Description

[Detailed description of the invention] Industrial applications The present invention relates to a channel selection device for a television receiver.

Conventional technologyAs television receivers in general become more personalized,
The user's lifestyle is often reflected in how they are used. For example, watching a certain program at a certain time on a certain day of the week becomes a pattern. On the other hand, this pattern seems to be relatively common even in the case of family use.

Conventionally, when the power switch is turned on, the channel selection is normally the same as when the power switch was previously turned off. An example of its configuration is shown in FIG. In the figure, during normal use after the power is turned on, the selector switch 8 transmits an external channel selection instruction from the operation unit 7 to the microcomputer 1, and the microcomputer 1 gives the channel selection data to the china 2 and stores the data in the last channel memory 9. Always writing. When the power is turned on, data in the memory 9 is switched by the switch 8 and transmitted to the microcomputer 1 according to instructions from the power-on detection section 10.
The station that was just before the power was turned off is always selected.

Furthermore, a method has been proposed as a prior art in which a program is reserved in advance for a specific program on a specific day of the week and at a specific time. An example of its configuration is shown in FIG. In the figure, in normal use, the selector switch 8 transmits an external tuning instruction from the operation unit 7 to the microcomputer 1, and the microcomputer 1 provides tuning data to the tuner 2, but during automatic tuning, the input unit 12 inputs the day of the week.
time. Programs for reserving stations, etc. are sequentially read out from the memory 11 by the timer 3, and the tuning instructions are switched by the selector switch 8 and transmitted to the microcomputer 1.
Tuning will be automatically performed as scheduled.

PROBLEMS TO BE SOLVED BY THE INVENTION When trying to watch on such a conventional television receiver, when the power switch is turned on, the channel selection is usually the same as when the power switch was previously turned off. However, since this is often different from what the user wants to watch, the user usually immediately performs a channel selection operation to switch to the program he or she wants to watch. To explain it in a concrete situation, for example, when you come home (let's say it's a fixed time A), you watch channel B and turn off the power switch, and when you turn on the power switch in the morning (let's say it's time C), it becomes channel B, so Sometimes it's a hassle to select the D channel you want to watch.

It is also common for people to miss a program they would normally watch while watching another program. Therefore, a system has been proposed as a prior art in which a program is reserved in advance for a specific program on a specific day of the week and at a specific time, but the user must input the day of the week, time, and channel by some means. The problem was that it was difficult to use.

The present invention solves the above problems and aims to provide an automatic channel selection device that does not require program reservations in advance.

Means for Solving the Problems In order to achieve the above object, the present invention provides a tuning system in which a tuner performs tuning operation based on tuning data from a microcomputer, in which data from a timer unit that counts days and hours of the week is used as a variable. a calculation section that calculates and totals the channel selection data; a memory section that stores the contents; a processing section that generates a channel selection command from the data in the memory section in response to data from the timer section; The control unit is comprised of an operating section that performs an external channel selection operation by issuing a signal, and a changeover switch section that switches between a channel selection command from the processing section and a channel selection command from the operating section.

Effect of the Invention With the above configuration, the microcomputer normally outputs channel selection data and selects a channel in response to a channel selection command from the operating section, but the data at that time is totaled based on time data from the timer section. In other words, the timer section measures the day of the week in units of one week and time in units of 24 hours and minutes, and the calculation section measures the day of the week in units of one week and the time in units of 24 hours and minutes.
Tuning data at a specific time is aggregated and stored in a memory unit. The processing section switches the changeover switch to the processing section when the result of the most frequently selected channel selection data in the past at that time exceeds a certain level of frequency in response to the data in the timer section, and also tells the microcomputer to Issues a tuning command to select the most popular channel selection data in the past, that is, the program.

EXAMPLE Hereinafter, an example of the present invention will be described with reference to FIG. As shown in FIG. 1, in a tuning system in which a tuner 2 performs tuning operations based on tuning data from a microcomputer 1, a timer unit 3 that counts the day of the week and time
A calculation section 4 that calculates and totals the channel selection data using data from the timer section 3 as a variable, a memory section 5 that stores the contents, and a processing section 6 that generates a channel selection command from the memory section 5 based on the data from the timer section 3. , an operation section 7 that issues a channel selection command to the microcomputer to perform a channel selection operation, and a changeover switch section 8 that switches between a channel selection command from the processing section 6 and a channel selection command from the operation section 7.
Consists of. To explain the operation of the above configuration, normally the microcomputer 1 outputs channel selection data and selects a channel in response to a channel selection command from the operation section 7, and the data at that time is totaled based on the timer section 3. That is, the timer unit 3 measures the date in units of one week and the time in units of 24 hours, and the calculation unit 4 totals the channel selection data on a specific day of the week and at a specific time and stores it in the memory unit 5.

The processing section 6 switches the changeover switch 8 to the processing section 6 when the total result of the most frequently selected channel selection data in the past at that time exceeds a certain level of frequency according to the timer section 3, and also tells the microcomputer 1 to display the past selection data at that time. A channel selection command is issued to select the most popular channel selection data, that is, the program.

As described above, according to the automatic channel selection device of the embodiment of the present invention, the channel selection data is aggregated in the memory along with the time data, and the most frequently selected channel is automatically selected, thereby eliminating the need for presetting. On a specific day of the week and at a specific time, a predetermined channel is automatically selected without a channel selection command from the operation panel.

Effects of the Invention As is clear from the above embodiments, the present invention aggregates channel selection data and timer data in a memory, and automatically selects the most frequently selected channel. When you turn on the TV receiver, it will automatically tune in to the channel you often watch at that time, or the program you usually watch at a certain time, without having to go through the complicated process of pre-setting it according to the time. It has the effect of automatically selecting a channel so that you will not miss it, and is extremely useful as an invention that takes the lifestyle of a television set one step further.
