Problems solved by technology
When dealing with these special cases, the original cursor system cannot meet the new design requirements
Moreover, the underlying system of the existing set-top box allows the application program to directly monitor the button operation of the remote control, so this provides the possibility for the APP to realize cursor management by itself.
[0003]
In summary, there are obviously inconveniences and defects in the actual use of the existing technology, so it is necessary to improve

The invention belongs to the technical field of televisions and provides a cursor control method and system based on a television application program. The method comprises the steps that a cursor coordinate system is set up, after the television application program is uploaded to a screen, all buttons on the screen are converted into cursor nodes, the cursor nodes are arranged according to a two-dimensional rectangular coordinate system, and all the cursor nodes are added to a corresponding set; the cursor is controlled, and a cursor manager of the television application program is used for monitoring key operation of a remote control so as to control the cursor to be moved and / or displayed on the cursor nodes. Accordingly, the cursor can be controlled and displayed more flexibly, preferably, multiple interfaces are provided for application program operation, the application program can be developed more easily, and the rich display effect is possibly achieved.
Description
technical field [0001] The invention relates to the technical fields of television and multimedia, in particular to a cursor control method and system based on television application programs. Background technique [0002] As we all know, the input device of the TV is the remote control, and the same is true of the Internet TV connected to the set-top box. On the computer, by moving the mouse to click, on the TV APP (Application, application program), the cursor frame can only be moved to the desired position (button) by the "Up / Down / Left / Right" buttons on the remote control, and then Click "OK" to perform related operations. In the underlying system of the existing set-top box, the logic for the remote control to control the movement of the cursor is determined according to the position of the "button" on the screen. For example, press the "Left" key to move the cursor frame to the left button. "Right" moves to the button on the right. However, as more and more special ...
