Description

TV channel selector and method {CHANNEL SELECTING APPARATUS AND METHOD FOR TELEVISION}

The present invention relates to a TV broadcast reception technology, and more particularly, to a TV channel selection apparatus and method for quickly selecting a desired channel when receiving a digital broadcast.

In general, TV will be included among the representative inventions of modern civilization. That's because it's faster, more versatile, and easier to use than any other medium for delivering information. That's why most homes and offices have TVs and are already becoming an essential tool in the information age. to be.

Moreover, in recent years, as digital TV broadcasting using cable TV or satellite is started, the number of channels that can receive at least tens to hundreds or more has been increased, so that the user can directly receive information that is unilaterally delivered by the broadcaster. You can choose the information you want to watch.

Accordingly, when the number of channels is several, as in the prior art, as shown in FIG. 1, the channel can be easily moved to a desired channel by pressing the 'channel increase' or 'channel decrease' key (1) of the remote control remote controller. In order to move to a desired channel by the above-mentioned method, there was a problem of continuously pressing the channel increase / decrease key or moving the stored channel number by directly pressing the numeric key (2).

Accordingly, an object of the present invention is to provide a TV channel selecting apparatus and method for quickly and easily moving to a desired channel.

Figure 1 is an exemplary view showing the configuration of a conventional general remote control.

10: channel easy moving unit 20: channel increase and decrease

30: microcomputer 40: infrared light emitting unit

The present invention for achieving the above object is a simple channel moving unit for moving a large number of channels in a short time with a small movement; A channel increasing / decreasing unit for increasing or decreasing channels at predetermined channel intervals; It is achieved by including a microcomputer for performing various control operations for switching the channel of the TV by receiving the channel signal from the channel simple moving unit and the channel increasing and decreasing unit, which is attached to one embodiment according to the present invention. When described in detail with reference to the drawings as follows.

First, Figure 2 is a block diagram showing the configuration of the channel selection apparatus of the present invention TV, as shown in the channel simple moving unit 10 for moving a large number of channels in a short time with a small movement; A channel increase and decrease unit 20 for increasing and decreasing channels at predetermined channel intervals; The microcomputer 30 receives a channel signal from the channel simple moving unit 10 and the channel increasing / decreasing unit 20 and performs various control operations for switching channels of the TV.

Here, the infrared light emitting unit 40, which has not been described, is a means for switching the channel by transmitting the channel signal coded by the microcomputer 30 to the TV in the infrared form.

Then, the operation process and the effect of the embodiment according to the present invention configured as described above are as follows.

First, as shown in FIG. 3A or FIG. 3B, the simple channel moving unit 10 can move many channels in proportion to the distance or the rotational amount even if only a slight movement is performed by a finger manipulation. If the user approaches the desired channel to some extent by operating (10), the channel increase / decrease unit 20 is operated to finely move one channel or two channels to finally move to the desired channel.

However, when the channel simple moving unit 10 is configured in the form of a slide switch as shown in FIG. 3A, the distance that can be moved to the left and the right is limited. In the case of the rotary switch, as shown in FIG. 3B, the left and right sides of the rotary switch can be rotated without a predetermined limit, thereby generating a channel signal by adding the relative amount of rotation rotated in the current channel.

In addition, the channel increase / decrease unit 20 is to move to an approximate channel by manipulating the channel simple moving unit 10 and then finely moves by one channel. A type of switch constituting the simple channel moving unit 10 is provided. It is desirable to configure in a position that can be easily fine-tuned according to.

Next, a process of outputting the channel signal in the channel selection device configured as described above will be described in more detail with reference to the flowchart of FIG. 4.

For example, if a user who is currently watching channel 4 wants to watch channel 114 but does not know the correct channel number, first, the user simply adjusts the channel easy moving unit 10 to quickly move to a nearby channel. Let's do it.

Accordingly, the microcomputer 30 detects the movement position or the rotation amount of the channel simple moving unit 10 and increases or decreases the number of channels (for example, 4) in the current channel (for example, 4) in proportion to the converted amount. For example, 107 may be calculated.

Next, the channel is moved to the new channel number 111 by adding the channel number 107 calculated as described above to the current channel number 4.

Accordingly, the user can operate the channel increase / decrease unit 20 to increase the channel by one channel and finally move to the desired channel number 114.

In this case, the channel increased or decreased by the channel increase / decrease unit 20 may be increased or decreased by one channel or by predetermined units.

As described above, the TV channel selection apparatus and method of the present invention have an effect of quickly and easily moving a desired channel in a TV that can watch a plurality of channels such as digital broadcasting.
