  That is, when the control unit 8 detects that the date item has been selected, the control unit 8 then performs the day-of-week display process for causing the user to select the day of the week based on the operation signal of the cross key 21.

  The user presses the enter key 22 when the date to be selected is displayed (step 103).

  The control unit 8 temporarily registers information on the day of the week when the enter key is pressed (maintains the display state of the day of the week).

  When the left arrow key is operated, the date is displayed in the reverse order.

  As described above, when the enter key is pressed for the day of the week, the control unit 8 moves the cursor to the start time item as shown in FIG.

  The user operates the left and right arrow keys of the cross key 21 to change the time.

  Specifically, since the time changes in ascending order for the right arrow key and the descending order for the left arrow key, the determination key 22 is pressed when the desired time is displayed, as in the case of the above date. (Step S103).

  That is, when the cursor is positioned at the start time item, the control unit 8 performs a process of changing the display time based on the operation information of the cross key 21, and when the pressing of the enter key 22 is detected, Is temporarily registered (the display state of the start time is maintained).

  When the enter key 22 is pressed with respect to the start time as described above, the control unit 8 moves the cursor to the end time item as shown in FIG.

  The user operates the left and right arrow keys of the cross key 21 to determine the time.

  That is, the control unit 8 performs a process of changing the display time based on the operation information of the cross key 21 when the cursor is positioned at the end time item. Is temporarily registered (the display state of the end time is maintained).

  When the determination key 22 is pressed with respect to the end time as described above, the control unit 8 moves the cursor to the channel item as shown in FIG.

  If the user knows the channel of the desired program (NO in step S106), the user presses the numeric key 27 to select the channel, and presses the enter key 22 to determine the channel (step S113).

  On the other hand, if the channel of the desired program is not known (YES in step S106), the user inputs characters using the numeric keypad 27 and presses the enter key 22 to specify the desired program name (step S107).

  That is, the control unit 8 processes a signal from the numeric keypad 27 as program name specifying information for receiving a television broadcast.

  In this embodiment, the control unit 8 performs an EPG (electronic program guide) search to search for a channel to which a program that matches the specified program name belongs (step S108).

If the program channel is not found, the program search is performed again (YES in step S106, step S107, step S108), or the user finds the channel and inputs the channel (step S113).

  If the channel of the desired program is found (YES in step S109), the channel number is displayed as shown in FIG. 6D, and the channel is determined by the user pressing the enter key 22 (step S111). ).

  As described above, scheduled recording is set based on the determined reservation content (step 112).

  That is, the control unit 8 records in the reservation memory information specifying the program channel for which the recording reservation is determined and the reception reservation date and time.

  Various methods are conceivable as a method for setting reservation recording.

  For example, the scheduled recording is set by pressing the power key 26 to turn off the power.

  That is, when the control unit 8 determines that the power key is turned off, the control unit 8 sets the channel and the reception reservation date / time of the program to be scheduled for recording in the recording reservation information memory.

  With this method, since the telephone does not receive a call during the scheduled recording setting, the recording is not disturbed.

  Further, as other setting methods for reserved recording, various methods such as simultaneously pressing the TV key 25 and the recording key 28, or pressing and holding the recording key 28 can be considered.

  Further, as shown in the reservation recording selection items shown in FIG. 5, the F key 23 may be operated so that the reservation recording can be set from the menu.

  Even if the power key 26 is pressed and the power is turned off, the energization of the control unit 8 is maintained, for example, in the case of the reservation recording setting state.

  The control unit 8 has a calendar function for determining the current date and time, performs a tuning process for receiving the reserved program when it is determined that the scheduled reception date and time is received, executes energization to the memory for recording, and receives The video and audio of the program are A / D converted and recorded in the memory.

  (Embodiment 2) In the case of data broadcasting of terrestrial digital broadcasting, when character input or the like is involved, the character input method of a mobile phone is used.

  Specifically, a mobile phone has a character input function such as e-mail creation conventionally, and the character input function of the mobile phone is applied to a data broadcast operation of digital broadcasting.

  For example, the character input function of a mobile phone can be performed by assigning a numeric key to each row of the 50-sound table (assigning “A” row to 2 keys, “or” row to 2 keys, etc.) Is a method to be selected.

  For example, when “9” key is pressed for the first time, “Ra line” is specified, and every time the “9” key is pressed, “R, R, R, R, R, R, ...” is selected cyclically. It will follow.

For example, when the “9” key is pressed three times and “RI” is input and the “8” key is pressed, “RIYA, RIYU, RIYO, RYA, RYU, RI "" Is specified.
In upper wave digital broadcasting, the frequency channel allocation of broadcasting stations differs depending on the region.

  Therefore, when the mobile device is moved, a situation occurs in which a program that was viewed at a certain point is broadcast on a different channel at another point.

  Therefore, in the present invention, the broadcast station (channel) and the program to be viewed are input as characters, and a channel search is performed according to the character input to perform automatic channel selection.

  This is the same as the processing from step S106 to step S111 at the time of the reserved recording in FIG. 4, and a desired program can be searched for and viewed by a similar operation in normal analog TV viewing.

  As described above, in terrestrial broadcasting, the frequency channel allocation of broadcasting stations differs depending on the region.

  Therefore, since it becomes necessary to change the channel setting according to the position at that time, the channel setting may be automatically changed by performing a channel search periodically, for example, at intervals of 1 minute.

  Alternatively, as described in Japanese Patent Application No. 2002-302062 and Japanese Patent Application No. 2002-325831, it may be set using a correspondence table between position information and channel settings.

  First, a text input method in data broadcasting will be described.

  In data broadcasting, video data and text data can be received.

  In this case, as shown in FIG. 11A, video display can be performed using the upper half area of the LCD panel 202, and a text screen can be displayed using the lower half area.

  FIG. 11A shows a user registration screen as a text screen.

  The user performs text input using the main body key 214.

  Here, in the registration screen in the conventional data broadcasting, a stationary large screen television is taken into consideration, a 50-tone dial is displayed on the screen, the cursor is positioned on a desired character with the cross key, and the enter key The input is performed one character at a time (for example, in the registration screen of the NHK BS-1 data broadcast).

  On the other hand, in the portable device of the present invention, text input can be performed using the main body key 214 (a character input function of a mobile phone can be used), and a plurality of characters can be easily input. The operability is improved as compared with the conventional method.

  As a specific input method, as shown in FIG. 11B, character input is performed on the item where the cursor is displayed.

  The cursor is moved by operating the cross key, and the input frame is changed.

  A flowchart of text input is shown in FIG.

  When the data broadcast is displayed (step S201), it is determined whether the content has character input (step S202).

  For example, since a BML file is transmitted in data broadcasting, the CPU 209 (browser) can make the above determination based on whether a description for character input exists in the BML file.

  If the content has no character input, the process ends.

  On the other hand, when determining that the content has character input, the CPU 209 detects an operation of the main body key 214 (step S203) and executes character input processing (step S204).

  When the CPU 209 detects that the enter key 22 is pressed while the cursor is positioned on the “cancel” button on the screen (YES in step S205), the CPU 209 deletes the input character data (step S206). Return to S204.

  On the other hand, when the CPU 209 detects that the enter key 22 is pressed while the cursor is positioned on the “Register” button on the screen (YES in step S207), the CPU 209 ends the character input process (step S209). (NO in steps S205 and S207), the process returns to step S204 and continues.

  Also, when there is an input other than the cross key 21, the enter key 22, and the numeric keypad 27 (YES in step S208), the character input is terminated (step S209).

  The following three methods are conceivable as TV selection methods.

  The first method assigns a service (channel) to each of the numeric keys 27 in advance and selects a channel by pressing a button (one-touch channel selection). The second method uses a channel up / down key. A method of selecting a channel by using (up / down channel selection), and a third method of selecting a channel by directly specifying a 2-digit or 3-digit number using the numeric keypad 27 (direct channel selection). is there.

  The portable device of this embodiment corresponds to the above three channel selection methods.

  Which channel selection method (channel selection mode) is selected may be registered in advance on the menu screen, for example.

  The first method is as described in the first embodiment.

  In the second method, a key corresponding to a channel number up / down key of a remote controller is assigned to a key of a mobile phone (for example, an up / down key of a cross key).

  When the up key is pressed, the channel next to the currently selected channel is selected.

  Conversely, if the down key is pressed, the channel before the currently selected channel is selected.

  The order of channel selection transition using the up / down key is performed in accordance with the correspondence table (see FIG. 9A) between the numeric keypad and the broadcasting station.

  The next channel described above means a channel in which the numeric value of the numeric keypad is next described in the table.

  Similarly, the previous channel means the channel in which the numeric value of the next numeric keypad described in the table is smaller.

  FIG. 13 shows a flowchart of up / down channel selection.

  If there is an up channel selection (when the up key is pressed) (YES in step S301), the channel number currently selected is referred to (step S302).

  Further, the ten key / broadcast service correspondence table is referred to (step S303), and it is determined whether or not the current channel is described at the end of the table (step S304).

  If not listed at the end of the table, the next channel number in the table is acquired (step S305), and the process proceeds to step S313.

  On the other hand, if it is described at the end of the table, the head channel number in the table is acquired (step S306), and the process proceeds to step S313.

  When there is down channel selection (when the down key is pressed) (YES in step S307), the channel number currently selected is referred to (step S308).

  Further, the ten key / broadcast service correspondence table is referred to (step S309), and it is determined whether or not the current channel is described at the head of the table (step S310).

  If it is not described in the head of the table, the previous channel number in the table is acquired (step S311), and the process proceeds to step S313.

  On the other hand, if it is described at the head of the table, the channel number at the end of the table is acquired (step S312), and channel selection is performed based on the acquired channel number (step S313).

  In the third channel selection method, for example, a window (see FIG. 14A) for inputting a 2- or 3-digit channel number by pressing the TV key or the like is displayed at the lower right position of the LCD panel 202 or the like. To do.

  Then, by inputting an arbitrary 2- or 3-digit numerical value using the numeric keypad, the channel of the input number is selected.

  A flowchart of direct channel selection is shown in FIG.

  Here, it is assumed that a 3-digit numerical value needs to be input.

  When the CPU 209 detects that the TV key 25 is pressed while the direct channel selection mode is preset (YES in step S401), the CPU 209 displays a window on the screen (step S402).

  The CPU 209 receives a signal from the numeric keypad operated by the user and performs numerical value input processing (step S403), and determines whether or not the numerical value input is completed (step S404).

  The end determination is made when a three-digit numerical value is input.

  If it is determined that the numerical value input has been completed, channel selection is executed based on the input numerical value (step S405).

  If it is determined that it has not been completed (NO in step S404), a timeout of direct channel selection is determined (step S406).

  If it is determined that the time is out, the process is terminated. If it is determined that the time is not out (NO in step S406), it is determined whether there is a direct channel stop input (step S407).

  If there is a direct tuning stop input, the process is terminated. If it is determined that there is no direct tuning stop input (NO in step S407), the process returns to step S404.

  The direct channel selection stop input is generated, for example, when a key other than the numeric keypad is operated.
