When the up / down / left / right direction key part of the cross key (with OK key) 82 is pressed, the cursor can be moved upward, downward, leftward, and rightward, respectively. Become.

  FIG. 2 is a block diagram showing a circuit configuration of the portable telephone device 30. Reference numeral 1 denotes an antenna that receives television broadcast waves, and reference numeral 2 denotes an antenna that transmits and receives radio waves from a mobile phone. Depending on the configuration, the antennas 1 and 2 that receive two radio waves can be shared.

  The tuner module 4 performs processing for receiving a digital television broadcast wave and demodulating the modulated wave. An application processor (APP) 5 performs digital television reception processing. The application processor 5 performs a function of receiving demodulated data from the tuner module 4 to generate video / audio and other functions necessary for the operation of the digital television. A CPU for performing these various processes, MPEG4, etc. It is composed of an LSI in which processing circuits for decoding audio data such as a video data decoder and AAC are combined.

  The baseband chip (BB) 3 is used to control incoming / outgoing calls, telephone calls, network connections, etc. of mobile phones, and various circuits and CPUs that perform modulation / demodulation, signal processing and call processing necessary for mobile phones are combined. It is made of LSI. In this embodiment, the baseband chip (BB) 3 creates a standby screen, a call screen, a mail screen (creation / reception), and the like.

  A memory 9 is connected to the baseband chip 3, and a memory 10 is connected to the application processor 5. The memories 9 and 10 are composed of a flash memory (nonvolatile memory) for storing programs and various setting data and a DRAM used for work. The display device 6 is connected to the baseband chip 3 and the application processor 5 and displays the result of each processing. The speaker device 7 is connected to the baseband chip 3 and the application processor 5 and outputs sound (including ringtone) based on the respective output sound signals. The input device 8 includes various keys, which will be described later, and is connected to the baseband chip 3.

  The display device 6 includes, for example, a liquid crystal display panel, a backlight, and a driver. The driver drives the liquid crystal display panel based on the input video data, performs panel drive control based on the designated contrast setting information, and emits light from the backlight based on the designated brightness setting information. (Supply power) is controlled.

  The speaker device 7 includes, for example, a D / A converter that converts input audio data into an analog audio signal, an amplifier that amplifies the analog audio signal, and a speaker. The amplifier amplifies the analog audio signal based on the designated amplification factor (volume setting information).

  When the baseband chip 3 detects a user operation requesting TV viewing (not limited to a request from the menu screen, for example, an operation of “TV button” provided in the input device 8, for example), the application processor 5 The broadcast receiving process is instructed, and the process of switching the input of the display device 6 and the input of the speaker device 7 to the application processor 5 side is executed. Both the baseband chip 3 and the application processor 5 can determine whether the current state is the TV viewing mode or the telephone mode.

  The flash memory of the memory 9 connected to the baseband chip 3 stores image / sound related information (including when waiting for a call, when creating a mail, when making various settings, etc. other than when watching TV). Contrast information, screen brightness information, volume information, etc.) are stored. These pieces of information can be changed by a user operation (such as an operation on the menu screen).

  Further, in this embodiment, the information on the image / sound in the TV viewing mode (contrast information, screen brightness information, volume information, etc. in the TV viewing mode) is also flashed in the memory 9 connected to the baseband chip 3. Stored in memory. The baseband chip 3 reads the relevant information of the image / sound in the TV viewing mode from the memory 9 and gives the relevant information to the application processor 5 when instructing the application processor 5 to perform broadcast reception processing.

  Next, processing of the baseband chip 3 and processing of the application processor 5 will be described. When the portable telephone device 30 is powered on, the baseband chip 3 first performs an initial process. The initial processing includes clearing the memory (DRAM), initializing the input device 8, and initializing the display device 6 and the speaker device 7. In initialization of the display device 6 and the speaker device 7, the baseband chip 3 performs driver setting of the display device 6 and setting of the speaker 7 based on the image / sound related information in the telephone mode read from the memory 9. For example, the driver sets the backlight brightness (power supply) based on the screen luminance information, and the speaker 7 sets the amplification factor. When initialization is completed, a standby screen is displayed and some event is awaited. Events include key entry, incoming call, incoming mail, and battery check timer. When an event occurs, processing is divided according to the type of the event. If it is determined that the event is a press of the menu key 81, the baseband chip 3 displays the main menu on the display device 6.

  The baseband chip 3 determines a key code generated when each key of the input device 8 is operated. For example, a key code generated when the upper end of the cross key 82 is pressed (key code of the upward key). If there is, move the cursor on the menu screen upward. If the key code is generated when the center of the cross key 82 is pressed (OK key key code), the process proceeds to execution of the content of the item where the cursor is located. If this item is “TV viewing”, the baseband chip 3 activates the application processor 5 and notifies the application processor 5 of a TV viewing function start command. With this command, the application processor 5 starts TV viewing processing.

  When the command is notified, the baseband chip 3 reads the image / sound related information in the TV viewing mode from the memory 9 and gives it to the application processor 5. The application processor 5 writes the related information in the memory 10 (DRAM), and sets the driver of the display device 6 and the speaker 7 based on the related information. For example, the driver sets the brightness of the backlight (power supply) based on the screen luminance information that is the related information, and the speaker 7 sets the amplification factor. Then, the application processor 5 gives the received video data from the tuner 4 to the driver of the display device 6 and gives the received audio data to the speaker device 7.

  In the TV viewing mode, for example, it is conceivable that the up / down direction key of the cross key 81 functions as a channel up / down key and the left / right direction key functions as a volume up / down key. The baseband chip 3 transfers the input key code to the application processor 5. The application processor 5 determines a request based on the transferred key code, and executes channel up / down and volume up / down processing. When performing the volume up / down processing, the application processor 5 writes the changed setting value by the up / down in the memory 10 (DRAM). A change set value is sent to the baseband chip 3 each time, or a final set value is sent when the TV viewing mode ends. The baseband chip 3 stores (rewrites) the received changed setting value or final setting value in the flash memory of the memory 9 as a new setting value.

  In this embodiment, when the user presses a predetermined key for a long time during TV viewing, the baseband chip 3 determines that the predetermined key is pressed and gives the application processor 5 the pressing information of the predetermined key. If the pressed information indicates the contrast setting, the application processor 5 generates an image in which the current contrast value is superimposed (superimposed) on the screen of the received program, for example. For example, when the key code of the cross key 82 is transmitted to the application processor 5 via the baseband chip 3, the application processor 5 changes the contrast setting value based on the key code. When changing the contrast setting value, the application processor 5 writes the changed setting value in the memory 10 (DRAM). A change set value is sent to the baseband chip 3 each time, or a final set value is sent when the TV viewing mode ends. The baseband chip 3 stores (rewrites) the received changed setting value or final setting value in the memory 9 as a new setting value.

  When there is an incoming call in the telephone mode (in the standby state), the baseband chip 3 outputs a preset ring tone from the speaker device 7. The volume is based on the image / sound related information in the telephone mode stored in the memory 9. If vibration is set, a vibrator (not shown) is driven when an incoming call is received. On the other hand, when an incoming call is received in the TV viewing mode, the baseband chip 3 performs processing based on the image / sound related information in the TV viewing mode stored in the memory 9. If the related information is “no ringtone”, no ringtone is output from the speaker device 7. If the baseband chip 3 is “with ringtone”, the speaker device 7 is switched to the own side, and the speaker device 7 is driven based on the incoming sound volume information in the TV viewing mode. With respect to this ringing volume information, a setting for lowering the ringing tone in the telephone mode will be selected by the user.

  When displaying the standby screen in the telephone mode, the baseband chip 3 drives the display device 6 with high luminance, and starts counting the timer, and drives the display device 6 with low luminance after a predetermined time has elapsed. . The information related to the predetermined time is based on the image / sound related information in the telephone mode stored in the memory 9. On the other hand, when the baseband chip 3 causes the application processor 5 to execute the TV viewing process, if the information related to the predetermined time exists as image / sound related information in the TV viewing mode, this information is sent to the application processor 5. To do. As a result, for example, the standby screen in the telephone mode can be displayed with a low luminance in about 5 seconds, for example, and the received program screen in the TV viewing mode can have a low luminance in 30 minutes. Luminance information for low luminance may be stored as image / sound related information in the TV viewing mode. Further, if there is no information about the predetermined time as the image / sound related information in the TV viewing mode, the information about the predetermined time is not sent to the application processor 5, so that the display device 6 has a predetermined luminance without time limitation. Will be maintained.

  In the above embodiment, the processing of the CPU of the baseband chip 3 and the CPU of the application processor 5 are shared. However, the processing of the telephone mode and the TV viewing mode may be performed by one CPU. Good. Also, the way of sharing is not limited to the above-described examples. Further, the image / sound related information in the TV viewing mode is stored in the memory 9 (nonvolatile memory) connected to the baseband chip 3, but the memory 10 (nonvolatile memory) connected to the application processor 5 is used. ) May be stored.
