Problems solved by technology

Since the display area of ​​the OSD, the text font of the OSD and the icon of the OSD are all fixed, this cannot meet the needs of users
If the user is watching TV at a place far away from the digital TV, and the user wants to operate the OSD at this time, the OSD area, the OSD text font and the OSD icon are too small to see the OSD text and icon clearly, so that the user cannot operate OSD, you must approach the digital TV until you can clearly see the text and icons of the OSD before you can operate the OSD
Therefore, the user will be limited by the distance when operating the OSD, which will bring inconvenience to the user when using the digital TV.

Embodiment Construction

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0020] figure 1 is a schematic flow chart of a scaling method of the present invention, such as figure 1 shown, including:

[0021] S101. Copy the OSD, and convert the copied OSD into video frames.

[0022] The data format of the OSD is different from the data format displayed in the video layer. It is necessary to convert the OSD into video frames before it can be displayed in the video layer.

[0023] It should be noted that copying the OSD here may be copying...

Abstract

Embodiments of the invention disclose a scaling method, which comprises copying an on-screen display (OSD), converting the OSD into a video frame, displaying the converted video frame, hiding the OSD displayed in the OSD layer, and scaling the displayed video frame. Correspondingly, embodiments of the invention also disclose a scaling device. With the invention, the user can adjust the OSD size, so as to free OSD operation from distance limitation and realize convenient digital TV operation.

Description

technical field [0001] The invention relates to the field of digital televisions, in particular to a scaling method and device. Background technique [0002] At present, users mainly set the functions and properties of the digital TV set by operating an on-screen adjustment menu (OSD, On-Screen Display), or operate a set-top box (STB, Set-Top Box). Since the area for displaying the OSD, the text font of the OSD and the icon of the OSD are all fixed, it cannot meet the needs of the user. If the user is watching TV at a place far away from the digital TV, and the user wants to operate the OSD at this time, the OSD area, the OSD text font and the OSD icon are too small to see the OSD text and icon clearly, so that the user cannot operate For OSD, you must approach the digital TV until you can see the text and icons of the OSD clearly before you can operate the OSD. Therefore, the user is limited by the distance when operating the OSD, which brings inconvenience to the user wh...
