Wherein, a full frame output in the GIS display window and the video playback window is selected, and another is in screen
First predeterminated position reduces the step of output, comprising:
If what is chosen in the GIS display window and the video playback window is the GIS display window, obtain and current
The corresponding current shift position point of video frame；
Image information within the preset range of the current shift position point is amplified in the second predeterminated position of screen defeated
Out, second predeterminated position is far from first predeterminated position, thus the video playback window after reducing fail to block it is described
Image information within the preset range of current shift position point；
If what is chosen in the GIS display window and the video playback window is the video playback window, full frame output
It the video playback window and is reduced in the first predeterminated position of screen and exports the GIS display window.
6. a kind of video display devices characterized by comprising
First output module, for screen output GIS display window and video playback window；
Module is transferred, for transferring existing video file, the video file includes multiple video frames, each video frame packet
Include location information and temporal information；
Generation module, for generating shift position point according to the positional information and generating play position according to the temporal information
Point, the shift position point and play position point of the same video frame correspond；
Module is formed, trajectory line is formed for all shift position points and all play position point forms video progress bar；
Second output module, for exporting the trajectory line to the GIS display window and the output video progress bar and working as
Preceding video frame is to the video playback window；
Third output module, for selecting a full frame output in the GIS display window and the video playback window, and
Another reduces output in the first predeterminated position of screen；
Wherein, third output module includes:
Acquiring unit, if being the GIS display window for what is chosen in the GIS display window and the video playback window
Mouthful, full frame output GIS display window and the first predeterminated position of screen reduce output video playback window, acquisition and current video
The corresponding current shift position point of frame；
Amplify output unit, for by the image information within the preset range of the current shift position point in the second pre- of screen
If position amplifies output, second predeterminated position is far from first predeterminated position, so that the video playing after reducing
Window fails to block the image information within the preset range of the current shift position point；
Third output module, if be also used to choose in the GIS display window and the video playback window is the view
Frequency broadcast window, it is full frame to export the video playback window and reduce the output GIS display window in the first predeterminated position of screen
Mouthful.
