Embodiment 1

[0050] see figure 1 , figure 1 It is a method flow chart of the first embodiment of an image overlay display method of the present invention.

[0051] In the first embodiment, the superimposed display method of the image includes:

[0052] S101, acquiring the video frame of the anchor video output in full screen;

[0053] This method is mainly applied to terminals such as digital TVs and computers.

[0054] Within the preset duration, according to the preset sampling period, several video frames of the currently full-screen anchor video are read from the video buffer in real time, for example, a frame of current video is read from the video buffer of the anchor video every 1 second. The video frame of the host video that is being played is cached, and 5 video frames of the host video can be read within 5 seconds.

[0055] S102. According to the size of the small window when the auxiliary image is output, obtain the area where the content of the video frame has the smallest...

Embodiment 2

[0063] see figure 2 , figure 2 It is a method flowchart of the second embodiment of an image overlay display method of the present invention.

[0064] In the second embodiment, the superimposed display method of the image includes:

[0065] S201. Within the preset duration, according to the preset sampling period, read a plurality of video frames of the currently full-screen anchor video from the video buffer;

[0066] Continuing the above routine, within 5 seconds, read 5 video frames of the anchor video currently playing in full screen from the video buffer at 1 frame / second.

[0067] S202, acquiring the size of the small window when the auxiliary image is output;

[0068] S203. Divide the area space when the video frame is output in full screen to obtain two areas with equal areas;

[0069] According to the size of the small window, an iterative algorithm is used to find out the area with the smallest dynamic change in content, that is, the area with the smallest dyna...

Embodiment 3

[0087] see image 3 , image 3 It is a structural block diagram of the first embodiment of an image superimposing display system according to the present invention, and the parts not described in detail in the system embodiment refer to the method embodiment.

[0088] In the third embodiment, the image superimposition display system includes:

[0089] Video frame acquisition module 01, used to obtain the video frame of the anchor video output in full screen;

[0090] The above-mentioned video frame is obtained from the set-top box terminal and the cache area of ​​the anchor video, and cached.

[0091] The target area acquisition module 02 is used to acquire the area where the content of the video frame has the least dynamic change from the area space of the full-screen output of the video frame according to the small window size when the auxiliary image is output, and use the area as the target area ;

[0092] A superimposed display module 03, configured to superimpose and...

Abstract

The invention discloses an image display method and system through superposition. The method comprises following steps of obtaining video frames of a main playing video output in a full screen; obtaining an area from area space when the video frames is output in the full screen according to a small window size when auxiliary images are output, wherein the dynamic change of the contents of the video frames in the area is the minimum; taking the area as a target area; displaying the auxiliary images in the target area through superposition; and displaying the auxiliary images through superposition in the area in which the dynamic change of the contents of the video frames output in the full screen is the minimum. According to the image display method and system through superposition provided by the invention, the visual effect of the main playing video is not influenced, moreover the auxiliary images are displayed, and the user experience is improved.

Description

technical field [0001] The present invention relates to the technical field of video playback, in particular to an image superimposition display method and system. Background technique [0002] With the increasing development of digital TV technology, the traditional way of watching TV is changing, and digital TV services are diversified. Large-sized giant-screen TVs provide good conditions for the expansion of digital TV services. During the playback of program videos, static pictures or dynamic images can be presented at certain positions in the video images to provide users with a Better viewing methods and new experience effects. For example, in the process of TV broadcasting, photos can be presented to users in real time in the form of pictures, and comment information on programs watched by users can be presented. In the process of video playback, an area can also be selected Simultaneously predict and play to the user the content of programs that are being played by ...
