Abstract

PURPOSE:To allow a television receiver to display a set channel automatically at the arrival of a reserved time by reserving a date and time and a channel to be watched for the television receiver in advance. CONSTITUTION:A remote controller 1 of a television receiver is in use to designate a date and time and a channel to be watched in advance and they are written in a storage section 7 via a control section 11. When a time designated by a discrimination section 6 comes, a program of a designated channel is displayed on a display section 19, then the consecutive watch is entered by the remote controller 1. When the consecutive watching is not inputted, a switch of a power supply section 5 is turned off after the lapse of a prescribed time under the control of a power supply control section 4. When the designated time comes when the television receiver is switched on, since a designated program in terms of picture-in-picture is displayed on the display section 19 via a small pattern generating circuit 16, whether the picture is watched as it is, or a master pattern and a slave pattern are replaced together or only the master pattern is watched is selected by the remote controller 1. When the designated time by reservation comes, the power supply of the television receiver is switched off based on the control of the control section 4.

[0008] In the above configuration, a method and operation for specifying in advance the date and time and channel for receiving images on the television receiver using the remote control 1 or the keyboard of the input unit 2 will be described. 22 is a reservation data table set in the data storage area of the storage unit 7, and the data to be reserved is stored in the remote control 1.
(or keyboard) to input. First, a reservation mode is set in the control section 11 using the input section 2. With this setting, a storage area as shown in FIG. 2 is read out from the storage unit 7 and displayed on the screen. After that, for example, February 3rd, start time 10:15, end time 10:3
If you enter channels 0 and 1, “0” will appear in the address field 23.
01" is written, "2 and 3" are written in the month and day field 24, "10:15" is written in the start time field 25, and "1" is written in the end time field 26.
0:30'' are respectively written via the control unit 11, and “1” is written in the channel column 27. For the second reservation, February 3rd, start time 13:00, end time 13:00
:30, 6 channel, as shown in the second line of Figure 2, "002, 2 and 3, 13:000, 13:30
, 6'' is written in the storage area. In this way, the third and subsequent reservations are sequentially written and reserved. Reservations do not have to be entered in order of newest date and time; new reservations are written at the end.

[0009] Subsequently, the control unit 11 searches the reservation data table 12 in the storage unit 7 in accordance with the date change in the clock unit 3.
Sort the reservation data for that day in order of read time. For example, on February 3rd, 10:15, 10:30, 13
:00, 13:30. Then, the smallest time data is set in one of the comparison circuits of the discrimination section 6 and compared with the time data from the clock section 3. First, data of 10:15 is set to one side of the comparator circuit, and from time to time the clock section 3
The control unit 11 checks the power switch of the television power supply unit 5 based on the matching signal from the comparison circuit. As shown in the flowchart of Figure 3, step (
(hereinafter referred to as ST) 1 determines whether it is the reserved time, and if no, the same routine is repeated. If yes, proceed to ST2 and determine whether the power switch is on; if yes, proceed to ST2.
Proceed to step 3 to "select the second tuner", that is, switch the second tuner section 12 to the reserved channel "1". The television receiver is turned on and displays the video (main screen) selected by the first tuner section 13. Control unit 11 in ST4
switches the video switching section 20 to display the video selected by the second tuner section 12 on the display section 19 instead of the video selected by the first tuner section 13. The control unit 11 generates a character pattern for “return the screen to its original state” from the character pattern storage unit 8, generates it in the character pattern generation unit 10, and sends it to the image synthesis unit 17.
to merge it onto the main screen. At ST5, "Do you want to restore the screen?"
If it is YES, input YES from the remote control unit 1. If NO is input, proceed to ST9.

[0010] Television reception starts at 10:15 on a designated channel, and then the time data on one side of the comparator circuit is changed to 10:30 in the next order. ST9
In order to determine whether the power switch is off, the determination unit 6 compares it with the time data from the clock unit 3 in the same manner as described above.
When the time data reaches 10:30, the determination in ST9 becomes YES, and if the data match, matching data is output. ST
10 controls the power supply control section 4 to turn off the power switch of the television power supply section 5. Further, the time data of the comparison circuit of the determination unit 6 is changed to the next data of 13:00. At the same time, the matching data changes the data string of the reservation data table 22 to 1.
Scroll up the line and update the reservation data table 22.

[0011] If NO in ST2, the process proceeds to ST12. S
At T12, "select the second tuner", that is, the control section 11 switches the second tuner section 12 to the reserved channel "1". In ST13, the control section 11 controls the power supply control section 4 to turn on the power switch of the television power supply section 5. Control unit 11
generates the character pattern "Do you want to continue watching TV?" from the character pattern storage section 8, and the character pattern generation section 1
0 and is synthesized on the main screen by the image synthesis section 17. ST1
4, it is determined whether "Do you want to continue watching TV?", and if the answer is yes, input "yes" from remote control 1. The process then proceeds to ST9 and enters the flow of ST9. If no one is near the TV receiver, for example, it will automatically determine NO after a few minutes, proceed to ST10, turn off the power switch, and finish (S
T11).

On the other hand, the reserved channel can also be displayed on the display section 19 in a picture-in-picture manner. In that case,
ST4, 5, and 6 in the flowchart shown in FIG.
Replaces T7, 8, 9, 15 and 16. In ST7, the video signal selected by the second tuner section 12 is converted into a sub-screen by the small screen creation circuit 16, and then sent from the image synthesis section 17 to the first
The image is synthesized on the main screen of the video amplifying section A14 and displayed on the display section 19. The control unit 11 generates a character pattern “Do you want to switch between parent and child screen?” from the character pattern storage unit 8, generates it in the character pattern generation unit 10, and generates it in the image synthesis unit 17.
to merge it onto the main screen. In ST8, it is determined whether to switch between the parent and child screens, and if the answer is YES, input YES from the remote controller 1. If NO is input, proceed to ST15. In ST6, the control unit 11 switches between the first and second tuners and swaps the parent and child screens. The control section 11 generates a character pattern "Do you want to make the screen only the main screen?" from the character pattern storage section 8, generates it in the character pattern generation section 10, and combines it with the main screen in the image composition section 17. In ST15, it is determined whether to make the screen the main screen, and if the answer is YES, input YES from the remote controller 1. If NO is input, proceed to ST15. In ST16, the control section 11 turns off the second tuner and cancels the composition of the child screen from the image composition section 17. Only the main screen is displayed on the TV receiver.

In the above description, a video message is displayed to the operator and the operator performs the determination operation, but it is also possible to display a voice message or an audio and video message to perform the determination operation.

[0014]

As described above, according to the present invention, it is possible to reserve a desired program to a television receiver in advance in a simple manner, so that a desired program will not be missed. Also, even if you cannot do it manually, the program you want to watch can be automatically switched as desired, which is very effective.
