Embodiment Construction

[0045] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0046] The invention provides a method for displaying an ultra-high-definition OSD menu.

[0047] refer to figure 1 , figure 1 It is a schematic flowchart of the first embodiment of the method for displaying an ultra-high-definition OSD menu in the present invention.

[0048] In the first embodiment, the display method of the ultra-high-definition OSD menu includes:

[0049] Step S10, when starting the ultra-high-definition application, allocate processing memory from the video memory of the graphics processor;

[0050] In this embodiment, when an ultra-high-definition application is started, the processing memory is allocated directly from the memory of the Graphics Processing Unit (GPU), that is, the video memory, instead of applying for the processing memory from the system memory, and the processing memory allo...

Abstract

The invention discloses a display method of an ultra high definition OSD (on-screen display) menu. The method comprises following steps of when an ultra high definition application is started, allocating a processing memory from the video memory of a graphics processing unit; carrying out model rendering to the graphics of the ultra high definition application in the allocated processing memory by the graphics processing unit, thus obtaining an ultra high definition application graphics layer; carrying out aliasing processing to the ultra high definition application graphics layer and a preset application graphics layer, obtaining a menu graphics layer; and displaying the menu graphics layer through the OSD menu. The invention also discloses a display method of the ultra high definition OSD (on-screen display) menu. According to the method and the device, under conditions that the existing hardware platform is limited and the system memory bandwidth has a bottleneck, the display frame rate of the ultra high definition OSD menu is improved; and the user operation fluency and the experience feeling of the user to the ultra high definition OSD menu are improved.

Description

technical field [0001] The invention relates to the technical field of menu display, in particular to a method and device for displaying an ultra-high-definition OSD menu. Background technique [0002] With the development of display technology, ultra-high-definition TVs such as 4K2K TVs have gradually entered the mainstream TV market, but most 4K2K TVs can basically only play 4K2K ultra-high-definition videos or pictures, and the OSD (on-screen display, Screen menu adjustment method) The menu is still displayed after stretching the resolution of 1080p. This way of stretching and displaying will greatly affect the clarity of the OSD menu display, making the OSD menu unable to achieve 4K2K Ultra HD resolution visuals. Although there are 4K2K TVs that can display 4K2K ultra-high-definition resolution OSD menus, the display frame rate of 4K2K TVs when displaying 4K2K ultra-high-definition resolution OSD menus is very low due to limited hardware platforms and bottlenecks in sys...
