  FIG. 5 is a flowchart of the program reservation process executed by the CPU 209 in FIG.

  In FIG. 5, when the viewer makes a program viewing reservation from the electronic program guide 40, the CPU 209 determines whether or not the start time of the program to be reserved is later than the current time (step S101). When the start time is not later than the current time, that is, when the current time has passed the start time, this process is terminated, and when the start time is later than the current time, reservation registration is performed (step S102) ( Program registration means).

  In the reservation registration in step S102, information such as the start time and channel number of the program to be reserved is temporarily stored in the storage area inside the CPU 209, and the program (reserved program) reserved and registered in the electronic program guide 40 is stored. This is done by giving a symbol indicating that the reservation has been registered (registered program sign means).

  Next, in the displayed electronic program guide 40, the time slot of the reserved program is colored over all the channels in order to indicate the time slot where the reserved program is present (step S103) (registered time zone indicator means).

  For example, in FIG. 4, when the program 22 of the channel number CH102 is reserved and registered, as shown in FIG. 6, a symbol (here, an asterisk) indicating that the program 22 has been reserved and registered is given. The time zone from 19:00 to 20:30, which is the scheduled broadcast time of the program 22, is colored over all channels in the electronic program guide 40.

  Returning to FIG. 5, in step S <b> 104, the CPU 209 monitors the start time of the reserved program. If the start time is close (YES in step S <b> 105), the channel number of the broadcast currently being reproduced on the display device 219 is displayed. It is determined whether or not the channel number of the reserved program matches, that is, whether or not the channel of the reserved program is being reproduced (step S106). When the channel of the reserved program is being reproduced, the reserved registration performed in step S102 is deleted. After (step S112), the coloring performed in step S103 is erased (step S113), and this process ends.

  If the result of the determination in step S106 is that the reserved program channel is not being played back, a message notifying that the reserved program start time is near is displayed on the display screen (step S107), and at the same time, the message is displayed. Measurement of the time is started (step S108).

  For example, when the program 22 of channel number CH102 is reserved and registered, and the start time of the reserved program is approaching, as shown in FIG. 7, a message 51 “Reserved on CH102” is displayed on the display device 219. Is displayed.

  Returning to FIG. 5, whether or not the channel number of the broadcast to be reproduced has been changed by the viewer (step S109) and whether or not a predetermined time has elapsed since the message was displayed in step S107 (step S110). When the channel number of the broadcast to be discriminated and reproduced is changed by the viewer (YES in step S109), or when a predetermined time has elapsed since the message was displayed (YES in step S110), it is displayed in step S107. The deleted message is deleted (step S111), the processing after step S112 is executed, and this processing ends.

  According to the processing of FIG. 5, in the displayed electronic program guide 40, the time slot of the reserved program is colored over all channels in order to indicate the time slot where the reserved program exists (step S103). As shown in FIG. 8, even if the channel of the reserved program in the electronic program guide 40 is not displayed on the display device 219, the viewer can be informed that there is a reserved program in the colored time zone. Accordingly, it is possible to notify the viewer of the reservation status without providing a column indicating the reservation status separately from the program column.

  Hereinafter, a second embodiment of the present invention will be described with reference to the drawings.

  In the first embodiment of the present invention, the viewing reservation is performed in units of programs (step S102). For example, in the electronic program guide 40 of FIG. 6, after the viewing reservation of the program 22 of the channel number CH102 is performed, Since it is not possible to make a viewing reservation for the latter half of the program 32 with the channel number CH103, the present embodiment sets a time slot for making a viewing reservation for each channel of the electronic program guide 40, as shown in FIG. By providing the time zone setting area 41, it is possible to make a viewing reservation for an arbitrary time zone in addition to the viewing reservation for each program.

  In FIG. 9, an electronic program guide 40 generated by the CPU 209 sets a time zone for making a viewing reservation, and sets a time zone setting area 41 provided for each channel, a program on the electronic program guide 40, and a time zone setting area. A cursor 42 for selecting 41 is displayed.

  In the present embodiment, for example, as shown in FIG. 10, in the state where viewing / listening of the program 22 with the channel number CH102 is reserved, viewing reservation for the time zone from 20:30 to 22:00 of the program 43 with the channel number CH104 is performed. Can be performed by the time zone setting area 41.

  FIG. 11 is a flowchart of the program reservation process executed by the CPU 209 in FIG.

  In this process, on the time zone setting area 41, the viewing reservation start time is set using the upper button of the cross button 237 of the remote controller 215, and the viewing reservation end time is set using the lower button of the cross button 237. Shall.

  In FIG. 11, first, on the screen displaying the electronic program guide 40, when the upper button of the cross button 237 of the remote control 215 is pressed on the time zone setting area 41 where the viewing reservation is made (YES in step S201). ) The reservation start time is designated and time measurement is started (step S202), and it is determined whether the cursor is moved by the ring button 238 or the lower button of the cross button 237 is pressed (step S203). When the cursor is not moved and the lower button of the cross button 237 is not pressed, it is determined whether or not a predetermined time has elapsed since the start of time measurement (step S204), and the predetermined time has elapsed. If not, the process returns to step S203, and when the predetermined time has elapsed, if the time zone setting area 41 is colored, the coloring is returned to the original state (scanning). -Up S205), and terminates the process.

  If the result of determination in step S203 is that the cursor has been moved or the down button of the cross button 237 has been pressed, it is determined whether or not the cursor has been moved (step S206), and if the cursor has been moved, The time zone setting area 41 is colored between the start time of the viewing reservation designated by pressing the upper button of the cross button 237 in step S201 and the position where the cursor is moved (step S207), and the processing after step S202. repeat.

  In step S201 to step S207, for example, after the reservation start time is set by pressing the upper button of the cross button 237 at the time of 20:30 of the channel number CH104 in step S201, the cursor 42 is near 22:00 in step S206. 12, the time zone setting area 41 of the channel number CH104 in the electronic program guide 40 is colored in the time zone from 20:30 to 22:00, as shown in FIG. When the reservation start time is set with the up button of the cross button 237 in step S201, the cursor 42 needs to be positioned on the time zone setting area 41, but after that, the cursor 42 is on the time zone setting area 41. The time zone setting area 41 is colored in a range from the set reservation start time to the time when the moved cursor 42 is located.

  Returning to FIG. 11, when the cursor is not moved as a result of the determination in step S206, that is, when the lower button of the cross button 237 is pressed, the reservation end time is designated, and the viewing reservation of FIG. A confirmation screen 60 is displayed (step S208).

  As shown in FIG. 13, the viewing reservation confirmation screen 60 includes a viewing reservation content 61 including a channel number, a reservation start time, and a reservation end time, an OK button 62 for confirming the viewing reservation content 61, and a viewing reservation content. And a cancel button 63 for canceling 61. The OK button 62 and the cancel button 63 can be pressed by moving the cursor 42 onto the button to be pressed and pressing the enter button 236.

  Returning to FIG. 11, when either the OK button 62 or the cancel button 63 is pressed on the viewing reservation confirmation screen 60 in step S209, it is determined whether or not the OK button 62 has been pressed (step S210). When the button 62 is not pressed, that is, when the cancel button 63 is pressed, the coloring of the time zone setting area 41 is restored (step S205), and this process is terminated.

  If the OK button 62 is pressed as a result of the determination in step S210, reservation registration is performed (step S211) (time zone registration means), and then an electronic program guide display process shown in FIG. In S212, a display indicating that there is a reserved time zone in the electronic program guide 40 is displayed, and this process is terminated. The reservation registration in step S211 is performed by temporarily storing the contents displayed on the viewing reservation confirmation screen 60 in a storage area inside the CPU 209.

  After the electronic program guide display process is executed in step S212, the program reserved for viewing is reproduced by the same process as the process after step S104 in FIG.

  According to the processing of FIG. 11, when the time zone setting area 41 is provided in the electronic program guide 40 and the upper button of the cross button 237 is pressed on the time zone setting area 41 for making a viewing reservation (YES in step S201). When the reservation start time is specified (step S202) and the lower button of the cross button 237 is pressed (NO in step S206), the reservation end time is specified (step S208), so that viewing in an arbitrary time zone is performed. Reservations can be made.

  FIG. 14 is a flowchart showing the electronic program guide display process in step S212 of FIG.

  In FIG. 14, first, it is determined whether or not the reservation start time reserved and registered in step S211 of FIG. 13 is the same as the start time of the program of the channel reserved for viewing that is displayed in the electronic program guide 40. (Step S301) If it is not the same as the start time of the program, a boundary line is displayed at the reservation start time of the channel reserved for viewing (Step S302). If it is the same as the start time of the program, Step S302 is executed. The process proceeds to step S303 without performing the above process.

  Next, it is determined whether or not the reservation end time reserved and registered in step S211 of FIG. 13 is the same as the end time of the program of the channel reserved for viewing displayed in the electronic program guide 40 (step S303). If it is not the same as the program end time, a boundary line is displayed at the reservation end time of the channel reserved for viewing (step S304), and if it is the same as the program end time, the process of step S304 is performed. Without proceeding to step S305.

  Next, a symbol indicating that the reservation has been registered is added to the reserved time zone (step S305) (region marking means), and the time zone of the reserved program is set to all channels in order to indicate the time zone in which the reserved program exists. (Step S306), and the process is terminated.

  For example, in FIG. 10, when the time zone from 20:30 to 22:00 of the channel number CH104 is reserved and registered, as shown in FIG. 15, the time of 20:30 of the program 43 and 22:00 of the program 44 In step S302 and step S304 in FIG. 14, a boundary line (in this case, a dotted line) that is different from the partition line for each program is displayed, and in step S305, the boundary line of the program 44 at 22:00 is displayed. A symbol indicating that the reservation has been registered (in this case, an asterisk) is given, and further, all channels in the electronic program guide 40 are registered in the time zone from 20:30 to 22:00 reserved and registered in step S306. Colored across.

  According to the processing of FIG. 14, boundary lines are displayed for the reservation start time and reservation end time of the channel reserved for viewing (step S302, step S304), indicating that the reservation is registered in the reserved time zone. Since a symbol is added (step S305) and the time zone of the reserved program is colored over all channels (step S306), the viewer can be informed of the time zone and channel reserved and registered.

  The third embodiment of the present invention will be described below with reference to the drawings.

  In the second embodiment described above, since the time slot for making the viewing reservation is specified using the cursor, the specified time slot is ambiguous. Therefore, in this embodiment, the time provided in the electronic program guide 40 When the viewing reservation is made in the band setting area 41, the start time and the end time of the time slot for viewing reservation are adjusted after the time zone for performing the viewing reservation is designated using the cursor.

  FIG. 16 is a flowchart of the program reservation process executed by the CPU 209 in FIG.

  In FIG. 16, the same steps as those in FIG. 11 are denoted by the same reference numerals, and the description thereof is omitted.

  In FIG. 16, when the cursor is not moved as a result of the determination in step S206, that is, when the lower button of the cross button 237 is pressed, the reservation end time is designated, and the viewing reservation confirmation in FIG. The screen 60 is displayed (step S401).

  As shown in FIG. 17, the viewing reservation confirmation screen 60 includes a viewing reservation content 61 including a channel number, a reservation start time, and a reservation end time, an OK button 62 for confirming the viewing reservation content 61, and a viewing reservation content. 61 has a cancel button 63 for canceling 61, a start time selection area 64 for selecting a reservation start time, and an end time selection area 64 for selecting a reservation end time.

  Returning to FIG. 16, in step S <b> 402, it is determined whether any of the start time selection area 64 and the end time selection area 64 is pressed on the viewing reservation confirmation screen 60, and the start time selection area 64 and the end time selection area are determined. When any one of 64 is pressed, a reservation time changing process shown in FIG. 18 described later is executed (step S403), the ambiguous reservation time setting by the cursor is adjusted, and the start time selection area 64 and the end time selection are selected. If neither area 64 is pressed, the process proceeds to step S404 without executing the reservation time changing process in step S403.

  Next, it is determined whether or not either the OK button 62 or the cancel button 63 has been pressed (step S404). If neither the OK button 62 nor the cancel button 63 is pressed, the process returns to step S402, and the OK button 62 and the cancel button are cancelled. When any of the buttons 63 is pressed, the processing after step S210 is executed, and this processing is terminated.

  According to the process of FIG. 16, when either the start time selection area 64 or the end time selection area 64 is pressed (YES in step S402), the reservation time change process of FIG. 18 described later is performed (step S403). So you can adjust the ambiguous reservation time setting with the cursor.

  FIG. 18 is a flowchart of the reservation time change process in step S403 of FIG.

  In FIG. 18, when one of the start time selection area 64 and the end time selection area 64 is pressed in step S <b> 402 of FIG. 16, the reservation start time or the reservation end time is advanced or delayed by the up and down buttons of the cross button 237. When the viewer adjusts the reservation start time or the reservation end time with the up and down buttons of the cross button 237 (step S501), the time zone from the adjusted reservation start time to the reservation end time is set. Then, it is determined whether or not it overlaps with a time slot that has already been registered for registration (step S502). If it overlaps with a time slot that has already been registered for reservation, the time adjustment is invalidated (step S503), Returning to S501, when the decision button 236 is pressed without overlapping the time zone that has already been registered for reservation (step S504). YES), the time after adjustment becomes effective, the reserved time is changed (step S505), the process ends.

  According to the process of FIG. 18, the viewer adjusts the reservation start time or the reservation end time with the up and down buttons of the cross button 237 (step S501), and the time zone from the adjusted reservation start time to the reservation end time is If the decision button 236 is pressed without overlapping the time zone that has already been registered for registration (YES in step S504), the reservation time is changed (step S505) (time zone adjusting means), so the cursor is ambiguous. The reservation time setting can be adjusted.
