System and method for displaying on-screen menus of television

Abstract

The invention provides a system for displaying on-screen menus of a television, which comprises a main control chip, an on-screen display (OSD) engine, a mixer, a display processing module, a memory processing module, a memory and a zoom module, wherein the main control chip is used for making the OSD engine generate the on-screen menus according to an OSD request, the memory processing module is used for selectively saving the on-screen menus in the memory in a picture form according to the type of a video signal, and the zoom module is used for zooming the on-screen menus in the picture form, then outputting on-screen menus to the mixer for mixing, and finally outputting the on-screen menus to the display processing module for display. According to the system and a method for displaying the on-screen menus of the television, OSD containing fill color, characters and icons is comprehensively zoomed and is favorably output without changing the size and the shape through specific conversion of a three-dimensional (3D) display screen, so that the zoom of an OSD region containing the fill color, the characters and the icons is free from the limitation of the performance of the OSD engine.

Description

technical field [0001] The invention relates to a TV menu display technology, in particular to a TV screen menu display system and a display method thereof. Background technique [0002] Since the end of 2009, three-dimensional (3D) movies have been warming up rapidly under the enthusiasm of all walks of life. In this context, major domestic and foreign TV manufacturers are also actively investing in the development of 3D TV. 3D TVs can be divided into many types according to the different technologies used. Among them, there is a time-sharing shutter method that uses the combination of the main control chip and the display screen. The video signal pushed by the chip is stretched twice in the horizontal (vertical) direction and then merged. In this case, the video achieves a complete 3D output, but the on-screen display (OSD) will appear horizontal (vertical). ) direction is doubled, so that the OSD is very unsightly, and will cause part of the OSD to stick out of the scre...

Problems solved by technology

3D TVs can be divided into many types according to the different technologies used. Among them, there is a time-sharing shutter method that uses the combination of the main control chip and the display screen. The video signal pushed by the chip is stretched twice in the horizontal (vertical) direction and then merged. In this case, the video achieves a complete 3D output, but the on-screen display (OSD) will appear horizontal (vertical). ) direction is doubled, so that the OSD is very unsightly, and will cause part of the OSD to stick out of the screen, so that the user cannot see the complete OSD menu

[0004] In the above 3D mode, using the OSD engine's own capabilities and the above-mentioned technology related to icon processing cannot solve the scaling of the specified direction of the OSD area including characters and fill colors.

In the current state of technology, in order to prevent the above-mentioned OSD from being abnormal or protruding, it is possible to manually create multiple sets of OSD fonts (inconsistent horizontal and vertical ratios), and then cooperate with icon scaling to complete, but this takes a lot of time to do. Fonts, FLASH space will also increase a lot
