Description

TV auto search method

The present invention relates to a television, and more particularly, to a channel automatic search method of a television that helps a viewer to easily select a channel by sequentially receiving and displaying regular channels when the television is first turned on.

In general, when the television is powered on, it is set to the channel that was set last before it was last turned off, and the program being broadcast on that channel is displayed on the television screen.

As such, when a viewer first powers on the television, the viewer must first watch the channel set on the television, without the choice of channel. Then, by manipulating the remote control or the switch in the television set, the user had to up / down the channel to see what program was playing on the other channel.

That is, even if a viewer checks which program is currently being broadcast in a newspaper or magazine, the viewer turns on the TV for the first time and confirms that the final channel when the TV is set off on the TV appears on the screen. There was an inconvenience of changing the desired channel using the up / down keys or the numeric keys on the operation panel of the television.

In addition, when information about programs and channels that are currently being broadcasted through newspapers or magazines cannot be known, viewers can change the channels using the remote control or the keys of the television and check the programs that are broadcast on all rectified channels. It was inconvenient to memorize the channel where the desired program is aired and change the reception channel.

The present invention has been made to solve the above-mentioned conventional inconveniences, the purpose is to display all the selected channels in order for a certain time when the power of the TV is increased so that viewers can see what programs are currently being aired And it is to provide a channel automatic search method of the TV that facilitates the viewer's channel selection.

As a means for achieving the object of the present invention as described above, the present invention is a control means having an on-screen display function, tuning means for pre-receiving a channel according to the international language of the control means, and receiving by the tuning means A channel automatic search method for a television set comprising: a detection means for detecting a channel signal, and an image chroma processing means for displaying an image by the detection means and a character or icon by the control means on a CRT;

An environment setting step of setting conditions such as channels to be searched, a first appearing channel, and a broadcast time allocated to each channel and whether or not to perform automatic search;

Checking whether to automatically search channels according to a condition set in the configuration step when the power is turned on;

If the channel is set to be automatically searched in the checking step, tuning the corresponding channels in order for a time set by the environment setting means; and if the channel is set to not be automatically searched, tuning the channel set before power-off;

After all the display for the channel set by the above step is completed, the channel selection key input is checked and the receiving channel is set to the input selection channel.

Hereinafter, with reference to the accompanying drawings will be described in detail the operation of the present invention.

4 is a block diagram showing an internal basic configuration of a television set to which the channel automatic search method according to the present invention is applied. 41 is a tuner unit for tune-in to and receiving an arbitrary channel using an antenna in an airwave mixed with a plurality of channel signals. 42 is a detector for detecting a channel signal received by the tuner unit 41 at baseband and outputting a broadcast signal, and 43 is a broadcast signal detected by the detector 42 and a microcomputer 44. The image chroma processing unit for chroma processing to display the character or icon signal from the CRT on the CRT, 44 has an on-screen display function, and the image chroma processing unit ( 43) is a microcomputer to control the tuning operation of the tuner unit 41, 45 is a character or icon data or channel automatic search destination A memory for storing algorithms, etc., is stored in the memory, and 46 is a remote controller that is provided with a numeric key and a plurality of function buttons to send a command and a selection signal to the microcomputer 44.

FIG. 1 is a flowchart showing a channel automatic search method according to an embodiment of the present invention, and describes an embodiment of the present invention shown in FIG. 1 based on the configuration of FIG.

If the television is powered on (101), the control unit (i.e., the microcomputer 44) in the television set checks 102 to reset the environment. In this case, when the environment is reset, the environment is changed to the environment setting mode instead of the search mode to set the environment that is a reference for channel automatic search. It is to set the stone channels and the display time of each channel (103).

Then, it is checked whether auto-search is turned on or off (104). The determination is based on the environment set in step 103 and checks whether automatic search is turned on or off at the time of setting the environment.

Thus, if the auto-discovery channel is set to ON, the preset channels are sequentially tuned for the set time, so that a program broadcasted in a plurality of channels is shown for a predetermined time (105). So when all the selected channels are shown (in other words, all set channels are shown and back to the initial selection channel), it is checked if there is a channel selection (106). In other words, the microcomputer 46 checks whether the channel selection signal is applied from the remote controller 46. Accordingly, when the viewer presses the desired channel number, the microcomputer 46 recognizes this and transmits an international language signal to the tuner unit 41. The tuner unit 41 receives the channel selected by the viewer. The channel signal is output to the CRT through the detector 42 and the image chroma processor 43.

If the channel auto search is turned off in the determination step 104, the microcomputer 44 does not operate in the channel auto search mode showing several channels in sequence, and simply receives and outputs all channels set before power off.

2 is a flowchart showing a channel automatic search method according to another embodiment of the present invention, and the initial operation is the same as in the embodiment shown in FIG. The operation of another embodiment of the present invention shown in FIG. 2 will be described based on the configuration of FIG. 4 described above.

That is, if the television is turned on (201), the control unit (i.e., the microcomputer 44) in the television set checks whether or not to reset the environment (202). In this case, when the environment is reset, the environment is changed to the environment setting mode instead of the search mode to set the environment that is a reference for channel automatic search. It is to set the channels to be displayed and the display time of each channel (203).

Next, it is checked whether auto-search is turned on or off (204). The determination is based on the environment set in step 203 and checks whether automatic search is turned on or off at the time of setting the environment.

If the auto search is set to the above, first, the signal of the initial selection channel is received and displayed on the CRT (205), and after the set time passes, it is checked whether the stop key is input (206), and if not, the selection is made. After changing the channel to the next channel signal (207), the selected channel is received and displayed on the CRT (205). Then, it is checked again whether a stop key has been input (206). Thus, until the stop key is input, the microcomputer 44 receives while changing the channels set as the auto search channels. The viewer watches the channel change output by this automatic search process and presses the stop key on the channel when the desired program appears.

Finally, when the stop key is input, the currently selected channel is set as the television's receive channel (208).

In the step 204 of checking whether the automatic search is turned on, if the automatic search is turned off, the viewer does not want the automatic search, and thus the channel set before the power-off is tuned to the receiving channel. It is shown on a television brown tube.

3 (a) to 3 (f) are exemplary diagrams for explaining a method of setting an environment in the above-described embodiment, and when the viewer manipulates the menu key or the on-screen display key of the remote controller 46, FIG. ), Icons or letters representing the predetermined modes or functions, respectively, appear in place of the image. Then, the viewer selects an auto search icon or text indicating an auto search mode by operating a direction key or a numeric key of the remote controller 46.

Then, the automatic search setting mode screen appears as shown in FIG. 3 (b). In this embodiment, the setting items are shown in the form of a bar. In addition, in the present embodiment, four setting items are shown. First, the initial search channel starts when the automatic search is started, and the search time setting, which is the viewing time allocated to each selected channel, and the channel to be searched. These are the auto search on / off setting indicating whether or not auto search is performed. These are various changes and applications that can be made.

If the initial search channel is set among the above settings, parentheses appear next to the initial search channel setting bar as shown in FIG. The viewer simply puts the desired channel number (eg, number 7) in the parenthesis. The channel number (i.e., 7) set here is the channel that appears first during automatic channel search.

When the search time setting items are selected, parentheses for inputting time appear next to the search time setting bar as shown in FIG. 3 (d). As described above, the viewer inputs a desired time (unit is seconds) as a number. In this embodiment, it is set to 5 seconds.

When the on channel setting item is selected, parentheses for inputting channels appear next to the on channel setting bar as shown in FIG. 3 (e), and the viewer inputs channels to be searched in the parentheses. In the present embodiment, numbers 7, 9 and 11 are set.

Also, when the auto search on / off item is selected, as shown in FIG. 3 (f), a letter 'on' or a letter 'off' appears with parentheses next to the auto search on / off bar. If you press the random setting key once when 'On' appears, it changes to 'Off' and if it is 'Off', it changes to 'On'. Here, 'off' means that you do not want auto search, and 'on' means you want auto search. In this embodiment, it is set to 'on'.

When the environment is set as described above, when automatic search is started, first, channel 7 is tuned in and a program airing on channel 7 appears for 5 seconds on the CRT. Channel 9 is then tuned in and shows the program being broadcast on channel 9 for 5 seconds, then changed back to channel 11 and the program is being broadcast on channel 11 for 5 seconds. Therefore, in the embodiment of the present invention, as described above, if all of the programs of channels 7, 9, and 11 appear for 5 seconds, after viewing all of them, a desired channel may be input, and in another embodiment of the present invention, If the desired program appears while the program on the channel is playing, press the stop key (or a key set to another selection key).

As described above, when the TV is turned on, the present invention is not fixed to one channel but is automatically changed to show a plurality of set channels in order so that a user can directly check a program that is broadcast on multiple channels. The effect is to facilitate channel selection.
