Device.In the same big multiple windows of screen display, multiple video sources using more and more extensive, this is just to the place of image processor
Reason method and processing speed are put forward new requirements, and requiring each window in display screen can be without rank superposition and any position
Dragging requires to reach seamless switching to the switching of each video source.
Existing video seamless switching mode mainly there are several types of:
Mode one, by being cached to input source multiframe, when image switching will output picture freeze in original picture, it is to be switched
Input source frame stabilization, then it will be outputted to new video source, this method needs biggish caching bandwidth, and the window exported
Mouth quantity has limitation.
Mode two, output picture is by main view frequency source and the superposition of the second video source constitutes or referred to as PIP picture-in-picture, according to two
1 is set by the gain of key frame when the display of a picture, and the gain of another picture is set as 0, by the second view when image switching
The gain of frequency source is increased up to 1, while key frame gain being reduced to 0, to realize seamless switching.This method also needs
The caching bandwidth doubled supports, in output there are when multiple windows, when the above video source, caching bandwidth is multiplied.
Mode three, system is by Video input card, video output card and video-splicing card composition, by the various of Video input card
Video source does normalized into unified video format, realizes scaling, splicing and the switching of video in splicing card or sync card,
This mode hardware cost hands over height, and the stackable number of windows of output end is limited.
