The audio output interface 285 is used for receiving an audio signal output by the audio processor 280 under the control of the controller 250, and the audio output interface 285 may include a speaker 286 or an external sound output terminal 287, such as an earphone output terminal, for outputting to a generating device of an external device.

In other exemplary embodiments, video processor 270 may comprise one or more chips. Audio processor 280 may also comprise one or more chips.

And, in other exemplary embodiments, the video processor 270 and the audio processor 280 may be separate chips or may be integrated with the controller 250 in one or more chips.

And a power supply 290 for supplying power supply support to the display apparatus 200 from the power input from the external power source under the control of the controller 250. The power supply 290 may be a built-in power supply circuit installed inside the display apparatus 200 or may be a power supply installed outside the display apparatus 200.

The embodiment of the invention also provides a scheme for applying the input method to the display equipment. Since the display device supports soft keyboard input, the soft keyboard view can be divided into 34, 35, 36, 37, 38, 39, 40, 46, 54 key types, etc. according to the language. As shown in fig. 2, a manner of applying the input method provided by the embodiment of the present invention to the display device is described by taking an example that the software keyboard includes 34 keys:

the soft keyboard view shown in fig. 2, which collectively includes 4 rows, wherein the first row includes 10 key values, the second row and the third row each include 9 key values, and the fourth row includes 6 key values; the key values on the soft keyboard are stored as corresponding two-dimensional arrays, for example, the first row corresponds to key _ layout _ number [0] [0] to key _ layout _ number [0] [9], the second row corresponds to key _ layout _ number [1] [0] to key _ layout _ number [1] [8], the third row corresponds to key _ layout _ number [2] [0] to key _ layout _ number [2] [8], and the fourth row corresponds to key _ layout _ number [3] [0] to key _ layout _ number [3] [5 ].

When a user operates an 'up' key in direction keys in a remote controller, the position of a remote controller focus is judged firstly, if the position of the remote controller focus is in a first row, a word selection module is called when the user clicks the 'up' key, and the remote controller focus is adjusted to a middle key of the word selection module;

it should be noted that, as shown in fig. 3, a row above the first row of the soft keyboard is the word selection module, and there are three key values in total, and one-dimensional array storage may be used, and it is assumed that the three key values from left to right of the word selection module in the soft keyboard view are stored by using the sunsets [0] to the sunsets [2 ].

If the focal point of the remote controller is on the second row or the third row of the soft keyboard, when the user clicks an 'up' key, subtracting 9 from the position of the focal point, namely jumping the focal point from the current position to the previous row; if the focus is in the fourth row, the focus is required to be judged to be specifically on the fifth key position, and if the focus is on the first to fourth keys, the user clicks an 'up' key, and 9 is subtracted from the current focus position; if the focus is at the fifth position keyboard _ layout _ number [3] [4], then jump to the penultimate position keyboard _ layout _ number [2] [7] of the previous row; if the focus is at the sixth position keyboard _ layout _ number [3] [5], then jump to the last position keyboard _ layout _ number [2] [8] of the previous row;

for example, if the current focus is on the letter "d" key in the soft keyboard shown in fig. 3, and the user clicks the "up" key, the focus will be changed from the "d" key to the "r" key; if the current focus is "in. And when the user clicks the 'up' key, the focus is adjusted to the'm' key.

When a user operates a 'down' key in direction keys in a remote controller, the position of a focal point of the remote controller is judged firstly, if the focal point is on a first key, namely, a key _ layout _ number [0] [0], the user clicks the 'down' key, then the focal point jumps to the first key, namely, the key _ layout _ number [1] [0] of a second row, and if the focal point is on second to ten keys of the first row, the position of the focal point is added with 9, thus the focal point jumps to the next row;

when the focus is in the second row, because the second row and the third row both contain 9 keys, when the remote controller key is pressed down, only 9 needs to be added to the focus position;

when the focus is in the third row, because the fourth row has only 6 keys, the first three keys in the fourth row only need to add 9 to the focus position, the fourth, fifth, sixth and seventh keys all jump to the key _ layout _ number [3] [3], the eighth key jumps to the second last key in the fourth row key _ layout _ number [3] [4], and the ninth key jumps to the last key in the fourth row key _ layout _ number [3] [5 ];

when the focus is on the fourth row (last row), the user presses the "down" button of the remote control, and no processing is performed.

When a user operates a left key in direction keys in a remote controller, whether a focus position is at the first position (head of a line) of a line where the focus is located is judged, if yes, processing is not needed, and if not, the focus position is reduced by 1.

When a user operates a right key in direction keys in a remote controller, whether the focus position is at the last position (tail of a line) of the line where the focus is positioned is judged, if yes, processing is not needed, and if not, the focus position is added with 1.

If the current focus is on the word selection module of the soft keyboard, the user clicks an 'up' key of the remote controller, the focus jumps to a second key of a second row in more candidate word modules above the word selection module, a two-dimensional array is used for representing key values in the more candidate word modules, and if moreSuggets [ ] [ ], the user clicks the 'up' key, and the focus jumps to moreSuggets [1] [1 ].

When the focus is in the word selection module, the user clicks the 'down' key of the remote controller, and the user jumps to the middle position of the soft keyboard view by default, namely, the keyboard _ layout _ number [0] [5 ].

When the focus is in the word selection module, the user clicks a left key of the remote controller to judge whether the focus is at the leftmost position (head of line), and if the focus is at the leftmost position, the focus is not processed; otherwise, the focus position is decremented by 1.

When the focus is in the word selection module, the user clicks a right key of the remote controller to judge whether the focus is at the rightmost position (tail of a line), and if the focus is at the rightmost position, the focus is not processed; otherwise, the focus position is incremented by 1.

When the focus is in more candidate word modules, the user clicks an 'up' key of a remote controller to judge whether the focus is in the first row, if so, the focus is not processed, and if not, the position of the focus is reduced by 3;

when the focus is in more candidate word modules, the user clicks a 'down' key of a remote controller to judge whether the focus is in a second row, if so, the focus is not processed, and if not, the focus position is increased by 3;

when the focus is in more candidate word modules, the user clicks a left key of the remote controller to judge whether the focus is at the first key position (head of a line) of each line, if so, the focus is not processed, and if not, the focus position is reduced by 1;

when the focus is in more candidate word modules, the user clicks the right key of the remote controller to judge whether the focus is at the last key position (tail of a line) of each line, if so, the focus is not processed, and if not, the focus position is added with 1.

After the input method is applied to the display device as described above, when the user needs to perform input, the user selects a desired content or triggers other functions of the input method on the soft keyboard of the display device by operating the direction keys on the remote controller.

At present, after a user inputs text content in an input box of a display interface of a display device, if the user needs to switch the type of the input text content, for example, case conversion and chinese-english conversion, because a remote controller can only control the position of a cursor in a mobile display, the user needs to operate a direction key in the remote controller to move the cursor to the position needing to be operated, delete the content needing to be adjusted and input the content again, and simultaneously, the user needs to switch an input method to an input method mode corresponding to the text type suitable for the requirement of the current operation, which is troublesome to operate.

Based on the above problem, the present invention provides a text type conversion method, as shown in fig. 4, including the following steps:

step S401, responding to a conversion instruction which is triggered by a user and used for indicating the type conversion of the text content in an input box of a user interface, determining the target text content which needs the type conversion in the text content, and converting the type of the target text content from the current type to the target type indicated by the conversion instruction;

and S402, controlling the text content of the target type to be displayed in a text input box on the user interface in a replacing manner.

The text type conversion method provided by the invention responds to a conversion instruction which is triggered by a user and used for performing type conversion on the text content in an input box of a user interface, determines the target text content which needs to be subjected to the type conversion in the text content, converts the type of the target text content into the target type, and replaces and displays the text content of the target type in the text input box on the user interface. According to the embodiment of the invention, after the target text content needing type conversion is acquired, the type of the target text content is directly converted into the target type, so that the operations of manually deleting and re-inputting by a user are omitted, the type conversion can be completed only by triggering the conversion instruction by the user, the method is more convenient and faster, the conversion type is not limited, the method can be set according to the user requirement, the personalized requirement of the user is met, and the user experience is improved.

In one possible embodiment, the user triggers the switching instruction by:

mode 1, pressing a designated key on a control device, wherein the designated key is configured to indicate type conversion of text content;

in a specific implementation, a designated key on the control device may be configured to instruct type conversion of the text content, and a conversion instruction for converting the text content is triggered after a user presses the designated key on the control device; for example, when the user presses a specific key of the pressure control device, which indicates the case conversion of the text content, a conversion instruction for case conversion of the text content input by the user may be triggered.

And 2, activating a specified key in the input method soft keyboard, wherein the specified key is configured to indicate to perform type conversion on the text content, and the user interface comprises the input method soft keyboard.

In a specific implementation, a specific key in a soft keyboard of the user interface may be configured to indicate type conversion of the text content, and when the specific key in the soft keyboard is activated by a user operation, a conversion instruction for converting the text content is triggered. For example, when the user activates a conversion key in the soft keyboard, which indicates the case conversion of the text content, a conversion instruction for case conversion of the text content input by the user may be triggered.

The display equipment responds to a conversion instruction triggered by a user, obtains text contents in an input box and determines target text contents needing type conversion in the text contents; determining a target type indicated by the conversion instruction according to the type conversion identifier; converting the type of the target text content from the current type into a target type; and displaying the target type text content in the input box, wherein the target type text content comprises the original text content which is not converted and the target text content which is converted.

In specific implementation, a type conversion identifier stored in a display device is read, wherein the type conversion identifier has two parameter values, namely true and false, and corresponds to a target type respectively; each time the user triggers the switching instruction, the type switching identifier is switched from the current value to another value, for example, the current value of the type switching identifier is true, and after the user triggers the switching instruction, the value of the type switching identifier is switched to false;

the display equipment responds to a conversion instruction triggered by a user, reads a value of a type conversion identifier stored in the display equipment, and determines a target type indicated by the conversion instruction according to a corresponding relation between a preset value of the type conversion identifier and the target type;

it should be noted that, when the type of the target text content is converted, the target text content may include a part of content whose current type is the target type, that is, the part of content does not need to be converted, and is displayed by using the original text content; or when the target text content is part of text content selected from all text contents by the user, the remaining unselected text contents do not need to be converted, and the original text content is used during display; therefore, when the target type text content is displayed in the input box after the type of the target text content is converted, the displayed target type text content comprises the original text content which is not converted and the converted target text content.

In one possible embodiment, the type of the text content includes at least a language of the text content, a case of the text content.

The following description is made for different conversion instructions, respectively:

1. the conversion instruction is an instruction to convert the language of the text content.

In one possible implementation, the conversion instruction is an instruction to convert the language of the text content, the target language indicated by the conversion instruction is determined according to the type conversion identifier, and the language of the target text content is converted into the target language.

In implementation, the target text content needing type conversion is determined from the text contents input by the user according to the following modes:

taking all text contents input by a user as target text contents; or

And taking part of text content selected by the user from the input text content as target text content.

In a specific implementation, when all text contents input by a user are taken as target text contents, the following method can be adopted:

if the user directly activates the conversion key on the soft keyboard, all text contents input by the user are taken as target text contents, and the conversion area can be set as the area where all the text contents are located; for example, if the text content input by the user contains n characters, the conversion region length is n.

When the part of the text content selected by the user in the input text content is used as the target text content, the user selects the starting position and the ending position of the target text content in the text content already input in the input box by operating the control device, and the target text content is obtained according to the starting position and the ending position of the target text content selected by the user.

In the specific implementation, if a user activates a switching key for switching a cursor function on a soft keyboard, the cursor function is switched to select target text content, and a confirmation key in a remote controller is clicked after a cursor is moved, the current cursor position is stored as a cursor starting position, the confirmation key in the remote controller is clicked after the cursor is moved again, the cursor position after the cursor is moved again is stored as a cursor ending position, text content between the cursor starting position and the cursor ending position is used as target text content, and a region between the cursor starting position and the cursor ending position is used as a conversion region.

For example, as shown in fig. 5, in an input interface displayed on a display of a display device, a text content input by a user is "SENse", the user activates a switch key "Change" for switching a cursor function on a soft keyboard, switches the cursor function to select a target text content, moves a cursor between "N" and "s" in the text, presses a determination key in a control device, so that a starting position of the cursor is between "N" and "s" in the text, moves the cursor to an end of the text again, presses the determination key in the control device, so that an ending position of the cursor is an end of the text, as shown in fig. 6, so that the determined target text content is "se".

In specific implementation, a language conversion key can be set in a soft keyboard of a user interface of display equipment, and a user can flexibly set the type of language conversion corresponding to the language conversion key; for example, the language conversion button may be set to switch between chinese and english, to convert between chinese and korean, or the like.

Assuming that a language conversion key set by a user is switched between Chinese and English, when the user presses an appointed key corresponding to language conversion on control equipment or activates the appointed key corresponding to language conversion in a soft keyboard to trigger a conversion instruction for converting the language of target text content into the target language, reading a type conversion identifier stored in display equipment, wherein if the value of the type conversion identifier is true, the target language is Chinese, and if the value of the type conversion identifier is false, the target language is English; and reading the type conversion identifier, determining a target language indicated by the conversion instruction according to the value of the type conversion identifier, and converting the language of the target text content.

Specifically, in response to a user pressing a designated key corresponding to language conversion on the control device or activating a designated key corresponding to language conversion in the soft keyboard, triggering a conversion instruction for converting the language of the target text content into the target language, and if the value of the type conversion identifier is read as true, determining that the target language is Chinese; and responding to a conversion instruction which is triggered to convert the language of the target text content into the target language by pressing the designated key corresponding to the language conversion on the control equipment again or activating the designated key corresponding to the language conversion in the soft keyboard, switching the value of the type conversion identifier from true to false, reading the value of the switched type conversion label as false, and determining that the target language is English.

One possible implementation converts the language of the target text content to the target language according to the following:

the method comprises the following steps of 1, calling an SDK translation tool, and inputting target text contents into the SDK translation tool to obtain converted text contents of a target language;

in specific implementation, an SDK translation tool is called, target text content is input into the SDK translation tool, the SDK translation tool is enabled to identify the language of the target text content, the target text content is converted into the text content of the target language, and then the converted text content of the target language is output.

And 2, calling a neural network model for multi-language translation, and inputting the target text content into the neural network model to obtain the converted text content of the target language.

Wherein, the neural network model of the multi-language translation is a trained neural network model;

before calling the neural network model of the multi-language translation, training the neural network model of the multi-language translation based on a large amount of sample data, and determining that the training of the neural network model of the multi-language translation is finished after the neural network model of the multi-language translation is converged;

it should be noted that the sample data used in the neural network model training process of the multi-language translation includes, but is not limited to: text data in a plurality of languages having the same paraphrases.

In specific implementation, a neural network model for performing multi-language translation is called, target text content is input into the neural network model, the neural network model is enabled to identify the language of the target text content, the target text content is converted into the text content of the target language, and then the converted text content of the target language is output.

For example, in the user interface displayed on the display of the display device shown in fig. 7, the text content input by the user is "King", the target text content is "King", the user activates the language conversion key "Trans" in the soft keyboard to trigger a conversion instruction for performing chinese-english conversion on the target text content, the value of the type conversion identifier stored in the display device is read as true, the target language indicated by the conversion instruction is chinese, and as shown in fig. 8, the target text content "King" is converted into "King" and displayed on the display of the display device;

or, the language conversion key "Trans" in the soft keyboard corresponds to the english-korean conversion, the user activates the language conversion key "Trans" in the soft keyboard to trigger a conversion instruction for performing the english-korean conversion on the target text content, the value of the type conversion identifier stored in the display device is read as true, the target language indicated by the instruction is korean, and as shown in fig. 9, the target text content "King" is converted into the korean

And displayed on the display of the display device.

2. The conversion instruction is a case-conversion instruction.

In one possible implementation manner, when the text content input by the user is an English character and the conversion instruction is a capital-lower case conversion instruction, if the target type indicated by the conversion instruction is determined to be capital letters according to the type conversion identifier, converting the type of the target text content into the capital letters according to the preset mapping relationship between the capital letters and the lowercase letters; or if the target type indicated by the conversion instruction is determined to be a lower case letter according to the type conversion identifier, converting the type of the target text content into the lower case letter according to the preset mapping relation between the upper case letter and the lower case letter.

It should be noted that the target text content is a target character which is related to the conversion instruction and needs to be subjected to type conversion.

In specific implementation, when the text content input by the user is an English character, in response to the user pressing a designated key corresponding to case conversion on the control device or activating a designated key corresponding to case conversion on the soft keyboard, triggering a conversion instruction for case conversion of the type of the target text content, reading the value of a type conversion identifier stored in the display device as true, and determining that the target type is a capital letter; if the value of the type conversion identifier is false, determining that the target type is a lowercase letter;

specifically, in response to a user pressing a designated key corresponding to language conversion on the control device or activating a designated key corresponding to case conversion in the soft keyboard, triggering a conversion instruction for converting the type of the target text content into the target type, and reading the value of the type conversion identifier as true, determining that the target type is capital letters; and responding to a conversion instruction which is triggered to convert the type of the target text content into the target type by pressing the designated key corresponding to the language conversion on the control equipment again or activating the designated key corresponding to the case conversion in the soft keyboard, switching the value of the type conversion identifier from true to false, reading the value of the switched type conversion label as false, and determining that the target type is the lowercase.

After the target type indicated by the conversion instruction is determined, converting the target text content into an array type from a character string, and respectively determining that each element in the array is a capital letter or a lowercase letter, and when the capital and lowercase types of the elements are different from the target type, converting the target type into the target type according to the mapping relation between the capital letters and the lowercase letters, specifically, converting the target type into the target type by using the conversion relation between the capital letters and the lowercase letters in ASCII codes, namely, subtracting 32 from the ASCII codes of the lowercase letters to convert the ASCII codes into the capital letters, or adding 32 to the ASCII codes of the uppercase letters to convert the ASCIcodes into the lowercase letters; and after the conversion of all elements in the target text content, which are different from the target type, converting the converted array into the character string type, and replacing the target text content with the converted text content of the target type.
