The present invention relates to a television receiver, and more particularly, to a method and apparatus for guiding channel variation information of a television receiver.

With the development of technology, television receivers have added various functions for convenient use. In particular, the AFT (Auto Fine Turing) function automatically detects the effective channel among 69 wireless channels and 125 wired channels and sets it as an effective channel.

This automatic tuning function is a patent application No. 10-1999-0004384 filed under the name "TV automatic channel search method", Patent Application No. 10-1999-0034770, filed as "TV channel automatic tuning method", Patent application No. 10-1998-0056614 filed as "TV channel automatic search method with a PIP function" has been disclosed.

However, since the effective channel varies depending on the date and time, the effective channel information set by the automatic tuning function in the first time period and the effective channel information set by the automatic tuning function in the second time period may be different from each other. For example, some television broadcast stations do not broadcast late-night broadcasts. Therefore, when the user sets an effective channel by using an automatic tuning function in the middle of the night, the channel used during the day at the transmitter station is set to an invalid channel.

As described above, despite the fact that the effective channel is variable, information about the channel is not guided to the user, so the user cannot operate the television receiver optimally.

In addition, as digital television broadcasting, in which a plurality of effective channels exist or disappear in a single channel, is widely used, it is more important to guide users of channel variation information.

Accordingly, an object of the present invention is to provide a channel variation information guiding method of a television receiver capable of guiding a user with channel variation information.

Another object of the present invention is to detect channel fluctuation information and guide the fluctuation information even when the user is editing a channel registered on the television receiver, thereby realizing channel fluctuation information in real time. In providing a method.

According to the present invention for achieving the above object, in the channel variation information guidance method of a television receiver having a plurality of first and second tuners, when a channel editing request occurs, the channel list tuned through the first tuner And displaying a channel edit screen on which preset effective channels are displayed, searching for valid channels by performing an autotuning function through the second tuner while displaying the channel edit screen, and using the second tuner. Searching for valid channels, if the searched valid channels and the preset valid channels through the first tuner are different from each other; and if the searched valid channels and the preset valid channels are different from each other, different channels are detected. It is characterized by including the step of guiding the user through the channel editing screen.
The channel editing function of the television set enables automatic channel setting to set an effective channel. Some of the set effective channels can be set as a favorite channel according to the user's selection. It also allows you to release the state.

Referring to FIG. 1, which shows a schematic configuration diagram of a television receiver having a channel editing function, the microcomputer 110 of the television receiver controls the television receiver as a whole, and according to a preferred embodiment of the present invention. In accordance with the present invention, the channel edit screen is displayed on the OSD, and the first and second tuners 120 and 122 are controlled to search whether the channel information has changed and to guide the user. The memory unit 112 stores various setting information and a processing program of the microcomputer 110. The user interface 114 interfaces between the user and the microcomputer 110, and a remote controller or a keypad is employed as the user interface 114.

The RF switch 118 provides broadcast signals received from the antenna 116 to the first and second tuners 120 and 122. The first and second tuners 10 and 122 tune to only the signals of a specific channel among the received broadcast signals under the control of the microcomputer 110 and provide them to the AV switch 124. The AV switch 124 provides signals output from the first and second tuners 120 and 122 to the first and second digital comb filters (126, 128) under the control of the microcomputer 110. The first and second DCFs 126 and 128 process the input signals and provide them to the first and second NTSC decoders 130 and 132, respectively. The first and second NTSC decoders 130 and 132 decode the input signals and provide them to the VCP 134. The VCP 134 processes the input signal and provides it to the display unit 136 and controls the deflection output unit 140 through the deflection controller 138.

A channel variation information guiding method according to a preferred embodiment of the present invention applicable to the television receiver described above will be described with reference to the flowchart shown in FIG.

When the user requests the channel editing from the microcomputer 110 through the user interface 114 (step 200), the microcomputer 110 displays the channel editing screen (step 204). Referring to FIG. 3, which shows the channel editing screen, 69 wireless channels and all 125 wired channels are displayed on the channel editing screen. Among the all channels, the effective channel detected through the auto tuning function and the channel selected by the user are distinguished from each other by changing the contrast or color. The preferred channel selected by the user is displayed in the favorite channel list. The user can switch channels using the direction key of the user interface 114, and the signal broadcast through the corresponding channel is displayed on the monitor window W whenever the user switches channels. Through the channel editing screen, the user can determine whether each channel is an effective channel, which program is broadcasted to each channel, and which channel is to be set as a favorite channel.

The microcomputer 110 displays an effective channel, a favorite channel, and the like on the channel edit screen, and outputs a signal received from a channel selected by the user to the monitor window W. FIG. At this time, the microcomputer 110 tunes a channel selected by the user using the first tuner 120.

In this way, while outputting a signal received through the channel selected by the user, the microcomputer 110 searches whether the user requests channel switching using the direction key of the user interface 112 (step 208). When the user requests channel switching, the microcomputer 110 outputs a signal received through the switched channel to the monitor window W. FIG. In this case, the microcomputer 110 tunes the AV signal received from the selected channel using the first tuner 120 (step 210).

While displaying the channel edit screen as described above, the microcomputer 110 performs an automatic tuning function using the second tuner 122 to search for valid channels (step 212).

Here, in the flowchart of FIG. 2, the microcomputer 110 may control the first tuner 120 and the second tuner 122 sequentially, but the microcomputer 110 may control the two tuners 120 and 122 at the same time. have. That is, the microcomputer 110 may control the first tuner 120 to tune a channel to be output to the monitor window W of the channel edit screen, and perform the automatic tuning function by using the second tuner 122. .

When the valid channel is searched through the auto-tuning function, the microcomputer 110 checks whether the found valid channel is different from the set valid channel in advance. If the two valid channels are different from each other, the microcomputer 110 displays the channel variation information on the channel editing screen (step 216). For example, as shown in FIG. 3, the microcomputer 110 displays the heart pattern shown on the left side of the channel for the newly searched channel, or the corresponding channel box for the channel found as the invalid channel but is found as an invalid channel. Dots can be displayed.

By displaying the channel variation information in this way, the user can easily check whether the channel is changed without checking all the channels during channel editing.

The microcomputer 110 continues the above steps 208 to 216 until the user completes the channel editing.

As described above, according to the present invention, the channel variation information is guided to the user, so that the user can grasp the state of each channel and edit the channel without directly checking the state of all channels while the user edits the channel.

Furthermore, the present invention has the advantage of rapidly reducing the number of channels to be checked when registering as a favorite channel when viewing only a valid channel when editing a channel in a general television where channel switching is very cumbersome.
