Input detects in real time to vision signal for step S200, intelligent television, in the time vision signal input being detected, judges whether vision signal is analog signal.
Obviously, vision signal is divided into data signal and analog signal, and analog signal is again YPbPr signal, VGA signal or CVBS signal. In the time that vision signal is a kind of in YPbPr signal, VGA signal or CVBS signal, can not directly transfers to corresponding viewing area and play, but first be converted into after data signal in transmission.
Step S300, in the time that vision signal is analog signal, described analog signal is converted into after HDMI signal by Si8784 model chip, by HDMI signal input part transfer to corresponding viewing area and show.
Analog signal can be converted into HDMI signal by Si8784 model chip, play again for HDMI signal all unified vision signals all in intelligent television. This makes vision signal no matter be data signal, or analog signal, all can on intelligent television, play.
Step S400, in the time that vision signal is not analog signal, by described vision signal by HDMI signal input part transfer to corresponding viewing area and show.
When concrete enforcement, described vision signal is first transferred to corresponding viewing area and is shown by HDMI signal input part again after Si9687 model chip transforms.
Equally, be converted into after HDMI signal by Si8784 model chip in analog signal described in step S300, after also needing to transform by Si9687 model chip, transfer to corresponding viewing area and show by HDMI signal input part again.
Further, described step S400 specifically comprises:
Step S401, in the time that vision signal is not analog signal, judge whether this vision signal is 4K2K signal;
Step S402, in the time that vision signal is 4K2K signal, by HDMI signal input part transfer to the first viewing area and show;
Step S403, in the time that vision signal is not 4K2K signal, by HDMI signal input part transfer to corresponding viewing area and show.
In step S403, in the time that vision signal is not 4K2K signal, transfers to the second viewing area, the 3rd viewing area or the 4th viewing area by HDMI signal input part and show, show so long as not transferring to the first viewing area.
Visible, in the present invention multi-channel video signal input simultaneously and Overlapping display at same screen, realize appreciating in key frame, monitor other channel signal, and many dynamic menus smooth playing, realize the preview simultaneously of the little picture of multiple source.
Based on said method embodiment, the present invention also provides a kind of system that realizes of many pictures preview, and as shown in Figure 2, it comprises:
