Description

  The present invention relates to a digital broadcast receiving apparatus.

The present invention relates to a communication device.

  Even if the manner mode is set, as long as the mobile phone is turned on, the mobile phone automatically emits radio waves for location registration even if the user does not make or receive calls. However, when a call is received, no sound is emitted, but the response radio wave is automatically emitted. A radio wave is also transmitted when a data broadcasting is received by a portable telephone device having a digital broadcasting receiving function and a link operation is performed on the data broadcasting reception screen. In addition, in a digital broadcast receiving apparatus compatible with data broadcasting, regardless of whether it is configured as a portable type or a stationary type, unnecessary communication is performed when a child performs an operation on the data broadcasting reception screen. Will be executed.

  In view of the above circumstances, an object of the present invention is to provide a digital broadcast receiver capable of avoiding as much as possible unnecessary transmission of radio waves due to an operation on a data broadcast reception screen.

In view of the above circumstances, the communication device of the present invention prohibits communication by a receiving unit that receives a data broadcast and link connection that acquires information on a network based on link information on an image based on the data broadcast. A setting unit for setting whether or not, a determination unit for determining whether or not communication by link connection based on link information on the received data broadcast image is performed, and when communication by link connection is made, When prohibition of communication by link connection is set by the setting of the setting unit, a prohibition unit for prohibiting communication by link connection is provided.

  When the prohibit mode is set, the communication disconnection process may be executed when the link connection state is on the data broadcast reception screen. Further, it may be configured as a portable telephone device having a wireless telephone function, and further, it is determined whether it is in the vehicle by receiving a radio signal emitted in the vehicle and being in the vehicle. It may be configured such that the prohibit mode is enabled when the determination is made. Further, the wireless telephone function stop mode may be set at the same time that the prohibit mode is enabled when it is determined that the vehicle is in the vehicle.

  As described above, according to the present invention, it is possible to avoid as much as possible unnecessary transmission of radio waves due to an operation on a data broadcast reception screen.

  Hereinafter, an embodiment of the present invention will be described with reference to FIGS.

  FIG. 1 is a block diagram showing a portable telephone apparatus with a digital broadcast receiving function of this embodiment. The portable telephone device 2 uses the encoded video / audio data obtained by broadcast reception by the terrestrial digital tuner 230 or the encoded video / audio data read from the memory card 3 or the like inserted into the slot 201 to generate a video. Is displayed on the liquid crystal display panel 202, and sound is output from the earphone 203 (or speaker). In this embodiment, it is assumed that the encoded video data is MPEG4 data and the audio data is (MPEG2-AAC).

  MPEG4 data read from the memory card 3 is supplied to the MPEG4 video decoder 204 via the PCMCIA interface 220 and the system bus 213. Further, the tuner 230 that receives the terrestrial digital broadcast takes out the MPEG4 bit stream data broadcast by the terrestrial digital broadcast and supplies it to the MPEG4 video decoder 204 and the audio decoder (MPEG2-AAC) 206.

  The MPEG4 video decoder 204 obtains quantization coefficients and motion vectors by decoding the MPEG4 bitstream data, and performs video compensation obtained by performing inverse DCT conversion, motion compensation control based on the motion vectors, etc. to the graphics controller 205. Supply.

  The graphics controller 205 performs processing such as color adjustment on video data (for example, R, G, B data). The graphics controller 205 also performs OSD (on-screen display) processing for displaying on the liquid crystal display panel 202 characters or the like (operation button display, menu screen, etc.) output from the CPU 209. In addition, the graphics controller 205 can perform processing (scaling processing) to reduce the screen size of the broadcast received video, and the size can be changed so that the data broadcast portion and the message are displayed in the extra screen due to the screen size change. A screen (moving image plane) and a still image plane are generated. In addition, the graphics controller 205 can perform a process of displaying a window on the broadcast received video and displaying a message in the window. The CPU 209 functions as a BML browser when receiving a data broadcast, and gives a screen configuration instruction to the graphics controller 205. The audio decoder 206 decodes the audio code data in the bit stream to generate audio data. The SDRAM 210 is used in the above processing of the MPEG4 video decoder 204.

  The LCD controller 207 drives the liquid crystal display panel 202 based on the video data supplied from the graphics controller 205. The D / A converter 208 receives the audio data output from the audio decoder 206 and performs D / A conversion to generate a right (R) sound analog signal and a left (L) sound analog signal. This is given to the earphone 203.

  The main body key 214 includes operation buttons (TV viewing, recording, playback, pause, stop, feed) related to viewing, a numeric keypad, and the like. Operation information for the main body key 214 is given to the CPU 209 via the interface 215 and the system bus 213. The CPU 209 executes necessary processing based on the operation information.

  A flash ROM 218 and an SDRAM 219 are also provided. The battery 221 is a secondary battery, and obtains power from a charger (not shown) and stores it. The mobile phone unit 231 executes mobile phone processing (call, e-mail, web processing, etc.), which is the original function of the mobile phone device.

  The base station ID determination unit 231a of the mobile phone unit 231 detects the base station ID transmitted by the base station as a mobile phone control signal having a mobile phone frequency (for example, Japanese Patent Laid-Open No. 11-4236 for the base station ID). (See publications). Here, as shown in FIG. 2, for example, an in-vehicle notification device 11 is provided on the ceiling of the train 1. The vehicle in-vehicle notification device 11 transmits a base station ID indicating that the vehicle is in the vehicle, in the same manner as the base station transmits a base station ID as a mobile phone control signal having a mobile phone frequency. The mobile phone unit 231 determines whether the mobile phone device 2 is present in the vehicle based on the received base station ID, and notifies the CPU 209 of the presence in the vehicle when it is determined that the mobile phone device 2 is in the vehicle. When the CPU 209 is notified of the presence in the vehicle, the CPU 209 sets the stop mode of the mobile phone function.

  Even in the stop mode, the process of receiving the mobile phone control signal and determining the base station ID is continuously performed, but the radio wave amplification is reduced as compared with the normal radio wave amplification. Here, the radio wave amplification degree refers to the reception radio wave amplification degree and / or the transmission radio wave amplification degree. For example, if a power amplifier that performs radio wave amplification is controlled by an auto power controller, the auto power controller may be stopped to set the minimum amplification degree to the power amplifier. The time when the radio wave amplification level is lowered is called the weak mode, and the normal time is called the incoming mode. In addition, both modes are referred to as an antenna mode. The transmission wave level of the in-vehicle notification device 11 has a predetermined level so that the incoming call by the radio wave from the base station outside the vehicle is impossible in the weak mode, and the radio wave from the in-vehicle notification device 11 can be received. It is assumed that it is set to.

  Hereinafter, processing related to the suspension of the mobile phone function will be described in detail with reference to the flowcharts of FIGS.

  Telephone stop mode setting: When the user gets on the train with the telephone power turned on, the mobile phone unit 231 receives the base station ID issued from the in-vehicle informing device 11 and determines that the vehicle is in the vehicle. (Step S1). When notified of the presence in the vehicle, the CPU 209 displays on the LCD panel 202 that the mobile phone function stop mode is set (step S2). Next, the CPU 209 checks the antenna mode (step S3). If the antenna mode is the weak mode, the process proceeds to step S11. On the other hand, if the antenna mode is the incoming mode, it is determined whether a call is in progress (step S4). If it is waiting for reception (NO in step S4), the process proceeds to step S7. When the call is in progress (YES in step S4), a warning sound that informs the user that the call is to be disconnected is output from the speaker for a predetermined time (for example, 3 seconds) (step S5). Thereafter, the call is disconnected (step S6), and the antenna mode is set to the weak mode (step S7). The call stop mode is set by setting the weak mode. That is, since it is difficult to receive radio waves from the base station outside the vehicle by the weak mode, the incoming operation (ringer ringing) is not executed, and if the amplification of the transmitted radio wave is also reduced by the weak mode, the location registration In addition, the radio wave transmitted by the mobile phone itself is weak, and the influence on the heart pacemaker and the like is reduced. Since it is a process for reducing the radio wave amplification, there is no need to change the mobile phone outgoing / incoming protocol (for example, refer to Japanese Patent Laid-Open No. 10-42354 (IPC: H04Q7 / 36)), and the mobile phone 2 itself In other words, the same processing as the processing with the normal base station is performed with the in-vehicle notification device 11.

  The cellular phone unit 231 checks the base station ID (in-vehicle notification signal) in accordance with a prescribed process for acquiring the base station ID (step S11). If an in-vehicle notification signal (base station ID of the in-vehicle notification device 11) is detected at this time (YES in step S12), the process returns to step S11 and maintains the state as it is. If the in-vehicle notification signal is not detected (NO in step S12), the mobile phone unit 231 notifies the CPU 209 of cancellation of the telephone stop mode (NO in step S12) (step S13). Upon receiving the release notification, the CPU 209 sets the antenna mode to the incoming mode (step S14).

  When the telephone power is turned on: When the telephone power is turned on (step S21), the antenna mode is set to the weak mode (step S22). Then, the cellular phone unit 231 determines the presence / absence of an in-vehicle notification signal (step S23), and if no in-vehicle notification signal is detected, the mobile phone unit 231 proceeds to step S14 assuming that the vehicle is out of the train, and the portable telephone device 2 receives the antenna mode. Mode. On the other hand, if the in-vehicle notification signal is detected, the process proceeds to step S2.

  When the portable telephone device 2 is brought into the vehicle, the portable telephone device 2 receives the in-vehicle notification signal (in-vehicle base station ID) and automatically enters the weak mode. Incoming operation (ringer ringing) is not executed because it is difficult to receive radio waves from the mobile phone, and if the amplification of the transmitted radio waves is also reduced by the weak mode, the mobile phone itself performs the location registration and response The radio wave transmitted will be weak, and the impact on the heart pacemaker will be reduced.

  Further, in the above configuration, since the base station ID is received as the in-vehicle notification signal to detect whether it is in the vehicle, there is an advantage that it is not necessary to provide the in-vehicle notification signal receiving unit separately from the mobile phone unit 231. is there. Also, not only the base station ID, but also when performing in-vehicle determination based on information (broadcast control channel: BCCH) information on the transmission throttle (information indicating that it is in the vehicle here) There is an advantage that it is not necessary to separately provide an in-vehicle notification signal receiver. However, this does not exclude the provision of the in-vehicle notification signal receiving unit. For example, the in-vehicle notification device 11 sends out the in-vehicle notification signal on a specific frequency using a predetermined modulation method, and the portable telephone device. The in-vehicle notification signal receiving unit 2 may receive the radio wave of the specific frequency, perform demodulation processing, and take out the in-vehicle notification signal.

  In the above configuration, the antenna mode is set to the weak mode to result in the telephone stop mode. However, the present invention is not limited to this. With or without the weak mode, the CPU may control the mobile phone unit 232 to execute the telephone stop mode when receiving the in-vehicle notification signal. Examples of processing in such a telephone stop mode include processing such as no incoming operation (incoming melody, vibration) even when an incoming call is received, and no processing of emitting radio waves for location registration or response. It is done. In the configuration in which the in-vehicle notification signal receiving unit is provided separately, the telephone power supply may be turned off (power supply to the mobile phone unit 231 is stopped).

  Even in the stop mode, the entire power source of the portable telephone device 2 is not turned off, but the television / radio broadcast viewing by the terrestrial digital tuner 230 and the MPEG data stored in the memory card 3 can be viewed. For example, the CPU 209 may display a message that prompts the user to view the digital broadcast when the LCD panel 202 is presented to set the telephone stop mode.

  Regarding the data broadcast viewing by the terrestrial digital tuner 230, the portable telephone device 2 is configured such that a mode for prohibiting link connection from the data broadcast reception screen can be set based on a user operation. For example, an operation of pressing a button labeled “link prohibition” provided on the main body key 214, an operation of pressing a numeric keypad according to a combination of specific numbers indicating link prohibition, and a menu screen is called “link prohibition”. The prohibit mode is set by placing the cursor on the selected item and pressing the enter key.

  Next, processing related to the link prohibition mode will be described with reference to FIGS.

  Link prohibition mode setting (see FIG. 5): When a link prohibition mode setting command is received by a user operation (step S31), a message to set the link prohibition mode is presented on the screen (step S32). Next, the state of the TV power source (power source of the tuner 230, etc.) is checked (step S33), and if the TV power source is OFF, the process proceeds to step S37. If the TV power is ON (YES in step S33), it is determined whether or not the link connection is being made on the data broadcast reception screen (step S34). If the link is not being connected on the data broadcast reception screen, the process proceeds to step S37. If a link is being connected on the data broadcast reception screen (YES in step S34), a message is displayed on the screen to disconnect the communication for a predetermined time (eg, 10 seconds) (step S35), and the communication is disconnected. (Step S36). Then, the link prohibit mode is set (step S37), and the process is terminated. In setting the link prohibition mode, for example, “1” is set in a flag indicating ON / OFF of the link prohibition mode.

  Canceling link prohibition mode (see FIG. 6): Upon receiving a command to cancel link prohibition mode from the user (step S41), a message to cancel the link prohibition mode is displayed on the screen (step S42), and the link prohibition mode is turned on. "0" is set to the flag indicating / OFF (step S43). Release of the link prohibition mode is realized, for example, by calling a menu screen, placing the cursor on an item labeled “link prohibition release”, and pressing the enter key.

  Data broadcast communication process (see FIG. 7): When a link connection command is received on the data broadcast reception screen (step S51), the link prohibit mode ON / OFF flag is confirmed (step S52). If it is determined that the link prohibit mode is not set (NO in step S53), processing such as transmission of link information (URL, etc.) is performed (step S56). If the link prohibit mode is set (YES in step S53), a message indicating that the link prohibit mode needs to be canceled is displayed on the screen for a predetermined time (for example, 10 seconds), and the user cancels the link within this time. If YES in step S54, the link prohibit mode is canceled (step S55). Then, line connection processing is executed, and processing such as transmission of link information (URL, etc.) is performed (step S56). If not released (NO in step S54), the communication process is not executed and the process ends. That is, in the link prohibited mode, communication processing is not executed even if a link connection operation is performed on the data broadcast reception screen.

  In the above description, the communication processing is not executed in the link prohibited mode regardless of whether the portable telephone device 2 is in the vehicle. However, the portable telephone device 2 is The link prohibition process may be performed in addition to the condition that it is determined to be within. That is, it is also possible to determine whether or not the vehicle is in the vehicle in the determination process of step 53, and when it is determined that the link prohibit mode and the vehicle are in the vehicle, the process may proceed to step S54. Further, it is also possible to determine whether or not the vehicle is in the vehicle in the determination processing in step S34, and when it is determined that the link prohibit mode and the vehicle are in the vehicle, the process may proceed to step S35. In these cases, the “link prohibition mode” means that the link connection on the data broadcast reception screen is prohibited in the vehicle. In the “link prohibition mode” setting, for example, two items of “1. All links prohibited” and “2. In-vehicle links prohibited” may be prepared and selected by the user on the menu screen. As processing based on the in-vehicle determination, processing for enabling only the link prohibition mode without executing the above-described telephone stop mode may be performed, or processing for enabling the link prohibition mode together with the phone stop mode. You may go.

  Further, although an example in which the link prohibition mode is set in the portable telephone device 2 has been shown, a configuration in which the link prohibition mode can be set also in the stationary digital broadcast receiving device may be adopted. In that case, for example, it is possible to prevent a trouble that a child operates and connects to a paid site without knowing and is charged, and this is effective in preventing mischief of the child.
