The TV broadcast receiving unit 11 receives a terrestrial digital broadcast transmitted from a TV station through a transmission base station. The high-resolution digital TV broadcast (12-segment broadcast) and the low-resolution digital TV broadcast (1-segment broadcast) ) And can be received. Note that digital broadcasts can be downloaded and received via a wireless communication network such as Internet radio or the Internet. The TV broadcast receiving unit 11 can receive not only TV video and audio information but also an electronic program guide (EPG) and the like, and is connected to a TV antenna and extracts a broadcast signal (analog circuit). Part) and the received broadcast signal is demodulated by OFDM (Orthogonal Frequency Division Multiplexing), separated from the multiplexed broadcast signal into video, audio, and data (character data), or decompressed compressed data, etc. A digital circuit unit for performing

The TV video data and character data received by the TV broadcast receiving unit 11 are displayed and output from the display unit 9, and the TV audio data is output from the sound speaker 12 as audio. The CPU 1 switches from the 12-segment reception mode to the 1-segment reception mode and records the television broadcast received in the 1-segment reception mode when instructed to temporarily suspend during viewing in the 12-segment reception mode. When the operation is started and then the end of the temporary interruption is instructed, a reproduction operation for reproducing the recorded content recorded in the 1-segment reception mode is started.

In this case, chasing playback (fast-forward playback) in which the recorded contents are sequentially reproduced and output from the beginning is performed while continuing the recording operation. Here, the temporary interruption instruction is given when the interruption / end key 8d is operated during the reception output of the television broadcast or when an incoming call is detected. The recording operation that is started when the interrupt / end key 8d is operated or the incoming call is detected during the TV broadcast reception output is hereinafter referred to as “temporary recording”.

FIG. 2 is a diagram for explaining the operation contents after that when a temporary interruption is instructed during the reception and output of 12-segment broadcasting, and FIG. The situation, (b) shows the recording situation, and (c) shows the viewing situation.
The illustrated example shows a case where the temporary interruption is instructed when the 12-segment broadcast is viewed for 5 minutes, and the interruption state continues for 5 minutes. In this case, in response to the interruption instruction during the reception output of the 12-segment broadcast, the CPU 1 switches from the 12-segment reception mode to the 1-segment reception mode, as well as recording for temporarily recording the television broadcast received in the 1-segment reception mode. The operation starts.

Then, after this interrupted state continues for 5 minutes, when the end of the interrupt is instructed, chasing playback is started in which the recorded contents are sequentially reproduced and output from the beginning while continuing the recording operation. In this case, if the chasing playback is 1.5 times fast-forward playback, after 15 minutes have elapsed from the start of the temporary recording, that is, after starting the chasing playback that fast-forwards the recorded content of the 1-segment broadcast. Since all the recorded contents have been output (viewed) when 10 minutes have passed, the chasing playback is terminated at this point and the original 12-segment broadcast is switched from the 1-segment reception mode to the 12-segment reception mode. Is ready for viewing.

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. That is, in addition to the recording medium, an operation specific to this embodiment can be executed using a program / data supplied externally via a transmission medium. 3 and 4 are flowcharts showing an outline of the operation of the characteristic part of the present embodiment in the entire operation of the mobile phone device. When the flow of FIG. 3 and FIG. Return to the main flow of operation (not shown).

FIG. 3 is a flowchart that starts execution when the TV broadcast receiving unit 11 is instructed to be activated by the TV on / off key 8c.
First, when the television broadcast receiving unit 11 is activated, the CPU 1 performs a process of selecting the reception mode set at the end of the previous television function as the current reception mode (step A1). That is, when the first reception mode (12-segment reception mode) has been set at the end of the previous television function, this 12-segment reception mode is selected and the second reception mode (1-segment reception mode) is set. If so, this 1-segment reception mode is selected. The channel is designated in this selective reception mode. In this case, the channel set at the end of the previous television function is designated as the current channel.

After such initialization processing (steps A1 and A2) is completed, a broadcast program of a designated channel is received from the television broadcast receiver 11, and a reception output operation for outputting the video data and audio data is started (step A3). ), The operation waits while continuing the reception output (step A4). Now, if any operation is performed (YES in step A4), is it an operation to change the channel (step A5), an operation to change the reception mode (step A6), or during the reception output of the television broadcast? It is checked whether the operation is an operation for instructing the interruption (step A7) or an operation for instructing the end of driving of the television function (step A8).

If a channel change operation is performed (YES in step A5), the process returns to step A3 described above to receive and output a broadcast program of a newly designated channel. When a reception mode changing operation is performed (YES in step A6), the process returns to step A2 described above, and channel designation is performed in the newly selected reception mode. Further, when the interruption / end key 8d is operated during the reception and output of the television broadcast and the interruption is instructed (YES in step A7), the process proceeds to step A10 described later. When the TV on / off key 8c is operated to instruct the end of the TV (YES in step A8), the flow of FIG. 3 ends. When another operation is performed (NO in step A8), for example, after performing a volume change process or the like as a process corresponding to the operation (step A9), the process returns to the above-described step A4 and enters the operation waiting state. Become.

Further, in response to the temporary interruption instruction operation (YES in step A7), a confirmation message asking whether or not to record 1-segment broadcasting (temporary recording) is displayed (step A10). Here, when a response operation for refusing the temporary recording of the 1-segment broadcasting is performed (NO in step A11), after executing the output OFF process for stopping the output of the television broadcasting (step A27), the above-described interruption termination is performed. The process waits until instructed (step A28). Now, when the interruption / end key 8d is operated to instruct the end of interruption (YES in step A28), an output ON process for restarting the output of the television broadcast is performed. After the execution (step A25), the process returns to the above-described step A4 and enters an operation waiting state.

On the other hand, when a confirmation message asking whether or not temporary recording of 1 segment broadcasting is necessary is displayed (step A10), when a response operation is performed to affirm temporary recording of 1 segment broadcasting (YES in step A11). It is checked whether the current reception mode is the 12-segment reception mode (step A12). If the current reception mode is the 12-segment reception mode, that is, if a pause is instructed during the reception and output of the television broadcast in the 12-segment reception mode (YES in step A12), the presence / absence of simultaneous broadcast is determined. In order to check, it is checked whether the same program is included in the same channel in the 1-segment broadcast, in other words, whether the program of the channel viewed in the 12-segment broadcast is currently being broadcast in the 1-segment broadcast (step A13). ).

Here, if there is no simulcast in 1-segment broadcasting (NO in step A13), a message indicating that recording is impossible is displayed (step A26). Then, similarly to the above case, after executing the output OFF process for stopping the output of 12-segment broadcasting (step A27), the process waits until the above-mentioned interruption end is instructed (step A28). If 1-segment broadcasting includes simultaneous broadcasting (YES in step A13), the 12-segment reception mode is switched to the 1-segment reception mode (step A14), and an output OFF process for stopping the output of the television broadcast is executed (step A14). Step A15).

Then, a 12-segment flag (not shown) is set to indicate that the 12-segment reception mode has been switched to the 1-segment reception mode (step A16), and temporary recording of the 1-segment broadcast received in the 1-segment reception mode is started. Then, the received contents are written into the recording memory RD (step A17). On the other hand, if the current reception mode is the 1-segment reception mode (NO in step A12), the process proceeds to step A17 as it is, and temporary recording of the 1-segment broadcast received in the 1-segment reception mode is started.

After recording is started in this manner, the process waits until the interruption / end key 8d is operated again to instruct the end of interruption (step A18). Now, when the end of interruption is instructed, follow-up reproduction is started to sequentially reproduce and output the contents of the recording memory RD from the beginning (step A19). During this chasing playback, the CPU 1 compares the current playback position with the recording position, monitors whether the playback position has caught up with the recording position (step A20), and continues the recording operation until the playback position catches up with the recording position. The playback operation continues.

If the playback position catches up with the recording position during chasing playback (YES in step A20), the end of the recording operation is instructed at this point (step B21), and the recorded content is deleted (step B22). Then, it is checked whether or not the 12-segment flag is set (step A23). If this flag is not set, the output of 1-segment broadcasting is resumed because the output of 1-segment broadcasting is interrupted. Although the process is executed (step A25), if the 12-segment flag is set (YES in step A23), after switching from the 1-segment reception mode to the original 12-segment reception mode (step A24), the output of 12-segment broadcasting The output ON process is restarted (step A25). Thereafter, the process returns to the above-described step A3 and enters an operation waiting state.

FIG. 4 is a flowchart that is started in response to an incoming call interruption.
First, when receiving an incoming signal from the telephone communication unit 6, the CPU 1 drives the notification unit 10 to perform incoming notification (step B1). Here, it is checked whether or not the TV is operating (the TV broadcast receiving unit 11 is being driven) (step B2), or whether or not the off-hook button 8a is operated (step B13). If NO in step B2) and the off-hook button 8a is not operated (NO in step B13), the flow in FIG. 4 ends at this point.

Further, when the off-hook button 8a is operated (YES in step B13), a call process for making a call ready state is executed (step B14), and then the on-hook button 8b is waited for operation (step B15). Here, when the on-hook button 8b is operated, the line is disconnected (step B16), and then it is checked whether the recording is started (temporary recording) in response to the above-described temporary interruption instruction (step B17). If the television is not operating, it is not temporarily recording (NO in step B17), and the flow in FIG. 4 is terminated at this point.

On the other hand, if the television is in operation at the time of incoming call (YES in step B2), a message to interrupt the output of the television broadcast is displayed in response to the incoming call (step B3). Then, whether or not the off-hook button 8a is operated is checked (step B4). If the off-hook button 8a is not operated, the flow of FIG. 4 ends at this point, but when the off-hook button 8a is operated (YES in step B4). ) After executing the output OFF processing for stopping the output of the television broadcast (step B5), it is checked whether the recording is already being executed (separately recording) (step B6). That is, “separately recording” means that recording other than the above-described temporary recording is being performed, and it is checked whether the program recording currently being viewed or the recording of a program other than viewing (back program) is being performed. If the video is currently being recorded separately (YES in step B6), the process proceeds to step B14 described above, and the call process is executed. If not separately recorded (NO in step B6), the current reception mode is 12 segments. It is checked whether the mode is the reception mode (step B7).

If the current reception mode is the 12-segment reception mode, that is, if an incoming call is detected during TV broadcast reception output in the 12-segment reception mode (YES in step B7), the remaining recording memory RD is used. It is detected and it is checked whether or not this remaining remaining capacity exceeds a predetermined capacity (step B8). Here, if the remaining free space is equal to or less than the predetermined capacity (NO in step B8), the 12-segment reception mode is switched to the 1-segment reception mode (step B10), and the 12-segment reception mode is switched to the 1-segment reception mode. After the 12-segment flag (not shown) is set (step B11), temporary recording of 1-segment broadcasting is started (step B12).

Also, if the remaining capacity of the recording memory RD exceeds the predetermined capacity and there is sufficient remaining capacity to record the 12-segment broadcast (YES in step B8), the remaining battery level of the power supply unit 2 is detected. Then, it is checked whether the remaining battery capacity exceeds a predetermined capacity (step B9). Here, if the remaining amount is equal to or less than the predetermined capacity, the 12-segment reception mode is switched to the 1-segment reception mode (step B10), and after the 12-segment flag is set (step B11), temporary recording of 1-segment broadcasting is started. (Step B12). Further, if the remaining battery capacity exceeds a predetermined capacity and there is a sufficient battery level to record 12-segment broadcasting (YES in step B9), temporary recording of 12-segment broadcasting is started (step B12). On the other hand, if the current reception mode is the 1-segment reception mode (NO in step B7), the process proceeds to step B12 as it is, and temporary recording of 1-segment broadcasting is started.

After starting the temporary recording in this way (step B12), the process proceeds to the next step B14 to perform a call process. Here, when the on-hook button 8a is operated (YES in step B15), the line is disconnected (step B16), and it is checked whether or not temporary recording is being performed according to the temporary interruption instruction (step B17). If the recording is not in progress (including the case of separate recording), the flow in FIG. 4 ends at this point. Further, if the temporary recording is in progress (YES in step B17), a confirmation message asking whether to confirm the temporarily recorded content by reproducing and displaying is displayed (step B18). Then, it is checked whether chasing playback is instructed in order to confirm playback of the recorded contents (step B19).

Now, when chasing playback is instructed (YES in step B19), the operation of chasing playback of the recorded content at 1.5 times speed is started while continuing the temporary recording (step B19). During this chasing playback, the CPU 1 compares the current playback position with the recording position, monitors whether the playback position has caught up with the recording position (step B22), and continues the chasing playback until it catches up. If the playback position catches up with the recording position (YES in step B22), the end of the recording operation is instructed at this point (step B23), and the recorded content is deleted (step B24). Then, it is checked whether the 12-segment flag is set (step B25). If it is set, after switching from the 1-segment reception mode to the original 12-segment reception mode (step B26), the output of the 12-segment broadcast is resumed. Although the output ON process is executed (step B27), if the 12-segment flag is not set (NO in step B25), the output ON process for restarting the output of 1-segment broadcasting is executed (step B27).

If no chasing playback is instructed (NO in step B19), the end of the recording operation is instructed to end the temporary recording (step B20). If the 12-segment flag is set (YES in step B25), after switching from the 1-segment reception mode to the original 12-segment reception mode (step B26), an output ON process for restarting the output of 12-segment broadcasting is executed. (Step B27). If the 12-segment flag is not set (NO in step B25), an output ON process for resuming the output of 1-segment broadcasting is executed (step B27). If the reproduction is not instructed in this way, the temporary recording is ended, and then the broadcast output is started while the recorded content is stored for later viewing.

As described above, in this embodiment, when the CPU 1 is instructed to suspend viewing during a television broadcast reception output in the 12-segment reception mode for receiving a high-resolution digital television broadcast, Since switching to the 1-segment reception mode for receiving television broadcasts and recording of the television broadcasts received in this 1-segment reception mode is started, it is effective in situations such as the current remaining memory capacity and remaining battery power. In addition to being able to record, users can watch the contents of the suspended broadcast later, even if it is necessary to temporarily suspend the viewing while watching TV with high resolution. Can do.

The reception mode is switched to the 1-segment reception mode on the condition that the reception mode when the suspension is instructed during the reception output of the television broadcast is the 12-segment reception mode. Can be switched.

Prior to switching to the 1-segment reception mode, since the same program as the program received in the 12-segment reception mode can be received in the 1-segment reception mode, it is switched to the 1-segment reception mode. Even if the reception mode is switched, the same program can be watched continuously.

Prior to switching to the 1-segment reception mode, switching to the 1-segment reception mode is performed on the condition that recording is not already being performed (separate recording is not being performed), so that it is possible to prevent influence on recording that is already being performed. .

Prior to switching to the 1-segment reception mode, the recording memory RD is switched to the 1-segment reception mode on condition that the remaining capacity of the recording memory RD is equal to or less than a predetermined capacity. Can be suppressed. For example, the used capacity (MB) of the recording memory RD required for recording 12-segment broadcasting for 5 minutes is 20 Mbps ÷ 8 × 60 seconds × 5 minutes = approximately when the encoding rate of 12-segment broadcasting is 20 Mbps. In contrast to 750 MB, the used capacity (MB) of the recording memory RD required to record 1 segment broadcast for 5 minutes is 256 bps ÷ 8 × 60, assuming that the encoding rate of 1 segment broadcast is 256 kbps. Seconds × 5 minutes = about 9.6 MB, and the capacity used for recording 1-segment broadcasting can be greatly reduced.

Prior to switching to the 1-segment reception mode, the switch to the 1-segment reception mode is made on condition that the remaining power of the power supply battery is equal to or less than the predetermined capacity. Can do.

Since it is determined whether or not a temporary interruption has been instructed based on whether or not an incoming call has been detected during the reception and output of a television broadcast in the 12-segment reception mode. The reception output of 12-segment broadcasting can be interrupted and 1-segment broadcasting can be recorded.

Since the reproduction of the recorded content recorded in the 1-segment reception mode is started when the end of the temporary suspension is instructed, the content broadcast during the suspension can be viewed immediately after the suspension is canceled.

Since the recording in the 1-segment reception mode is ended and the 12-segment reception mode is switched when the reproduction of the recorded contents is completed, it is possible to view a high-quality broadcast immediately after the end of the reproduction.

When the end of the temporary interruption is instructed, the recording in the 1-segment reception mode is ended and the mode is switched to the 12-segment reception mode, so that the current broadcast content can be viewed immediately after the cancellation of the interruption. You can watch the recording that was interrupted later.

In the above-described embodiment, the temporary interruption instruction is given when the interruption / end key 8d is operated during the reception of a television broadcast or when a telephone call is detected. When the amount of memory remaining below the specified capacity is insufficient, or when the remaining power level of the power supply battery is insufficient below the specified capacity, a temporary interruption instruction may be given. After recording temporarily after switching from 12-segment reception mode to 1-segment reception mode due to insufficient capacity, memory shortage is resolved by deleting existing recording contents or adding new memory, etc., or connected to a charger When the battery shortage is resolved, the 1-segment reception mode may be switched to the 12-segment reception mode.

In the above-described embodiment, the playback is performed at 1.5 times as the chasing playback. However, the fast-forward speed is arbitrary, and the playback is not limited to the chasing playback. It may be.
In addition, not only a mobile phone device having a digital broadcast receiving function, but also a personal computer / PDA (personal personal digital assistant) having a digital broadcast receiving function, or a digital television device itself may be used.

The block diagram which showed the basic component of the mobile telephone apparatus provided with the digital broadcast receiving function applied as a digital broadcast receiving apparatus. When a temporary interruption is instructed during reception and output of 12-segment broadcasting, the operation content after that is described in a time-series manner.
