the “reproduction output mode” during the recording of the television broadcast (YES in step S7), the chasing reproduction accompanying the mode switching is executed. Here, when the “reproduction output mode” process of FIGS. 5 and 6 is entered, the recorded files are displayed in a list (step S24 in FIG. 5). Since a new file is selected as a reproduction target (step S26), the reproduction operation is started from the head position of the selected file (step S28). Then, after switching to the reproduction screen (step S29), the process proceeds to step S35 in FIG. In this case, when the playback position catches up with the current recording position (step S41), since no interrupt playback flag is detected in the above-described step S45, the process proceeds to step S46, and when the playback position catches up with the recording position. After the reproduction operation is paused, the process returns to step S35. In this case, the playback operation can be resumed from the stop position by operating the fast-forward key or the playback key with a slight delay after the pause.

  On the other hand, when “return to reception output” is selected from the menu screen described above (NO in step S16 in FIG. 4), the recording operation is terminated at this point (step S18) and within the interruption period. A temporary recording flag indicating that there is a temporarily recorded broadcast content (recorded content not yet viewed) is set (step S19). Then, after an icon indicating the presence of temporary recording is displayed in the vicinity of the television screen (step S20), the process returns to the above-described step S3 to return to the “reception output mode”. FIG. 7D is a diagram showing an icon display example with temporary recording. This icon display is displayed on the lower side (set bar area) of the television screen, and this icon display area constitutes a touch button. When the area is touch-designated as necessary (step in FIG. 4). YES in S6), the process proceeds to the “reproduction output mode” process of FIGS. 5 and 6 described above.

  In this case, since the presence of the temporary recording flag is detected in step S23 of FIG. 5, the immediately preceding recording file, that is, the file recorded during the interruption period (recording file for unviewed) is designated as the reproduction target, The reproduction operation is started from the head position of the designated file (step S30). Then, the process proceeds to step S35 in FIG. In this case, since the playback of the unviewed recording file is not the follow-up playback in which the playback is performed in parallel with the recording, step S41 for comparing the playback position and the recording position during the fast-forward playback operation is skipped.

  When all the contents of the unviewed recording file have been reproduced and the reproduction position reaches the recording end position of the file (step S38), or the end key for instructing the reproduction end is operated (step S39). Although the reproduction operation is stopped (step S53), the temporary recording flag is reset (steps S54 and S55). Then, the process proceeds to step S23 in FIG. 5, but since the temporary recording flag is reset at this point, the process proceeds to step S24. If the end key is operated (step S31), the “reproduction output mode” is canceled (step S32), and the process returns to the “reception output mode” (step S3).

  As described above, in this embodiment, the CPU 1 performs the recording operation when the reproduction of the recorded content is instructed during the recording operation in which the broadcast content received by the television receiver 11 is written in the recording memory 4A. In the “reproduction output mode”, the recording contents are sequentially read out from the recording memory 4A, and the chasing reproduction in which the reproduction is output in parallel is started, and the current recording position and the reproduction position are compared during the chasing reproduction operation. However, when the playback position catches up with the recording position, it is switched to the state where the current broadcast content is received and output by canceling the “playback output mode” and returning to the “reception output mode”. Even if the playback position catches up with the recording position in the middle of playback, smooth playback from the chase playback to the reception output during the current broadcast without any special operation Can be transferred to Seamless), even In the viewer has switched to receive the output of the currently broadcast from chasing playback, it is possible to watch concentrating broadcast content to its end.

  In this case, when the playback position catches up with the recording position during chasing playback, a message is displayed in the playback screen to pop up the playback screen to return to the normal broadcast output state `` reception output mode ''. It is possible to return to the “reception output mode” after allowing the user to confirm the automatic switching. Also, when the clear key is operated during the chasing playback operation, the "playback output mode" is canceled and the "reception output mode" is restored so that the playback position can catch up with the current recording position. If necessary, it is possible to return to the “reception output mode”, and the convenience can be increased.

  When the CPU 1 cancels the playback output mode and returns to the “reception output mode” during the chasing playback operation, the recording operation is terminated in addition to stopping the playback operation at that time. Recording can be prevented and wasteful power consumption can be suppressed. In addition, in the state where the received content is being output sequentially under “Receiving output mode”, in response to the output interruption interrupt instruction, the operation to sequentially record the subsequent received contents is started, and then this interrupt release instruction In response, the menu screen prompting that the recorded content should be played back is displayed, and when the “playback start” item is selected accordingly, the playback starts from the beginning of the recorded content. Therefore, it is possible to play back the recorded content after inquiring whether or not the broadcast content recorded during the interruption period (interruption period) is to be played back and after confirming the playback instruction from the user.

  Here, in the menu screen that is displayed when the interrupt is released, a menu item of “reception return” indicating that it is possible to return to “reception output mode” is displayed. When is selected, since the mode is returned to the “reception output mode”, it is possible to immediately return to the state of outputting the current reception content when the interrupt is released. In this case, the broadcast content recorded during the interruption period (interruption period) may be reproduced and output as necessary. In other words, when the “Receive Receipt” menu item is selected, a temporary recording icon indicating that there is an unviewed temporary recording file is displayed as a guide. When the playback instruction is received, the content of the unrecorded temporary recording file is played back by switching to the “playback output mode”. It can be confirmed that there is an unviewed part, and the unviewed part can be reproduced as necessary.

  In the above-described embodiment, as shown in FIG. 8C, the user is confirmed to automatically switch the mode by guiding and displaying a message to return from the chasing playback state to the normal broadcast output state. Whether to return to the “reception output mode” may be inquired in a YES / NO format, and switched to the “reception output mode” in accordance with an instruction to the inquiry. In this case, prior confirmation may be performed by displaying this inquiry screen before the playback position catches up with the current recording position (for example, one minute before).

In the above-described embodiment, the normal speed can be switched to the high speed by the fast-forward key. However, the normal speed reproduction and the fast-forward reproduction are performed according to the interruption time after the interruption is generated until the interruption is canceled. Automatic switching may be performed. For example, if the interruption time is below a certain standard, reproduction at normal speed may be started, and if it exceeds a certain standard, fast-forward reproduction may be started. Further, as the interruption time becomes longer, the fast-forwarding speed may be increased stepwise such as 1.2 times and 1.3 times.
In addition, the present invention is not limited to a mobile phone device with a TV function, and can be similarly applied to a mobile terminal device such as a PDA with a TV function, an electronic camera, an electronic watch, a music player, etc. It may be a receiver.

  On the other hand, a recording medium (for example, a CD-ROM, a flexible disk, a RAM card, etc.) on which program codes for executing the above-described units are recorded may be provided to the computer. That is, a computer-readable recording medium having a program code, and a function of arbitrarily switching between a reception output mode for sequentially outputting received broadcast contents and a reproduction output mode for reproducing recorded contents according to a user operation; A function of executing chasing playback to reproduce and output the recorded content in parallel in the playback output mode while continuing the recording operation when an instruction to reproduce the recorded content is given during recording of the received broadcast content; In this chasing playback operation, the current recording position is compared with the playback position to determine whether the playback position has caught up with the recording position, and it has been determined that the playback position has caught up with the recording position. When switching to a state in which the current broadcast content is received and output by canceling the reproduction output mode and returning to the reception output mode. Preparative may be provided a recording medium readable recorded computer programs for realizing.
