Description

  The present invention relates to a mobile communication terminal, and more particularly to an improvement of a communication terminal such as a mobile phone that can receive TV broadcast waves and display a TV image on a screen.

  In recent years, mobile phones that can receive TV (TeleVision) broadcast waves and display TV images have become widespread. In such a mobile phone, a TV broadcast wave of a channel selected by the user is received, a TV image and TV sound are generated, and screen display and sound output are performed. Generally, the display screen of a mobile phone is not large enough to display a plurality of application screens simultaneously without reducing visibility. Therefore, in this type of mobile phone, it is necessary to switch the screen display when trying to newly display an application screen such as an e-mail viewing screen without lowering the visibility while displaying a TV image.

  Normally, when an application that uses the entire display screen is activated while a TV image is being displayed, the TV broadcast wave reception process is terminated, or the output of TV audio is stopped. For this reason, in the mobile phone described above, if another application is activated while a TV image is being displayed, the screen display is switched and the output of the TV sound is stopped, so that the broadcast content cannot be understood. It is convenient if the broadcast content can be recognized by TV sound even after switching from the TV image screen display to another screen display. For example, it is convenient if it is possible to recognize when a program ends or when a TVCM ends when switching to another application screen during a TVCM broadcast during a broadcast program or during a broadcast program or between programs.

Therefore, after the screen display is switched from the display of the TV image to the display of another application, the TV broadcast wave reception process and the TV sound output are continued so that the user can recognize the broadcast content by the TV sound. Conceivable. However, even after switching to another application, TV broadcast wave reception processing and TV audio output continue, so if the screen display by the other application is continued without returning to the original TV image screen display. There is a problem that power consumption increases. In addition, in order to stop the TV broadcast wave reception process during the screen display by the other application, the screen display must be switched to the TV image display.

In a state in which a call state is established with the other party's telephone, a voice signal based on the user's call sound is transmitted from the cellular communication unit 11 and a voice signal based on the call sound from the other party's telephone is received by the cellular communication unit 11. As a result, the call sound is transmitted and received in real time.

  The TV broadcast receiving unit 12 is a tuner that receives a TV broadcast wave transmitted from a TV station via a TV broadcast receiving antenna 12a. The TV broadcast receiving unit 12 generates reception data including TV images, TV sound, and attribute information. The TV broadcast wave transmitted from the TV station includes an analog broadcast wave corresponding to analog broadcast and a digital broadcast wave corresponding to digital broadcast. The digital broadcast wave received by the TV broadcast receiving unit 12 is a one-segment broadcast wave for a mobile phone assigned to a certain band of a general digital high-definition broadcast wave. In addition to the TV image and TV sound, the TV image Attribute information includes character information such as subtitles and related articles corresponding to, audio information such as the presence or absence of sub-speech, channel information corresponding to the frequency band of received radio waves, and the like.

  In the TV broadcast wave reception process by the TV broadcast receiver 12, a baseband signal included in a specific frequency band corresponding to the channel selected by the user is extracted and output as reception data.

  Based on the TV broadcast wave received by the TV broadcast receiver 12, a TV image is displayed on the display screen 2a, and a TV sound corresponding to the TV image is output from the speaker 14a to view the TV broadcast. Can do. Further, by extracting the character information included in the TV broadcast wave and displaying it on the display screen 2a, it is possible to display character information such as subtitles together with the TV image. Further, if TV images and TV sounds based on TV broadcast waves are stored in a memory (not shown), TV broadcasts can be recorded.

  The operation input unit 13 performs an operation of generating an input signal based on the operation of each operation key 4a. An LCD (Liquid Crystal Display) 17 is an image output device having a display screen 2a. The image generation unit 16 performs an operation of generating image data and causing the LCD 17 to display the screen. Specifically, a standby screen, an incoming screen, an e-mail browsing screen, a TV image, and the like are generated as image data.

  The standby screen is a screen that is displayed when waiting, and the incoming call screen is a screen that is displayed when an incoming call or e-mail is received. The email browsing screen is a screen for displaying header information and email text of received emails, or for creating and editing emails. In the image generation unit 16, a TV image is generated based on the reception data input from the TV broadcast reception unit 12 via the main control unit 15, and a reproduced image is displayed on the display screen 2a.

  The TV viewing control unit 18 controls the TV broadcast reception unit 12, the audio output unit 14, and the image generation unit 16 based on the input signal input from the operation input unit 13 via the main control unit 15, and displays the TV image on the screen. An operation for displaying and outputting TV sound is performed. The TV viewing control unit 18 performs control to interrupt the screen display of the TV image and switch to another screen display, or return to the screen display of the original TV image.

  FIG. 5 is a block diagram illustrating a configuration example of a main part of the mobile phone 1 of FIG. 4, in which a TV viewing control unit 18 is illustrated. The TV viewing control unit 18 includes a TV display interruption processing unit 21, a timer 22, a TV display restart processing unit 23, and a TV audio automatic stop unit 24. The TV display interruption processing unit 21 performs a process of interrupting the screen display of the TV image based on the input signal from the operation input unit 13 and switching to another screen display.

  Specifically, based on a user operation during the display of the TV image, an image generation interruption signal is generated as a control signal for interrupting the screen display of the TV image and switching to another screen display. Is output. For example, display of a TV image is interrupted based on key operations for switching to an e-mail viewing screen, an input screen for a schedule book, or an input screen for performing calculations using a calculator function. In other words, if an application that performs screen display using the entire TV image display area is activated while the TV image is being displayed, the TV image screen display is interrupted.

  Here, it is assumed that the reception processing by the TV broadcast receiving unit 12 and the TV audio output by the audio output unit 14 are continued after the screen display switching by the TV display interruption processing unit 21 and only the TV image display is interrupted.

  The timer 22 is a time measuring unit that starts a time measuring operation based on switching of screen display by the TV display interruption processing unit 21. The timer 22 is timed up when a predetermined time has elapsed from the start of timing, and performs an operation of outputting a control signal indicating the time up.

  The TV display restart processing unit 23 performs a process of restarting the screen display of the TV image based on the input signal from the operation input unit 13 during the time measurement of the timer 22 and ending the time measurement. That is, if a key operation for returning to the original TV image is performed between the time when the TV image is interrupted and the timer 22 time-up, the screen display of the TV image is resumed based on this key operation. An image generation resumption signal is generated as a control signal for output to the image generation unit 16. In the image generation unit 16, the screen display is switched to the screen display of the TV image based on the image generation restart signal, and a reproduced image is displayed. Further, a control signal for ending the timing operation based on the key operation is generated and output to the timer 22.

  The TV sound automatic stop unit 24 performs an operation of stopping the output of the TV sound based on the time-up of the timer 22. That is, a sound output stop signal is generated as a control signal for stopping the output of TV sound based on the control signal from the timer 22 and is output to the sound output unit 14.

  By continuing the output of the TV sound, it is possible to continue to listen to the TV sound even if the screen display of the TV image is interrupted and switched to another screen display. The user can be recognized by voice. For example, it is possible to recognize the switching of broadcast programs and the end of TVCM. Further, by stopping the output of the TV sound based on the time-up of the timer 22, the TV sound output is automatically stopped when another screen display is continued without returning to the original TV image. Therefore, an increase in power consumption can be suppressed.

  Here, it is assumed that the reception process by the TV broadcast receiving unit 12 is continued even after the TV sound output stop by the TV sound automatic stopping unit 24 is stopped. In other words, while the screen display of the TV image is interrupted, the TV broadcast wave reception process and TV sound output are performed until the timer 22 times out. When the timer 22 times up, the TV broadcast wave reception is performed. It shifts to a so-called standby mode in which only processing is continued. In this way, by continuing the TV broadcast wave reception process even after the TV image display is interrupted, if the key operation for returning to the original TV image is performed, the screen display of the TV image is promptly resumed. Can do.

  Here, it is also assumed that the TV is turned on and off by operating a predetermined operation key 4a. When the TV is turned on, a TV broadcast wave reception process is started, a TV image is displayed on the screen, and a TV sound is output. On the other hand, if the TV is turned off, the TV broadcast wave reception process is stopped and the TV is terminated. Further, it is assumed that a screen display such as an e-mail browsing screen and a TV image screen display can be switched by operating the operation key 4a while the TV image display is interrupted.

  Here, when a TV call is received while viewing the TV in the vertically long state of the display screen 2a, the screen display of the TV image and the output of the TV sound are interrupted and the standby mode is set. On the other hand, if there is an incoming call while watching TV in the landscape state, only the output of TV sound is stopped and the screen display of the TV image is continued.

  Note that the TV broadcast wave reception process may be stopped when the TV sound automatic stop unit 24 stops the TV sound output, and the TV may be terminated.

  FIG. 6 is a transition diagram showing an example of the operation in the mobile phone 1 of FIG. 4, and shows the display screen 2a when the TV image display is interrupted. In this example, a case where a TV image is displayed on the screen when the display screen 2a is in the landscape state is shown. In this horizontally long state, the display area is expanded in the left-right direction compared to the up-down direction as viewed from the user. In such a horizontally long state, a pictogram (pictogram) display area 31 is provided at the upper end of the display screen 2a, and an icon display area 33 is provided at the lower end. A TV image display area 32 is provided between the display area 31 and the display area 33.

  In the display area 31, there are arranged pictograms indicating the reception intensity of radio waves, incoming e-mails, and the remaining battery level. In the display area 33, a menu icon 33a and an end icon 33b are arranged. The menu icon 33a is an icon associated with a predetermined operation key 4a (menu key), and the end icon 33b is an icon associated with another operation key 4a (end key). The menu key is an operation key for displaying a menu screen. The end key is an operation key for ending the running application.

  While the TV image is being displayed, the TV sound output is turned on, and the TV sound corresponding to the TV image is reproduced from the speaker 14a. In this state, when a user operation for interrupting the display of the TV image and switching to another screen display (in this case, the display of the received mail browsing screen) is performed, the output of the TV sound remains on and the TV image remains on. Is interrupted and the received mail browsing screen is displayed. When the timer 22 expires after a lapse of a predetermined time after the TV image display is interrupted, the TV sound output is turned off and the standby mode is entered.

  Steps S101 to S108 in FIG. 7 are flowcharts showing an example of the operation in the mobile phone 1 in FIG. First, when a TV image interruption operation is performed during TV viewing, the TV display interruption processing unit 21 interrupts the TV image screen display based on the interruption operation and switches the screen display (steps S101 and S102). When the screen display is switched from the TV image to another screen, the time counting operation by the timer 22 is started.

  Next, if a TV image restart operation is performed before the timer 22 times out, the TV display restart processing unit 23 restarts the screen display of the TV image based on the restart operation (steps S103 to S105). The timing operation of the timer 22 is terminated (step S106). On the other hand, if the timer 22 times out, the TV sound automatic stop unit 24 stops the output of TV sound based on this time up (steps S107 and S108).

  According to the present embodiment, it is possible to continue listening to TV sound even if the screen display of the TV image is interrupted and switched to another screen display. In addition, if the timer 22 times out without restarting the screen display of the TV image, the output of the TV sound is stopped. Therefore, other screen display is continued without returning to the screen display of the original TV image. In this case, the output of TV sound can be automatically stopped. Therefore, another screen display can be continued without increasing the power consumption and without returning to the original TV image screen display. Since the TV broadcast wave reception process is continued even after the TV sound output is stopped, the TV image can be promptly displayed on the screen when the user restarts the screen display of the TV image as necessary.

Embodiment 2. FIG.
In the first embodiment, an example in which the time measurement is started when the screen display is switched by the TV display interruption processing unit 21 has been described. In contrast, in the present embodiment, a case will be described in which time measurement is started based on a change in attribute information extracted from received data.

  FIG. 8 is a block diagram illustrating a configuration example of a main part of the mobile phone according to the second embodiment of the present invention, in which a TV viewing control unit 101 including an attribute information extraction unit 102 is illustrated. The attribute information extraction unit 102 performs an operation of extracting attribute information from the reception data from the TV broadcast reception unit 12. The attribute information included in the reception data of the TV broadcast wave includes character information such as subtitles associated with the TV image, sound information such as the presence / absence of sub-audio and stereo broadcast, and channel information corresponding to the frequency band of the received radio wave The program information associated with the broadcast program is used for TV viewing.

  In the present embodiment, the timer 22 starts timing based on the change in the attribute information after the screen display switching processing unit 21 switches the screen display. That is, if the attribute information changes after the TV image display is interrupted, the timer 22 starts the time measuring operation. Normally, the attribute information changes when the broadcast program ends, switches to another broadcast program, or TVCM ends. By detecting such a change in attribute information and starting timing when the attribute information changes, it is possible to appropriately stop the output of TV sound. For example, it is possible to prevent TV sound from being continuously output even though the broadcast program is switched after the TV image is interrupted.

In addition, the TV viewing reservation processing unit 124 compares the current time with the start time and the end time, and performs an operation of displaying a TV image on the screen based on the comparison result. Specifically, a TV viewing control signal is output to the TV broadcast receiving unit 12, the image generating unit 16, and the audio output unit 14 based on the viewing reservation information, and a TV image is displayed and TV audio is output.

  In the present embodiment, the TV sound automatic stop unit 24 stops the output of TV sound based on the recording state by the TV recording processing unit 122 and the viewing reservation by the TV viewing reservation processing unit 124. For example, during the recording of a TV broadcast or the viewing of a TV broadcast reserved for viewing, the TV sound is not automatically stopped, and the TV sound is not recorded when the TV broadcast is not recorded or when the reserved TV broadcast is not viewed. Is automatically stopped. According to such a configuration, automatic stop of TV sound can be appropriately performed.

  Note that reservation recording of TV images may be controlled according to the connection state of the display housing 2 and the operation housing 4, the reception state of TV broadcast waves, and the remaining memory capacity that can be recorded. Specifically, when the recording of TV images is automatically started based on time information designated in advance by the user and both the housings are folded, the reception state of the TV broadcast wave is deteriorated. It is conceivable that the recording process is stopped and the timer 22 starts timing. At that time, if the reception state recovers until the timer 22 times out, the recording process is resumed. On the other hand, if the timer 22 times out without recovering the reception state, the TV broadcast wave reception process is stopped. Then, the scheduled recording ends.

  Alternatively, when the recording of the TV image is automatically started based on the time information designated in advance by the user and both the housings are in the folded state, the remaining memory capacity that can be recorded in the recording data storage unit 123 It is conceivable to cause the timer 22 to start measuring when the time becomes less. At that time, if the recording process does not end before the timer 22 expires, the TV broadcast wave reception process is stopped when the timer 22 expires, and the reserved recording ends.
