Further, a part of the output signal of the video detection circuit 14 is sent to the audio detection circuit 20, where the audio signal is detected and the audio signal is extracted. The volume level of the audio signal is adjusted by the volume adjustment circuit 21, sent to the audio amplification circuit 22, and output via the speaker 23.

A key input unit 24 is connected to the control unit 19. The key input unit 24 is provided with TV operation keys such as a tuning key, a volume adjustment key, a brightness adjustment key, and a power switch, and a calendar display key for designating a calendar display mode for calendar control, for example, A previous month key (forward key) for displaying a calendar, a next month key (reverse key) for displaying a calendar for the next month, and the like are provided.

Further, a remote control signal sent from a remote control (remote control) transmitter (not shown) is input to the control unit 19 via a remote control signal light receiving unit 25 and a remote control signal receiving unit 26. Like the key input unit 24, the remote control transmitter includes a television operation key, a calendar display key for specifying a calendar display mode for calendar control, a previous month key (forward key) for displaying a previous month's calendar, A next month key (reverse key) for displaying a calendar of the next month is provided.

The control unit 19 controls the television receiving system according to a signal from the key input unit 24 or a remote control transmitter. Further, the control unit 19 has a calendar function, and stores calendars for a plurality of years in a calendar memory (not shown).
When the calendar display key of the remote controller 4 or the remote control transmitter is operated, the mode is switched from the television display mode to the calendar display mode, and the calendar information for the current month or a specified month is read from the calendar memory and output to the display drive circuit 16. The display drive circuit 16 outputs the image signal from the chroma signal processing circuit 15 to the display unit 17 in the television display mode, but when the calendar display mode is designated, the calendar information sent from the control unit 19 is output. Is output to the display unit 17 and displayed. Further, when the previous month key or the next month key is operated in the calendar display mode, the control unit 19 reads the calendar of the corresponding month from the calendar memory in accordance with the key operation, and outputs the calendar to the display drive circuit 16, It is displayed on the display unit 17.

Hereinafter, the details of the calendar display processing in the control unit 19 will be described with reference to the flowchart of FIG. In the television display mode, the control unit 19 outputs the image signal output from the chroma signal processing circuit 15 to the display driving circuit 16.
Through the display unit 17 to display the television reception signal on the screen. When the calendar display key is operated in this state, the control unit 19 switches from the television display mode to the calendar display mode, reads out the calendar information of the current month from the calendar memory, outputs it to the display drive circuit 16, and outputs it to the display unit 17. indicate. In this state, as shown in the flowchart of FIG. 2, the operation waits for the next month key and the previous month key, and when the next month key and the previous month key are operated, the calendar is fast-forwarded according to the key operation. .

That is, when the calendar display mode is designated and the calendar of the current month is displayed on the screen, the control section 19 performs a key scan (key scan) for the previous month key and the next month key in step A1 of FIG. 2 as shown in FIG. Scan), and at the timing of the key scan, step A2
The following processing is performed. The control unit 19 determines in steps A2 and A
In 3, the key scan detects the scan timing when the key is pressed as A, the scan timing when the key is kept pressed as B, and the scan timing when the key is not pressed as C. . The scan timing period (t) is set to, for example, one second.

In step A2, the state of the next month key is determined. If the key state is A (when the key is pressed), the flow advances to step A4 to display the next month's calendar, and the key state is B.
If (when the key is kept pressed), the flow advances to step A5 to determine whether or not the displayed month is "January", that is, whether or not the year has been switched. If the displayed month is not January, the process proceeds to step A4 to display the calendar of the next month. If the displayed month is January, the process proceeds to step A6 and the calendar of January of the next year of the displayed year is displayed. Is displayed. That is, when the next month key is sequentially operated one by one, the calendar of the next month is displayed every month by the processing of step A4 every time the key operation is performed.

If the next month key is operated continuously, the process proceeds from step A5 to step A4 until the displayed month reaches January, and the calendar for the next month is displayed at intervals of the key scan, ie, one month at a time, ie, at the key scan interval. Is updated and displayed at one second intervals. When the displayed month reaches January, that is, when the year is switched, the process proceeds from step A5 to step A6, and the calendar for January of the next year is sequentially updated and displayed at one second intervals. FIGS. 4A to 4F show examples of calendar display when the next month key is continuously operated. Assuming that the next month key is continuously operated while the calendar of "October 1989" is displayed as shown in FIG.
As shown in (c) and (d), the calendar for the next month is updated and displayed every second every month. Then, when the calendar “January 1990” is displayed in FIG.
That is, when the year is switched, this state is detected in step A5, and thereafter, by the processing in step A6, as shown in FIGS.
In this case, "January 1991", "January 1992"
Is updated and displayed at one-second intervals.

Therefore, when it is desired to view the calendar several years ahead, the next month key is continuously operated to fast-forward the calendar, and when the calendar of the desired year (January) is displayed, a hand is temporarily operated from the next month key. Release and operate the next month key again. At this time, the next month key is depressed once or continuously, and a calendar of a desired month is displayed on the screen. As described above, the calendar of the desired year and the desired month can be promptly displayed.

For example, when the calendar of "September 1999" is displayed ten years ahead while the calendar of "September 1989" is displayed, it is assumed that one month of fast-forwarding is performed for one month.
Suppose you spend seconds, "October → November 1989 →
"December → January 1990" sent "4 seconds", then
"January 1991 → January 1992 →,…, → 1999
"January" sent to "9 seconds", and February 1999 → 19
March 1999 →,…, → September 1999
Seconds ”, the total is“ 4 + 9 + 8 = 21 seconds ”.
Since calling the same calendar conventionally takes "120 seconds", the fast-forward processing can be significantly improved.

On the other hand, when the previous month key is operated, the state of the next month key is determined to be C (when not pressed) in step A2, and the flow advances to step A3. In this step A3, the state of the previous month key is determined, and
If (when the key is pressed), the flow proceeds to step A7 to display the calendar of the previous month. If the key state is B (when the key is kept pressed), the flow proceeds to step A8 and the displayed month is displayed. It is determined whether or not it is “December”, that is, whether or not the year is switched. If the displayed month is not December, proceed to step A7 and display the calendar of the previous month. If the displayed month is December, proceed to step A9 and display the calendar of December of the previous year of the displayed year. I do. That is,
If the previous month keys are operated sequentially one by one, step A
By the process of 7, the calendar of the month before one month is sequentially displayed according to the key operation.

When the previous month key is continuously operated, the process proceeds from step A8 to step A9 until the displayed month reaches December, and the calendar of the previous month is sequentially displayed.
When the month being displayed is December, that is, when there is a drop in the year, the process proceeds from step A8 to step A9, and the calendar of December of the previous year is sequentially updated and displayed at one-second intervals. FIGS. 5A to 5F show examples of calendar display when the previous month key is continuously operated. Assuming that the previous month key is continuously operated while the calendar of "March 1989" is displayed as shown in FIG.
As shown in FIGS. 8B, 8C, and 8D, the calendar for the month preceding by one month is updated and displayed at one-second intervals. And
In FIG. 9D, when the calendar of "December 1988" is displayed, this state is detected in step A8,
Thereafter, by the processing of step A9, FIGS.
As shown in the figure, the calendars for the December of the previous year are sequentially displayed.

In the operation of the previous month key as well, the fast forward of the calendar can be efficiently performed as in the case of the next month key. Then, in the calendar display mode, by operating a reset key or the like, the display returns to the normal television display mode.

In the above embodiment, the case where the calendar is displayed on the screen in units of one month has been described. However, the calendar may be displayed on the screen in units of two months. In this case, by operating the next month key and the previous month key, the calendar of the next month and the previous month not displayed on the screen is called up and displayed on the screen.

In the above embodiment, the calendar year is described as from January to December. However, any other month, such as from April to March of the next year, is set as the month for switching the year. Can be done.

Further, in the above-described embodiment, the case where the present invention is applied to a television receiver is described. However, if the present invention is provided with a display screen capable of displaying a calendar, such as a Japanese word processor, the above-described embodiment will be described. It can be implemented in a similar manner.
