When a user watches television programs, the user can directly switch channels by finding corresponding channels in the channel list, and the method is convenient and quick. On a television, the focus can only be switched sequentially through the up-down keys of a remote controller, and for part of markets with a large number of channels, it is very time-consuming for a user to select channels only by using the up-down keys. And once moved to the bottom of the page, the entire page needs to be scrolled if one wants to go back to the beginning.

In order to solve the above technical problem, an embodiment of the present application provides a method for circularly turning pages of a list, where the method includes:

In some embodiments, as shown in FIG. 11, the user may implement the function of turning pages of the list by pressing the page up and page down keys on the control device.

In some embodiments, the step of pressing a page down key on the control device by the user to control the display to display the display list after page turning specifically includes:

the absolute position of the current selector selection control is M _ old, the relative position of the current selector selection control is M, the number of display lists is N, and the number of the whole lists is N. It can be specifically understood that: each display list can display n pieces of data by default; the relative position of the control currently selected by the user is m, the relative position is determined from 0, the relative position is 0,1,2.. N-1 from top to bottom, and all data in the whole list are N; the absolute position of the control currently selected by the user is M _ old, the absolute position is determined from 0, and the absolute position is 0,1,2.. N-1 from top to bottom.

Determining the absolute position to be determined of the selector selection control after turning down the page according to the absolute position of the current selector selection control and the number of the display lists;

in some embodiments, the absolute position to be determined M _ new '= M _ old + n, where M _ new' is the absolute position to be determined of the selector selection control after paging down.

in some embodiments, if M _ new '≦ N-1, M _new = M _new'; where M _ new is the actual absolute position of the selector selection control after flipping down.

In some embodiments, to ensure uniformity of data processing, the actual absolute position of the post-page down selector selection control may be determined by: m _ new = (M _ new' + N)% N.

at this point, the condition of M _ new-M + N < = N is satisfied, and offset = M _ new-M, where offset is the absolute position of the first visible control in the display list.

Determining a display list after page turning according to the absolute position of the selector selection control after page turning down and the absolute position of the first visible control; and controlling a display to display the display list after the page turning.

As shown in fig. 12, the whole list, the first display list, the second display list, the third display list, and the fourth display list are arranged in order from left to right. The total number of the data items (0 to 14) is 15 in the entire list, and 6 data items are displayed one page. As shown in fig. 5, the current display interface is displayed, where the display list corresponds to a first display list, and the relative position of the selector selection control 504, that is, the current selector selection control, is 1; when the user presses the page down key on the control device as shown in fig. 11, the current display interface is displayed as shown in fig. 6, the display list corresponds to the second display list, and the relative position of the selector selection control 510, i.e., the current selector selection control, is 1. The method for determining the absolute position of the selector selection control after flipping down and the absolute position of the first visible control in the display list is as follows:

as can be seen from fig. 5 and 12, M _ old =3,m =1,n =6,n =15;

since page down, M _ new' = M _ old + n =3+6=9;

since M _ new '≦ N-1, M _ new = M _ new' =9;

M_new-m+n＝9-1+6＝14，14＜＝N，offset＝M_new-m＝9-1＝8。

given that the absolute position of the selector selection control after flipping down is 9 and the absolute position of the first visible control in the display list is 8, a user interface such as that shown in FIG. 6 is available.
