The present invention relates to a remote control capable of adjusting the channel search speed and / or volume level through the touch pad screen, and more particularly, to search for a channel at the speed desired by the user through the touch pad screen, and also to the speed and level desired by the user The present invention relates to a remote control capable of adjusting a channel search speed and / or a volume level to increase or decrease the volume level.

In recent years, a television (TV), which is an image medium for delivering predetermined image information to a user, provides various contents and attracts many people to his user.

On the other hand, in addition to a method of receiving predetermined video information from a broadcasting station, many people use a VCR which stores video information on a magnetic tape and can view it when a user desires.

At present, digital television combining the advantages of the television and the VCR is spreading. Unlike a VCR that stores video signals on a magnetic tape, the digital television has a new concept of a digital recorder that is stored on a hard disk, and a hard disk drive (HDD) is built into a set-top box or a TV main body. It is a next generation recording device that can record broadcast programs.

The digital television records information on a hard disk and reproduces the data using a file reproducing method such as a PC.

The digital television includes a memory chip (ROM) containing an operating system (OS) and playback software, a large-capacity hard disk, and a central processing unit (CPU) for playback.

The digital television is not much different from the conventional video cassette recorder (VCR) in that the basic function of storing and viewing the program transmitted from the broadcasting station is. However, since the digital television uses hard disks without writing tapes, there is no need for tape management and it is easy to find or edit a desired part.

In addition, the digital television can be connected to a telephone line to receive the latest broadcast schedule from time to time and utilize it for reservation recording. The reservation recording procedure is simple enough to select a broadcast list on the screen. You can record multiple programs at the same time, stop live broadcasts instantly, or repeat playback from seconds to minutes ago.

In addition, it supports the replay function by default, and it is possible to listen to interactive broadcasts in connection with broadcast service companies.

Therefore, such a digital television requires a variety of control operations for the user, and thus there are many complicated key operations.

1 is an explanatory view showing a conventional remote control.

As shown in FIG. 1, the conventional remote controller is provided with a number button and a menu button. In order to correspond to various control operations of the digital television, it is necessary to press the menu button several times to set a function.

In particular, one of the common functions used in the remote control is the channel search and volume control. This is probably one of the most used features in regular television as well as digital television.

In particular, as the number of channels is diversified due to the increase in cable stations and broadcasters, users cannot know the contents of all channels, and thus users have to search all channels in comparing and selecting broadcasts.

However, even when you want to see all the channels through channel change (channel search function), you must always hold down the channel up / down keys while circulating all channels, especially the speed for channel change is set by default on TV. It was not something the user could adjust arbitrarily.

In addition, the existing volume change method increases or decreases the volume at regular intervals, for example, it is cumbersome to continuously press and hold down the volume down key even if the volume is rapidly decreased at the current volume level. On the contrary, if the user wants to sharply increase the volume at the current volume level, there is a hassle of waiting for a predetermined time while continuously pressing the volume up key.

On the other hand, Figure 2 is an explanatory diagram showing a remote control having a conventional touch pad screen, the conventional remote control 100 having a touch pad screen 101 is a touch signal generated by the contact with the user on one side Pad screen 101 and the button portion 102 is provided with a plurality of buttons on the other side.

The touch pad screen 101 receives a touch signal by a touch by a user's finger or a stylus.

The button unit 102 includes a plurality of numeric buttons 103 and a basic menu button 104. Among these, the main menu button 104 includes a 'POWER' button for power on / off, a 'MENU' button for changing to the touch pad mode, a 'CHANNEL' button for easily changing channels, and a volume control. There is a 'VOLUME' button.

However, there is a remote controller having a touch pad screen as shown in FIG. 2, or a remote controller having a 'CHANNEL' button and a 'VOLUME' button on the touch pad screen 101. Even if you want to see all the channels through the channel change (channel search function), you should always hold down the channel up / down keys while circulating all the channels, especially the speed for channel change is set by default on the TV. It was not something the user could adjust arbitrarily.

In addition, when the volume is changed, the volume is increased or decreased at regular intervals, for example, even if the volume is suddenly decreased at the current volume level, it is cumbersome to continuously hold down the volume down key for a certain time, and on the contrary, If you want to sharply increase the volume at the level, there is still the hassle of having to hold down the volume up key for a while.

The present invention has been proposed to solve the above problems, the touch pad screen is provided with a channel navigation and / or volume control keys, through which the user can navigate the channel at the desired speed, and also the volume at the desired speed and level It is an object of the present invention to provide a remote control capable of adjusting the channel search speed and / or volume level to easily increase or decrease the level.

3A is an explanatory diagram illustrating a communication method between a remote controller and a television (TV) to which the present invention is applied, and illustrates a method of controlling the television (TV) 200 using the remote controller 100.

In FIG. 3A, the remote control 100 includes an infrared transceiver 105 and the television (TV) 200 includes a remote control transceiver 214 so that the television (200) 200 is connected to the infrared transmitter of the remote controller 100. The infrared ray control signal for controlling the television (TV) 200 is output to the remote control receiver of the control unit. At this time, the television (TV) 200 that receives the infrared control signal output from the infrared transmitter of the remote controller 100 operates by changing an on / off state, a channel state, a volume state, etc. according to the infrared control signal. Then, the television (TV) 200 transmits the operation state of the TV to the infrared receiver of the remote control 100 through the remote control transmitter, and the operating state of the TV through the touch panel screen of the remote control 100 (in the present invention) And volume level status).

Looking at the configuration of the television (TV) 200 with reference to Figure 3b, the television receiver used in the present invention is a tuner 201 for tuning a plurality of broadcast channels received through a different frequency band from a plurality of broadcasting stations And a demodulator 202 for demodulating the composite video signal received through the tuner 201, and for converting the analog composite video signal demodulated by the demodulator 202 into a digital composite video signal. A / D converter 203, a signal separator (DEMUX) 204, and a signal separator 204 for separating the digital composite video signal converted by the A / D converter 203 into an audio signal and a video signal. A decoder 205 for decoding the audio signal and the video signal separated by the "), a speaker 206 for outputting the audio signal to the outside, and an audio signal decoded by the decoder 205 to the speaker 206. Make a proper electrical signal And an amplifier 208 for amplifying and outputting an electrical signal output from the audio processor 207 to the speaker 206.

The television receiver includes a screen 209 for displaying a video signal, a video processor 210 for converting the video signal decoded by the decoder 205 into a signal form suitable for the screen 209, various kinds of information and A storage unit 211 for storing an execution program, a remote control transmitter / receiver 212 for communicating with the remote controller 100 through an infrared communication method, and control reception and output of a composite video signal, and a remote controller 100 According to a user command (channel search speed and volume level control command) input through a tuner, the tuner 201 searches for a channel at a desired channel search speed (tuning speed) among broadcasts broadcasted by each cable TV station and broadcaster. Control unit 213 for controlling the increase and decrease of the volume level to a level desired by the user through the amplifier 208 and the video signal output from the video processor 210 on the screen 209. And an image processing unit 212 for output.

The tuner 201 receives a plurality of broadcast channels received through different frequency bands from a plurality of broadcast stations (including cable TV stations, broadcasters, etc.), and the tuner 201 tunes and tunes the broadcast channels instructing reception. The analog composite video signal received through the broadcast channel is transmitted to the demodulator 202. At this time, the controller 213 increases or decreases the channel by changing the channel search speed (tuning speed) by controlling the tuner 201 when a 'channel search speed adjustment command' is input from the user through the remote controller 100.

Here, the 'channel search speed control command', when the pointer indicating the current channel is dragged from the remote controller 100, the channel search speed (tuning speed) is changed according to the dragged distance (movement distance). It is a control signal of the remote controller 100 for the TV 200 to increase or decrease the channel according to the dragged direction so that the channel can be searched (once the channel is increased or decreased, it is increased or decreased in one direction until it returns to the current channel). Repeat). This will be described in more detail below.

The demodulator 202 receives the composite video signal modulated and transmitted from the broadcasting station through the tuner 201 and demodulates the modulated composite video signal and outputs the demodulated composite video signal to the A / D converter 203.

The A / D converter 203 samples the analog composite video signal input from the demodulator 202 under the control of the controller 213 and converts the analog composite video signal into a digital composite video signal, and then converts the digital composite video signal into the signal separation unit 204. Will output

The signal separator 204 separates the digital composite video signal input from the A / D converter 203 into an audio signal and a video signal under the control of the controller 213 and outputs it to the decoder 205.

The decoder 205 decodes the audio signal and the video signal input from the signal separation unit 204 under the control of the controller 213, decompresses the compressed audio signal and the video signal, and then decodes the decoded audio signal. The video signal is output to the video processor 210 and output to the video processor 210.

The audio processor 207 converts an audio signal input from the decoder 205 into an electric audio signal suitable for the speaker 206 under the control of the controller 213 and outputs the audio signal to the amplifier 208. At this time, when the 'volume level control command' is input from the user through the remote controller 100, the controller 213 controls the amplifier 208 to increase or decrease the volume by varying the volume control speed.

Here, the 'volume level adjustment command', when the pointer indicating the current volume level is dragged on the remote controller 100, recognizes the dragged point to increase or decrease the volume level, and at this time, adjusts the volume according to the dragged speed. The control signal of the remote control 100 for the TV 200 to adjust quickly or slow. This will be described in more detail below.

The screen 209 outputs an image output from the image processor 212.

The video processor 210 converts a digital video signal input from the decoder 205 into a signal suitable for the screen 209 under the control of the controller 213 and outputs the signal to the video processor 212.

The storage unit 211 is a storage medium for storing various types of information, and may be implemented as a memory device such as RAM or EEPROM or a hard disk driver (HDD). In 211, an execution program for controlling the reception and output of the composite video signal is set, and algorithms for channel search, volume control, and the like are stored.

The control unit 213 controls the tuner 201 under the instruction of the remote controller 100 to output the video signal of the tuned broadcast through the screen 209 (that is, change the channel search speed (tuning speed) to change the channel). Channel search by increasing or decreasing) and controlling the amplifier 208 to output an audio signal of the tuned broadcast through the speaker 206 (that is, maintaining the volume level and volume control speed desired by the user). ).

Herein, the instructions of the remote controller 100 include a channel search speed control command and a volume level control command, and the channel search speed control command controls the remote control 100 for the TV 200. As a signal, when the pointer indicating the current channel is dragged by the remote controller 100, the channel search speed (tuning speed) is changed according to the dragged distance (movement distance), and the channel is increased according to the dragged direction. Or to reduce the channel search. At this time, once the channel is increased or decreased in one direction, the channel is repeated until it returns to the current channel.

In addition, the 'volume level control command' is a control signal of the remote controller 100 for the TV 200. When the pointer indicating the current volume level is dragged from the remote controller 100, the drag point is recognized. You can increase or decrease the volume level and adjust the volume quickly or slowly depending on the dragged speed.

The image processor 212 outputs an image signal output from the video processor 210 on the screen 209 under the control of the controller 213.

Then, with reference to Figure 4 will be described with respect to the remote control capable of adjusting the channel search speed and volume level through the touch pad screen.

First, the remote controller 100 according to the present invention reveals not only the channel search speed control function or the volume level control function through the touch pad screen but also the channel search speed control function and the volume level control function at the same time.

Remote control 100 according to the present invention has a touch pad screen 401 as shown in Figure 5a, in order to perform two functions (channel search speed adjustment function, volume level adjustment function) at the same time, touch pad screen 401 is divided into a channel manipulation sensor region 501 on the upper side and a volume manipulation sensor region 502 on the lower side. However, the present invention is not limited thereto, and the channel manipulation sensor region 501 may be configured to appear on the left side, and the volume manipulation sensor region 502 may appear on the right side. It is obvious that it is possible to change the area.

Meanwhile, when only one function (channel search speed control function or volume level control function) is performed, only one region 501 or 502 appears on the touch pad screen 401.

For convenience of explanation, hereinafter, a method of simultaneously performing two functions (channel search speed adjusting function and volume level adjusting function) will be described.

As shown in FIG. 4, the remote control capable of adjusting the channel search speed and volume level through the touch pad screen 401 according to the present invention detects a touch input and indicates a current channel and volume level of the TV 200. A touch pad screen 401 displaying first and second pointers, a first input unit 402 for detecting a drag direction and a distance of the first pointer (current channel), and a second pointer (current volume) A second input unit 403 for detecting a drag speed and a point of a level) and a display control signal for displaying the first and second pointers on the touch pad screen 401, and the first input unit 402. A display control unit 406 for recognizing the drag direction and the distance by the control panel, the drag speed and the point by the second input unit 403, and outputting a channel search speed control signal and a volume level control signal, and a touch according to the display control signal. Pad First and second drivers 404 and 405 for outputting the first and second pointers to the lean 401, a receiver 409 for receiving and outputting the first and second pointer signals from the TV 200, and a display controller. Outputs a transmission control signal for controlling the channel search speed and volume level control signal 406 to be transmitted to the TV 200, receives the first and second pointer signals output from the receiver 409, and displays the display control unit 406. And a transmitter 408 for transmitting the channel search speed control signal and the volume level control signal to the TV 200 according to the transmission control signal of the controller 407.

The channel search speed control signal is different from the channel search speed (tuning speed) according to the dragged distance (movement distance) when the pointer (which is the first pointer) indicating the current channel is dragged by the remote controller 100. In this case, the channel search is performed by increasing (for example, when the drag direction is in the right direction or upward direction) or decreasing (for example, when the drag direction is in the left direction or the down direction) according to the dragged direction. It is a control signal of the remote control 100 for the TV 200. At this time, once the channel is increased or decreased in one direction, the channel is repeated until it returns to the current channel. As the dragged distance (movement distance) increases, the search is performed while increasing or decreasing the channel at a faster speed (shorter time to stay in each channel). On the contrary, the smaller the dragged distance (moving distance) is, the longer the time stayed in each channel is.

In addition, when the pointer indicating the current volume level (which is the second pointer) is dragged by the remote controller 100, the volume level control signal recognizes the dragged point and increases the volume level (eg, the drag point). If it is in the right or up direction) or decrease (for example, if the drag point is in the left or down direction), the volume is adjusted quickly or slowly depending on the dragged speed. In other words, as the drag speed is faster, the volume is increased or decreased at a higher speed. On the contrary, as the drag speed is slow, the volume is slowly increased or decreased.

6A to 6C, the process of adjusting the channel search speed through the touch pad screen 401 in the remote controller 100 according to the present invention will be described.

As described above, the touch pad screen 401 is divided into a channel manipulation sensor region 501 on the upper side and a volume manipulation sensor region 502 on the lower side, but is not limited thereto, and the channel manipulation sensor region 501 on the left side. The volume manipulation sensor region 502 can be configured to appear on the right side, and it has been suggested that the regions shown on the upper side and the lower side can be changed, or the regions shown on the left side and the right side can be changed.

Accordingly, the first pointer 503 indicating the current channel located in each of the regions 501 and 502 can also be moved left and right (FIGS. 6A to 6C) or can be moved up and down (not shown), and the increase / decrease direction is arbitrarily set. It is possible.

For example, assuming that the channel is 1 to 100 and the current channel is 11, the first pointer 503 indicating the current channel is the channel manipulation sensor region 501 as shown in FIG. 6A. It is located in the center of.

In the state of FIG. 6A, when the user drags the first pointer 503 positioned in the center of the channel manipulation sensor region 501 to the last right part of the channel manipulation sensor region 501 as shown in FIG. The input unit 402 detects the drag direction (right side) and the distance (moving distance) and informs the display controller 406, and the display controller 406 recognizes this and the fastest speed that the TV 200 supports according to the drag distance. And outputs the channel search speed control signal to increase the channel.

On the other hand, in the state of FIG. 6A, although not shown in the figure, if the user drags the first pointer 503 located in the center of the channel manipulation sensor region 501 to the last left part of the channel manipulation sensor region 501. The first input unit 402 detects the drag direction (left) and the distance (moving distance) and informs the display control unit 406, and the display control unit 406 recognizes this and supports the TV 200 according to the drag distance. Outputs a channel search speed control signal that allows the channel to be searched by increasing the slowest speed.

Meanwhile, in the state of FIG. 6A, when the user drags the first pointer 503 positioned in the center of the channel manipulation sensor region 501 to the right in the channel manipulation sensor region 501 very finely, as shown in FIG. 6C. The first input unit 402 detects the drag direction (right side) and the distance (moving distance) and informs the display control unit 406, and the display control unit 406 recognizes this and increases the channel every 5 seconds according to the drag distance. And outputs the channel search speed control signal for searching.

The output channel search speed control signal (channel increase and decrease and the dwell time for each channel) is transmitted to the TV 200 through the control unit 407, and the TV 200 varies the dwell time for each channel according to the channel search speed control signal. (Short or long) to increase or decrease the channel to perform channel search (tuning).

Then, the process of adjusting the volume level through the touch pad screen 401 in the remote control 100 according to the present invention with reference to Figures 7a to 7e.

As described above, the touch pad screen 401 is divided into a channel manipulation sensor region 501 on the upper side and a volume manipulation sensor region 502 on the lower side, but is not limited thereto, and the channel manipulation sensor region 501 on the left side. The volume manipulation sensor region 502 can be configured to appear on the right side, and it has been suggested that the regions shown on the upper side and the lower side can be changed, or the regions shown on the left side and the right side can be changed.

Accordingly, the second pointer 504 indicating the current volume level located in each of the regions 501 and 502 can also be moved left and right (Figs. 7A to 7E) or can be moved up and down (not shown), and the increase / decrease direction is arbitrarily Can be set.

For example, assuming that the volume level is from 1 to 100, and assuming that the current volume level is 30, the second pointer 504 indicating the current volume level may be a volume manipulation sensor region (as shown in FIG. 7A). 502).

In the state of FIG. 7A (current volume level 30), as shown in FIG. 7B, the user places the second pointer 504 located at the center of the volume manipulation sensor region 502 at the right end of the volume manipulation sensor region 502. FIG. When dragging fast to, the second input unit 403 detects the drag point (right side) and the speed (moving time) and informs the display controller 406, and the display controller 406 recognizes this and then rapidly increases the speed according to the drag speed. A volume level control signal is outputted to increase the volume level to 100. At this time, if the drag speed is slow, the volume increase is slow.

On the contrary, in the state of FIG. 7A (current volume level 30), as shown in FIG. 7C, the user places a second pointer 504 positioned at the center of the volume manipulation sensor region 502 to the left of the volume manipulation sensor region 502. When dragging to the last part quickly, the second input unit 403 detects the drag point (left side) and the speed (moving time) and informs the display controller 406, and the display controller 406 recognizes the drag point and increases the speed according to the drag speed. The volume level control signal is output to reduce the volume level to zero at a speed. At this time, if the drag speed is slow, the volume decreases slowly.

As such, the faster the dragging speed, the volume increases or decreases at a higher speed. On the contrary, the slower dragging speed increases or decreases the volume.

On the other hand, assuming that the volume level is 1 to 100 times and assuming that the current volume level is 30, a second pointer 504 indicating the current volume level is shown in FIG. 7A as shown in FIG. 7A. When positioned at the center, the left side of the volume manipulation sensor region 502 is centered on the second pointer 504 and is the volume 0 to 30 region, and the right side of the volume manipulation sensor region 502 is centered on the second pointer 504. Becomes the volume range 30-100.

Thus, in the state of FIG. 7A (current volume level 30), as shown in FIG. 7D, the user moves the second pointer 504 located in the center of the volume manipulation sensor region 502 to the volume manipulation sensor region 502. When dragging to the right middle part quickly, the second input unit 403 detects the drag point (right side) and the speed (movement time) and informs the display controller 406, and the display controller 406 recognizes the drag point according to the drag speed. The volume level control signal is output to increase the volume level to 65 at a high speed. At this time, if the drag speed is slow, the volume increase is slow.

Conversely, although not shown in the figure, in the state of FIG. 7A (current volume level 30), the user places a second pointer 504 located at the center of the volume manipulation sensor region 502 to the left of the volume manipulation sensor region 502. When dragging to the middle part quickly, the second input unit 403 detects the drag point (right side) and the speed (moving time) and informs the display controller 406, and the display controller 406 recognizes the drag point and increases the speed according to the drag speed. The volume level control signal is output to reduce the volume level to 15 at a speed. At this time, if the drag speed is slow, the volume decreases slowly.

As shown in FIG. 7D, when the current volume level is 65, the second pointer 504 indicating the current volume level 65 is positioned at the center of the volume manipulation sensor region 502, and the volume manipulation centers on the second pointer 504. The left side of the sensor region 502 is a volume 0 to 65 region, and the right side of the volume manipulation sensor region 502 is a volume 65 to 100 region around the second pointer 504.

Therefore, as shown in FIG. 7E, in the state where the current volume level is 65, the user places the second pointer 504 located in the center of the volume manipulation sensor region 502 at the first left part of the volume manipulation sensor region 502. When dragging fast to, the second input unit 403 detects the drag point (right side) and the speed (moving time) and informs the display controller 406, and the display controller 406 recognizes this and then rapidly increases the speed according to the drag speed. A volume level control signal is output to reduce the volume level to 10. At this time, if the drag speed is slow, the volume decreases slowly.

As such, when the volume level is adjusted, the volume is changed by recognizing the dragged point, not the principle of constantly increasing or decreasing.

The present invention described above is capable of various substitutions, modifications, and changes without departing from the technical spirit of the present invention for those skilled in the art to which the present invention pertains. It is not limited by the drawings.

The present invention as described above, by allowing the viewer to search the channel at a desired speed can eliminate the inconvenience of having to press the channel key for a predetermined time during the channel search, the desired volume in proportion to the drag speed even when adjusting the volume level By allowing the user to quickly move to a level, the inconvenience of having to hold down the volume key for a predetermined time is eliminated.
