Abstract

A picture display apparatus has respective modes in which it displays at least three different types of pictures in sequence in response to actuations of a single switch. The picture display apparatus may be incorporated within a conventional television receiver having a programmable timer, and in such case the first type of picture is the normal television picture, the second type of picture is a display of the current day of the week and current time, and the third type of picture is a display of programming information stored in the programmable timer. When the switch is actuated within a predetermined time from the occurrence of a characteristic event in the respective mode, the next type of picture in the sequence is displayed. When the switch is actuated after the predetermined time has elapsed, the first type of picture in the sequence is displayed.

Claims

1. A picture display apparatus for displaying at least first, second and third types of pictures in that order in a repeating cyclical sequence, said picture display apparatus comprising;

display means having first, second and third modes of operation for displaying said first, second and third types of pictures, respectively;

actuable switch means;

control means operably connected to said display means and responsive to actuation of said switch means for establishing one of said modes of operation and thereby selecting the respective one of said types of pictures for display, each of said modes having a characteristic event occurring therein;

timing means for determining an elapsed time from said characteristic event occurring in the respective mode to a next actuation of said switch means;

said control means being responsive to an actuation of said switch means in each of said modes to select the next of said modes in said sequence when said elapsed time is 1ess than a predetermined time, and to select said first mode for displaying said first type of picture when the elapsed time is at least as great as said predetermined time.

2. A picture display apparatus according to claim 1;

wherein said first type of picture is a standard television picture;

said second type of picture is a display of a day of the week and a current time;

said control means includes programmable timer means for storing programming information corresponding to said television picture; and

said third type of picture is a display of said programming information.

3. A picture display apparatus according to claim 2;

wherein said second type of picture includes a first subpicture displaying said day of the week and said current time, and a second subpicture displaying said current time; and

wherein said first subpicture is displayed for said predetermined time following the selection of said second mode, and said second subpicture is displayed following said predetermined time after said selection of the second mode.

4. A picture display apparatus according to claim 1;

wherein said display means includes a standard television receiver having channel selection means for selecting one of a plurality of television channels to provide said first type of picture;

said control means further includes programmable timer means including memory means for storing channel reserve information adapted to be read out of said memory means for controlling said channel selection means to select reserved channels at reserved times;

said second type of picture is a display of a day of the week and a current time; and

said third type of picture is a display of said channel reserve information.

5. A picture display apparatus according to claim 4;

wherein said programmable timer means further includes clock means for generating day of the week information and current time information, and wherein said second type of picture is a display of said day of the week information and said current time information.

6. A picture display apparatus according to claim 5;

wherein said programmable timer means further controls said channel selecting means to prevent selection of blocked channels at blocked times in accordance with channel block information stored in said memory means and corresponding to said blocked channels and times; and

said picture display device selectively displays said channel block information as a fourth type of picture in a fourth of said modes.

7. A picture display apparatus according to claim 6;

further comprising a plurality of actuable key means for generating said channel block information and said channel reserve information; and

wherein said control means is responsive to actuation of said key means to store said generated channel reserve and channel block information in said memory means.

8. A picture display apparatus according to claim 7;

wherein actuation of said key means further generates initial day of the week and initial time information, and said clock means generates said day of the week information and said current time information in accordance with said initial day of the week information and initial time information generated by actuation of said key means.

9. A picture display apparatus according to claim 7;

wherein said characteristic event of the second mode is the actuation of said switch means to select said second mode for said display of the second type of picture.

10. A picture display apparatus according to claim 9;

wherein said control means stores said channel reserve information only in said third mode; and

wherein the characteristic event in said third mode is the later of the actuation of said switch means to select said third mode and the most recent actuation of one of said key means in said third mode.

11. A picture display apparatus according to claim 10;

wherein said control means stores said channel block information only in said fourth mode; and

wherein the characteristic event in said fourth mode is the later of the actuation of said switch means to select said fourth mode and the most recent actuation of one of said key means in said fourth mode.

12. A picture display apparatus according to claim 11;

wherein said fourth type of picture includes a first subpicture initially displayed upon entering the fourth mode for assisting the input of an identifying code to said memory means by actuation of said key means, and said control means stores said channel block information in said memory means in response to said identifying code.
