Abstract

PURPOSE: A key process acceleration method for a television is provided to quickly move a coordinate or a channel on a screen by adding an acceleration function in a directional key or a channel up/down key. CONSTITUTION: A key receiving unit receives a signal of a key pushed by a user, and transmits the received key signal to a system control unit(S11). The system control unit judges whether the pushed key is a channel up/down key or a directional key(S12). If the pushed key is the channel up/down key or the directional key, the system control unit calculates a time while the user pushes the key(S13) and decides an applicable acceleration throughput(S14). The system control unit judges whether the pushed key is the channel up/down key(S15). If the pushed key is the channel up/down key, the system control unit judges whether the acceleration throughput exceeds a minimum time necessary for channel conversion(S18). If the acceleration throughput exceeds the minimum time necessary for the channel conversion, the system control unit changes a channel number and displays the changed channel number on an OSD(On Screen Display). If the displayed channel number is selected, the system control unit moves a current channel to the selected channel(S20). If the acceleration throughput does not exceed the minimum time necessary for the channel conversion, the system control unit moves the channel according to the acceleration throughput(S19). The system control unit judges whether the pushed key is the directional key(S16). If the pushed key is the directional key, the system control unit moves a coordinate on a screen according to the acceleration throughput(S17).

Description

Key processing acceleration method of TV {KEY PROCESS ACCELERATION METHOD FOR TELEVISION}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for accelerating key processing of a television, and more particularly, to a method for accelerating key processing of a television, by adding an acceleration function to a direction key or a channel up / down key so that coordinate movement or channel movement can be performed quickly on a screen.

In recent years, mass media have provided a number of channels to viewers through more media (satellite, terrestrial, and cable) to meet diversified viewers' needs. In addition, users can use various advanced functions as the performance of these devices is rapidly improved, such as receiving a digital broadcast using a television or a set-top box, or accessing the Internet.

However, as the number of channels increases or the capabilities of televisions and set-top boxes become more advanced, the user can select the desired channel by entering channel up / down keys in a number of channels, for example, or in remote televisions such as high-definition televisions. In order to perform operations such as moving a mouse by using a direction key of, the viewer has to suffer inconvenience in the conventional key processing method without the acceleration function.

The following method has been disclosed as a related art created to reduce the inconvenience of the viewer.

In the remote controller, the method of treating the user as if the user repeatedly presses the key at regular intervals is the most common key processing method. However, in order to have the same effect as pressing the key several times without the acceleration function, the same key must be held for a long time. There is a problem.

The method of directly inputting the channel number desired by the viewer or configuring the preferred channel list is inconvenient to memorize all the channel numbers desired by the viewer or to configure the preferred channel list through a separate operation. In addition, if the number of preferred channel lists increases, this method is also difficult to be an alternative.

Connecting a separate external device to replace the remote controller, such as a wireless mouse, is a burden to add a separate external device instead of the existing remote controller without the acceleration function, and is applicable to a TV-specific function such as channel switching. There is no problem.

Accordingly, the present invention has been made in view of the above problems, and when the user presses a key using a remote controller, the key press time is calculated, and as the time is increased, the direction key or channel up / down key is pressed. It is an object of the present invention to provide a method for accelerating key processing of a television, so that the operation can be speeded up.

The present invention for achieving the above object, the step of receiving a key pressed by the user in the key receiving unit and transmitting to the system control unit; Determining, by the system controller, whether the received key is a channel up / down key or a direction key, if it is true, calculating an amount of time the user presses the key to determine an acceleration throughput to be applied; It is determined whether the received key is a channel up / down key. If it is true, it is determined whether the acceleration throughput exceeds the minimum time required for channel switching. If it is exceeded, the channel number is displayed by changing the channel number in the OSD of the screen. Moving to; Moving the channel according to the accelerated throughput if the accelerated throughput does not exceed the minimum time required for channel switching; Determining whether the received key is a direction key, and if true, moving the coordinates of the arrow on the screen according to the acceleration throughput.

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

1 is a block diagram showing a configuration of a television in which the present invention is performed, and as shown therein, a key receiving unit 24 for receiving a key pressed by a user in the remote controller 10; A tuner 21 for tuning a desired channel in a broadcast signal received through an antenna; A decoder (22) for recovering the digital broadcast signal received through the tuner (21); A display unit 23 for outputting a video and audio signal reconstructed by the decoder 22 to a user; It is composed of a system control unit 25 for controlling each of the components described as follows.

When the user presses a desired key on the keypad of the remote controller 10, the remote controller 10 carries the corresponding key code on the infrared signal and transmits it.

The key receiving unit 24 of the television 20 receives a key code transmitted on an infrared signal and transmits it to the system control unit 25.

The system controller 25 controls the tuner 21, the decoder 22, and the display 23 to analyze the keycode and perform a corresponding process.

2 is an operation flowchart of a method for accelerating key processing of a television according to the present invention, as shown therein, receiving a key pressed by a user at a key receiving unit and transmitting the received key to a system controller (S11); Judging whether the key received from the system controller is a channel up / down key or a direction key, if true, determining an acceleration throughput to be applied by calculating a time for which the user presses the key (S12 to S14); It is determined whether the received key is a channel up / down key, and if it is true, it is determined whether the acceleration throughput exceeds the minimum time required for channel switching. Steps S15, S18, S20; Moving the channel according to the accelerated throughput if the accelerated throughput does not exceed the minimum time required for channel switching (S19); It is determined whether the received key is a direction key, and if true, shifting the coordinates of the arrow on the screen according to the acceleration throughput (S16 and S17).

The user can enter a key using the remote controller or press an external button on the television / set top box. When the user inputs the key, the key receiving unit receives the key and transmits the key code to the system control unit (S11).

The system control unit analyzes the keycode and performs a task to be processed. In this case, if the input key is a channel up / down key or a direction key, it is determined that an acceleration function such as coordinate movement on the screen is required (S12).

The system controller determines the acceleration throughput to be applied by calculating the time for which the user presses the key (S13 and S14).

Thereafter, it is determined whether the pressed key is a channel up / down key or a direction key, and if the direction key is used, the coordinates are shifted according to the acceleration throughput (S16 and S17).

For example, FIG. 3 is an exemplary view of coordinate movement of a direction key on a screen according to the embodiment of FIG. 2, and illustrates an example in which an arrow 30 moves coordinates on a screen by using a direction key of a remote controller. If the user keeps pressing the right direction key on the remote controller, the coordinate shift value on the screen increases with time and reaches the desired point in a shorter time.

If the pressed key is a channel up / down key and the user keeps pressing the channel up / down key, the channel switching speed is processed faster as time passes, so that the user can move to a desired channel in a shorter time (S18, S19).

At this time, if the accelerated throughput exceeds the minimum time required for channel switching due to physical constraints, the user can select the desired channel by changing only the channel number in the OSD (On Screen Display) output on the screen without actually switching channels. (S18, S20).

Accelerated throughput or processing methods can be adjusted as appropriate for the conditions that need to be addressed.

As described in detail above, the present invention calculates the time the user pressed the key to perform the key processing operation in accordance with the accelerated throughput proportional to this time, so that the same key is pressed several times during the key input using the existing remote controller Or to eliminate the inconvenience of pressing for a long time has the effect of providing a means for the user to operate the television or set-top box more efficiently.
