Embodiment Construction

[0035] In order to make the objectives, technical solutions, and advantages of the present invention clearer, the following further describes the present invention in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention.

[0036] figure 1 Shows the system structure of a set-top box menu 3D (Three-Dimensional) effect of the present invention. The system 10 includes a 3D modeling unit 11, a rotation control unit 12, a texture generation unit 13, a depth buffer unit 14, a color Filling unit 15 and texture display unit 16, where:

[0037] The 3D modeling unit 11 is used to construct a 3D model of a cube, determine the plane equations of each plane of the cube, and establish a vertex list of the cube. In the present invention, the 3D modeling unit 10 first determines a coordinate system, and constructs the X axis to b...

Abstract

The invention discloses a method for realizing set top box menu 3-D effect, comprising the following steps: building a cubic 3D model; confirming a plane equation of each plane of the cube; building an apex listing of the cube; designating a rotating shaft to rotate the cubic 3D model; calculating new location of the apex listing and confirming a new plane equation of each plane of the cube according to the new location of the apex listing; opening up a internal memory buffer zone, establishing a memory bitmap and drawing menu display content on the memory bitmap to form a chartlet; establishing depth buffer of the chartlet in a depth buffer zone; confirming position of a certain point on the chartlet according to the new plane equation of the cube and filling the color of the position of the point on the chartlet into depth buffer; finally displaying the chartlet on the screen.Based on the method and the system of the invention, the set top box menu enjoys 3-D and dynamic effect when propping up, blanking and selected.

Description

Technical field [0001] The invention relates to the field of digital television set-top boxes, in particular to a method and system for realizing a set-top box menu. Background technique [0002] The set-top box is a bridge between digital TV users and the outside world. The set-top box sends out the user's service request and receives the control information of the center system and compressed program information, and then decodes these MPEG (Moving Pictures Experts Group) transport streams And sent to the user's TV. To complete the EPG (Electronic Program Guide, electronic program menu) guide, the set-top box must first receive the electronic menu and display it on the user terminal. Now the pop-up, exit, and selection of the menus in ordinary set-top boxes are all flat maps or directly drawn using drawing functions. They are displayed as a whole after receiving the display command, or disappear as a whole after exiting the command, or change the selected item to a contrastin...
