Description

  The present invention relates to a portable terminal device with a television function and a program for receiving and outputting television broadcast radio waves.

2. Description of the Related Art Conventionally, portable terminal devices with a TV function for receiving and outputting TV broadcasts have become widespread. This type of mobile terminal device has a recording function for receiving and recording a TV broadcast. When a telephone call is received while watching TV, recording of the broadcast content is started, and recording is performed after the call ends. There is known a technique having a function of sequentially reproducing and outputting recorded contents from the start position while continuing the so-called chasing playback function (see Patent Document 1).
JP 2002-247490 A

  However, this type of technology reproduces and outputs the broadcast content that is currently being recorded, but it is suitable for portable terminal devices that have extremely small recording memory capacity compared to stationary recording devices. As a result, the recording memory may become full (recording difficult state) for some reason during the chasing playback operation. This is not limited to after the start of chasing playback, but after recording starts, the time until chasing playback starts, that is, when the call time is long, only recording proceeds. There is a high possibility that the recording memory will be full. In such a case, the recording operation is stopped, but the subsequent broadcast content cannot be recorded (viewed) by this recording stop. In this case, when the recording is stopped, the viewer may perform a switching operation to cancel the chasing playback and output the current broadcast contents. However, if the recording is not noticed, the chasing playback is performed with the recording stopped. As a result, the broadcast content after the recording stop cannot be viewed.

  SUMMARY OF THE INVENTION An object of the present invention is to make it possible to quickly cope with a decrease in the recordable remaining amount that can be recorded in the recording memory during the chasing playback operation.

The invention described in claim 1 is a portable terminal device with a TV function for receiving and outputting a TV broadcast radio wave, and continuously storing the received broadcast contents in the recording memory while continuing the recording operation. Chasing playback means for reproducing and outputting in parallel, and whether or not it has become difficult to continue recording due to a decrease in the recordable remaining amount that can be recorded in the recording memory during the playback operation by the chasing playback means Discriminating means for discriminating the content, and when the discriminating means discriminates that it is difficult to continue recording, the recording operation is stopped, and the received content currently being broadcast is substituted for the chasing playback output. And a control means for switching to the output.
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 10).

The invention described in claim 1 described above may be as follows.
At the time of the chasing playback, the recording position is updated every time the received broadcast content is sequentially stored in the recording memory, and the playback position is updated every time the content of the recording memory is sequentially played back. In a state where the operation of returning the recording position or the playback position to the start position of the recording memory is cyclically repeated every time the playback position reaches the end position of the recording memory, the discriminating means approaches the recording position to the playback position. Alternatively, it is determined whether or not it has become difficult to continue recording based on whether or not they match (invention of claim 2).

  The control means issues an alarm notification that it is difficult to continue recording prior to stopping the recording operation (the invention according to claim 3).

The invention according to claim 4 is a portable terminal device with a TV function for receiving and outputting a TV broadcast radio wave, and continuously storing the received broadcast content in the recording memory while continuing the recording operation. Chasing reproduction means for reproducing and outputting in parallel, and determination means for determining whether or not the recordable remaining amount that can be recorded in the recording memory approaches the limit during the reproduction operation by the chasing reproduction means; When it is determined that the recordable remaining amount has approached the limit by this determination means, the chasing playback is started at a speed equal to or higher than the recording speed while continuing the recording. And control means for controlling the recording operation so that the received broadcast content can be recorded.
Furthermore, a program for realizing the main functions shown in the invention described in claim 4 is provided to the computer (the invention described in claim 11).

The invention described in claim 4 described above may be as follows.
At the time of the chasing playback, the recording position is updated every time the received broadcast content is sequentially stored in the recording memory, and the playback position is updated every time the content of the recording memory is sequentially played back. In a state where the operation of returning the recording position or the playback position to the start position of the recording memory is cyclically repeated every time the playback position reaches the end position of the recording memory, the discriminating means approaches the recording position to the playback position. Whether the recordable remaining amount has approached its limit is determined based on whether or not the recording has been performed (the invention according to claim 5).

  The control means issues an alarm notification that the recordable remaining amount has approached its limit prior to the speed-up of the chasing playback (the invention according to claim 6).

  When it is determined that the recordable remaining amount has approached the limit by the determining unit, the state is identified and displayed while the limit is approaching (the invention according to claim 7).

The invention described in claim 8 is a portable terminal device with a television function for receiving and outputting a television broadcast radio wave, and continuously storing the received broadcast content in the recording memory while continuing the recording operation. A chasing playback means for playing back and outputting in parallel; a discriminating means for discriminating whether or not the remaining recordable amount that can be recorded in the recording memory is reduced during the playback operation by the chasing playback means; And a notification means for performing an alarm notification when it is determined by the means that the remaining recordable amount is low.
Furthermore, a program for realizing the main functions shown in the invention described in claim 8 is provided to the computer (the invention described in claim 12).

  The above-described invention according to claim 8 updates the recording position each time the received broadcast content is sequentially stored in the recording memory at the time of the follow-up reproduction, and every time the content of the recording memory is sequentially reproduced. In addition to updating the playback position, in addition to cyclically repeating the operation of returning the recording position or the playback position to the start position of the recording memory every time the recording position or the playback position reaches the end position of the recording memory, The discriminating means may discriminate whether or not the recordable remaining amount has decreased based on whether or not the recording position has approached the playback position (the invention according to claim 9).

  According to the first aspect of the present invention, the recording operation is stopped when it becomes difficult to continue the recording due to a decrease in the remaining recordable amount during the operation of the chasing playback while recording the received broadcast content. In addition, instead of chasing playback output, it is switched to the output of the currently broadcasted reception content, so that the recorded content up to that time will be viewed later, first the current broadcast content can be viewed As a result, it is possible to surely prevent missed contents from being received quickly.

  According to the invention described in claim 2, in addition to the same effect as the invention described in claim 1, the recording position is updated and the playback position is updated at the time of chasing playback, and the recording position or the playback position is recorded. Recording is performed based on whether the recording position approaches or coincides with the playback position while cyclically repeating the operation of returning the recording position or playback position to the start position of the recording memory every time the end position of the memory is reached. Since it has been determined whether or not it has become difficult to continue, it is possible to easily recognize whether or not it is difficult to continue recording simply by monitoring and comparing the recording position and the playback position. .

  In other words, in chasing playback, the recording position precedes the playback position, and generally the chasing playback advances so that the playback position catches up with the recording position. When an operation such as slow playback or temporary playback stop is performed, playback is slower than recording and the recording position follows the playback position. Here, when the recording position approaches the reproduction position, the remaining recordable amount is only between the recording position and the reproduction position, and becomes extremely small, and continuous recording becomes difficult. Therefore, it is possible to recognize whether or not continuous recording is difficult by comparing the recording position with the reproduction position and monitoring whether the recording position has approached the reproduction position.

  According to the invention described in claim 3, in addition to having the same effect as that of the invention described in claim 1, the alarm notification is made that it is difficult to continue the recording before the recording operation is stopped. Therefore, it is possible to know in advance that a situation in which it is necessary to forcibly switch to the output of the reception content currently being broadcast during the recording operation.

  According to the fourth aspect of the present invention, for example, after recording the capacity of the recording memory in the recording memory, the newly received broadcast content is overwritten in the reproduced area of the recording memory, so that the entire area of the recording memory is recorded. In the case of full use, the remaining recording capacity may approach the limit during playback depending on the state of chasing playback (temporary playback stopped, slow playback, etc.). In addition to starting chasing playback at a speed higher than this recording speed while continuing, the recording operation is controlled so that the newly received broadcast content can be recorded in the part that has been chased and played back. Automatic adjustment can ensure that the remaining recordable amount is increased, and this quick response makes it possible to continue recording.

  According to the invention described in claim 5, in addition to having the same effect as the invention described in claim 4 described above, the recording position is updated at the time of chasing playback, and the playback position is updated. Recording can be performed based on whether or not the recording position has approached the playback position while cyclically repeating the operation of returning the recording position or playback position to the start position of the recording memory every time the end position of the recording memory is reached. Since it is determined whether or not the remaining amount has approached its limit, it is easy to recognize whether or not the remaining recordable amount has approached that limit simply by monitoring and comparing the recording position and the playback position. It becomes possible. In this case, for example, even if the recording position approaches the playback position due to slow playback, temporary playback stop, etc., it is possible to ensure an increase in the remaining recordable amount by increasing the playback speed.

  According to the invention described in claim 6, in addition to the same effect as that of the invention described in claim 4 above, an alarm notification is given that the remaining recordable capacity has approached its limit prior to the increase in the speed of chasing playback. Therefore, it is possible to prevent the playback speed from being automatically adjusted without any notice.

  According to the invention described in claim 7, in addition to having the same effect as that of the invention described in claim 4 described above, when it is determined that the remaining recordable capacity approaches the limit, Since the state is identified and displayed, an emergency situation can be avoided by instructing fast-forward playback or the like.

  According to the eighth aspect of the present invention, for example, after recording the capacity of the recording memory in the recording memory, the newly received broadcast content is overwritten and recorded in the replayed area of the recording memory. In such a case, the remaining recordable amount may decrease during playback depending on the state of chasing playback (temporary playback stopped, slow playback, etc.). Therefore, this quick response is possible, and the user pays attention to the speed of chasing playback, that is, playback and watching while paying attention such as not repeating slow playback or repeating pause temporarily. Can be enjoyed continuously.

  According to the ninth aspect of the present invention, in addition to having the same effect as that of the above-described eighth aspect of the invention, the recording position is updated and the reproduction position is updated at the time of chasing reproduction. Recording is performed based on whether or not the recording position has approached the playback position while cyclically repeating the operation of returning the recording position or playback position to the start position of the recording memory every time the recording memory reaches the end position of the recording memory. Since it is determined whether or not the remaining recordable amount has decreased, it is possible to easily recognize whether or not the recordable remaining amount has decreased by simply monitoring and comparing the recording position and the playback position. . In this case, for example, even if the recording position approaches the playback position due to slow playback, temporary playback stop, etc., if the user increases the playback speed by alarm notification or cancels the temporary playback stop, It is possible to ensure an increase.

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.

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, and performs dial input, character input, command input, etc. In addition to a TV ON / OFF key and a channel switching key for TV functions, it records TV broadcasts. A recording start key for instructing (including recording), a playback key for instructing playback of the recorded content, a pause key for instructing pause of playback, a fast-forward key instructing fast-forward playback, an end key instructing the end of playback, etc. Have. 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 is a diagram for explaining chasing playback in which the contents of the recording memory 4A are reproduced and output in parallel while continuing the recording operation of sequentially storing the received TV broadcast program contents in the recording memory 4A in the memory 4. is there.
In this embodiment, during the viewing of a television broadcast, an interruption occurs (for example, detection of an incoming call), the viewing is temporarily interrupted to start a recording operation, and a recording operation is continued when the interruption ends (for example, detection of a telephone interruption). In addition, chasing playback for reproducing and outputting the recorded contents in parallel is started.

The recording operation and the reproducing operation at the time of the chasing reproduction are performed using the recording memory 4A. At this time, the CPU 1 updates the recording position WP indicating the current writing address while updating the contents of the program currently being broadcast (video). (Data, audio data) are recorded and stored in the recording memory 4A, and the recording contents are sequentially read out from the recording memory 4A while updating the reproduction position RP indicating the current readout address, and are reproduced and output (video output, audio output).
The recording memory 4A has a capacity capable of continuous recording (including audio) for 20 minutes, for example, by overwriting recording the newly received broadcast content in the replayed area of the recording memory 4A. The entire area of the recording memory 4A is fully utilized. Further, when a recording medium 3 such as a large-capacity semiconductor memory or a small hard disk is externally connected when receiving and recording a television broadcast, the recording may be performed on the recording medium 3. In the embodiment, recording is stored in the recording memory 4A.

  In this case, in the chasing playback, as shown in FIG. 3A, the recording position WP precedes the playback position RP, and when the recording position WP reaches the end position of the recording memory 4A, the CPU 1 As shown in B), the recording position WP is returned to the head position of the recording memory 4A. When the playback position RP reaches the end position of the recording memory 4A, the playback position RP is returned to the head position of the recording memory 4A as shown in FIG. By repeating such an operation cyclically, the chasing playback is performed while continuing the recording operation. In this case, after the recording for the capacity is performed in the recording memory 4A, the newly received broadcast content is overwritten in the reproduced area of the recording memory 4A. In the figure, the area from the recording position WP to the reproduction position RP in the direction of the arrow (forward direction) (outlined part in the figure) is an area where recording can be performed (recordable remaining amount). . Further, the area from the playback position RP to the recording position WP (shaded area in the figure) is an unreproduced recording area (unreproduced recording amount), and an unrecordable area that cannot be recorded over this part. It becomes.

  In general, in chasing playback, when the recording position WP precedes the playback position RP, the playback position RP approaches the recording position WP as shown in FIG. It catches up with the position WP. On the other hand, when an operation such as slow playback or temporary playback stop is performed, playback is slower than the recording speed, and the recording position WP follows the playback position RP. Here, as shown in FIG. 3E, when the recording position WP approaches the reproduction position RP, that is, when the amount of unreproduced recording increases and approaches the capacity of the recording memory 4A, the recordable area (recordable remaining area). Amount) is only between the recording position WP and the reproduction position RP, and is extremely small.

  Thus, during the chasing playback operation, the CPU 1 determines whether or not the unreproduced recording amount has approached the capacity of the recording memory 4A based on whether or not the recording position WP has approached the reproduction position RP, in other words, recording is possible. If the remaining capacity is approaching the limit (whether continuous recording has become difficult) or if the remaining recordable capacity is approaching the limit and it is determined that it is difficult to continue recording, In addition to notifying the alarm, the recording operation is stopped at this point, and the output of the reception content currently being broadcast is switched instead of the output of the chasing playback, or the fast-forward playback is temporarily switched.

  Next, the operation concept of the cellular phone device with a television function 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 7 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. Broadcast content output is started (step S3). In this case, the received video data is sequentially displayed and output from the main display unit 9, and the audio data is sequentially output from the built-in speaker 13 or the earphone 14.

  In a state where the broadcast content of the television program is output (viewed) in this way, the CPU 1 checks whether there is an interrupt instruction for temporarily interrupting the output of the currently received television broadcast program (step S4). 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 S4), the presence / absence of other key operations is checked (step S11), and the process waits until there is an interrupt instruction or key operation.

  Here, when an incoming interrupt or an arbitrary interrupt that temporarily interrupts the output of the currently receiving television broadcast program is detected (YES in step S4), the CPU 1 responds to the detection of the interrupt, The recording operation of sequentially writing from the head position of the recording memory 4A is started (step S5), and the output of the received broadcast content is temporarily stopped, that is, the video display from the main display unit 9 and the sound from the built-in speaker 13 or the earphone 14 The output is temporarily stopped (step S6). Then, after 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 S7), whether or not the output interruption interrupt is released (whether the interrupt ends) Is checked (step S8).

  That is, it is checked whether a call end (line disconnection) or an output interruption end operation is detected. If no interrupt end is detected, the process proceeds to step S10, and whether the recording position WP approaches the playback position RP. Based on whether or not, it is checked whether the unreproduced recording amount approaches the capacity (MAX) of the recording memory 4A. That is, in this case, only the recording operation is performed and the reproduction operation is not performed. Therefore, in step S10 described above, it is checked whether the recording has been performed up to the capacity (MAX) of the recording memory 4A. Here, when the unreproduced recording amount approaches the capacity (MAX) of the recording memory 4A, in other words, when recording is performed up to the capacity of the recording memory 4A (YES in step S10), FIG. Then, the flow goes to step 5 to perform alarm notification for outputting an alarm sound from the notification unit 16 (built-in speaker 13) (step S14).

  In other words, when an interruption occurs during TV broadcast viewing (detection of incoming phone call) and the recording operation is started by temporarily suspending the viewing, the interruption period (call time) is too long and continuous recording becomes difficult. When this happens, an alarm is notified. And a menu screen is displayed on the main display part 9 (step S15). This menu screen has items of “1: chasing playback” and “2: resumption of reception output”. When any menu item is selected (step S16), the selected menu is determined (step S17). .

  “1: Chasing playback” is a menu item for instructing the start of chasing playback in which playback operations for sequentially playing back the recorded contents while continuing the recording operation are performed. This is a menu item indicating that the reproduction is canceled and the currently broadcasted reception content is output (viewed). Here, when “1: chasing playback” is selected (NO in step S17), the flow proceeds to the flow of FIG. 7 to start chasing playback, but when “2: reception output restart” is selected. Terminates the recording operation at this time (step S18), and sets a temporary recording flag indicating that broadcast content temporarily recorded by interruption (recorded content for unviewed) exists (step S18). S19). Then, an icon indicating that there is a temporary recording is displayed on the television screen for guidance (step S20), and after the operation of outputting the reception content currently being broadcast is restarted (step S21), the process returns to step S4 in FIG.

  If the icon indicating the presence of temporary recording displayed on the television screen is selected and designated (YES in steps S11 and S12 in FIG. 4), the process proceeds to the flow in FIG. 6 and the normal playback operation is started. Let That is, the CPU 1 accesses the recording file corresponding to the selected icon, reads the recording contents from the head position, and starts the reproduction (step S22). During the reproduction operation, the presence or absence of key operation is checked (step S23). When a key other than the key indicating the reproduction end is operated (NO in step S24), for example, fast-forwarding is performed as a process corresponding to the operation key. Processing such as playback, slow playback, normal playback, and temporary playback stop is performed (step S26). When a key operation indicating the end of playback is performed (YES in step S24) or when all the recorded files have been played back (YES in step S26), the playback operation is terminated at this point ( Step S27). Then, the temporary recording flag is reset (step S28), the display of the selected temporary recording icon is deleted (step S29), and the process returns to the first step S1.

In addition, in steps S11 and S12 in FIG. 4, when it is detected that a key operation such as a recording start key, a volume adjustment operation, or a brightness adjustment operation is performed as other keys, processing corresponding to the operation key is performed. For example, after executing processing such as recording start and volume adjustment (step S13), the process returns to the first step S1.
On the other hand, if the end of interruption is detected by the end operation of the call (line disconnection) or the output interruption before the unreproduced recording amount approaches the capacity (MAX) of the recording memory 4A (YES in step S8), the interruption After setting the end flag (step S9), the flow proceeds to the flow of FIG. 7 and chasing playback is started. The interruption period (output interruption period) from when an interrupt occurs until it is canceled is the period from when a call is received while watching TV until the call ends, or from the interruption operation. This is a period until the operation is performed, and the television broadcast recording operation is continued as it is even after this period has elapsed (after the chasing playback).

  Now, when chasing playback is started, the recorded contents are sequentially read from the head position of the recording memory 4A, the video data is displayed and output from the main display unit 9, and the audio data is output from the built-in speaker 13 or the earphone 14 ( Step S30 in FIG. It is checked whether any key operation is performed during the chasing playback operation (step S31). When the chasing playback end operation is performed (YES in step S32), the process proceeds to step S48 to stop the playback operation. However, when other keys are operated, for example, fast-forward playback, slow playback, normal playback, and temporary playback stop are performed as processing corresponding to the operation keys (step S33).

  Further, at the detection timing without key operation (NO in step S31), the process proceeds to step S34, and in the same manner as described above, whether or not the unreproduced recording amount has approached the capacity (MAX) of the recording memory 4A, that is, As shown in FIG. 3E, it is checked whether or not the playback operation has become slower than the recording speed due to the above-described slow playback or temporary playback stop, and the recording position WP has approached the playback position RP. Here, when the unreproduced recording amount approaches MAX in the recording memory 4A, it is checked whether or not the interrupt end flag is set (step S35). Since the interrupt end flag is now set, an alarm is generated. An alarm notification for outputting a sound from the notification unit 16 (built-in speaker 13) is performed (step S36), and a menu screen is displayed on the main display unit 9 (step S37). This menu screen has items of “1: fast forward playback → normal playback” and “2: resume reception output”, and when any menu item is selected (step S38), the selected menu is determined (step S38). Step S39).

  This “1: fast forward playback → normal playback” is a menu item indicating that the normal playback (recording speed) is automatically switched to normal playback after fast forward playback for a predetermined time. Here, although the predetermined time depends on the capacity of the recording memory 4A, etc., for example, it is 5 seconds, and the fast-forward speed is, for example, 1.5 times that of normal reproduction. “2: Resumption of reception output” is a menu item indicating that the chasing reproduction is canceled and the reception content currently being broadcast is output (viewed). Here, if “1: fast forward playback → normal playback” is selected (NO in step S39), for example, 1.5 times fast forward playback is started (step S41). In this case, audio is fast-forwarded together with video fast-forward. When the elapse of a predetermined time (for example, 5 seconds) from the fast-forward playback is detected, the fast-forward playback is switched to the normal playback (step S42). Although an emergency situation can be temporarily avoided by such fast-forward playback, the unreproduced recording amount is still close to the limit, so a limit icon for informing that is displayed in the playback screen (step S43).

  Thereafter, the process returns to step S31. Here, when the user who has confirmed the limit icon performs a key operation for instructing fast-forward playback (steps S31 and S32), for example, fast-forward playback of 1.3 times or 1.5 times is performed. Although this is performed (step S33), the playback operation becomes faster and if the playback progresses considerably, the amount of unplayed recording is reduced. Therefore, in step S34 described above, “NO” is determined, and the process proceeds to step S44. It is checked whether the recording amount is 1/3 or more of the entire capacity of the recording memory 4A. Now, although the unreproduced recording amount is not close to the capacity (MAX) of the recording memory 4A, if it is 1/3 or more, a caution icon for informing that is displayed on the reproduction screen (step S45). ). And it returns to above-mentioned step S31 and checks the presence or absence of key operation.

  If the unreproduced recording amount is less than 1/3 of the total capacity of the recording memory 4A (NO in step S44), the process proceeds to step S46. In this case, the limit icon and the caution icon described above are displayed as guidance. In this case, a process for deleting the display of the icon is performed. Then, it is checked whether there is an unreproduced recording amount, that is, whether the reproduction position RP has approached the recording position WP and finally has caught up to the recording position WP (step S47). If any unreproduced recording amount remains (NO in step S47), the process returns to the above-described step S31. However, if the reproduction position RP catches up with the recording position WP, the chasing reproduction is stopped at this point. After making it (step S48), the process returns to the first step S1.

  On the other hand, when the unreproduced recording amount approaches the capacity (MAX) of the recording memory 4A and the menu screen is displayed, when “2: resume reception output” is selected during recording before chasing playback ( In step S17 of FIG. 5, the recording operation is terminated at this point (step S18), and a temporary recording flag indicating that broadcast content temporarily recorded by interruption (recording content for unviewed) exists. Is set (step S19). Then, an icon indicating the presence of temporary recording is displayed in the vicinity of the television screen (step S20), and after the operation of outputting the reception content currently being broadcast is restarted (step S21), the process returns to step S4 in FIG. .

  If “2: Resuming reception output” is selected from the menu screen during the chasing playback operation (YES in step S39 in FIG. 7), chasing playback is stopped (step S40). Moving to the flow of FIG. 5, the recording operation is terminated (step S18) and the temporary recording flag is set (step S19) as in the case described above. Then, an icon indicating the presence of temporary recording is displayed in the vicinity of the television screen (step S20), and after the operation of outputting the reception content currently being broadcast is restarted (step S21), the process returns to step S4 in FIG. .

  As described above, in this embodiment, the CPU 1 continues the recording operation for sequentially storing the received broadcast contents in the recording memory 4A, while performing the follow-up reproduction operation for reproducing and outputting the contents of the recording memory 4A in parallel. Based on whether or not the unreproduced recording amount has approached the capacity of the recording memory 4A, it is determined whether or not the remaining recordable amount has approached the limit, that is, whether or not it has become difficult to continue recording, When the remaining recording capacity approaches the limit and it becomes difficult to continue recording, this recording operation is stopped and chased on the condition that “2: resume reception output” is selected and specified from the menu screen. Instead of playing, the output of the currently received content is resumed, so even if continuous recording becomes difficult during this chasing playback operation, the output of the currently received content is immediately output. Cut off Can be replaced. Therefore, the recorded content up to that time is viewed later, so that the current broadcast content can be viewed first, and it is possible to surely prevent the received content from being missed by a quick response.

In this case, the CPU 1 updates the recording position WP and the reproduction position RP at the time of chasing reproduction, and records the recording position WP or the reproduction position RP every time the recording position WP or the reproduction position RP reaches the end position of the recording memory 4A. Whether or not the unreproduced recording amount has approached the capacity of the recording memory 4A based on whether or not the recording position WP has approached the reproduction position RP in a state where the operation of returning to the head position of the memory 4A is cyclically repeated. Therefore, it is possible to easily and surely recognize whether or not it has become difficult to continue recording only by monitoring and comparing the recording position WP and the reproduction position RP.
Also, since it will be alarmed that it is difficult to continue recording prior to canceling the recording operation, it is necessary to foresee that it has become necessary to forcibly switch to the output of the reception content currently being broadcast. I can know.

The CPU 1 displays and outputs a menu screen when the recordable remaining amount approaches the limit during the chasing playback operation and it becomes difficult to continue recording. From this menu screen, “1: fast forward playback → normal playback” is displayed. In addition to starting the chasing playback at a speed higher than the recording speed while continuing to record on the condition that is selected and specified, the recorded content can be recorded so that the newly received broadcast content can be recorded in the chased playback portion. Since the operation is controlled, it is possible to automatically adjust the playback speed, and by this adjustment, it is possible to secure an increase in the recordable remaining amount, and it is possible to continue recording by this quick response.
In this case, since the alarm notification is made that the remaining recordable capacity is approaching its limit before the chasing playback speed is increased, it is possible to prevent the playback speed from being automatically adjusted without any notice. it can. In addition, since a limit icon indicating that the remaining recordable amount has approached the limit is displayed as a guide, an emergency situation can be avoided by instructing fast-forward playback or the like.

  Further, during the chasing playback operation, the CPU 1 determines whether or not the recordable remaining amount that can be recorded in the recording memory 4A has decreased (whether or not it is 1/3 or less). Since the alarm notification that displays a caution icon is performed when the volume decreases, this quick response is possible, and the user pays attention to the speed of chasing playback, that is, slow playback Can be enjoyed continuously while paying attention not to repeat or pause playback.

  In the embodiment described above, it is checked whether or not the unreproduced recording amount has approached the capacity (MAX) of the recording memory 4A based on whether or not the recording position WP has approached the reproduction position RP. In this case, it is determined whether or not continuous recording becomes difficult due to approaching the limit, but the remaining recordable amount is detected and the remaining recordable amount approaches the capacity (MAX) of the recording memory 4A. It may be determined based on whether or not it has become a situation where continuous recording is difficult.

In the embodiment described above, it is determined whether or not the remaining recordable amount has decreased based on whether or not the unreproduced recording amount is 1/3 or more of the capacity of the recording memory 4A. It may be determined whether or not the recordable remaining amount has decreased by detecting the remaining amount and comparing it with the capacity of the recording memory 4A.
In the above-described embodiment, it is determined whether or not it is difficult to continue recording based on whether or not the recording position WP has approached the reproduction position RP. However, the recording position WP becomes the reproduction position RP. It may be determined whether or not it has become difficult to continue recording based on whether or not they match.

  In the above-described embodiment, when the remaining recording capacity approaches the limit and it becomes difficult to continue recording, this recording is performed on the condition that “2: resume reception output” is selected and specified from the menu screen. While stopping the operation and restarting the output of the reception content currently being broadcast instead of the chasing playback, the recording operation is performed without displaying the menu screen, that is, without selecting and specifying “2: Resuming reception output”. May be canceled. Similarly, on the condition that “1: fast forward playback → normal playback” is selected and specified from the menu screen, this fast forward chasing playback is started while continuing the recording, but without displaying the menu screen. That is, fast-forward playback may be performed without selecting and specifying “2: Resume reception output”.

In the above-described embodiment, the caution icon and the limit icon are guided and displayed, but the caution message and the limit message may be guided and displayed instead of the icon display.
In addition, the embodiment described above 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 wristwatch, or a music player. .
