The existing display device is a very common household appliance, which has been entered into the homes of people in all countries in the world for a long time, and a user can watch programs for entertainment through the display device. However, when the user in some countries switches channels by using the numeric keys on the control device, the user may not search for a desired program because of mistaking the numeric keys. The reason for such a problem may be that a user in some countries or regions memorizes a physical channel number for some reason, but the display apparatus searches for a channel with an input number acquired based on the numeric keys as a numeric channel number, and thus there is a problem that the user cannot find a program corresponding to a channel desired to be viewed.

In order to solve the above problem, an embodiment of the present application provides a method for switching channels of a display device, in which an input number is used as a digital channel number to search for a channel, and after a result is not obtained, the input number is used again as a physical channel number to search for a channel, so that a problem that a user inputs the input number to search for a channel according to the digital channel number, and the result does not occur is solved.

In some embodiments, the display device searches for a channel by using a full frequency channel searching method, where the specific process includes setting a lowest frequency point and a highest frequency point, starting from the lowest frequency point, increasing a frequency interval each time, sequentially searching for the channel to the highest frequency point, and storing channel information of the searched channel. In some embodiments, the channel information includes a frequency point, a physical channel number uniquely corresponding to the frequency point, and a digital channel number corresponding to the frequency point. It should be explained that, since a plurality of digital channels can be played in one channel, each digital channel corresponds to one digital channel number, one frequency point can correspond to a plurality of digital channel numbers.

In some embodiments, as shown in fig. 5, the method comprises:

s100, receiving a channel switching instruction generated according to input numbers, and taking the input numbers as digital channel numbers. S200, determining whether a first channel corresponding to the digital channel number exists.

Illustratively, the channel switching instruction may be generated by pressing a numeric key with the control device while the user is watching the program. In some embodiments, the channel switching instruction is generated when the user presses the number key and does not receive other key operations within a preset time, for example, the user may press the number key 2 by using the control device and does not receive an operation of pressing other keys by the user within the preset time, and the channel switching instruction is generated according to the input number 2. As shown in fig. 6, if the user continues to press the number key 0 within a preset time after pressing the number key 2 by using the control device, and does not receive the operation of another key within the preset time after pressing the number key 0, a channel switching instruction is generated according to the input number 20 at this time.

In some embodiments, the step of determining whether a first channel corresponding to the digital channel number exists comprises:

and judging whether the digital channel number is the same as a pre-stored digital channel number. In some embodiments, the display device searches channels by using a full-frequency channel searching method to obtain channel information, where the channel information includes a digital channel number and the like, and compares the digital channel number in the channel information as a pre-stored digital channel number with the digital channel number using the input number as the digital channel number.

And if the number of the digital channel as the input number is the same as the number of the prestored digital channel, taking the channel corresponding to the prestored digital channel number as a first channel. Illustratively, as shown in table 1, table 1 is a channel information table, the digital channel number in table 1 is a pre-stored digital channel number, and the physical channel number in table 1 is a pre-stored physical channel number. When the input number is 7.31, which is the digital channel number, and is looked up in table 1, it can be seen that there is a pre-stored digital channel number 7.31 that is the same as digital channel number 7.31, and thus there is a first channel.

TABLE 1

Physical channel number	Frequency point	Digital channel number
			16	485.143MHz	7.31
19	503.143MHz	5.1
			20	509.143MHz	2.11/2.12/2.13
21	515.143MHz	35.1/35.2/35.3

In the embodiment of the application, for the convenience of the user, when the input number is incomplete compared with the pre-stored digital channel number, or the input number is more than the number of digits of the pre-stored digital channel number, the first channel can still be determined. And when the digital channel number is different from the prestored digital channel number, matching according to an analog matching rule. If the matching is successful and the number of the matching results is 1, taking a channel corresponding to a pre-stored digital channel number matched with the digital channel number as a first channel; if the matching is successful and the number of the matched pre-stored digital channel numbers is more than 1, taking a channel corresponding to the pre-stored digital channel number arranged at the head as a first channel; if the match fails, then there is no first channel.

Illustratively, when the input number is 7, since the bits of the pre-stored digital channel number 7.31 in table 1 are the same as 7, it is determined that the channel corresponding to the pre-stored digital channel number 7.31 is the first channel. When the input number is 2.1, the first two digits of the pre-stored digital channel numbers 2.11, 2.12, and 2.13 are all the same as 2.1, and the channel corresponding to the pre-stored digital channel number 2.11 arranged at the top is determined as the first channel. When the input number is 7.3111, and the first three digits of 7.3111 are the same as the pre-stored digital channel number 7.31, the channel corresponding to the pre-stored digital channel number 7.31 can be used as the first channel. In the embodiment of the present application, specific contents of the analog matching rule are not limited, and it is sufficient to inherit that when the input number is incomplete compared with the pre-stored digital channel number, or the input number is more than the number of digits of the pre-stored digital channel number, the meaning of the first channel can still be determined.

In some embodiments, S300, the input number is used as a digital channel number, and if the first channel exists, the display is controlled to display a program corresponding to the first channel. And when a first channel corresponding to the digital channel number exists, playing the program of the first channel according to the digital channel number and the corresponding frequency point. In some embodiments, the digital channel number obtains the channel number according to the mapping relationship, and the program of the first channel is played by using the channel number and the frequency point, for example, referring to table 1 again, when the digital channel number corresponding to the first channel is 2.11, the channel number of the digital channel number is determined to be 1000 according to the mapping relationship, and the program of the first channel is played by using the channel number 1000 and the frequency point to be 509.143 MHz.

S400, if the first channel does not exist, processing the input number, and taking the processed input number as a physical channel number. And S500, determining whether a second channel corresponding to the physical channel number exists. In order to avoid memory errors of a user, when the input number is used as the number of the digital channel and the first channel is not searched, the input number is used as the number of the physical channel to search the channel for the second time.

In some embodiments, the step of processing the input number comprises:

it is determined whether a preset symbol is present in the input number.

If the preset symbol exists, taking the number in the input numbers before the preset symbol as the processed input number; and if the preset symbol does not exist, the input number does not need to be processed, and the input number is directly used as the processed input number.

In the embodiment of the present application, the preset symbol may be a decimal point or a horizontal bar, and since the physical channel numbers are integers, input numbers that do not meet the rule need to be processed. Illustratively, if the input digit is a decimal digit, the input digit is processed, and the part in front of the decimal digit point of the input digit is used as the processed input digit, and illustratively, when the input digit is 21.12, the input digit is processed to obtain the processed input digit 21, and the processed input digit 21 is used as a physical channel number to determine whether a second channel corresponding to the physical channel number exists.

In some embodiments, the channel information further includes a physical channel number, and the physical channel number in the channel information is taken as a pre-stored physical channel number. The input number is used as a physical channel number, and a prestored physical channel number which is the same as the physical channel number is searched in the channel information.

In some embodiments, the determining whether the second channel exists comprises: and if the channel information has a pre-stored physical channel number which is the same as the physical channel number and the physical channel number corresponds to a digital channel number, the channel corresponding to the digital channel number is a second channel. Illustratively, when the input number is 16.1, the input number is processed to obtain the processed input number 16, the processed input number 16 is used as a physical channel number, referring to table 1, a prestored physical channel number identical to the physical channel number exists in table 1, and a channel corresponding to a digital channel number 7.31 corresponding to the prestored physical channel number is determined to be a second channel.

And if the channel information has a prestored physical channel number which is the same as the physical channel number, and the physical channel number corresponds to a plurality of digital channel numbers, the channel corresponding to the digital channel number arranged at the head is a second channel. Illustratively, when the input number is 21.12, the input number is processed to obtain the processed input number 21, the processed input number 21 is used as a physical channel number, referring to table 1, a prestored physical channel number identical to the physical channel number exists in table 1, the prestored physical channel number corresponds to a plurality of digital channel numbers, and a channel corresponding to the digital channel number 35.1 arranged at the head is used as the second channel.

And if the pre-stored physical channel number which is the same as the physical channel number does not exist in the channel information, the second channel does not exist.

In some embodiments, S600, if the second channel exists, controlling a display to display a program corresponding to the second channel. In the embodiment of the present application, the process of displaying the program corresponding to the second channel is the same as the process of displaying the program corresponding to the first channel mentioned above, and details are not repeated here.

In some embodiments, in order to avoid that the physical channel number in the channel information is not fully stored, and the user cannot find a channel desired to be watched, in this embodiment of the application, the physical channel number is used to continue searching for a channel in another manner, and the method further includes:

s700, if the second channel does not exist, determining whether the physical channel number is in a reasonable range. Since the physical channel numbers of different countries are all within a fixed range, the physical channel numbers may be, for example, 2-69. In some embodiments, since the lowest frequency point and the highest frequency point set when the full frequency channel searching manner is used are not suitable, the content in the channel information may be incomplete, and therefore, if the physical channel number is within a reasonable range, a corresponding channel may exist.

In some embodiments, the method comprises: and S800, if the physical channel number is not in a reasonable range, controlling the display to continuously play the current program. Illustratively, the physical channel number is 1, and the reasonable range of the physical channel number is 2-69, so that the physical channel number is not in the reasonable range, and it is determined that there is no channel corresponding to the input number, and the display does not switch to play the program at the current time.

In some embodiments, S900, if the physical channel number is in a reasonable range, starting a single frequency point channel search according to the physical channel number.

In some embodiments, S800, if the physical channel number is in a reasonable range, starting a single frequency point channel search according to the physical channel number. The single frequency point channel searching process comprises the steps that an upper layer User Interface (UI) issues a physical channel number or directly issues a frequency point, a bottom layer is processed by a tuner and a Demodulator, if the frequency can be locked, a channel under the current frequency point can be analyzed from a code stream, and the single frequency point channel searching process is completed.

In some embodiments, S1000, if a channel is searched, controlling the display to play the first searched channel. Since a plurality of digital channels are corresponding to the physical channel number, that is, a plurality of digital channel numbers are corresponding to the physical channel number, a plurality of channels may be searched.

In some embodiments, S1100, if the channel is not searched, the display is controlled to continue playing the program of the current channel. In the embodiment of the application, if a channel is not searched, which indicates that no channel corresponding to the input number exists, the display does not switch the program corresponding to the currently played channel.

In the embodiment of the application, in addition to using the above-mentioned display device to play a program, a user generates a channel switching instruction by pressing a number key on the control device, in some embodiments, a number channel number control may be displayed on the user interface for the user to select, and a channel switching instruction is generated. In this case, the method for the display device to switch channels includes:

and receiving an instruction for displaying the physical channel number, and controlling the display equipment to display the user interface provided with the physical channel number control. Illustratively, the user moves the selector to the physical channel number display control via the control device and presses the enter key on the control device, and the user interface jumps to the user interface shown in fig. 7, where the physical channel number control, illustratively, physical

channel number control

701 and 704 in fig. 7, is displayed.

Note that a control refers to a visual object that is displayed in the GUI to represent corresponding content such as an icon, a thumbnail, a video clip, a link, and the like in the display device.

The display forms of the controls are generally diversified. For example, the control may include textual content and/or an image for displaying a thumbnail related to the textual content. As another example, the control can be text and/or an icon of the application. It should also be noted that the selector is used to indicate that any one of the controls has been selected, such as the focus object. In one aspect, the control may be selected or controlled by controlling movement of a display focus object in the display device according to an input from a user through the control means. Such as: the user can select and control the controls by controlling the movement of the focus object between the controls through the directional keys on the control device. On the other hand, the movement of each control displayed in the display device may be controlled according to the input of the user through the control device to cause the focus object to select or control the control. Such as: the user can control all the controls to move left and right through the direction keys on the control device, so that the focus object can be selected and the controls can be controlled when the position of the focus object is kept unchanged. The form of identification of the selector is often diversified. For example, as shown in fig. 7, the physical channel number control 701 may identify the location of the focal object by changing the border line, size, color, transparency, and outline of the text or image of the focal control, and/or the font, and may implement or identify the location of the focal object by setting the background color of the control.

And receiving an instruction of selecting the physical channel number control, and controlling the display equipment to display the digital channel number control corresponding to the physical channel number control. Illustratively, in the user interface of fig. 7, the user moves the selector to the physical channel number control 701 through the control device and presses the enter key on the control device, and the user interface jumps to the user interface shown in fig. 8, where the digital channel control 7011 corresponding to the physical channel control is displayed on the user interface. As shown in fig. 9, when the number of the digital channel controls corresponding to the physical channel control is plural, the digital channel controls 7031 and 7033 may be displayed on the user interface in a list form.

And receiving a channel switching instruction of the selected digital channel number control, and controlling display equipment to play the program of the channel corresponding to the digital channel number control. Illustratively, as shown in fig. 8, the user moves the selector to the digital channel control 7011 through the control device, and presses the enter key on the control device, so as to control the user interface on the display device to jump, and play the program of the channel corresponding to the digital channel number 7.31.
