Abstract

PURPOSE:To automatically change-over a channel according to a program to be selected by storing the channel after change-over and the weekday and time thereof in a memory and reading the channel when the weekday and time become same to the data of the memory to change over the same. CONSTITUTION:A memory 4 stores the channel changed over by a channel change-over switch 2 and the data of a clock 5 at the time of a memory mode and becomes a data memory of a channel and a change-over time at the time of a reproduction mode. The clock 5 always transmits the data of a weekday and a time to a control circuit 3. By this constitution, when a channel is changed over during reception at the time of the memory mode by the switch 2, the channel after change-over and the weekday and time thereof are stored in the memory 4. When the same weekday and time as the data of the memory 4 are obtained during reception at the time of the reproduction mode, the channel data of that time is read and the channel of a tuner 6 is automatically changed over.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to an automatic channel switching device for use in televisions, radios, etc.

Conventional technologyWhen the power is turned on, conventional television, radio, etc. receiving devices
The channel is set to play when the power is off.

Further, in a receiving device equipped with a reservation timer, if the time and channel are set in advance, the power can be turned on at the specified time and the reserved channel can be received.

Problems to be Solved by the Invention In modern times, broadcast programs on television, radio, etc. are repeated on a weekly or monthly basis. Along with this, it is common for viewers to have a rhythm of selecting the same programs every week unless there are special programs.

However, with current receiving devices, you have to tune in every time according to the program, which is very troublesome, and even when a reservation timer is used, many people are unable to use it due to the inconvenient settings, and the power supply QN-OFF
Since it is linked to the alarm clock, it could only be used as a timer to set the alarm time.

In view of this, an object of the present invention is to provide a receiving device that automatically switches channels according to the program cycle selected by each user.

Means for Solving the Problems The present invention takes the following measures in order to achieve the above object.

(1) A mode changeover switch that changes between storage mode and playback mode, a channel changeover switch that allows the operator to select a channel, a memory, a clock,
When in memory mode, the tuner stores the changed channel and the 9 hours of the day of the week in memory, and in playback mode, when the 9 hours of the week match the data in the memory, the channel data in the memory is read out and the tuner's channel is stored. It is composed of a control circuit that performs switching.

) If you switch channels in a short period of time to search for a program while in memory mode, the memory will fill up quickly if you memorize all of these actions, so you may not be able to switch to another channel within a certain amount of time after switching channels. If the memory is canceled, the memory has a control circuit with an added function to cancel the memory.

@) Multiple storage sections are provided on the memory so that multiple people's program patterns can be stored.

(4) In order to identify which mode it is in, whose storage category it belongs to, and to check the remaining memory capacity, the mode and storage category can be displayed on both sides of the TV or with display elements such as dedicated LCDs or LED-strapping lamps. Display remaining memory.

For production The present invention has the following effects due to the above-described configuration.

(1) If the channel is switched using the channel changeover switch during reception in memory mode, the switched channel p, its day of the week, and time will be stored in the memory.
During reception in playback mode, when the day of the week and time matches the data in the memory, the channel data in the memory can be read out and the tuner channel can be switched automatically.

(Useful data in memory can be saved even when switching channels for a short time to search for a program.)

(Can store channel switching patterns for 31 or more people.

(4) The operating status of the equipment can be easily confirmed.

Example Embodiments of the present invention will be described below with reference to FIGS. 1 to 3.

FIG. 1 is an embodiment of a block diagram of an automatic channel switching receiving apparatus according to the present invention.

Reference numeral 1 denotes a mode changeover switch for switching between a storage mode, a playback mode, and a stop mode. Reference numeral 2 denotes a channel changeover switch, which is used by the operator to select a channel μ. Reference numeral 3 denotes a control circuit which, when the channel is selected by the tuner 6 or when the channel is switched by the channel switching operation panel 2 in memory mode, stores the switched channel, day of the week, and time in the memory 4; , in playback mode, memory 4
When the day of the week and time are the same as the data, the channel data at that time is read out and the channel of the tuner 6 is switched. Note that if you switch channels in a short period of time to search for a program while in memory mode, the memory will quickly become full if all these actions are memorized, so you will have to switch to another channel within a certain amount of time after switching channels. A function may be added to cancel the memory if the memory is deleted. Next, the memory 4 stores the channel and clock 6 data switched by the channel changeover switch 2 in the storage mode, and serves as a data memory of the channel and switching time in the playback mode. The clock 6 always sends day and time data to the control circuit 3. 6 is a tuner for selecting the receiving station.

With this configuration, when the channel is switched using the channel changeover switch 2 for a received signal in the storage mode, the switched channel, its day of the week, and time are stored in the memory 4, and during reception in the playback mode, When the same day of the week and time as the data in the memory 4 comes, the channel data for that time can be read out and the channel of the tuner 6 can be automatically switched. Therefore, if you select the program you want to watch in memory mode for one week, you can set it to playback mode from the next week and automatically switch programs over time even when the power is on or the receiving device is operating. can.

FIG. 2 shows an example of the stored contents of the memory 4 in FIG. 1 for one channel change.

Here, the day of the week is 3 bits because there are 7 days in a week, 1 bit for morning and afternoon, 4 bits for 12 hours, ebtt because 1 hour is 60 minutes, and setting the minimum switching operation to 16 seconds.
It is 2 bits because it is divided into 4 parts of 1 minute, and 4 bits when switching the 1e channel.

This is an example in which a total of 20 bits of memory space is set.

FIG. 3 is a memory map of the memory 4 shown in FIG. 1, and the time settings are stored in order of earliest setting. In addition, if new data is entered in the storage mode on the way, the control circuit 3
Using the data for 2 hours, 1 minute, and 1 second of the day of the week, the pigs in the memory are sorted in descending order of time setting.

Note that a plurality of storage sections may be provided on the memory so that the program payons of a plurality of people can be stored.

In addition, in order to identify which mode it is in, whose storage category it belongs to, and to check the remaining memory capacity, display elements such as TV screens, dedicated LCDs, LEDs, or lamps can be used to display the mode, storage category, and remaining memory capacity. It is preferable to display the information.

Effects of the Invention As described above, according to the present invention, even when channels are switched in a short period of time to search for a program, unnecessary data in the memory can be omitted, and multiple channel switching patterns can be stored. You can also,
It is possible to provide an automatic channel switching receiving device that allows easy confirmation of the operating status of equipment.
