DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a digital broadcast receiving apparatus for receiving a digital broadcast.

[0002]

2. Description of the Related Art Image compression using digital signal compression technology
There is digital broadcasting that compresses audio signals and broadcasts a stream (transport stream) obtained by time-division multiplexing of video and audio digital signals of a plurality of programs via a transponder (satellite repeater). Since there are a plurality of transponders, and a plurality of channels are multiplexed on each transponder, the number of channels is as large as hundreds or more. On the other hand, a broadcast receiving apparatus that receives such a digital multi-channel broadcast selects one of a plurality of transponders of the digital broadcast received through a dedicated antenna by a tuner, and selects a plurality of channels included in the one transponder. One of them is selected by demultiplex processing, and a video / audio signal is output by decoding a digital signal of the selected channel.

[0003] In such digital television broadcasting, functions that are not included in conventional analog broadcasting, such as information on programs currently being broadcasted and programs to be broadcasted in the future, and service information such as notification from a communication carrier, are inherently provided. It is transmitted at predetermined time intervals together with the program data. Further, current time information is also transmitted. The digital broadcast receiving apparatus receives the service information and performs an EPG (Electronic
c Program Guide) Since the program guide is displayed as a program guide on the display by the screen display function, the user can efficiently select a program to be viewed from the multi-channel broadcast. The program reservation function enables EP
A program on the G screen can be reserved. In the reservation function, confirmation of reservation contents is performed, and when a program start time arrives, a channel of a reserved program is automatically selected and notified to a user.

[0004]

By the way, there is a close relationship between program reservation and reservation recording and the user's action schedule. For example, program reservation can be made when a program that the user wants to watch is broadcast during the time when the user is at home, and program reservation recording can be performed when the program that the user wants to watch is broadcast during the time when the user is out. It is customary. In this case, the user performs program reservation or reservation recording based on a remembered schedule (own schedule) or while looking at the schedule notebook. As described above, although there is a close relationship between performing a program reservation or scheduled recording and a user's action schedule, conventionally, a user's schedule needs to be managed by the user himself, The schedule related to program viewing was to be performed by the digital broadcast receiving apparatus using an EPG screen display function, a timekeeping function, or the like.

It is an object of the present invention to provide a digital broadcast receiving apparatus capable of managing a user schedule.

[0006]

A digital broadcast receiving apparatus according to the present invention comprises: first information display means for displaying a program table on a screen based on service information included in digital broadcast;
First information input means for receiving a scheduled date and time for viewing a digital broadcast, and timing means for monitoring arrival of the scheduled date and time;
A second information input unit for receiving an input of the scheduled date and time of the user and the content of the schedule; and a second information display unit for displaying a screen of the input scheduled date and time of the user and the content of the input. .

With the above configuration, the digital broadcast receiving apparatus can be used as a user's schedule management apparatus. That is, the user can view the user's own schedule with the same operation and feeling as viewing the program guide on the screen.

[0008] The second information input means is configured to receive an input of information presentation date and time, and the clocking means is configured to monitor the date and time based on the scheduled action date and time or the arrival of the information presentation date and time. Preferably, the second information display means is configured to display a screen of the input scheduled date and time of the action of the user and the content of the schedule when the date and time reached by the monitoring of the clock means. Here, for example, a display item of the user calendar is provided as one of the menu operations, and when this item is operated, a screen display of the scheduled date and time of the user and the contents of the schedule may be performed. It is necessary to make a habit of confirming the schedule by menu operation. As in the above configuration, if the screen is automatically displayed at the time of the information presentation date and time, even when the schedule presentation operation is neglected, the broadcast receiving apparatus reliably presents the user schedule. Will be.

It is preferable that the display of the program guide on the screen by the first information display means and the screen display of the scheduled action date and time of the user by the second information display means are simultaneously performed. According to this, the user's action schedule and program schedule can be directly compared and viewed,
Processing such as program reservation corresponding to the user's scheduled action becomes easier.

[0010] It is desirable that the program viewing unavailable time zone is determined based on the input scheduled date and time of the user's action, so that the display form of the program guide in the time zone is different from the normal display. According to this, it is easy to focus on a program to be broadcasted during a program viewing unavailable time zone such as a user's outside time zone or bedtime time zone. Further, it is easy to determine the reservation mode (viewing only, recording only, viewing + recording).

“Wakeup time”, “outing time”, “return time”, and “bedtime” are prepared. The figure shows a case where a notification setting (designation of a schedule presentation time) is made for “going out time”. In the basic setting of the personal schedule, different settings may be made between weekdays and weekends. Although not shown, a keyboard screen (not shown) is also displayed on these screens, and the user can input characters by operating, for example, left / right / up / down keys and an enter key (not shown) of the remote control transmitter 10.

[0023] A process of storing the schedule content input by the user using the remote control transmitter or the like in the memory 14 is performed.

[0024] When the user selects a schedule display item from a menu screen (not shown) using a remote control transmitter or the like, the schedule contents are read from the memory 14 and the personal schedule display screen is displayed on the screen by the OSD circuit 12. . Further, the system controller 13 includes a timer (not shown), and when the time set in the “notification date and time” on the individual setting screen of the personal schedule has come, or the notification setting on the basic setting screen of the personal schedule is designated. When the current time ("going out time" in the above example) is reached, the monitor 18 is turned on and the OSD circuit 12 displays the personal schedule display screen on the monitor screen. In addition, the personal schedule display screen can be automatically displayed several minutes before the leaving time, several hours before, the day before, etc. according to the designation of the user.

FIG. 3 shows an example of a personal schedule display screen.

In the example of the screen shown in FIG. 3A, the screen display of the program guide and the screen display of the user's schedule are simultaneously performed. The program table has a matrix display in which a time axis is arranged vertically and channels are arranged horizontally, and scrolling is possible in the vertical and horizontal directions. The user moves a cursor (not shown), puts the cursor on a cell of a desired program portion, and selects a program by performing a predetermined operation,
A reservation mode (viewing only, recording only, viewing + recording) can be determined. The personal schedule display screen can be used as a personal schedule input screen. That is, the user moves a cursor (not shown) to place the cursor on a cell in the personal schedule portion, and performs a predetermined operation to select the cell. If the selected cells are “13” and “14” on the time axis, “13:00 to 15:00” is automatically input as “date and time” in the individual setting of the personal schedule. Further, the action details can be input in the entry column on the right of the cell in the personal schedule portion.

In the screen example of FIG. 3B, the screen display of the program guide and the screen display of the user's schedule are simultaneously performed, and the program viewing unavailable time zone is determined based on the input scheduled date and time of the user's action. Then, the display mode of the program guide in the time zone is made different from the normal display. That is, when “Yes” is set in “Scheduled to go out” (see FIG. 2B), the system controller 13 determines that the time zone specified in “Date and time” is the program viewing unavailable time zone. Also, it is determined that the time zone from bedtime to wakeup or the time zone from going out to returning home in the basic setting of the personal schedule is a program viewing disabled time zone. Let the color be red. Thus, the user is alerted, and forgetting to reserve a program is reduced. Furthermore, in the reservation mode (viewing only, recording only, viewing + recording) when a predetermined program cell is selected, a guide for preferentially selecting “recording only” in consideration of the fact that the program cannot be viewed. Adopt the display.

In the screen example of FIG. 3C, the screen display of the program guide is not performed, but only the screen display of the user's schedule contents is performed. In this example, the number of schedules is displayed at the upper edge of the screen. Further, a "return" designation button and a "forward" designation button are prepared on the left side of the screen so that schedules other than the displayed schedule can be easily viewed.

[0029] When "viewing only" is set as the reservation mode, the power supply of the monitor 18 is automatically turned on at the program start time, the tuning process for program viewing is executed, and the program is displayed on the screen. Also, when “recording only” is set as the reservation mode, when the program start time comes, the VCR 16 is automatically turned on to execute tuning processing for program acquisition, and the received program is stored in the VCR 16. Supply and record. The control of the VCR 16 can be realized by using a remote controller (not shown) for an external device, or by sending a command to the VCR 16 through a control line connected to the VCR 16. When “viewing + recording” is set as the reservation mode, the above-described viewing processing and recording processing are executed.

[0030]

As described above, according to the present invention, a digital broadcast receiving apparatus can be used as a user's schedule management apparatus. That is, the user can view and input the user's own schedule with the same operation and feeling as viewing the program guide on the screen. In addition, if the configuration is such that the screen is automatically displayed when the information presentation date and time has arrived, the broadcast receiving device can reliably present the user's schedule even when the schedule presentation operation is neglected. become. Also,
If the screen display of the program guide and the screen display of the schedule are performed simultaneously, the user's action schedule and the program schedule can be directly compared and viewed, and processing such as program reservation corresponding to the action schedule can be performed. Is easier to do. In addition, if the configuration is such that the program viewing unavailable time zone is determined based on the input scheduled date and time of the user's action and the display mode of the program guide in the time zone is different from the normal display, the user's out-of-home time zone It is easier to focus on programs that are broadcast during non-program viewing hours such as sleep hours and bedtime, and it is also easier to determine the reservation type (viewing only, recording only, viewing + recording). It works.
