Abstract

PURPOSE:To make unnecessary a troublesome channel selecting operation by automatically setting a channel based on the information stored in the memory at the time of turning on a switch. CONSTITUTION:The title device provides a key input part 2 to input the day of the week, time, exchange number, etc., of the program (channel selecting information) to be set beforehand, a timer 3 to output the present day of the week and time to a control part 1 and output the interrupting signal at a prescribed time interval and a memory (RAM) 4 to store the station selecting information such as the day of the week, time, exchange number, etc., of the program inputted by the key input part 2 as a corresponding table. At the time of turning on the power source, a channel is set based on the signal from the memory 4. Thus, for the person to view the same program at the same time zone every week, the probability that the desired channel can be automatically selected at the time of turning on the power source can be increased.

Description

Detailed Description of the Invention (Industrial Field of Application) The present invention provides an automatic tuning function for a television receiver that makes it possible to easily tune in to a desired program in a broadcast receiving device for a television receiver. Regarding equipment.

(Prior Art) When changing the station to be received in the broadcast receiving device a of a television receiver, it is common practice to manually change the channel dial of the receiver or by remote control.

In addition, in recent electronic switching TV receivers, etc., when the power switch is turned ON, the channel selection circuit is reset and a specific station is selected, or the station that was selected the last time the power switch was turned OFF. Generally, the configuration is such that stations are selected as they are.

Additionally, TV Kasa viewers tend to watch a specific program at the same time on the same day of the week every week, but this is not the case with the traditional channel selection method described in 1.

- "If the channel when the U power source is turned on is not the desired one, it is always necessary to select the channel by paging, which is troublesome. This problem also applies to the 4A radio receiver.

(Object of the Invention) The present invention has been made in view of the above, and aims to eliminate the troublesome tuning operation of conventional TV receivers as much as possible,
An object of the present invention is to provide an automatic channel selection device such as a television receiver that increases the probability that a desired channel will be automatically selected when the power is turned on through a simple procedure.

(Summary of the Invention) In order to achieve the above object, an automatic channel selection device 6 for a television receiver according to the present invention includes a control section that performs calculations based on input information and outputs a predetermined control signal to a tuner, and a control section that is registered in advance. A key input unit for inputting the 11th day and 1st time of the program you want to keep and the station number, and a timer for outputting the current day of the week and time to the control unit and outputting an interrupt signal at predetermined time intervals. , a memory device (6) for storing 11M1 day, time 1 station numbers of programs inputted by the key input unit as a correspondence table, and a channel is set based on a signal from the memory device when the power is turned on. Ru.

(Example) Below, an automatic channel selection device for a television receiver according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a block diagram of the apparatus θ of the present invention, and FIG. 2 is a flowchart showing the procedure for channel selection.

In FIG. 1, reference numeral 1 indicates a CI that performs calculations based on various input information and outputs a predetermined control signal to the tuner.
etc., 2 is the day of the week 1 of the program you want to set in advance
A key input section for inputting time, station number, etc. (channel selection information), 3 is the current 1■1'', a key input section for outputting the time to the control section 1 and outputting an interrupt signal at predetermined time intervals. A timer 4 is a storage device v1 (RAM) that stores channel selection information such as the day of the week, time, and station number of the program inputted by the key input unit 2 as a correspondence table. Note that SW is a power switch that turns on and off the power supply to the control unit 1.

FIG. 2 is a flowchart showing the tuning procedure by the tuning circuit having the above-mentioned configuration, and one proposition of this flow is that a correspondence table must be created by the key input section 2. is stored in the storage device 4 in correspondence with the station number of each desired program, the day of the week, and the time of broadcast. By turning on the power switch of the television receiver, the control unit 1 stores the correspondence in the storage device 4. Step S21: Search the table for a program (station number) that will be broadcast at a time corresponding to the current time (or in a time zone close to the current time).
), output the obtained station number to the tuner (step 5
22).

In this manner, when the power switch is turned on, a preprogrammed channel is selected.

Changing the channel selection program is performed via the control unit 1 by operating the key input unit 2 in the same manner as the setting operation,
The station number and IW1 time corresponding to each program are stored in the storage device 4.
will be registered.

Next, in the first embodiment, the program to be automatically selected was set and changed by key input, but it is also possible to have a control unit with a learning function do this for you.
) Noh. That is, by memorizing the channel selection operation by one person, the time at which it was performed, and the time each time a program is selected, a correspondence table for one week is created and automatically stored in the storage device 14. Control may be performed such that the program is registered in advance, and if a program different from the previously registered program is selected in each time slot when the power switch is turned on, the program is updated sequentially.

Furthermore, the frequency of channel selection may be taken into consideration as a condition for the update, that is, the registered station number for the time period may be updated only when a certain program is viewed multiple times in a row.

In this way, it is possible to eliminate the inconvenience of having the registered station number updated when the user happens to watch a different program than usual only in a certain week. Such a learning function and a setting method using key input are compatible, and it is configured such that it is possible to selectively realize either one of the modes or a mode that combines both modes using a changeover switch, etc. can do.

Next, store the correspondence table of the time, day 11, and station number -F on a magnetic card or IC card, and keep this in each person's 1+j. ・Also, install a reading device on the TV receiver side. By doing so, it is possible to perform a channel selection operation according to each individual's preference. That is, by attaching cards with different contents for each individual to the reading device of the same television receiver, it is possible to automatically select programs of one's preference, regardless of programs registered by other people, which is convenient. It is.

Note that the present invention is effective for channel selection in radio receivers as well as television receivers.

(Effects of the invention) As described above, according to the automatic channel selection device for a television receiver of the present invention, for people who watch the same program at the same time every week, the desired channel is automatically selected when the power is turned on. By increasing the probability of being able to tune in, you can eliminate as much troublesome tuning operations as possible and prevent yourself from missing a single program.11
can do.
