METHODS FOR OPERATING INTERACTIVE WHITEBOARDS AND APPARATUSES USING THE SAME
First Claim
1. A method for operating interactive whiteboards, performed by a processing unit of a control node, comprising:
- providing a connected-device display region, a multi-screen layout region and a whiteboard display region on an interactive display device, wherein the multi-screen layout region is segmented into a plurality of first blocks, the whiteboard display region is segmented into a plurality of second blocks and each first block is identical to one second block;
after detecting that an icon of the connected-device display region is dragged and dropped into one first block of the multi-screen layout region, obtaining a network address associated with the icon;
obtaining a first TCP (Transmission Control Protocol) port number associated with the first block comprising the dropped icon;
transmitting a first ready notification comprising the first TCP port number to the network address;
receiving first screen data with the first TCP port number; and
displaying the first screen data on the second block of the whiteboard display region, which is associated with the first block comprising the dropped icon.

Abstract
The invention introduces a method for operating interactive whiteboards, performed by a processing unit of a control node, which contains at least the following steps. A connected-device display region, a multi-screen layout region and a whiteboard display region are provided on an interactive display device. After detecting that an icon of the connected-device display region is dragged and dropped into a block of the multi-screen layout region, a network address associated with the icon is obtained. A TCP port number associated with the block of the connected-device display region, which contains the dropped icon, is obtained. A ready notification containing the TCP port number is transmitted to the network address. Screen data with the TCP port number is received. The screen data is displayed on a block of the whiteboard display region, which is associated with the block of the connected-device display region.

11. An apparatus for operating interactive whiteboards, comprising:
-
an interactive display device, providing a connected-device display region, a multi-screen layout region and a whiteboard display region, wherein the whiteboard display region is segmented into a plurality of second blocks and each first block is identical to one second block; a communications interface; and a processing unit, coupled to the interactive display device and the communications interface, and after detecting that an icon of the connected-device display region is dragged and dropped into one first block of the multi-screen layout region, obtaining a network address associated with the icon;
obtaining a first TCP (Transmission Control Protocol) port number associated with the first block comprising the dropped icon;
transmitting a first ready notification comprising the first TCP port number to the network address;
receiving first screen data with the first TCP port number via the communications interface; and
displaying the first screen data on the second block of the whiteboard display region, which is associated with the first block comprising the dropped icon. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
