Problems solved by technology

It can be seen that the first processing scheme still has defects such as increasing the burden on the video system and not being able to adjust the additional information in real time.
In addition, encoding the mixed image is equivalent to the second compression of the original video data, and video compression usually causes image distortion, thus damaging the image quality

Embodiment Construction

[0028] figure 1 is a flowchart of an embodiment of the method for displaying additional information in the main window of the present invention. More specifically, this embodiment illustrates the present invention by taking displaying a video and additional information of the video as an example. Such as figure 1 As shown, in step S100, the original video data of the video is read from the video source, and the original video data is decoded to obtain a video image. The video source can be a remote video source such as a video server, or a local video source such as a hard disk of a computer or a DVD disc. The original video data may be in a media stream format or in other formats. The decoded video image may be a still image or a dynamic image composed of image frames.

[0029] In step S102, a main window is created in the display area, and the above-mentioned decoded video image is displayed in the main window.

[0030] In step S104, the position parameter of the main win...

Abstract

The present invention provides a method and system for displaying additional information in the main window. The method includes: creating a main window, and displaying the background content in the main window; creating sub-windows in the main window, and overlapping the sub-windows on the main window; reading the display property information of the additional information associated with the background contents; determining the display additional information is required according to the display property information, if it is required, displaying the corresponding additional information in the sub-windows. The system includes a data-processing module (201) for reading background content, an additional information processing module (203) for reading the additional information data, a window processing module (205) for creating the main window and the sub-windows, and a display processing module (207) for displaying the background content in the main display window and displaying the additional information in the sub-windows. The present invention can save system costs, reduce the burden of the system, and improves the efficiency of the player.

Description

technical field [0001] The present invention relates to a method and system for displaying additional information in a main window. Background technique [0002] The additional information displayed in the main window can be used to mark the content currently displayed in the main window, explain the currently displayed content, help the user understand the currently displayed content, provide an interactive interface to respond to the user's input content, and so on. Common additional information includes mark information (such as station mark), description information (such as copyright statement, rebroadcast description), advertisement content, etc. that appear in the main window. [0003] In the field of display based on operating systems such as Windows, Linux, and embedded systems with GUI (graphical user interface), the additional information of the main window is mainly displayed through synthesis technology. The main principle of the synthesis technology is to synth...
