Description

TV channel switching

The present invention relates to a television (hereinafter, referred to as a TV), and in particular, a channel frequently watched by a user is stored in a memory for each day of the week and a time zone, and the channel currently stored in the corresponding day and time is stored in the memory. It relates to a channel switching method of the TV to be automatically switched to.

In general, TV broadcasting refers to a TV and TV program (audio and audio signals) transmitted from a TV station through an antenna of a TV, and separates a video signal, a synchronization signal, and an audio signal in a TV receiver, respectively. To reproduce the video and audio signals.

With the development of communication technology these days, there are various TV broadcasts. When you see these kinds of TV broadcasts, satellite TV broadcasts that transmit and receive TV broadcasts through satellites, and broadcast programs transmitted by each cable station through cables are transmitted and received. Can be classified into cable broadcasting and TV broadcasting of the airwave transmission method which is most widely used. However, even if the TV broadcasting method is different from each other, the TV receiver can be used in common. In addition, due to the development of electronic technology, the TV receiver can be easily adjusted by the consumer, that is, the TV receiver with various functions added to the taste of the consumer is widely used.

Such a TV system has a channel automatic setting function for automatically searching and setting broadcast channels transmitted from each broadcasting station. That is, the channel automatic setting function is selected by the user using the channel selection key attached to the remote control or the main body to turn on the TV and select a desired channel. In this case, the user does not have to select the desired broadcasting channel. The channel setting function is called auto channel search function. Hereinafter, a channel automatic setting method of a TV according to the prior art will be described with reference to the accompanying drawings.

FIG. 1 is a schematic block diagram of a system of a general TV. Referring to FIG. 1, a configuration of a key input unit 11 for providing a channel automatic setting key input signal and a key input unit 11 may be provided. A tuner 10 for sequentially tuning frequencies in which a broadcast signal provided by each broadcasting station is received according to a tuning control signal according to a channel automatic setting signal provided, and controlling the whole of the TV system, and tuning to the tuner 10. TV system control unit 12 for providing a control signal, OSD (On Screen Display) unit 13 for text display, and selection broadcast signal output from tuner 10 under control of TV system control unit 12. And a display unit 15 for displaying a video signal output from the TV image signal processing unit 14 to the outside.

In this case, the TV system controller 12 automatically tunes a channel in the tuner 10 to sequentially set broadcast channels in which a broadcast signal is received in an internal memory. Therefore, when the user selects a channel selection key, that is, a channel up / down key, in order to select a channel, the channels are sequentially tuned according to the channel set in the memory.

A channel automatic setting method of a TV according to the related art using such a device will be described with reference to FIGS. 1 and 2. 2 is a flowchart illustrating an operation of a channel automatic setting method of a TV according to the prior art.

First, the user turns on the power of the TV by using the power key of the key input unit 11 (S101), and then determines whether a channel automatic setting key signal for automatic channel setting is input (S102).

As a result of determination, when the channel automatic setting key signal is input, the TV system control unit 12 scans the frequencies in the tuner 10 in a predetermined frequency step so as to tune the corresponding channel corresponding to the frequency at which the broadcast signal is received (S103). ).

That is, it is determined whether a broadcast signal is received at one frequency during scanning (S104), and channels corresponding to the frequency at which the broadcast signal is received are set in a memory in the TV system controller 12 (S105).

When the user selects the channel key (up / down key) of the key input unit 11 while setting the channels for receiving each broadcast signal, the user selects the channels in the order of the set channels. For example, suppose the channel tuning is set to 5, 6, 7, 9, and 11 channels. If the user presses the channel up key in the 5 channel state, the channel is tuned to 6 channels immediately. If you press the up key on 7 channels, you will be tuned to 9 channels instead of 8 channels.

However, after the automatic channel setting as described above, if the user wants to watch during TV viewing, that is, the time of frequently watching a program is aired, the user can switch to the corresponding channel using the channel switching key and watch the corresponding program one by one. There is this.

Accordingly, the present invention has been made to solve the above-mentioned problems according to the prior art, an object of the present invention is to memorize a channel frequently watched by the user day and time by the day and time, the channel is currently tuned It is to provide a channel switching method of the TV to automatically switch to the channel stored in the memory.

The channel switching method of the TV according to the present invention for achieving the above object is a channel switching method of a TV with a memory, the memory period for storing the channel selected by the user for each day or time zone Steps; If the memory period is set, sequentially storing the tuned channel and the tuned channel in the memory on each day and each day during the set period; Comparing the current day and the current time with one channel tuning time of a plurality of channel tuning times of the same day as the current day of the week stored in the memory when the set memory period elapses; Determining whether the currently tuned channels are the same as the channels tuned at the corresponding time stored in the memory when the comparison results match; In the case of the same channel, the currently tuned channel is kept as it is, and in the case of different channels, the channel is automatically switched to the channel stored in the memory.

Hereinafter, a channel switching method of a TV according to the present invention will be described with reference to the accompanying drawings.

3 is a flowchart illustrating an operation of a channel switching method of a TV according to the present invention.

First, in order to perform the automatic channel switching function, a memory period for storing the channels selected by the user at the day, time, and corresponding time is set (S101). That is, the memory period can be set to 1 day, 1 week or 1 month. In the memory period setting, when the memory period setting key of the key input unit 11 shown in FIG. 1 is selected, the TV system controller 12 processes the pre-programmed memory period setting screen through the OSD unit 13 and then OSD. On the display unit 15, one day, one week, one month --- is displayed in the form. Accordingly, the user may set the desired memory period using the key input unit 11 by looking at the displayed memory period setting screen.

Here, the case in which the memory periods are selected as one day and one week will be described.

When the memory period is selected as one day (S102), the channel selected by the user and the selected time for one day are sequentially stored in the memory (S103). For example, when the user selects channel 6 for the first time, channel 6 saves the selected time and channel 6 at the same time. After watching channel 6, the channel is switched to another channel after a certain time has elapsed. This will save the time the channel was switched and the channel that was switched.

In this way, it is determined whether the set memory period is reached while storing time and channel for one day (S104). Here, the determination of whether the memory period has elapsed may be accomplished by counting the time from the set time of the memory period and determining whether 24 hours have elapsed.

As a result of the determination, when the user turns on the TV power to watch TV after the memory period has elapsed, the current time is continuously compared with the times stored in the memory (S105).

As a result of the comparison, after determining whether the current time matches one of the times stored in the memory (S106), when the current time matches the one stored in the memory, it corresponds to the currently tuned channel and the time stored in the memory. The channels are compared with each other whether the channels are the same (S107).

As a result of comparison, when the channels are the same, the currently tuned channels are maintained (S109). When the channels are different from each other, the channels are automatically switched to the channels stored in the memory (S108). That is, since the channel is selected and watched by the user one day ago at the present time, the channel is automatically switched because the user is likely to select and watch the channel on the same day. If the user wants to watch a broadcast program broadcasted in another channel on the same day while the channel is switched, the other channel can be selected using the channel selection key.

On the other hand, a case where the memory period is set to one week will be described.

First, when the memory period is set to one week in step S110, it starts to sequentially store the channels selected by the user for each day of the week and time zone for each day in the order of day, time and channel (S111). .

Subsequently, it is determined whether the set memory period, that is, one week, has elapsed while storing the channel selected for each day of the week and the time of day for one week. Here, the determination of whether the memory period has elapsed determines the progress of the day of the week by counting the time from the set time of the memory period and counting each 24 hours, and thus determining whether one week has elapsed according to the progress of each day of the week. Will be done.

As a result of the determination, after the memory period, that is, one week has elapsed, when the user turns on the TV power to watch TV, the current day and time are compared with the day and time stored in the memory from then on (S113). ).

As a result of the comparison, after determining whether the current day and time are consistent with the day and time stored in the memory (S114), if the day and time of the current day and time are matched, the currently tuned channel and the day of the week stored in the memory are determined. And whether the channels selected and stored by the user at the time are the same channels with each other (S107).

As a result of the comparison, when the channels are the same, the currently tuned channels are maintained (S109). When the channels are different from each other, the channels are automatically switched to the channels stored in the memory (S108). That is, since the channel is selected and watched on the same day as the current day of the week one week ago at the current time, the user may select and watch the channel on the same day, so the channel is automatically switched. When the user wants to watch a broadcast program broadcasted in another channel while the channel is switched, the other channel may be selected using the channel selection key.

The memory period can also be set to one month. Even when the memory period is set to one month, the channel can be automatically switched in the same manner as described above, and the memory period can be set arbitrarily.

As a result, the present invention is to memorize the channel, time and day of the week to watch a lot for a certain period of time set by the user to automatically switch the channel currently tuned to the memory channel when the day and time.

As described above, the channel switching method of the TV according to the present invention stores a channel, a time and a day of the week that are frequently watched for a predetermined period of time set by the user, and automatically selects a channel currently tuned into the memorized channel when the corresponding day and time comes. By switching to, the convenience of channel selection that the user does not have to select a channel by using the channel switching key is increased.
