  By the way, it seems that there is almost no illusion that the video on the TV screen is a real-time video that is currently being broadcast when a TV program that has been broadcast late at night is recorded and watched in the morning. However, when a video for chasing playback is displayed on the television screen, there is a high possibility that the video is a real-time video, and there is a possibility that the chasing playback state will remain indefinitely. For example, when you are watching a program that is currently being broadcast in real time, if there is an incoming call, it will switch to automatic recording, but when the call ends a few minutes later, chasing playback will start and the TV screen will appear. Is delayed for a few minutes, but even if you get away from the TV screen when you receive an incoming call and pay attention to the TV screen after the call ends, the video on the TV screen is currently delayed by a few minutes. There was a possibility that the program being broadcast was illusioned to be real-time video, and it was possible to continue to watch the playback.

  In such chasing playback, it is preferable to switch to real-time video after regaining a delay of several minutes by fast-forward playback, but if you keep chasing playback, meaningless recording / playback processing will continue. In the case of using a battery as a power source, the battery runs out immediately. In addition, if it is a delay of several minutes, if it is more than that, if you are planning to continue watching other channel programs, you may not be able to miss the start time and miss some of them. It will also end up. Also, if you plan to go out after watching the current program until the end, if the chasing playback is greatly delayed, such as 20 minutes or 30 minutes, the scheduled time will be increased when you finish watching the program. It was too late and could cause problems such as being late.

An object of the first invention is to be able to guide the distinction between a chasing playback video and a real-time video currently being broadcast.
An object of the second invention is to be able to guide a time delay between a chasing playback video and a real-time video currently being broadcast.

  The guidance means displays the time difference on the condition that the time difference between the current chasing playback video and the received video during the recording operation is equal to or less than a predetermined value (the invention according to claim 10).

  According to the invention described in claim 1 (first invention), when the reproduction of the recorded content is instructed during the recording operation of the received content currently being broadcast, the recorded content is reproduced while continuing the recording operation. Since the chasing playback to be output is started and the chasing playback video is displayed during the chasing playback operation, the chasing playback video is displayed for the viewer. It is possible to know this, and quick response such as fast-forward playback is possible, and various inconveniences caused by continuing chasing playback can be effectively solved.

According to the second aspect of the invention, in addition to the same effect as the first aspect of the invention described above, the video displayed on the television screen is a received video currently being broadcast, or in a chasing playback operation. Therefore, it is possible to immediately distinguish the chasing playback video from the currently broadcast real-time video.
It should be noted that during chasing playback operation, an icon indicating chasing playback video may be displayed, and when displaying real-time video, the icon display may be deleted for identification display.

  According to the third aspect of the invention, in addition to having the same effect as that of the first aspect of the invention described above, is the video displayed on the television screen a playback video output during playback after the recording is completed? Since it is determined on the television screen whether the playback video is output during the chasing playback operation, it is possible to immediately distinguish the video being chased from the video after the completion of recording.

  According to the invention described in claim 4, in addition to 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 where the current broadcast content is received and output, After starting the operation to record the received content sequentially, when the playback operation of the recorded content is started in response to the instruction to cancel the interruption, the chasing playback video is displayed as a guidance display. Therefore, it is possible to inform that the video is a chasing playback video recorded as an emergency when the output is interrupted.

According to the invention described in claim 5, in addition to having the same effect as the invention described in claim 1 described above, the current recording position is compared with the reproduction position during the chasing reproduction operation, and the reproduction position becomes the recording position. When catching up, the guidance display indicating that the chasing playback video is being displayed is canceled, so that it is possible to notify the status of catching up with the real-time video currently being broadcast.
In this case, when it is determined that the playback position has caught up with the recording position, the recording operation is stopped, and the state in which the recorded content is reproduced and output is switched to the state in which the received video currently being broadcast is output (invoice (Invention of Item 6), meaningless recording can be prevented, wasteful power consumption can be suppressed, and a smooth transition to video output currently being broadcast can be made.

  According to the seventh aspect of the present invention (second invention), when the reproduction of the recorded content is instructed during the recording of the reception content currently being broadcast, the recorded content is reproduced and output while continuing the recording operation. The chasing playback is started, and the time difference between the current playback video during the chasing playback and the received video during the recording operation is obtained and displayed as a guide, so the chasing playback video and the real-time video currently being broadcast are displayed. You can know how much time it takes to catch up with real-time video, and how fast you need to fast-forward.

  According to the invention described in claim 8, in addition to having the same effect as that of the invention described in claim 7 described above, the current recording position and playback position can be obtained during chasing playback in which the recorded contents are reproduced and output while continuing the recording operation. Since a time difference is obtained from the position difference between the recording position and the reproduction position and is displayed for guidance, the time difference can be easily obtained from the position management.

  According to the invention described in claim 9, in addition to having the same effect as that of the invention described in claim 7, the broadcast contents for the capacity are sequentially written in the recording memory for temporarily storing the received broadcast contents, Since the latest broadcast contents corresponding to the capacity are recorded and held in the recording memory while sequentially updating the contents of the recording memory, it is not necessary to record all of one program, and recording in an endless format is possible. Therefore, a small capacity is sufficient for this recording memory.

  According to the invention described in claim 10, in addition to having the same effect as that of the invention described in claim 7, the time difference between the current chasing playback video and the received video during the recording operation is not more than a predetermined value. In addition, since the time difference is displayed as a guide, it is possible to know that the chasing playback video and the real-time video currently being broadcast are close in time by this guidance display, and instructing fast-forward playback if necessary. , You can instruct to jump to real-time video.

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.

When the television receiver 11 is in operation, the CPU 1 responds to the interruption instruction in response to the interruption instruction when the interruption of the output is instructed by the incoming call or the like in a state where the received broadcast contents are sequentially output (T1). The operation of sequentially recording the received contents thereafter is started. Thereafter, when an instruction to cancel interruption (interrupt end) is given by the end of a call or the like (T2), a chasing reproduction operation for reproducing and outputting recorded contents in parallel is started while continuing this recording operation. In this chasing playback, the recording operation is reproduced and output in parallel while continuing the recording operation, and the recording operation and the reproducing operation may be 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.

FIG. 4 is a diagram for explaining the temporary recording memory 4A used for chasing playback.
The temporary recording memory 4A is provided in the memory 4 and has a storage capacity capable of storing received broadcast contents for 10 minutes. The CPU 1 records the contents of the program currently being broadcast while updating the recording position indicating the current write address in the temporary recording memory 4A while recording the video position and the audio data while updating the reproduction position indicating the current read address. The recorded contents are read from the memory 4A and reproduced and output (video output and audio output). In this case, when the recording position / playback position reaches the end position of the temporary recording memory 4A, the CPU 1 executes the recording / playback operation in an endless format while returning the recording position / playback position to the top position of the temporary recording memory 4A. Like to do. 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.

FIG. 5 is a diagram showing a television screen (playback screen) during the chasing playback operation.
The CPU 1 performs a chasing playback operation in order to identify and display on the TV screen whether the video displayed on the TV screen is a received video (real-time video) currently being broadcast or a chasing playback operation. In the middle, a chasing icon RN indicating chasing playback is displayed and output. The chasing icon RN is a running image icon, but may be an animation of the running image. In addition, the CPU 1 detects the current recording position and the reproduction position, compares the recording position and the reproduction position, obtains a difference (position difference) between the recording position and the reproduction position, and based on the position difference, tracks the current chase. The time difference between the reproduced video and the received video (real-time image) currently being broadcast is obtained and displayed for guidance. That is, the time difference bar TB is a scale display of the time difference between the chasing playback video and the real-time image, and a specific time difference is numerically displayed below the time difference bar TB. In the illustrated example, the chasing playback video is delayed by “45 seconds” with respect to the real-time image.

  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.

6 and 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 in FIG. 6), the CPU 1 starts a receiving operation for receiving the contents of the broadcast program of the designated channel from the television receiver 11. At the same time (step S2), an output operation for sequentially outputting the received broadcast contents is started (step S3). In such “reception output mode”, 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.

  In such a state where the television program is being viewed, 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 S5). Thereafter, the process waits until there is an interrupt instruction or key operation.

  Now, when the presence of a key operation is detected in step S5 described above, for example, when a key operation such as a volume adjustment operation or a brightness adjustment operation is performed, a process corresponding to the operation key (for example, recording start) After performing the process such as volume adjustment (step S7), the process returns to the above-described step S5. However, when the mode switching key is operated to switch from the “reception output mode” to the “reproduction mode” (step S7). The TV broadcast reception operation is stopped (YES in S6) (step S8). Then, a list of recording files that have been generated and recorded and managed in the memory 4 or the like is displayed (step S9). In this case, a list of file names is displayed, and when a desired file is selected and designated from the list screen (step S10), the reproduction operation is started from the top position of the selected file (step S11). Now, since the playback is accompanied by switching from the “reception output mode” to the “playback mode”, an icon (not shown) indicating normal playback is guided and displayed on this playback screen (step S12).

  In this state, while checking whether or not a key is operated (step S13), it is checked whether the playback position has reached the end position of the recorded file (step S14). Now, if any key operation is performed, if it is not an end key for instructing the end of reproduction (NO in step S15), the process proceeds to a process corresponding to the operation key (step S19), but the reproduction end key is operated. (YES in step S15), the reproduction operation is stopped at this point (step S16). Then, the “reproduction mode” is canceled to return to the “reception output mode” (step S17), and after the icon display indicating the normal reproduction described above is deleted (step S18), the process returns to the above step S4 and the reproduction screen is displayed. Instead, it switches to the TV screen currently being broadcast. If the playback position has reached the end position of the recorded file (YES in step S14), the process returns to the recorded file list screen (step S9), and the above-described operation is repeated.

  On the other hand, when 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 S4), the CPU 1 temporarily receives the received contents thereafter. The recording operation of sequentially writing from the head position of the recording memory 4A is started (step S20), and the output of the received broadcast content is temporarily stopped, that is, the video display from the main display unit 9 and the built-in speaker 13 or earphone 14 Audio output is temporarily stopped (step S21).

  Then, after an interrupt screen (not shown) indicating that the output of the received content is in a suspended state is displayed and output instead of the television screen (step S22), this output interruption interrupt is released. (Step S23). 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 S23), the CPU 1 switches to the “reproduction mode”. (Step S24). In this “reproduction mode”, the reproduction operation is started from the head position of the recording memory 4A (step S25), and the chasing reproduction icon RN shown in FIG. 5 is guided and displayed (step S26).

  Next, the process proceeds to step S27 in FIG. 7, and the CPU 1 detects the recording position and the reproduction position, calculates the position difference between them, and based on the position difference, the current chasing reproduction video and the received video currently being broadcast. The time difference from the (real-time image) is obtained, and it is checked whether it is 20 seconds or less (step S28). On the condition that it is 20 seconds or less, the time difference bar TB shown in FIG. A specific time difference is displayed numerically on the side (step S29). In this state, the presence / absence of key operation is checked (step S30), or whether the chasing playback video has caught up with the real-time image currently being broadcast, that is, whether the position difference (time difference) is “0” (step S31). While checking whether the recording position has reached the end position of the temporary recording memory 4A (step S32), the process returns to the above step S27, and the above operation is repeated.

  Here, it is checked whether the fast forward playback key has been operated (step S33), the normal playback key has been operated (step S34), and the playback stop key has been operated (step S35). If the normal playback key is operated (YES in step S34), the playback operation at normal speed (substantially the same speed as the recording speed) is started (step S38), but when the fast-forward key is operated (step S38). For example, when the playback stop key is operated, the playback operation is stopped (step S39) and the other keys are operated. If so (NO in step S), processing corresponding to the operation key is performed (step S36).

  The CPU 1 detects the current recording position, and when the recording position reaches the end position of the temporary recording memory 4A during the chasing playback operation as shown in FIG. 4 (YES in step S32), the recording position is temporarily set. After returning to the head position of the recording memory 4A (step S33), the process returns to step S27 for calculating the difference between the reproduction position and the recording position. Even when the playback position reaches the end position of the temporary recording memory 4A, the playback position is returned to the head position of the temporary recording memory 4A. Further, when the difference (positional difference) between the chasing playback video and the real-time image becomes “0” and the chasing playback video catches up with the real-time image currently being broadcast (YES in step S31), the playback operation is performed at this time. Is stopped (step S40), and the “reproduction mode” is canceled (step S41). Then, after the chasing playback icon RN and the time difference bar TB are turned off (step S42), the process returns to the first step S1.

  As described above, in this embodiment, the CPU 1 continues this 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. The chasing playback icon RN indicating that the chasing playback video is being displayed during the chasing playback operation is displayed and displayed on the TV screen. Can be identified and displayed on the TV screen whether the received video is a received video that is currently being broadcast or a video that is being chased, and real-time video that is currently being broadcast and Can be immediately identified, and viewers can know that the video for follow-up playback is displayed, and fast-forward playback and other There correspondence is possible, it is possible to effectively eliminate various inconveniences due to cause continued endlessly chasing playback.

  Further, the CPU 1 responds to the output interruption interrupt instruction in a state where the current broadcast content is being received and output, starts an operation for sequentially recording the subsequent reception contents, and then responds to the interrupt release instruction. When the playback operation of the recorded content is started, the chasing playback icon RN is displayed as a guide, so that it can be notified that the video is a chasing playback video recorded as an emergency when the output is interrupted. .

  In addition, when the playback position catches up with the recording position by comparing the current recording position with the playback position during the chasing playback operation, the display of the chasing playback icon RN is deleted. You can be notified of the state of catching up with the video. In this case, when it is determined that the playback position has caught up with the recording position, the recording operation is stopped, and the state in which the recorded content is reproduced and output is switched to the state in which the received video currently being broadcast is output. In addition to being able to prevent meaningful recording, it is possible to reduce wasteful power consumption and to smoothly shift to the video output currently being broadcast.

  On the other hand, since the CPU 1 obtains a time difference between the current playback video and the received video (real-time video) during the recording operation during the chasing playback operation and displays it by the time difference bar TB, the video of the chasing playback and the current video are displayed. You can know the time delay from the real-time video being broadcast, and you can know how much time it takes to catch up with the real-time video and how fast you can fast-forward. In this case, since the time difference is obtained from the position difference between the recording position and the reproduction position and displayed for guidance, the time difference can be easily obtained from the position management.

  In addition, after the broadcast contents for the capacity are sequentially written in the temporary recording memory 4A, the latest broadcast contents for the capacity are recorded and held in the temporary recording memory 4A while the contents of the temporary recording memory 4A are sequentially updated. Therefore, it is not necessary to record all of one program, and recording in an endless format is possible, so that the temporary recording memory 4A needs a small capacity. Also, since the time difference bar TB is displayed as a guide on the condition that the time difference between the current chasing playback video and the received video during the recording operation is 60 seconds or less, the chasing playback video and the current broadcast are displayed by this guidance display. It is possible to know that it is close in time to the real-time video inside, and it is possible to instruct fast-forward playback or jump to the real-time video as necessary.

  In the above-described embodiment, the case where the icon of the running image is animated as the chasing playback icon RN is illustrated. However, the present invention is not limited to this. The shape of the RN is arbitrary. Further, the time difference bar TB has exemplified the scale format, but it may be a pie chart format, and the shape thereof is arbitrary.

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. May be switched automatically. 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 recording medium having a program code that can be read by a computer, and when the playback of the recorded content is instructed during the recording operation of the currently broadcasted received content, the recorded content is recorded while continuing the recording operation. To provide a chasing playback function for reproducing and outputting, a function for guiding and displaying that chasing playback video is displayed during the chasing playback operation, and a computer-readable recording medium recording a program for realizing the function It may be.

  In addition, when a recording medium having a computer-readable program code is instructed to reproduce the recorded content during the recording operation of the currently broadcasted received content, the recorded content is recorded while continuing the recording operation. A computer that records a program that implements the chasing playback function for playback output and the function to obtain and display the time difference between the current playback video and the received video during the recording operation during this chasing playback operation. A possible recording medium may be provided.
