     BACKGROUND 
     An all-in-one machine is an integrative equipment which combines the functions of TV, touch and PC. At the present, most of all-in-one machines have the function of channel switching between VGA, HDMI, AV and YPBPR channels. However, only the content of one channel can be displayed at one time for the traditional switching between these channels. In a practical application, a user may perform an operation in a channel (referred to as channel A) firstly, and switch to a target channel (referred to as channel B) by a switch menu or button. The channel B may be displayed after system processing, and the user may perform some operations in the channel B, and then switch back to the channel A in the same way. The frequent switches in this way may be a tedious and time consuming process to the user. 
     When performing, operations respectively to the content of each of the channels, the user has to continuously change the channel currently displayed, making the whole process become cumbersome and inconvenient.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
     A method for multichannel touch control of an all-in-one machine includes: 
     step 1, providing a channel display window on a user interface, and setting up link buttons between the channel display window and corresponding channels respectively; and 
     step 2, setting up a multichannel touch control component on the user interface, receiving touch point information from a user, converting the touch point information into corresponding multichannel operation information, and performing operation on each channel based on the multichannel operation information. 
     In the method for multichannel touch control of an all-in-one machine, the display content of the multiple channels can be displayed by providing a channel display window on the user interface of the all-in-one machine, and with the multichannel touch control component set up on the user interface, the touch control operation on the multiple channels at the same time can be activated, for example, the display content of the multiple channels can be annotated, captured or printed at the same time, without having to respectively switch to the respective channel before performing the corresponding operation in the channel. In addition, it is convenient to switch between the multiple channels by the respective link button set up between the channel display window and the respective channel. 
     The channel display window may be set up in an Android system, and the channel display window may display the display content of the multiple channels at the same time, for example, the channel display window may display the content of all of the multiple channels in a plurality of sub windows which correspond to the multiple channels respectively. The channel display window may also be switched to display content of a certain channel alone, for example, when it is switched to a certain channel, the content corresponding to the channel may be displayed in the whole channel display window while the content of other channels may be hidden. Preferably, both of the size and location of the channel display window may be adjusted. 
     As a means to implement the link button, a drop-down box may be created in the menu bar, which includes a link button of each channel. When a link button is activated, the all-in-one machine can be switched from the current channel to another channel corresponding to the link button, and the image of the channel may be display in the channel display window. 
     Please refer to  FIG. 1 , which is a flow diagram illustrating a method for multichannel touch control of an all-in-one machine according to Example One of the present invention. 
     In the example, the method for multichannel touch control of an all-in-one machine can implement annotations for the multiple channels, including: 
     S 101 , providing a channel display window on a user interface, and setting up link buttons between the channel display window and corresponding channels respectively; 
     S 102 , providing a transparent annotation window above the channel display window, and receiving touch point information from a user; and 
     S 103 , converting the touch point information into annotations, and storing the annotations corresponding to each of the channels respectively. 
     In the embodiment, the transparent annotation window overlays the channel display window, but the transparent annotation window is transparent, so the feel of the image cannot be affected. The transparent annotation window can receive touch point information of the user, and covert the touch point information into a visual figure, character or line, which can be shown on the image as an annotation. The annotations respectively corresponding to each of the channels can be stored so as to display each of the annotations on the image at the same time. Thus it is convenience for the method according to the present invention to make annotations for all of the channels, to enhance the user experience. 
       FIG. 2  is a flow diagram shown an embodiment of a method for multichannel touch control of an all-in-one machine to implement annotations in multiple channels according to one embodiment of the present invention. The method includes: 
     S 201 , providing a channel display window on a user interface, and setting up link buttons between the channel display window and corresponding channels respectively; 
     S 202 , providing a transparent annotation window above the channel display window, and receiving touch point information from a user; 
     S 203 , collecting the touch point information according to the type of the annotation including graphic annotation, line annotation and/or text annotation; 
     S 204 , connecting the touch points into a line with a predefined color, to form an annotation, and displaying the annotation on the channel preview window in the current channel corresponding to the annotation; 
     S 205 , creating a graphic file package, a line file package and or text file package respectively; 
     S 206 , storing the annotation in a corresponding file package according to the type of the annotation, together with a coordinate location of the annotation with respect to the channel corresponding to the annotation; 
     S 207 , calling all of the annotations corresponding to the current channel from all file packages after switching to the current channel, and displaying the annotations according to their coordinate locations respectively. 
     The technical solution includes an Android user interface, a channel display window and a transparent annotation window configured to display an annotation. The channel display window is arranged on the Android user interface, and the size and location of the channel display window is adjustable. The transparent annotation window may overlay the channel display window. 
     With the present invention, the image information of other channels can be displayed on the area of the channel display window in the current user interface in real time, and it is possible to make an annotation at any location of the whole display screen. The present invention uses a three-tier structure, including an Android user interface layer, a channel display window layer and a transparent annotation layer. The Android user interface layer, as the lowest layer, is configured to display the current interface and control the location of the channel display window. The channel display window layer, as the middle layer, is configured to display information of other channels, and it would have to depend on the Android user interface layer which is used as a carrier. The transparent annotation layer, as the uppermost layer, is configured to receive user input and display annotations. 
     Specifically, the Android user interface layer may be implemented by the Activity of the Android, the channel display window layer may be implemented by the SurfaceView of the Android, and the transparent annotation layer may also be implemented by the SurfaceView of the Android. 
     When the transparent annotation window of the transparent annotation layer is in a writing mode to receive touch events of the user, the transparent annotation layer is responsible for processing the point data and forming a certain graphic element which may be display on the SurfaceView of this layer. Because this layer is transparent, the annotation looks like an annotation directly made on the channel display window layer. The writing mode can be determined by the type or pattern of the annotation. 
     In one embodiment, the types of the annotation include graphic annotation, line annotation and/or text annotation, and the wiring mode includes: 
     collecting the touch point information according to the type of the annotation; and 
     connecting the touch points into a line with a predefined color, to form an annotation, and displaying the annotation on the channel preview window in the current channel corresponding to the annotation. 
     Preferably, according to the information of the touch points, the starting point where the touch starts, the end point where the touch is end, and the sampling points between the starting point and the end point may be connected into a line. Preferably, if the sampling rate is high, an irregular line may be formed according to the touch of the user. If the type of the annotation is a graphic annotation, the starting point and the starting point may be connected to form a closed region. The annotation may be displayed on the image with a predefined color, such as red. 
     In addition, the graphic annotation or line annotation that has been formed may be edited by some operation, such as deletion or adding text. The deletion means cancelling the annotation. The adding text means adding a text annotation onto the graphic annotation or line annotation. 
     In another embodiment, the annotation includes a graphics library and a line library storing preset patterns. The wiring mode includes: 
     selecting the target style from the graphics library or the line library; 
     extracting starting point and end point coordinates from the touch point information; and 
     drawing a graphic element or a line of the target style between the starting point and the end point to form an annotation, and displaying the annotation on the channel preview window in the current channel corresponding to the annotation. 
     Different from the previous embodiment, basic types of annotation have been established in this embodiment so a graphic element or line of the selected target style can be drawn between the starting point and the end point once the coordinates of the starting point and the end point have been acquired. The annotation formed may be a straight line, a wave line, a circle, a rectangle or other basic patterns. 
     It can be seen that the operation of the annotation is only implemented by the transparent annotation layer. 
     In order to perform operations on the middle channel display window layer when the transparent annotation layer is under operations, a rectangular region object with the same size of the channel display winder layer is defined in the transparent annotation layer, which is called as a transparent annotation window. When the user performs a selecting operation on the transparent annotation window, whether the operation is within the rectangular region of the channel display window is determined, and if so, the operation will be executed in the rectangular region. The result of the execution may be informed to the Android user interface layer, and the Android user interface layer may adjust the size or location of the channel display window. The operations on the channel display window may include moving and zooming in and out. In addition, there may be a link button for changing channel. When performing operations on the channel display window; a drop-down box with a list of available channels may be provided that if the user selects a channel, the channel display window layer may switch to the channel for display. 
     In addition, the present invention may create a graphic file package, a line file package and/or text file package respectively, configured to store various types or patterns of the annotation, which is convenience for calling. The annotation may be stored in a corresponding file package according to its type, together with its coordinate location with respect to the channel corresponding to the annotation. In this way, it is known an annotation will be displayed on which location of which channel. 
     All of the annotations corresponding to the current channel may be called from all file packages after switching to the current channel, and the annotations may be displayed according to their coordinate locations respectively. Thus, even switching the channel, the annotation will not be lost. 
     Please refer to  FIG. 3 , which is a flow diagram illustrating a method for multichannel touch control of an all-in-one machine according to Example Two of the present invention. In the example, the method for multichannel touch control of an all-in-one machine can implement image-capturing for the multiple channels, including: 
     S 301 , providing a channel display window on a user interface, and setting up a link button between the channel display window and a corresponding channel; 
     S 302 , setting up an image-capturing activation button on the channel display window, and receiving the touch point information of the user after activating the image-capturing activation button; and 
     S 303 , creating an image-capturing box based on the touch point information, and storing the images captured by the image-capturing box respectively corresponding to each of the channel. 
     In the embodiment, in combination with the method according to the Example One, a transparent annotation window may overlay the channel display window, which is transparent, so the feel of the image cannot be affected. The transparent annotation window can receive touch point information of the user, and covert the touch point information into a visual figure, character or line, which can be shown on the image as an annotation. The annotations respectively corresponding to each of the channels can be stored so as to display each of the annotations on the image at the same time. In the meantime, the present invention is convenient to capture the display images respectively corresponding to each of the channel, to enhance the user experience. In particular, the image of the channel display window with an annotation can be captured that the image with the annotation can be stored. 
       FIG. 4  is a flow diagram shown an embodiment of a method for multichannel touch control of an all-in-one machine to implement image-capturing in multiple channels according to the present invention. The method includes: 
     S 401 , providing a channel display window on a user interface, and setting up link buttons between the channel display window and corresponding channels respectively; 
     S 402 , setting up an image-capturing activation button on the channel display window, and receiving the touch point information of the user after activating the image-capturing activation button; 
     S 403 , selecting a round box or a rectangular box as an image-capturing box; 
     S 404 , extracting starting point and end point coordinates from the touch point information; 
     S 405 , drawing a frame between the starling point and the end point to form the image-capturing box, and determining a storage path; 
     S 406 , naming each of the captured images according to a name of the corresponding channel and numbers, and storing in a selected file package; and 
     S 407 , calling a selected captured image from the file package after switching between channels, and dragging the captured image onto the riser interface for display. 
     The technical solution of this example can combine the method according to the Example One, including an Android user interface, u channel display window and a transparent annotation window configured to display an annotation. The channel display window is arranged on the Android user interface, and the size and location of the channel display window is adjustable. The transparent annotation window may overlay the channel display window. 
     The image with an annotation or without annotation may be captured. Firstly, the size, shape and location of the image-capturing box should be determined. Preferably the image-capturing box may include a round box and a rectangular box. Forming an image-capturing box according to the touch point information includes: 
     selecting the round box or the rectangular box; 
     extracting starting point and end point coordinates from the touch point information; 
     drawing a frame between the starting point and the end point to form the image-capturing box, and determining a storage path; and 
     inserting a cancellation prompt button that the round box or the rectangular box can be reselected when the cancellation prompt button is activated. 
     In order to perform operations on the middle channel display window layer when the transparent annotation layer is under operations, a rectangular region object with the same size of the channel display winder layer is defined in the transparent annotation layer, which is called as a transparent annotation window. When the user performs a selecting operation on the transparent annotation window; whether the operation is within the rectangular region of the channel display window is determined, and if so, the operation will be executed in the rectangular region. The result of the execution may be informed to the Android user interface layer, and the Android user interface layer may adjust the size or location of the channel display window. The operations on the channel display window may include moving and zooming in and out. In addition, there may be a link button for changing channel. When performing operations on the channel display window, a drop-down box with a list of available channels may be provided that if the user selects a channel, the channel display window layer may switch to the channel for display. 
     In addition, each of the captured images may be named according to a name of the corresponding channel and numbers, and may be stored in a selected file package. 
     In a preferred embodiment, when the user selects an operation of image-capturing, the system may start a service for image-capturing. The function of the service is to capture the content of whole screen, and store the content as a picture in a certain folder on a storage medium. When capturing the screen, the captured image is an image including content of other channels and with annotations, because the content of other channels and the annotations which have been made by the user on the channels are displayed in the screen. 
     Further, a deletion prompt button may be inserted. When the deletion prompt button is activated, the captured image that has been stored can be deleted. 
     The captured image may be selected according to the name of the image from the file package after switching between channels. And the captured image may be called and dragged onto the user interface for display. Thus, the acquired images corresponding to the multiple channels can be observed and compared after switching between channels. 
     Please refer to  FIG. 5 , which is a flow diagram illustrating a method for multichannel touch control of an all-in-one machine according to Example Three of the present invention. 
     In the example, the method for multichannel touch control of an all-in-one machine can implement print for the multiple channels, including: 
     S 501 , providing a channel display window on a user interface, and setting up link buttons between the channel display window and corresponding channels respectively; 
     S 502 , setting up a print activation button on the user interface, and receiving the touch point information of the user after activating the print activation button; and 
     S 503 , acquiring print areas based on the touch point information, putting the print areas respectively corresponding to each of the channels into the same print task, and outputting the print task to complete the print. 
     The technical solution of this example can combine the method according to the Example One. A transparent annotation window may overlay the channel display window, which is transparent, so the feel of the image cannot be affected. The transparent annotation window can receive touch point information of the user, and covert the touch point information into a visual figure, character or line, which can be shown on the image as an annotation. The annotations respectively corresponding to each of the channels can be stored so as to display each of the annotations on the image at the same time. In the meantime, the present invention is convenient to put the pages to be printed in respective channels into the same print task to output without switching the system, which saves testing time. The pages of all of the channels can be printed by driving an external printer only once, which does not take up too much of the channel resources of the printer. In particular, the image of the whole screen with the annotation in each channel can be printed, the image shown on the whole channel display window can be also printed, and a certain area captured from the channel display window can be further printed. The above same print task includes at least one page to be printed. 
       FIG. 6  is a flow diagram shown an embodiment of a method for multichannel touch control of an all-in-one machine to implement print of content in multiple channels according to the present invention. The method includes: 
     S 601 , providing a channel display window on a user interface, and setting up link buttons between the channel display window and corresponding channels respectively; 
     S 602 , setting up an image-capturing activation button on the channel display window, and receiving the touch point information of the user after activating the image-capturing activation button; 
     S 603 , extracting starting point and end point coordinates from the touch point information; 
     S 604 , drawing a frame between the starting point and the end point to form a print image box and storing the image box or the image in that box in a temporary folder; 
     S 605 , selecting target print image boxes to be printed from the temporary folder, and arranging the target print image boxes on the same page to be printed; 
     S 606 , outputting a print task to complete the print; and 
     S 607 , deleting the print image box corresponding to the print area stored in the temporary folder. 
     Preferably, between the step S 605  and the step S 606 , it may further include: 
     adjusting, the size and/or location of each target print image box in the page to be printed; and/or 
     deleting the selected target print image box in the page to be printed. 
     The technical solution of this example can combine the method according to the Example One, including an Android user interface, a channel display window and a transparent annotation window configured to display an annotation. The channel display window is arranged on the Android user interface, and the size and location of the channel display window is adjustable. The transparent annotation window may overlay the channel display window. 
     In addition, the print area should be determined before printing the image with an annotation or without annotation. Preferably, the acquiring print areas based on the touch point information may include: 
     extracting starting point and end point coordinates from the touch point information; and 
     drawing a frame between the starting point and the end point to form the print image box, and storing the print image box in the temporary folder. 
     Outputting the whole screen or the whole channel display window as a page to be printed can create a print task simply, but the page to be printed may undoubtedly include much unnecessary information, such as menu bar. Extracting starting point and end point coordinates from the touch point information to form a print image box can help the user to select a print area independently, to save paper and print cartridge. 
     In outer to further save the printing paper, the target print image boxes to be printed can be selected from the temporary folder to be arranged on the same page to be printed. 
     If a print image box is arranged on a page to be printed, there may be some blank space left on the printed page, because the print image box is a mall area captured by the user. The plurality of print image boxes stored in the temporary folder can be arranged on the same page to be printed in this embodiment, so it can make use of the space of the printed page to save printing paper. Preferably, the user can select a target print image box from the temporary folder and arrange the print areas of a number of channels which are related to each other on the same page to be printed, which is convenient for the user to read and compare to enhance the user experience. 
     Adjusting the size and/or location of each target print image box in the page to be printed; and/or 
     deleting the selected target print image box in the page to be printed. 
     In addition, after selecting the target print image boxes and arranging the target print image boxes on the same page to be printed, the user can adjust the size of each target print image box in the page to be printed by zooming, to save space. The user can also adjust the location of each target print image box in the page to be printed by dragging, to edit the space of the page to be printed. When the user needs to cancel a certain print image box, the user may remove the print image box by a deletion operation. 
     Finally, when the print task has been output and completed, the print image boxes corresponding to the print areas stored in the temporary folder can be deleted. Preferably, the system may delete the print image boxes just stored in the temporary folder to save storage space. Alternatively, the user can store the relevant files which have been printed in a fixed folder for later calling.
