Description

Method and system for implementing channel input by using touch remote controller

Technical field

The invention belongs to the technical field of digital television, and in particular relates to a method and a system for realizing channel input by using a touch remote controller.

Background technique

With the improvement of social material and cultural level and the promotion of reliable communication methods such as digital TV, there are more and more broadcast TV channels that can be received by existing users. It is most common for users to frequently change channels (ie, channel switching) while watching TV. An act of. A variety of channel switching methods are provided in the existing television system. For example, in order to enable the user to switch to the target channel, scrolling to locate or directly input the target channel number is usually adopted. The earliest TV input system used the arrow keys on the remote control to scroll the channel list, or the digital buttons on the remote control to realize digital input. With the development of touch technology, many remote controllers provide touch. The board, the scrolling channel list can be realized by the finger on the touchpad in the up and down direction (or the left and right direction, as specified by the TV system), and the input number is clicked on the touchpad by the finger on the touchpad or the television. The number keys in the soft keyboard displayed on the screen are implemented.

However, in the process of implementing the present invention, the inventors have found that the touch input method of the prior art still has deficiencies. First of all, entering a number to select a channel is the most common mode of operation. The method of scrolling through the channel list usually requires a long time to scroll through the list when the number of channels is large. A channel change will have a large amount of operation, especially the current general TV. There are more than 100 channels, and each time the flip list is a lot of time, it is easy to get bored. If you use the soft keyboard to input, you need to accurately position the finger on the touchpad, which has high requirements on the user's operation accuracy. This makes most operations not smooth, and can not achieve fast digital input, which is easy to cause. Input error; in addition, the direct digital input cannot browse the channel information, and the user needs to clearly know the situation to select the channel when inputting, and the wrong situation may occur when the error is selected.

detailed description

The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It is understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the embodiment of the present invention, a method for inputting a number through a remote control touchpad to perform channel switching is provided firstly. The method displays a compass composed of one digit on the input screen when the channel is switched, and maps the direction in which the finger is swiped on the touchpad to the direction of the circle center to the circle number, and the pointer selects the corresponding number. Thus, a one-digit selection is completed; then, the system intelligently judges with the selected process and the selected digital condition and channel condition, and further input is performed to complete the channel switching.

Referring to FIG. 1, in an embodiment of the present invention, a method for implementing channel input by using a touch remote controller includes the following steps:

S03, the number other than the selected number disappears in the compass, if the user's finger does not leave the touchpad and then enter a digit does not exceed the channel serial number range, step S04; otherwise, step S05;

The specific implementation of the method of the present invention will now be described in a few more specific embodiments.

Example 1

In Embodiment 1 of the present invention, assuming that a certain television has 143 channels, a certain channel program is currently being played, and the user wants to switch to channel number 97, the implementation process of Embodiment 1 is as follows:

First, the user holds the remote control and puts the finger 1 on the remote control touchpad 2 to touch it (in the actual design, it is preferred that the finger stays on the surface of the touchpad for more than 0.8 seconds), and the remote touches the physical touch of the finger. Converted into an electrical signal for transmission to the television system, then the television system draws a one-digit compass 4 at a central position on the television picture 3, the compass is a circle of numbers uniformly distributed from 0 to 9 for a week (by default, the television has a number 0) For channels without channel 0, the compass will only display 1 to 9), and the corresponding channel name will be displayed under each number. The schematic of this step is shown in Figure 2. The compass 4 is preferably presented in a translucent state.

Then, the user sees the number 9 appearing in the upper left part of the compass, and the finger 1 is swiped to the upper left on the touchpad 2 (approximately 11 o'clock direction), as shown by the arrow on the touchpad 2 in FIG. The remote controller converts the swipe motion into an electrical signal for transmission to the television system, and the television system maps the swipe direction to a point on the television screen 3 from the center of the compass 4 to the circumference circle, and displays the swipe on the screen 3 The trajectory is such that the user can better control the direction during the swiping process, as indicated by the arrow on the television screen 4 of Fig. 3, to find the number on the pointing.

The system finds the number 9 according to the pointing, so that the number 9 is highlighted in the television picture 3 to indicate that the number 9 is the currently selected number (the circle is surrounded by the number in the figure to indicate that it is highlighted), and the compass is displayed. The other numbers in 4 and the corresponding channel names are hidden (the screen effect can be gradually changed from translucent to fully transparent), and the finger 1 remains on the touchpad 2 at this time. This step is shown in Figure 4.

The system determines whether the next compass should be drawn: since the maximum number of channel numbers is 143, it is three digits, and the current picture has only one selected number "9", 3-1=2>1, and then select a digit. It does not exceed the total channel range; and since the finger 1 does not leave the touchpad 2, it is judged that the user is likely to select another number, and then draws again on the television screen 3 with the selected number "9" as the center. A two-digit compass 5, the compass 5 is uniformly distributed by numbers 90 to 99, and the channel name corresponding to the number is displayed under each number. This step is schematically shown in FIG. 5.

The user sees the number 97 appearing in the lower left part of the compass 5, and the finger 1 continues to move to the lower left on the touchpad 2 (approximately 8 o'clock direction), as indicated by the arrow on the touchpad in FIG. The remote controller converts the swipe motion into an electrical signal for transmission to the television system, and the television system maps the swipe direction to a pointing point on the television screen 3 from the center of the compass 5 to the circumference circle, and displays the swipe track on the screen. To make the user better control the direction during the stroke process, as shown by the arrow on the TV screen of Figure 6, find the number on the pointing.

The system finds the number 97 according to the pointer, and then highlights the number 97 in the television picture 3 to indicate that it is selected (in the figure, the circle is surrounded by the number to indicate that it is highlighted), and the other in the compass 5 The number and the corresponding channel name are hidden (in the screen effect, it can be changed from translucent to fully transparent), and the last selected number 9 and the corresponding channel name are also hidden, as shown in Figure 7, at this time, the finger 1 is still on the touchpad 2.

The system judges whether the next compass needs to be drawn: since the maximum value of the channel number is 143, it is a three-digit number, and the current picture already has two selected numbers "9", "7", 3-2=1, The numbers "9" and "7" selected in succession will be combined into the number "97". Since the additional digit is at least "97" × 10 = 970 > 143, it is judged that the compass should not be drawn again.

The system determines that the input is completed, and the system switches the channel to No. 97, as shown in FIG. 8, and ends the channel switching.

Example 2

In Embodiment 2 of the present invention, it is also assumed that a television has 143 channels, and a program of a certain channel is currently being played, and the user wants to switch to channel No. 9.

Different from Embodiment 1, after selecting one digit "9", the user can have two choices. One is to click the touchpad with a finger after selecting the number "9", the system does not draw or End the drawing of the new two-digit compass, and directly turn to the channel switching step; the other is that the finger stops swiping and waits, and the user's finger is found within a certain time (for example, 0.8 seconds) after the newly drawn two-digit compass is displayed. When leaving the touchpad or not detecting the action of the user's finger swipe, the newly appearing compass is hidden and the channel switching step is performed; when the channel switching step is executed, the highlighted number 9 is flashed, that is, the screen is switched to 9 No. channel, while the number 9 is hidden.

Example 3

In Embodiment 2 of the present invention, it is also assumed that a television has 143 channels, and a program of a certain channel is currently being played, and the user wants to switch to channel 141.

Different from Embodiment 1, after the two digits are selected, if the click instruction of the user's finger is received, the channel switching step can be directly performed; and if the direct switching instruction is not received, the maximum value of the channel number is 143. It is 3 digits. Currently, the two digits "1" and "4" have been selected, 3-2=1. If you select a digit, then at least "14" × 10 = 140 < 143, so the judgment should be drawn again. Compass; then the value of the single digit of the channel's maximum serial number 143 is obtained to obtain the number 3, and a three-digit compass 6 composed of four numbers of 140 to 143 is drawn centering on the currently selected number "14". The opportunity for the user to further select the number in screen 3 is shown in FIG.

Assume that the first two compasses appear from the single digits from 0 to 9 clockwise and start from the 12 o'clock direction. The user further selects the number "141", then the finger 1 is swiped on the touchpad 2. As shown by the arrows on the touchpad 2 of Figure 9.

The process after the last digit "141" is selected is similar to that of Embodiment 1, and will not be described again.

It should be noted that, at the beginning of the above embodiment, after the touch panel detects a touch of the finger, the system starts to appear on the television screen. In fact, other functions may be used to call up the function, such as a finger. Double-click action on the touchpad; if the number is selected, it can be highlighted as long as it is displayed, not necessarily highlighted, or it can be obvious discoloration, etc., which are within the scope of protection of the present invention. within.

The technical solution in the above embodiments of the present invention has the following obvious beneficial effects:

1.Because the touchpad interacts with the compass on the TV screen, you only need to slide your finger in the general direction to realize a digital selection, which is easy and easy to operate and has high accuracy. You don't need to look down at the remote control to be able to choose accurately, and it is not as difficult to locate as clicking on a soft keyboard.

2. Since each selection is based on the compass that was redrawn on the last selected number, the user will correspond to the current position of the finger (remote control touchpad) each time. The center of the current compass on the screen, directly select the next sliding direction to achieve the next number. In the whole selection process of a series of numbers, there is no need to raise the finger and consider the problem corresponding to the position of the touch panel and the TV screen. As with the use of a soft keyboard, multiple precise positioning clicks are required. The result is that the finger is gently swiped on the remote control touchpad, which is equivalent to drawing a continuous curve, that is, the input of the target channel serial number is realized, and the whole The process is simple, easy, fast, and natural, with a good user experience and experience;

3. In the process of digital selection, the system can intelligently judge whether it is necessary to draw a compass again according to the number and channel configuration that the user has input, and judge and control the selection of the compass only to display the necessary numbers, so that the screen The most concise, the simplest finger swipe, the channel switching is more timely;

4. Since the compass appears on the TV screen, the numbers selected in turn will be retained before the channel switching is completed and displayed as a number on the screen after all the selections are completed. This is a typical "what you see is what you get" control method. The process and the results of each step are very intuitive, and any type of user will feel easy to learn and use;

5. After selecting some numbers, the user can either notify the system to select the channel switching immediately after clicking the action, or the system detects that the finger leaves the touchpad; or the inaction method, that is, the newly appearing compass of the system in a certain period of time If no signal is received, it is judged that the user has selected the number, and then the channel switching is implemented. The two ways are the same but can meet the different habits and styles of different users;

6. Since the compass is translucent, it has less impact on the currently playing screen, making it easier to enter the channel serial number.

The above is only the preferred embodiment of the present invention, and is not intended to limit the present invention. Any modifications, variations, equivalents, and improvements made within the spirit and scope of the present invention should be included in the present invention. Within the scope of protection of the invention.
