Method for solving dynamic switch of GUI graphical system under various display standard

Abstract

The invention discloses a method for the dynamic switching of the GUI graphics system under multiple display standards. The core idea is to separate a graphics mapping zone of the GUI system from a display zone, to implement the respective processing on the two zones and to dynamically update the data of the GUI mapping zone to the display zone, resulting in that the results that the target display zone does not need to be taken into account within a certain extent for the operation process of CUI within the mapping zone but only the GUI expression of the application business is needed to be noted; the real-time adjustment on the size and the ratio of the height to width of the display zone can be realized according to the target display environment; by the establishment of the mapping relation between the mapping zone and the display zone, a graphics transform method is applied to realize the dynamic updating of data within a dual memory area, thus simplifying the GUI system mapping process when switching from one display standard or a mapping environment to another display environment and solving the problem that the classified expression on the graphic elements is required according to the display requirements of multi standards or mapping types in course of the typical GUI system mapping.

Description

【Technical Field】 [0001] The invention relates to the technical field of drawing processing and display of a GUI graphics system, in particular to a method for solving the dynamic switching of the GUI graphics system under multiple display standards. 【Background technique】 [0002] In the process of digital TV technology development, there has always been a situation where multiple standards (NTSC and PAL) and multiple standards (SD and HD) coexist. These different video formats and display standards directly determine the GUI graphics system in the product. The size and proportion of the final display screen. The design and application of GUI graphics system has always been one of the most basic and important tasks in the field of digital technology applications. Due to the differences in the display output of various standards (NTSC, PAL, 1080I / P, 720P, etc.), the GUI graphics system in the product needs to adjust the display size and proportion in real time according to the t...

Problems solved by technology

However, such a GUI system that integrates the drawing area and the display area is difficult to dynamically support the conditions defined by the display standards of different display sizes and aspect ratios.

This undoubtedly seriously increases the complexity of the drawing process of the GUI system, and it is not conducive to the GUI system to increase or decrease the support for a certain display standard.
