Description
Technical Field

Background
With the development of the technology, more and more set top boxes are provided with touch screens, so that a user can control the set top boxes in a short distance by touching and can control the set top boxes in a long distance by a remote controller.
In general, when a user sends a signal to a set-top box by using a key remote controller, the set-top box is in a key mode to receive and process the signal; when a user touches a touch screen of the set top box to control the set top box, the set top box is in a touch mode to receive and process signals. When the set top box starts a touch mode, shielding a key mode; when the key mode is started, the touch mode is shielded, which is a compromise pseudo-dual control mode. When a user switches from using a remote controller to controlling the touch screen, the set top box is switched from a key mode to a touch mode, and at the moment, the set top box can normally process a touch signal of the user as long as a control on the touch screen can be clicked; however, when a user switches from controlling the touch screen to using the remote controller, the set-top box switches from the touch mode to the key mode, and when the set-top box processes an event generated by triggering a key for the first time by the user, there are many uncertainties in the focus falling of the key mode, especially for a page with a list, and focus logic after switching the mode may not be executed normally, resulting in a disordered page and abnormal use, and a seamless switching of dual modes may not be achieved at all, resulting in a very poor user experience.

Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only a part of the structures related to the present invention, not all of the structures, are shown in the drawings, and furthermore, embodiments of the present invention and features of the embodiments may be combined with each other without conflict.
Example one
Fig. 1 is a flowchart of a signal processing method according to an embodiment of the present invention, where the embodiment is applicable to a case where a set top box is controlled by a remote controller and a touch screen, and the method may be executed by a signal processing apparatus, and the apparatus may be implemented by software and/or hardware.
As shown in fig. 1, the method specifically includes the following steps:
and step 110, receiving an operation signal sent by a user, and determining the mode switching condition of the set top box.
In this embodiment, the set-top box is configured with a touch screen, and a user can click or slide the touch screen at a short distance to control the set-top box, or press the remote controller at a long distance to control the set-top box. The operation signal may be understood as an indication signal generated when a user clicks or presses a corresponding control through a remote controller or a set-top box touch screen when the user wants to control the set-top box, that is, the signal type of the operation signal may include a touch signal and a key signal. When a user sends an operation signal to the set-top box by using the key remote controller, the set-top box is in a key mode to receive and process the operation signal; when a user touches a touch screen of the set top box to control the set top box, the set top box is in a touch mode to receive and process the operation signal.
Specifically, when the set-top box receives the operation signal, the interaction mode to be entered by the set-top box can be determined according to the signal type of the operation signal, and the mode switching condition of the set-top box is determined by combining the interaction mode in which the set-top box is located before receiving the operation signal. When the operation signal is a touch signal, it indicates that the current moment of the user is the operation signal sent to the set-top box by clicking or sliding the touch screen, the set-top box will respond to the operation of the user in the touch mode, if the set-top box is in the touch mode before receiving the operation signal, the mode switching condition of the set-top box is that the set-top box is in the touch mode without switching, and if the set-top box is in the key mode before receiving the operation signal, the mode switching condition of the set-top box is that the key mode is switched to the touch mode. When the operation signal is a key signal, it indicates that the current moment of the user is the operation signal sent to the set-top box by pressing the remote controller, the set-top box will respond to the operation of the user in the key mode, if the set-top box is in the key mode before receiving the operation signal, the mode switching condition of the set-top box is that the set-top box is in the key mode without switching, and if the set-top box is in the touch mode before receiving the operation signal, the mode switching condition of the set-top box is that the set-top box is switched to the key mode in the touch mode.
And step 120, if the mode switching condition is that the touch mode is switched to the key mode, acquiring current page information, determining a focus control according to the current page information, and pointing the focus to the focus control from the transfer control.
Generally, when a set top box is in a touch mode, due to operations such as a user sliding a page and the like, a focus usually does not point to a definite control, the set top box is switched to a key mode at the moment, a key lifting event generated when a user presses a key can only be monitored under a common condition, but a key pressing event cannot be monitored, when the key pressing event is triggered, a signal processing system of the set top box already completes focus falling processing by default, but uncertainty of focus falling can cause page confusion or page jump, normal use cannot be realized, and user experience is influenced. It has been found that if there is a clear View control that holds focus in touch mode, the key press event when switching from touch mode to key mode can be clearly monitored.
In this embodiment, a relay control that can be focused in the touch mode may be set in advance in the page to be adapted to the dual control mode, and the relay control is focused when the set-top box is in the touch mode. When the mode switching condition of the set top box is that the touch mode is switched to the key mode, the page information of the current page of the touch screen of the set top box can be acquired, a focus control is determined in the current page, and the focus is directed to the focus control from the transit control.
And step 130, responding to the operation signal based on the focus control.
The operation type of the operation signal may include a focus moving operation, a determining operation, and/or a returning operation, among others.
Specifically, when a clear control exists in the current page of the touch screen of the set top box to be focused, that is, when a focus control exists, the operation instruction of the user can be responded based on the focus control. For example, if the user presses a down key of the remote controller, the operation type of the operation signal is the focus moving operation, and at this time, the focus may be moved down to a control below the focus control, so as to complete the operation instruction of the user.
Illustratively, a set of program list is displayed on the display screen of the set-top box, and there are 100 programs in the set of programs, that is, there are 100 lines of program data in the program list that can be displayed, and since the screen size of the touch screen of the set-top box is limited, a maximum of 5 program data can be displayed on the screen page. If a user slides a program list through a touch screen, program data of 50 th to 54 th lines in the list are displayed on the screen, the user wants to select program data of 51 th line in the list, and an operation signal is sent to a set top box by pressing down a key through a remote controller. After the technical scheme of the embodiment is used, when a user slides the program list through the touch screen, the transfer control is focused, when the user presses the down key through the remote controller to send an operation signal to the set top box, the system normally transmits the key pressing event, the event is intercepted after the event is received by the root layout, the focusing operation is completed according to the display condition of the current page, and therefore the problems of skipping and the like of the displayed page can be avoided.
According to the technical scheme of the embodiment, the mode switching condition of the set top box is determined by receiving the operation signal sent by the user; if the mode switching condition is that the touch mode is switched to the key mode, acquiring current page information, determining a focus control according to the current page information, and pointing the focus to the focus control from a transfer control, wherein the transfer control is a control pointed by the focus of the set top box in the touch mode; based on the focus control, the operation signal is responded, the problem that when the set top box is switched from the touch mode to the key mode to process an event generated by triggering a key by a user for the first time, the page is disordered and cannot be normally used due to uncertainty existing in the focus falling of the key mode is solved, seamless switching between the touch mode and the key mode of the set top box is achieved, and user experience is improved.
Example two
Fig. 2 is a flowchart of a signal processing method according to a second embodiment of the present invention. The present embodiment further optimizes the signal processing method based on the above embodiments.
As shown in fig. 2, the method specifically includes:
Specifically, if the latest operation signal received by the set-top box at the current time is a key signal and the operation signal received last time is a touch signal, the set-top box is in the touch mode when processing the last operation signal, and the set-top box will be in the key mode when processing the current operation signal, so that the mode switching condition of the set-top box is that the touch mode is switched to the key mode. It can be understood that the mode switching of the set-top box may also be a key mode switching to a touch mode, a touch mode no switching, and a key mode no switching. Since the embodiment mainly solves the problem of focus falling when the set top box is switched from the touch mode to the key mode, the other three mode switching situations are not described too much. Particularly, when the set-top box is just started, the set-top box can enter a touch mode by default, and the focus is dropped on the transfer control.
And step 230, acquiring information of the current page and determining the alternative controls in the current page.
The current page information can be understood as the page information displayed on the touch screen of the set top box at the current time, and the alternative controls are controls included in the current page and can be considered as controls which can be seen by a user through the touch screen at the current time.
Generally, a user only wants to control the controls that the user can see, so that the information of the current page can be acquired, and the controls in the current page are all determined as alternative controls.
And 240, determining a focus control in each alternative control according to the control position of each alternative control.
Specifically, because the positions of the alternative controls distributed in the current page are different, in general, people have viewing habits from left to right, from top to bottom, or from the middle to the periphery and the like when seeing a picture, and therefore, a reasonable focus-falling rule can be specified according to different page scenes, and one focus control is determined in the alternative controls.
Optionally, step 240 may be implemented by: determining the control middle point of each alternative control, and determining the alternative control corresponding to the control middle point closest to the page coordinate origin as the focus control.
It will be appreciated that a page coordinate system is established in the current page for identifying the display position of each control. Because each alternative control has a certain size, the distance from the midpoint coordinate of the alternative control to the page coordinate origin can be selected to represent the distance between the alternative control and the page coordinate origin. When a page coordinate system is established, the origin of the page coordinate is set at the upper left corner of the page, and the selected focus control is the control closest to the upper left corner of the page; when the page coordinate system is established, the page coordinate origin may also be set at the page center, and the selected focus control is the control closest to the page center.
And step 250, pointing the focus to the focus control from the transfer control.
Specifically, since the relay control is focused when the set-top box is in the touch mode before, the focus can be pointed to the focus control by the relay control at this time.
And step 260, determining a target control corresponding to the operation signal according to the operation type of the operation signal and by combining the focus control.
The target control can be understood as a control to which the final focus points after responding to an operation instruction of a user.
Specifically, since a user may press a direction key, a confirm key, a return key, or the like on the remote controller, the meaning of an instruction represented by each key is different, and the situation that the focus needs to be moved is different, it is necessary to determine a target control corresponding to the operation signal based on the focus control according to the operation type of the operation signal.
Optionally, the implementation of this step can be divided into the following cases:
the first condition is as follows: and when the operation type of the operation signal is focus moving operation, determining the focus moving direction, and determining the next control of the focus control as a target control along the focus moving direction.
Specifically, when the user presses an up key, a down key, a left key, or a right key of the remote controller, the operation type of the operation signal is the focus moving operation, and the focus moving direction is consistent with the key pressing direction. When a user presses a key, the moving direction of the focus is downward, and the first control below the focus control is a target control; when a user presses an upper key, the moving direction of the focus is upward, and a first control above the focus control is a target control; when a user presses a left key, the moving direction of the focus is towards the left, and the first control on the left side of the focus control is the target control; when the user presses the right key, the moving direction of the focus is towards the right, and the first control on the right side of the focus control is the target control. Specifically, the focus movement direction may be re-determined to be up when the user presses the left key but there are no other controls to the left of the focus control, and correspondingly, the focus movement direction may be re-determined to be down when the user presses the right key but there are no other controls to the right of the focus control.
Case two: and when the operation type of the operation signal is a return operation, determining that the parent control of the focus control is the target control.
Specifically, when the user presses a return key on the remote controller, it may be determined that the operation type of the operation signal is a return operation, and at this time, the user wants to return to view a previous page of the current page.
Case three: and when the operation type of the operation signal is the determination operation, if the focus control has the sub-control, determining the sub-control with the minimum control sequence number as the target control, and otherwise, determining the focus control as the target control.
Specifically, when a user presses a determination button on the remote controller, it may be determined whether the focus control includes a next-level sub-control, if the focus control includes the sub-control, the sub-control with the smallest control sequence number may be selected as the target control, and if the focus control does not include the sub-control, that is, the focus control is the bottommost control, the focus control may be used as the target control.
And 270, pointing the focus to the target control, and displaying a display page where the target control is located.
Specifically, the focus is transferred from the focus control to the target control, and if the operation type of the operation signal is a focus moving operation, the display page can be moved towards the focus moving direction; if the operation type of the operation signal is a return operation, displaying a target control, namely a page where a parent control of the focus control is located; if the operation type of the operation signal is the determination operation, the page where the target control is located can be displayed, and if the target control contains a program playing inlet, the program can be played.
According to the technical scheme of the embodiment, by receiving an operation signal sent by a user, when the mode switching condition of the set top box is determined to be that the touch mode is switched to the key mode, current page information is obtained, alternative controls in the current page are determined, a focus control is determined in each alternative control according to the control position of each alternative control, a focus is directed to the focus control from a transfer control, a target control corresponding to the operation signal is determined according to the operation type of the operation signal and by combining with the focus control, the focus is directed to the target control, and a display page where the target control is located is displayed. According to the method and the device, the problem that when the set top box is switched from the touch mode to the key mode to process the event generated by triggering the key for the first time by the user, the page is disordered and cannot be normally used due to uncertainty of focus falling of the key mode is solved, seamless switching between the touch mode and the key mode of the set top box is achieved, and user experience is improved.
