Video split device
Video is adaptively allocated between different screen parts depending on its content. The content of the video is analyzed, and a determination is main about whether the video should be displayed in a large part of the screen or a smaller part of the screen. The screen split can be adaptively displayed, or the position where the video is display can be changed.
1 . A system, comprising:
a first element which characterizes content of a video source, where the video source which includes information for first and second separated display parts; and
a display driver which produces outputs for said first and second display parts to be separately displayed from one another on separate portions of a display screen with said first and second display parts displayed on non-overlapping portions on said display screen, said first and second display parts being separated based on said determination of said content, where the determination is a type of content in each of said first and second display parts, and where said display driver sets a portion size of the display said first display part will occupy relative to an amount that said second display part will occupy, and where at a first time when a first content is displayed as said first display part, said first and second display parts are displayed with a first size ratio therebetween formed of first and second outer shapes; and where at a second time when a second content is displayed as said first display part, said first and second display parts are displayed with a second size ratio therebetween, and with said first and second outer shapes, where said second size ratio is different than said first size ratio.
2 . A system as in claim 1 , wherein said first and second display parts occupy areas on a single screen.
3 . A system as in claim 1 , wherein one kind of said characterized content is content which is indicative of a commercial, where said commercial as said first display part sets said first size ratio to a size that provides a smaller portion for the display part displaying the commercial, and another content as said first display part sets said second size ratio.
4 . A system as in claim 1 , wherein one kind of said characterized content is a content indicative of an amount of action within the scene, where a first amount of action in the scene in said first display part sets said first size ratio, and a second amount of action in the scene in said first display part sets said second size ratio, where said second amount of action in the scene is more action than the first amount of action, and said first display part occupies a greater percentage of the screen responsive to said second amount of action being detected.
5 . A system as in claim 1 , wherein said characterized content is a specified action that is automatically characterized.
6 . A system as in claim 1 , wherein said one kind of characterized content is a specified action occurring in a sports scene that is automatically characterized, which causes a larger area of said display part to be used to view said sports scene.
7 . A system as in claim 1 , wherein said display driver limits a rate of change of the viewing size per specified time.
8 . A system, comprising:
a video characterizing system which automatically characterizes the content of video; and
a video driver, which changes the size of viewing said video based on said content which was automatically characterized, wherein said video driver limits a rate of change of the viewing size which can be carried out per specified time.
9 . A system as in claim 8 , wherein said video driver causes the video to be separately displayed in two parts on separate portions of a display screen with first and second display parts displayed on non-overlapping portions on said display screen, said first and second display parts being separated based on said characterizing of said content, where the characterizing is a type of content in each of said first and second display parts, and where said display driver sets a portion size of the display said first display part will occupy relative to an amount that said second display part will occupy, and where at a first time when a first content is displayed as said first display part, said first and second display parts are displayed with a first size ratio therebetween formed of first and second outer shapes; and where at a second time when a second content is displayed as said first display part, said first and second display parts are displayed with a second size ratio therebetween, and with said first and second outer shapes, where said second size ratio is different than said first size ratio.
10 . A system, comprising:
a video characterizing system which automatically characterizes content of video; and
a video driver, which changes the size of viewing said video based on said content which was automatically characterized without changing a form of an outer shape of said video, further comprising identifying a category of content, and determining from said category whether an amount of change of the viewing size which can be carried out in a specified time should be limited, and if so, limiting an amount of change which can be carried out in any specified time, and if not, allowing said amount of change to be carried out without said limiting.
11 . A system as in claim 8 , wherein said characterizing comprises detecting commercials and reducing a size of a screen portion that is associated with displaying said commercials.
12 . A system as in claim 7 , wherein said characterizing comprises detecting action within a scene and increasing a size of a screen portion that is associated with displaying said action.
13 . A system as in claim 7 , wherein said characterizing comprises detecting a specified action within a scene and increasing a size of a screen portion that is associated with displaying said action.
14 . A method, comprising:
operating a video system which includes first and second viewing functions which includes a main viewing part and an auxiliary viewing part, smaller than said main viewing part;
determining content to go into said main viewing part and said auxiliary viewing part;
changing sizes of said main viewing part and said auxiliary viewing part; and
limiting a rate of change of the viewing size which can be carried out per specified time.
15 . A method as in claim 14 wherein said determining comprises detecting commercials in a first video within the main viewing part, and changing said first video to the auxiliary viewing part responsive to said determining a commercial.
16 . A method as in claim 14 , wherein said first and second viewing functions include a picture in picture function with said main viewing part being the overall view, and said auxiliary viewing part being a miniature view within the main viewing part.
17 . A method as in claim 14 , wherein said determining content comprises automatically detecting action within the main viewing part.
18 . A method as in claim 14 , wherein said determining content comprises automatically detecting a commercial within the main viewing part.
19 . A method as in claim 14 , wherein said determining content comprises detecting specified words within an audio track.
20 . A method as in claim 16 , wherein said determining content automatically determines the content, and further comprising adaptively sizing elements of the picture in picture based on said determining content.
