Display method and display system of video streams

A display system of video streams, comprising:

• a controller and a display, wherein the controller is configured to:
• obtain a plurality of video streams associated with a plurality of video capture devices;
• determine a first plurality of video streams associated with a first escalator among the plurality of video streams;
• determine positions of a first plurality of video capture devices associated with the first plurality of video streams among the plurality of video capture devices over the first escalator;
• determine a first display order of the first plurality of video streams in a first plurality of display windows based on the determined positions of the first plurality of video capture devices over the first escalator;
• and
• control the display to display the first plurality of video streams in the first plurality of display windows according to the first display order,
• wherein determining the first display order of the first plurality of video streams in the first plurality of display windows based on the determined positions of the first plurality of video capture devices over the first escalator includes determining the first display order based on a low-to-high position order or a high-to-low position order of the first plurality of video capture devices over the first escalator.
